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. Born on Kamino, 7567 underwent additional clone trooper training by recommendation of the Kaminoan cloners and took the nickname "Rex" once his learning had been completed. In 22 BBY, Rex entered into Republic service in the opening battle of the Clone Wars on Geonosis. A loyal soldier despite his aggressive personality, Rex earned both a promotion to captain and a reputation as one of the toughest clones in the galaxy. Assigned to patrol the lawless and dangerous Outer Rim Territories with Jedi General Anakin Skywalker, Rex worked as the Jedi's second-in-command and learned to match Skywalker's bravery and his habit of employing unorthodox strategies in battle. Rex came to befriend Clone Commander CC-2224, nicknamed "Cody," and the two joined their respective Jedi Generals, Skywalker and Obi-Wan Kenobi, on many missions that led them across the galaxy.

Rex formed a bond with Skywalker's newly assigned Padawan, Ahsoka Tano, during the lengthy Battle of Christophsis and fought to the last stand in the following Battle of Teth, despite the near-eradication of his 501st detachment, Torrent Company. Rex's participation in campaigns at Bothawui, Skytop Station, JanFathal, Rishi Station, Vanqor, Quell, Maridun, and Orto Plutonia led him to become instrumental in numerous Republic victories. Surviving an encounter with the deadly Blue Shadow Virus on Naboo, Rex helped to liberate Ryloth from the Confederacy of Independent Systems and halt a following Separatist superweapon threat on Behpour. After failed campaigns at Felucia and Devaron, Rex participated in the Second Battle of Geonosis, which saw the Republic emerge victorious in destroying several Separatist battle droid foundries on Geonosis. A hunt for the Confederate General Grievous on Saleucami led Rex to encounter the clone trooper deserter Cut Lawquane, whom Rex eventually came to respect.

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

- Rex, to Cut Lawquane

The clone trooper with designation CC-7567 was born circa 32 BBY on the planet Kamino to serve in the Grand Army of the Republic. A clone of 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 went through additional training and intensive programmed learning to enhance his skills. After the completion of his training, 7567 took the nickname "Rex," although he kept the origins of his nickname to himself. In 22 BBY, Rex participated in the opening battle of the Clone Wars on the planet Geonosis alongside trooper Denal and the rest of his clone brethren. Surviving the battle, Rex continued to serve in the Republic army in the ongoing war against the Confederacy of Independent Systems and the Separatist Droid Army.

Rex's aggression earned him the reputation of one of the toughest clones in the galaxy. He was eventually promoted to the rank of clone captain and was given command of the Grand Army's famed 501st Legion unit, with which he was assigned to patrol the "most dangerous and lawless sectors of the galaxy" within the feared Outer Rim Territories. Able to quickly absorb information as taught by his Kaminoan flash training, Rex learned everything he knew about Republic citizens' everyday lives from HoloNet News bulletins. Rex was eventually assigned to Jedi General Anakin Skywalker, and as Skywalker's second-in-command, the clone captain developed a certain friendship with his Jedi General. During the war, Rex befriended Clone Commander CC-2224, nicknamed "Cody," whom he served with in a number of missions. Rex was also acquainted with Commander Cody's own Jedi General, Obi-Wan Kenobi. At some point in the war, Rex participated in a battle on the planet Tibrin alongside Cody and several Jedi, a dire campaign that he 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 22 BBY, Rex and Cody were dispatched with a contingent of troops under the command of Generals Skywalker and Kenobi to liberate the planet Christophsis, which had been seized by the Confederacy. After the Republic battle group had set up a base, Clone Sergeant Slick and his platoon reconnoitered the planet and located two parallel towers facing the north and south as a suitable location from which to ambush the Separatists. Seeking to attack the advancing battle droids from above, Skywalker and Rex stationed their men in the North tower, while Kenobi, Cody, and Slick were based in the South tower. As the droids approached the plaza where the towers were located, the column of Separatist troops unexpectedly split into two, and a squad of droids ambushed Kenobi's men in the South tower. Skywalker signaled clone pilot Hawk for an evacuation from the South tower, and the Jedi General, Rex, and their men used the grappling hooks of the clones' DC-15A blaster rifles to traverse the gap between the two towers. The droid forces in the plaza below opened fire, but Skywalker, Rex, and their force were able to reach the adjacent tower.

After Skywalker, Rex, and their unit arrived to reinforce Kenobi, the entire detachment took a turbolift to the roof of the tower. Pursued by a tactical droid and his droid troops, the two Jedi engaged their adversaries at a closer proximity while Rex, Cody, and the clones provided covering fire. Hawk's LAAT/i gunship approached the tower, and trooper Gus stole the tactical droid's cranial unit before escaping with the Republic forces and transferring the pilfered part to Rex. Back at the Republic base, 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. The clone officers reported their findings to their Jedi Generals, and while Skywalker suggested that there had been a breach in security, Kenobi suspected that there was a spy amongst their troops.

Skywalker and Kenobi departed to investigate behind enemy lines, leaving Rex and Cody behind to find and apprehend the traitor with orders to keep the Jedi's mission confidential. Shortly thereafter, Cody was alarmed to find an activated comlink on a nearby table; someone had been eavesdropping on the entire conversation. Rex noticed a figure in the hallway who was too far away to be recognized&mdash;Sergeant Slick, who had secretly betrayed the Republic to Dark Acolyte Asajj Ventress and the Confederacy. Once Rex noticed Slick, the Separatist spy fled, ignoring Rex's orders to stop. While giving pursuit of the spy, Cody and Rex lost sight of him. However, because of the arrangement of the base's hallways, the two clones followed the spy's trail and deduced that he had fled into the mess hall. Entering the room, the pair discovered that the only people there were their clone brothers. Rex and Cody then returned to the command center, where they continued their investigations. Rex used the astromech droid R2-D2 to check the records of external communications. Tracing an irregular wavelength to Sergeant Slick's barracks, Rex and Cody decided to individually interrogate the members of Slick's platoon under the belief that one of them was the spy.

Despite protest from Slick, Rex and Cody began to question his men in their barracks. When trooper Chopper revealed that he had broken war protocols by stealing battle droid fingers from the battlefield, Slick put Chopper's credibility in question. However, while stating to Chopper his right to silence, Slick accidentally revealed that he was aware of the Jedi's mission, information he would only know if he had been listening on the conversation earlier through the active comlink. Cody confronted the spy, but Slick attacked both him and Chopper before escaping. As Cody and Rex tracked the clone traitor to the gunship landing platform, they discovered several pre-planted thermal detonators. The pair took cover just before the explosives went off and destroyed the landing platform, the AT-TE walkers, and the weapons supply depot. Slick was spotted running into the command center, and Rex and Cody entered the room, engaging in a ploy to bait the saboteur out of the air ducts where he was hiding. While Cody secretly took the ammunition out of his blaster and left the weapon on the table, Rex appeared to leave for the south exit to get the generators restarted.

Once the door had closed behind him, Rex instead laid in wait to assist Cody in confronting the traitorous Slick when the time came. After Slick emerged from his hiding place in the air ducts and stole Cody's blaster, pointing it at the clone commander, Rex re-entered the room, effectively trapping the spy. Determined to stand behind his beliefs, Slick pitted himself against his clone officers. Slick grabbed Rex's blaster and knocked him over, and both Cody and Slick lost their weapons when the former disarmed the latter. Cody trapped Slick before he could escape through the exit and engaged him in close combat, prompting Rex to pull Slick away while calling the sergeant out on his disloyalty to his brethren. Slick head-butted Rex, knocked him to the ground, and used the "groin popper" maneuver to dislocate his leg, causing Rex enough pain for him to cry out. Cody was able to knock out Slick, and the spy was locked in handcuffs.

After the Jedi had returned to the base from a duel with Ventress, Rex and Cody presented them with the arrested Slick. The traitor attempted to justify his actions, only to receive a verbal backlash from his disappointed clone officers. After Slick had been taken to lock-up, Rex and Cody reported the spy's sabotage of the weapons depot to Skywalker and Kenobi, who replied with their discovery of the full strength of the Separatists' main droid force. With greater numbers than the Republic had originally believed, the Confederacy&mdash;under the command of General Whorm Loathsom&mdash;launched an attack on the Republic forces, which had become based out of Crystal City. After several days, the Jedi and clones were able to beat back their enemies, and the Separatist droids retreated. The Venator-class Star Destroyer Hunter was dispatched for supplies, and Rex took advantage of the lapse in fighting to shave his hair and reviewed casualty reports on his datapad near the Republic's temporarily-established medical center. The clone captain conferred and joked with Clone Sergeant Coric and wounded trooper Ged, the former of whom was serving as the Republic medic on duty and the latter of whom had received a shoulder injury.

At that moment, the Confederate forces launched another assault, and Rex immediately grabbed his rifle and sprinted for the street without a second thought, joining Skywalker and Kenobi in defending their position. Once Cody had arrived, he joined Kenobi and the troops in taking up battle positions and returned the battle droids' fire. In the meantime, Skywalker, Rex, and a clone platoon proceeded through a route parallel to the main street, making their way behind the droid lines. Cutting through the crystalline buildings, Rex recalled how just days before, Crystal City had been a landscape that "seemed carved out of glittering gems" before being crippled by the ongoing battle. Rex, Sergeant Coric, Ged&mdash;who had been patched up for battle&mdash;and the rest of the men accompanied Skywalker to an energy sphere tower. Leaving the majority of the troops there to ambush the street-level droids, Rex took a small group of clones to accompany Skywalker to the roof and surprised the Separatists' three advancing tri-droids from above. The clones used JT-12 jetpacks to safely descend to the ground below while the Jedi General landed on one of the droids himself. The group's combined efforts brought the three droids down, and the clones proceeded to attack the still-advancing droid lines from behind.

The Republic's AV-7 Antivehicle Cannons eventually forced Loathsom and his forces to pull back once more. A Republic Nu-class attack shuttle landed in City Plaza, and Kenobi believed his new Padawan learner to be on board the ship. Rex was amused with the freedom that Skywalker had from training an apprentice, but the Jedi Generals soon found that the shuttle had not brought reinforcements&mdash;in place of the expected troops was young Padwan Ahsoka Tano, who had been apprenticed to Skywalker. Rex went to check in with the observation post, where he was introduced to Tano. Rex was surprised to meet Skywalker's Padawan, as his Jedi General had previously stated that he would never take an apprentice. Rex chuckled when Tano nicknamed her new Master "Skyguy," but Skywalker, annoyed with Tano's arrogance and lack of respect for him, told his captain to give her an "acquaint of the position," to which Rex complied.

Rex used various elements of his training to help Tano better understand her role in the army, and 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 was no longer arrogant or disrespectful to her superiors. While walking with Rex near the heavy cannons, Tano noticed that the Confederacy was deploying a deflector shield, which Rex noted to be impenetrable to long-range fire 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 strike on the enemy forces. Skywalker decided to take his Padawan to infiltrate the droid lines and eliminate the shield generator, while Kenobi and Rex would draw the advancing droids into the buildings in an attempt to stall for time. After the two Jedi had departed, Rex and Kenobi attempted to use the heavy cannons in defense, but they confirmed that the artillery was indeed useless against the droids' shield. Using an unencrypted comlink channel to make the Republic's retreat appear more convincing, Rex ordered the clone forces to fall back before switching back to a secure channel.

Rex eavesdropped on the Confederacy's voice traffic and learned that General Loathsom had ordered his forces to target the heavy cannons. As soon as the deflector shield had passed over them, Kenobi led a charge on the battle droids, and Rex and his men lured the Separatists into the buildings. As the battle droids stepped over a barrier made up of fallen shells, Rex used the opportunity to find cover around the corner of the comm post building. However, the droids fired a missile at the comm post, and Rex was winded and knocked to the ground by a chunk of debris that hit him in the back. Musing over a mixture of anger at his troops' losses and guilty relief at his own survival, Rex ordered his men to retreat. At the command center, Rex met with Kenobi and volunteered to fire the cannon at the droids inside of the shield, a risky action that would cause fatal overpressure. Kenobi instead ordered the clone captain to marshal his troops in a defense of the heavy cannons while he himself himself delayed the droids. Despite his reluctance to leave the Jedi Master to fend for himself, Rex complied and retreated while Kenobi engaged the droids in combat.

As the shield approached the cannons, Rex and his men took cover in some fallen rubble and opened fire at the approaching droids. When Rex learned that Kenobi had "surrendered" to Loathsom, the clone captain deduced that the Jedi Master was simply stalling for time and rallied his men to continue fighting. Just as Rex was about to shoot a Kerkoiden tank commander, Skywalker and Tano destroyed the shield generator. Sighting the receding shield, Rex killed the tank commander out of sheer relief. Rex ordered the heavy cannons to commence firing, and the Republic employed its renewed artillery usage to eradicate the battle droids. Admiral Wullf Yularen returned to the system with several Star Destroyers and broke through the Confederate blockade, sending down an Acclamator-class assault ship with several clone trooper units for reinforcements. With the battle over, Rex allowed himself to feel the deaths personally. The clone captain helped Sergeant Coric search through the debris for surviving troopers before departing to pick up Skywalker and Tano from the shield generator station. Rex's LAAT/i gunship retrieved the two Jedi and returned to the command base, and the clone captain 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 the kidnapped Rotta, son of Hutt crime lord Jabba Desilijic Tiure, in order to win Jabba's favor to allow the Grand Army safe passage through Hutt-controlled space. Captain 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 located on a cliff, Skywalker elected to commence with a vertical assault up the cliff face. 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. The battle droids defending the monastery opened fire on the approaching craft, and Clone Lieutenant Hawk&mdash;the pilot of the gunship carrying Skywalker, Tano, Rex, and some of their troopers&mdash;closed the gunship's blast shields to deflect the incoming fire. The gunships landed in the forest below the cliff, and the Republic forces targeted the droids above. The AT-TEs returned fire at the droids, providing cover for the Jedi and clones to take refuge in an overhang.

Rex initially thought a falling object descending toward himself and his unit to be an explosive device and instinctively ducked, but, a moment later, found that it was a fallen battle droid, which he confirmed to not be booby-trapped. Using 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, Rex watched in horror as the droids' laser fire caused one of the AT-TEs to lose its grip on the cliff. The walker plummeted to the ground, eradicating all of the troops below it. B1 battle droids on Single Trooper Aerial Platforms arrived to attack the clones, and hanging from his rappel line, Rex targeted his blaster fire at the flying droids before Skywalker eliminated the craft. The clone unit was able to defeat the droids and reach the monastery, but the battle group had been cut in half from the assault.

Upon arrival at the summit, Rex called in a gunship to casevac the fifteen troopers that had been wounded in the fight. Skywalker and Rex deduced from the 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 four other clones to retrieve the Huttlet from the monastery. Entering the dimly-lit castle, the clone troopers activated their helmets' headlights for better vision. A droid appeared and claimed to be the monastery's caretaker, thanking the Jedi and clones 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, leaving Rex and his men to guard the entrance. Rex returned to the monastery courtyard and effectively secured the castle with his troops. As it neared midday, Skywalker contacted Rex and reported that he and Tano had found the Huttlet. Rex sent Sergeant Coric to help transport Rotta with a backpack, and Coric returned with the Jedi and the Huttlet. The two Jedi prepared to leave the planet with Rotta on a gunship that Rex was keeping on standby, but 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 via holotransmission, two Confederate C-9979 landing crafts approached the monastery and launched Vulture droid starfighters. With the droids attacking the Republic detachment in the courtyard, Tano returned to the stronghold with the Huttlet. Conferring with Rex on the weak chances of getting Tano and Rotta off-planet, Skywalker resolved to organize Torrent Company in a defense of the monastery. Rex dispatched Sergeants Coric and Hez and their squads to provide covering fire for the rest of the force. However, the Republic's only remaining AT-TE walker was shot down, and Torrent Company began to take heavy losses. Rex eventually entered the monastery, where he mobilized Torrent Company. With Rex and the rest of the men inside the stronghold, Skywalker ordered him to shut the monastery door. At first, Rex refused, as Skywalker would be left outside and forced to fend on his own against the droids. At the Jedi General's continued orders, Rex finally 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.

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 astromech droid R2-D2 to escape the castle while Rex remained with Torrent Company to defend their position. The Separatist forces&mdash;under the command of Dark Acolyte Asajj Ventress&mdash;were eventually able to break through the door's lock, allowing B1, B2, and DSD1 dwarf spider droids to enter the stronghold. Due to the battle droids' sheer numbers, Torrent Company began to be overwhelmed. Rex watched as his men were eliminated one by one before being knocked to the ground. Feigning death, Rex secretly contacted the other survivors through his troops' private frequency and discovered that only five of his men remained, including Sergeant Coric.

Rex destroyed the battle droid next to Ventress with one of his blaster pistols and then targeted the Dark Acolyte herself. However, Ventress immediately drew her double-bladed lightsabers and deflected the laser shots. Ventress 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 performed a mind trick on the defiant clone captain, 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 warn his Jedi General of the Dark Acolyte's presence. Unaware of Rex's exploit, Ventress threw him aside and departed to personally confront Skywalker, leaving her droids to guard the clone survivors.

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 beeping. As the droids converged on him, Rex destroyed several of the droids closest to him in combat and stole a blaster. 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 the 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 brought down an advancing Vulture droid, using it as cover to engage the droids at a closer proximity.

As the battle droids demanded the clones' surrender, General Kenobi&mdash;who had arrived at Teth with reinforcements in the form of Commander Cody and the 212th Attack Battalion&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. Several LAAT/i gunships approached the monastery, deploying 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 was still the priority. Rex understood his Jedi commanders' position and replied that he and his men would be able to hold out on their own, stating that the mission "always came first" 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. Rex and the clones were joined once again by Kenobi, who had returned after dueling Ventress inside the monastery. Rex voiced his doubt that Skywalker and Tano would make it to Tatooine in their "junker," but Kenobi was confident that Skywalker would be able to pilot his "bucket of bolts" through hyperspace. The Republic was eventually able to defeat the Confederate forces. Amidst the settling dust, Rex expressed his frustration with the poorly-handled operation to Cody. Rex was still devastated with the loss of Torrent Company, but Cody stated that the battle had not been in vain, as Skywalker and Tano had reached Tatooine with the Huttlet still alive. Rex later accompanied Jedi Masters Yoda and Kenobi to Tatooine to retrieve Skywalker and Tano, who had successfully returned Rotta to his father and established a treaty with the Hutts. Skywalker and Tano wanted to hear all the details of the rest of the battle, and although Rex was still distressed from the loss of so many of his men, he agreed. Although 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

As the war continued, Skywalker, Tano, and Rex returned to the galactic capital of Coruscant. Eventually, General Skywalker was given command of his own battle group to defend the planet Bothawui, which the Jedi High Council had learned to be Confederate General Grievous's newest target. Kenobi, who had been injured in a terrorist bombing, was unable to participate in the mission. However, the Jedi Master knew that Skywalker would want Rex and the 501st Legion for his strike force, and Rex and his men were put on standby. Once the three Venator-class Star Destroyers making up Skywalker's fleet&mdash;the Resolute, Pioneer, and Dauntless&mdash;had arrived from the Allanteen Six shipyards, Skywalker took the Resolute as his flagship, and Admiral Yularen was assigned to be the ranking Republic officer aboard the cruiser. Rex got his men settled on the Star Destroyer and enjoyed a brief reunion with Skywalker and Tano, who were both pleased that the clone captain had been assigned to their task force. After preparations for their departure had been completed, Skywalker's fleet left Coruscant for the Both system. En route to Bothawui, the Republic Star Destroyers were pursued by Grievous and his force of four Munificent-class frigates. Skywalker engaged Grievous multiple times in open space before taking a direct hyperspace route to Bothawui.

The Resolute, Pioneer, and Redeemer arrived at Bothawui ahead of Grievous, but Skywalker, Tano, and Rex soon learned from General Kenobi that Grievous had only delayed his pursuit of them to pick up two more frigates and overwhelm Republic forces on the planet Falleen. Although outnumbered two-to-one in vessels, Skywalker was intent on protecting Bothawui from the Separatists' grip. Skywalker deployed Rex and a detachment of AT-TE walkers to the asteroid belt surrounding the gas giant of Bothawui Prime. The walkers would be able to outflank Grievous once he and his fleet had passed through the asteroids. After the six Confederate frigates had 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 unshielded rears. The ambush was all the more successful because the unsuspecting Grievous had previously diverted all of his frigates' power to the forward shields instead of those at the backs.

The Resolute, Pioneer, and Dauntless released a barrage of laser fire at the Confederate ships, prompting Grievous to flee his crumbling fleet in his personal starfighter, Soulless One. While piloting his Delta-7B starfighter in pursuit of Grievous, Skywalker's craft was hit by flying debris and exploded, veering toward the asteroid belt. Rex managed to rescue Skywalker, but was unable to save R2-D2, who had been serving as the Jedi General's astromech droid on board 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 his three Star Destroyers could use modifications, Skywalker took his cruisers back to the shipyards where they had been manufactured. Eventually, Kenobi contacted Skywalker and Tano at the shipyards and reported that Republic Intelligence had confirmed the existence of a Confederate listening post that had been intercepting Republic transmissions. Kenobi gave Skywalker the new mission of finding the station before it continued to prove a threat to the Grand Army's war operations.

Skywalker elected to undertake the sweeps of space suspected of Confederate activity while the rest of his forces concentrated on a more central path. Rex questioned Skywalker whether he was sure that he wanted to scout ahead alone, but Skywalker was certain that more than one fighter would attract too much attention from the Separatists. Taking replacement astromech droid R3-S6 with him, Skywalker departed in his retrieved Delta-7B fighter with a hyperspace docking ring, unaware that R3-S6 was a spy working for Grievous. After Skywalker had begun his mission, Tano received a signal from the homing beacon of her Master's fighter. The alarmed Padawan ordered Rex to gather as many men as he could to mount a rescue mission. Tano, Rex, and a squad of troopers soon arrived in the Twilight to reinforce Skywalker against a pair of opposing Confederate Munificent-class frigates&mdash;under the command of General Grievous&mdash;and a squadron of Vulture droids. With his hyperdrive docking ring disabled, Skywalker piloted his fighter into the Twilight cargo bay to retreat with the Republic force. Tano maneuvered the Twilight right between the wings of the two enemy frigates. Once the ship was clear, Rex engaged the Twilight hyperdrive, and the Jedi and clones escaped from Grievous.

A short while later, R2-D2, who had been captured by the Trandoshan scavenger Gha Nachkt, managed to get a message through to the Twilight. Rex tracked the droid to Ruusan 2, a moon of the planet Ruusan. The Twilight arrived over the moon, where the Republic squad 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 rescue-and-destroy operation. During preparations for their departure, Tano informed Rex that he would be carrying R3-S6 to the station, a task that Rex was not enthusiastic about undertaking. The Twilight entered the gassy atmosphere of the moon, and Skywalker, Tano, Rex, and four other troopers used the Force and JT-12 jetpacks, respectively, to safely land on the station. Upon landing with the heavy R3-S6 in his arms, Rex insisted that he would never lug an astromech droid around again.

Skywalker cut a hole in the roof of the station, and the Jedi and clones entered the listening post. Rex and another trooper destroyed two B1 battle droid guards in their path and proceeded with the rest of their unit to a computer terminal, from which R3-S6 accessed the station's building schematics and relayed them holographically to the squad. Rex briefed the squad on the location of the 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 reported to Skywalker that an alarm had triggered the entrance's ray shield. 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. Tano admonished Rex, telling him to be patient. In actuality, however, R3-S6 was simply stalling to give the approaching battle droids time to ambush the Republic squad.

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. R3-S6 activated the reactor room's secondary door, sealing the Jedi and clones off from the reactors. B2 super battle droids soon arrived and attacked the Republic troops. Caught in a crossfire, Tano ordered Rex to utilize EMP grenades&mdash;nicknamed "droid poppers"&mdash;against their adversaries. Rex complied and tossed a grenade in both directions, eliminating the battle droids. However, the Republic squad's troubles were not over. Grievous himself arrived and confronted the squad, briefly exchanging lightsaber blows with Tano before batting her aside and attacking Rex and the clone troopers. The five clones defended themselves with their blasters but were knocked aside, and all except Rex and trooper Denal were killed. As Grievous prepared to kill the unconscious Rex, Tano intervened in time to stop the general's death blow with her own lightsaber. Tano continued to distract Grievous, dueling the cyborg and drawing him into a storage room.

Rex and Denal eventually regained consciousness, and the former contacted Tano via comlink. The Padawan ordered the clone captain to complete the mission while she fought Grievous by herself. Although Rex protested to Tano's plan, he complied, and he and Denal were able to enter the reactor room and plant the explosives. The two troopers then departed to rendezvous with Skywalker and the Twilight at the station's landing bay. Upon meeting with the two clones, Skywalker became alarmed when he learned from Rex that Tano had engaged Grievous alone. As Rex and Denal headed toward the exit to lead Skywalker to his Padawan with the Twilight clone pilot as backup, R3-S6 closed the blast doors and sealed all exits from the hangar. The astromech droid also activated several Vulture droids hanging from the roof, revealing his secret loyalties to Grievous and the Separatists. Surrounded by Vulture droids on one side and super battle droids on the other, Skywalker and the clones were attacked on both sides. Rex and the troopers ran for cover behind several crates and returned laser shots at the battle droids while Skywalker deflected the droids' lasers with his lightsaber.

Skywalker ordered Rex to activate the explosives planted at the reactors, despite the fact that the entire squad was still in the station, as noted by Rex. The clone captain detonated the charges, crippling Skytop Station's reactors and beginning its gravity-pulled descent into Ruusan 2's atmosphere. In the continuing firefight, Skywalker sent R2-D2 to open the hangar door from a terminal on the station's exterior. Tano eventually returned from her duel with Grievous and made her entrance by eliminating two of the Vulture droids. Rex noticed several fuel cells next to the crates, and Skywalker used the Force to hurtle one of them at the droids. Rex placed a well-aimed shot on the cell, and in the resulting explosion, all of the remaining battle droids were eliminated. R2-D2 was able to open the hangar door, and after the Jedi and clones had escaped the doomed station aboard the Twilight, Skywalker departed in his Delta-7B fighter to retrieve his astromech droid.

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

Some 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 Navy Captain Gilad Pellaeon's newly-refitted assault ship, Leveler, in the Dantus sector. After sending his compliments to Pellaeon, whom he was acquainted with, and requesting to join Leveler testing session, Rex departed with Tano, Sergeant Coric, and six clone troopers new to Torrent Company&mdash;Ross, Boro, Joc, Hil, Vere, and Ince. 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. Rex avoided answering the question directly, and because the captain had chosen that he did not want to know the reasons behind Skywalker's actions, he did not appear as lying when Tano attempted to sense his true beliefs through the Force. Rex himself was more concerned with his troopers, worrying that he would have to make use of the inconsiderate tally sensor to tell the six rookies apart because they lacked the unique personalities that normally made clones identifiable from one another. After arriving aboard Leveler and meeting with Pellaeon, Rex and his men were forced to stand back and watch as Tano argued with Pellaeon over the appropriateness of her rather revealing choice of clothing, a short-lived debate that Tano lost.

Waiting for Tano to change into a navy suit given to her by Pellaeon, Rex exchanged a few words with Pellaeon in a brief reunion. Once Tano had put on a suitable uniform, 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 for the Bolo-ball final to support the Sullustan Bylluran Athletic team. Rex and Pellaeon began to discuss Leveler new weapons until they were cut off by an alert that a flotilla of Confederate ships had exited hyperspace in the nearby Fath sector. Tano sensed a disturbance in the Force, which, at Rex's advice, Pellaeon took as an "early warning." Despite the fact that the Separatist activity could result in nothing, Rex took precautions and departed to round up his men in case they would be needed.

On his way back to his detachment's quarters, Rex learned from Lieutenant Meriones that there were more Separatist ships active than the original six that Leveler had tracked. Returning to Torrent Company's barracks, Rex almost instantly came to regret his own novelty haircut for its undignified appearance at the sight of his men's normal black haircuts, resolving to shave his hair back to its normal cut when he got the chance. Rex reported the situation to Tano and the troopers and stated that Leveler was proceeding to observe the enemy activity in stealth mode. Joc's inquiries into Pellaeon's private life eventually 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 and discreetly giving Tano permission to leave the barracks. After Tano had departed to check out the ops room, Rex admonished 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.

Rex led his men down to the hangar deck to undertake fifteen circuits and then familiarize themselves with all the planets of the Fath system, where Leveler was headed to more closely keep watch on the Separatists, in an attempt to keep himself and the other clone troopers busy and focused. Rex also contacted Skywalker and informed him of Leveler diversion to the Fath system. Despite Rex's belief that the Jedi General's involvement was unnecessary, Skywalker set off to rendezvous with Leveler. Pellaeon's cruiser itself soon became host to the Altisian Jedi sect, which requested permission to dock its freighter, Wookiee Gunner, to Leveler on the grounds of receiving a discress signal from a Republic agent on the nearby planet of 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 resolved to rendezvous with Wookiee Gunner and transfer several of the Altisian Jedi over for the hostage extraction, an operation that Rex promised his troops for in the absence of embarked troops.

The mission was further complicated with Republic Intelligence's identification of Hallena Devis to be the captive operative, forcing Pellaeon to reveal Devis to be "a very good friend" of his. Master Djinn Altis, Callista Masana, and Geith Eris of the Jedi sect boarded Leveler and convened with Pellaeon, Rex, Tano, and Torrent Company in the assault ship's meeting room to formulate a plan for the operation. When Pellaeon alluded to his plans of participating in the mission, Rex objected, citing that it was his own responsibility and that of Torrent Company in the absence of embarked troops. Rex also noted his experience in hostage extractions and stated his intentions to avoid repeating a situation similar to that of the dire Battle of Teth. Without reinforcements, Rex knew that all they could hope for was a successful rescue and not a full-scale fight against the Separatists. Meanwhile, Eris and Masana wanted to undertake the recon of JanFathal's capital of Athar themselves, as the very production of clones for the Grand Army of the Republic went against their beliefs. Despite the two Jedi's wishes to avoid having the clones participate, Rex refused and stated that it was his job. With the other clones' insistence, the Altisian Jedi finally complied with the troopers' wishes. While the anonymous-appearing replenishment shuttle that the group would be taking to JanFathal was prepared, Rex conferred with Pellaeon on the craft's cloaking procedure as well as the Jedi themselves.

Rex defended Tano when Pellaeon expressed doubt in her abilities on account of her age. Rex refused to use civilian clothing for the mission, stating that he would "rather trade armor advantages against stealth." He also comforted Pellaeon and was confident that his squad would be able to rescue Devis. Using a stylus that the Intelligence agent had given to Pellaeon, Altis, Eris, Masana, and Tano were able to get a "fix" on her life signature and confirm that she was alive. With the Sullustan sensor technician Benb finished with outfitting the shuttle, the clones and four Jedi boarded the craft. Sergeant Coric piloted the ship to Athar, and during the flight, Rex noted that the operation was only "half as insane" as that of Teth. Reminded by Coric of the necessity of keeping Tano&mdash;who had become unnerved with meeting the controversial Altisian Jedi&mdash;focused on the mission at hand and not on the other Jedi's opposing beliefs, Rex conferred with her and confirmed that she was coping well.

Masana apologized for putting Rex in an "awkward position," and though she struck Rex as sensible, Masana's explanation of the Altisian Jedi eventually provoked Tano&mdash;still uncomfortable with the Jedi sect&mdash;to call out Rex's apparent casualty with the ongoing "Jedi politics." Rex dispelled the conversation and conferred with his rookie troopers over their private circuit. Rex reassured and took pity on the new 501st inductees, as they had been taught on Kamino that the Jedi were "sorted" instead of unstable, as they currently were. Coric took the shuttle to bypass a Separatist landing craft, and upon entering JanFathal's atmosphere, he immediately headed for Athar to avoid calling attention to the extraction squad. 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. Despite Rex's beliefs, Coric was able to safely land the shuttle. Boro and Joc jumped out and took defensive positions around the ship, allowing Rex and the others to take cover in a nearby building.

Inside the building, Altis borrowed Ross's helmet to observe the recordings of a remote that he moved with the Force, and Rex savored the "incongruous sight" of a Jedi Master with the head of a clone trooper. Shortly thereafter, Rex, Tano, and Masana reconnoitered the vicinity of the building where Devis was being held by the Separatist-allied rebels. Rex formulated 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 separately infiltrate the Republic Intelligence agent's prison. Masana signaled the rest of the squad to join them, and Rex dispatched her and Tano to keep a lookout for any approaching battle droids and prevent the Separatists from interfering with the operation. Rex sent Altis with Joc, Ince, and Ross to cover the exit while he himself led the others to scale the wall and enter the building via the roof. Rex explained to Altis that the objective was to incapacitate the hostage-takers&mdash;before they had a chance to kill Devis or detonate any devices&mdash;and rescue the captive agent as quickly as possible. Altis resolved to draw the attention of the agent's captors from the door, and Rex took his squad and Eris to the roof.

Once Altis had distracted rebels Merish Hath, Shil Kaval, and Varti, Rex and his men set off explosives and landed beside the Jedi. After Altis had incapacitated Hath, Rex and two clones smashed through the door of the room where Devis was being held. Rex pointed his blaster at Varti's head, and the fighter in turn held his own gun to Devis's temple. Though Varti stalled for time, Rex surprised everyone by discharging his own blaster, killing the old man and freeing Devis. Completely calm despite his near-mindless kill, Rex used a vibroblade from his gauntlet to sever Devis's cuffs and ushered her toward the exit. When the protesting Devis stopped and attempted to retrieve her comlink from the badly-wounded Kaval, Rex picked her up and almost threw her to Hil. After Devis had been moved to safety, the building began to crumble, and Altis, Rex, Vere, and Boro charged out of the structure. Rex confirmed that Ince was taking Devis to Coric's shuttle before joining the fight against the approaching army of battle droids. In the ensuing battle, however, 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, to which Boro complied. 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, the Jedi focused through the Force, waiting for the civilians in the area to flee from the crumbling buildings before toppling a nearby building onto the droids and blocking their path with rubble. Rex contacted Coric, who unexpectedly arrived with the shuttle to extract the rest of the group. Leading his troops back to the craft, Rex learned that at Devis's insistence, Coric had gone back on his orders of waiting "only for the agent and Jedi" and had instead decided to come back for the squad. Despite Coric's disobedience, Rex was grateful for his actions. With Vere's time expired, Rex resolved to keep his anger with the loss contained so that it would serve as fuel for the job at hand, intending to let it go later when no one would see him break down. The shuttle pulled out of the area shortly before the battle droids caught up to the Jedi and clones.

En route to Leveler, Devis thanked Rex for his men's efforts, and although Rex accepted her gratitude, he avoided engaging with her in the "conversation waiting to happen" because he felt he was not the man to have it. Rex noted that Ross, Boro, Joc, Hil, and Ince had fallen absolutely silent and deduced that they had opened up a private comlink frequency. Rex respected their privacy and avoided intruding on it, knowing that they had to have some time to discuss matters&mdash;among them, the hard-to-take loss of Vere&mdash;without his interference. Rex conveyed his congratulations to his men on the successful rescue, noting that JanFathal was lost to the Republic before cursing himself for "tempting fate." Coric was soon contacted by Skywalker and received word that the Jedi was arriving to help the squad. Leveler, meanwhile, was attacked by the Separatist destroyer Reaper and forced to flee to hyperspace before the shuttle could dock to it, leaving the Jedi and clones to fend for themselves. With their main source of life support unavailable, Rex ordered Coric to deactivate all of their craft's nonessential systems.

Boro calculated that with their limited oxygen supply, they would only be able to make it halfway&mdash;perhaps closer if everyone reduced their oxygen consumption&mdash;to the Kemla Yard shipyard where Leveler had been outfitted, the closest Republic-allied location. The squad instead elected to instead head back to Athar and mount a last stand. Shortly afterward, Skywalker arrived in the system aboard a V-19 Torrent fighter and contacted Rex. Rex updated his Jedi General on the situation, and the mixed squad of Altisian Jedi and Torrent Company rendezvoused with Skywalker in JanFathal's occupied capital. There, Skywalker was introduced to the rookie clones and the Altisian Jedi and told the squad that he had seen at least three of the Separatists' hyperdrive-equipped and life support–outfitted CR-20 troop carriers that could be used to escape JanFathal, lifting the clones' spirits. However, Rex winced when Skywalker learned that Masana and Eris were engaged. Ince tossed a remote into the nearby Separatist lines and gleaned images of Confederate transports deploying both droids and organic troops. Altis, meanwhile, received word from Ash Jarvee, a member of his Jedi sect back with Wookiee Gunner, that Leveler was returning to the system from a miscalculated hyperspace jump.

Skywalker sent Masana, Rex, and the clone troopers to a road bridge above a sports field mapped out on Ince's datapad from which to wait for himself and the other Jedi to work around from the other direction and seize the CR-20. The clones would then provide covering fire until the ship lifted off, at which point they would embark the troop carrier. Once Masana, Rex, and the clones were in position, Skywalker, Tano, Altis, Eris, and Devis commandeered the CR-20 and proceeded to rescue the troopers. However, Ince was injured in the battle against the droids and was treated by Hil. A Vulture droid soon approached and fired at the paving behind the group, but Masana deflected the falling debris with the Force and edged over to take care of 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 in walking mode, and Ross got the droid's attention while Rex himself fired his rappel line at the droid, tangling its legs in the cord and pulling himself toward his mechanical adversary. Rex grimly clung onto one of the droid's legs, and the Vulture droid spun in an attempt to throw him off, becoming more entangled in the line in the process. Rex thrust his blaster under the droid's "chin" and released a barrage of laser fire, and Ross's blasting of one of the wing joints disabled the droid. The two troopers escaped to the CR-20, which promptly made for Leveler. While Ince was stabilized, the visibly battle-weary Rex manned one of the troop carrier's blaster cannons and was eventually joined by Tano, who took control the other turret.

The CR-20 skidded into one of Leveler hangars, and Ince was immediately taken to the warship's medbay. With Force-controlled aide from the Altisian Jedi, Leveler fired at the approaching Confederate ships with its concussion missiles and escaped to hyperspace, heading for Kemla Yard to rendezvous with Wookiee Gunner and drop the Altisian Jedi off. Rex, his men, and Devis arrived to support Ince in his cubicle in the medbay, where Rex grimly alternated between monitoring his injured comrade's biosigns and slowly pacing along the perimeter of the treatment bay. Ince's kidneys began to fail, and when the trooper finally died from blood loss, the furious Rex stormed out of the medbay and took refuge in the mess hall. Tano found the upset clone captain there and discussed the Altisian Jedi's views of the clone army with him, and the conversation soon put both Rex's and Tano's beliefs in question. Rex maintained that he and the rest of his clone brethren in the Grand Army fought in the war because they were making the best of a situation that "they did not choose." Although Rex was able to finally find stability instead of having to avoid providing outright lies as answers to Tano's questions, Tano herself found it difficult to solidify her own beliefs.

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

With several recent 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. The mission fell to Skywalker, Kenobi, and Rex, who were presented with the problem of determining the exact location of the shipyards and infiltrating Gwori itself&mdash;the planet was protected by a Separatist blockade and a radiation beam that eradicated all life forms entering the world. To counter the beam, Skywalker devised a plan for a small strike force to be frozen in carbonite and infiltrate the planet. R2-D2 would pilot the ship 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 lead a Republic squadron to eliminate the facility. Skywalker and Kenobi assembled their team at carbonite freezing plant CT-642. Though Rex expressed his concern that the squad might be susceptible to hibernation sickness, Skywalker stated 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.

R2-D2 took freighter VX-391 to Gwori with the carbonite-encased strike team. After the blockade's battle droids discovered that the freighter was unregistered, R2-D2 was forced to release the task force and escape the ship before it was shot down. The astromech droid freed Tano from her carbonite slab, and she in turn released the rest of the squad. Finding 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. Tano and the troopers eliminated the station's battle droid guards, and Tano contacted Koon, Tiin, and Admiral Yularen, who were waiting in the Moskk system, with the shipyards' coordinates. Before the infiltration team's escape 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, and their squad fled shortly before Juhm remotely destroyed the station.

Tano informed Skywalker and Kenobi of the situation, and Skywalker told his Padawan to find cover while he and Kenobi infiltrated the shipyards. Out on Gwori's plains, Tano, Rex, and the clones were attacked by several B2-RP battle droids. After engaging the battle droids, Tano, Rex, R2-D2, and the two clones took refuge inside a nearby cave. The group was attacked by a large lizard-like creature, and one of the clones was killed before Tano could eliminate the beast. As time went by, the extended lack of communication from Skywalker and Kenobi prompted Tano to deduce that the pair was in trouble. Tano decided that it was time to "alter" Skywalker's orders to stay concealed, and although Rex voiced his doubt with disobeying their orders, he left the cave with Tano and the other trooper. However, Overseer Juhm and a squad of B2 super battle droids suddenly ambushed the squad, killing the other trooper. Presented with the choice of either surrendering or being shot down, Tano and Rex decided to comply with Juhm's demands. The two were taken captive and ushered away, leaving R2-D2 in the cave.

As night fell, Juhm attached Tano and Rex to electrically-charged frames alongside Skywalker and Kenobi, who had been captured at the shipyards. Juhm left IG-100 MagnaGuards to guard Rex and the Jedi from spiders and ensure that they stayed alive as a "reminder" to the shipyards' slaves of his own superiority. The four were tortured and electrocuted in turn, and 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 shortly arrived, cutting Skywalker, Tano, Kenobi, and Rex from their frames. Proceeding to the shipyards, the four convinced Juhm's slaves to liberate themselves from their servitude to the Separatist overseer. At dawn, Skywalker, Tano, Kenobi, and Rex stole one of the shipyards' near-completed Munificent-class frigate to escape the destruction that was about to befall the facility at the hands of Koon and Tiin, who arrived to eliminate the shipyards with Hunter Squadron.

The Republic bombers dropped their munitions on the construction facility just as the frigate carrying the Jedi, Rex, and the ex-slaves lifted off. Using the ship's tractor beam, Skywalker retrieved trooper Toomer, who was still encased in carbonite after 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 frigate's passengers were saved when Koon and Tiin intervened, destroying the scan gate. The two Jedi Masters hitched a ride on the vessel, as their hyperdrive rings had been destroyed, and the frigate escaped the 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 told the disappointed trooper that there would be "plenty more fighting to come."

Different battlefields
"Try and keep them out of trouble, Captain.''" "''Sorry, sir. I can't make any promises where those two are concerned."

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

While liberating the planet Queel from the Confederacy alongside Skywalker, Kenobi, and Tano, Rex accompanied Tano 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 to traverse the river. 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. Shortly thereafter, Commander Cody informed Skywalker and Kenobi that there was an incoming message from the Jedi Temple, and Rex returned to the Republic's forward command post with the three Jedi. Holographically conferring 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 stay on Queel and finish the battle.

Rex went with Skywalker and Tano in the Twilight to Mon Gazza, and Skywalker left to find Messo while Tano and Rex stayed to secure the freighter. Changing out of his usual clone trooper armor, Rex donned a heavily covered-up disguise and accompanied Tano to find her Master, who had located the Confederate agent. When Skywalker confronted his target in a podracing arena, Messo had already transferred the data file. With his blaster shots rebounded at him by Skywalker, Messo fell into the arena and was hit and killed by a podracer before he could reveal any more information. Tano and Rex joined Skywalker in the stands to watch the race, and Skywalker informed his Padawan that he had entered her into the race to get closer to the other racers, as he believed that Messo's contact belonged to one of the racing teams. Skywalker, Rex, and R2-D2 acted as Tano's pit crew, and the group proceeded to the podracing stalls.

While Skywalker outfitted Tano's pod in their stall, the Padawan reported that Jedi intelligence had confirmed that several enemy espionage events had coincided with the racing circuit being in the same system. Present for each of the events was skilled podracer Kidd Kareen and his racing team. Rex watched as Skywalker taught Tano the pod's basic controls before Kareen himself came over to talk with the two disguised Jedi. After Kareen's crew left, Tano kept the podracer occupied while Skywalker went to take a look around his stall, putting Rex and R2-D2 on lookout. However, Maxus&mdash;a close friend of Kareen and a member of his crew&mdash;caught Skywalker snooping around. As a fistfight began between Kareen's crew and Skywalker, Rex joined the fray. Tano and Kareen eventually returned, halting the fight, and Tano was forced to apologize to Kareen. With the second qualifying race at hand, Tano, Skywalker, Rex, and R2-D2 quickly left, as the Padawan was scheduled to make her debut in the race. Rex and Skywalker watched Tano safely maneuver through the course via R2-D2's hololink.

As Tano approached the finish line, however, another podracer rammed her from behind. Skywalker and Rex immediately rushed to Tano's aid and helped her out of the debris of her destroyed podracer. Kareen arrived, offering to loan Tano one of his spare podracers, and Tano 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. The pair learned that Maxus was working for Confederate Head of State Count Dooku, who arranged to send an agent to collect the datachip from Maxus the following day. During Tano's second race alongside Kareen and Maxus that day, Skywalker and Rex noticed Maxus picking up the datachip from the podracing pits, and the two immediately gave pursuit. Maxus escaped in his podracer, and the rest of Kareen's crew engaged Skywalker and Rex in a blaster fight. Skywalker stole a speeder bike and departed to help his Padawan, leaving Rex and R2-D2 to finish off the rest of the podracers. Tano was saved by Kareen from being killed by Maxus, and she and Skywalker were able to Force-crush the datachip, preventing Asajj Ventress from intercepting it. With their mission a success, the Republic group said goodbye to Kareen and boarded the Twilight, reporting the operation's completion to Kenobi as they departed Mon Gazza.

During an attack on Trade Federation forces over the Bothan colony of Kothlis, Rex served as the gunner of Tano's BTL-B Y-wing starfighter. Skywalker, Kenobi, and Tano engaged the Vulture droids that were deployed from a Federation Lucrehulk-class Droid Control Ship, and Tano assaulted the control ship with torpedoes. As the vessel was eliminated, Rex commented that its destruction was a beautiful sight. The Trade Federation Dreadnaught-class heavy cruisers were forced to flee, and Tano and Rex were able to secure a victory for the Republic. 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 Defrandi tribe. En route to Taloraan aboard the Resolute, Rex conferred with Tano on the diplomacy that she would be engaging in within the next few days. Although Tano found diplomatic negotiations boring, Rex stated that he respected them as a kind of fighting that he "was not trained for." While the three Jedi left for the world's capital, Taloraan City, in a Nu-class shuttle, Rex remained onboard the Resolute with Admiral Yularen to regularly check in with the Jedi. Unbeknownst to the Republic, however, Defrandi Magister Orlin Denache had secretly allied himself with Count Dooku and the Confederacy and was housing Separatist battle droids on Taloraan.

Eventually, Admiral Yularen was warned by the Jedi&mdash;who had discovered the Separatist presence in Taloraan City&mdash;that the Resolute was heading into a trap. The Resolute activated its deflector shields in time to deflect fire from Confederate Captain Canteval's Munificent-class frigate. While the Resolute engaged the enemy vessel, Yularen sent Rex and a clone detachment to rescue the Jedi, whose shuttle had been destroyed. After landing with several LAAT/i gunships in Taloraan City, Rex and his men fell under fire from the Separatist-allied Defrandi taking cover behind several cargo boxes. Although Rex ordered his men to find cover, the firefight was stopped when Denache's Republic-loyal emissary, Sech Govlinder, led the rest of the Defrandi people to defeat the Separatists. The Jedi were able to establish a treaty with the Defrandi and their rival tribe, the Wind Raiders, thanks in part to Tano's personal involvement in the matter. Rex inquired after Tano's views on diplomacy, to which the Padawan replied that they were not as boring as she had originally thought.

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 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. When several Armored Assault Tanks approached the group, Rex used a rocket launcher at the tanks, destroying them. As the Republic secured the majority of the city, the Confederate commander, Xerius Ugg, requested an audience with Kenobi. Kenobi left to negotiate with their adversary, leaving his comlink open so that Skywalker, Tano, and Rex could listen in on the deliberations. The three learned that Ugg had planted multiple thermal bombs around the city as leverage against the Republic forces, and the Separatist commander demanded the Jedi's surrender. While Kenobi fought Ugg to stall for time, Skywalker and Tano went to disable the explosives and sever Ugg's bargaining chips.

As Skywalker and Tano deactivated one of the bombs, a sniper droideka rained down laser fire at the pair. Rex intervened, using a sniper rifle to eliminate the droid. With Ugg's leverage against the Republic compromised, the Jedi were able to defeat the Separatist commander. However, the Jedi found that all of Kiros's Togrutan population had disappeared. Rex and the three Jedi returned to the Republic fleet surrounding Kiros, and Skywalker ordered Rex to recall the troops from the surface. Rex and a squad of troopers then accompanied Skywalker, Tano, and Kenobi to investigate a lead on the population's disappearance that concerned the Zygerrian system&mdash;home of the Zygerrians, who had once been slavers before the Jedi intervened and supposedly halted their slave trade. The Republic squad took the Twilight to the remains of the Shi'kar homeworld to gather more information about the disappeared Togrutas and encountered the Zygerrian slaver vessel Fate's Hand amidst the asteroids.

Pretending to be slavers themselves, Skywalker, Tano, and Kenobi boarded the Fate's Hand and conferred with the ship's captain, Onyx, while Rex and several troopers hid behind several nearby crates as backup. The Jedi eventually gave up the ruse and drew their lightsabers, signaling Rex and the clones to forsake their cover. In the ensuing firefight, Skywalker led Tano, Rex, and several other troopers to commandeer the Fate's Hand. However, more Zygerrians appeared from the ship's compartments, catching the Jedi and clones in a crossfire. A Zygerrian fired a rocket at the Republic squad, damaging the seal between the Twilight and Fate's Hand. Rex reached out to Tano, telling her that the seal was failing, but Tano intentionally sealed herself onboard the Zygerrian freighter, with Skywalker, Kenobi, Rex, and several Zygerrians on the Twilight. A dismayed Rex reported the Padawan's actions to Skywalker and Kenobi, who deduced that she was simply attempting to infiltrate the ship by acting as a hostage. Cut off from the Fate's Hand, Rex secured the docking clamps of the Twilight to ensure that they would not be separated from the Zygerrian craft.

In an attempt to force the Twilight away from his ship, Captain Onyx took his freighter through the asteroid belt, and the Twilight bottom stabilizer was compromised from a collision with a rock. Using the Twilight laser cannon, Skywalker disabled the engines of the Fate's Hand. Shortly thereafter, the Jedi were contacted by Tano, who, at Kenobi's direction, was able to unlock the rear maintenance airlock of the Fate's Hand before she was discovered by Onyx. Intending to rescue Tano, Rex and another trooper accompanied Skywalker and Kenobi into space to board the Fate's Hand. However, the four were confronted by a Blixus creature that Onyx released. Releasing laser fire at the creature, Rex discovered that it was impervious to blaster fire. The Blixus quickly killed the other clone and captured the two Jedi, but Skywalker impaled the Blixus with his lightsaber, halting its rampage. Rex boarded the Fate's Hand with Skywalker and Kenobi 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 was to be sold into slavery. On Kenobi's orders, Rex took Onyx to imprison him with the rest of his crew on the Twilight.

The Fate's Hand was repaired, and the Jedi and Rex took the freighter to the Zygerrian system in an attempt 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 in disguises to avoid standing out. Meanwhile, 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 almost compromised their cover stories, and Skywalker sent his Padawan back to the ship. Tano then joined Kenobi and Rex in serving as backup for Skywalker during his confrontation with several Zygerrian guards. Upon Zygerrian Queen Miraj Scintel's request for an audience with Skywalker, Rex, Kenobi, and Tano followed Skywalker to the Zygerrian Royal Palace. Watching Skywalker enter the palace, the three went to investigate the catacombs below the building. 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 Jedi and Rex 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. Fleeing with Tano aboard her mount, Rex returned laser fire at the pursing guards airborne on flying creatures. Skywalker soon contacted Tano and ordered her to go to the palace, as he required his "merchandise" to make Queel Scintel believe his cover story. The four split up, planning to meet back at the Fate's Hand. While Tano and Rex managed to return to the ship, however, Kenobi and Governor 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 to serve as backup for Skywalker and Tano at the auction. The three were met with a grim surprise when Roshti and Kenobi were brought into the arena. As Scintel ordered Skywalker to whip Kenobi in order to prove that "he had what it [took] to be a slaver," Skywalker signaled to Rex to ambush the Zygerrian slavers. Swinging from a cable, Rex rained laser fire down on the Zygerrian guards in the arena, allowing Tano to retrieve her own 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 a Zygerrian fired a rocket from above that knocked Rex unconscious. The three Jedi were subdued as well, 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 the other captured Jedi and Rex served as the Queen's leverage over Skywalker.

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 the cost of growing isolation from the Togrutas, whom the Zygerrians put to torture if Kenobi refused to submit. While working at a wheel alongside the Togrutas, Kenobi and Rex conversed on the fact that the "poor souls" had lost most everything valuable to them, including their freedom. However, Rex helped Kenobi 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 their "training" 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 slavery to Scintel, Skywalker and Tano arrived on Kadavo with a clone strike force to rescue Kenobi, Rex, and the Togrutas. 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 population to the volcano. With the arrival of Separatist aerial forces led by General Grievous and Dark Acolyte Asajj Ventress, Skywalker and Tano were forced to stop cutting through the door, and the Keeper ordered them to surrender. Instead of aiding the Zygerrians, however, the Vulture droid starfighters began to attack the facility's supports to eliminate the Togrutan population and hide the Confederacy's involvement in the slavery affair.

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. The Confederate fleet retreated, and from atop Skywalker's stolen freighter, the Jedi used the Force to pull the Togrutas aboard the ship. Although Ventress's ship, the Trident, assaulted the freighter, Rex fired a rocket at the Dark Acolyte's ship. The arrival of Master 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 captive, the Jedi and clones prepared to return the Togrutas to their home. As Rex was about to detonate charges planted in the processing hub, Supreme Chancellor Palpatine contacted the Jedi, ordering the facility to be "left intact for Republic use at a later date." The Jedi could see no use of maintaining the facility, and at their advisement, Rex proceeded with eradicating the facility. On Kiros, Rex helped to train the Togrutas in blaster combat at their own request, and the pacifist Governor Roshti noted that they were being forced to be warriors "whether they wished to or not."

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

Assigned to inspect Republic tracking stations with Commander Cody, Rex and the clone commander took the captain's Nu-class attack shuttle, the Obex, to a tracking station in the Pastil system. Arriving on the planet, the two began inspections of the outpost, and Rex 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 troopers to find "Rodent." The rookie clones were unaware of Rex's suspicions and at first believed the clone captain to be crazy. When Rex found the droid and blasted its body, however, the droid's wheels activated of their own accord and fled, a feature not present in regular MSE droids.
 * FIT IN RISING MALEVOLENCE INFO SOMEWHERE

The troopers eliminated three of the wheels, and the fourth wheel spun toward a grate. Stripe destroyed the last wheel with a thermal detonator, and the explosion caused damage to the hallway. Amused, Rex told the troops to "clean the mess up" before leaving with Cody. Continuing their assignment, Rex and Cody reported their successful inspection to Generals Skywalker and Kenobi aboard the Resolute and proceeded to a base in the Rishi system. However, the clone officers were unaware that the base had been overrun by Confederate BX-series droid commandos. Cody contacted the base, and a droid commando posing as a clone trooper answered the transmission. Rex believed that something was amiss, but nevertheless, the two clones continued toward the outpost. Cody put the clone captain in charge of the inspection. Upon arrival, Rex noted the base's sloppy absence of a deck officer on duty. The two troopers were greeted by a droid commando sporting clone trooper armor.

When the clone survivors of the Separatist assault launched a droid attack flare, Rex promptly shot their "trooper" greeter in the head. At first, Cody was shocked with the captain's behavior, but after Rex removed the helmet of the clone, the disabled droid commando was revealed. Confederate droids appeared and ambushed the pair, and the two clones exchanged fire with their adversaries while using several crates as cover. The droid commandos tossed a set of thermal detonators at the Obex, and the two troopers jumped off the platform to avoid the explosion. With their only means of escape compromised, Rex and Cody used the cables in their blasters to descend to the ground below. The two came across the three survivors of the droid assault &mdash;rookie troopers CT-26-6958, CT-27-5555, and CT-26-1409, nicknamed "Hevy," "Fives," and "Echo" respectively &mdash;and Rex ordered the clones to take their sunbonnets off to verify that they were clones. After the three troopers had done so, a Rishi eel appeared, and Rex impressed the three rookies with his marksmanship by killing the eel with a single blaster shot to its eye.

The clone captain deemed Echo, Hevy, and Fives "shinies," a derogatory term for the troopers' spotless armor that had not yet seen action in battle. Rex put a handprint of Rishi eel blood on Echo's armor and responded to Hevy's fighting spirit by stating that "there was hope for them yet." The two clone officers offered their own DC-15S blasters to the rookie troopers, and the clone captain devised a plan to infiltrate the droid-held base. Posing as commando droid 26 in clone armor, Rex fooled the droid Units 07, 08, and 09, using a decapitated droid head as "visual verification". Although Cody doubted that the tactic would work, the droid commandos admitted Rex entry to the station. As soon as the blast doors opened, the squad of troopers eliminated the guards. Taking point, Rex led the clones to attack the droids in the command center. The clone captain shot several droids with one of his blaster pistols before he engaged and disabled the vibroblade-wielding droid commando commander with his bare hands.

However, the clones' victory was short-lived. The five clones discovered that a Separatist fleet&mdash;under the command of General Grievous&mdash;was passing over the moon and also learned that the droids had hotwired the station's "all-clear" signal to prevent the Republic from learning of the Confederacy's impending attack. Because of the lack of response from the droid commandos, a C-9979 troopship was dispatched with battle droid reinforcements to ensure that the base did not cease transmitting the beacon. Knowing that his men would not be able to hold off the droids for long, Rex formed a plan to destroy the station and alert the Republic of the imminent invasion. Deducing that the Confederacy's only target of interest in the sector was Kamino, the closest thing that the clones had to a home, Rex rallied and inspired the rookie troopers' efforts to defeat the droids.

While Cody, Hevy, and Fives went to gain time by confronting the advance battle droid forces at the entrance, Rex and Echo ushered several PLNK-series power droids containing highly-explosive liquid tibanna gas into the command center. As the three droids were wired together, Rex encountered problems with the detonator's remote handset. Hevy stayed to repair the detonator, and the other four troopers escaped the station through a grate. However, Hevy was unable to link the handset to the detonator. When the rookie trooper reported back, Rex learned that he intended to detonate the explosives manually. Rex, Cody, Echo, and Fives rushed back to aid Hevy, but the trooper sacrificed himself, destroying the base and warning the Republic of the invasion. The Republic fleet arrived and forced Grievous's ships out of the system, and the four surviving troopers were taken to the fleet in LAAT/i gunships. Aboard the Resolute, the no-longer-"shinie" Echo and Fives were commended by Generals Skywalker and Kenobi for their service, and Hevy's sacrifice was honored. Impressed by their efforts, Rex inducted the two troopers into the 501st Legion.

Further campaigns
"Let's try not to blow up the ship before they get off this time."

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

Rex sent trooper Denal on several missions to the planets of Rodia, Tatooine, and Orto Plutonia regarding a Confederate superweapon that was capable of concealing entire armies from the Republic. Denal was able to destroy the superweapon at its construction base before being sent on another mission by Rex. Eventually, Rex was dispatched with Senator Padmé Amidala, her protocol droid, C-3PO, and astromech droid R2-D2 to Christophsis to investigate information given to the Republic by Ros Lai&mdash;a Nightsister that had betrayed the fellow members of her sect&mdash;regarding the Nightsisters' alliance with Count Dooku and the Confederacy. However, once Amidala had confirmed that the Separatists were mining on the planet, her ship was shot down over Christophsis. Rex was injured in the crash, and he was imprisoned with the others in the Separatist base. While there, the four overheard the guards saying that the Confederacy was harvesting crystals from the planet core, which were to be used to power the Devastation, a newly-constructed Separatist superweapon.
 * FIT IN KEEP THE FAITH SOMEWHERE

A Jedi team of two was sent to Christophsis in an LAAT/i gunship with Clone Commander CC-1004, nicknamed "Gree," to rescue the senator. The two Jedi freed the captives, and while R2-D2 and C-3PO went to assist the Jedi in their continuing investigation, Senator Amidala helped Rex to the gunship. The two rendezvoused with Gree's transport, and the clone captain was treated with a medical console. Rex participated in a battle on a planet against anti-Republic forces with Skywalker and Tano, during which both sides made use of heavy artillery. When Skywalker and Kenobi infiltrated Count Dooku's Munificent-class frigate over Vanqor in an attempt to capture the Sith Lord, Rex took Admiral Yularen's place of commanding the Resolute&mdash;as the admiral was recovering from a run-in with the Confederate warship Malevolence &mdash;and served aboard the Star Destroyer with Tano.

Once the two Jedi were aboard the frigate, the Resolute opened fire on the Separatist vessel, causing damage to the ship. Dooku managed to escape in his solar sailer, and Skywalker and Kenobi gave pursuit in a stolen Sheathipede-class shuttle, telling Rex and Tano to follow in what ships they could round up. Both Dooku and the Jedi crash-landed on Vanqor, and Tano took a Nu-class shuttle to retrieve Skywalker and Kenobi. While the Jedi were unable to capture Dooku, a band of pirates took the Sith Lord to Florrum and imprisoned him. Rex was present when Skywalker and Kenobi received the assignment by the Jedi Council to verify that Dooku was in the pirates' captivity so that the Republic could pay the Sith Lord's ransom of one million credits. However, the two Jedi were also taken hostage by the pirates, and while they broke free, Dooku escaped separately.

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

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 Venator-class Star Destroyers had been decimated by several Munificent-class frigates, with only Secura's command ship, the Liberty, maintaining altitude. As rocket droids were launched from the Separatist frigates to infiltrate and eliminate 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 evacuate the troops aboard the Liberty.

The gunships opened fire at the droids, and Skywalker went ahead of the others to the cruiser. A rocket droid attacked the gunship carrying Rex and Tano, and the craft's clone pilot was forced out of the cockpit. The clone captain and Padawan caught the pilot and pulled him into the gunship's troop bay. With its controls sabotaged by the droid, the gunship plummeted toward Secura's Star Destroyer. As soon as their vessel crashed into the cruiser's hull, Tano, Rex, and their squad escaped from their burning gunship and ran through the ship's corridors, destroying all droids in their path. The Padawan and clone captain caught up with Skywalker, Secura, and Clone Commander CC-5052, nicknamed "Bly," in the cruiser's hallways and joined them on their attack run to eliminate the battle droids. The group headed to escape the crippled Liberty from a Consular-class cruiser docking in the lower hangar that Skywalker had called in as an escape craft.

As the gangway to the frigate was extended, however, the Confederate fleet's increasing fire caused an inferno to rage through the Republic Star Destroyer. Sacrificing himself, Skywalker Force-pushed the others into the airlock, sealing the blast doors shut. The Jedi General used the Force to hold back the flames, but the explosions finally blasted through the doors, and he was thrown against the airlock from the explosion. Tano and Secura managed to save Skywalker, bringing him onto the frigate. The Republic ship detached from the Liberty and headed for the Resolute. As the frigate began to dock to Skywalker's flagship, a Vulture droid attack erroneously activated the frigate's hyperdrive. The Resolute was able to maneuver away in time, and the Republic frigate jumped to hyperspace with the Jedi, clone officers, and other trooper evacuees aboard. While Skywalker was treated in the frigate's medbay, Bly discovered that the vessel's navigational computer had incorrectly inputted the coordinates, heading the craft straight for a star. Rex joined the others on the bridge, and the group decided to shut down all primary power units to disengage the ship's hyperdrive.

With Tano piloting the frigate, the ship's power was deactivated. Because of the vessel's uncontrollable speed and the lack of artificial gravity, Rex lost his grip on the back of the Padawan's seat. The clone captain was smashed against Secura, causing the Jedi to lose her hold on the power switch. Secura telekinetically reactivated the switch, and with artificial gravity back in operation, she and Rex landed on the floor. Tano maneuvered the craft to avoid the star but was unable to stop the ship from heading straight toward the nearby planet of Maridun. Entering the planet's atmosphere, the frigate lost several of its parts before crash-landing on the planet. Everyone aboard the ship escaped the burning wreckage, and Rex helped another trooper out of the craft. After a makeshift shelter had been erected for Skywalker, Secura, Tano, and Bly took the squad of clones to find help for the injured Jedi while the clone captain stayed to keep watch over Skywalker. Before the Padawan left with the others, Rex assured her that he would take good care of her wounded Master and wished her luck.

Under the cover of night, the clone captain diligently guarded Skywalker. As the Jedi awoke, a mastiff phalone &mdash;a carnivorous species native to Maridun &mdash;that had been watching the clone captain and Jedi for hours pinned Rex down and trapped the clone's blaster hand under one of its claws. Rex managed to fire a shot, startling the creature and scaring it away as he aimed several laser shots at its retreating form. The clone captain remained on the alert throughout the rest of the night. After daybreak, Skywalker regained consciousness once more. Although Rex insisted that the Jedi maintain his rest, Skywalker told the clone captain that he could hear the sound of returning mastiff phalones. Both Rex and Skywalker 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 shelter and ripped it apart, knocking Skywalker and Rex aside.

At that moment, Tano and Bly returned with Wag Too, a healer from the planet's pacifist Lurmen colony. Too wrapped a rope around the feet of the remaining mastiff phalone, and Tano assisted the Lurmen in attempting to pull the creature off its balance. Despite an injured arm, Rex used his other hand to help the two, and the mastiff phalone was pulled to the ground. Too tied the rope around the creature's legs, securing it. With the threat removed, 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. Later, while keeping watch on the outskirts of the village, Rex noticed an incoming Confederate C-9979 landing craft and reported this development to Bly back at the colony. The clone commander told Rex to return to the village, and the captain joined the others in the seedpod hut where Skywalker was being treated. To ensure that the Lurmen were not slaughtered for their presence, the Jedi and clones decided to hide from the Confederacy.

Rex and Bly assisted Skywalker to a nearby field of tall grasses behind the village. While there, the clone captain expressed his lack of understanding for the Lurmen's pacifistic views. Though Tano believed that they simply had no courage, Secura intervened and stated that it took courage to follow one's beliefs. Skywalker suggested that they steal a shuttle from the Confederacy to escape the planet, and Rex agreed with his general, eager with the chance to steal from the Separatists. Tano suddenly noticed that a Separatist recon droid was spying on them, and the Padawan and the two clones gave pursuit of the fleeing droid. Secura worked her way in front of the droid and cut it in half with her lightsaber when it flew straight at her. From a nearby tree, the Jedi and clones caught sight of the well-guarded Separatist base and watched as General Lok Durd deployed a squad of battle droids outside of the base with two Armored Assault Tanks and a tank-mounted defoliator cannon.

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 test subjects for the experimental weapon. A defoliator capsule was fired and exploded, beginning to decimate all life forms in the area. Rex and Bly fled and fired their blasters' grappling hooks at the tree to escape the expanding wall of fire and avoid being killed. Although the clone captain made it to safety, the clone commander tripped on a log and misfired, but Secura was able to swing down on a vine and rescue him. The energy wave began to slow its expansion, and the two droid testees appeared, unscathed. The Jedi and clones watched as Durd departed with an armament of troops, and Skywalker deduced that the Confederate general intended to test the defoliator on the Lurmen village. Resolving to save the Lurmen, Skywalker, Tano, Secura, Rex, and Bly waited until night had fallen to ambush the droids guarding the Separatist base. After Skywalker and the clones had cut down the droids 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 droids' communication center and eliminated the droids controlling the facility. Noticing two deflector shield generators, Rex and Bly brought the devices onto their stolen Sheathipede-class transport shuttle and accompanied the Jedi back to the Lurmen colony. Day broke again, and the Jedi and clones arrived at the Lurmen village in the shuttle. Keeping watch from the perimeter of the village, Rex noticed the inbound droids only minutes away from the colony. Despite the protests of the Lurmen chieftain, Tee Watt Kaa, the Jedi and clones moved several seedpods to form a barrier in front of the village and also moved the shield generators in place. The clone captain noted that the droids were holding position to attack the village with their-long range artillery. As a defoliator shell was fired, the deflector shield generators were activated, and the defoliator's energy wave was blocked by the shield.

Unable to attack the village from afar with the shield intact, Durd dispatched his first squad toward the village, and the Jedi and clones emerged from the shield. While Skywalker, Tano, and Secura charged at the droids, Rex and Bly provided covering fire with their DC-15A blaster rifles. Although they were 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. With an advantage in numbers, some of the droids slipped past the Jedi, forcing the two clones back behind the pod barrier. The battle 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 village, and Skywalker managed to disable the defoliator and capture Durd. With aid from Too and several other Lurmen who sacrificed their pacifist upbringings to help defend their colony, the Republic squad was able to save the village. 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.

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

Rex later was dispatched with Skywalker, Kenobi, and a group of cold assault troops to investigate a loss of communication with Glid Station, a Republic base on the ice world of Orto Plutonia. The clone captain 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. Upon arriving at the station in several LAAT/i gunships with the Jedi along with Chairman Chi Cho and Senator Riyo Chuchi, representatives of the orbiting moon of Pantora, Rex and his men placed sensor beacons to survey the area. The clone captain then accompanied Kenobi into the base and discovered that the station's troopers had been slaughtered without any evidence of a battle with Separatist battle droids. Following their scouts' discovery of a nearby Confederate base, Skywalker, Kenobi, Rex, and a group of clones proceeded to the facility aboard Freeco bikes. Arriving at the base, which was composed of two combined Trade Federation XT Beetle Transports, Rex assisted Skywalker in placing sensors around the building before entering the base with his Jedi General. Meeting Kenobi inside the base's control center, Rex and the two Jedi uncovered a holorecording from a communications hub of a large creature attacking a B1 battle droid.

Rex reported that the droids' log indicated that they had been investigating the southern canyon. While the Jedi departed to follow the lead on the droids' last known location, the clone captain and the other troopers returned to Glid Station. As a storm began to brew outside, Skywalker and Kenobi returned to the Republic base and reported their findings&mdash;contrary to the findings of previous scouting parties, Orto Plutonia was inhabited by a species called the Talz. When Chairman Cho learned of the Talz, he immediately ordered Rex to prepare his troops for battle, but the Jedi intervened and stated that a meeting had been arranged with the Talz to negotiate peace. As the Republic forces prepared to depart, Rex reported to Skywalker that the gunships would not be able to take off in the storm, and the Jedi ordered the rest of the clone platoon to remain at Glid Station&mdash;despite Chairman Cho's beliefs, they were not going to war. The clone captain set off with the Pantorans, Jedi, and a squad of troopers in Freeco bikes for the Confederate base, which had been arranged as the neutral meeting ground.

Upon arrival, Cho told Rex to position his troopers on a nearby ice ridge from which to ambush the Talz, but Kenobi countermanded the order&mdash;the Talz had already arrived. Leaving Rex and the clones outside with orders to avoid provoking the Talz, the Jedi and Pantorans entered into negotiations with the warrior species' chieftain, Thi-Sen. Despite the Jedi's efforts for the contrary, 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 the chairman. Approaching several Narglatch-mounted Talz, Cho immediately ordered the clones to open fire. Although Rex reminded the chairman that the clones were only there for his protection, the captain and his troops were forced into battle when more Talz appeared and ambushed them.

A Talz warrior and a Narglatch attacked Rex's Freeco swoop. Forced out of his vehicle, Rex shot the warrior and its mount. Kicking his bike over for cover, the clone captain told his men to do the same to form a defense from the Talz. As spears continued to fly at the Republic group, Rex ordered his men to retreat. Though Cho refused to pull back, the chairman was soon incapacitated in the back with a spear. The clone captain slammed a BARC speeder into a Talz that attempted to kill Cho and defended the wounded chairman from more of the warriors. Carrying Cho onto a spare speeder, Rex joined the rest of his men's retreat. However, their escape was blocked by a collapsing ice bridge. Backed against a gorge, the clone captain signaled his remaining men to use their vehicles as cover. As the clones countered the Talz's spears with blaster fire, they were saved by five LAAT/i gunships with the Jedi, Senator Chuchi, and troop reinforcements aboard. With heavy casualties, the battle had been bloody for both sides of the conflict. After Cho succumbed to his injuries and passed on, Chuchi was able to establish peace with the Talz, leaving Orto Plutonia in the hands of the Talz colony. The battle over, Rex departed with the Jedi and senator in one of 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

After the Separatist-allied Doctor Nuvo Vindi was discovered to be using a laboratory on the planet Naboo to recreate and modify the long-eradicated Blue Shadow Virus, Rex was dispatched with Skywalker, Kenobi, Tano, and several clone units to cripple Vindi's facility. Tano detonated several thermal detonators to breach the lab, and Rex and a squad of troops joined the Padawan in drawing the attention of the laboratory's droid defenses so that Skywalker and Kenobi could infiltrate the lab separately without retaliation. In one of the lab's tunnels, Rex and his men followed Tano against a squad of B1 and B2 battle droids. The Republic battle group's charge was cut short with the appearance of two droidekas, and the Padawan and the clones were forced to retreat.

As several of their men fell to droid fire, Tano, Rex, and the clones were saved with the appearance of Master Kenobi and the clone bomb squad, who entered the tunnel and collapsed part of the roof on the droids. Kenobi and his squad headed to find Vindi's virus bombs&mdash;which the doctor had manufactured to spread the Blue Shadow Virus&mdash;while Tano, Rex, and their squad occupied the remaining droids. However, the situation became much more dire when Dr. Vindi remotely activated the bombs. While Skywalker and Kenobi pursued the fleeing Vindi, Tano and Rex went to search for a missing bomb in possession of the doctor's servant droid, LEP-86C8. Senator Padmé Amidala and Representative Jar Jar Binks, who had been captured by Vindi before being freed by Skywalker, found the droid and recovered the bomb, and Tano and Rex quickly took the bomb squad to the arboretum where Amidala and Binks were located.

Having found the last virus bomb, the bomb squad was able to disable all of the explosives and prevent the release of the virus. The Jedi were also able to capture Vindi and prepared to escort the Separatist doctor to Naboo's capital of Theed for trial. Unbeknownst to the Republic forces, Vindi's servant droid had removed the virus vial from the last bomb before escaping. Using a spare bomb in the bomb room, LEP-86C8 managed to release the Blue Shadow Virus. Elsewhere in the lab, Tano, Rex, and several troopers rushed to the facility's safe room with the plague in pursuit through the air. The Padawan held the safe room's closing blast doors open with the Force, allowing Rex and the clones to jump in. With the clone captain and his men now holding the crack open, Tano managed to clear the jump. However, the squad soon discovered that the doors had not been closed fast enough, allowing some of the virus to enter the room. Despite being infected with the strain, Rex believed that he and his men could still continue fighting.

Wearing enviro-suits for protection from the virus, Senator Amidala and Representative Binks opened the door to the safe room, dismayed that they could not do anything to help the contaminated Padawan and clones. In order to stop the remaining battle droids from breaching the compound and releasing the virus to the rest of Naboo, the Republic group 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. Regrouping, the clone captain and the senator brought down the last battle droid that was attempting to cut through the south exit hatch. Confronting two droidekas, Rex and the rest of the squad provided covering fire for Tano as she charged and destroyed the pair of droids. However, Senator Amidala's suit was compromised in the attack, infecting her with the virus as well.

As the last of the droids were defeated, Rex helped Senator Amidala treat the other four infected clones, even though the clone captain was suffering from the virus as well. When the senator lamented on the dying clones' wasted lives, the clone captain replied that it was what the troopers were born to do. However, Tano fainted, overcome by the virus, and Rex caught the Padawan as she collapsed. Meanwhile, Skywalker and Kenobi were able to collect enough Reeksa root&mdash;a cure for the Blue Shadow Virus &mdash;to neutralize the plague on the planet Iego. The Jedi returned to Naboo to administer the antidote, and the virus was neutralized. Slated to make a full recover, Rex and the others infected by the plague were ushered away in stretchers by several 2-1B medical droids onto awaiting LAAT/i gunships. Before departing, the ailing Rex made clear that he would not be training Binks, who had been recommended by Amidala and Kenobi for marksmanship training.

Battle 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, Rex was deployed with Skywalker, Tano, Admiral Yularen, and a Republic fleet of three Star Destroyers to eliminate the Confederate blockade surrounding the planet. However, the arrival of Separatist reinforcements caused the Republic's offensive to backfire. The cruisers Resolute and Defender were damaged and forced to retreat, while the Redeemer fell apart under heavy 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. The clone captain informed Skywalker of the incoming transmission, and the Jedi told Rex to put together a damage report. Rex was present when Skywalker informed Windu and Kenobi of his battle group's losses. Despite only half his original forces remaining, Skywalker was given one planetary rotation to eliminate the blockade.

Skywalker sent Rex to locate Tano, and the clone captain found the Padawan in the Star Destroyer's medbay with an unconscious Yularen&mdash;who had been wounded in the first stages of the battle&mdash;and informed her that her Master was looking for her. When Skywalker later ordered the Defender evacuated, Rex assisted the Jedi General in supervising the transfer of the Defender supplies to the Resolute. Tano arrived in the Resolute hangar bay, and Rex oversaw operations while Skywalker explained the plan to his Padawan&mdash;Skywalker would pilot the Defender alone and take out the blockade's lead ship, leaving Tano in charge of the Resolute. After the Jedi General departed, Rex and the Star Destroyer's naval officer were present when Tano arrived on the bridge of the Resolute.

Upon learning of Skywalker's plan, the clone captain and officer were hesitant with the strategy&mdash;Rex believed that the odds "were very much against them." To protect the Resolute from the firepower of the six remaining Confederate frigates, Tano presented a plan to angle the hull of the Star Destroyer toward the blockade, allowing starfighters to be launched and drawing the Confederate frigates in with a classic Marg Sabl maneuver. Both Rex and the naval officer were concerned about the plan's chances of success, but a revived Yularen supported Tano. Upon the Resolute return to the Ryloth system, Tano led the Star Destroyer's starfighters in the assault on the enemy ships. 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, the Padawan told the clone captain to dispatch a shuttle to retrieve Skywalker's escape pod.

With the blockade destroyed, the Republic ground forces were able to land and eventually liberate Ryloth. Following the recapture of Ryloth's capital, 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. The clone captain led an assault on the droid forces in the wastes close to the city of Resdin, where the Separatist holdouts were based out of. Rex charged the battle droid lines, defeating several droids single-handedly. Skywalker and Tano then arrived, taking out more droids themselves. The two Jedi left the clone captain with the rest of the detachment and infiltrated the Separatist lines. Rex rejoined the pair after they had defeated a tri-droid, reporting that the Republic scouts had confirmed the large droid to have been the last of their enemies in the sector. Skywalker ordered the clone captain to prepare his men to move into Resdin, where large pockets of resistance were still located. Rex joined Skywalker, Tano, Clone Sergeant CS-1004, nicknamed "Kano," and trooper Rookie on a gunship that took them into the ruined city.

Once the troops had disembarked, the clone captain 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. The two Jedi decided to reactivate the bridges and left with a warning from the clone captain, who reported 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, Sergeant Kano and his platoon of troopers 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, Captain Rex and Advanced Recon Force Sergeant CS-2207, nicknamed "Boomer," went on a night patrol of Resdin using All Terrain Recon Transports. Fighting battle droids, the two made their way through the city's streets. After exiting a narrow alley and arriving at the large area below, Rex and Boomer were ambushed by groups of B1, B2, and DSD1 droids. Employing their AT-RT walkers' guns to defeat the droids, the two troopers went across a cliffside path and eventually reached 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 run out from behind a building, the pair dismounted their walkers. Reporting back to the Jedi and transmitting their coordinates, Rex and Boomer came under attack, and the holoconnection was severed. Waking up inside an underground hangar in binders, the two clones 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. The clone captain attempted to get up but was knocked back down by Bane, and the bounty hunter pointed a blaster pistol at the trooper. As Separatist battle droids broke into the room, Bane showed a detonator to Rex and Boomer, and the former deduced that it was for explosive charges in their binders. Ordering the pair on their feet, the bounty hunter ordered the clones to protect him and his crate or else risk being "blown to pieces."

Bane unlinked the troopers' binders, allowing them to move freely and make use of their weapons. Complying with the bounty hunter's demands, Rex and Boomer used several crates for cover and fought the B1 and B2 battle droids advancing through the main hangar door. After the clone captain accessed the door's controls from a computer beneath the platform that Bane was standing on, the droids continued to enter the hangar through several auxiliary tunnels. Rex closed the two hatches from nearby terminals, halting the droids' advance. A Vulture droid broke through the main entrance and attacked the troopers, but the clone captain used artillery provided by Bane to make short work of the large droid fighter. Rex and Boomer joined Bane on the upper platform, and although the ARF sergeant believed that they could defeat the bounty hunter, the clone captain kept him focused on the situation at hand&mdash;Separatist reinforcements had arrived in the form of B1, B2, and sabotage droids.

Skywalker and Tano eventually found Rex, Boomer, and Bane in the hangar battling waves of droids. Grudgingly deciding to assist the bounty hunter, the two Jedi joined the fight. After Skywalker destroyed a large tri-droid and ended the Confederacy's advance, Bane opened fire on the Jedi and clones. Skywalker deflected the bounty hunter's blaster fire, causing Bane to lose his balance and fall from his perch atop a platform. Learning of the bounty hunter's "arrangement" with the troopers, Skywalker severed the clones' binders, neutralizing Bane's bargaining chips. Rex and Boomer disarmed the bounty hunter. 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 dispatched Rex and Boomer to find an elevated position from which to provide covering fire, planning to follow with Tano, Bane, and the bounty hunter's crate, which the Jedi intended to take back to the Republic for investigation.

The two clones left the hangar and took a path overlooking Ryloth's wastes. Battling Separatist droids and fighting their way through starship wreckage, Rex and Boomer eventually destroyed a tri-droid roaming the wastes. The troopers were assaulted by waves of battle droids coming down from an adjacent hill. Defeating the droids there, Rex and Boomer encountered a pair of tri-droids emerging from within a tunnel. Using rocket launchers, the clones managed to defeat the massive droids one after another and signaled to Skywalker that they were in position. The Jedi and Bane left the hangar, and Rex reported to Skywalker that droids were converging on the three from all directions. With the group in sight, the clone captain commented on the less-than-pleasing visual appearance of Bane, who had been forced to carry his own crate back to his ship. While Rex and Boomer engaged the droids above a canyon, the Jedi and bounty hunter fought waves of droids below. The two troopers followed Skywalker, Tano, and Bane through the canyon, destroying droids as they went. 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 the Jedi and Bane continued along a cliffside path, the clone captain 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 before the two troopers departed to rendezvous with the Jedi at The Sleight of Hand. Rex and Boomer arrived at the site of the ship to find Skywalker and Tano in the process of battling the Separatist scientist Kul Teska, whom Bane had stolen the crate from. Teska encased the two Jedi inside an energy bubble, and Skywalker told the troopers to fight the Skakoan instead of rescuing them. Fighting the two clones, Teska was eventually forced to issue an ultimatum: save their Jedi commanders or kill him. The energy bubble began to close in on Skywalker and Tano, and Rex and Boomer decided to rescue the Jedi. While the clones deactivated the sphere, Teska boarded The Sleight of Hand with his retrieved crate. The Jedi and clones converged on the ship but were unable to prevent the Skakoan scientist from escaping. Although Rex believed that he had failed Skywalker, the Jedi General gave the clone captain his thanks. Tano also discovered that Bane had fled.

Immediately following the discovery of Teska's underground base on the planet Behpour&mdash;from which the Skakoan intended to collapse the Naboo sun&mdash;Rex and Commander Cody accompanied Skywalker, Tano, Kenobi, and Windu to destroy the facility. The two clone officers led a diversionary assault on the Separatists elsewhere on the planet with the intent of distracting the droids so that Skywalker and Kenobi could disable the base's shields. Marching through a canyon on AT-RT walkers, Rex and Cody battled their way through B1 and B2 battle droids. Crossing a river of acid generated by the planet's core, the two troopers continued on through the canyon, eliminating all of the droids they encountered along the way. Rex and Cody blasted several circular platforms to make their way up a ridge before destroying all of the fuel cells and droid tanks in the area. With the droids distracted, Skywalker and Kenobi were able to infiltrate the base and disable its shields. Windu and Tano led the main clone detachment to enter the underground facility and secured the entrance.

Inside the base, Rex and Cody met with Clone Commander CC-6454, nicknamed "Ponds," who had been sent by Windu to help set up an evacuation zone. The group of clones fought their way through the facility's droids and moved across the expanse of walkways. Arriving at a landing pad, the troopers were confronted by a Vulture droid, which Rex blasted and defeated with his rockets. From a computer terminal, Cody used the base's emergency beacon to signal R2-D2, and the astromech droid piloted the Twilight to the platform to serve as an escape vessel. However, Count Dooku himself soon arrived to confront the clone troopers. Rex, Cody, and Ponds immediately took aim and fired their blasters at the Sith Lord, but Dooku Force-pushed the clones into the Twilight cargo bay and closed its hatch shut. The Confederate Head of State used the Force to topple a large beam onto the Republic freighter, plunging the clones and their ship into the depths of the base.

The clones survived the fall, returning to rescue Kenobi and Windu&mdash;who had arrived and were dueling Dooku&mdash;with the Twilight when the landing platform began to collapse. Rex greeted the Jedi Masters outside of the cargo bay, where he learned that Skywalker still had not shown up. The Twilight was soon rocked by falling debris, and unable to wait for the other Jedi, the freighter escaped out of the base. Skywalker and Tano were able to defeat Teska, rescue Senator Padmé Amidala&mdash;who had been held captive by the Skakoan scientist&mdash;and disable the gravity weapon. Using STAPs, Skywalker, Tano, and Amidala escaped the base to the Twilight, and the freighter fled Behpour with the Jedi and clones aboard shortly before the facility was destroyed from the malfunctioning weapon.

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 assault at Devaron

Rex was dispatched to defend the planet Felucia alongside Skywalker, Tano, Kenobi, and Commander Cody from the Separatist Droid Army. After the Republic troops arrived and engaged the Confederacy, however, they began to be overwhelmed. Once LAAT/i gunship reinforcements had broken through the Separatist blockade around the planet and landed in the clearing where the main force was based, Rex and Cody immediately led their troops onto the escape craft, backing into the vessels while returning blaster fire at the approaching waves of battle droids. Skywalker and Kenobi boarded the gunships, which promptly lifted off to retrieve Tano, who had led a squad on a patrol of the dense jungle. Though the Padawan initially refused to retreat, the gunships landed between her forces and the droid army, forcing her to abandon the fight. The clone troopers aboard the craft fired at the advancing battle droid lines but were unable to halt the droids. The Republic detachment escaped shortly before the ground vehicles that Tano had left behind were blown to pieces.

Following Cad Bane's theft of a holocron from the Jedi Temple Archives, Rex accompanied Skywalker, Tano, and Admiral Yularen aboard the Resolute to retrieve the holocron from the bounty hunter. Bane, however, had captured Jedi Master Bolla Ropal&mdash;the keeper of the Kyber memory crystal, the contents of which could only be read with a Jedi holocron&mdash;at Devaron, where the Jedi Master commanded a Republic base. The Resolute arrived in the Devaron system and attacked Bane's fleet of Munificent-class frigates, gradually decimating the bounty hunter's escort. As Bane's command ship fled, the Republic Star Destroyer targeted the ship's hyperdrive, preventing the bounty hunter from escaping to hyperspace. Assembling their forces in the Resolute hangar, Rex rounded up three brigades of troops for the impending mission.

When the clone captain learned from Skywalker that they were to be boarding an enemy frigate, he expressed hesitancy, as there were only a few starfighters and the Twilight available as assault craft. After Admiral Yularen arrived, Skywalker revealed his intent to transport his forces to the frigate by way of several AT-TE walkers. Though Yularen was appalled, Tano noted that the walkers were pressurized, and Rex added that they were equipped with magnetic feet for extra grip, complementing Skywalker on the resourceful plan. Despite Yularen's protests, Skywalker ordered his forces to prepare to board the frigate. Rex ordered Execute Battalion to take walker ATAT300, while Carnivore Battalion was to make use of Walker 773. Once the troops were ready, the Resolute moved into position and dropped ATAT300, 773, and another walker with the clones and Jedi aboard onto Bane's crippled frigate. The AT-TEs exchanged blaster fire with several STAPs and Vulture droid starfighters that were deployed from the vessel. Rex and the clones provided covering fire and enabled the two Jedi to cut down the Vulture droids.

Once the initial droid forces had been repelled, R2-D2 opened a hatch on the ship's roof, allowing the Jedi and clones to enter the vessel. Arriving at the frigate's bridge, Skywalker, Tano, and Rex stormed into the room and led a charge on the droids manning the ship's controls. With the frigate's droid crew dispatched, R2-D2 uncovered a record of a holotransmission between Bane and Trade Federation Viceroy Nute Gunray. The Jedi learned that the bounty hunter now had both the holocron and the memory crystal in his possession, having stolen the latter from Ropal. As Skywalker sent the clone captain 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 joined the two Jedi to search for the captive Ropal. When Tano found the dead Jedi Master in one of the ship's holding cells, Skywalker ordered the clone captain to have some men take Master Ropal back to the Resolute. With the frigate's deck lights suddenly deactivating, R2-D2 used his headlamps to lead the Jedi and clones through the ship's dark hallways in search of Bane.

Upon blindly hitting his helmet against a 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, Skywalker, Tano, Rex, and the clones immediately gave pursuit of the bounty hunter. The squad followed Bane into the vessel's darkened gunnery deck, where the bounty hunter revealed his amassed battle droid forces by switching on the lights. Bane and his droids opened fire on the Jedi and clone troopers, who immediately returned the droids' blaster fire. The bounty hunter soon decided to make the fight "a bit more interesting" by switching off the artificial gravity. Rising off the ground, Rex and the other troopers used their magnetic gripsoles to latch onto various footholds and continue firing at the similarly-magnetized droids. The clone captain secured himself onto one of the artillery guns with his magnetic boots before blasting several battle droids in half.

When a blaster cannon–wielding clone hit the disabled carcass of a droid and accidentally released an ammunition canister from a gun, Rex warned his men to check their aim, as the fight would reach a very quick end if one of the shells was detonated. After R2-D2 reactivated the gravity generators, the clones and Jedi dropped to the floor. Bane lured Tano into a trap, and the Padawan followed the fleeing bounty hunter into a dead-end hallway that he promptly sealed. While Skywalker attempted to cut through the blast doors to rescue his trapped Padawan, Rex's warning was proven ineffective when a battle droid tripped on the head of one of its fallen comrades and misfired at an ammunition canister. The blast from the exploding shell caused falling debris to cut off the clone captain and the rest of the troopers from Skywalker. Unable to cut through the rubble, Rex called out to his Jedi General and finally got through to him, confirming that he was alive. Skywalker told the clone captain to return to the frigate's hangar, secure a transport to escape the doomed frigate, and wait for himself and Tano as long as possible.

Arriving in the hangar bay to find the rest of the clone forces battling B1 and DSD1 dwarf spider droids, Rex ordered his men to commandeer a nearby Sheathipede-class shuttle. While engaging the battle droids in a crossfire and using several crates as cover, Rex received word from Admiral Yularen that the frigate's main reactor was exposed and would implode at any moment. The clone captain sent troopers Denal and Koho to find and assist Skywalker, stating that the frigate would not last much longer. After the clones had secured the shuttle, Rex and his troops continued to return fire at the attacking droids. As the clone captain began to herd his men onto the craft, he finally received word from Skywalker, who had rescued Tano and was heading to the hangar with her. The clone captain informed the Jedi that with the reactor about to explode at any moment, the clones would not be able to wait much longer for them. Skywalker and Tano eventually arrived, and as the shuttle lifted off the ground, Rex waved the two Jedi onto the shuttle with the rest of the clone troopers.

Before leaving the doomed frigate, the shuttle maneuvered around to pick up trooper Denal, whom the rest of the squad had witnessed shoot Bane on an overhang above the hangar. However, the clone armor–clad figure was in fact Bane himself, as the bounty hunter had instead killed Denal and stolen his armor. Learning of "Denal's" inability to retrieve the holocron, Skywalker ordered Rex to get the squad out of the frigate. The Jedi and clones escaped on the shuttle shortly before the vessel broke apart. Returning to the Resolute, Rex and another trooper discovered that someone had left behind green blood on the deck of the shuttle. The clone captain showed his discovery to Skywalker, stating that it definitely was not from any of the clones. Meanwhile, Tano realized Bane's ruse, and the bounty hunter fled toward the nearby starfighters after incapacitating Tano. Although Skywalker and Rex pursued Bane, they were unable to stop him from stealing a V-19 Torrent starfighter and escaping to hyperspace.

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

Following the discovery of a series of Separatist droid foundries newly built by Archduke Poggle the Lesser on Geonosis, Rex was sent to lead a 501st Legion contingent to reconnoiter the site of the outbreak of the Clone Wars. 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 confirmed from preliminary scans that droid foundries in various stages of construction were at work in the world's northern and southern hemispheres. In his report back to the Jedi High Council, the clone captain stated that the Geonosians were mounting far from a simple revolt and recommended a full-scale planetary invasion to retake Geonosis. Rex promised to provide a further breakdown of the planet's defenses before ending his transmission. Based on the clone captain's recommendations, the Jedi Council sent a massive invasion force under the command of Generals Ki-Adi-Mundi, Luminara Unduli, Kenobi, and Skywalker, Commander Tano, and Admiral Yularen to recapture the planet and shut down the droid factories there.

After arriving in orbit of Geonosis, Rex, Cody, and Clone Commander Jet joined Mundi, Kenobi, Skywalker, Tano, and Unduli&mdash;participating in the meeting via a holotransmission&mdash;in the war room of one of the Star Destroyers of the invasion fleet to establish the plan of attack. The Republic forces intended to execute a three-pronged assault on the Geonosian defenses and rendezvous at a point a short distance away from the ray shield protecting the droid foundries in order to fortify a staging area and take out the 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 briefing finished, the Jedi and their clone officers split up to begin preparations for the invasion. Skywalker's force of LAAT/i gunships and LAAT carriers hauling AT-TE walkers to the surface was the second to launch from the fleet, following Kenobi's deployment and preceding Mundi's troops.

The Republic forces entered the atmosphere of the planet to encounter heavy resistance from Geonosian Nantex-class starfighters and the Separatist artillery below. The gunship carrying Skywalker, Tano, and Rex was among the first to be shot down, crash-landing and skidding across the surface. Skywalker heaved the wreckage of the gunship away, freeing himself and his troops from the fallen craft. The Republic detachment's landing was greeted by nearby Geonosians manning blaster cannons. While Rex and the clones used the disabled gunship and various outcrops as cover to return the Geonosians' blaster fire, Skywalker charged the warrior insurgents. Tano, Rex, and the troopers soon joined the Jedi General in attacking the Geonosians at a closer proximity. During the ensuing firefight, Skywalker's AT-TE walkers were destroyed. The clone captain reported his squad's situation to Commander Jet and attempted to hail General Kenobi for reinforcements. Rex learned from Cody that Kenobi had not reached the landing site and of the clone commander belief that the Jedi Master's gunship had been shot down.

The clone captain informed Skywalker and Tano of Kenobi's inability to provide support. With his forces left on their own without reinforcements, Skywalker ordered the clone captain to mobilize their men in preparation to charge the gunners while he and his Padawan provided cover for them. Rex assembled the troops and led them to rush the blaster cannons alongside the Jedi, cutting through the Geonosians' artillery. Continuing toward the rendezvous point, the group's trek led them to a canyon blocked by a massive Separatist barricade riddled with gun emplacements and B1 and B2 battle droids. Skywalker, Tano, Rex, and their men were forced to take cover from the incoming waves of fire. Faced with the task of taking down the wall to clear the way to the rendezvous, the two Jedi each took a backpack filled with thermal detonators and left Rex in charge of the troops to provide cover as the pair climbed the wall. After Skywalker and Tano had arrived on the barrier and were in the process of fighting their way through its droid defenses, Rex released a barrage of lasers at one of the barricade's gun emplacements, eliminating it single-handedly. The clone captain ordered his men to focus on the battle droids at the top of the wall before heading to ascend the barrier himself.

Rex arrived to assist the two Jedi in their fight against a pair of droidekas, sneaking up behind the droid attacking Tano and walking right through its laser deflector shield. The clone captain blasted the destroyer droid's "head", causing the reeling droid to release unfocused fire at its comrade. With the other droid occupied with the sporadic laser fire, Skywalker was able to cut through the remaining droideka. Skywalker and Tano tossed their primed detonator–full backpacks into a nearby hatch and used the Force to levitate Rex off the wall and into the air. The Jedi jumped off the barricade with the clone captain following close behind just as the explosives detonated. Skywalker and Tano used the Force to slow their descent and landed on the ground, employing the Force to halt Rex's fall inches from the ground and bring him to safety. With the wall destroyed, Skywalker helped the clone captain to his feet, and the troops continued on to the rendezvous site.

Running out of the canyon and across the plains of Geonosis, the Jedi and clone troopers noticed several smoldering Geonosians falling out of a nearby clifftop cave. Skywalker recognized Mundi and contacted him, learning that the Jedi Master and his troopers had taken a detour through the cave. The two Jedi Generals joined forces and proceeded with their troops to assist Cody and Kenobi at the landing site. A Y-wing starfighter squadron bombing forced the Geonosians and their Armored Assault Tanks to halt their assault on the Republic forces at the rendezvous point. Mundi, Skywalker, Tano, Rex, and Jet met with Cody and the injured Kenobi to form a plan for the final stage of the operation: destroying the shield generator 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 artillery stations and the shield generator. 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.

The wounded Generals Kenobi and Mundi were ferried 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 Jedi and clone captain moved their troops to the cliff adjacent to the droid factory, which was isolated on the other side of an immense canyon that was only crossable via a bridge. Jedi Master Luminara Unduli and her Padawan, Barriss Offee, soon arrived with LAAT/i gunships and clone trooper reinforcements, and once the pair had landed, Rex greeted them and directed them to Skywalker and Tano. The four Jedi formulated a plan of attack to take out 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 detonate the factory from the inside. After the two Padawans had departed, Rex accompanied the Jedi Generals and the clone troops across the bridge leading to the foundry. Although the assault was risky from the lack of cover, the Jedi intended to "tempt" the Geonosians into fighting them in open warfare.

Deployed factions of B1 and B2 battle droids opened fire on the Jedi and clones, and Rex joined Skywalker and Unduli in leading the Republic troops' charge on the Separatists. The Republic's advance was cut short when Geonosian fighters emerged from several spires behind the clone force. Nevertheless, the surrounded Jedi and troopers continued to cut through the opposing droids toward the factory. With the appearance of a droideka squad, Rex ordered a rocket launcher–armed trooper forward to assist the Jedi. The clone blasted the destroyer 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 confronted with the deployment of several super tanks, newly manufactured by Poggle the Lesser's foundry. At Skywalker's order, Rex mobilized four AV-7 Antivehicle Cannons in preparation to attack the tanks.

Once the massive Separatist tanks had almost reached the other side of the bridge, the clone captain had the Republic cannons open fire on the vehicles. The ray-shielded tanks, however, were able to withstand the barrages of fire and continued their advance. Skywalker, Unduli, Rex, 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 heavy cannons and advancing AT-TE walkers were destroyed, and the clone troopers sustained heavy casualties. Taking cover from the ongoing fire, Skywalker ordered Rex and the rest of the troops to fall back. Although the clone captain was adamant against retreating, he complied when the Jedi General stated that the plan was to draw the tanks onto the bridge, which the two Jedi would destroy and eliminate the blaster-impervious tanks in the only way they saw possible. Once Rex and his men had begun to retreat and lured the still-firing tanks almost all the way across the bridge, Skywalker and Unduli swung under the pass and planted explosives, heading for the other side of the canyon. With the super tanks and detonators in place, Skywalker activated the charges, collapsing the span and plunging the tanks into the abyss below.

As Skywalker and Unduli waited for their Padawans&mdash;who, in the meantime, had planted their explosives at the reactor's core&mdash;the former contacted Rex via comlink and questioned whether he had spotted Tano or Offee from his side of the canyon. The clone captain replied that he had not seen either of them, but also reported that the evacuation ships had arrived. With the droid foundry about to explode, Rex "suggested" that Skywalker get on one, though the Jedi General refused to leave without his Padawan. Meanwhile, Tano and Offee were intercepted by Geonosian insurgents and a super tank at the reactor, and with their explosives stolen, they were forced to fire the tank at the facility's power generator. Rex and the clone troops on the other side of the gorge watched as the factory was hit by a chain of explosions and took cover from the expanding dust cloud that the collapsing factory caused. Once the dust had settled, Rex went with an LAAT/i gunship to find Skywalker and Unduli. The clone captain reported to the two Jedi Generals that the Republic's LAAT carriers were beginning to move the debris to search for the Padawans buried under the factory's remains.

Eventually, Tano was able to boost her comlink's reception with a power converter inside her tank and signaled her Master to her and Offee's location. Receiving the pulse on his Padawan's comlink channel, Skywalker pointed out the trapped pair's location and proceeded to the area with Unduli and Rex. Although the clone captain offered to move the heavy machinery, Skywalker refused, electing to instead employ the Force with Unduli to lift the debris. Tano and Offee emerged from the remains of the foundry, coughing and grimy but safe, and the clone captain waved several troopers over to help them out of the debris field. Once the two Padawans had been reunited with their Masters, Rex convened with Tano and Offee at a staging area, from where he sent the pair back to the fleet for a much-deserved rest. Promising to return after recuperating, Tano and Offee departed with one of the LAAT/i gunships ferrying the wounded Republic troops away for treatment, leaving the clone captain and Jedi Generals&mdash;among them, Masters Mundi and Kenobi, who had recovered from their earlier injuries in battle&mdash;to complete the cleanup on Geonosis.

Personality and traits
"&hellip;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."

- CC-7567, to Cut Lawquane

Gruff, no-nonsense, and tough as nails, CC-7567 was an aggressive clone trooper and a veteran of many battles during the Clone Wars. Hardened and battle-scared by many engagements with the Confederacy, the captain held a reputation as one of the toughest clones in the galaxy. Rex was a freethinking and fearless soldier, and though he did not hesitate to give higher-ranking Jedi officers his "blunt opinion," he preferred to do things more diplomatically than the ARC troopers' bold orders. The clone captain led from the front, and in some cases would have fought ahead of General Anakin Skywalker. Rex was far from reckless, but his courage and willingness to jump into the fray helped the Republic 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, and his promise extended even to the ambitious Chairman Chi Cho.

Rex was loyal to the Republic and was visibly unsettled with Clone Sergeant Slick's betrayal and hatred of the Jedi. The clone captain was concerned for the safety of his Jedi officers, particularly those of Skywalker, Ahsoka Tano, and Obi-Wan Kenobi, whom he often served with throughout the war. Rex was hesitant to follow orders that put the Jedi in danger, especially those coming from the Jedi themselves. He 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. On Geonosis, Rex was adamant against "turning tail and running" with his men. However, the clone captain 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. Rex was both angered and saddened with the near-eradication of Torrent Company at Teth and the loss of troopers Vere and Ince during a rescue mission to JanFathal. After Vere's death, Rex pushed his anger to one side so that it would serve as fuel for the job at hand, intending to let it go later when no one could see him break down. The clone captain was surprised to find on JanFathal that his instinct was not to look after Tano, whom he usually guided, but to take care of his men.

Born to fight the "clankers" and "tinnies" of the Separatist Droid Army, Rex held the battle droids in contempt for the damage they had wrought on both him and his clone brethren. The clone captain understood his position as a clone trooper manufactured to fight for the Republic, and while he was aware that he and his clone brothers had been forced into the war without a choice, he made the best of the situation. Rex knew that politics and ideology of fighting were beyond his influence and instead focused on the day-to-day duties of looking out for his brothers in arms and "making sure he dropped the enemy before they dropped him." He stayed focused by keeping himself busy, taking advantage of the fact that clones "never fell short of tasks to complete." The clone captain did not allow himself to be intimidated by his enemies and even expressed humor in the direst situations. He was a practical strategist, taking the necessary measures and carefully identifying obstacles in a situation to ensure its success. A soldier's experience in battle mattered much to the veteran clone, and he often judged by one's experience instead of rank. In addressing the rookie troopers of the Rishi outpost, Rex made use of the derogatory "shinie" slang but was pleased when they grew to the challenge and recaptured the Republic base from the Confederacy.

Throughout the Clone Wars, Rex became acquainted with a number of his clone brethren. He was good friends with Clone Commander Cody, whom he worked with in several missions. Their relationship mirrored that of Skywalker and Kenobi&mdash;Cody admired Rex's superb instincts in battle, but like Kenobi's concerns for Skywalker, the clone commander worried that Rex put too much faith in them. After serving alongside ARF Sergeant Boomer many times, Rex came to both trust and befriend the clone trooper. Aboard Captain Pellaeon's Leveler, Rex found himself comfortable with others that were involved in the war and understood him. The trooper also admired the Republic civilian contractors' willingness to live or die by the quality of their workmanship. However, the captain found that he did not like a spacegoing navy, as he was privy to having ground under his boots. Rex had certain manners of etiquette that he strictly observed and respected, one of them being his troops' privacy. After the five rookie clones under his command had opened up their own comlink channel, the clone captain 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 case of an emergency.

Rex often made judgments based on what he was and was not trained on, respecting diplomatic negotiations as "a kind of fighting he was not trained for." He learned what he could from the Republic's HoloNet News bulletins and was used to absorbing information this way, as Kaminoan flash training had made up a large part of his early life. After meeting the pacifist Lurmen on Maridun, the clone captain could not understand their choice to avoid fighting, believing that they had no pride. Serving closely with Skywalker throughout the Clone Wars, Rex adopted the Jedi's unconventional and unorthodox combat tactics, and it was their similar lack of "by the book" methods that allowed the two to get along so well. Having served alongside Jedi Generals throughout the war, Rex had seen the Jedi in action and learned to both respect and never doubt their abilities. However, he sometimes disapproved how some of them preferred debating to fighting. The clone captain's own general, Skywalker, matched him in bravery, aggression, and decisiveness, and the Jedi's "soldiery" traits helped Rex to form "something of a friendship" with him.

Rex's time spent with Skywalker was such that the clone even became aware that the Jedi had feelings for Senator Amidala, although he was unaware of the full extent of their attachment. As a soldier, the clone captain was loyal to Skywalker both on the battlefield and at a personal level. When the Jedi was away, Rex kept him regularly updated with the current situation, aware of the consequences that his general would face for being caught "out of the loop." Rex was the first clone that Tano met on Christophsis, and the clone captain was concerned with Tano's initial naivety. After the two reached an understanding of each other, they began to form a strong bond in the continuing war. 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. The clone captain often addressed Tano as "kid." Skywalker trusted the clone captain with Tano, and as her Master, the Jedi also recognized that some of the Padawan's lessons were better learned from Rex. Rex helped Tano through several tough situations, including when Skywalker was injured on Maridun and on JanFathal when her beliefs in the Jedi Code were challenged, and also guided her in her first command position at Ryloth. Both supported the other, and their friendship as Jedi and clone trooper remained strong through the galactic Clone Wars.

Rex found hair under a helmet annoying and bothersome, and as such, he regularly shaved and used hair polish. Even so, the clone captain dyed his hair blond and let it grow out to a certain extent. At one point, he briefly dyed his hair blue to support the Bylluran Athletic bolo-ball team before deciding his new style was "undignified" for a commanding officer and shaving it to better fit in with his troops. Rex had a small scar beneath his lower lip.


 * Described by Pellaeon as a "solid, sensible chap" who also told "very good jokes when not playing the obedient soldier" (around Skywalker)
 * "Could shut out anything if he put his mind to it"; dealt with his doubts about his "programmed" service to the Republic as a clone trooper by inflicting the fact that the men under his command depended on him to lead them

Talents 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 Standard Basic. His natural abilities led him to be recommended for supplementary training on Kamino. With extra training and intensive programmed learning in addition to Kaminoan flash training, he was versed in a variety of tactics and fighting styles. The clone captain was capable of leading specialty clone units when the need arose. Like any good soldier, Rex knew his weapons, but also realized that gear alone would not win a battle. Aware that a soldier's mind 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, the clone captain 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 trained in blaster combat, and his skills in marksmanship were evidenced numerous times throughout the war. He was able to hit fast-moving and faraway targets. He reacted quickly to the appearance of a Rishi eel, firing at the large creature and killing it with a shot to the eye. Rex was also trained in close combat, displayed during a brawl with the turncoat clone Slick on Christophsis. Rex recognized that if he did not kill the droids of the Confederacy first, they would kill him, and his "casualty" in combat against the battle droids was noted by Skywalker during the Battle of Christophsis. Rex also displayed a certain smoothness in battle, cutting through his enemies without pause or hesitation whether his opponents were Separatist droids on Ryloth or Talz warriors on Orto Plutonia. The clone captain was able to hold his own against both the massive tri-droids and Vulture droid starfighters of the Separatist Droid Army, the latter of which he learned to dread even more than B2 super battle droids.

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 the Mandalorian Jaig eyes as battle honors, and it was also equipped with a fold-down, night vision–enabling rangefinder scope and a pair of removable headlamps with a viewing distance of 40 feet. He made use of a variety of tools: a vibroblade in one of his gauntlets, a comlink-equipped left gauntlet, a medpac in his utility belt, and a rappel line. Rex wore the traditional leather kama half kilt, made out of thick anti-blast armor, as well as a partially-blue pauldron over his left shoulder.

Rex sometimes wore generic white clone trooper armor. While on Orto Plutonia, the clone captain was forced to don cold-weather armor decorated with Jaig eyes with the inclusion of a rebreather hood and a thermal suit as protection from the cold. Although it was necessary for survival on the cold planet, the extra gear dangerously limited his movements in battle. Trained in marksmanship, the clone captain made use of a variety of weapons throughout the war. He mainly wielded a pair of DC-17 hand blasters, similar to the fighting style of Jango Fett, the bounty hunter whom he was cloned from. Rex sometimes used a DC-15S blaster and a DC-15A blaster rifle, and while on JanFathal, he used a DC-15 with a grenade launcher mod that the weapon "was not supposed to have." When the situation called for it, Rex made use of a JT-12 jetpack.

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

CC-7567 was created for the 2008 Star Wars: The Clone Wars film and television series, and first appeared in the film's novelization and junior novelization. As the series' primary clone character, Rex continues his role as a recurring clone character throughout the series' first and second seasons. He also appears extensively throughout media related to the series, including the comic series, graphic novellas, novel series, and young readers books, as well as the video games Jedi Alliance and Republic Heroes. Rex was offered as a character in Cartoon Network's online The Clone Wars Game Creator, which allowed players to create their own online mini-games and play those developed by others.

Voice actor Dee Bradley Baker provides Rex's voice throughout the series, as well as the voices of all other clone troopers. 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.

At first, the creators of The Clone Wars series decided to put in Alpha-17, the Advanced Recon Commando known from the Dark Horse comics, as the series' prime clone character. However, 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. Rex's chin scar is based on the blemish that actor Harrison Ford&mdash;who portrayed the smuggler Han Solo in the original Star Wars films&mdash;made famous in the Indiana Jones saga.

Merchandising
Rex was featured in the 2008 Clone Wars and Clone Wars Tactics expansions of the Star Wars PocketModel Trading Card Game, as well as the Galaxy at War expansion set of the Star Wars Miniatures series.
 * Featured on "Clone and Sky" packaging for 2010 SW merchandise

Inconsistencies
There have been numerous inconsistencies with Rex's rank. The 2009 Wizards of the Coast sourcebook The Clone Wars Campaign Guide, among other media, claims that Rex is a clone commander. This is supported by the Guide to the Grand Army of the Republic reference article published in the September 2005 issue of Star Wars Insider, which, if used, means that he would therefore be in charge of the 501st Legion. However, in the majority of sources that are 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 Clone Wars novel series, and many other sources&mdash;Rex is referred to as a clone trooper captain.

There have also been concerns with Rex's rank because the previously-published Guide to the Grand Army of the Republic states that if he was a captain, he would be in command of a company. However, the majority of all media directly related to the series claims that he is in charge of the 501st Legion. Therefore, this article assumes that Rex is a captain in command of the 501st Legion, although it is contradictory to the previous Guide to the Grand Army.

During Escape from Kadavo, Obi-Wan Kenobi addresses a clone trooper who is clearly wearing Rex's customized blue-and-white armor as "Cody." 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 presents different portrayals of Rex's roles in several episodes. 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. Skywalker eventually contacts the two troopers for assistance, and the pair find a control panel and use it to reactivate all systems in Sector AA-23. Rex and Denal successfully destroy the station's reactor and are ordered to rendezvous with the Jedi at the hangar so 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 open.

Rex and Denal arrive at the hangar bay, defeat a number of battle droids there, and prepare the Twilight for takeoff. Tano and R2 then arrive at the hangar, and the droid deactivates the first terminal. Traversing through the outer hull of Skytop Station, Skywalker reaches the second terminal and deactivates it as well, thus taking down the lockdown. He then makes his way to the Twilight, defeats several IG-86 sentinel droids that have pinned down Tano and the clones inside the ship, and opens the hangar doors. After Skywalker boards the Twilight, it takes off from the station. This portrayal of events opposes those featured in "Duel of the Droids," where the mission was first depicted.

The clone captain is also featured in a different mission that conflicts with the television series' first season episode "Lair of Grievous." Captain Rex and two other clone troopers assist Jedi Master Kit Fisto in infiltrating General Grievous's castle on the third moon of Vassek. Leaving the two clones outside, Fisto and Rex navigate through the lair's mazes and fight numerous B1 and B2 battle droids, eventually confronting the cyborg general 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 Clone Commander Fil does during the episode. The troopers, however, fail to complete their orders, as the 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 and is forced to retreat on his Delta-7B fighter.

Rex later participates in a mission to the space station Juma 9. Using Separatist clearance codes previously stolen from Grievous's lair on the Vassek moon, the clone captain 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 in to assist them. The clone captain 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 their way to Juma 9's bridge. Unduli and Koon are ultimately successful in completing their mission and taking over the bridge. 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, 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 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. The clone captain reports that the mission is proceeding as planned, but several B1 battle droids and an OG-9 homing spider droid appear. The spider droid bowls Rex over, and the captain 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. The clone captain explains to the scared trooper that it is a droid, not an actual spider, and Rex watched as the clone took 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 comes across a squad of IG-100 MagnaGuards and their Porax-38 starfighter, but a B2 super battle droid and several IG-227 Hailfire-class droid tank 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 soon appears with the Death Brick weapon and throws it at the three Jedi before escaping with the battle droids. Rex jumps in the line of fire and blocks the brick, which simply bounces off of his head. Commander Cody arrives with an LAAT/i gunship and transports Rex and the Jedi 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 has been jammed from the crash&mdash;in time, and the clone captain arrives with Jedi General 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. The clone captain is also present when Koon is given an award for his valiant efforts in the battle.

LEGO Star Wars: The Quest for R2-D2
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, Masters 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 forms a CR90 corvette. The Republic 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.
