Current project: CC-7567

"One, orders. You follow orders. They keep you alive. Two, you're part of a team. We look out for our buddies&mdash;I cover your back, you cover mine. And three, an officer rank doesn't give you automatic respect. You earn it. It's not just Skywalker's rank that makes us give him one hundred percent. It's because he treats us with respect, and he puts himself on the line with us."

- CC-7567, to Ahsoka Tano

CC-7567 was a veteran clone trooper captain who led the Grand Army of the Republic's famed 501st Legion during the Clone Wars. After undergoing extensive training to enhance his natural abilities, 7567 adopted the nickname "Rex" as a mark of individuality. Rex entered into Republic service in the opening battle of the Clone Wars, and his loyalty and fearlessness earned him a reputation as one of the best and toughest clones in the galaxy. As the captain of the 501st, Rex was assigned to Jedi General Anakin Skywalker, whose bravery and unorthodoxy in battle he came to share. He also befriended Clone Commander CC-2224, nicknamed "Cody," and the two clones and their respective Jedi Generals, Skywalker and Obi-Wan Kenobi, often led campaigns together on the front lines. In 21 BBY, after becoming acquainted with Skywalker's newly assigned Padawan, Ahsoka Tano, during the lengthy Battle of Christophsis, Rex led the 501st's Torrent Company in the following Battle of Teth. The unit's near-eradication there made it a battle that he would never forget.

Rex was soon redeployed with Skywalker and Tano, and he joined them in leading a string of 501st offensives at Bothawui, Skytop Station, JanFathal, and Kothlis. He also played a key role in repelling several Separatist attacks on Kamino, personally spearheading the interception of a Kamino-bound invasion fleet with Cody at Rishi Station and a defense of the clones' homeworld itself from a major Separatist incursion. Besides aiding in the containment of the Separatist-manufactured Blue Shadow Virus on Naboo, the liberation of Ryloth from the Confederacy, and the sabotage of a Separatist superweapon on Behpour, Rex participated in other key campaigns like the Second Battle of Geonosis, in which the Republic succeeded in crippling a series of Geonosian battle droid foundries, and the Battle of Saleucami, which led Rex to meet and come to respect the Clone Army deserter Cut Lawquane despite their differences.

Training and early career
"I've been in countless battles and lost many brothers. They were my family, my home."

- Rex reflects on his service in the war

The clone trooper who received the designation "CC-7567" was born around 31 BBY on the planet Kamino for service in the Grand Army of the Republic. A clone of the acclaimed bounty hunter Jango Fett, 7567's early life was largely made up of Kaminoan flash training. Like many other clone officers, 7567's confidence and leadership abilities were spotted early by the Kaminoan cloners, and he was put through additional training and intensive programmed learning to enhance his skills as a leader. After the completion of his training, 7567 took the nickname "Rex," although he elected to keep the name's origins to himself. In 22 BBY, Rex served on Geonosis with fellow trooper Denal and participated in the First Battle of Geonosis, fighting the breakaway Confederacy of Independent Systems and the forces of its massive Droid Army alongside the rest of the Jedi-led Republic Grand Army. Surviving the bloody Geonosis campaign, Rex continued his service to the Republic in the resultant Clone Wars against the Confederacy, during which he swore to defend all Republic citizens from harm. By 21 BBY, the second year of the war, the Mandalorian veterans who trained clone officers on Kamino had assigned Rex the battle honor of Mandalorian Jaig eyes, and he had the adornments emblazoned on his clone armor's helmet.

Rex's aggression earned him a reputation as one of the Republic's best soldiers as well as a standing as one of the toughest clones in the galaxy. He was promoted to the rank of clone captain and was given command of the Grand Army's famed 501st Legion, with which he was assigned to patrol the galaxy's feared Outer Rim Territories. After serving with Jedi Generals multiple times and bearing witness to their abilities, Rex came to be relied upon by the Republic's Jedi Generals during battles, and he was assigned to Jedi General Anakin Skywalker. As Skywalker's second-in-command, Rex learned much from his General and developed a certain friendship with him. He formed a working relationship with Denal and became close friends with Clone Commander CC-2224, nicknamed "Cody," after serving with him in several dangerous campaigns. Similarly, Rex befriended Advanced Recon Force Sergeant CS-2207, nicknamed "Boomer," following their close service in the war. Rex also became acquainted with Cody's own Jedi General, Obi-Wan Kenobi. At one point, Rex participated in a battle on the planet Tibrin alongside Cody and several Jedi, a dire campaign that the two clones managed to survive.

Battle of Christophsis
"Not good. We've got an energy shield. It's gonna make things damn near impossible. If you want experience, little one, it looks like you're about to get plenty."

- Rex, to Ahsoka Tano

In 21 BBY, Rex and Cody were dispatched with a Republic battle group under the command of Skywalker and Kenobi to liberate the planet Christophsis, which had been seized by the Confederacy. After the Republic forces had defeated the Confederate Admiral Trench's blockade of the world, Rex, prior to landing on Christophsis with his comrades, witnessed a broadcasted holotransmission alongside Kenobi, Skywalker, and Cody in which the Confederate General Whorm Loathsom, the leader of the Separatist invasion of Christophsis, ordered the planet's inhabitants to submit to Separatist rule. After establishing a base on the planet, the Republic forces moved to a business complex with two north and south-facing towers, from where they intended to intercept a group of Separatist battle droids when they reached the major plaza below the towers. Skywalker and Rex stationed their men in the North tower, while the South tower housed a detachment led by Kenobi, Cody, and Clone Sergeant Slick. As the droids approached the plaza, however, the enemy troop column suddenly split in half, and a squad of droids ambushed Kenobi's men in the South tower, compromising the Republic's plan. Once Skywalker had signaled clone pilot Hawk for an evacuation from the South tower, the Jedi, Rex, and their men used the grappling hooks of the clones' DC-15A blaster rifles to cross the gap between the towers.

The group avoided laser fire from the droids below and reached the adjacent building, arriving to reinforce Kenobi. Once the droids' advance had been temporarily impeded, the entire detachment took a turbolift to the roof of the tower. Pursued to the roof by T-series tactical droid TJ-55 and more enemy troops, Skywalker and Kenobi battled the droids while Rex, Cody, and the clones provided covering fire. Hawk's LAAT/i gunship soon arrived and hovered near the edge of the roof, and the Jedi and clones escaped with TJ-55's cranial unit, which trooper Gus had pilfered. Back at the Republic base's command center, Cody and Rex analyzed the droid, but it only revealed that the Confederacy had been aware of the Republic's plan before it stopped processing. When the clone officers reported their findings to their Jedi Generals, Skywalker suggested that a breach in security had allowed the Separatists to access their plan, but Kenobi went so far as to suspect that there was a spy among their men. The two Jedi decided to investigate behind enemy lines, ordering Rex and Cody to keep their mission confidential and apprehend the traitor.

Shortly after the Jedi had left, however, an alarmed Cody found an activated comlink on a nearby table, evidence that someone had been remotely eavesdropping on the entire conversation. Rex then noticed a figure in the hallway who was too far away to be recognized&mdash;Sergeant Slick, who had secretly become a spy for the Dark Acolyte Asajj Ventress and the Confederacy out of a grudge against the Jedi. Slick immediately broke into a run and ignored Rex's commands to stop, forcing Cody and Rex to pursue him through the base. Although the two officers lost their target, they were able to follow his trail to the mess hall because of the arrangement of the base's hallways. Entering the mess hall, Rex and Cody discovered that the only people there were their fellow clones, and they subsequently realized that one of their brethren was the traitor. Returning to the command center with Cody to continue their investigations, Rex used the astromech droid R2-D2 to check the base's records of external communications. Musing through the droid's findings with a datapad, Rex was able to trace an irregular wavelength to Slick's barracks, and the evidence led Rex and Cody to infer that a member of Slick's platoon was the spy. To this end, the clone officers decided to individually interrogate Slick's men and did so in the platoon's barracks despite protest from Slick. Though troopers Jester, Punch, Sketch, and Gus all passed the interrogations, the questioning forced trooper Chopper to reveal that he had broken war protocols by stealing droid fingers from the battlefield and making a necklace out of them.

Although Slick attempted to put Chopper's credibility into question, the Sergeant inadvertently revealed his knowledge of the Jedi's mission in the process&mdash;information that he would have only known if he had been listening on Rex's and Cody's earlier conversation with the Jedi through the discovered comlink. When put on the spot by Cody, Slick attacked him and Chopper and promptly fled from the barracks, leaving the other clones shocked with the revelation of Slick's true allegiances. Rex's and Cody's pursuit of Slick to the gunship landing platform yielded some unpleasant results in the form of several pre-planted thermal detonators, and the pair took cover just before the explosives were detonated; the landing platform and the weapons supply depot were compromised in the resulting explosion. Learning from Gus that Slick had been spotted running into the command center, Rex and Cody headed there to apprehend the spy. Once there, the duo noticed that Slick was hiding in the room's air ducts and engaged in a ploy to bait him out of his hiding place. While Cody secretly took the ammunition out of his DC-15S blaster and left the weapon on a communication hub, Rex appeared to leave for the south exit to get the generators restarted. Once the door had closed behind him, Rex re-entered the room and assisted Cody in confronting Slick, who had risen to the bait and forsook his cover to steal Cody's empty blaster. Although held at gunpoint by his commanding officers, Slick refused to surrender and grabbed Rex's blaster, bowling him over and aiming the weapon at him.

A brawl began between the clones when Cody and Slick disarmed and engaged each other in close combat. Rex joined Cody in fighting Slick but only received a blow to the head when he pulled the traitorous Sergeant away from Cody. After Slick knocked Rex to the ground and used the "groin popper" maneuver to dislocate his leg, Cody swiftly knocked Slick out, and the Separatist spy was locked in handcuffs. When Skywalker and Kenobi returned to the base, Rex and Cody presented them with the apprehended Slick. Having regained consciousness, Slick attempted to justify his actions, but he only received sharp retorts from his clone officers on his conflicting loyalty to his brothers and his role as a Separatist agent, the latter of which had put his brethren at risk. Once Slick had been taken away to lock-up, Rex and Cody reported the spy's sabotage of the weapons depot to Skywalker and Kenobi, who replied that they had discovered the full strength of the Separatists' main droid force, numbering close to a thousand. It was not long before General Whorm Loathsom launched his first assault on the Republic forces, which became based out of Crystal City.

After several days, the Jedi and clones were able to beat back the Separatists, and the droids retreated. Rex took advantage of the lapse in fighting to shave his hair and review casualty reports on his datapad near the Republic's temporarily established medical center. There, he conferred and joked with the medic on duty, Clone Sergeant Coric, and trooper Ged, who was being treated for a shoulder injury. The moment the Confederate forces launched another assault, Rex immediately grabbed his rifle, sprinted for the street without a backward glance, and joined Skywalker and Kenobi in defending the Republic's position. While Cody assisted Kenobi in leading the troops to defend the Republic's base, Skywalker, Rex, and a clone platoon proceeded through a route parallel to the main street and made their way behind the droid lines. Along the way, Rex recalled how just days before, Crystal City had been a landscape of glittering beauty before being crippled by the ongoing battle. Rex, Sergeant Coric, Ged&mdash;whom Rex noticed had been patched up for battle&mdash;and the rest of the men accompanied Skywalker to an energy sphere tower, where they divided their troops. While the majority of the troops was left at ground level to ambush the street-level droids, Rex took a small group of clones to accompany Skywalker to the roof to surprise a trio of advancing Separatist tri-droids from above.

The clones used JT-12 jetpacks to safely descend to the ground below, while Skywalker landed on one of the droids himself. The group's combined efforts brought the three droids down, and the clones proceeded to attack the droid lines marching through the street from behind. Once Loathsom and his army had been forced to retreat once more, a Republic Nu-class attack shuttle landed in City Plaza. Although Kenobi believed his new Padawan learner to be on board the ship, he and Skywalker soon found that the shuttle had not brought reinforcements&mdash;in place of the expected troops was the young Padawan Ahsoka Tano, who had been apprenticed to Skywalker. Rex was introduced to Tano at the observation post and was surprised to meet Skywalker's Padawan, as his Jedi General had previously stated that he would never take an apprentice. Rex could not help but chuckle when Tano nicknamed her new Master "Skyguy," but Skywalker, annoyed with Tano's arrogance and lack of respect for him, told his clone officer to give her an "acquaint of the position" and take her on his rounds to inspect all of the Republic's lookouts in the city. Rex complied and ushered Tano away to confer with her privately at the Republic's defensive positions. Using various elements of his training, Rex helped Tano to better understand her role in the army. He and Tano were eventually able to reach an understanding of each other&mdash;although Tano was still eager to prove that she was ready to be an apprentice, she learned to be less arrogant and more respectful to her superiors.

While walking with Rex near the Republic's AV-7 Antivehicle Cannons, Tano noticed that the Confederacy was deploying a deflector shield. Rex did not take the development lightly and grimly remarked that it would render the Republic's artillery useless. Returning to the Republic's comm station, Rex and Tano joined Skywalker and Kenobi in planning a defense of the base. It was decided that Skywalker would take his Padawan to infiltrate the droid lines and eliminate the shield generator, while Kenobi and Rex would draw the droids into the buildings to stall for time. After Skywalker and Tano had departed, Rex and Kenobi attempted to use the heavy cannons in defense but only confirmed that the artillery was indeed useless against the droids' shield. Using an unencrypted comlink channel to make the command appear more convincing to the Separatists, Rex ordered the clone forces to fall back before switching back to a secure channel. He then eavesdropped on the Confederacy's voice traffic and learned that Loathsom had ordered his forces to target the Republic's heavy cannons, which had prevented his troops from advancing earlier in the battle.

As soon as the deflector shield had passed over them, Kenobi led a charge on the battle droids' front lines, and Rex and his men lured the Separatists into the buildings. When the droids fired a missile at the comm post that Rex was using as cover, he was winded and knocked to the ground by the explosion. Rex was forced to order his men to retreat, and he met with Kenobi at the command center. Although Rex volunteered to fire the cannon at the droids inside of the shield, a risky action that would cause fatal overpressure, Kenobi instead ordered him to marshal his troops in a defense of the heavy cannons while the Jedi Master himself delayed the droids. Despite his reluctance to leave Kenobi to fend for himself, Rex complied and retreated while Kenobi fought the approaching droids. As the shield approached the heavy cannons, Rex, Coric, and their men countered the advancing droids' fire from some rubble near Crystal City's main street. Upon learning that Kenobi had surrendered to Loathsom, Rex deduced that the General was simply stalling for time and rallied his men to continue fighting. Skywalker and Tano soon destroyed the shield generator, and catching sight of the receding shield, Rex killed the Kerkoiden tank commander he was aiming at out of sheer relief. He ordered the heavy cannons to commence firing, and the Republic employed its renewed artillery usage to eradicate the battle droids.

With the battle over and reinforcements led by Admiral Wullf Yularen landing on Christophsis, Rex allowed himself to feel the deaths of his comrades personally. Although LAAT/i gunships arrived and began to bombard the nearby lines of battle droids, Rex helped Coric search through the debris for surviving troopers regardless of the danger posed by the incoming fire. Rex eventually departed to pick up Skywalker and Tano from the shield generator station aboard a gunship, retrieving the two Jedi and returning with them to the command base. During the flight back, Rex congratulated Skywalker and Tano on their successful mission.

Battle of Teth
"If we can't stop them, then we delay them as long as we can, and after that we make sure they have to crawl over our bodies. It's been an honor, gentlemen."

- Rex, to Torrent Company

Following the liberation of Christophsis, Skywalker and Commander Tano were assigned to rescue Rotta, the son of the Hutt crime lord Jabba Desilijic Tiure, from enemy kidnappers in order to win Jabba's favor to allow the Grand Army access to Hutt-controlled hyperspace lanes. Rex and Torrent Company, his 501st Legion detachment, accompanied the two Jedi to the planet Teth&mdash;where Republic scouts had tracked the Huttlet&mdash;in an Acclamator-class transport. Because the monastery where Rotta was being held was atop a cliff and was being guarded by a number of battle droids, Skywalker elected to launch a vertical assault up the cliff face to reach the monastery. The Republic forces were ferried to the surface in LAAT/i gunships, and LAAT carriers brought a pair of AT-TE walkers along as extra support. When the monastery's droid defenders opened fire on the approaching craft, Clone Lieutenant Hawk&mdash;the pilot of the gunship carrying Skywalker, Tano, Rex, and some of Torrent Company&mdash;closed the gunship's blast shields to deflect the incoming fire. The gunships landed in the forest below the cliff, and the AT-TEs returned fire at the droids, providing cover for the Jedi and clones to take refuge in an overhang. Rex soon sighted an object falling from the cliff, and though he initially believed it to be an explosive device, it was discovered to be a fallen battle droid, which he confirmed to not be booby-trapped.

Employing both vines and their blasters' ascension cables, Skywalker, Tano, Rex, and Torrent Company climbed up the cliff, and Rex himself fired his rappel line to ascend the face. As a vertical crossfire began, the battle droids' laser fire caused one of the AT-TE walkers to lose its grip on the cliff, and Rex watched in horror as the AT-TE plummeted to the ground, eradicating all of the troops beneath it. When B1 battle droids on Single Trooper Aerial Platforms flew in to attack the clones, Rex targeted his blaster fire at the flying droids before Skywalker eliminated the droid-piloted craft. Torrent Company was eventually able to defeat the droids and reach the monastery, albeit at the loss of half of its men. Upon arrival at the summit of the cliff, Rex called in a gunship to casevac the fifteen troopers that had been wounded in the fight, and he and Skywalker deduced from the monastery's heavy droid presence that the Huttlet was being held by the Separatists. Leaving several men to look after their injured troops, Skywalker, Tano, and Rex took troopers Coric, Lunn, Vaize, and Ayar to retrieve the Huttlet from the monastery.

Entering the dimly lit castle, the clone troopers activated their helmets' headlights for better vision. The group was greeted by a protocol droid, who claimed to be the monastery's caretaker and thanked them for liberating him from the battle droids. Learning from the droid that the Separatists had kept their prisoners on the detention level, Skywalker and Tano proceeded to the lower levels to rescue the Huttlet while Rex and his men stayed to guard the entrance. Rex later returned to the monastery courtyard and effectively secured the castle with his troops. As it neared midday, Rex learned from Skywalker that he and Tano had found the Huttlet, and Rex sent Sergeant Coric to help transport Rotta with a backpack. After Skywalker and Tano had returned with Rotta, they prepared to leave the planet with the Huttlet on a gunship that Rex was had on standby for them. However, Tano's discovery that the Huttlet was sick halted their preparations for an evacuation. While Skywalker and Tano were delivering a status report to Kenobi through R2-D2's hololink, two Confederate C-9979 landing crafts approached the monastery and deployed Vulture droid starfighters and ground troops. With the droids invading the monastery's courtyard, Tano returned to the stronghold with the Huttlet while Rex and Skywalker organized their forces to counter the incoming droids. After briefly conferring with Skywalker on the weak chances of getting Tano and Rotta safely off-planet, Rex dispatched Sergeants Coric and Hez and their squads to provide covering fire for the rest of the force.

The Republic's only remaining AT-TE walker was shot down, and Torrent Company began to take heavy losses. Rex eventually entered the monastery, and with the clones inside the stronghold, Skywalker ordered his Captain to shut the monastery door. Rex initially refused, as Skywalker would be left outside and forced to face the droids on his own, but at the Jedi General's continued orders, Rex complied and fired a blaster round at the controls. Skywalker used the Force to propel himself through the closing gap and into the entrance chamber, sealing himself inside the monastery with the rest of his men and preventing the battle droids from advancing any further. With three-quarters of their men dead, several wounded, and only three medic-trained troopers remaining, Tano convinced her Master that it was best to find medical attention for the sick Rotta. The two Jedi left with R2-D2 to escape the castle while Rex remained with Torrent Company to defend their position. The Separatist forces&mdash;under the command of Asajj Ventress&mdash;were soon able to break through the door's lock, allowing B1, B2, and DSD1 dwarf spider droids to enter the building. Due to the battle droids' sheer numbers, Torrent Company began to be overwhelmed and gradually took heavy losses to enemy fire. Rex watched as his men were eliminated one by one before being knocked to the ground.

Feigning death, Rex secretly contacted his surviving comrades through his troops' private frequency and discovered that only five of his men, including Sergeant Coric, remained. As Ventress entered the monastery antechamber and gave orders to an OOM command battle droid, Rex destroyed the droid with one of his blaster pistols and then targeted the Dark Acolyte herself. Ventress, however, immediately drew her double-bladed lightsabers and deflected the Captain's laser shots. She telekinetically pulled Rex's blaster out of his hand and Force-choked him, interrogating him on Skywalker's whereabouts. Trained in mental resistance, Rex kept repeating his name, rank, clone designation, and battle group to avoid succumbing to the Dark Acolyte's influence. Ventress finally gave up her interrogation, and after dropping the defiant Rex to the floor, she performed a mind trick on him, ordering him to contact Skywalker and ask for the Jedi's location. Resisting Ventress's mind influence, Rex commed Skywalker of his own accord, using a false voice and addressing him as "Anakin" instead of his usual "General Skywalker" to allude to the Dark Acolyte's presence.

Unaware of Rex's exploit, Ventress threw him aside and departed to personally confront Skywalker, leaving her battle droids to guard the remaining survivors of Torrent Company. Maintaining an unconscious, unmoving position to avoid attracting the droids' attention, Rex suspected that his ribs had been broken but nevertheless checked in with his men over the clones' private frequency, keeping them prepared to mount a last stand on the Separatists. Skywalker soon contacted Rex via comlink, and because Rex had forgotten to divert the device to his helmet, the battle droids overheard the device's beeping. As the droids converged on him, Rex destroyed several of the droids closest to him and stole a blaster from one of them. Moving as one, the other Torrent Company survivors&mdash;Coric, Nax, Zeer, CT-9932, Del, and Attie&mdash;sprang to their feet and attacked the Separatist droids as well, pilfering blasters for themselves. The clones and droids engaged each other in a crossfire, with the former group using the fallen AT-TE walker as cover. Rex took a painkiller from his belt medpac before briefly reporting the situation to Skywalker. Zeer eventually chose to plant explosives in an eviscerated super battle droid and detonated it once it had been sent back into the Confederate lines. The trap droid destroyed many of its comrades, but after a brief lull in the fighting that lasted only for a few minutes, the battle droids soon returned and continued to fight Rex and his men. The six troopers were able to bring down an advancing Vulture droid starfighter, using it as cover to engage the droids at a closer proximity.

As the battle droids demanded the clones' surrender, Obi-Wan Kenobi&mdash;who had arrived at Teth with reinforcements in the form of Commander Cody, the 212th Attack Battalion, and an armada led by Wullf Yularen&mdash;commenced an air assault on the droids. Kenobi jumped out of his Delta-7B starfighter to assist Rex and the few survivors of Torrent Company while several LAAT/i gunships deployed Cody and his men. Learning from Rex that Skywalker was most likely still inside the castle, Kenobi went into the monastery to find the Jedi General. Eventually, Skywalker&mdash;having found and commandeered the Twilight, an old spice freighter, with Tano and Rotta&mdash;contacted Rex, reluctantly telling him that they would be unable to give support, as returning Rotta to his father on Tatooine was still their priority. Rex understood the Jedi's position and replied that he and his men would be able to hold out on their own thanks to Kenobi's arrival before the connection was severed. With his comrades providing covering fire, Rex ran toward an approaching dwarf spider droid and planted a primed thermal detonator on it, jumping away in time to avoid the explosion that engulfed it. As they continued to force the battle droids back, Rex and the clones were joined once again by Kenobi, who had returned after dueling Ventress inside the monastery and forcing her to flee. Rex voiced his doubt to Kenobi that Skywalker and Tano would be able to make it to Tatooine in their dilapidated freighter, but Kenobi was confident that Skywalker's abilities would enable him to travel through hyperspace to Tatooine.

The Republic was eventually able to defeat the Confederate forces and secured a victory on Teth. Amidst the settling dust, Rex expressed his frustration with the poorly handled operation to Cody. Although Rex was still devastated with the loss of Torrent Company, Cody stated that the battle had not been in vain, as Skywalker and Tano had reached Tatooine with the Huttlet. Rex and Cody later accompanied Jedi Masters Yoda and Kenobi to Jabba's Palace on Tatooine to retrieve Skywalker and Tano, who had returned Rotta to his father and established a treaty with the Hutts to allow the Republic Grand Army safe passage through Hutt Space. Upon meeting with Rex, Skywalker and Tano wanted to hear all the details of the rest of the battle in terms of the clones that had won and paid the price for it. Despite his distress from the clones' losses, Rex agreed to recount the battle to them. Though Torrent Company was replenished with new troops, the defeat of the original unit stayed with Rex for a long time.

Redeployment
"Your troops are settled, Captain? And ready for the fray?''" "''Yes, sir. They've adjusted well, and will do you proud."

- Anakin Skywalker and Rex

Following the Battles of Christophsis and Teth, Skywalker, Tano, and Rex returned to the galactic capital of Coruscant. When word reached the Jedi High Council that the Confederate General Grievous was targeting the planet Bothawui, the home to the key Republic-affiliated Bothan Spynet, Skywalker was given command of his own battle group to defend the strategic world from the Confederacy. Kenobi, who had been injured in a terrorist bombing, was unable to participate in the mission, but knowing that Skywalker would want Rex and the 501st Legion for his strike force, Kenobi had Rex and his men put on standby. As Skywalker's fleet&mdash;comprised of the Venator-class Star Destroyers Resolute, Pioneer, and Dauntless&mdash;was being prepared for departure, Rex got his men settled on the Resolute, which Skywalker had taken as his flagship, and enjoyed a brief reunion with Skywalker and Tano, who were both pleased that the Captain had been assigned to their task force. Once all was ready, Skywalker's fleet left Coruscant for the Both system, to where they were pursued by Grievous and an armada of four Munificent-class star frigates. Although they managed to beat Grievous to Bothawui, Skywalker, Tano, and Rex soon learned from Kenobi that Grievous had not abandoned his pursuit of them; he had simply stopped to take on two extra frigates to overwhelm Republic forces on the planet Falleen.

Despite being outnumbered two-to-one in vessels, Skywalker was intent on protecting Bothawui and was unwilling to let it fall to the Separatists. Skywalker deployed Rex and a detachment of AT-TE walkers to the asteroid belt surrounding the gas giant Bothawui Prime, from where they would be able to outflank Grievous once his fleet had passed through the asteroids. After Grievous's six-frigate fleet arrived in the system, passed through the asteroid belt&mdash;as well as the AT-TEs hidden there&mdash;and opened fire on the Republic Star Destroyers, Rex and his men changed the tide of the battle by attacking the frigates and targeting their aft sections. The ambush was all the more successful because the unsuspecting Grievous had previously diverted all of his frigates' power to their forward shields instead of their rear ones. The Resolute, Pioneer, and Dauntless attacked the Separatist armada, but not before Grievous was able to flee his crumbling fleet in his personal starfighter, Soulless One. Skywalker was hampered in his pursuit of Grievous by damage to his Delta-7B starfighter, and the Jedi and his fighter veered toward the asteroid belt.

Rex was able to rescue Skywalker from his crippled ship, but could not save R2-D2, who had accompanied the Jedi General on his starfighter. Rex and Tano met with Skywalker in the Resolute medbay once he had regained consciousness and brought him up to date with the battle's success, albeit with the loss of R2-D2. After conducting an unsuccessful search for his astromech droid, Skywalker was forced to declare R2-D2 officially missing in action. Believing that the Resolute, Dauntless, and Pioneer could use modifications, Skywalker took his fleet back to the Allanteen Six shipyards where they had been manufactured. Eventually, Kenobi contacted Skywalker and Tano at the shipyards and tasked them with finding a new Confederate listening post &mdash;which, as Republic intelligence had just confirmed, had been intercepting the Grand Army's transmissions&mdash; before it could continue to pose a threat to the Republic's war operations. With this new assignment, Skywalker's fleet left the shipyards, and Skywalker elected to personally undertake the sweeps of space suspected of Confederate activity while the rest of his forces concentrated on a more central path. When informed by Skywalker of this decision, Rex questioned whether he was sure he wanted to scout ahead alone, but the General was certain that more than one fighter would attract too much attention from the Separatists. Taking the replacement astromech droid R3-S6 with him, Skywalker departed from the Resolute in his retrieved Delta-7B fighter, unaware that R3-S6 was a spy working for Grievous.

Not long after Skywalker had left, Tano received a signal from the homing beacon of her Master's fighter. Alarmed that her Master's position had been compromised, Tano had Rex gather as many men as he could to mount a rescue mission. Tano, Rex, and a squad of troopers arrived aboard the Twilight to reinforce Skywalker against a pair of Confederate Munificent-class frigates&mdash;led by Grievous himself&mdash;and a squadron of Vulture droids. As his hyperspace docking ring had been hit by enemy fire, Skywalker piloted his fighter into the Twilight cargo bay to retreat with the Republic squad. With Rex and his men providing covering fire as gunners, Tano maneuvered the Twilight right between the wings of the two enemy frigates, and as soon as the ship was clear, Rex engaged the Twilight hyperdrive, executing a successful escape from Grievous. A short while later, R2-D2, who had been captured by the scavenger Gha Nachkt, was able to get a message on his plight through to the Twilight. Rex tracked the astromech droid to Ruusan 2, a moon of the planet Ruusan. The Twilight arrived over the moon, where the group discovered Skytop Station, the listening post that the Republic had been looking for. Despite Kenobi's orders to sabotage the station without retrieving R2-D2, Skywalker resolved to mount a dual operation to save his captured astromech droid and destroy the base. Once the Twilight had entered the gassy atmosphere of the moon, Skywalker, Tano, Rex, and four other troopers used the Force and JT-12 jetpacks, respectively, to safely land on the station many meters below. On Tano's orders, Rex carried R3-S6 to the station, a job he was not particularly enthusiastic about undertaking because of the droid's substantial weight.

Upon landing with the heavy R3-S6 in his arms, Rex insisted that he would never lug an astromech droid around again. After entering the station with the others, Rex and another trooper quickly shot down two B1 battle droid guards in their path. They proceeded with the rest of their unit to a nearby computer terminal, from which R3-S6 accessed the station's building schematics and holographically relayed them to the squad. Rex briefed the squad on the location of the station's reactors, which, if destroyed, would cause Skytop Station to drop through Ruusan 2's atmosphere and be destroyed. Skywalker left the task of planting the explosives at the reactor room to Tano, Rex, and the clones while he himself went to find and rescue the captive R2-D2. Upon arrival at the reactor room thirty levels below, Rex and Tano noted that an alarm had triggered the ray shield of the entrance to the room and reported this to Skywalker. R3-S6 plugged into a nearby terminal and tried to bypass the shield, but as time passed and the squad heard battle droids approaching in the distance, Rex became doubtful of R3-S6's abilities and questioned them.

Although Tano admonished Rex, telling him to be patient, R3-S6 was actually stalling to give the approaching battle droids time to ambush the Republic squad. He was successful in this delay when a squad of B1 battle droids arrived and attacked the Jedi and clones. While Tano deflected laser shots with her lightsaber, Rex and his men used the hallway's supports as cover and opened fire on the battle droids. As the battle continued, R3-S6 activated the reactor room's secondary door, sealing the Jedi and clones off from the reactors. When the Padawan and the clones were caught in a crossfire with the arrival of B2 super battle droids, Tano had Rex utilize electro magnetic pulse grenades&mdash;nicknamed "droid poppers"&mdash;against their adversaries, and a grenade tossed in both directions effected the deactivation of the battle droids. However, the Republic squad's troubles were not over. Grievous himself arrived and confronted the squad, batting Tano aside and attacking Rex and the clone troopers. The five clones targeted their blaster fire at Grievous in defense, but the troopers were knocked aside, and all except Rex and trooper Denal were killed. As Grievous prepared to murder the unconscious Rex, Tano intervened in time to stop the cyborg's death blow with her own lightsaber. Tano continued to distract Grievous by drawing him into a storage room, and after regaining consciousness, Rex and Denal learned of Tano's exploits. Although Rex protested to her course of action over a comlink transmission, he complied with her orders to complete the mission. Rex and Denal were able to enter the reactor room and plant the explosives there, and the two then rendezvoused with Skywalker and the Twilight at the station's landing bay.

Skywalker was alarmed to learn from Rex that Tano had engaged Grievous alone. As Rex and Denal headed toward the hangar's exit to take Skywalker and the Twilight clone pilot back to assist Tano, R3-S6 closed the blast doors and sealed all of the hangar's exits, both to the rest of the station and out of the listening post. The astromech droid also activated several Vulture droids hanging from the roof, revealing his loyalties to Grievous and the Separatists. Surrounded by Vulture droids on one side and super battle droids on the other, Skywalker and the clones ran for cover behind several nearby crates while returning the droids' fire. As the firefight progressed, Skywalker ordered Rex to activate the explosives planted at the station's reactors, despite the fact that the entire squad was still in the station. The Clone Captain detonated the charges, crippling Skytop Station's reactors and beginning its gravity-pulled descent into Ruusan 2's atmosphere. After Skywalker sent R2-D2 to open the main hangar door from a terminal on the station's exterior, Tano joined the hangar fight and made her entrance by eliminating two of the Vulture droids. When Rex noticed several fuel cells next to the crates, Skywalker used the Force to hurtle one of them at the droids, and Rex placed a well-aimed shot on the cell. In the resulting explosion, all of the remaining droids were eliminated. R2-D2 was able to open the hangar door, and after the Jedi and clones had escaped the station aboard the Twilight, Skywalker retrieved his astromech droid, completing the successful operation.
 * UPDATE WITH JOURNEY THROUGH HYPERSPACE

Mission to JanFathal
"You don't mean to go on the mission, do you, Captain? It's not really your job. It's mine, in the absence of any embarked troops. And I've done extractions before. Except we'll do this one my way, and with any luck it won't turn out like Teth."

- Rex, to Gilad Pellaeon

Several months into the war, Rex agreed to relieve Skywalker of his Padawan for a few days by taking her along on a three-day shakedown cruise aboard Republic Navy Captain Gilad Pellaeon's newly refitted assault ship, Leveler, in the Dantus sector. After Pellaeon, whom he was acquainted with, permitted him to join Leveler testing session, Rex departed to join the cruise with Tano, Sergeant Coric, and six clone troopers new to Torrent Company&mdash;Ross, Boro, Joc, Hil, Vere, and Ince, who had completed their training just days earlier. En route to Leveler aboard a shuttle, Tano questioned if her Master had decided to take a respite from training just to take a break from her, but Rex abstained from directly answering the question to avoid speculating about Skywalker's actions. The Clone Captain was more concerned with his new 501st troopers, worrying that he would have to make use of the inconsiderate tally sensor to tell the six rookies apart because they had so far failed to display unique personalities. After arriving aboard Leveler, Rex exchanged a few warming, casual words with Pellaeon in a brief reunion with him. Once Tano had put on a uniform that Pellaeon had deemed more appropriate than her rather revealing choice of clothing, Rex and his men got settled on the ship. At Tano's request, Rex took her to examine Leveler experimental concussion missiles. Pellaeon found the two at one of the missile bays and discovered that Rex was sporting a new blue-striped hairstyle to support the Sullustan Bylluran Athletic team in the Bolo-ball final.

Rex and Pellaeon were cut off from a discussion on Leveler new weapons by an alert that a flotilla of Confederate ships had exited hyperspace in the nearby Fath sector. While Rex and Pellaeon monitored the scans and logs of the suspicious Separatist activity, Tano sensed a disturbance in the Force, which, at Rex's advice, Pellaeon took to heart. Despite the fact that the enemy activity could result in nothing, Rex took precautions and departed to round up his men in case they would be needed. Returning to Torrent Company's barracks, Rex came to regret his own novelty, undignified haircut at the sight of his men's normal black haircuts and resolved to shave his hair as soon as the opportunity presented itself. After Rex relayed the situation to Tano and the troopers, Job's inquiries into Pellaeon's private life sparked a debate between Tano and the rookie clones about the Jedi Code's forbidding of attachment, which Rex ended by putting his men on standby for enemy contact. Once Tano had departed to check out the ops room at his suggestion, Rex reproved his men for putting Tano on the spot but was nevertheless pleased that the six clones were settling in even better than he had expected.

In an effort to keep himself and his men occupied, Rex took them down to the hangar deck to undertake some deck circuits and familiarize themselves with the planets of the Fath system, where Leveler was headed to keep a closer watch on the Separatist armada there. In addition, Rex contacted Skywalker and informed him of Leveler diversion to the Fath system. Despite Rex's belief that the Jedi General's involvement in the matter was unnecessary, Skywalker set off to rendezvous with Leveler. After shaving his hair back to its normal baldness, Rex joined Tano and Pellaeon on the assault ship's bridge just as the warship became host to the Altisian Jedi sect. Jedi Master Djinn Altis, who spoke for the group of Jedi, requested permission to dock his freighter, Wookiee Gunner, to Leveler on the grounds of receiving a distress signal from a Republic agent on the nearby planet JanFathal. Republic Intelligence confirmed Altis's story and detailed the agent's capture during a Separatist-allied rebel uprising against the world's Regent leader. Pellaeon approved the rendezvous with Altis, and Rex promised his men for the imminent hostage extraction mission alongside the Altisian Jedi in the absence of embarked troops. The mission was complicated, however, with Intelligence's identification of Hallena Devis to be the captive operative, a close acquaintance of Pellaeon.

While Rex and his men were familiarizing themselves with JanFathal's capital city, Athar&mdash;where Devis was being held&mdash;via a holochart in Leveler meeting room, Master Altis, Callista Masana, and Geith Eris of the Jedi sect boarded Leveler and convened with Pellaeon, Tano, and the clones to formulate a plan for the operation. As Pellaeon briefed everyone on the mission at hand, Rex objected when Pellaeon implied that he intended to personally participate in the mission; the Clone Captain cited that it was his own responsibility and that of his men in the absence of embarked troops. While a plan to rescue Devis was formed, Rex noted that all they could hope for was a successful rescue and not a full-scale fight against the Separatists. Meanwhile, Eris and Masana expressed their desire to undertake the reconnaissance of Athar themselves, as the very production of clones for the Grand Army went against their beliefs. Despite the two Jedi's intentions to prevent the clones from participating in the mission, Masana and Eris complied with the clones' wishes when Rex and his comrades insisted that it was their job. With the plan in place, Pellaeon, Rex, the clones, and the four Jedi made their way down to the assault ship's hangar bay, where the replenishment shuttle that the team would be taking to JanFathal was being prepared. Conferring with Pellaeon, Rex refused to use civilian clothing for the mission, stating that he preferred armor advantages over stealth. He also comforted Pellaeon and was confident that his squad would be able to rescue Devis from her quandary.

Once the Sullustan sensor technician Benb had finished with outfitting the shuttle, the clones and four Jedi boarded the craft. Before embarking with the others, Rex told Pellaeon to keep a lookout for Skywalker, who was tracking the Clone Captain's secure link. When Leveler was in position to deploy the shuttle, Sergeant Coric piloted the craft out of the assault ship's hangar and headed for Athar. During the flight, Rex attempted to mediate Tano's reservations with the Altisian Jedi, whose controversial beliefs directly conflicted with the orthodox Jedi principles upon which she had been raised, but encountered trouble with diverting her attention away from them. Rex also checked in with his rookie troopers over their private circuit and took pity on the new 501st inductees, as nothing in their training on Kamino could have prepared them to face Jedi of this incongruity. After bypassing a Separatist landing craft, Coric took the shuttle to enter JanFathal's atmosphere and immediately headed for Athar. At Altis's direction, Coric dropped the shuttle to such a low range that Rex became concerned that the craft was going to have a head-on collision with a ground transport, but Coric was nevertheless able to safely land the shuttle. The group immediately disembarked and headed for a nearby building, where Altis and Ross worked with a recording remote to observe the surrounding Separatist deployments.

Rex, Tano, and Masana then reconnoitered the vicinity of the building where Devis was being held by the Separatist-backed rebels. Rex formed a plan for a standard hostage extraction, electing to first secure the building's exit and then deploy teams to the roof and entrance to simultaneously infiltrate the Republic Intelligence agent's prison. After the rest of the squad had joined them there, Rex sent Altis with Joc, Ince, and Ross to cover the exit while he himself led the others to scale the building's wall and enter the structure via the roof. Once Altis had distracted Devis's captors, the JanFathal rebels Merish Hath, Shil Kaval, and Varti, Rex and his men used explosives to open a hole in the roof and joined the Jedi in confronting the rebels. With Hath incapacitated, Rex aimed his blaster at Varti, who in turn held his own gun to the still-captive Devis's temple. Though Varti attempted to stall and bargain with him, Rex surprised everyone by unhesitatingly firing his own blaster, killing the man and freeing Devis. Ignoring his near-mindless kill, Rex used a vibroblade from his gauntlet to sever Devis's handcuffs and ushered her toward the exit, despite her attempt to retrieve her comlink from the badly wounded Kaval. After Devis had been moved to safety, the building began to crumble, and Altis, Rex, Vere, and Boro charged out of the structure. While Ince took Devis to Coric's shuttle, Rex joined the fight against the approaching army of battle droids.

In the ensuing battle, Vere was wounded beyond help, leaving Rex pained with the loss of a trooper whose active service had only lasted eight days. Although Boro attempted to revive the fallen Vere, Rex told him to continue fighting, as the rookie trooper's life was put in danger the more he spent trying to help Vere. Boro briefly objected, but he eventually complied and began to return the droids' fire. Launching grenades at the droid ranks with his rifle, Rex prepared to lay charges and sacrifice himself so that the others could escape, despite protests from both Tano and Boro. Before Rex could execute his plan, Altis, Masana, and Tano focused through the Force, toppling a nearby building onto the droids and blocking their adversaries' path with rubble. With the battle droids' advance temporarily halted, Rex contacted Coric and unexpectedly found that the Sergeant and his shuttle were landing nearby to extract his companions. Although Coric had disobeyed his orders to wait only for the agent and the Jedi, Rex was nevertheless grateful that he had instead decided to come back for the rest of the squad. Once all of the Jedi and clones were on board, Coric piloted the shuttle out of the area, just in time to escape the pursuing battle droids. En route to Leveler, Devis thanked Rex for his men's efforts, and although Rex accepted her gratitude, he avoided starting a conversation with her in order to reflect on the loss of Vere.

When Rex noticed that Ross, Boro, Joc, Hil, and Ince had opened up a private comlink frequency, he respected their privacy and avoided intruding on it, knowing that they had to have some time to discuss matters&mdash;including the painful loss of Vere&mdash;without his interference. Rex instead conveyed his congratulations to his men on the successful rescue, though he noted that JanFathal was lost to the Republic. Leveler, meanwhile, was attacked by the Separatist destroyer Reaper and was forced to flee to hyperspace before Coric's shuttle could dock to it, leaving the Jedi and clones to fend for themselves. With their main source of life support gone, Rex ordered Coric to deactivate all of the craft's nonessential systems, but the limited supply of oxygen could not be improved. Boro's calculation that they would only be able to make it halfway to the Kemla Yard shipyard, the closest Republic-allied location, before they ran out of oxygen did nothing to better the situation. Instead, the squad elected to return to Athar and mount a last stand against the Separatist army there. Shortly thereafter, Skywalker arrived in the system aboard the V-19 Torrent starfighter Echo-97, and Rex updated his Jedi General on the situation. The mixed squad of Altisian Jedi and Torrent Company rendezvoused with Skywalker in JanFathal's occupied capital, where Skywalker was introduced to the rookie clones and the Altisian Jedi. Skywalker's report that he had seen several of the Separatists' hyperdrive-equipped CR-20 troop carriers, which could be used to escape JanFathal, did much to lift the clones' spirits.

While Ince kept watch on the Separatist lines, Altis received word from his comrade Ash Jarvee that Leveler was returning to the system from a miscalculated hyperspace jump and relayed this information to the others. Skywalker then sent Masana, Rex, and the clone troopers to a road bridge above a nearby sports field while he and the other Jedi seized a CR-20. At that point, the clones would provide covering fire until the ship lifted off, and they would then embark the troop carrier. Once Masana, Rex, and the clones were in position, Skywalker, Tano, Altis, Eris, and Devis commandeered the enemy craft and proceeded to rescue the troopers. However, Ince was injured in battle with the droids and was treated by Hil. A Vulture droid soon approached and fired at some paving behind the group, but Masana diverted the falling debris with the Force and edged over to attend to Ince. Rex and Ross stayed to keep the droid starfighter occupied, buying time for Masana and the others to carry the injured Ince onto the hovering troop carrier. The Vulture droid landed and advanced upon the two clones in walking mode, and Ross got the droid's attention while Rex himself tangled its legs with his rappel line, pulling himself toward the droid. He hung on despite the droids' attempts to throw him off, and the droid subsequently became more and more entangled in the line.

Rex's and Ross's combined blaster fire took down the droid, and the two troopers escaped to the CR-20, which promptly made for Leveler. While Ince was stabilized, the battle-weary Rex manned the troop carrier's blaster cannons with Tano, and both of them defended the shuttle from the attacking Separatist armada. Once the CR-20 landed in one of Leveler hangars, Ince was immediately taken to the warship's medbay. With all evacuees aboard, Leveler escaped to hyperspace, heading to rendezvous with Wookiee Gunner at Kemla Yard and drop the Altisian Jedi off. During the flight, Rex, his men, and Devis joined Ince in the medbay, where Rex attempted to busy himself through the aggravating wait for developments in Ince's case. Ince's kidneys began to fail, and when the trooper finally died from blood loss, the furious, ashen-faced Rex stormed out of the medbay and took refuge in the mess hall. Tano found the upset Rex there and discussed the Altisian Jedi's views of the clone army with him, which came to challenge Rex's own beliefs as well as Tano's. Accepting that he and the rest of his clone brethren were making the best of a situation they had not chosen, Rex was finally able to find stability with his beliefs, though Tano herself found it difficult to solidify her own principles.

Infiltration of Gwori
"Still no word. We have to assume they're in trouble. I think it's time to alter Master Skywalker's orders.''" "Are you sure, sir?" "Rex, just like Master Skywalker, you will'' have to learn to trust me."

- Ahsoka Tano and Rex

Following several defeats at the hands of the massive Confederate Navy, the Jedi High Council decided to target the InterGalactic Banking Clan's Gwori shipyards, which manufactured ships for the Confederacy. Because the shipyards' exact location on the planet had not yet been determined, the mission to infiltrate Gwori and pinpoint the shipyards fell to Skywalker, Kenobi, and Rex. To counter the planet's defenses&mdash;namely, a Separatist droid-operated blockade and a radiation beam that eradicated all life forms entering the world&mdash;Skywalker devised a plan for a small strike force to be frozen in carbonite and infiltrate the planet. R2-D2, whose presence would not cause much suspicion, would then pilot a ship carrying the squad to Gwori before releasing the team from the carbonite, and after locating the shipyards, the squad would report back to Masters Plo Koon and Saesee Tiin, allowing them to eliminate the facility with a Republic squadron. After gathering at carbonite freezing plant CT-642 with the others, Rex expressed his concern that the squad might be susceptible to hibernation sickness, but Skywalker assured him that they would not be frozen long enough for it to take effect. The squad was encased in carbonite with the addition of Tano, who had been ordered by Skywalker not to participate in the mission but nevertheless manipulated Admiral Yularen to receive clearance to go to Gwori as well.

With all preparations complete, the strike team proceeded to Gwori aboard the freighter VX-391 with R2-D2 at the controls. When the blockade's battle droids discovered that the freighter was unregistered, R2-D2 was forced to release the task force and escape from the ship just before it was shot down. The astromech droid freed Tano from her carbonite slab, and she in turn released the rest of the squad. Once they had found the starship construction facility, Skywalker and Kenobi dispatched Tano, Rex, R2-D2, and two other clone troopers to contact Masters Koon and Tiin from a nearby communication tower. After breaking into the station with the others, Tano contacted Koon, Tiin, and Yularen, who were waiting in the Moskk system, with the shipyards' coordinates. Before the infiltration team's evacuation from the planet could be arranged, however, the transmission was cut off when the shipyards' Overseer, Juhm, contacted the station and discovered that the Jedi and clones were still alive despite the elimination of their freighter. Tano, Rex, R2-D2, and their squad managed to flee from the station just before Juhm remotely destroyed it, and Tano relayed the developments to Skywalker and Kenobi. While their superiors infiltrated the shipyards, Tano, Rex, and their team went to find cover on Gwori's plains, where they were attacked by a squad of jetpack-equipped B2-RP battle droids.

After escaping from the droids, the group took refuge in a cave that they soon found to be the current residence of a large lizard-like creature, which killed one of the clones before Tano could eliminate it. As time went by, the extended lack of communication from Skywalker and Kenobi led Tano to deduce that the pair was in trouble. Tano decided that it was time to "alter" Skywalker's orders of staying concealed, and though Rex voiced his doubt with disobeying their mandate, he left the cave with Tano and the other trooper. However, Juhm was waiting for them with a squad of B2 super battle droids and ambushed them, killing Rex's and Tano's clone companion. Presented with the choice of either surrendering or being immediately shot down, Tano and Rex decided to comply with Juhm's demands. The two were taken captive and ushered away, leaving R2-D2 back in the cave. As night fell, Juhm had Tano and Rex attached to electrically charged frames alongside Skywalker and Kenobi, who had been captured at the shipyards. Before departing, Juhm left a trio of IG-100 MagnaGuards to guard Rex and the Jedi from spiders as a means of ensuring that they survived as a reminder to the shipyards' slaves of his absolute superiority. Although the four were tortured and electrocuted in turn, Rex grudgingly expressed his gratitude for the MagnaGuards' protection from the spiders.

In an attempt to free themselves, the three Jedi used the Force to destroy the droids, and R2-D2 arrived and cut the Jedi and Rex from their frames before the spiders could attack them. Proceeding to the shipyards, the group convinced Juhm's slaves to liberate themselves from their servitude. At dawn, Skywalker, Tano, Kenobi, and Rex stole one of the shipyards' near-completed Munificent-class star frigates and escaped from the facility with the slaves just as Koon and Tiin arrived with a number of bombers from Hunter Squadron and began their attack on the site, dropping their munitions on the construction facility. Using the ship's tractor beam, Skywalker retrieved trooper Toomer, who was still encased in carbonite and had been left behind when his slab's controls had malfunctioned. The Jedi attempted to pilot the frigate through the Separatist blockade, but after the battle droids picked up the mass of life forms on the ship, they activated the radiation beam. The ship's passengers were saved when Koon and Tiin intervened and destroyed the scan gate projecting the beam. The two Jedi Masters hitched a ride on the vessel, as their hyperdrive booster rings had been destroyed, and the frigate left the Gwori system for Coruscant. Back on the galactic capital, the ex-slaves of the shipyards found employment with the Republic. Once Toomer had been freed from his carbonite, Rex reassured the disappointed trooper that there would be more fighting to come.

Outpost inspections
"All right, listen up. There's only one target of interest in this sector: Kamino. It's the closest thing we clones have to a home. Today we fight for more than the Republic. Today we fight for all our brothers back home. Understood?''" "''Sir, yes, sir!"

- Rex, to Echo, Fives, and Hevy

Later in the war's second year, Rex was once again stationed with Skywalker, Tano, and Admiral Yularen on board the Resolute when it was deployed to the Bith system during the emerging threat of a new Separatist superweapon. Following the Separatist weapon's assault on General Plo Koon's forces in the nearby Abregado system, the Resolute was reassigned to protect the Republic's supply convoys alongside Kenobi; his flagship, the Negotiator; and the rest of their fleet. After Skywalker divided the fleet to increase its defensive perimeter and went with Tano to scout ahead for enemy activity, Rex was present on the Resolute bridge with Yularen when Kenobi contacted them to check on their progress as well as Skywalker's whereabouts. Yularen reported that the convoys were on schedule and also informed Kenobi of Skywalker's orders. Skywalker and Tano eventually discovered that the Separatist superweapon was the Malevolence, a powerful ion cannon–equipped warship, and the Resolute was again reassigned, this time to join the Republic's attack on the Malevolence near the Kaliida Nebula, which succeeded in eradicating the battleship and ending its threat to the Republic. Rex and Commander Cody were soon assigned to inspect several small Republic bases and listening posts and took Rex's Nu-class attack shuttle, the Obex, to a tracking station in the Pastil system.

Arriving on Pastil, Rex and Cody began inspections of the outpost, and the former commented on the station's strange cleanliness. Trooper Stripe told the two clone officers that the station was maintained by an MSE-series droid nicknamed "Rodent," commenting that the droid had a glitch and spent hours cleaning the outpost. Recognizing the droid's characteristics as those of a spy droid, Rex called out a Code Aurek alert and ordered the base's troopers to track down Rodent. The rookie clones were unaware of Rex's suspicions and initially believed him to be crazy, but when Rex found the droid and blasted its body, the droid's wheels activated of their own accord and fled, a feature uncommon in regular MSE droids. The troopers eliminated three of the wheels, and though the fourth made for a grate, Stripe destroyed the last wheel with a thermal detonator; the resulting explosion caused a significant amount of damage to the hallway. Amused, Rex told the troops to clean the mess up before leaving with Cody. After Cody reported their successful inspection to Skywalker and Kenobi, who were aboard the Resolute, he and Rex proceeded to Rishi Station, a Republic outpost in the Outer Rim's Rishi system.

The two clone officers were unaware that the base had just been overrun by a force of Confederate BX-series droid commandos. When Cody contacted the station to inform the clones there of the incoming inspection team, a droid commando posing as a clone trooper answered the transmission. Hearing the "clone's" droid-like responses, Rex sensed that something was amiss, but he and Cody nevertheless continued to the moon where the outpost was located, with Cody placing Rex in charge of the inspection. Upon landing at the station, Rex took note of the base's absence of an on-duty deck officer, believing such an error to be sloppy. The two clones were greeted by a droid commando disguised in clone armor. When Rex caught sight of a droid attack flare launched by the survivors of the initial droid assault, he promptly shot the "trooper" who had greeted them in the head. At first, Cody was shocked with Rex's brazen behavior, but after Rex removed his victim's helmet, the disabled droid commando was revealed. More droid commandos then appeared from behind several surrounding crates and ambushed Rex and Cody, who exchanged fire with their opponents while using other crates as cover.

The droids tossed a series of thermal detonators at the Obex, and the two clones jumped off the platform to avoid the explosion, firing their blaster cables at the underside of the platform to control their descent. Believed to be dead by the droid commandos, Rex and Cody descended to the ground below, musing over the elimination of their only means of escape from the Rishi moon and recalling their similar situation on Tibrin. Rex and Cody then came across the three survivors of the droid assault&mdash;rookie troopers CT-782, CT-27-5555, and CT-21-0408, nicknamed "Hevy," "Fives," and "Echo" respectively&mdash;and Rex ordered them to take their sunbonnets off to verify that they were clones. After the three clones had done so, a Rishi eel appeared from one of the nearby crevices, and Rex impressed the rookies with his marksmanship by killing the eel with a single blaster shot to its eye. Once the clones had introduced themselves, Rex and Cody learned from Echo that their Sergeant had been killed in the initial attack. Dubbing Echo, Hevy, and Fives "shinies," a derogatory term for the troopers' spotless armor that had not yet seen action in battle, Rex placed a handprint of blood from the eel's carcass on Echo's armor to commemorate his valor. When Hevy expressed the rookies' desire to recover their post regardless of their inexperience, Rex stated that there was hope for them yet. Climbing up the canyon wall to Rishi Station, Rex and Cody offered the carbines of their own DC-15S blasters to the rookie troopers, and Rex devised a plan to gain access to the station.

With Cody, Hevy, Fives, and Echo waiting on the sides of the main entrance as backup, Rex posed as Commando Unit 26 in clone armor and mechanically walked toward the blast doors' surveillance systems, through which he conferred with Droid Units 07, 08, and 09, who were guarding the entrance. Rex maintained his cover by pretending to adjust his "vocabulator" and using an inert droid head as visual verification for the guards. Although Cody doubted that the tactic would work, the droids admitted Rex entry to the station, and he and the others immediately gunned down the guards. Taking point despite Hevy's request for permission to do so himself, Rex led the squad to attack the droids in the command center. He shot at several droid commandos manning the central computer before he was targeted by the commando droid captain himself from atop his perch on a higher level. Rex's elimination of the droid's blaster only caused the droid to instead draw a vibroblade and jump down to slash at him, but he quickly snapped the droid's neck with his bare hands. Though the clones were able to defeat all of the droid commandos, their victory was short-lived. The group of five discovered that a Separatist fleet&mdash;led by General Grievous&mdash;was passing over the moon and deduced that the droids had hot-wired the station's "all-clear" signal to prevent the Republic from learning of the Confederacy's impending invasion. A C-9979 troopship was then dispatched from the fleet, deploying battle droid reinforcements at the base to investigate the lack of response from the droid commandos.

As Cody noted the clones' slim chances of success against the incoming droids, Rex formulated a plan to destroy Rishi Station; despite the plan's lack of convention, the subsequent ceasing of the all-clear signal would alert the Republic to the imminent invasion. Echo contributed to the plan, offering that the base's supply of highly explosive liquid tibanna gas could be used to help eliminate the outpost. Before setting the operation into motion, Rex and Cody spoke with Echo, Fives, and Hevy to prepare them for the forthcoming battle in which they would be taking part. Stating that the Confederacy's target of interest could only be Kamino and citing its importance as the closest thing that the clones had to a home, Rex rallied the rookie troopers with the knowledge that they were fighting for more than the Republic&mdash;they were fighting to defend their home and all of their brethren back there. While Cody, Hevy, and Fives went to gain time by confronting the advance droid forces at the entrance, Rex and Echo ushered several PLNK-series power droids, more commonly known as "plunk droids," containing the liquid tibanna into the command center.

As the three plunk droids were wired together, Rex encountered problems with the detonator's remote handset. Hevy stayed to repair the remote, allowing Rex, Cody, Echo, and Fives to escape from the station through a grate that opened to an external maintenance pipe. Once outside with the others, Rex assumed that Hevy had fixed the remote and was right behind them, but when he told Hevy to detonate the explosives, he discovered that the trooper had not yet joined them. Rex contacted Hevy and ordered him to vacate the base, but Hevy stated that because of the remote's defectiveness, he would have to detonate the charges manually, ignoring Rex's protests. Although the four clones backtracked to help Hevy, the trooper sacrificed himself to destroy the base and warn the Republic of the Separatist invasion. Picking up the absence of the all-clear signal, the Republic fleet arrived and forced Grievous's ships out of the system. LAAT/i gunships were additionally deployed to the moon, and Rex, Cody, Fives, and Echo flagged them down and were taken to the Resolute to meet with Skywalker and Kenobi. In the Star Destroyer's hangar, the two Jedi Generals commended Echo and Fives for their service in the battle by awarding them medals, and also honored Hevy's sacrifice. Stating that they were no longer shinies, Rex, impressed by the troopers' efforts, inducted Hevy and Echo into the 501st Legion.

Defense of Kamino
"With all due respect, General, if someone comes to our home, they'd better be carrying a big blaster.''" "I concur with Captain Rex, sir. This is personal to us clones." "''We'll make sure Kamino is secure. Tell your troopers in the 501st they're going home."

- Rex, Cody, and Anakin Skywalker

Several months later, the Republic intercepted a transmission between General Grievous and Asajj Ventress, and Skywalker, Kenobi, Rex, and Cody examined the message aboard the Resolute. The group subsequently learned that the Confederacy was planning another invasion of Kamino, a prospect that both Rex and Cody considered to be quite personal to them. To notify Kamino of the impending threat and prepare a defense of the planet, Skywalker and Kenobi set course for Kamino, and Rex met with his troops from the 501st Legion&mdash;including Fives and Echo&mdash;in the Resolute hangar bay and informed them of their new mission. After being transferred to an Acclamator-class transport, the group landed at the Military Complex of Kamino's capital, Tipoca City, where Skywalker, Kenobi, Rex, and Cody met with Jedi General Shaak Ti and Prime Minister Lama Su and relayed the news of the Separatists' plan. It was not long before Grievous arrived at Kamino with a large fleet to challenge the Republic's naval fortifications of the planet. While Skywalker and Admiral Yularen oversaw the space battle against Grievous's flotilla, Rex joined Cody, Kenobi, Ti, and Su in Tipoca City's command center to monitor the Republic's defenses. As debris from some Separatist cruisers fell into Kamino's oceans, however, the space engagement proved to only be a diversionary assault when the remains of the ships turned out to be several disguised trident drills. Grievous and Ventress used the craft to land troops in Tipoca City and proceeded to beleaguer the city's vital cloning facilities.

While the droids began to overrun the Military Complex, Rex and Cody found Echo, Fives, and the maintenance clone 99 with several young clone cadets at the facility's barracks; the cadets had been separated from their group and had required the troopers' assistance to return to the barracks. Although the cadets did not believe that they could help to repel the Separatists, as their training had not yet been completed, Fives and Echo underlined the fact that it was their home that they were defending. With the droids about to reach the barracks, 99 took Rex and Cody to the nearby armory to retrieve weapons for the rest of the clones so that they could mount a defense of the barracks. The cadets hid in the raised retractable sleeping chambers along the wall of the barracks' main corridor to provide extra firepower at the right moment. When a battle droid squad led by Grievous broke into the barracks, Rex, Cody, Echo, and Fives immediately gunned down the advance forces at the entrance. They were unable to repulse all of the droids, however, and the clones were forced to retreat into the barracks, stampeding back along the main corridor with the droids in close pursuit. Rex, Cody, Fives, and Echo quickly took up cover positions behind several crates to return the approaching droids' fire.

As the B1 battle droid squad pushed Echo, Fives, and Cody back toward Rex's position, 99 tossed Rex a thermal detonator, which the Captain launched at the advancing droids. He missed, however, and instead hit an adjacent crate. Just after the droids had passed by the cadets' hiding places, Rex commed the young trainees to open fire on the droids, which they did to great effect. While the clones continued to gun down the surrounded droids, Cody used up the last of the thermal detonators. Although 99 opted to get more explosives from the armory, his decision to forsake his cover&mdash;despite Rex's and the others' protests&mdash;cost him his life, as he fell to droid fire. Cody shortly thereafter received word from Ti that the droids had been pushed back to the Military Complex's main hangar, and the Republic forces were eventually able to defeat the remaining droids, forcing Grievous and Ventress to retreat. However, the damage had been done, and Rex, Cody, Fives, and Echo all lamented the loss of 99, whom they believed, despite his debilitative cloning malformations, had been a true soldier. Rex and Cody later found Fives and Echo in the Military Complex's hangar and commended them on the true valor that they had shown in the battle. Once again impressed with their efforts, the two clone officers officially promoted the pair of 501st troopers, who had only been cadets not too long ago, to the illustrious rank of Advanced Recon Commando to serve on Kamino in the event of future Separatist attacks; Rex and Cody conveyed their sincere congratulations to Kamino's newest ARC troopers.

- Obi-Wan Kenobi and Rex, on Skywalker and Tano

While liberating the planet Queel from the Confederacy alongside Skywalker, Kenobi, and Tano, Rex accompanied the latter to eliminate the enemy's artillery encampment. Rex used a jetpack to cross the swamp to the artillery base, while Tano used a large dragon-like creature. Attacking the battle droids guarding the blaster cannons, the Padawan threw a blaster battery at the cannons with the Force, and Rex shot the flying target, detonating it and destroying the cannons. He then accompanied the Jedi back to the Republic's forward command post to take an incoming message from the Jedi Temple. In a conference with Jedi Masters Yoda and Ki-Adi-Mundi, Skywalker and Tano were assigned to intercept the Separatist agent Messo&mdash;who had stolen a Republic data file&mdash;in the Mon Gazza system, while Kenobi was to finish the battle on Queel. Rex and the two Jedi embarked on their new assignment aboard the Twilight, and upon arriving on Mon Gazza, Skywalker left to find Messo while Tano and Rex stayed to secure the freighter. Changing out of his usual armor, Rex donned a heavily covered-up disguise and accompanied Tano to find her Master, who had meanwhile located Messo. When Skywalker confronted his target in a podracing arena, however, he discovered that Messo had already transferred the data file, and the agent was killed in a collision with a podracer before he could reveal any more information.

Tano and Rex joined Skywalker in the stands to watch the race, where they learned that Skywalker had entered Tano into the race to get closer to the other racers, as he believed that Messo's contact belonged to one of the racing circuit's teams. The group proceeded to the podracing stalls to begin outfitting Tano's podracer, with Skywalker, Rex, and R2-D2 posing as the Padawan's pit crew. Tano's report that Jedi intelligence had confirmed several espionage incidents to have coincided with the racing circuit's presence in the same system&mdash;and that the skilled podracer Kidd Kareen and his crew had been present for each of the events&mdash;placed Kareen as the prime suspect for being Messo's correspondent. Once Kareen's crew had left, Tano kept Kareen occupied while Skywalker went to take a look around his stall, with Rex and R2-D2 on lookout. However, Maxus&mdash;a close friend of Kareen and one of his crew&mdash;caught Skywalker snooping around, and a fistfight began between the Jedi and Kareen's crew. Shortly after Rex joined the fray, Tano and Kareen returned, halting the fight, and Tano was forced to apologize for her crew's actions.

Tano, Skywalker, Rex, and R2-D2 hurriedly left to prepare when they learned that the Padawan's debut race was coming up. The race soon began, and Rex and Skywalker tracked Tano's progress through the course via R2-D2's hololink. As Tano approached the finish line, however, another podracer rammed her from behind, and Skywalker and Rex rushed to her aid. Although Tano's podracer had been demolished, Kareen offered to loan one of his spare podracers to Tano, who accepted the offer. Following the race, Skywalker and Rex trailed Maxus into a pub, and the two used R2-D2 to eavesdrop on the racer. Maxus's job as a Separatist spy was revealed when he contacted the Confederate Head of State Count Dooku, and the group also overheard Dooku's arrangements to have an agent collect the stolen Republic datachip from Maxus the following day. During Tano's second race alongside Kareen and Maxus that day, Skywalker and Rex took notice and immediately gave pursuit when Maxus stopped to pick up the datachip from the podracing pits. Though Maxus escaped in his podracer, he left the rest of Kareen's crew to engage Skywalker and Rex in blaster combat. While Rex and R2-D2 fought off the podracers, Skywalker departed to help his Padawan, and the Jedi were able to prevent Asajj Ventress from collecting the datachip from Maxus thanks to assistance from Kareen. With their mission a success, Skywalker, Tano, and Rex bid farewell to Kareen before leaving Mon Gazza aboard the Twilight. The trio then reported their operation's completion to Kenobi, who was still on Queel.

During an attack on Trade Federation forces over the Bothan colony world of Kothlis, Rex served as the gunner of Tano's BTL-B Y-wing starfighter. Each in their own starfighter, Skywalker, Kenobi, and Tano led the Republic fighters' attack on the Vulture droids that were deployed from a Federation Lucrehulk-class Droid Control Ship. Tano was able to reach the Droid Control Ship, which she assaulted with torpedoes, and Rex regarded the vessel's subsequent destruction as a beautiful sight. The Trade Federation Dreadnaught-class heavy cruisers were forced to flee, securing the Republic's victory over Kothlis. Shortly thereafter, Rex accompanied Kenobi, Skywalker, and Tano to the planet Taloraan, where the Jedi were to undertake negotiations for tibanna gas with the world's Denfrandi tribe. En route to Taloraan aboard the Resolute, Rex conferred with Tano on the prospect of the diplomacy that she would be engaging in within the next few days. Although Tano found diplomatic negotiations boring, Rex respected them as a different method of fighting. While the three Jedi left for the world's capital, Taloraan City, in a Nu-class shuttle, Rex remained on board the Resolute with Admiral Wullf Yularen to regularly check in with the Jedi. Unbeknownst to the Republic, however, Denfrandi Magister Orlin Denache had secretly allied himself with the Confederacy and was housing Separatist battle droids on Taloraan.

To contact the Jedi, the Resolute had to routinely leave orbit into a closer signal range. Eventually, during one of the regular trips into range, Yularen was warned by the Jedi, who had discovered the Separatist presence in Taloraan City, that the Resolute was heading into a trap&mdash;a Confederate Munificent-class frigate commanded by Captain Canteval was preparing to attack the cruiser. The Resolute activated its deflector shields just in time to deflect fire from the enemy frigate, and while the Resolute battled Canteval's ship, Yularen sent Rex and a clone detachment to rescue the Jedi, whose shuttle had been destroyed. After landing with several LAAT/i gunships at a platform in Taloraan City, Rex and his men fell under fire from the Separatist-allied Denfrandi, who had taken up positions behind some cargo boxes. The brief firefight was stopped when Denache's Republic-loyal emissary, Sech Govlinder, led the rest of the Denfrandi people to defeat the Separatists. The Jedi were able to establish a treaty with the Denfrandi and their rival tribe, the Wind Raiders, thanks to Tano's personal involvement in the matter&mdash;which had improved her views on diplomacy.

Enslavement
"Always figured I'd catch a blaster bolt in some combat zone, not live out my years on the end of a whip.''" "We'll get out of here eventually, Captain. My concern is what will be left of these people when we finally do. Anakin was right, you cannot truly know slavery until you've experienced it." "I guess it does change one forever. These poor souls have'' lost everything."

- Rex and Obi-Wan Kenobi, on the Togrutan population of Kiros

When the Confederacy invaded the pacifistic Togrutan colony of Kiros, Rex and a clone detachment were dispatched with Skywalker, Kenobi, and Tano to liberate the planet. In the world's capital, Rex accompanied Kenobi on a BARC speeder and attacked the battle droids with a machine gun, while Skywalker and Tano rode another speeder; Rex even used a rocket launcher to destroy several approaching Armored Assault Tanks. As the Republic secured the majority of the city, the Confederate Commander, Xerius Ugg, requested an audience with Kenobi, and the Jedi Master went to negotiate with their adversary, leaving his comlink open so that Skywalker, Tano, and Rex could listen in on the deliberations. The trio subsequently learned that Ugg had planted multiple thermal bombs around the city to force the Jedi to surrender. While Kenobi fought Ugg to stall for time, Skywalker and Tano went to disable the explosives and eliminate Ugg's bargaining chips. Rex assisted the Jedi when they came under fire from a sniper droideka at one of the bomb sites, using a sniper rifle to eliminate the droid. Although the Jedi were able to deactivate Ugg's explosives and defeat the Separatist Commander, they found that all of Kiros's Togrutan population had disappeared. Once Rex and the three Jedi had returned to the Republic fleet surrounding Kiros, Skywalker had his Captain recall the troops from the surface and prepare them for combat.

Following the battle on Kiros, Rex and a squad of troopers accompanied Skywalker, Tano, and Kenobi to investigate a lead on the Togrutas' disappearance concerning the Zygerria system, home of the Zygerrians, who had once been slavers before their slave trade had been largely decommissioned. The Republic squad took the Twilight to the remains of the Shi'kar species' homeworld to gather more information about the missing Togrutas. Amidst the asteroids, the group encountered the Zygerrian slaver vessel Fate's Hand. Pretending to be slavers themselves, Skywalker, Tano, and Kenobi boarded the Fate's Hand to gather what information they could from the ship's Captain, Onyx, while Rex and the troops hid behind several crates as backup. When the Jedi gave up the ruse and drew their lightsabers, Rex and the clones forsook their cover and began a firefight with the Zygerrians. As Skywalker led Tano, Rex, and several other clones to commandeer the Fate's Hand, more Zygerrians intercepted them and caught them in a crossfire. When a Zygerrian fired a rocket that damaged the seal between the Twilight and the Fate's Hand, Tano intentionally sealed herself on board the enemy ship, while Skywalker, Kenobi, and Rex were stuck on the Twilight with several trapped Zygerrians, who grudgingly surrendered.

A dismayed Rex reported Tano's actions to Skywalker and Kenobi, who deduced that she was simply attempting to infiltrate the ship by acting as a hostage. Rex secured the docking clamps of the Twilight to ensure that they would not be separated from the Zygerrian craft, despite being cut off from the ship. Attempting to force the Twilight away, Onyx took the Fate's Hand through the asteroid belt, and the Twilight bottom stabilizer was compromised from a collision with an asteroid. After Skywalker fired at and disabled the engines of the Fate's Hand, Tano contacted the Twilight, and at Kenobi's direction, she was able to unlock the Zygerrian ship's rear airlock before being discovered by Onyx. Rex and another trooper then accompanied Skywalker and Kenobi into space to board the Fate's Hand and rescue Tano, but they were soon stopped by a Blixus creature that Onyx had released. The blaster-impervious creature quickly killed the other clone and captured the two Jedi in its tentacles before Skywalker killed it, stopping its rampage. Rex boarded the Fate's Hand with Skywalker and Kenobi, and they surprised and confronted Onyx, who was forced to reveal his intelligence regarding the people of Kiros. Onyx stated that he had been invited to a grand slave auction on Zygerria, where the entire Togruta people were to be sold into slavery. On Kenobi's orders, Rex took Onyx to imprison him on the Twilight with his crew.

Once the Fate's Hand had been repaired, Skywalker, Kenobi, Tano, and Rex took the freighter to the Zygerria system in order to locate and rescue the missing Togrutas. Upon arrival at Zygerria, the Fate's Hand transmitted its permit codes to the battle droid blockade surrounding the planet and received clearance to land. Touching down on Zygerria, Kenobi and Rex donned disguises to avoid standing out, while Tano convinced Skywalker&mdash;who was masquerading as a slaver&mdash;to let her accompany him as his "slave merchandise" instead of Rex, whom Tano believed would not sell. After Skywalker and Tano encountered other slavers, Tano accidentally came close to compromising their cover stories, and Skywalker sent his Padawan back to the ship. Tano nevertheless joined Kenobi and Rex in serving as backup for Skywalker during his confrontation with several Zygerrian guards. When Skywalker was summoned to the Zygerrian Royal Palace to meet with the Zygerrian Queen Miraj Scintel, Rex, Kenobi, and Tano trailed Skywalker and his Zygerrian guard escorts to the Zygerrian Royal Palace.

After watching Skywalker enter the palace, the three went to investigate the catacombs beneath the building, and Rex took up a suit of Zygerrian guard armor and stunned a passing guard with his blaster. Rex and the Jedi then found Governor Roshti of Kiros, who had been imprisoned in one of the cells below the palace. After Tano freed Roshti, the group learned from the governor that the rest of the Kiros population had been taken elsewhere to be processed as slaves. When the palace guards discovered the intruders, Kenobi, Tano, and Rex escaped with Roshti on two reptile-like creatures, and Rex accompanied Tano on her mount, returning laser fire at the pursing guards. Presently, Skywalker contacted Tano and ordered her to go to the palace, as he required his "merchandise" to effectively present his cover story to Scintel. Although the four escapees split up, planning to meet back at the Fate's Hand, only Tano and Rex managed to return to the ship, while Kenobi and Roshti were captured by the Zygerrians. Tano dressed up and posed as Togrutan Princess Zaa Vashee, and with Rex acting as her "slavemaster," Skywalker was able to win Scintel's trust as well as an invitation to the auction at her side.

Rex put his Zygerrian armor back on and served as backup for Skywalker and Tano at the auction from a vantage point, but the three were met with a grim surprise when the captured Roshti and Kenobi were brought into the arena as slaves. As Scintel ordered Skywalker to whip Kenobi in order to prove his potential as a slaver, Skywalker signaled to Rex to ambush the Zygerrians. Swinging from a cable, Rex rained laser fire down on the Zygerrian guards in the arena, allowing Tano to retrieve her and the other Jedi's lightsabers and return Skywalker's and Kenobi's weapons to them. Rex joined Skywalker and Kenobi in the arena below and fought off the approaching guards, but the Captain was soon knocked unconscious by a rocket fired by a Zygerrian. The three Jedi were also subdued, and while Tano was imprisoned outside the Royal Palace, Kenobi and Rex were sent with Roshti to the Zygerrian Labor Processing Hub, suspended over a volcano on the planet Kadavo. Scintel, meanwhile, forced Skywalker to be her personal bodyguard, and his captured comrades served as the Queen's leverage over him. On Kadavo, Kenobi and Rex were "educated" in the ways of slavery alongside the enslaved Togruta population of Kiros. Both Kenobi and Rex remained intransigent to submitting to slavery, albeit at a high cost&mdash;the Zygerrians put to torture whenever Kenobi refused to submit to the slavers.

While working at an atmosphere-filtration turbine station alongside the Togrutas, Kenobi and Rex conversed on the fact that the colonists had lost most everything valuable to them, including their freedom. However, Rex helped Kenobi to rally the Kiros population with the news that their homeworld had been liberated from the Confederacy&mdash;if they were freed, they had somewhere to live. Recognizing the slaves' new submission to his slavers as hope, the Keeper of the processing hub had Kenobi and Rex brought to the facility's command center. The Keeper attempted to contact Queen Scintel for permission to eradicate Kenobi for his growing threat to the Zygerrians' slave production but did not receive a response, as Count Dooku had assassinated Scintel on Zygerria for her continued refusal to kill the Jedi. Having freed themselves from their servitude to Scintel, Skywalker and Tano arrived on Kadavo with a clone strike force to rescue Kenobi, Rex, and the Togrutas from the Zygerrians. As Skywalker and Tano began to cut through the facility's blast doors, the Keeper used the still-captive Togrutas as his leverage against the Jedi, exposing the entire population to the volcano. With the arrival of Separatist aerial forces led by General Grievous and Commander Asajj Ventress, Skywalker and Tano were forced to cease cutting through the door, and the Keeper took the opportunity to order them to surrender.

Instead of aiding the Zygerrians, however, the Vulture droid starfighters began to attack the facility's supports&mdash;Dooku was aiming to hide his involvement in the slavery affair by eliminating the Togrutan population. Taking advantage of the Keeper's distraction, Kenobi and Rex attacked the Zygerrians and joined Skywalker and Tano in rescuing the Togrutas from falling into the volcano. While the Confederate fleet retreated, the Jedi used the Force from atop Skywalker's stolen freighter to pull the Togrutas aboard the ship. Although Ventress assaulted the freighter with her ship, the Trident, Rex fired a rocket at the enemy craft, and the arrival of Plo Koon and a squadron of V-19 Torrent starfighters forced Ventress to retreat. After winning the battle, evacuating the facility, and taking the Keeper into custody, the Jedi and clones prepared to take the Togrutas home. As Rex was about to detonate charges planted in the processing hub, however, Supreme Chancellor Palpatine contacted the Jedi, ordering the facility to be left intact for future Republic use. As the Jedi could see no use of maintaining the facility, Rex proceeded with eradicating it. Upon returning to Kiros, the Togrutas forsook their pacifist ways to be able to defend themselves in combat, and Rex was among the clones who educated them in blaster combat.

- Ahsoka Tano, to Rex, during the battle at Vanqor

As the war continued, Rex participated in a battle on a planet against anti-Republic forces with Skywalker and Tano. During the engagement, Rex oversaw the operation of the Republic's AV-7 Antivehicle Cannons and had them return the enemy's bombardment. When Skywalker and Kenobi infiltrated Count Dooku's Munificent-class star frigate over Vanqor in an attempt to capture the Sith Lord, Rex took Wullf Yularen's place of commanding the Resolute&mdash;as the Admiral was recovering from the previous run-in with the Malevolence &mdash;and served aboard the Star Destroyer with Tano. Once Skywalker and Kenobi were aboard Dooku's frigate, the Resolute moved into position and opened fire on the Separatist vessel, but Dooku managed to escape in his solar sailer. Telling Rex and Tano to follow them in whatever ships were available, Skywalker and Kenobi gave pursuit in a stolen Sheathipede-class shuttle, but though they crash-landed on Vanqor alongside Dooku, it was a band of pirates that took the Sith Lord to their base on Florrum and imprisoned him there for ransom. After Tano had rescued Skywalker and Kenobi, Rex was present with the Jedi aboard the Resolute when the two Jedi Generals were sent by the Jedi Council to verify that Dooku was in the pirates' captivity so that the Republic could pay the pirates' ransom and take him into custody. However, Skywalker and Kenobi were unable to secure Dooku's apprehension.

During the course of the war, Rex became involved with sending Denal on various missions regarding a new Separatist threat. While Denal was participating in an investigation on the planet Rodia concerning a Confederate project somewhere in the Outer Rim, Rex contacted him and ordered him to make way for Republic reinforcements to land on Rodia by destroying the battle droids in a nearby jungle clearing. Once Denal had completed his objective and enabled the Republic to land additional forces, Rex again made contact with him and sent him to destroy an enemy transport factory on Rodia by activating the facility's self-destruct mechanism. Following Denal's success, Rex next dispatched him to Tatooine to scout out a seemingly deserted Separatist base there. After Denal had cleared the base of hostiles, Rex relayed the news that the Republic had discovered another Separatist base, this time a research station, elsewhere in the planet's deserts. As the enemy facility was reportedly connected to the new Separatist project and was already in the process of evacuation, Rex ordered Denal to act quickly before the Confederacy could destroy the evidence of the project. Infiltrating the station, Denal uncovered plans for a Confederate superweapon that was capable of concealing entire armies from the Republic, and he later destroyed the superweapon at its construction base on the ice world Orto Plutonia. Shortly after Denal returned to the Republic fleet and was commended by Obi-Wan Kenobi for his success, Rex sent Denal on yet another mission.

Rex himself was dispatched with Skywalker and Tano to the planet Taronda to secure raw materials desperately needed by the Republic, but the Separatists were also interested in Taronda's resources and attacked a mining settlement on the world to divert the Republic's attention. With Vulture droid starfighters attacking them from above, Skywalker had Rex gather the settlement's miners and prepare the encampment's deflector shield. Although Tano accidentally fell down a crevice leading to a mineshaft, Rex pointed out a bigger problem to Skywalker: the arrival of a major Separatist assault force composed of a C-9979 troopship, Multi-Troop Transports, and multiple Armored Assault Tanks. Once Rex had gotten the wounded miners and civilians to safety, he triggered the shield, protecting the settlement from the advancing droids, and also signaled for Republic reinforcements. When Asajj Ventress appeared just beyond the shield and baited Skywalker to confront her by stating that she had sent spider droids after Tano, Rex told Skywalker to focus and have faith in his Padawan and the lessons he had taught her, and he continued to restrain Skywalker when Ventress persisted with her taunts of his "cowardice." Ventress finally relented her pursuits when she discovered that a Republic Star Destroyer was inbound to Taronda, and she retreated from the planet with her droid forces. With the Separatists gone, Rex deemed it safe to disable the deflector shield, and he and Skywalker were soon rejoined by Tano, who had indeed been able to fend off the droids on her own.

When the malfunctioning merchant starship Deyvus sent out a distress call to the Republic that it was on an unpreventable course toward an unstable nebula, Skywalker, Tano, and Rex were sent aboard the Twilight to rescue the craft, as their ship was the nearest and fastest one available. Approaching the Deyvus on the Twilight, Rex noted that the damage to the merchant vessel appeared to be bad, with its ion drive apparently gone critical and its stabilizers offline. As the Twilight neared the craft and prepared to dispatch R2-D2 to access the ship's maintenance systems, the Deyvus suddenly revealed several battle droid–manned laser cannons&mdash;it was a trap that had been set by the Separatists. Before it could maneuver away, the Twilight was hit by the droids' fire and received engine damage, and Rex immediately used a fire extinguisher to put out the flames in the ship's cockpit. He informed Skywalker that another impact would cripple the Twilight, as its hull would not last. While the freighter began to be pulled toward the collapsing nebula, General Grievous holographically contacted the Jedi and lured them aboard the Deyvus, from where he claimed to be preparing to watch them die. Rising to the bait, Skywalker had R2-D2 begin repairing the Twilight engines and took Rex with him to the Deyvus to confront and capture Grievous. Using a pair of grappling hooks, Skywalker and Rex pulled themselves toward the enemy craft through the void of space. Along the way, Rex questioned the boldness of their plan, to which Skywalker replied that it was boldness that separated them from the Separatists in the war. Skywalker and Rex boarded the Deyvus and made their way from its gun deck to the bridge, cutting through the B1 battle droids and droidekas in their path. As the droids began to overwhelm them in one of the ship's hallways, Skywalker sliced a hole in an adjacent wall with his lightsaber, and he and Rex took their detour to the bridge.

On the bridge, Skywalker and Rex discovered that Grievous was not aboard the Deyvus; instead, the two were greeted by a large number of primed thermal detonators that were about to go off. Skywalker quickly cut an "X" in the cockpit's roof with his lightsaber, and Rex blasted a hole through the weakened metal, allowing the pair to return to the Twilight moments before the Deyvus exploded. Though the pair had not captured Grievous, they had foiled his trap for them. Eventually, Rex returned to Christophsis with Republic Senator Padmé Amidala; her protocol droid, C-3PO; and R2-D2 to investigate some intelligence leads that had been provided to the Jedi Order by the Nightsister Ros Lai&mdash;who had betrayed her Separatist-allied associates&mdash;regarding an alliance between the Nightsisters and the Confederacy. Once Amidala had confirmed that the Separatists were mining for something on the planet, her ship was shot down over Christophsis. Rex was injured in the crash and was imprisoned with Amidala and the droids in the Separatist base. While there, the group overheard the guards saying that the Confederacy was harvesting crystals from the planet core, which were to be used to power the newly constructed Separatist warship Devastation. The captives were freed by a Jedi team of two that had been sent to Christophsis with Clone Commander CC-1004, nicknamed "Gree," to rescue the Senator. While R2-D2 and C-3PO stayed at the base to assist the Jedi in their continuing investigation, Amidala helped Rex to Gree's LAAT/i gunship, which had a medical console on standby for him.

Detour from the battlefield
"You know, I can't figure those villagers not wanting to fight. No pride, I guess."

- Rex, on the Lurmen pacifists of Maridun

While stationed aboard the Resolute, Rex accompanied Skywalker, Tano, and Yularen to aid Jedi General Aayla Secura, whose fleet was being ambushed in the Quell system by Confederate forces. By the time the Resolute arrived over Quell, two of Secura's Star Destroyers had been decimated by several Munificent-class frigates, with only Secura's command ship, the Liberty, maintaining altitude. As jetpack-equipped B2-RP battle droids were launched from the Separatist fleet to board Secura's cruiser, the Resolute moved into position, and Skywalker, Tano, and Rex took several LAAT/i gunships with clones from the 501st Legion to cut through the droids and evacuate the troops aboard the Liberty. After Skywalker went ahead of the others to the crippled cruiser, a B2-RP battle droid attacked the gunship carrying Rex and Tano, who pulled the craft's clone pilot to safety in the gunship's troop bay after he was forced out of the cockpit by the battle droid. With its controls sabotaged by the droid, the LAAT/i gunship plummeted uncontrollably toward Secura's Star Destroyer. As soon as their vessel crashed into the Liberty hull, Tano, Rex, and their squad jumped out of the burning transport without pause and ran through the ship's corridors, destroying all of the droids in their path.

Rex and Tano caught up with Skywalker, Secura, and Clone Commander CC-5052, nicknamed "Bly," in the cruiser's hallways and joined them in continuing to cut through the opposing droids. The group headed to escape the crippled Liberty from a Consular-class cruiser that Skywalker had called in and was docking in the lower hangar. As the gangway to the frigate was extended, however, the Confederate fleet's increasing fire caused an inferno to rage through the Liberty. Sacrificing himself, Skywalker Force-pushed the others into the airlock, sealing the blast doors shut in both directions, and used the Force to hold back the approaching flames. Despite his efforts, the inferno finally blasted through the adjacent doors, and he was thrown against the airlock. Once Tano and Secura had saved Skywalker and brought him onto the Consular-class frigate, the Republic cruiser detached from the Liberty and headed for the Resolute. As the frigate began to dock to the Resolute, a Vulture droid attack inadvertently activated the frigate's hyperdrive. Although the Resolute was able to maneuver away in time, the Republic frigate jumped to hyperspace with the Jedi, clone officers, and other troop evacuees aboard. While Skywalker was treated in the frigate's medbay, more unpleasant news took the form of Bly's discover that the navigation computer's incorrectly inputted coordinates were heading the craft straight for a star.

Meeting on the bridge with Rex and Bly, Secura and Tano decided to shut down all primary power units to disengage the ship's hyperdrive so that their unintended destination could be avoided. With Tano at the controls, the frigate's power was deactivated, and the ship was brought out of hyperspace. Because of the vessel's uncontrollable speed and the lack of artificial gravity, Rex lost his grip on the back of Tano's seat and was smashed against Secura, causing her to lose her hold on the power switch. Secura telekinetically reactivated the switch, and with artificial gravity back on, she and Rex landed on the floor. Although Tano was able to maneuver the craft in time to avoid the star, she could not stop the ship from heading straight for the nearby planet Maridun. The frigate suffered damage while entering the planet's atmosphere before finally crash-landing on the planet. Rex, Bly, and the clones escaped the frigate first, and Rex helped another trooper out of the craft while Tano and Secura jumped out with Skywalker just before the ship exploded. After a makeshift shelter had been erected for Skywalker from the frigate's wreckage, Secura, Tano, and Bly took their only troopers&mdash;Cameron, Lucky, and Flash&mdash;to find help for the injured Skywalker while Rex stayed to watch over him. Before Tano left with the others, Rex assured her that he would take good care of her wounded Master and also wished her luck on her mission.

As night fell, Rex diligently guarded Skywalker. When Skywalker finally awoke and attempted to get up, Rex quickly ran over to his Jedi General and checked on his condition. However, a carnivorous mastiff phalone predator that had been watching the two for hours attacked Rex, pinning him down and trapping his blaster hand under one of its claws. Rex managed to fire a shot, startling the creature and scaring it away, and he aimed several final laser shots at its retreating form. Skywalker went back to sleep and did not reawaken until the next day. When he did, Rex insisted that Skywalker maintain his rest, but Skywalker told him that he could hear the sound of returning mastiff phalones. The two drew their weapons in time to greet the arrival of two more of the creatures. Rex gunned one of them down, but the other charged at the makeshift shelter and ripped it apart, knocking both him and Skywalker aside. At that moment, Tano and Bly returned with Wag Too, a healer from the planet's Lurmen colony. Too wrapped a rope around the feet of the remaining mastiff phalone, and Tano assisted Too in tugging at the rope to pull the creature to the ground. Despite an injured arm, Rex used his other arm to help the two. Once the mastiff phalone had fallen to the ground, Too secured the rope around the beast's legs.

With the mastiff phalone defeated, Rex followed Tano, Bly, and Too back to the Lurmen village, with Skywalker in tow on a stretcher that had been made from the remains of his shelter, While Skywalker was being treated by the Lurmen, Rex kept watch on the settlement's outskirts. During his tenure, he noticed the arrival of a Confederate troopship and reported this development to Bly, who was back at the colony with the Jedi. Bly told Rex to return to the village, and Rex joined the others in the seedpod hut where Skywalker was being administered to. To ensure that the Lurmen did not suffer as a consequence of their presence, the Jedi and clones decided to hide from the Separatists and leave the village on its own. Accompanying Tano and Secura, Rex and Bly assisted Skywalker to a nearby field of tall grasses behind the settlement. While there, Rex and Tano discussed the Lurmen's pacifism and denounced the colonists as shameful and cowardly until Secura intervened and asserted that it took courage to follow one's beliefs. When Skywalker suggested that they pilfer a shuttle from the Confederacy to escape from the planet, Rex agreed with his Jedi General, eager to steal from the Separatists. However, Tano suddenly noticed that a Separatist recon droid was spying on them. Though she and the two clones pursued the droid, it was Secura who destroyed it by working her way in front of it and surprising it.

From a nearby tree, the Jedi and clones discovered the Separatists' base and watched as General Lok Durd deployed his forces outside the base for a test run of his defoliator cannon, a weapon that was capable of specifically destroying living, not mechanical, targets. As Bly and Rex went to get a closer look at the new weapon, Durd sent two B1 battle droids&mdash;inadvertently, in the direction of the approaching clones&mdash;to serve as the weapon's test subjects. When a defoliator capsule was fired and birthed an expanding wave of fire that began to decimate all life in the area, Rex and Bly immediately fled for higher ground and fired their blasters' grappling hooks at the tree. Rex made it to safety, and though Bly tripped and misfired his cable, he was saved by Secura, who swung down on a vine and pulled him to refuge. The carnage that remained of the foliage in the vicinity was augmented by the fact that the two droid testees had not been damaged by the weapon. The Jedi and clones watched as Durd departed with an armament of troops, and Skywalker deduced that Durd intended to test the defoliator on the Lurmen village. Resolving to return and save the Lurmen, the Jedi and clones waited until night had fallen to ambush the droids guarding the Separatist base. Once Skywalker and the clones had cut down the droid guards stationed outside the facility, Tano and Secura opened the door, enabling the others to infiltrate the base. Using various crates as cover, Skywalker, Rex, and Bly eventually made it to the base's communication center and eliminated the droids manning the base.

Noticing a pair of shield generators, Rex and Bly brought them onto the Jedi's stolen Sheathipede-class shuttle and accompanied the Jedi back to the Lurmen colony. After daybreak, the Jedi and clones arrived at the village to be greeted by the village's chieftain, Tee Watt Kaa, who did not appreciate the return of the beings whom he viewed had brought the war to Maridun. Rex soon caught sight of the inbound droids from the village's perimeter, and despite Kaa's protests, Skywalker, Secura, Tano, Bly, and Rex formed a seedpod barrier to protect the colony from the imminent battle by working in teams to move several pods in front of the village. Once Bly and Tano had moved the shield generators into place, Rex noted that Durd's battle droids were holding position, and Skywalker stated his belief that the droids would attempt to hit the village with their long-range artillery before mounting a charge. Sure enough, the Separatists fired a defoliator shell, and Rex jumped off the seedpod barrier to stand with the others. Despite the extensive range that the defoliator covered, the pilfered shield proved successful in blocking the weapon's fiery wave of destruction.

Unable to attack the village from afar with the shield intact, Durd dispatched his first squad toward the village. The Jedi and clones walked through the shield and took up positions on the other side to repel the oncoming droids. While Skywalker, Tano, and Secura charged at the droids, Rex and Bly provided covering fire with their DC-15A blaster rifles. Although the group was able to defeat the first wave of battle droids, the second droid wave&mdash;comprised of Durd's second and third squads&mdash;soon launched an assault of their own. With an advantage in numbers, some of the droids slipped past the Jedi, forcing Bly and Rex back behind the pod barrier. Despite the clones' efforts, the droids breached both the deflector shield and the pod wall and marched into the village, destroying the shield generators. Secura and Tano joined the clones in defending the colony, while Skywalker disabled the defoliator and captured Durd. Aided by Too and several other Lurmen who sacrificed their pacifist upbringings to defend their colony, the Jedi and clones were able to save the village from being eradicated by the droids. With the battle over, Rex and Bly ushered the captured Durd and his Aqualish aide, Pune Zignat, into the Sheathipede-class shuttle. As the Jedi and clones prepared to leave Maridun with the thanks of the Lurmen, Admiral Yularen arrived with a fleet of Star Destroyers over the planet, having finally found the Jedi.

Bloodshed at Kothlis
"It's no use. Whatever bright idea they cooked up to fix the comm problem doesn't seem to be working. At least not yet. We're on our own, Ahsoka.''" "I'm going to find Master Kenobi. And another gunship. I'm getting you out of here Rex. Do you hear me?" "''Yes, ma'am."

- Rex and Ahsoka Tano, shortly before the former looses his balance as a result of his injuries

In 21 BBY, at some point following the Maridun engagement earlier that year, Rex and Torrent Company were transferred with Skywalker, Kenobi, Tano, and Yularen to the recently christened Star Destroyer Indomitable so that the Resolute could undergo a refit. Presently, the Jedi and their fleet&mdash;comprised of the cruisers Indomitable, Pioneer, and Coruscant Sky&mdash;received intelligence from the Grand Army's Special Operations Brigade that General Grievous was planning on seizing the planet Kothlis and its Bothan spynet facility. While in Indomitable mess hall, Rex, Sergeant Coric, and trooper Checkers were joined by Tano, who reported that the Special Operations Brigade's findings had been confirmed and that the fleet was heading to mount a defense of Kothlis. Rex learned from Tano that a ground assault on the planet was highly possible; if the Separatists had already begun to invade Kothlis, the counterattack on the surface would be led by herself and Kenobi while Skywalker commanded the space battle. The Captain then put his men on standby and had them begin preparations for the imminent battle. When Indomitable, Pioneer, and Coruscant Sky arrived at Kothlis, however, they found that Grievous had already arrived and had begun to beleaguer the undefended planet. The Jedi additionally discovered that Grievous was employing new technology to jam all of the Republic's comm channels.

Skywalker met with Rex, Tano, and their waiting men in their barracks and relayed the news of the Separatists' comm jammer to his Padawan and Captain. Although the unsettled Rex reacted to this development with concern, Skywalker asserted the possibility that regular comms would be restored in time and that reinforcements could be requested if necessary. Before proceeding to the gunship hangar to await their launch from the fleet with Tano and Torrent Company, Rex wished his General good hunting. Once Skywalker and his Gold Squadron pilots had begun the space battle against Grievous, Rex and Tano were joined by Kenobi in their gunship and led the assault force's launch from the fleet. Along the way to the planet's surface, Rex spared his men a few last-minute words to prepare them for the battle. After landing on the planet, Kenobi ordered Rex and Tano into the fray while he himself led the attack on the Separatist-claimed spynet facility. Rex, Tano, and Torrent Company engaged the entrenched Separatist forces in the central plaza of Kothlis's capital, Tal'cara, fighting furiously against super battle droids, droidekas, and STAP-mounted droids. With only one gunship for air support, however, the clones began to take heavy losses; not since the Battle of Teth had Torrent Company been so crippled. Rex was among those to be grievously injured and took wounds to his right arm and chest. Checkers, who was wounded less severely, stood with his Captain, ready to support him at the instant he needed it, and it was in this state that Tano, piloting a commandeered STAP, found him.

With the fight against the droids in the plaza at a temporary standstill, Tano ordered Rex and his men to fall back and tried to contact Yularen for assistance, but her attempt failed thanks to the Separatists' still-active comm jammer. Seeing no other options, Tano left to find and get help from Kenobi while the barely conscious Rex stayed to watch over his men. Tano was able to rendezvous with Kenobi and assisted him in reclaiming Kothlis's spynet facility from the Confederacy. Assisted by the Star Destroyer Coryx Moth, the Republic fleet was able to drive Grievous and his remaining forces away from Kothlis, though at a high cost. Thanks to the efforts&mdash;and sacrifices&mdash;of Torrent Company and the other clone troopers who served in the battle, the Republic was able to retain control of the planet's strategically crucial spynet facility. Rex, Coric, and the other clones who had been wounded in the engagement were transported to the Republic's Kaliida Shoals Medical Center for treatment, and Tano chose to be treated with them at the Outer Rim medcenter so that she could provide moral support for them. Although Tano's injuries were quickly fixed by the Kaminoan doctors, Rex, Coric, and several others had to undergo bacta treatment and were given their own bacta tanks. Rex and Coric were among those who made full recoveries, though the Kaminoans did not have as much success with some of the other wounded troopers.


 * UPDATE FOR CLONE WARS GAMBIT: SIEGE

War on Orto Plutonia
"Sir, the gunships can't take off in this storm. We don't have enough bikes for the entire platoon.''" "''Have the rest of the men standby here. No matter what the Chairman thinks, we're not going to war."

- Rex and Anakin Skywalker

When the Republic lost contact with Glid Station, a base on Orto Plutonia, Rex was dispatched with Skywalker, Kenobi, and a group of cold assault troops to investigate the base's lack of response. Upon arrival over Orto Plutonia aboard the Resolute, Rex, Skywalker, Kenobi, and two representatives from the orbiting moon of Pantora&mdash;Chairman Chi Cho and Senator Riyo Chuchi&mdash;proceeded to Glid Station in several LAAT/i gunships. Rex and his men were forced to use cold assault armor that, while necessary for protection from the planet's icy environment, dangerously restricted the troopers' movements in battle. After landing at the base and placing sensor beacons to survey the area with his men, Rex accompanied Kenobi into the base and discovered that the station's troopers had been slaughtered, though there was no evidence to suggest a battle with Separatist droids. Following their scouts' discovery of a nearby Confederate base, Skywalker, Kenobi, Rex, and several clones proceeded to the facility aboard Freeco bikes. Arriving at the base, which was composed of two combined XT Beetle Transports, Rex assisted Skywalker in placing sensors around the building before entering the facility with his General. Sorting through the communication records in the base's control center, Kenobi uncovered a holorecording of a large creature attacking a B1 battle droid. Though Skywalker and Kenobi speculated as to what had attacked the droid, Rex cited that the droids' log indicated that they had been last been investigating the planet's southern canyon. While Skywalker and Kenobi departed to follow this lead, Rex and the other troopers returned to Glid Station.

As a storm began to brew, Skywalker and Kenobi returned to Glid Station and reported their discovery&mdash;contrary to the findings of previous scouting parties, Orto Plutonia was inhabited by a colony of the Talz species. Upon learning of the Talz, Cho immediately ordered Rex to prepare his troops for battle, but both Jedi intervened and stated that a meeting had been arranged with the Talz to negotiate peace, much to Cho's chagrin. As the Republic forces prepared to depart for the meeting with the Talz, Rex reported to Skywalker that the gunships would not be able to take off in the storm, and Skywalker ordered the rest of the clone platoon to remain at Glid Station&mdash;despite Cho's beliefs, the Jedi did not intend to go to war with the Talz. Rex set off with the Pantoran dignitaries, Jedi, and a clone squad in Freeco bikes for the Confederate base, which had been arranged as the neutral meeting ground with the Talz. Arriving at the Separatist base, Cho told Rex to position his troopers on an adjacent ice ridge from which to ambush the Talz, but Kenobi countermanded the order&mdash;the Talz had already arrived, halting Cho's attempts to prepare an assault on them.

Leaving Rex and the clones outside with orders to avoid provoking the Talz, the Jedi and Pantorans entered into negotiations with the natives' Chieftain, Thi-Sen. Despite the Jedi's efforts to prevent such an outcome, however, Cho declared war on the Talz in an effort to expunge them from Orto Plutonia. While Skywalker, Kenobi, and Chuchi returned to Glid Station to find a solution for the conflict, Rex and his men took Freeco bikes and BARC speeders to accompany and protect Cho. When they approached several Narglatch-mounted Talz scouts, Cho immediately ordered the clones to open fire. Although Rex reminded Cho that the clones were only there for his protection, not to promote his war with the Talz, the Captain and his troops were forced into battle when more Talz appeared and ambushed them. A Talz warrior and his Narglatch attacked Rex's Freeco swoop, forcing him out of his vehicle, but Rex retaliated by shooting the warrior and his mount. He then kicked his bike over for cover, telling his men to do the same in an effort to form a defensive perimeter. As the Talz flung spears at the Republic platoon, Rex ordered his men to retreat, and though Cho refused to pull back, he was soon hit and incapacitated through the back with a spear. Rex quickly slammed a BARC speeder into an approaching Talz and defended the wounded Chairman from more of the warriors, blasting his way through Cho's attackers.

Carrying Cho onto a spare speeder, Rex joined the rest of his men in their retreat, but further on, the collapse of an ice bridge across a gorge compromised their only path to safety. Despite now being trapped between the ravine and the advancing Talz warriors, Rex was ready to fight to the last man. As spears began to fly, he signaled his few remaining men to use their vehicles as cover from the charging Talz, and the clones began to counter the Talz's spears with blaster fire. They were soon saved by the arrival of Skywalker, Kenobi, and Chuchi, who landed at their position with several LAAT/i gunships and clone reinforcements. Though the Talz were forced to halt their attack, both they and the clones had suffered from heavy casualties. After Cho, who was still adamant on eliminating the Talz, succumbed to his injuries and passed on, Chuchi&mdash;having received sufficient jurisdiction in the matter from the Pantoran Assembly&mdash;negotiated with Thi-Sen and was able to end Cho's bloody campaign. She peaceably turned over control of Orto Plutonia to the Talz, whose sovereign status had finally been recognized. With the debacle over, Rex, Chuchi, Skywalker, Kenobi, and their men departed from the battlefield aboard the gunships.

Plague on Naboo
"We may be dead men, but we could still stop those droids."

- Rex, after discovering that he and his men are infected with the Blue Shadow Virus

As the war's second year dragged on, the Separatist-allied Doctor Nuvo Vindi was discovered to be using a laboratory on the planet Naboo to resurrect the deadly Blue Shadow Virus plague, and Rex was dispatched with Skywalker, Kenobi, Tano, and the clone units Snow Wolves, Calm Tree, and Wildfire to shut down Vindi's facility. Once Tano had breached the underground lab with explosives, Rex and his men joined her in drawing the attention of the lab's battle droid defenses so that Skywalker and Kenobi could infiltrate the lab from other points without opposition. Rex and his men rappled down from an LAAT/i gunship into one of the lab's ruptured tunnels and followed Tano in cutting through a group of opposing B1 and B2 battle droids. The Republic squad's charge was cut short with the appearance of two droidekas, and Tano, Rex, and the clones began to retreat from their droid adversaries while rebounding and returning their fire. As their men began to fall to droid fire, Tano, Rex, and the remaining clones were saved by Kenobi and the clone bomb squad, who entered the passage by collapsing part of the roof on the droidekas.

Rex and Tano followed Kenobi to a junction, where the group encountered more battle droids and decided to split up: Kenobi and his troopers headed to find and deactivate Vindi's virus bombs&mdash;which had been manufactured to spread the Blue Shadow Virus throughout the galaxy&mdash;while Tano, Rex, and their squad fought the droids and kept them occupied. However, the situation worsened when Vindi remotely activated the virus bombs. Once Rex and Tano had defeated their droid adversaries, they met Skywalker, Senator Padmé Amidala, and Representative Jar Jar Binks&mdash;the latter two of whom had been captured by Vindi before being rescued by Skywalker&mdash;at one of the lab's junctions. Skywalker informed the group that one of the active virus bombs was missing and ordered Tano and Rex to split up and find Vindi's LEP servant droid, LEP-86C8, whom Amidala recalled had taken the bomb. While Tano and Rex continued the search for the bomb, Skywalker and Kenobi went to apprehend Vindi, who was attempting to flee Naboo. Amidala and Binks eventually found LEP-86C8 in the lab's arboretum and recovered the bomb from the droid, and upon being informed by Amidala of her success with finding the missing explosive, Rex and Tano quickly took the clone bomb squad to the arboretum to deactivate the bomb. The clones of the bomb squad finished disabling the bombs with only seconds to spare, much to everyone's relief. With all of the virus bombs neutralized, the threat of the Blue Shadow Virus had ended, and Skywalker and Kenobi were additionally able to capture Vindi.

While the two Jedi Generals escorted Vindi to Naboo's capital, Theed, for trial, LEP-86C8&mdash;who, unbeknownst to the Republic forces, had removed the vial containing the virus from the last bomb before escaping&mdash;used a spare explosive in the bomb room to release the virus to the laboratory. Rex, Tano, and several clones rushed to take refuge in one of the facility's safe rooms, but the group was pursued there by the airborne virus, which quickly spread through the lab. The squad was nearly sealed out of the safe room when its blast doors were triggered, but Tano held the entrance open with the Force, allowing Rex and his men to jump through the crack between the doors. The clones in turn held the doors open for Tano, who cleared the jump just in time. Tano, Rex, and their squad, however, soon discovered that the doors had not been closed fast enough; some of the virus had entered the room and infected them. Despite being contaminated, Rex believed that he and his men could still stop the lab's remaining battle droids from breaking out of the compound and releasing the virus to Naboo, even if it was his last act. Soon, Amidala and Binks, clad in enviro-suits, let the group out of the safe room, dismayed that they could not do anything to help their comrades. To prevent the droids from breaching the compound, Tano, Rex, and the clones agreed to split up and eliminate the droids. After offering a DC-15S blaster to Amidala, Rex joined Tano and another trooper in cutting off the droids from the bunker's north corridor, while Amidala, Binks, and the others took the south passage.

Regrouping with Amidala, Binks, and the other clones, Rex helped Amidala to bring down the last battle droid that was attempting to cut through the exit hatch. When the squad was confronted by two droidekas elsewhere in the compound, Rex and the rest of the squad provided covering fire for Tano as she charged and destroyed the droids. However, Amidala's suit was compromised in the ambush, infecting her with the virus as well. As the last of the droids were defeated, Rex assisted Amidala in treating four of the other infected clones, despite his own infection from the virus. When Amidala lamented on the dying clones' wasted lives, Rex replied that it was what the troopers had been "born to do." Tano, however, fainted from the effects of the virus, and Rex caught her as she collapsed. Meanwhile, Skywalker and Kenobi collected a sample of Reeksa root&mdash;a cure for the Blue Shadow Virus&mdash;from the planet Iego and returned to Naboo, successfully neutralizing the virus with the antidote. Slated to make a full recovery, Rex and the other victims of the virus were ushered away on mobile stretchers by several 2-1B medical droids onto waiting LAAT/i gunships. Before departing, the ailing Rex made it clear that he was not going to help train Binks, who had been recommended by Amidala and Kenobi for marksmanship training.

Liberation of Ryloth
"I wish General Skywalker had discussed this plan with us. The odds are very much against us."

- Rex, on the impending task of breaking the Separatist blockade

After the planet Ryloth was seized by the Confederacy in 21 BBY, Rex was deployed with Skywalker, Tano, Yularen, and a Republic fleet to eliminate the Separatist blockade surrounding the planet and allow the main body of Republic troops to land on Ryloth. However, the arrival of Separatist reinforcements caused the Republic's offensive to backfire. The Republic Star Destroyers Resolute and Defender came under heavy fire and were forced to retreat, while the cruiser Redeemer was ripped apart by enemy fire. As the two remaining Star Destroyers reached their staging area, Jedi Master Mace Windu contacted the Resolute and requested an update on the strike force's progress. Rex found Skywalker in the hangar attempting to bolster the spirits of Tano, who, in her first command position, had lost a squadron of fighters in the initial battle. Rex informed Skywalker of the incoming transmission and was told to put together a damage report, and the Captain later joined Skywalker on the Resolute bridge when Skywalker delivered his report to Windu and Kenobi, informing them of his battle group's losses. Despite the fact that only half his original forces remained, Skywalker was given one planetary rotation to eliminate the blockade. Skywalker sent Rex to locate Tano, and Rex found her in the Resolute medbay with an unconscious Yularen, who had been wounded in the earlier battle against the Separatists.

Rex informed Tano that her Master was looking for her, and she left with Rex to seek Skywalker out. When Skywalker later ordered the Defender to be evacuated, Rex assisted the Jedi General in supervising the transfer of the Defender supplies to the Resolute in the latter's hangar bay. After Tano arrived in the hangar, Rex, at Skywalker's direction, moved in to oversee the operations while Skywalker explained the plan to his Padawan. Skywalker intended to pilot the damaged Defender alone and take out the Separatist blockade's lead ship, leaving the blockade in disarray and allowing Tano, in charge of the Resolute, to eliminate the remaining enemy ships. Despite Tano's protests to her central role in the plan, Skywalker continued on and gathered Rex and the other clones together, informing them of the plan and entrusting Tano with overall command of the Resolute. Rex asked his General to leave some droids for him and the clones to take care of, though Skywalker made no promises. After Skywalker left for the Defender, Rex and the Resolute naval officer met with Tano on the bridge of the Resolute to coordinate their next move.

Rex, Tano, and the clone naval officer were contacted by Skywalker, who gave Tano a few words of support before heading back to the Ryloth system in the Defender. Upon learning the details of Skywalker's plan, Rex and the navigation officer expressed their hesitancy with the strategy&mdash;Rex believed that the odds were not in their favor, and the naval officer also voiced his doubts. To protect the Resolute from the firepower of the six remaining Separatist frigates, Tano presented a plan to angle the hull of the Resolute toward the blockade, drawing the Confederate ships in with a classic Marg Sabl maneuver, at which point the Republic starfighters would be launched, trapping the Separatists in a pincer movement. Both Rex and the naval officer were concerned about the plan's chances of success, but a revived Yularen arrived on the bridge and came to Tano's support. Upon the Resolute return to the Ryloth system, Tano departed for the Star Destroyer's hangar bay to lead the fighters in the assault on the enemy ships. Once the Defender had rammed the lead Separatist ship and the Resolute had moved into place, the Confederate frigates did not immediately converge on the Resolute as Tano had believed. Though Yularen and Rex relayed their beliefs that the droid-manned ships were not going to attack and that the Resolute would have to retreat, Tano told the two officers to be patient, as the droids tended to be rather slow.

Sure enough, the Munificent-class frigates of the blockade converged on and began to attack the Resolute just a few moments later. With their enemies in place, Tano led the Republic starfighters in the flanking assault on the Separatists. The battle continued with success, and Kenobi and Windu soon arrived with the invasion troops aboard several transports. Rex referred the Jedi Masters through to Tano, and after conferring with Kenobi, Tano had Rex dispatch a shuttle to retrieve Skywalker's escape pod. With the Separatist blockade eliminated, the Republic ground forces were able to land and eventually recapture Ryloth's capital, Lessu. Following the Battle of Lessu, Skywalker, Tano, Rex, and the 501st Legion were tasked with clearing out the remaining Confederate holdouts, which &mdash;despite their defeat in the battle &mdash;were continuing to resist surrendering to the Republic. Rex led an assault on the droid forces in the wastes close to the city of Resdin, which the Separatist holdouts were based out of. After the Captain charged the battle droid lines there and defeated several droids single-handedly, Skywalker and Tano arrived, taking out more droids themselves. The two Jedi then left Rex in command of the rest of their clone detachment while they infiltrated the Separatist lines. Rex rejoined the pair after they had defeated a tri-droid, reporting that Republic scouts had confirmed the large droid to have been the last of their enemies in the sector. Skywalker ordered Rex to prepare his men to move into Resdin, where large pockets of Separatist resistance were still located.

Rex joined Skywalker, Tano, Clone Sergeant CS-1004, nicknamed "Kano," and trooper CT-3899, nicknamed "Rookie," on an LAAT/i gunship that took them into the ruined Resdin. Once the troops had disembarked, Rex reported that the Republic scouts had not yet been able to reconnoiter the city and that the power was out to the holo-bridges in the outer sectors. Rex cautioned Skywalker and Tano before they left to reactivate the bridges, reporting that their patrols had been encountering stubborn resistance. Skywalker and Tano were able to restore power to the bridges' three generators, and with the bridges back online, the main forces were able to move into Resdin. Eventually, Kano and his clone platoon discovered a string of droid outposts in the area and received assistance from the Jedi to defeat the stations. Though the outposts were nearly cleared out, Ryloth was still under occupation by Separatist forces. As night fell on Ryloth, Rex and Sergeant Boomer, an acquaintance and trusted ally of his, went on a patrol of Resdin using All Terrain Recon Transports, and making their way through the city's streets, the two fought off the battle droids they encountered. After exiting a narrow alley and arriving at a large area below, Rex and Boomer were ambushed by groups of B1, B2, and DSD1 battle droids. Employing their AT-RT walkers' guns to defeat the droids, the two troopers went along a cliff-side path to continue on to another street.

Separatist superweapon threat
"I failed you, General. He's gone.''" "''But we're still here, thanks to you."

- Rex and Anakin Skywalker, on the escaped Kul Teska

Completing their patrol and noticing a figure running out from behind a building, Rex and Boomer dismounted from their walkers. While reporting back to Skywalker and Tano and transmitting their coordinates to them, the two clones came under attack, and the connection was severed. Waking up inside an underground hangar in binders, Rex and Boomer discovered that they had been taken hostage by the bounty hunter Cad Bane, who recruited their services for protecting a crate that he had stolen. As Separatist battle droids broke into the facility, Bane showed a detonator to Rex and Boomer, and the former deduced that it was for explosive charges in their binders. Under the threat of being blown to pieces, the two clones decided to comply with Bane's demands and protect him and his crate. Once Bane unlinked their binders and allowed them to make use of their weapons, Rex and Boomer launched an assault on the droids, using several crates as cover. Bane and the clones continued to battle the droids until Rex stopped their advance by closing the main hangar door and several auxiliary hatches from the terminals controlling them. When a Vulture droid broke through the main entrance and attacked the clones, Rex used artillery provided by Bane to make short work of the droid fighter, and the clones took advantage of the brief lull in fighting. Rex and Boomer joined Bane on the upper platform, and although Boomer believed that they could defeat Bane, Rex kept him focused on the situation at hand when Separatist reinforcements arrived in the form of B1, B2, and sabotage droids.

Skywalker and Tano eventually found Rex, Boomer, and Bane in the hangar continuing to battle waves of Separatists droids. With the battle in high gear, the two Jedi grudgingly decided to assist Bane and helped to stop the Separatists' advance. Shortly thereafter, Bane opened fire on the Jedi and clones, but Skywalker rebounded Bane's blaster fire at him, causing the bounty hunter to lose his balance and fall from his perch atop a platform. Upon learning of Bane's "arrangement" with the cuffed Rex and Boomer, Skywalker severed the clones' binders, neutralizing Bane's bargaining chips, and the clones then disarmed Bane. As explosions began to shake the hangar, Bane offered his Telgorn dropship, The Sleight of Hand, as an escape craft, and the Jedi took him up on his offer. Skywalker sent Rex and Boomer to find an elevated position from where to provide covering fire, planning to follow with Tano, Bane, and the latter's crate, which Skywalker intended to have the Republic investigate. Rex and Boomer left the hangar and took a path overlooking Ryloth's wastes, fighting their way through starship wreckage and battling Separatists droids along the way, including a number of large tri-droids. Rex then signaled to Skywalker that they were in position, and once Skywalker, Tano, and Bane had left the hangar, the Captain reported that droids were converging on them from all directions. While Rex and Boomer battled the droids above a canyon, the others cut through waves of droids below. When the Jedi's path was blocked by starship wreckage, Rex fired a rocket at the rubble, allowing them to climb over the debris. As Skywalker, Tano, and Bane continued along a cliff-side path, Rex reported that they were moving out of range and that he and Boomer would be unable to provide any more covering fire. Skywalker thanked Rex for the assistance, and the two clones took their own route to rendezvous with their comrades at The Sleight of Hand.

Rex and Boomer arrived at the dropship to find Skywalker and Tano battling the Separatist scientist Kul Teska, whom Bane had stolen the crate from. Although Teska encased Skywalker and Tano inside an energy bubble, Skywalker told the clones to focus on Teska instead of rescuing himself and Tano. Rex and Boomer complied and fought Teska, who was forced to issue an ultimatum to them: save their Jedi commanders or kill him. At that, Teska programmed the energy bubble to close in on Skywalker and Tano. Rex and Boomer decided to rescue the Jedi, and while the clones deactivated the sphere, Teska boarded The Sleight of Hand with his retrieved crate. Once Skywalker and Tano had been freed, they and the clones headed for the dropship but were unable to prevent Teska from escaping Ryloth; the Jedi were nevertheless thankful for the clones' efforts. Tano then found that Bane had fled, and she and Skywalker reported these developments to the Jedi Council. Following the discovery of Teska's underground base on the planet Behpour&mdash;from which Teska intended to collapse the Naboo sun with his gravitic polarization beam, a superweapon that he had recently completed&mdash;Rex and Cody accompanied Skywalker, Tano, Kenobi, and Windu to destroy the facility. Staging a diversionary assault on the Separatists so that Skywalker and Kenobi could infiltrate the base and disable its deflector shields, Rex and Cody marched through a canyon on AT-RT walkers, demolishing all the droids and Separatist equipment in their path. With the droids distracted, Skywalker and Kenobi were able to sneak into the base and deactivate its shields, allowing Windu and Tano in turn to enter the underground facility with the main clone detachment and secure the base's entrance.

Inside the Separatist facility, Rex and Cody met with Clone Commander CC-0411, nicknamed "Ponds," who had been sent by Windu to help set up an evacuation zone for the Republic forces. The group of clones fought their way through the base and secured a landing pad, where Rex destroyed a Vulture droid with a series of rockets. From a computer terminal, Cody used the base's emergency beacon to signal R2-D2, who piloted the Twilight to the platform to serve as an escape vessel. However, Count Dooku himself soon arrived to confront the clone troopers, and though Rex, Cody, and Ponds fired at him, Dooku simply Force-pushed them into the Twilight cargo bay and sealed its hatch shut. Dooku then used the Force to topple a large beam onto the Twilight, plunging the clones and their ship into the abyss below, but the clones and their craft survived the fall and returned to rescue Kenobi and Windu&mdash;who had begun to duel Dooku&mdash;just as the platform's supports were damaged by falling debris. While Dooku fell with the platform, Windu and Kenobi boarded the Twilight, which was unable to wait for Skywalker and Tano and promptly fled from the collapsing base. Meanwhile, Skywalker and Tano were able to defeat Teska, rescue Padmé Amidala&mdash;who had been held captive by Teska&mdash;and disable the gravity weapon. Using STAPs, Skywalker, Tano, and Amidala escaped the facility and jumped onto the Twilight, where Rex congratulated them on their victory. The Twilight left Behpour shortly before the Separatist base was destroyed by the malfunctioning superweapon.

Felucia and Devaron
"Check your fire! Hit one of those shells and this fight is over for all of us!"

- Rex, to his clone squad, during the firefight aboard Cad Bane's frigate

Rex was among the troops to be dispatched to defend the planet Felucia alongside Skywalker, Tano, Kenobi, and Cody from the Confederacy. After the Republic forces engaged the Separatists in battle, however, they began to be overwhelmed. Once LAAT/i gunship reinforcements had broken through the Separatists' space defenses and had landed in a clearing on Felucia's surface where the main force was based, Rex and Cody immediately led their troops onto the escape craft, backing into one of the vessels while returning blaster fire at the approaching waves of battle droids. Once Skywalker and Kenobi had joined Rex and Cody on their gunship, the troopships went to retrieve Tano, who had led a patrol of the dense jungle. Although Tano initially refused to retreat, the gunships landed between her forces and the droid army, forcing her to abandon the fight and join her commanders on their gunship. Lifting off in the gunships, the Republic forces escaped shortly before the ground vehicles that Tano had left behind were blown to pieces by droid reinforcements.

Although the Republic was ultimately unable to hold Felucia, it was not long before Rex returned to the war zone. Rex joined Skywalker, Tano, and Admiral Yularen aboard the Resolute on their assignment to intercept the bounty hunter Cad Bane&mdash;who had stolen a holocron from the Jedi Temple's Archives&mdash;in the Devaron system, where Bane's supposed next target, Jedi Master Bolla Ropal, had last been heard from. The Resolute arrived at Devaron just as Bane was rendezvousing with a Trade Federation fleet of Munificent-class frigates over the planet, where he had captured Ropal to access the Kyber memory crystal, a device that Ropal safeguarded. Skywalker's flagship opened fire on the Trade Federation ships, gradually decimating Bane's escort. As Bane's command ship fled from the battlefield, the Resolute targeted the frigate's hyperdrive, preventing Bane from escaping to hyperspace. Assembling their forces in the Resolute hangar, Rex rounded up three brigades of troops for the impending mission. When Rex learned from Skywalker that they were to be boarding the enemy frigate to rescue Ropal and the stolen holocron, he expressed hesitancy, as their only available assault craft were a few starfighters and the Twilight. After Yularen arrived in the hangar and met with Rex and the Jedi, Skywalker developed a plan to transport his forces to the frigate via several available AT-TE walkers. Although Yularen was appalled at the plan, both Tano and Rex found the walkers to be suitable for space and complimented Skywalker on his resourcefulness.

Despite Yularen's protests that the walkers had been designed for terrain, not space, Skywalker ordered his forces to prepare to depart the Resolute. Rex had Execute Battalion take walker ATAT300, while Carnivore Battalion was to make use of Walker 773. Once the clones' boarding party were ready, the Resolute moved into position and dropped ATAT300, 773, and another walker with the detachment of Jedi and clones aboard onto Bane's crippled frigate. While the AT-TEs exchanged blaster fire with several Vulture droid starfighters and battle droid–piloted STAPs that were deployed from the vessel, Rex and the clones provided covering fire so that Skywalker and Tano could move in and cut down the Vulture droids. Once Bane's initial defenses had been repelled, R2-D2 opened a hatch on the ship's roof, allowing the Jedi and clones to enter the vessel. Arriving on the frigate's bridge, Skywalker, Tano, and Rex stormed into the room and led a charge on the battle droids that were manning the ship's controls&mdash;however, Bane was not there. After the frigate's droid crew had been defeated, R2-D2 uncovered a record of a holographic conversation between Bane and Trade Federation Viceroy Nute Gunray from the frigate's computer. Replaying some of the transmission, Skywalker, Tano, and Rex learned that Bane now had both the holocron and the memory crystal in his possession, as he had stolen the latter from Ropal.

As Skywalker sent Rex with a squad of troopers to secure the hangar bay and disable all of the frigate's escape pods, the ship was rocked by explosions caused by the self-destruct sequence that Bane had activated. Rex then joined Skywalker and Tano in searching for the captive Ropal. When Tano found the dead Ropal in one of the ship's holding cells, Skywalker ordered Rex to have some men take the late Jedi Master back to the Resolute. The frigate's deck lights suddenly deactivated, and R2-D2 used his headlamps to lead the Jedi and their battle group through the ship's dark hallways in search of Bane. Upon blindly colliding with a protruding pipe, Rex told the rest of his men to switch their helmets' visors to night vision, pulling down his own scope to see through the darkness. Catching sight of a fleeing Bane, the Jedi and clones immediately gave pursuit of the bounty hunter. The group followed Bane to the frigate's darkened gunnery deck, where Bane revealed his amassed battle droid forces by switching on the lights. Bane and his B1 and B2 battle droids opened fire on Skywalker, Tano, Rex, and their men, who immediately returned the enemy fire.

Bane soon decided to make the fight a bit more interesting by switching off the ship's artificial gravity. Rising off the ground, Rex and the other clones used their magnetic gripsoles to latch onto various footholds and continue firing at the similarly magnetized droids. Rex secured himself onto one of the artillery guns with his magnetic boots before returning his attention to the battle droids and blasting several of them to pieces. When a blaster cannon–wielding clone hit a disabled droid and accidentally released an ammunition canister from a gun, Rex warned his men to check their aim, as the fight would come to a very quick end if one of the shells was detonated. After R2-D2 reactivated the gravity generators, Rex, the clones, and the Jedi dropped back down to the floor. As the firefight continued to rage on, Bane lured Tano into a trap, drawing her into a dead-end hallway and sealing the blast doors behind her. Skywalker rushed over to the blast doors and began to cut through them to rescue his trapped Padawan. Presently, a battle droid tripped over the head of one of its fallen comrades and misfired at an ammunition canister, and the blast from the exploding shell caused falling debris to separate Rex and the rest of his men from Skywalker. Unable to cut through the heavy mounds of rubble, Rex called out to his Jedi General and finally got a reply from him, confirming that he was alive. On Skywalker's orders, Rex headed for the hangar bay with the remaining clones to secure a transport for escaping from the doomed frigate.

Arriving in the hangar with R2-D2, Rex found that the rest of the clones were battling B1 and DSD1 dwarf spider droids that were guarding a Sheathipede-class shuttle. He and his men joined the fight for control of the shuttle, using crates as cover to return the advancing droids' fire. Soon, Rex received word from Yularen that the frigate's main reactor was exposed and would implode at any moment. Splitting his forces, Rex sent troopers Denal and Koho to find and assist Skywalker and Tano in whatever way necessary. In the meantime, the Captain and his men managed to cut a path through the droids and secured the shuttle. Beginning to herd his troops onto the escape craft, Rex finally received word from Skywalker, who had rescued Tano and was heading to the hangar with her. Rex informed the Jedi that with the reactor about to explode at any moment, the clones had to leave soon and would not be able to wait much longer for them. While the clones continued to defend the shuttle from more battle droids, the last of Rex's men finally embarked the craft. As the shuttle's engines were engaged and the ship began to lift off the ground, Skywalker and Tano arrived, and Rex waved the two Jedi onto the shuttle with the rest of the troopers. Before escaping from frigate, the shuttle picked up Denal, whom the rest of the squad had witnessed shoot Bane on an overhang above the hangar. However, the armor-clad individual was in fact Bane, who had killed both Denal and Koho and had stolen the former's armor.

Learning of "Denal's" inability to retrieve the holocron, Skywalker ordered Rex to get the squad out of the frigate, and the Jedi and their remaining forces escaped moments before the frigate's supply of ammunition exploded, ripping the ship apart. After returning to the Resolute aboard the shuttle, Rex and another trooper discovered that someone had left behind green blood on the shuttle's deck. Rex called Skywalker back into the craft and showed him their discovery, stating that the blood definitely was not from any of the clones. Skywalker and Tano simultaneously realized Bane's exploits, but when Tano confronted the bounty hunter, he incapacitated her and promptly fled for the nearby starfighters in the hangar. As Bane powered up a V-19 Torrent starfighter, Skywalker jumped onto the fighter and attempted to confront Bane, but Rex, a recovered Tano, and the rest of the clones could only watch as Bane forced Skywalker off his stolen ship and piloted it out of the Resolute hangar. Despite being alerted by Skywalker, Yularen was unable to lock down the hyperspace booster rings in time, and Bane was able to pilfer one and escape.

Break from duty
"The Senate pulled you out of Ukio after all that work?''" "You don't have to agree with the way the war is being fought to win it." "''I'll drink to that."

- Cody, Ganch, and Rex

After returning to Coruscant at some point after the defeats at Felucia and Devaron, Rex was sent to take a priority message from the Jedi High Council to Jedi General Keelyvine Reus; her Padawan, Tyzen Xebec; Clone Commander Ganch; and the Agricultural Corps worker Sanya, who had just arrived on Coruscant aboard the Star Destroyer Selfless following a campaign on the planet Ukio. Rex informed Reus that she and Xebec were to report to Master Yoda at the Jedi Temple immediately, and he also offered to take Ganch, who had been excused from duty by his General, to spend some downtime at the Republic Service Organization center while the Commander waited for Reus to complete her debriefing. Ganch accepted the offer, bringing Sanya along with him. Upon their arrival at the Service Organization's headquarters, Rex, Ganch, and Sanya were greeted by several of the Service Organization personnel, and though Sanya was barred from entering the facility because the AgriCorps was not officially recognized as an element of the Republic Military, Ganch granted her clearance as a worker who had been assigned to his oversight. Presently, Ganch received word from Reus that their debriefing was over and that he would not be required for Reus's and Xebec's next operation, and he chose to spend his time off from duty with Rex and Sanya at the Service Organization center.

Rex found Cody at one of the tables in the center's mess hall, and after introducing Ganch and Sanya to Cody, the Captain settled down to have a drink with his comrades. However, the clones' relaxation was cut short when Sanya discovered that someone had wired all of their chairs with remotely activated detonite charges. Further investigation on Sanya's part revealed that it was the clones' chairs that had been targeted and that the detonators were all linked in series. Because the charges would have to be diffused simultaneously if they were to be properly deactivated, the present Service Organization personnel volunteered their services for the job. Despite Rex's concern for the amount of coordination that such a maneuver would take, the workers were able to disable the detonators under Cody's close supervision, rendering the explosives inert. When one of the Service Organization personnel made to exit, revealing herself as the double agent, Ganch and Sanya quickly went in pursuit of the traitor.

Return to Geonosis
"Rex, tell the men to fall back!''" "But&mdash;sir, you can't be asking us to turn tail and run!" "''I'm not asking you to run, Rex. I want to draw those tanks out onto the bridge."

- Anakin Skywalker and Rex

In 21 BBY, following the Republic's discovery of a series of Separatist droid foundries on Geonosis that had been recently rebuilt by Archduke Poggle the Lesser, Rex was sent with a 501st detachment to reconnoiter the planet in preparation for a Republic assault. Upon arrival in orbit of Geonosis, Rex's task force was unable to make contact with the clone troopers on the planet's surface but nevertheless confirmed from preliminary scans that there were a large number of operational and nearly completed droid foundries on the world. In his report back to the Jedi High Council, Rex stated that the native Separatist-allied Geonosians were mounting a major revolt against the Republic and asserted that a full-scale planetary invasion would be necessary to retake Geonosis. Rex promised to provide a further breakdown of the planet's defenses before ending his transmission. Based on Rex's findings, the Jedi Council sent a massive invasion force under the command of Generals Ki-Adi-Mundi, Luminara Unduli, Kenobi, and Skywalker, along with Tano and Admiral Yularen, to recapture the planet and shut down its droid factories. After arriving in orbit of Geonosis, Rex, Cody, and Clone Commander CC-1993, nicknamed "Jet," joined their commanders aboard one of the fleet's cruisers to establish the plan of attack.

Cody led the briefing in the ship's war room, explaining the Republic's plan to execute a three-pronged assault on the Geonosian defenses and establish a staging area before launching an attack on the ray-shielded factories' shield generator. While Mundi and Jet would lead the northern advance, Kenobi and Cody would execute the central push, and Skywalker, Tano, and Rex would undertake the southward assault with their troops. With the plan set, the Jedi and their clone officers split up to begin preparations for the invasion. Once the Republic fleet was in position to deploy the assault force, Skywalker's forces of LAAT/i gunships and LAAT carriers, hauling multiple AT-TE walkers, launched from the fleet, following Kenobi's deployment and preceding Mundi's troops. All of the landing craft encountered heavy resistance from Geonosian Nantex-class starfighters and the Separatist artillery below, and the gunship carrying Skywalker, Tano, and Rex was among the first to be shot down over the planet. After the ship made a rough landing, Skywalker heaved the wreckage of the gunship away, freeing himself and his men from the fallen craft. The detachment was immediately greeted by some nearby Geonosian warriors, who targeted them with blaster cannons. While Rex and the clones returned the Geonosians' blaster fire, Skywalker charged at the enemy insurgents. Tano, Rex, and the troopers soon joined Skywalker in attacking the Geonosians at a closer range, but during the fighting, Skywalker's AT-TE walkers were destroyed, depriving the group of their remaining assault craft.

Rex reported the situation to Jet and attempted to hail Kenobi for reinforcements, but he learned from Cody that Kenobi had not reached the landing site, as Kenobi's gunship had been shot down. Ducking behind some cover with Skywalker, Rex conveyed to him and Tano the news that Kenobi would be unable to provide support. With his forces left to fend for themselves, Skywalker ordered Rex to mobilize their men in preparation to charge the enemy gunners while he and his Padawan provided cover for them. Rex assembled the troops and led them in rushing the blaster cannons alongside Skywalker and Tano, running at and cutting through the Geonosians' artillery. The assault force continued on toward the rendezvous point, but their trek led them to a canyon blocked by a massive Separatist barricade, one that was riddled with numerous gun emplacements and battle droids. Skywalker, Tano, Rex, and their men were forced to take cover from the incoming waves of fire, and several men were shot down before they could reach safety. Faced with the task of taking down the wall to clear the path to the staging area, Skywalker and Tano each took a backpack filled with thermal detonators and left Rex in charge of the troops to provide cover for them. While Skywalker and Tano ascended the barrier and began to fight their way through the thick droid defenses, Rex released a barrage of fire at a gun emplacement on the wall, eliminating it single-handedly. He then ordered his men to concentrate their fire on the droids at the top of the wall before heading to ascend the barrier himself.

Rex arrived to assist Skywalker and Tano in their fight against a pair of droidekas, sneaking up on the droid attacking Tano and walking right through its laser deflector shield. At his close range, Rex shot the droid's head, causing the reeling droid to release unfocused fire at its comrade before being deactivated; the distraction allowed Skywalker to cut through the remaining droid. With the droid defenses on the top of the barricade temporarily beaten back, Skywalker and Tano tossed their primed detonator–laden backpacks into a nearby hatch and then used the Force to levitate Rex off the wall and into the air. The Jedi jumped off the barricade with Rex falling close behind just as the barrier exploded. Skywalker and Tano used the Force to slow their descent and landed on the ground, employing the Force to safely halt Rex's fall centimeters from the ground before the wall came toppling down around them. The Jedi and clones continued on to the landing site, and after leaving the canyon, they noticed some smoldering Geonosians falling out of a nearby cliff-top cave. Skywalker recognized Mundi atop the cliff and contacted him, learning that Mundi's group had taken a detour through the cave. The two Generals joined forces and proceeded to the rendezvous point to assist Cody and Kenobi, who were in bad need of help.

Shortly after a Y-wing starfighter squadron forced the Geonosians to halt their assault on the Republic forces at the staging area, Mundi, Skywalker, Tano, Rex, and Jet arrived and met with Cody and the injured Kenobi to formulate the plan for their final task: destroying the shield generator that was protecting the droid facilities. Once Skywalker, Tano, and a small squad of clones had disabled the Geonosians' blaster cannons with EMP grenades, Cody moved in with the AT-TE walkers and eliminated both the shield generator and its artillery stations. With the shield disabled, Mundi, Jet, and Rex were able to land with the rest of the troops in the gunships and forced the outnumbered Geonosians to surrender. Both wounded from the battle, Kenobi and Mundi were transported back to the fleet for treatment, leaving Skywalker, Tano, and Rex with the task of eliminating Poggle the Lesser's near-completed primary droid foundry. The three moved their troops to the cliff adjacent to the droid factory, which was isolated on the other side of an immense canyon that could only be crossed via a bridge. Jedi Master Luminara Unduli; her Padawan, Barriss Offee; and Commander Gree soon arrived with reinforcements, and after they had landed, Rex greeted Unduli and Offee and directed them to Skywalker and Tano. Together, the four Jedi devised a plan to cripple the droid foundry: Skywalker and Unduli would launch an assault on the factory and its defenses, acting as decoys for Tano and Offee to infiltrate the facility from the catacombs beneath it and destroy it with explosives from the inside.

After the two Padawans had departed, Rex joined Skywalker, Unduli, and Gree in leading the assault on the droid foundry's defenses. Although the tactic was risky because of the Republic forces' lack of cover, the Jedi intended to tempt the Geonosians into fighting them in open warfare. Deployed factions of B1 and B2 battle droids intercepted the Jedi and clones on the bridge leading to the factory and opened fire on them, and Rex, Gree, Skywalker, and Unduli spearheaded their forces' charge on the Separatists. They soon received more than they had bargained for, however, when Geonosian fighters emerged from several spires behind the assault force, surrounding the troops. Nevertheless, the Jedi and their men continued to cut through the opposing droids and headed for the factory. With the appearance of several droidekas, Rex ordered a rocket launcher–armed trooper forward to assist the Jedi. The clone blasted the droids to pieces in one shot, and the heavy firepower of the Republic's AT-TE walkers disabled the rest of the advance droid forces. The Jedi and their troops were then faced with several droid-manned super tanks, which had been recently manufactured by the foundry. On Skywalker's order, Rex mobilized four AV-7 Antivehicle Cannons and prepared them to attack the tanks. Rex monitored the super tanks' progress with a pair of macrobinoculars, waiting for the right moment to fire on them.

Once the tanks had almost reached the other side of the bridge, Rex ordered the heavy cannons to open fire on the vehicles. The ray-shielded tanks, however, were able to withstand the thick barrages of fire from the cannons and continued to approach the Republic's position. Skywalker, Unduli, Rex, Gree, and their men were forced to take cover when the super tanks released a multitude of rockets at the Republic troops. In the ensuing bombardment, the Republic's heavy cannons and AT-TE walkers were destroyed, and the clone troopers sustained heavy casualties. Taking cover from the ongoing fire, Skywalker ordered Rex, Gree, and their men to fall back. Although Rex was adamant against retreating, he complied when Skywalker revealed that he intended to draw the tanks onto the bridge, which the two Jedi Generals would destroy to send the well-protected tanks into the chasm below. Once Rex's retreat had lured the still-firing tanks almost all the way across the bridge, Skywalker and Unduli swung under the pass hand by hand and planted explosives on the bridge's underside, heading for the droid factory on the other side of the canyon.

When the detonators were in place, Skywalker activated the charges, collapsing the span and plunging the super tanks into the abyss below. As Skywalker and Unduli waited for their Padawans outside the droid factory, Skywalker contacted Rex via comlink and questioned whether he had spotted Tano or Offee from his side of the canyon. Rex replied that he had not seen either of them but also urged Skywalker to get on one of the evacuation ships, which had just arrived, though Skywalker refused to leave without Tano. Meanwhile, Tano and Offee were intercepted by Poggle the Lesser himself and a squad of Geonosian warriors at the reactor, and with their explosives stolen by the insurgents, they were forced to use a super tank to destroy the facility's power generator, sacrificing themselves to blow up the factory. Once the dust spawned by the factory's destruction had settled, Rex and Gree found Skywalker and Unduli amidst the field of debris aboard an LAAT/i gunship, and Rex reported that the Republic's LAAT carriers were beginning to move the debris in search of the Padawans, who had been buried with the remains of the factory. Although Rex and his men did what they could to locate the trapped Padawans in the mounds of rubble, it was Tano who signaled Skywalker, Unduli, Rex, and Gree to her and Offee's location by boosting her comlink's reception with a power cell from the super tank. The four immediately proceeded to the indicated area, and though Rex offered to have the gunships move the heavy rubble, Skywalker refused; he and Unduli instead elected to lift the debris with the Force.

Once their super tank had been freed, Tano and Offee emerged from the remains of the tank, coughing and grimy but otherwise safe. After the two Padawans had been reunited with their Masters, Rex convened with Tano and Offee at one of the Republic's staging areas, where he sent the two Padawans back to the fleet for a much-deserved rest. Promising to return after recuperating, Tano and Offee departed with a medical convoy of gunships. Skywalker, Kenobi, and Unduli eventually managed to capture Poggle the Lesser and took him into custody, completing the Republic's objectives. Following the recapture of Geonosis, Tano and Offee were assigned to take the Republic Pelta-class frigate TB-73 on a supply run to a medical station near the planet Ord Cestus while Skywalker, Unduli, Kenobi, and Mundi escorted Poggle to Coruscant for trial. Rex accompanied the four Jedi Generals on a Venator-class Star Destroyer to deliver Poggle to the Republic capital under heavy guard. En route to Coruscant, Skywalker, Kenobi, and Rex joined Mundi and Unduli on the cruiser's bridge, where Unduli reported that the Padawans' cargo ship had failed to check in on schedule and was not responding to her attempts to contact it. While Skywalker concluded that something was wrong, Mundi turned their attention back to interrogating Poggle, who was proving "most uncooperative" in response to their questioning.

Before leaving with the other Jedi Generals to continue interrogating Poggle, Skywalker privately told Rex to keep a lookout for any calls from Tano, which Rex agreed to do. Rex eventually contacted the Padawans' freighter himself, and the transmission was answered by Tano, who expressed her relief to hear from him. Once Rex put Skywalker through to Tano, she reported that her convoy had been overrun by Geonosian brain worms that were capable of controlling the minds of their hosts and had already infected most of the clone troopers aboard the ship. After resolving to interrogate Poggle and wheedle from him any potential information on halting the threat, Skywalker severed the connection and headed to the Star Destroyer's detention level to confront the Geonosian Archduke. Skywalker soon joined Rex, Unduli, Mundi, and Kenobi back on the bridge, reporting Tano's predicament and continuing with the news that he had discovered how to stop the worms from Poggle. However, Skywalker evaded the other Jedi Generals' inquiries as to how he had extracted the information from the so-far unresponsive Archduke. With Skywalker's discovery that the brain worms were affected by the cold, Tano was able to neutralize the worms before they could escape from TB-73 and spread to the rest of the galaxy.

Escapades at Saleucami
"You're welcome to stay, Rex.''" "''This is your home, Cut. My family is elsewhere."

- Cut Lawquane and Rex, shortly before the latter leaves to rendezvous with Kenobi and the rest of the Republic forces

After the Jedi Order learned that General Grievous had captured Jedi Master Eeth Koth, Skywalker, Kenobi, and Master Adi Gallia mounted a rescue mission to save Koth from Grievous's clutches and also attempt to capture the cunning Separatist General. Rex joined Skywalker and Gallia aboard an Eta-class ambassadorial shuttle and met with the rest of the assembled Republic fleet in orbit of Coruscant in preparation for the assault. From his Arquitens-class light cruiser, Kenobi contacted Skywalker, Gallia, Rex, and the other clones aboard their shuttle and conveyed the plan: Kenobi himself would head to the Saleucami system with the Republic fleet, distract Grievous's forces there, and transmit the coordinates of Grievous's command ship, which the Jedi presumed was where Koth was being held captive by the Separatists. The shuttle and its embarked force would then be able to jump into the system undetected, infiltrate the command ship, and rescue Koth. The Republic forces would also make an effort to capture Grievous. While Kenobi and the Republic fleet departed for Saleucami, the shuttle continued to wait in Coruscant's orbit.

Once Kenobi and Cody had gathered and transmitted the exact coordinates of Grievous's Recusant-class light destroyer, Skywalker took the ambassadorial shuttle to join the battle over Saleucami. With Kenobi, Yularen, the Resolute, and the rest of the Republic fleet keeping the Separatist armada occupied, the Eta-class shuttle emerged from hyperspace and sped unopposed through the ongoing battle, quickly rotating upside down to dock to Grievous's destroyer. After securing the shuttle, Skywalker cut a hole in one of the command ship's hatches and boarded the destroyer with Gallia, Rex, and the rest of the clones. On Skywalker's orders, Rex and his men stayed to guard the hatch, as it was their only escape off the ship. While Skywalker and Gallia rescued Koth from captivity on the ship's bridge, Grievous broke off from his ongoing duel with Kenobi aboard the latter's light cruiser and headed back to his own ship. Gallia subsequently went to prevent Grievous from escaping while Skywalker helped the weakened Koth back to the escape hatch, where Rex and the clones helped him into the escape shuttle before joining the Jedi on the craft. The shuttle was then contacted by Kenobi, who had pursued Grievous back to his command ship with Gallia, Cody, and several other clones; Kenobi requested transport off the ship before they became trapped there. Skywalker complied and took the shuttle to a large hangar in the Separatist cruiser, where they rescued Kenobi, Gallia, Cody, and another surviving clone before the enemy destroyer was damaged by debris from the battle.

Although the Republic forces had completed their primary objective of rescuing Koth, they had not met with success in their secondary objective of capturing Grievous. However, Grievous's attempted escape from the battle with a complement of battle droids aboard a C-9979 troopship was foiled when the craft was hit by debris and was forced to crash-land on Saleucami. Kenobi resolved to head to the planet's surface with Rex and Cody to apprehend Grievous while Skywalker and Yularen continued the space battle. Skywalker piloted the shuttle into one of the Republic cruiser's hangars, where Rex disembarked, helping Koth out of the shuttle until he was escorted to a medical frigate by Gallia and a 2-1B medical droid. Rex then joined Kenobi and Cody on an Acclamator-class assault ship for the voyage to Saleucami's surface. Once the transport had landed and unloaded its troops and assault vehicles, Rex was briefed by Kenobi on their plan: instead of scattering the men to locate all of the Separatist craft's escape pods, the Republic forces would first investigate the wreckage of the enemy ship. Deploying biker scouts and AT-TE walkers, Rex and Kenobi began the search for the downed transport, with Rex himself traveling on a BARC speeder. Upon arrival at the troopship's crash site, the clone troopers began to examine the transport for potential leads as to where the craft's escape pods had landed.

Finding that the troop compartments were significantly damaged, Rex joined Kenobi and Cody on the top of the craft with trooper Jesse and relayed his findings. Following the clones' reports, Kenobi assigned teams to search for the escape pods, with Rex leading a patrol of Saleucami's wetlands. Before Rex departed with troopers Jesse, Kix, and Hardcase, Kenobi instructed the Captain to send back word before engaging Grievous if they happened to encounter the elusive General. Leading his men through the lush wetlands aboard BARC speeders, Rex became the target of a two-member droid commando sniper team. One of the droids fired at Rex with a sniper rifle, knocking him backward off his speeder with a shot through the chest. Rendered unconscious, Rex could only lie sprawled where he had fallen as his speeder crashed into some nearby brush. While Kix, the squad's medic, circled back around to protect Rex, Jesse and Hardcase eliminated the droid commandos. Lifting off Rex's helmet, Kix did a cursory examination of his Captain but was unable to discern the full extent of the damage until the Captain's armor was removed.

Realizing that they were on farmland, Jesse, Hardcase, and Kix decided to head for the grounds' homestead to find a safe place to tend to their fallen officer. Assembling a makeshift litter to carry Rex and affixing it to his own BARC speeder, Jesse led the team to the homestead, transporting Rex along the way. After receiving permission from Suu, the grounds' Twi'lek farmer, to use an eopie barn to temporarily house Rex, the three clones set up camp in the building and moved Rex onto a bench. Rex's armor and the top half of his black body glove were removed and piled on the ground so that Kix could tend to his injuries. After Kix had attached a pair of bacta patches to Rex's chest to cover up the sniper-inflicted wound, Rex finally recovered consciousness, waking up to discover from Hardcase that, had the potshot been two inches to the left, it would have otherwise gone straight through his heart and caused instantaneous death. Rex also found that he was unable to move his left arm due to nerve damage. Pulling himself up into a sitting position, Rex told Kix to patch him up so that they could continue the search. However, Kix opposed Rex's desire to continue the mission with a wound that would take time and rest to heal; Kix cited his own authority as the team medic to countermand the Captain's orders. Rex's and Jesse's argument was cut short when Suu arrived at the barn with some food for the clones. Suu's daughter, Shaeeah, then entered the room chasing a ball and, upon catching sight of Rex, blurted out that he resembled her own father, a comment that intrigued the clones.

While Suu conferred with Jesse and gave him the plate of food, Kix dressed Rex in an arm sling. Hardcase retrieved one of Rex's blaster pistols for him from the pile of his armor on the ground, placing the blaster next to Rex on the wooden bench for easy accessibility. Although Suu was kind to him, Rex sensed that something was bothering her, though he could not fathom what it was. After Suu had left with Shaeeah, Rex &mdash;recognizing that he needed to rest if he wanted his injuries to heal &mdash;reluctantly ordered his men to continue the search for Grievous without him. With Jesse in command, the three clones departed from the homestead, leaving Rex to heal his injuries. As night began to fall Rex eventually fell asleep on his bench, but his slumber was interrupted by a nosy eopie that sniffed him and then began to lick his face. Rex forced the animal away from him, sighing and wiping his face with the back of his hand before returning to sleep. Later, Rex was awoken a second time, this time by the furtive sounds of an approaching figure&mdash;the farmer, Suu's husband. Rex's eyes snapped open, but he quickly closed them again, feigning continued slumber, and slowly reached for the pistol next to him on the bench with his non-crippled arm. Once the farmer was close enough, Rex struck out at his assailant with his blaster but was disarmed by the farmer, who used a staff to knock Rex's weapon out of his hand. The unarmed Rex looked up at his greeter and was shocked to find that he was staring into a face that greatly resembled his own&mdash;the farmer was also a clone trooper.

Recognizing this as the cause of Suu's earlier unsettledness, Rex demanded to know the trooper's number and rank, but the clone instead introduced himself as Cut Lawquane and stated that he was a simple farmer. Realizing that Lawquane was a deserter, Rex called him out on his sworn oath to the Republic, but Lawquane replied that he did have a duty, only that it was to his family, not to killing for a living. The pair's heated argument was interrupted when Suu arrived with her and Lawquane's children, Shaeeah and Jek, at the barn so that the children could welcome their adoptive father home. After greeting his children, Lawquane invited Rex to dinner with his family. Although Rex initially refused, he accepted the invitation when Shaeeah and Jek begged for his attendance. Putting the top half of his body glove back on, Rex joined the Lawquanes at their home for dinner, and the two clones continued to debate their very different ideologies over a meal of roast nuna. Though Lawquane argued that the clones deserved more individuality, Rex countered that he himself was making an individual choice to serve the Republic, a decision that he did not regret.

Despite disagreeing with the Captain, Lawquane respected Rex's opinion, believing that everyone possessed a right to his or her own beliefs. After dinner, Rex and Lawquane continued their discussion of their principles over a game of dejarik holochess. Following Rex's inquiries into the cause of his desertion from the Republic corps, Lawquane recounted his service in an engagement shortly after the Battle of Geonosis. An ambush by enemy battle droids had caused him to flee the carnage-laden battlefield, and he had then begun to question his apparent expendability in the war. A survivor of the Battle of Geonosis himself, Rex sympathized with Lawquane and stated that he, too, had lost many brothers&mdash;whom he had come to regard as his family and home&mdash;during the course of his service in the war. In the meantime, Shaeeah and Jek received permission from Lawquane to play outside, prompting Rex to express his admiration of the Lawquane children to their father. In response, Lawquane promised to fight to his last breath to keep his children safe, contrary to Rex's belief that he was a coward. Rex, Lawquane, and Suu were roused from their household activities when Jek and Shaeeah returned to the homestead in screams. Learning from Shaeeah that the two were being followed by monsters, Lawquane grabbed a pair of macrobinoculars to verify her claim. Training his binoculars through the dark fields, Lawquane spotted some twenty droid commandos had been deployed from a crashed Separatist escape pod and were beginning to surround the homestead.

Preparing for a confrontation with the battle droids, Lawquane locked the building's front door and sent Suu upstairs with their children. As Lawquane opened up his supply of weapons and handed Rex a blaster pistol not unlike the ones that he normally carried, Rex volunteered a plan to catch the droids in a crossfire, but Lawquane cited his injuries as a weakness against the droids and refused. Although Rex was taken aback by this assertion, he grasped the intentions behind Lawquane's refusal when the clone farmer clarified them: Lawquane was asking Rex to serve as a last line of defense for his family while he himself took point against the droids. Telling Lawquane that he would take care of them, Rex joined Suu, Shaeeah, and Jek in the upper level's bedroom. Presently, the droids launched their attack on the homestead and eventually made it past Lawquane, who warned his fellow clone about the approaching droids. While Suu hid with Jek and Shaeeah by the room's bunks, Rex took up position, waiting at the end of the hallway adjacent to the stairwell doorway. Once the droid commandos had entered the hallway, Rex forsook his hiding spot and opened fire on them, gunning down a pair of the droids. While rolling away from and exchanging fire with another of the droids, Rex managed to hit his foe in the head, but not before the droid released a barrage of fire at the platform that Rex was crouching on.

Rex fell through the floor and landed on the ground beside Lawquane, losing his grip on his blaster in the process. One of the droid commandos seized Rex by the throat, but Lawquane immediately grabbed Rex's fallen blaster and shot the droid's head cleanly off. Released from the droid's choke hold, Rex stumbled against a wall, gasping for air. Despite the injuries that the two clones had received, the droid commandos had been repelled, ending their threat to the Lawquanes' peace. As morning broke, Rex prepared to rendezvous with the rest of the Republic forces. Abandoning his arm cast, Rex retrieved his armor from the barn and re-donned his gear, including his punctured pauldron chest plate. He also borrowed one of Lawquane's eopies, onto which he loaded the remainder of his gear. When questioned by Suu if he was going to turn Lawquane in for his desertion from the Grand Army, Rex stated that doing so was his duty. However, he also mused that in his condition, he might not "remember" his meeting with them, and his discretion earned him a relieved thanks from Suu. Rex was soon contacted by Kenobi and reported his recuperation to the General, who had been unable to capture Grievous. Although Lawquane offered Rex a place at his home, Rex politely refused, not intending to impose on the clone farmer's family, and stated that his own family was elsewhere. With that, Rex bade goodbye to Lawquane, Suu, Jek, and Shaeeah and departed on his eopie mount to rendezvous with Kenobi. The Captain left the homestead with a broader view of a clone's loyalties and duties as a souvenir of his experience.

Mandalorian affairs
"Assassin droid. How did that monster end up in the hold?''" "''Question is, who smuggled him on board?"

- Rex and Anakin Skywalker, upon defeating an assassin probe aboard Duchess Satine Kryze's Coronet

Following the emergence of the Mandalorian Death Watch, a terrorist group that had come to staunchly oppose the Republic-allied Duchess Satine Kryze of Mandalore and her pacifistic government, Skywalker, Kenobi, Rex, and Cody were assigned to escort Kryze to Coruscant, where she intended to reaffirm her people's neutrality in the war before the Galactic Senate. Skywalker, Rex, Cody, and their clone squad met with Kenobi&mdash;who had been conducting an investigation into rumors that Kryze had joined the Confederacy &mdash;at a spaceport in Mandalore's capital city, Sundari, where Kryze's starship, the Coronet, was preparing to depart. After checking in with Kenobi, Skywalker and the clones joined Kryze and her entourage on the Coronet, which promptly left for Coruscant. En route to the Republic capital, Skywalker and Kenobi briefed their troops in the Coronet cargo hold and told them to stay vigilant for the Death Watch, which would stop at nothing to assassinate Kryze before she reached Coruscant. Rex and Cody then sent their men to begin their rounds of the cargo bay while Skywalker and Kenobi went to meet with Kryze.

During their patrol, Rex and Cody bumped into the astromech droid R2-D2, who appeared to have been frightened by something. The two clone officers also found that they were unable to make contact with two of their men, Mixer and Redeye. Rex promptly contacted the Jedi, and once Skywalker returned to the cargo hold to assist in investigating the disturbance, the clones followed him and R2-D2 with headlamps ablaze through the labyrinth of containers in search of the missing Mixer and Redeye. However, the group's focus shifted when they discovered an open and overturned crate, and Skywalker ordered Rex, Cody, and their men to find the box's missing contents. The disappeared cargo soon manifested itself in the form of a large assassin probe droid, which began to attack Skywalker. Rex, Cody, and their men intercepted the droid during its fight with Skywalker, firing at the droid and deactivating it before it could crush the Jedi General with its large legs. However, a second assassin probe took advantage of the clones' distraction to head for the turbolift shaft that led to the Coronet dining room, where Kryze, Kenobi, and the former's senator associates were eating. Skywalker, Rex, Cody, and their men ran for the lift but were unable to prevent the droid from prying the shaft open and climbing up to the dining hall. As Skywalker speculated the possibility that more assassin droids were aboard the ship, the fallen assassin probe dispatched an army of tiny but deadly probe killer droids that surrounded and began to overwhelm the Jedi and clones with their numbers.

Rex, Cody, and their men opened fire on the small droids, and despite some casualties, they were eventually able to repel the majority of the nuisances. Although Rex mused how the monstrous assassin probe had managed to get on board the Coronet, Skywalker instead focused on a more specific question: who had smuggled it aboard to eliminate Kryze. After finding the protocol droid that was in charge of the Coronet cargo manifest, Skywalker checked the droid's records and determined that someone had used a Senate stamp to approve the shipment of the crates that had contained the assassin droids. Acting on this lead, Kenobi launched into an interrogation of the four senators aboard the Coronet to determine which one of them had smuggled the assassin droids aboard, while Skywalker and the clones searched the cargo hold for the third and final assassin probe aboard the ship. While patrolling the cargo bay with Rex, Cody stopped to examine a fallen clone helmet and unwittingly became the victim of the probe killer that was hiding in it. Cody fell to the floor as he tried to fight off the droid, and when Rex attempted to grab the droid off his comrade, two more probe killers jumped onto the Captain and attacked him as well. Both clone officers were saved by the timely arrival of Skywalker and R2-D2, who deactivated the clones' tiny assailants with lightsaber and electric shocker, respectively. However, right after Rex reported to Skywalker that he had not seen the remaining assassin probe, the droid jumped out from behind several crates as if on cue and bowled the Captain over.

The assassin probe climbed on top of Rex and prepared to impale him with its front pincers, but the unfazed Rex caught the droids' legs and kicked his attacker off him before it could do any damage. Rex and Cody fired at the droid as it escaped up a nearby wall, and though both clones landed shots on the droid, it was not until Skywalker threw his lightsaber at the droid and severed most of its legs that it toppled back to the floor. Running over, Rex slammed his foot down on the incapacitated droid and rained down blaster fire on its cranial unit, preventing the monstrosity from hatching its probe killer spawn. A triad of Separatist Droch-class boarding ships then attacked the Coronet and penetrated its hull to deploy squads of super battle droids. Rex and Cody joined Skywalker in one of the ship's hallways, where they and their men returned the droids' fire. With Skywalker's assistance, the clones were able to bring about the droids' defeat and left the hallway littered with enemy carcasses. After the Coronet finally reached Coruscant and docked at a landing pad, Rex, Cody, and their men disembarked with the Jedi, their assignment to protect Kryze a success.

After the Trade Federation initiated a blockade of Pantora as part of a plot to force the world to join the Confederacy, Rex accompanied Skywalker to see Senator Padmé Amidala off from a Coruscant landing pad. As Amidala prepared to leave Coruscant, Tano arrived and reported that Chi Eekway Papanoida and Che Amanwe Papanoida&mdash;daughters of Baron N. Papanoida, the newly elected Chairman of Pantora&mdash;had been kidnapped, and Skywalker sent his Padawan to aid Senator Riyo Chuchi in investigating the matter. Tano and Chuchi were subsequently able to help Papanoida rescue his daughters from the Separatists and restored good relations between Pantora and the Trade Federation, ending the Federation's blockade of Pantora. Rex later returned to Mandalore with Skywalker and Tano aboard an Eta-class shuttle to drop off Tano, who was to teach the New Mandalorian cadets at Mandalore's Royal Academy of Government. Tano's less official mission, however, was to assist Duchess Kryze in halting an ongoing black market conspiracy that was perpetuating a harrowing food shortage on Mandalore. After landing at a port in Sundari, Rex and another trooper stood by while Skywalker and Tano were greeted by Kryze and her Prime Minister, Almec. With Jedi General Kit Fisto expecting them, Rex reminded Skywalker of their imminent obligation, and they soon left Mandalore to meet up with Fisto. Tano and her students eventually found that Almec was the architect of the black market plot, and they played a crucial role in thwarting his attempted overthrow of Kryze and bringing him to justice.

Trouble with a beast
"Stay with General Kenobi. I'm on my way.''" "''Better hurry, sir. You're missing all the fun."

- Anakin Skywalker and Rex

Rex and Commander Ponds were among the Republic troops to be dispatched with Generals Skywalker and Mace Windu to defend the planet Malastare from the Separatists and secure the world's vital fuel resources for the Grand Army. However, as the several-thousand-strong droid army began to overwhelm the Republic forces, Supreme Chancellor Palpatine authorized the use of the Republic's recently developed electro-proton bomb to defeat the Separatists. After being tasked with leading the clones' defense of Doge Nakha Urus's Imperial palace until the bomb was detonated, Rex proceeded to the front of the palace's defense lines to command the Republic troops and monitored the massive battle droid army's approach with a set of macrobinoculars. Once the droids launched their attack on the clones, Rex held the line with his men and led them in returning the incoming barrages of fire. The clones were assisted by squads of Insectomorph-mounted Dug cavaliers, who also fought to repel the droids.

Presently, a starfighter squadron was deployed with the electro-proton bomb and dropped the bomb in the middle of the droid army, creating an explosion that transformed into an electromagnetic pulse. The expanding wave deactivated the droids and additionally disrupted the clones' helmet systems for a short time. As Rex and his men were recovering from the blast, the ground began to sink from the effects of the bomb, and the clones immediately made a run for it as a sinkhole opened up. Rex almost fell into the sinkhole when he passed over an unstable plateau, but he managed to jump to and reach higher ground with his troops' help. While search parties were dispatched to rescue the troops that had been engulfed in the sinkhole, Rex joined Skywalker, Windu, Urus, R2-D2, and Doctor Sionver Boll at the Imperial palace, where communications were re-established with Palpatine. After Windu and Urus conferred with Palpatine on the status of the fuel treaty that the Dugs' council would have to ratify for the Republic to gain access to Malastare's fuel reserves, Rex relayed the news to the Jedi that contact had been lost with the rescue team in the sinkhole. Skywalker and Windu subsequently departed to, respectively, attend to the Dug leaders and aid the rescue team in the crater, and they soon found that the electro-proton bomb had awakened a gigantic and uncontrollable Zillo Beast in the crater.

As night fell, Rex met with Skywalker, Windu, Boll, and R2-D2 at Urus's palace to contact Palpatine and discuss the problem of the Zillo Beast&mdash;while the Dugs wanted to kill the creature off, the Jedi wanted to preserve it, as it was one of the last of its kind. To appease the Dugs and get the fuel treaty ratified while also saving the beast, Skywalker devised a plan to knock out the beast with the Republic's RX-200 Falchion-class assault tanks and then transport the creature off-world, thereby keeping the beast's survival a secret from the Dugs. The Jedi were able to render the Zillo Beast unconscious, and Rex was present when Urus and the other Dug leaders subsequently signed the fuel treaty in the Imperial palace. Yet despite the Republic's hard-won success with gaining access to Malastare's fuel resources, the matter of the Zillo Beast still remained. Although the Jedi had planned to transport the Zillo Beast to an uninhabited Outer Rim world so that it could live in peace, Palpatine made a change of plans, ordering that the creature was to be initially taken to Coruscant for study before it was released into the wild. Rex, Skywalker, Windu, and Boll returned to Coruscant aboard an Acclamator-class transport, and the Zillo Beast was transferred to the Republic Science and Technical Center so that Boll could study the makeup of its unusually durable armor-like scales. Despite Boll's containment measures, however, the Zillo Beast broke out of its heavily guarded facility and began to rampage across Coruscant, heading for the Republic Executive Building.

After joining an LAAT/i gunship force led by Kenobi and Windu that had been sent to contain the beast, Rex contacted Skywalker through R2-D2, both of whom were with Palpatine and Senator Padmé Amidala in the Chancellor's Suite at the Executive Building, and confirmed that he was to serve with Kenobi for the time being. However, when Rex, Windu, and Kenobi arrived with their detachment of clones and Falchion-class stun tanks at the Executive Building, they found that the Zillo Beast had taken hold of the H-2 executive shuttle that Palpatine, Skywalker, Amidala, R2-D2, and C-3PO had been using to leave the building. As Yoda and Aayla Secura arrived, Rex, monitoring the situation through a pair of macrobinoculars, noticed that Skywalker was cutting the shuttle in half with his lightsaber and notified Windu of this development. Kenobi realized that Skywalker intended to free himself and his trapped comrades by severing the ship in two, and the Jedi moved to protect the group. While Yoda and Secura distracted the beast, Skywalker managed to completely slice the shuttle in half, freeing it and its passengers from the Zillo Beast's grip.

Windu and Kenobi quickly used the Force to catch the half of the ship that was carrying Palpatine and a Senate Commando, securing the pair's safety. While the stun tanks targeted the Zillo Beast, the LAAT/i gunships launched with Rex, Windu, Kenobi, and their men aboard and fired upon the beast as well. Left with no other options to suppress the rampant beast, Palpatine ordered the gunships to release some toxic gas bombs that Boll had developed to kill the creature. Though the Republic forces succeeded in containing the creature and preventing more civilian blood from being shed, the victory came at a price, as one of the last of the Zillo Beasts had now been wiped out. As morning broke on Coruscant, the slain Zillo Beast was transported back to the Science and Technical Center on an X-Alpha heavy cargo sled, and Rex, the five Jedi, Amidala, and R2-D2 and C-3PO met with Palpatine, mourning the loss of the creature. While Rex and the others departed from the Executive Building, however, Palpatine secretly gave Boll orders to clone the Zillo Beast. After the Zillo Beast fiasco, Rex and Skywalker were given command of the Grand Army's Third Legion for an assignment on the planet Balith; there, they were to intervene in a large-scale civil war on behalf of the Republic. While Tano remained at the Jedi Temple on Coruscant to focus on her Padawan studies, Rex picked up Skywalker at the Jedi Temple with a Nu-class attack shuttle, and they then rendezvoused with a Venator-class Star Destroyer in Coruscant's upper atmosphere for the voyage to Banith.

Personality and traits
"What if I am choosing the life I want? What if I'm staying in the army because it's meaningful to me?''" "And how is it meaningful?" "Because I'm part of the most pivotal moment in the history of the Republic. If we fail, then our children and their children could be forced to live under an evil I can't well imagine." "If you were to have children, of course, but&hellip;that would be against the rules, wouldn't it? Isn't that what somebody programmed you to believe, Captain?" "''No, Cut, it's simply what I believe. It doesn't matter if it's my children or other people's children."

- CC-7567 expresses his ideologies during a discussion with Cut Lawquane

Gruff, no-nonsense, and tough as carbonite nails, CC-7567 was an aggressive and battle-scarred veteran of the Clone Wars. Hardened by countless engagements with the Confederacy, Rex, as he chose to be named, retained a reputation as one of the best and toughest clone troopers in the galaxy. Freethinking, fearless, steadfast, and resilient, he preferred to be more diplomatic than the Advanced Recon Commandos when it came to operating with his superiors, though he did not hesitate to give higher-ranking Jedi commanders his "blunt opinion." True to his genetic engineering, the brave and selfless Rex often put his assignments before his own safety. Rex led from the front and, in some cases, would have fought ahead of his Jedi General, Anakin Skywalker. Although Rex was far from reckless, his courage and willingness to jump into the fray helped the Republic to win numerous victories. His outspokenness and aggression notwithstanding, Rex faithfully executed orders &mdash;even when he disagreed with them &mdash;with little concern for his own well-being. During the war, he swore to protect all Republic citizens from harm, and his promise extended even to the disagreeable Chairman Chi Cho. The basis for Rex's support of the Republic was that the war was crucial to the preservation of civilization. He came to regard his clone brethren as his home and family, and he never forgot the many brothers whom he had lost during the course of his service in the war. Rex's first loss of a unit at the Battle of Teth ultimately toughened him to an even greater degree, and the fact that he had been beaten to a standstill, stared death in the face, and lived to tell the tale with his troops was visible in his character from then on.

Rex's loyalty to the Republic and his fellow troopers never wavered. He often become concerned for the safety of his Jedi officers, particularly those of Skywalker, Ahsoka Tano, and Obi-Wan Kenobi, whom he served under during the war. As such, Rex was hesitant to follow orders that put the Jedi in danger, especially those that came from the Jedi themselves,  and was willing to sacrifice his life for the Jedi. Although he witnessed enough of his comrades die to know that there was nothing glorious about war, Rex was unafraid to do his duty as a soldier of the Republic, even if it meant placing his own life and the lives of his troops in jeopardy, and was willing to fight to the last man if necessary. During the Second Battle of Geonosis, Rex even disregarded a retreat as cowardly and was initially adamant against executing such a tactic before he saw its strategic side. However, he never wanted to leave anyone behind if possible and greatly cared for his troops. While he was good at keeping up a stoical front, he was extremely passionate about certain matters. He despised using the tally sensor because it was inconsiderate and was also an admission that he did not personally know his men. Rex was both angered and saddened by the near-eradication of Torrent Company at Teth and the loss of troopers Vere and Ince during a later rescue mission. After Vere's death, Rex pushed his anger to one side so that it would serve as fuel for the job at hand with the intention of releasing it later when no one would be around to see him break down. Sometimes, he even saw death as a method to assuage his belief that he had failed his men and to stop wondering how many more of them he would lose the next day. Rex's care for his rookie troops on JanFathal was so great that he was surprised to realize that his instinct was not to look after Tano, whom he usually guided, but to take care of his men.

Born to fight for the Republic, Rex held the Separatist battle droids in contempt for all the damage that they had wrought on both him and his clone brethren, and cutting through droids frequently became his way to avenge his fallen brothers. He did not allow himself to be intimidated by his enemies, and he even expressed humor in the direst situations, such as during the Battle of Teth. When overwhelmed by battle droids during that campaign, Rex did not waver in his commitment to the mission, despite the possibility that the battle could be his last. However, Rex's challenges were not only posed by his enemies. His commitment to fight for the Republic was tested multiple times simply from his service in the war. While he was aware that he and his clone brothers had been bred to fight for the Republic and had been forced into the war without a choice, Rex made the best of the situation. He knew that the politics and ideology of fighting were beyond his influence and instead focused on the day-to-day activities of looking out for his brothers in arms and killing his opponents before they killed him, often with a steely determination. Whenever the morality behind his manufactured birth was tested and his "programmed" loyalty to the Jedi and the Republic was subsequently challenged, he dealt with his doubts by recalling the fact that the men under his command depended on him to lead them&mdash;and that he would never be able to fight for the Republic if he questioned or scrutinized his birth's ethics. In this way, Rex put aside his insecurity with his loyalty and service for the greater good of the Republic so that he would be able to assist the Jedi in winning the war. His loyalty was so potent that even if he had not been born to serve, he found the prospect of abandoning his brothers and friends to be unimaginable. He often stayed focused by keeping himself busy, which he found easy to do with his numerous tasks as a soldier. His compassion and selflessness as a commander was evidenced at Kothlis when, despite being severely injured, his first concern was for his troops and comrades, not himself.

Rex's strong loyalty to the Republic and the Jedi came into stark contrast with Sergeant Slick's betrayal of his comrades and his hatred of the Jedi. After Slick was revealed to be a Separatist spy, Rex displayed contempt toward him but was visibly unsettled with his comrade's perspective that the clone troopers of the Republic were slaves to the Jedi. Despite Slick's claims that he had been striking a blow for all clones, Rex drew the conclusion that the Sergeant's actions&mdash;particularly the fact that he had put his brothers' lives at risk by helping the Separatists&mdash;showed that he did not love and care for them as he so believed. Rex's allegiance to fighting for the Republic remained undeterred during his discussions with the clone deserter Cut Lawquane. When Rex first met Lawquane, the Captain's lack of patience for those who would abandon their duty came into play, and he made his contempt for the deserter known. After assuming a more respectful attitude toward Lawquane, Rex maintained that his beliefs had not been programmed into him, as Lawquane suggested, but were simply his own. Although Rex believed that his continued service made him a part of the most pivotal moment in the Republic's history and that the Grand Army's failure to defeat the Confederacy would mean the insurrection of an evil that he could not well imagine, the Captain came to respect Lawquane as possessing a different type of loyalty&mdash;not to the Republic, but to his adopted family. When the time came to end his stay with Lawquane's family, Rex forwent his initial adamancy on turning Lawquane in for abandoning his oath of duty and instead returned Lawquane's hospitality by choosing not to report him as a deserter. Though Lawquane was still a deserter, Rex concluded that he was certainly not a coward. Before departing, Rex politely refused Lawquane's offer of a place at the farm in order to avoid encroaching on Lawquane and his family.

Rex's abilities in strategy were exemplified during his involvement in planning an assault on the Separatist blockade over Ryloth with Tano. Although he did not criticize Tano's idea to employ a Marg Sabl maneuver, he carefully identified the obstacles that hindered the plan's chances of success. Rex did not always look to a soldier's rank for information and instead judged by experience, which, he believed, outranked everything. When addressing the rookie troopers of Rishi Station, Rex used the derogatory "shinie" slang to underline their inexperience. However, this did not prevent him from caring for trooper Hevy's life and attempting to discourage him from sacrificing himself to win the battle. Rex was additionally pleased when the clones grew to the challenge; he placed a handprint of Rishi eel blood on Echo's armor to recognize the trooper's valor and to mark his transition from a rookie soldier to a seasoned warrior, and he also honored Hevy's ultimate sacrifice during the battle. Following the successful campaign, Rex inducted both Echo and Fives into the 501st Legion for their valiant service, and he later promoted them to Advanced Recon Commandos for their courage in defending Kamino during a Separatist invasion. Rex even found that the two troopers reminded him of himself. During the war, Rex became acquainted with a number of his brethren. He was good friends with Commander Cody, whom he worked with in several missions, and their relationship mirrored that of Skywalker and Kenobi&mdash;Rex's superb instincts in battle won Cody's admiration, although Cody often worried that he put too much faith in them. After Rex fought alongside Sergeant Boomer countless times, Boomer became one of the Captain's most trusted allies and a close friend as well. Rex additionally shared an acquaintance with Commander Ponds and came to rely on fellow 501st trooper Denal for his instincts and expertise in combat. Aboard Captain Gilad Pellaeon's Leveler, Rex found that he was comfortable with others that were involved in the war and understood him, as opposed to Coruscant civilians who never would.

Despite his respect for the Republic civilian contractors' willingness to live or die by their workmanship's quality, Rex was not partial to a spacegoing navy and preferred to have ground under his boots whenever possible. Some of his views were less open-minded, however, as he initially could not understand the pacifist Lurmen's choice to avoid fighting and believed that they had no pride. Rex had certain manners of etiquette that he strictly observed, including his troops' privacy. After the five rookie clones under his command had opened up their own comlink channel, Rex avoided intruding on them, even if they were cursing him for the recent loss of trooper Vere, and would have only overrode the frequency in an emergency. Rex sometimes made judgments based on what he was and was not trained in and respected diplomatic negotiations as a kind of fighting that he was not trained for. He learned what he could from the Republic's HoloNet News bulletins and was used to absorbing information in this manner from his early Kaminoan flash training. Although Rex was not easy to rattle, he was visibly startled when he overheard trooper Checkers imply that he considered him to be the best officer he could have found to serve under, and he snapped at Tano and Checkers to "stow the chatter" after this comment. Even when he was deeply unsettled about the comm jammer situation at Kothlis, Rex was disciplined enough to maintain a focused outward attitude, and his unease could only be sensed by Skywalker through the Force. Rex's distinguishable traits were noticed by a number of his comrades during the war. Pellaeon described him as a solid, sensible chap who allegedly told very good jokes when not being the obedient solider around Skywalker. Cody admired Rex as a smart man and also respected his superb instincts, and Kenobi believed that the Captain always thought on his feet. Checkers saw Rex as the best commanding officer that he could have found as a means to survive the war, and Callista Ming interpreted Rex as a hands-on commander who, on account of his duty to the Republic and his brethren, did not want to look like he was letting others do the dirty work by sitting back while his comrades reconnoitered JanFathal's capital of Athar.

Serving closely with Skywalker throughout the Clone Wars, Rex learned much from the Jedi General's style of leadership and adopted Skywalker's inclination for unconventional and unorthodox combat tactics, which often yielded spectacular results against the enemy. Rex was as headstrong and as brave as Skywalker, and it was the duo's similar lack of "by the book" methods that allowed them to get along so well. From his service with Jedi during the war, Rex witnessed them in action and learned to both respect and never doubt their abilities, and the Republic's Jedi Generals in turn came to rely on him during battles. However, he sometimes disapproved of the preference to debating over fighting that some of the Jedi possessed. Unlike those Jedi, Skywalker matched Rex in bravery, aggression, and decisiveness, and the General's "soldiery" traits helped Rex to form something of a friendship with him. Rex learned much from Skywalker's style of leadership and shared his occasional recklessness, and the time that he spent with Skywalker was such that he even became aware that his General had feelings for Senator Padmé Amidala, though he was unaware of the full extent of their attachment. Rex was proud of the trust Skywalker placed in him, and as a soldier, Rex was loyal to Skywalker both on the battlefield and at a personal level. When Skywalker was away from his troops, Rex kept him regularly apprised with the situation to prevent his General from facing the consequences of being caught out of the loop. Rex was not upset when Skywalker was unable to return to reinforce the Captain's diminished squad during the Battle of Teth and understood the Jedi's urgent mandate to return Rotta the Huttlet to Tatooine, true to his belief that the mission always came first. In addition to his friendship with Skywalker, Rex was acquainted with Kenobi, Skywalker's own former Master. Rex's abortive attempts at sarcastic jokes on the battlefield aimed at procuring a laugh from Kenobi made him look forward to the day that he would succeed in doing so.

After meeting Tano on Christophsis, Rex was concerned with her initial naivety and arrogance toward her commanders, particularly Skywalker. Once the Padawan and Captain reached an understanding of each other, they began to form a strong bond and supported each other as the galaxy-shaking war progressed. Among the lessons that Rex taught Tano was that smart remarks were unhelpful and disruptive in times of protocol, especially when they were directed at her Master. Rex often addressed Tano as "kid" instead of a more formal title. Rex's attitude was such that Skywalker came to trust him with Tano, and Skywalker additionally recognized that some of the Padawan's lessons were better learned from the Captain instead of himself. Rex helped Tano through several tough situations, including on Maridun, where their group was forced to find medical attention for a grievously wounded Skywalker, and at JanFathal when her beliefs in the Jedi Code were challenged. Rex additionally guided her in her first command position at Ryloth and assisted her by covering for her with the troops when she expressed her insecurity with her role. Tano came to respect Rex, while the Captain's belief in her abilities prompted him to defend her against Pellaeon's hesitancy with her proficiency and also caused Rex to encourage Skywalker to maintain his faith in his Padawan during a confrontation with Ventress on Taronda.

Rex chose to keep the origins of his nickname to himself throughout the war. He found hair under a helmet to be annoying and bothersome, and as such, he regularly shaved and used hair polish to keep his hair from interfering with his concentration. Even so, he dyed his hair a light blond and let it grow out to a certain extent. At one point, Rex chose to support the Bylluran Athletic bolo-ball team when it reached the finals&mdash;despite, as Gilad Pellaeon put it, the Clone Captain's training on Kamino away from the usual sense of "tribalism" that most sports fans harbored&mdash;and briefly dyed his hair blue as an expression of his support. However, Rex eventually deemed his new hair style to be undignified and inappropriate for a commanding officer and shaved it to better fit in with his black-haired troops. Rex had a small scar beneath his lower lip. His teeth were considered to be perfect, and he sometimes bared them in a feral smile when filled with adrenaline for a coming engagement with the Separatists.

Skills and abilities
"That wasn't so tough.''" "Still sharp as ever, Rex." "''It's all in the wrist."

- Rex and Ponds, after the former defeats a Vulture droid

Rex was able to speak Galactic Basic Standard. His natural abilities reached the attention of the Kaminoan cloners and led him to be recommended for supplementary training on Kamino. With extra training and intensive programmed learning, Rex was versed in a variety of tactics and fighting styles and was knowledgeable in recon and military tactics. A skilled warrior, he was proficient in armed and unarmed combat, the latter of which was evidenced in a brawl with Sergeant Slick on Christophsis, and he had expertise with jetpacks. He was also capable of leading specialty clone units when the need arose. His abilities were such that he even came to be considered one of the best soldiers in the Grand Army. Like any good soldier, Rex knew his weapons but also knew that equipment alone could not win a battle&mdash;it was a soldier's mind that was his greatest tool. Rex relied on intelligence rather than weaponry, combining a commando's gift of improvisation with an infantryman's toughness. Having received related training on Kamino, Rex was adept in mental resistance and was able to shield himself from a Force mind trick performed by the Dark Acolyte Asajj Ventress. Rex was proficient in blaster combat, and his skills in marksmanship were evidenced numerous times throughout the war. He was able to hit fast-moving targets, such as a flying fuel cell on Skytop Station, and was also able to hit a blaster emplacement on Geonosis several hundred meters away.

Rex had a fast reaction time and responded quickly to the appearance of a Rishi eel on the Rishi moon, immediately firing at the large creature and killing it with a single shot to the eye. Rex recognized that if he did not kill the Confederacy's battle droids first before they killed him, they would surely take the opportunity to end his life, and he therefore resolved to eliminate all of the enemies that stood in his path. Rex was quite casual in combat against the battle droids, as noted by Skywalker during the Battle of Christophsis, and he displayed a certain smoothness in battle; he cut through his enemies and made full use of his weaponry without pause or hesitation, regardless of whether his opponents were Separatist droids on Ryloth or aggressive Talz warriors on Orto Plutonia, the latter of which he battled with a steely determination. Rex was able to hold his own against the Separatists' massive tri-droids and Vulture droid starfighters, and though he learned to dread the latter even more than super battle droids, he stood his ground against them. He was quite strong and was able to lift the injured Chairman Chi Cho without assistance. Additionally, he was able to escape defeat at the hands of a menacing assassin probe on the Coronet by employing his strength to grab and prevent the attacking droid's pincers from impaling him; he then managed to kick the large droid off himself. Despite having a temporarily paralyzed arm on Saleucami, Rex was able to roll and fight in blaster combat against several droid commandos as if he did not have the physical impediment.

Equipment
"You sure you don't need civilian clothing? You're rather visible.''" "''I'd rather trade armor advantages against stealth. And we're not going to be hanging around long."

- Gilad Pellaeon and Rex, on the mission at hand to JanFathal

Rex used a suit of Phase I clone trooper armor that was customized with the white and blue of the 501st Legion. His helmet displayed Mandalorian Jaig eyes as battle honors and was equipped with a fold-down, night vision–enabling rangefinder scope and a pair of removable headlamps with a viewing distance of forty feet. His helmet was additionally equipped with audio pickups that gave him superb hearing and infrared vision. Rex utilized a variety of tools&mdash;a vibroblade in one of his gauntlets, a comlink-equipped left gauntlet, a medpac in his utility belt, and a rappel line. He also made use of the traditional leather kama half kilt, constructed out of thick anti-blast armor, and wore a semi-blue pauldron over his left shoulder. The latter piece of gear was punctured by an enemy droid sniper through the chest plate during an operation on Saleucami.

Rex sometimes wore generic white clone trooper armor instead of his usual white-and-blue armor. While on Orto Plutonia, he was forced to employ cold-weather armor decorated with Jaig eyes and sported a rebreather hood and a thermal suit so that he could maintain protection from the cold. Although it was necessary for the hazardously cold planet, the extra gear dangerously limited his movements in battle. Being skilled in marksmanship, Rex made use of a variety of weapons in combat. He preferred to make use of a pair of DC-17 hand blasters for their speed, a choice that caused him to resemble the dual pistol–wielding Jango Fett, the bounty hunter whom he was cloned from. He cut his hand blasters' holsters at his waist to be able to draw them more quickly. Rex sometimes used a DC-15S blaster and a DC-15A blaster rifle. On JanFathal, he used a DC-15 with a grenade launcher mod that the weapon was allegedly not supposed to have. When the situation called for it, Rex used a JT-12 jetpack, as he possessed expertise with the device.

Development and portrayal
"Rex was originally based on an ARC trooper from the comic books named Alpha. But we had Anakin, Artoo, Alpha, and now Ahsoka all hanging out, and someone pointed out that they were the A-Team. So, George changed 'Alpha' to 'Rex.'"

- Supervising Director Dave Filoni discusses Rex's development

The character of CC-7567 was created for the 2008 Star Wars: The Clone Wars film and television series. After being featured in February 2008 as a promotional mail-order figure that kicked off Hasbro's Star Wars: The Clone Wars toy line, Rex made his first appearance in Star Wars canon in The Clone Wars film's July 2008 novelization and junior novelization. As the television series' primary clone character, Rex continued his role as a recurring character throughout the series' first, second, and third seasons, which were released in 2008, 2009, and 2010, respectively. He appeared extensively throughout media related to the series, including the tie-in webcomics to the series;  the Slaves of the Republic story arc of The Clone Wars comic series; the first three installments of the graphic novella series;   the novels The Clone Wars: Wild Space, The Clone Wars: No Prisoners, Clone Wars Gambit: Stealth, and Clone Wars Gambit: Siege of the novel series by authors Karen Traviss and Karen Miller; and several young readers books. He was also featured in the video games Jedi Alliance and Republic Heroes and was offered as a character in Cartoon Network's online The Clone Wars Game Creator.

Although his appearance in the first season episode "Rising Malevolence" was cut from the final version of the episode, it was released in the "Director's Cut" edition in The Complete Season One DVD collection. As far as non-canonical material went, Rex was featured in the LEGO Star Wars: The Clone Wars online comic series and LEGO's The Quest for R2-D2 game and film. He will be given a role in the upcoming LEGO Star Wars III: The Clone Wars video game.

Voice actor Dee Bradley Baker provided Rex's voice throughout the television series, as well as the voices of all other clone troopers. To make the distinction between the multiple identical clone characters, Baker has portrayed Rex with a somewhat deeper voice than the series' other clone troopers based on his confidence and aggression. This has been more prominent during clone-centric episodes such as "Rookies," "The Hidden Enemy," and "The Deserter," all of which featured Rex as a leading character and expanded his personality. The latter two episodes in particular contrasted him with Sergeant Slick and Cut Lawquane, two clone characters that were established to have abandoned their sworn loyalty to the Republic for different reasons. These comparisons only served as a testament to Rex's unwavering loyalty to the Republic and his comrades, and he gained popularity among Star Wars fans young and old.

At first, the creators of The Clone Wars series decided to put in Alpha-17, the Advanced Recon Commando featured throughout Dark Horse Comics' Star Wars: Republic comic book series, as the television series' primary clone character. However, Series Producer George Lucas objected to this because including the character would make too much of an alliteration between the major characters&mdash;"Anakin," "Ahsoka," "Artoo/R2-D2," and now "Alpha"&mdash;so a different clone character was created. It was Lucas himself who provided the name "Rex," securing this new character's role in Star Wars canon. Rex's chin scar was based on the blemish that actor Harrison Ford&mdash;who portrayed the smuggler Han Solo in the original trilogy of Star Wars films&mdash;made famous in the Indiana Jones saga.

Merchandising
"Rex is a strong, courageous character who is clearly one of the heroes of The Clone Wars. However, we were reluctant to use Rex because a very powerful attribute to our initial concept was the ability to look into the character's eyes, and Rex's helmet took away the emotional connection of eye contact. Recognizing this void and understanding the need to bring emotion and intensity back into the artwork, PILOT co-founder Chris Ford digitally painted an incredibly strong visual element with the ominous 'blue sky', giving the effect that you are on the frontlines in the Clone Wars."

- Bill Concannon

Rex was featured in the 2008 Clone Wars and Clone Wars Tactics expansions of the Topps Comany's Star Wars PocketModel Trading Card Game, as well as the 2009 Galaxy at War expansion set of Wizards of the Coast's Star Wars Miniatures series. From 2008 on, Rex was featured in several sets of Hasbro's Star Wars: The Clone Wars toy line, and in 2008 he was also made into a LEGO mini-figurine.

In 2010, Rex became the face of Star Wars merchandise packaging as part of the new "Clone and Sky" design. Initially, the design firm that developed the artwork was reluctant to use Rex, as the original intention had been to look into the eyes of the character featured on the design, and Rex's helmet took away from this emotional connection. To address this void, the element of the "ominous" blue sky was added to portray the effect of being on the front lines of the Clone Wars.

Inconsistencies
"A clone commander assigned to a detachment of clones under General Anakin Skywalker, Commander Rex is a steadfast and resilient officer who is unafraid to do his duty, even if it means placing himself and his men in mortal danger."

- The Clone Wars Campaign Guide erroneous opening line for Rex's entry

There have been numerous inconsistencies with Rex's rank. In particular, Star Wars Insider 103's The Clone Wars: A Who's Who Guide and the 2009 Wizards of the Coast sourcebook The Clone Wars Campaign Guide, along with the Jedi Alliance Prima Official Game Guide and other media, claimed that Rex was a clone commander. However, in the majority of sources directly affiliated with the television series&mdash;including the episodes and their corresponding online guides, the multiple novelizations of The Clone Wars film, The Visual Guide, The Art of Star Wars: The Clone Wars, The Official Episode Guide: Season 1, The Clone Wars novel series, and many other sources  &mdash;Rex is referred to as a clone trooper captain. This article makes use of his confirmed rank as a captain.

There has also been a discrepancy regarding the extent of Rex's mental resistance abilities. The Clone Wars: The Visual Guide suggested that Rex was not able to resist the mind trick performed by Asajj Ventress during the Battle of Teth, but the novelization of The Clone Wars film maintained that he was indeed able to avoid succumbing to the Dark Acolyte's mind influence. This article assumes that the latter's interpretation is correct. In addition to these inconsistencies, there have been a few minor errors regarding Rex in several sources. In Escape from Kadavo, Obi-Wan Kenobi addresses a clone trooper who is clearly wearing Rex's customized blue-and-white armor as "Cody." Also, the Decoded re-airing of the episode "Jedi Crash" mistakenly refers to Commander Bly as Rex.

Republic Heroes Nintendo DS edition
The Nintendo DS version of Republic Heroes presented very different portrayals of Rex's roles in several episodes of the television series' first season. In the game's interpretation of the Mission to Skytop Station, General Grievous is not present, and the Republic squad is divided into two groups: the first is led by Skywalker and Tano, while the second is comprised of Rex and Denal. The two groups approach the station's reactor from different directions, and Skywalker eventually has the two clones find a control panel and use it to reactivate all systems in Sector AA-23. After successfully destroying the station's reactor, Rex and Denal are then ordered to rendezvous with the Jedi at the hangar so that they can escape aboard the Twilight. The destruction of the reactor, however, triggers a failsafe lockdown, which seals the hangar's doors. R2-D2 discovers that there are two terminals controlling the lockdown; both of them need to be deactivated in order for the hangar doors to be opened. Arriving in the hangar bay, Rex and Denal defeat a number of battle droids there and prepare the Twilight for takeoff. Tano and R2 then join them in the hangar, and the astromech droid deactivates the first terminal. Traversing through the outer hull of Skytop Station, Skywalker reaches the second terminal and deactivates it as well, thus shutting down the lockdown. As several IG-86 sentinel droids pin down Tano, Rex, and Denal inside the Twilight, Skywalker defeats them and opens the hangar doors before escaping the station with the group. This portrayal of events opposes the one featured in the episode "Duel of the Droids," in which the mission was first depicted.

Rex is also featured in a different mission that conflicts with the first season episode "Lair of Grievous." Rex and two other clone troopers assist Jedi Master Kit Fisto in infiltrating General Grievous's castle on the third moon of Vassek, while in the episode, it is Jedi Knight Nahdar Vebb, Clone Commander CC-3714, nicknamed "Fil," and several other clones who accompany Fisto. Leaving the two clones outside, Fisto and Rex navigate through the lair's mazes and fight numerous B1 and B2 battle droids, eventually confronting Grievous himself. After a brief duel with Fisto, Grievous retreats further into the castle, and Rex tells the troopers outside to contact the Republic fleet at the planet Bestine and ask for reinforcements &mdash;an action that Fil does during the episode. The troopers, however, fail to complete their orders, as their only means to contact Bestine&mdash;their Nu-class attack shuttle&mdash;is destroyed by a Vulture droid. Fisto and Rex continue their pursuit of Grievous but are forced to split up. The Jedi Master eventually faces Grievous for a second time before retreating on his Delta-7B fighter.

Rex later participates in a mission to the space station Juma 9, which is a strategic Confederate outpost instead of a Republic mining facility like in the other editions of Republic Heroes. Using Separatist clearance codes that were previously stolen from Grievous's lair on the Vassek moon, Rex and another trooper accompany Luminara Unduli and Plo Koon to infiltrate the station. While Unduli and Koon set off to capture the station's bridge, Rex and the other clone get into position and prepare to breach the station's hull if needed. The two Jedi Masters eventually get trapped by droids between two force fields, and Rex is called in to assist them. He and the trooper move through the station and rescue the two Jedi. After doing so, the clones are ordered by Koon to secure the nearby vicinity while the Jedi Masters continue to make their way to Juma 9's bridge. Unduli and Koon are ultimately successful in completing their mission and taking over the bridge. Besides the Juma 9 mission, Rex is also featured in a bonus level that sees him racing through a battle zone to a checkpoint on Christophsis. Because of these storylines' contradictions of the television series that would require too much fan-based speculation to be implemented in the existing canonical biography, this article assumes that the Nintendo DS missions are non-canonical.

Non-canon history
The following lists scenarios that have not been recognized as having canonical status for their contradictions to and disregard for established continuity.

Star Wars Miniatures: The Clone Wars ad
"What are we up to now, 64? 65?''" "Who knows'' what'll happen next?"

- Rex and Ahsoka Tano, after defeating Grievous

In the Star Wars Miniatures: The Clone Wars ad, Rex and Ahsoka Tano defeat the bounty hunter Durge with a squad of several clone troopers and a Wookiee. General Grievous soon appears, but the clone troopers quickly incapacitate the cyborg, severing several of his limbs with blaster shots. Walking away from their victory, Rex questions how many orders they had been given.

LEGO Star Wars online comics
"This is Captain Rex reporting in. We've encountered heavy resistance, but the mission is proceeding as planned. &hellip;Or not."

- Rex, as an OG-9 spider droid appears

In the LEGO Star Wars: The Clone Wars online comic series, Rex and a squad of clone troopers are assigned to undertake a mission, but their LAAT/i gunship is shot down on a desert planet by battle droids. Just as Rex reports that the mission is proceeding as planned, several B1 battle droids and an OG-9 homing spider droid appear. The spider droid knocks Rex over, and he and his troops open fire on the droids. While the other troopers attack the droid menace, Rex finds a clone from Batch 82-4 that is avoiding the battle out of his arachnophobia, a trait shared amongst the rest of the batch. The spider droid returns and charges at Rex and the trooper, and the two take refuge in the remains of the gunship. Rex explains to the scared trooper that it is a droid, not an actual spider, and he then watches as the clone takes up arms and defeats the spider droid single-handed. As Rex congratulates his men on their victory, however, three more spider droids appear.

Rex joins Skywalker, Kenobi, Tano, and Rotta the Huttlet in a search for Asajj Ventress. The group's AT-TE walker comes across a squad of IG-100 MagnaGuards and their Rogue-class Porax-38 starfighter, but a B2 super battle droid and several IG-227 Hailfire-class droid tanks appear and blast the walker off its feet. Emerging from their damaged vehicle, Kenobi, Tano, and Rex fight the new arrivals while Skywalker battles the MagnaGuards at the landing platform. However, Ventress appears with the Death Brick weapon and throws it at the three Jedi before escaping with the battle droids. Rex jumps into the line of fire and blocks the brick, which simply bounces off of his head harmlessly. Commander Cody then arrives with an LAAT/i gunship and transports Rex, Skywalker, Tano, and Kenobi away from the planet.

Rex is later sent with Kenobi, Cody, and a detachment of clones to rescue Skywalker and Tano in a space battle, but the group is pulled to the surface of a nearby planet by a Separatist tractor beam. R2-D2 is able to open the door of Rex's gunship&mdash;which had been jammed from the crash&mdash;in time, and Rex arrives with Plo Koon to save Skywalker, Tano, Kenobi, Cody, and a squad of troops from Ventress and an army of battle droids. The Separatists are repelled, and Rex reports R2-D2's actions to Kenobi. Rex is also present when Koon is given an award for his valiant efforts in the battle. Later, aboard Supreme Chancellor Palpatine's Venator-class Star Destroyer, Rex and Cody are present when Palpatine fires a clone scout squad in person for their incompetence and failure to find a missing R2-D2. Rex additionally accompanies Skywalker to Orto Plutonia when it is attacked by the Separatists, traveling to the surface with Skywalker and several other clones in containers carrying Freeco bikes and defeating the droids on the planet.

In The Quest for R2-D2 short film, Rex and Cody are personally dispatched by Supreme Chancellor Palpatine himself to find R2-D2, who has gone missing in action. On an ice planet, the two clone officers lead a patrol and encounter a squad of B1 and B2 battle droids along with an OG-9 spider droid and an All Terrain Armored Transport. Skidding across the ice, Cody drops a projectile, and Rex swings at the piece with his blaster. The projectile cuts through the droids and hits the AT-AT walker, collapsing it onto the spider droid and overturning a nearby NR-N99 Persuader-class droid enforcer. With their enemies neutralized, the two clones build a Nu-class attack shuttle from the rubble. Rex and Cody then join Skywalker and Tano in raiding a Separatist Lucrehulk-class Droid Control Ship and rescue R2-D2 from Grievous, Count Dooku, and Asajj Ventress. As the Jedi and clones prepare to face off against the Separatists, Yoda and Obi-Wan Kenobi arrive. Yoda uses the Force to collapse the floor beneath the Republic's three adversaries, forcing Dooku, Ventress, and Grievous into space, and additionally forms a CR90 corvette. The group uses the craft to escape the Droid Control Ship shortly before it explodes. Following the victory, Rex and Cody accompany the Jedi to the "Skywalker World" theme park.
