Current project: CT-7567/Canon

"I know someone who might be able to help us. A great military commander with a vast knowledge of the Outer Rim. He could assist us in finding a base, and his experienced leadership would make him a powerful ally."

- Ahsoka Tano

CT-7567, nicknamed "Rex," was a veteran clone trooper captain in the Grand Army of the Republic's 501st Legion during the Clone Wars. Bred and trained for leadership on the planet Kamino, Rex began his military service at the Battle of Geonosis, which sparked warfare across the galaxy. He served as second-in-command to Jedi General Anakin Skywalker, whose valor and avant-garde abilities he soon adopted. He was also close friends with Commander Cody, with their relationship reflecting that of their Jedi Generals, Skywalker and Obi-Wan Kenobi. At the Battle of Christophsis, Rex became a mentor to Skywalker's new Padawan, Ahsoka Tano, with whom he formed a strong bond. He upheld his orders during the following Battle of Teth despite numerous casualties in his 501st unit, Torrent Company, and later helped Cody rally a team of rookie soldiers to retake Rishi Station. He partook in countless campaigns against the Confederacy of Independent Systems, from the containment of a virus outbreak on Naboo to other pivotal victories on Ryloth, Malastare, Geonosis, and Kamino, all the while earning exemplary status within the Grand Army.

Rex was loyal to his Jedi officers as well as the soldiers under his command, even as his military service raised doubts about his future&mdash;and that of his clone brethren&mdash;in the Republic. A campaign on Saleucami led him to cross paths with the clone deserter Cut Lawquane, who earned his respect despite their striking differences. The Battle of Umbara strained his leadership and obedience to orders, as he strove to unite the 501st Legion under an interim Jedi General, Pong Krell. When Krell proved to be a traitor to the Republic, Rex risked charges of treason to lead his men in arresting Krell. Rex contributed to the war effort in various ways, whether by helping the Jedi train the Onderon rebels to liberate their world or by developing a strategy algorithm to optimize the Republic's frontline tactics. Yet in a stark turn of events, he and Skywalker apprehended Tano after she was framed for a bombing of the Jedi Temple, an incident that led to her departure from the Jedi Order. In addition, the Separatist-loyal Techno Union acquired Rex's strategy algorithm via the missing ARC trooper Echo, leading Rex to mount a rescue mission with the aid of the Bad Batch.

Toward the end of the Clone Wars, Rex had his inhibitor chip removed due to an anti-Jedi conspiracy that his late comrade Fives had uncovered. He was thus able to avoid executing Order 66, which triggered a galaxy-wide genocide of the Jedi. As the Republic was reconstituted into the Galactic Empire, Rex retired from military service and settled on the planet Seelos with fellow veterans Wolffe and Gregor, hunting joopas and pondering the purpose of the war. Over a decade later, a band of rebels from Lothal convinced Rex to become part of a network of rebel cells that Tano facilitated. As a result, Rex joined the rebels aboard their starship, the Ghost, where he served as a mentor to Jedi-in-training Ezra Bridger while developing a difficult friendship with Bridger's Master, Kanan Jarrus.

Captain in the 501st
"He's wound tight, but he's loyal.''" "He kind of reminds me of you." "''Maybe&hellip; back in the day."

- Rex and Anakin Skywalker, on rookie trooper Dogma

Born approximately thirty-two years before the Battle of Yavin on the remote planet Kamino, CT-7567 was one of the thousands of human clones who were decanted from the reputed bounty hunter Jango Fett, intended for military service in the Grand Army of the Republic. As part of the Kaminoans' cloning process, CT-7567 and his brethren were subjected to growth acceleration, aging at twice the normal rate for humans. At the embryonic stage of a clone's growth cycle, an inhibitor chip was installed within each clone to make him less aggressive and more compliant to orders. Like the rest of his clone brothers, CT-7567 was implanted with an inhibitor chip, though he remained unaware of its existence and purpose. He was bred for leadership and received advanced tactical and additional command training while on Kamino. Eventually, he took the nickname "Rex" and earned the rank of captain. He consequently received command of Torrent Company, a unit within the Grand Army's 501st Legion.

Only a decade after the initiation of the Grand Army program, Rex was among the first generation of 200,000 clone troopers who were ready for active duty. That year, the Galactic Republic commissioned the Clone Army to combat the forces of the separatist Confederacy of Independent Systems on the planet Geonosis. In the ensuing Battle of Geonosis, Rex led his troopers in Torrent Company against the Separatist Droid Army, fighting alongside other clone units led by Jedi officers. He and his men fought well, contributing to the Republic's victory on Geonosis and achieving veteran status within the Grand Army. As conflict erupted across the galaxy, Rex and the 501st were assigned to Jedi General Anakin Skywalker, a rather unorthodox leader who nevertheless earned Rex's respect. According to Skywalker, Rex, as a rookie trooper, was prone to by-the-book behavior and was eager to follow every order to the letter, but he became less wound tight over time.

Among his comrades in the Grand Army, Rex became friends with clone marshal commander CC-2224, nicknamed "Cody," and collaborated with him in a host of military campaigns, including a botched operation on Tibrin alongside several Jedi.

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

- Rex, to Ahsoka Tano, during the battle in the city

Not long after the Battle of Geonosis, Rex joined Skywalker on a campaign to liberate the planet Christophsis, which had fallen to the Confederacy. Accompanying Rex and his comrades to Christophsis were Cody and his own Jedi General, Obi-Wan Kenobi. After breaching the Confederate Admiral Trench's orbital blockade, the Republic forces established a base on the planet's surface. Skywalker and Kenobi then brought a clone contingent led by Rex and Cody into a city to ambush the enemy battle droid forces. After locating a large complex with towers facing the north and south, Rex and Skywalker stationed their men on the forty-sixth level of the north tower, while that of the south tower housed Kenobi and Cody's detachment. The Jedi and clones intended to target a battalion of droids once it passed through the major plaza below the towers. Yet, upon the droid battalion's scheduled arrival, the enemy infantry unexpectedly divided into several columns, with squads of B1 battle droids surprising Kenobi's troops in the south tower. Upon learning from Kenobi that his position was compromised, Skywalker signaled clone trooper pilot Hawk for an extraction from the south tower, then immediately rappelled over there with Rex and their men using their DC-15 blaster rifles' ascension cables.

Regrouping with Kenobi and Cody, Rex and Skywalker rushed into a turbolift with their combined forces, emerging on the roof of the south tower. The battle droids were not far behind, reaching the roof via the building's other turbolifts. While Rex and his soldiers held position at the edge of the roof and focused their blasterfire on the droids, Skywalker and Kenobi fended off the Separatist units at a closer range. Hawk soon arrived aboard his LAAT/i gunship to airlift the Republic detachment to safety. Just before escaping with the others, trooper Gus snatched the cranial unit of TJ-55, the enemy T-series tactical droid commander, in the hopes that his memory bank would shed light on how the Separatists had acquired the Republic's battle strategy. That night, Rex and Cody used the base's command center to perform a robolobotomy on TJ-55's head, but the unit merely confirmed the Separatists had been aware of the clone troopers' location before malfunctioning.

Still baffled by the source of the Separatists' pilfered intelligence, Rex and Cody reported their limited findings to Skywalker and Kenobi. While Skywalker believed a security breach was the cause of their problems, Kenobi went a step further, deducing that a spy within their forces had informed the Separatists of their plan of attack. Skywalker and Kenobi decided to embark on a covert mission to gather information behind enemy lines, leaving Rex and Cody to find and expose the potential spy. Just after the Jedi's departure, Cody was alarmed to find that one of the comlinks on a nearby table had been intentionally left activated, indicating that someone had remotely eavesdropped on their entire conversation with the Jedi. Looking out into the hallway, Rex sighted a figure hiding in the shadows. Though too far away to be identified, it was Clone Sergeant Slick. Rex and Cody gave chase to the runner, and although Slick escaped without being recognized, the network of the base's hallways led the two officers to follow the fugitive's path to the mess hall. There, they found that the only people inside were clone troopers, making it apparent that the enemy spy was one of their brethren.

Though dismayed that one of their comrades was the traitor, Rex and Cody were determined to root out the spy. Cody tried to apprise Kenobi of their discovery but found that their communications were being jammed&mdash;cut off from the Jedi, he and Rex were on their own. Using Skywalker's astromech droid, R2-D2, to sift through the records of outgoing transmissions at the entire base, Rex traced an irregularity in wavelength interference to a computer terminal at the barracks that housed Slick's men. Inferring that one of Slick's charges was the culprit, Rex and Cody proceeded to the barracks to interrogate Slick's men regarding their whereabouts earlier that night, ignoring protest from Slick. Troopers Jester, Punch, Sketch, and Gus all passed their questioning with credible and corroborated alibis, but when Chopper was pressured into divulging that he had broken war protocols by stringing together a necklace of battle droid fingers, Slick tried to incriminate his subordinate in order to avoid detection as the spy. In doing so, he revealed he was aware that the Jedi were off-site&mdash;knowledge to which he was not supposed to be privy. When put on the spot, Slick bowled over Cody and Chopper and fled from the barracks, exposing himself as the traitor and leaving behind shock and dismay in his wake.

Initiating a manhunt for the fugitive Slick, Rex and Cody scoured the base, tracing a signal from his utility belt to the gunship landing platform. Though Cody believed that Slick was looking to escape, he was proven wrong when, instead of Slick, they found his utility belt linked to a primed thermal detonator. The pair of officers jumped clear just as the explosive detonated. Slick's sabotage laid waste to the parked AT-TE walkers and the weapons depot, as well as the base's power system. Amidst the fires blazing across the landing platform, Rex and Cody received word from Gus that Slick had been spotted running into the command center. Ordering Gus and the rest of their men to cordon off the base's perimeter, Rex and Cody entered the command center to apprehend the enemy agent. Upon noticing that Slick was hiding in the ventilation shaft, the two officers engaged in a ploy to bait the sergeant out of his hiding place. While Rex appeared to leave for the south exit, Cody remained behind to restart the base's power, planting his DC-15A blaster on the main console as bait. Rex re-entered the command center once Cody had retrieved his firearm from Slick, who had forsook his cover to steal it, and both officers held the fugitive clone at gunpoint.

The standoff between the three officers quickly escalated when Slick disarmed Rex of his DC-15A, kicked Cody in the head, and made a break for the exit. As a brawl began between Slick and Cody, Rex pulled the former off the latter, accusing the sergeant of taking payoffs from the Separatists as compensation for betraying his brothers. Not to be deterred, Slick knocked Rex off his feet and summarily dislocated his left leg, claiming that he had achieved freedom in his work, espionage and otherwise, for the Confederacy. Yet, Cody thereafter knocked Slick unconscious, and the subdued sergeant was locked in binders and brought before Skywalker and Kenobi once they returned to the base. Though Slick accused the Jedi of enslaving his fellow clones as soldiers for their cause, Rex and Cody asserted that he had betrayed his clone brethren&mdash;whom he professed to love&mdash;and placed them in harm's way by aiding the Separatists. Once Slick was marched off to lock-up, Rex and Cody reported to Skywalker and Kenobi that aside from the AV-7 Anti-vehicle Artillery Cannons, they had been unable to salvage their scorched supply of weaponry. In turn, the Jedi, having encountered Sith operative Asajj Ventress during their foray, relayed their discovery that the Separatists' on-world invasion force was thousands of droids strong.

Rex and his allies set up base in the city, which was thereafter besieged by the Confederate invasion force under the command of General Whorm Loathsom. The Republic forces won a victory over Loathsom's droids, though the interval in combat did not last long. When Loathsom's next wave of infantry arrived, Kenobi and Cody took up positions with the main detachment of troops at the city center, while Rex and Skywalker led a small team of troopers to rout the advancing column of battle droids from behind. Scaling a building that overlooked the main street through with the droids were marching, Rex and his men targeted the trio of octuptarra combat tri-droids at the rear of the enemy ranks. He and his troops used jetpacks to descend to street level and ambush one of the tri-droids, while Skywalker landed on another one. Their combined efforts brought down the three monstrosities, and the AV-7 Anti-vehicle Cannons further decimated the battle droids, forcing Loathsom to order another retreat. During the lull in fighting that followed, Rex joined the Republic's scouts at the lookout post to monitor the enemy's movements.

Skywalker soon arrived at the observation post with a Togruta youngling in tow, and Rex reported that Loathsom was preparing another assault on their defenses. When Rex questioned who the youngling was, she introduced herself as Ahsoka Tano, Skywalker's new Padawan learner, who had arrived aboard a Nu-class transport. Though a bit confused due to Skywalker's previous vehemence against taking a Padawan, Rex let out a laugh when she nicknamed her new Master "Skyguy." Skywalker, however, was less than amused with Tano's snippy behavior and had Rex give her a lesson in respect; he complied and brought her along to inspect the heavy cannons. Though Tano suggested that the cannons would have better cover if moved back, Rex stood by Skywalker's decision for the contrary. He conveyed his belief that there was no replacement for experience, not even a superior rank within the chain of command. Tano acquiesced, resolving to attain some experience herself.

In the distance, Tano noticed an expanding deflector shield that the Separatists had deployed, a development that alarmed Rex. The two of them joined Skywalker and Kenobi at the city center to plan their defensive strategy in light of the approaching deflector shield. Because Loathsom was advancing his forces just behind the shield's diameter, Rex noted that the heavy cannons would be useless. Furthermore, the clone soldiers' ability to street fight would be significantly limited without the heavy cannons. Skywalker decided to undertake the task of destroying the shield generator, taking his new Padawan on their first mission together. Rex, meanwhile, worked with Kenobi to marshal their troops in defense of the city center. As the droid infantry approached their position, Rex and Kenobi had the heavy cannons open fire on the shield. Monitoring the cannonade via macrobinoculars, the two officers confirmed that even at full power, the cannons' blasts were indeed ineffective against the shield.

As the shield passed over them, Rex fell back with his troops, luring the battle droids into the nearby buildings so as to level the playing field. However, the clone troopers continued to lose ground to the enemy infantry, which decimated the majority of Rex's unit and forced him and the survivors to retreat to Kenobi's position in one of the buildings. With the shield on the verge of reaching the heavy cannons, Kenobi tasked Rex and his men with defending their artillery, resolving to delay the droids on his own. Though Rex protested to such a course of action, he reluctantly complied and retreated with the rest of the troops while Kenobi covered their escape. Once Rex arrived at the cannons, he and his men concentrated their blasterfire on the inbound battle droids and Armored Assault Tanks, using the overturned crystalline rubble as cover. Due to their far superior numbers, the droids unleashed a brutal onslaught on Rex's troopers, who endured a number of casualties. Despite receiving word that Kenobi had been captured, Rex refused to waver in his commitment to their assignment, rallying his men in defense of the heavy cannons.

Kenobi had in fact surrendered to Loathsom as a stalling tactic, giving Skywalker and Tano enough time to sabotage the shield generator. Rex soon caught sight of the dissipating shield and immediately ordered the heavy cannons to commence firing on the exposed droids and Armored Assault Tanks, which they did to great effect. Admiral Wullf Yularen, having driven the armada from the Separatist navy away from Christophsis, dispatched an Acclamator-class assault ship and a squadron of gunships to ferry reinforcements to the beleaguered troops on the surface. Rex boarded one of the gunships and proceeded to the Separatists' shield generator site, where he picked up Skywalker and Tano. As they lifted off, Rex congratulated both Jedi on a job well done, particularly the young Tano, who was slowly earning his respect.

Rex's gunship dropped off Skywalker and Tano at the Republic's staging area, where they met with Kenobi and Jedi Grand Master Yoda, the latter of whom had arrived with Yularen's fleet, to receive their next assignments. The Republic's infantry reinforcements, meanwhile, assumed the task of securing Christophsis, bringing the Battle of Christophsis to a close.

Battle of Teth
"Captain Rex, this is General Skywalker.''" "Yes, General." "We're not going to be able to help you." "''Don't worry about us, General. We'll be all right. The mission always comes first, sir."

- Anakin Skywalker and Rex

Rex's next assignment took him to the Wild Space world of Teth. Renegades had kidnapped Rotta the Huttlet, the son of crime lord Jabba Desilijic Tiure, who thus requested the Republic's aid in rescuing his progeny. That task fell to Rex, Skywalker, and Tano, as the Republic hoped to convince Jabba to grant the Grand Army access to hyperspace routes that passed through Hutt Space. En route to Teth&mdash;where Republic scouts had located the Huttlet&mdash;aboard an Acclamator-class transport, Rex and several other troopers gathered in the hangar bay, where Tano recounted how she and Skywalker had eliminated the shield generator back on Christophsis. At Skywalker's behest, Rex ordered the troops back to their stations as they prepared for their operation. Because the clifftop B'omarr Order Monastery where Rotta was being held was heavily fortified, Skywalker decided to deploy their strike team in the forest below and then launch a vertical assault up the cliff face. Rex, Skywalker, and Tano thus departed with Torrent Company aboard a squadron of gunships, with LAAT carriers ferrying a pair of AT-TE walkers. Along the way to Teth's surface, Skywalker learned from Kenobi, who was in the middle of negotiations with Jabba on Tatooine, that they had a single rotation to retrieve Rotta and return him home safely.

As the gunships neared the cliff, the monastery's defenses opened fire on the incoming craft, which soon touched down in the jungle below. Rex and the others disembarked and ducked beneath an overhang for cover. Following Skywalker and Tano's lead, Rex and the men of Torrent Company used their ascension cables to scale the cliff. As a vertical crossfire commenced between the Republic infantry and the monastery's battle droid defenders, the enemy cannonades felled one of the AT-TE walkers. Undeterred, Rex kept pace with Skywalker until B1 battle droids flew in on Single Trooper Aerial Platforms to assail Torrent Company mid-climb. Skywalker commandeered one of the repulsorcraft and disabled the others, ordering Rex to follow as he soared to the top of the cliff. Torrent Company reached the monastery and obliterated the rest of the droids, though not without casualties. Once his troops confirmed that the stronghold was clear, Rex assigned some men to look after their wounded, and also reported to Skywalker that their gunships were holding position at a safe distance from the stronghold.

Because the high quantity of battle droids indicated that Rotta's kidnappers were not renegades, Skywalker deduced that the Separatists were responsible for the abduction. While Torrent Company remained outside, Rex accompanied Skywalker, Tano, and a squad of troopers to enter the monastery. Inside, Rex and his soldiers activated their helmet's headlamps for better vision in the dimly lit antechamber, keeping their blasters raised in case of danger. The Jedi and clones happened upon the protocol droid 4-A7, who introduced himself as the monastery's caretaker and thanked them for liberating him from the battle droids. Unbeknownst to them, 4-A7 was a spy for Separatist agent Asajj Ventress and meant to incriminate the Jedi as the Huttlet's abductors. Upon learning from 4-A7 that the droids had kept their prisoners on the detention level, Skywalker and Tano proceeded there, while Rex returned to the courtyard and finished securing the castle with his troops. As it neared midday, Skywalker and Tano returned with the Huttlet, who they soon discovered was afflicted with a fever.

While Skywalker and Tano were delivering a status update to Kenobi via R2-D2's holoprojector, a pair of C-9979 landing craft entered the monastery's airspace alongside squadrons of vulture droid starfighters. Rex and his men opened fire on the droid starfighters, which occupied their attention long enough for one of the landing craft to land at the monastery. The ship disgorged a number of B1, B2, and DSD1 dwarf spider droids that swarmed into the courtyard, cutting off the clone troops' chance of escape. Rex and his comrades retreated into the monastery, enduring more casualties along with the loss of their final AT-TE walker before they sealed the stronghold's door, barricading themselves inside. While Skywalker and Tano departed with R2-D2 and Rotta to find another exit from the castle, Rex remained in the entrance chamber with Torrent Company to hold off the Separatists. Not long after he and his soldiers took up positions along the walls, the Separatist battalion&mdash;under the command of Asajj Ventress&mdash;disabled the door's lock mechanism, flooding into the stronghold in rising numbers. The resulting slaughter was swift: Save for Rex and a few of his comrades, Torrent Company was annihilated.

Feigning death, Rex watched as Ventress entered the antechamber and conferred with one of her droid commanders. Furtively raising one of his DC-17 hand blasters, he gunned down the droid commander and targeted Ventress. She immediately drew her lightsabers and deflected his blaster shots, then used the Force to telekinetically disarm him of his blaster pistol. Ventress Force-choked him and demanded to know Skywalker's whereabouts, but Rex resisted her interrogation, even when she performed a mind trick on him and ordered him to ask Skywalker for his location. Instead of succumbing to her mental influence, Rex contacted Skywalker of his own accord, addressing him as "Anakin" in lieu of his usual "General Skywalker" to allude to Ventress's presence. Unaware of his exploit, Ventress went after Skywalker and the Huttlet, leaving her battle droids in charge of the clone survivors. Rex and his comrades were rounded up and held at blasterpoint, though not for long. When Skywalker contacted him via comlink, Rex was unable to answer, but the call drew the attention of one of the battle droids. As soon as the droid was close enough, Rex swatted his head and grabbed the reeling droid's E-5 blaster rifle, claiming the sidearm for himself.

The Torrent Company survivors followed Rex's lead, breaking free from their droid captors and pilfering their blaster rifles. As he and his comrades found cover behind the fallen AT-TE walker, Rex finally responded to Skywalker, who inquired whether he required assistance. Instead of replying, Rex took the opportunity to return the droids' oncoming blasterfire. After bringing down an inbound vulture droid in walking mode, Rex and his comrades abandoned the fallen AT-TE and sprinted over to the fallen droid starfighter, using it as cover to engage the enemy units at a closer proximity. Yet, the clones were seriously outnumbered, and the battle droids demanded their surrender. At that moment, Kenobi arrived at Teth with Commander Cody and a detachment of troops. Swooping in aboard his Delta-7B starfighter, Kenobi somersaulted out of his starship to reinforce Rex and the remainder of Torrent Company, while LAAT/i gunships deployed Cody and his men. Taking up a DC-15 blaster rifle to contend with the battle droids, Rex reported to Kenobi that Skywalker was likely still inside the castle, and the Jedi Master left to find him.

Presently, Skywalker&mdash;who had hijacked the old spice freighter Twilight with Tano and Rotta&mdash;contacted Rex to reluctantly inform him that they would be unable to provide support, since returning Rotta to his father was still their priority. Rex understood Skywalker's dilemma and assured him that they could manage without him. When a dwarf spider droid entered the clones' vicinity, Rex had his men provide covering fire and charged at the droid. He swiftly planted a primed thermal detonator in its undercarriage, jumping away to avoid the explosion that engulfed it. Kenobi thereafter returned to the courtyard, having dueled Ventress and forced her to retreat. Rex voiced his doubt that Skywalker and Tano would be able to reach Tatooine in their battered freighter, but Kenobi was confident that Skywalker's expertise at a starship's controls would prove adequate. After the conclusion of hostilities on Teth, Rex and Cody accompanied Masters Yoda and Kenobi to Jabba's Palace on Tatooine to retrieve Skywalker and Tano, who had safely delivered Rotta to his father and established the Republic's long-awaited treaty with the Hutt Clan.

Outpost inspection tour
"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

During the emergence of a new Separatist superweapon, Rex was stationed with Skywalker and Tano aboard the former's flagship, the Venator-class Star Destroyer Resolute, when it was deployed with the rest of Skywalker's fleet to the Bith system. After the enemy weapon inflicted a devastating assault on Jedi General Plo Koon's flotilla in the nearby Abregado system, the Resolute was sent to safeguard the Republic's convoy ships alongside Kenobi and the rest of their armada. Skywalker thereafter divided his fleet to increase their defensive perimeter and, under the pretense of scouting ahead for enemy activity, departed with Tano to search the Abregado system for survivors of the assault, in direct violation of orders from the Jedi High Council.

Rex was present with Admiral Yularen on the Resolute bridge when Kenobi contacted them to check on their progress as well as Skywalker's whereabouts. Yularen stated that the convoys were on schedule and also relayed Skywalker's orders. Skywalker and Tano soon discovered that the enemy's mystery weapon was the Malevolence, a colossal Subjugator-class heavy cruiser that was equipped with an ion cannon, and rescued Koon and the few soldiers who had survived their fleet's destruction. The Resolute was again reassigned, this time to join a Republic Navy offensive on the Malevolence near the Kaliida Nebula. The resulting Battle of the Kaliida Nebula saw the battleship eradicated, terminating its threat to the Republic.

Over the next few weeks, Rex and Cody were assigned to conduct an inspection tour of the Republic's listening posts. After they visited a tracking station at Pastil and confirmed it was operational, Cody reported their progress to Skywalker and Kenobi, who were aboard the Resolute carrying out a search for the Confederacy's elusive military commander, General Grievous. Rex and Cody then departed for Rishi Station, an outpost situated on a moon in the Rishi system. The station was of particular importance because it served as one of the last lines of defense for Kamino, which had become a strategic target for the Confederacy. As they arrived in the Rishi system aboard the attack shuttle Obex, Cody hailed Rishi Station to announce their imminent landing. Yet, he and Rex were unaware that a squad of Confederate BX-series droid commandos had overrun the base. When a droid commando posing as a clone trooper answered the transmission, Rex gleaned from the trooper's droid-like responses that something was amiss. Nevertheless, Cody placed him in charge of the inspection, and they continued to the moon.

Touching down at the station's landing pad, Cody noticed the station's lack of an on-duty deck officer, a flaw that Rex found to be sloppy. A droid commando disguised in clone armor greeted them and tried to convince them that the outpost did not require an inspection, but when Rex spotted a droid attack flare launched from behind them, he summarily sent a blast from his DC-17 blaster pistol straight through the trooper's head. Though Cody was shocked with his brazen behavior, Rex removed his victim's helmet to reveal the disabled droid underneath. At that moment, the two officers came under fire from droid commandos that had been hiding around the landing platform. Diving behind some nearby crates for cover, Rex and Cody had little opportunity to return the droids' blasterfire before their opponents tossed a batch of thermal detonators at the Obex. The pair of officers managed to escape from the ensuing explosion by jumping off the platform and using their ascension cables to rappel to the canyon below; the droids, meanwhile, assumed they had perished in the explosion.

With the loss of the Obex, Rex and Cody were stranded on the moon, a situation that reminded them of their time on Tibrin. They came across the only survivors of the droid incursion: rookie soldiers CT-27-5555, CT-782, and CT-1409, nicknamed "Fives," "Hevy," and "Echo," respectively. Rex immediately ordered the three of them to remove their helmets in order to confirm they were clone troopers. Just after they had done so, a Rishi eel emerged from an adjacent crevice; Rex impressed the rookie soldiers by felling the predatory eel with a single blaster shot to the eye. Exchanging introductions with their new charges, Rex and Cody learned that their sergeant, O'Niner, had been among the casualties of the earlier attack. Rex labelled the three troopers as "shinies," a derogatory term for their inexperience on the battlefield that manifested in their pristine armor, and placed a handprint of the fallen eel's blood on Echo's armor. When Hevy voiced the rookies' determination to retake the base regardless of their "shinie" status, Rex remarked that there was hope for them yet.

As Rex and the others climbed up the canyon wall to Rishi Station, he and Cody offered their DC-15A blasters to the rookie soldiers. Rex devised a plan to gain access to the enemy-held base, posing as Commando Unit 26 in clone armor and mechanically walking up to the blast doors' surveillance system. Conferring with the trio of droids that were on surveillance duty inside the entrance, he maintained his cover by pretending to adjust his "vocabulator" and using an inert droid commando head when the guards demanded visual verification of his identity. Though the unorthodox tactic elicited a facepalm from Cody, it worked, and the droids admitted Rex entry. Once he and the others gunned down the three guards with celerity, Rex&mdash;taking the lead position despite Hevy's request for it&mdash;spearheaded the assault on the droids in the command center. Rex eliminated several of the droids manning the central computer before the droid commando captain pounced on him from a higher level. Undaunted, he dodged the droid's vibroblade slashes and snapped the droid's neck with his gloved hands.

Though Rex and his comrades prevailed over the droid commandos, their success was short-lived. The team of five learned that a Separatist naval detachment&mdash;led by General Grievous&mdash;was passing over the moon, and they realized the droids had severed the station's communication system and hot-wired the all-clear signal to conceal the impending invasion from the Republic. Upon receiving no response from the droid commandos, Grievous dispatched a C-9979 landing craft, which brought droid infantry reinforcements to the base. When Cody noted their slim odds for success, Rex decided that they had to destroy Rishi Station. Despite the plan's lack of convention, the consequent cessation of the all-clear signal would complete the troopers' primary objective: to alert the Republic to the invasion. Echo contributed to Rex's plan, proposing that they repurpose the station's supply of liquid Tibanna fuel as explosives to liquidate the facility. Before they initiated the operation, Rex and Cody spoke with Fives, Echo, and Hevy to prepare them for the forthcoming battle. Because the Confederacy's target could only be Kamino, Rex rallied the rookies with the knowledge that they were defending not only the Republic, but also all of their brethren back home on Kamino.

While Cody, Hevy, and Fives launched a diversionary assault on the battle droids at the outpost's entrance, Rex and Echo ushered several PLNK-series power droids, containing the liquid Tibanna, into the command center. As they wired the three power droids together, Rex was unable to link the datapad handset to the detonator. At Rex's behest, Hevy stayed behind to repair the remote while the others evacuated from the base via a maintenance pipe. Rex assumed that Hevy had promptly fixed the remote and was right behind them, but when he told Hevy to detonate the explosives, he and the others discovered that Hevy had not yet joined them. Rex contacted Hevy via comlink and ordered him to vacate the base, but the trooper refused, stating that he would have to manually detonate the charges on account of the defective remote. Though Rex and the others backtracked to help their comrade, Hevy sacrificed himself to activate the explosives, demolishing the outpost and fulfilling their main objective. As Rex and his comrades took cover from the falling debris, Echo soberly remarked that Hevy had always hated Rishi Station.

Hevy's termination of the all-clear signal triggered an immediate response from Skywalker and Kenobi, who arrived with the Republic fleet and drove Grievous's armada out of the system. LAAT/i gunships collected Rex, Cody, Fives, and Echo from the moon and ferried them to the Resolute. In a ceremony in the Star Destroyer's hangar, Skywalker and Kenobi commended Echo and Fives for their valor, personally awarding them medals, and also honored Hevy's heroism. Rex, impressed by the efforts of the former "shinies," inducted Echo and Fives into the 501st Legion.

Bothawui and its aftermath
"Ahsoka, they're in position. Unveil our little surprise.''" "Right away Master. Rex, old boy, it's time you joined the party." "''With pleasure, sir."

- Anakin Skywalker and Ahsoka Tano order Rex to open fire with their hidden AT-TE walkers in the Bothawui asteroid belt

Rex remained aboard the Resolute when Skywalker's fleet was tasked with defending the strategic world of Bothawui from Confederate invasion. At Bothawui, Skywalker positioned his three-cruiser armada between the planet and its surrounding asteroid field to await an incoming Separatist fleet, commanded by General Grievous. Rex was on the Resolute bridge with Skywalker and Tano when Kenobi holographically reported that Grievous had just overrun a Republic battle group stationed at the planet Falleen. Though Kenobi advised Skywalker to retreat from Bothawui due to Grievous's far larger assault force, Skywalker was adamant against doing so, lest the Separatists claim control of the surrounding sector. As part of his defensive strategy, Skywalker dispatched Rex and a detachment of AT-TE walkers to hide in the asteroid field, where they would set a trap for Grievous&mdash;the cover of the asteroids would enable the AT-TEs to outflank Grievous's fleet after it passed through the field. Skywalker, meanwhile, would lead a starfighter assault with Gold Squadron, while Tano assumed command of the Resolute in the interim.

Once Grievous's fleet of six Munificent-class star frigates had arrived at Bothawui, passed through the asteroids, and opened fire on Skywalker's cruisers, Rex and his gunners initiated their offensive, quickly turning the tide of the battle. Their surprise attack was all the more effective because the unsuspecting Grievous had diverted his frigates' power to their forward shields, exposing their aft sections to cannonades from Rex's AT-TE walkers. As Grievous's frigates crumbled one after another, the enemy general escaped from his crippled fleet in his personal starfighter, Soulless One. Though Skywalker gave chase in his own Delta-7B starfighter, shrapnel from one of the disintegrated frigates caused damage to his interceptor, sending it uncontrollably toward the asteroid belt. Rex managed to rescue Skywalker from his disabled starfighter but could not save R2-D2, who had served as the Jedi General's astromech co-pilot. Rex and Tano were present when Skywalker awoke in the Resolute medical bay; they relayed to him the battle's success as well as the loss of R2-D2.

After conducting an unsuccessful search for R2-D2 in Bothawui's asteroid belt, Skywalker and Tano returned to the Resolute. Their next assignment from Kenobi was to track down and eliminate a new Confederate listening post that&mdash;according to the Republic's intelligence&mdash;was intercepting Grand Army transmissions, thus enabling enemy access to their broadcasts. Skywalker elected to personally patrol the outer corridor of a targeted area of space, while the Resolute and the remainder of their forces concentrated on the center of the region. Though Rex questioned whether Skywalker was sure about performing reconnaissance alone, Skywalker was convinced that more than one starship would attract too much Confederate attention. The Jedi General thus departed on his mission aboard his retrieved Delta-7B starfighter, accompanied only by his replacement astromech droid, R3-S6, who was secretly a double agent for Grievous.

Soon after Skywalker's departure, Tano found that his starfighter's homing beacon had been activated, indicating that his position was compromised. Rex hurriedly assembled a squad of troopers to reinforce Skywalker, and they departed with Tano aboard the Twilight. Rex and the others arrived out of hyperspace at Skywalker's location to find him in mid-battle with Grievous, who had ambushed him with a pair of Munificent-class star frigates and a full squadron of vulture droid starfighters. Since enemy fire had reduced his hyperspace transport ring to smithereens, Skywalker piloted his starfighter into the Twilight cargo bay so that they could retreat together. With Rex and his soldiers manning the Twilight laser cannons, Tano maneuvered the freighter through the narrow gap between the enemy frigates' adjacent wings. As soon as they were clear, Rex engaged the Twilight hyperdrive, engineering a successful escape from Grievous.

Instead of returning to the Resolute and the rest of the fleet, Rex and the team stayed aboard the Twilight to scour nearby space for Grievous's secret listening post. It was not long before they received a transmission that, according to Skywalker, contained R2-D2's recognizable beeps and whistles. Though Tano doubted it was R2-D2, Skywalker ordered Rex to trace the origin of the broadcast. Rex's coordinates brought them to the Ruusan system, where they made a critical find: Skytop Station, the enemy base they had been searching for. The station, a converted core ship, hovered in the upper atmosphere of one of the planet Ruusan's three moons. When Skywalker reported their discovery to Kenobi, he opposed his fellow general's intent to send a pair of cruisers to destroy Skytop Station, since Skywalker believed that R2-D2 was aboard the station. In spite of Kenobi's orders for the contrary, Skywalker was determined to mount a dual operation to sabotage the outpost and save his missing astromech. As they prepared to depart, Tano informed Rex that he would be carrying R3-S6&mdash;whom the strike team needed to slice into the base's computers&mdash;during their insertion drop, a task that he did not find appealing.

Once the Twilight entered the upper portion of the moon's gassy atmosphere, Rex and his four troopers followed Skywalker and Tano in free-falling to Skytop Station many meters below. Rex and his soldiers used jetpacks to check their descent, while the two Jedi relied on the Force to do so themselves. Upon landing with the heavy R3-S6 in his arms, Rex told his men that they would be responsible for carrying the astromech next time. He and the strike team entered the station, disposing of a pair of B1 battle droids in their path. Stopping in one of the hallways, R3-S6 plugged into a computer terminal and accessed the battlesphere's holographic schematics, which Rex used to determine that the reactors were thirty levels below their entry point. While Skywalker separated from the team in search of R2-D2, Rex proceeded with Tano and their four soldiers to plant explosives at the reactors, the destruction of which would cripple the station's repulsorlifts, thus enabling the moon's gravity to bring down the entire facility. When they reached the reactor room, Rex and his comrades found that an alarm had activated an additional security door in the form of a ray shield. Though R3-S6 began to slice into the ray shield's controls, the sounds of an approaching squad of battle droids caused Rex to doubt that the astromech would succeed in time. Despite Tano's belief in R3-S6's capability, the droid was in fact stalling to give the inbound droid squads enough time to reach the strike team's position.

A squad of battle droids arrived at both ends of the corridor, capturing Rex and his comrades in a crossfire. At Tano's behest, Rex tossed an Electro Magnetic Pulse grenade&mdash;nicknamed the "droid popper"&mdash;in both directions, disabling their mechanical adversaries. Yet, the strike team was immediately faced with another problem: Grievous. The cyborg general arrived and shoved Tano aside with relative ease, then turned his attention on the clone troopers. Rex and his soldiers bombarded Grievous with blasterfire but were unable to land clean shots. Only Rex and another trooper, Denal, survived Grievous's ensuing attack, and both men were knocked unconscious. Just as Grievous raised one of his lightsabers to kill the inert Rex, Tano intervened, blocking the cyborg's strike with her own lightsaber. When Rex and Denal awoke, Tano and Grievous were gone, and Rex learned from Tano via comlink that she had drawn Grievous away from the reactor room, thereby leaving it to the two troopers to plant the explosives. Though he protested to Tano's course of action, Rex adhered to her orders. He and Denal infiltrated the reactor room, fulfilled their objective, and departed to rendezvous with Skywalker and the Twilight in Skytop Station's hangar bay.

When Rex and Denal arrived in the hangar, they joined Skywalker, the Twilight and its clone pilot, and both R3-S6 and R2-D2, the latter of whom had been rescued from Grievous's IG-100 MagnaGuards. Skywalker was shocked to learn that Tano had engaged Grievous in single combat and insisted that Rex and Denal take him to find and assist her. Before they could do so, R3-S6 revealed his true allegiances, sealing the hangar's exits and then transmitting activation codes to a trio of vulture droids hanging from the ceiling. Further Separatist reinforcements arrived in the form of B2 super battle droids, forcing Rex and his comrades to sprint for cover behind some crates on the other side of the hangar. As an intense standoff erupted, Skywalker ordered Rex to trigger the explosives at the reactors, despite the fact that the strike team was still aboard the station. Rex complied and activated the charges, initiating Skytop Station's gravitational descent through the moon's atmosphere.

It was not long before Tano joined the firefight in the hangar, having escaped from Grievous. Rex noticed some fuel cells nearby and informed Skywalker, who used the Force to hurl one of the cells at the opposing droids. As soon as the fuel crate was within range of the droids, Rex landed a well-aimed shot on it, causing an explosion that consumed the enemy infantry. Once R2-D2 had opened the main hangar door from an exterior maintenance platform, Rex boarded the Twilight alongside his comrades to escape from the doomed enemy base. Skywalker completed their successful operation by finally retrieving R2-D2, who had eliminated R3-S6.

The search for Dooku
"Let's try not to blow up the ship before they get off this time."

- Ahsoka Tano, to Rex, during the assault on Dooku's flagship

The Republic eventually launched a manhunt for the Confederacy's leader, Count Dooku, in the hopes of bringing the war to a quicker end. Rex accordingly joined Skywalker, Tano, and Kenobi on the Resolute to spearhead the search. Upon locating Dooku's Munificent-class star frigate in the Outer Rim Territories' Vanqor system, Rex and Tano took over command of the Resolute, while Skywalker and Kenobi infiltrated the frigate to apprehend Dooku. As soon as the Jedi Generals had located Dooku aboard his flagship, Rex and Tano had the Resolute move in and open heavy turbolaser fire on the frigate, summarily crippling the enemy battleship. However, Dooku managed to escape aboard his solar sailer, forcing Skywalker and Kenobi to give pursuit in a stolen Sheathipede-class transport shuttle; Kenobi ordered Rex and Tano to follow in any available craft that they could prepare. Though Skywalker and Kenobi crash-landed on the nearby planet Vanqor alongside Dooku, they were unable to detain the Sith Lord and required an extraction from Vanqor by Tano and a squad of troopers.

Rex was later aboard the Resolute bridge with Skywalker, Tano, and Kenobi when Masters Yoda and Mace Windu of the Jedi High Council made contact to issue new orders to them. A gang of Weequay pirates based on Florrum had taken Dooku hostage, and Skywalker and Kenobi were assigned to confirm that the Sith Lord was in the pirates' custody so that the Republic could ransom him. Yet the pirates, led by Captain Hondo Ohnaka, managed to capture Skywalker and Kenobi after their arrival on Florrum in the hopes of separately ransoming them. Though they escaped, the Jedi failed to prevent Dooku from absconding yet again.

From Quell to Maridun
"You know, I can't figure those villagers not wanting to fight. No pride, I guess."

- Rex, on the Lurmen pacifists of Maridun

When the Resolute received a distress call from Jedi General Aayla Secura, whose fleet had fallen afoul of a Separatist armada in the Outer Rim's Quell system, Rex joined Skywalker, Tano, and their embarked troops to provide aid. By the time they reached Secura's embattled task force in the planet Quell's upper atmosphere, two of her Venator-class Star Destroyers had been disabled by enemy cannonades, with only Secura's flagship maintaining altitude. Entering the ongoing Battle of Quell, Rex and his comrades from the 501st Legion launched from the Resolute in a squadron of gunships, aiming to evacuate all personnel from Secura's cruiser. However, the gunship carrying Rex, Skywalker, and Tano was intercepted mid-flight by one of the Confederacy's airborne B2-RP battle droids, a jetpack-equipped model. While Skywalker commandeered another B2-RP to reach Secura's command ship, Rex and Tano pulled their gunship's clone pilot into the troop bay, as the B2-RP had forced him out of the cockpit. The enemy droid also wrecked the gunship's controls, plunging their transport toward Secura's flagship.

As soon as their gunship lodged itself in the Star Destroyer's hull, Rex, Tano, and their troopers instantly disembarked from their flaming craft and sprinted through the warship's corridors, felling battle droids on their way to rendezvous with Skywalker and Secura. Upon finding Skywalker, Secura, and Clone Commander CC-5052, nicknamed "Bly," in one of the hallways, Rex and Tano headed with their comrades to the ventral hangar, where a Republic frigate that Skywalker had called in was docking to evacuate the troops. Just as Tano extended the gangway to the frigate, the Confederate fleet's escalating bombardment birthed an inferno that raged through the cruiser's hallways. Acting swiftly, Skywalker saved Rex and the others by Force-pushing them into the airlock, then sealed the gateway's blast doors behind them. Yet, Skywalker's efforts to repel the inferno with the Force could not withstand the intensity of the advancing blaze, and he was knocked against the airlock, rendered unconscious. Once Tano and Secura hurriedly pulled the inert Skywalker aboard the frigate, Bly detached their transport from the Star Destroyer and set a course for the Resolute, maneuvering through the ongoing engagement.

Just as the frigate was about to dock with the Resolute, another complication arose. An attack from an incoming vulture droid squadron inadvertently activated the frigate's hyperdrive, sending Rex and his comrades on a blind hyperspace jump before they could stop it. Moreover, their troubles were far from over. Bly found that the navigation computer's incorrectly inputted coordinates had locked their frigate on a collision course with a star in the Outer Rim's Maridun system, and Rex joined him, Tano, and Secura on the bridge to search for a solution. Since the navigation computer was damaged beyond repair, Secura decided that their only course of action was to reset the jump coordinates by restarting the starship's power circuits, even though doing so would deprive Skywalker of his life support in the medical bay. Once they were ready, Secura shut off auxiliary power, forcing their frigate out of hyperspace just in front of the star. However, the craft's forward momentum&mdash;combined with the loss of artificial gravity&mdash;caused Rex to lose his handhold on the back of Tano's chair, and he tumbled backward into Secura, severing her hold on the power switch. Secura promptly used the Force to reactivate the power switch, and Tano was able to safely pilot the frigate around the star, narrowly avoiding it.

Because of the frigate's high velocity, Tano could not prevent their ship from heading into the star's first orbit, the grassland planet Maridun. The frigate lost one of its engines as it plummeted through the planetary atmosphere, and finally landed on the surface in a crash that sent Rex and the others reeling. Kicking open the frigate's starboard escape hatch, Rex ordered everyone out of the transport. He helped one of the wounded troopers to the ground while Tano and Secura carried the still-inert Skywalker to safety, moments before flames consumed the wreckage. Once Rex and Bly used the ship's remains to erect a makeshift shelter for Skywalker, Tano and Secura took Bly and the other surviving soldiers&mdash;Cameron, Flash, and Lucky&mdash;to seek out medical aid for Skywalker from Maridun's inhabitants. Rex, meanwhile, remained at the campsite to protect Skywalker, and Secura had him activate his locator so that they would be able to return to his position. Before Tano left with the others, Rex assured her that he would take care of her Master and also wished her luck.

As the sun set on Maridun's grassy plains, Rex diligently guarded Skywalker into the night, periodically inspecting the campsite's surroundings and passing the time by keeping his DC-15A blaster in working order. When Skywalker awoke and tried to get to his feet, Rex rushed over to check his condition. At that moment, a carnivorous mastiff phalone that had been watching them lunged out of the brush and attacked Rex. The creature pinned him to the ground, trapping his blaster arm underneath one of its claws. A short struggle lasted until Rex managed to fire a blaster shot with his DC-15A, startling the mastiff phalone. It bolted for the grasses, and he aimed a few more blasts at its retreating form. The beast did not stray far, however, and Rex continued to hear multiple mastiff phalones streaking through the adjacent grass.

The next time Skywalker regained consciousness was after daybreak, and Rex urged his Jedi General to conserve what little strength he had left. Yet Skywalker refused to rest, stating that he could hear more mastiff phalones circling the campsite's perimeter. Sure enough, a pair of the hungry creatures leaped into view, and Rex and Skywalker raised their weapons&mdash;DC-15A and lightsaber, respectively&mdash;to defend themselves. Though Rex gunned down one of the mastiff phalones, the other smashed through the makeshift shelter, sending him and Skywalker sprawling to the ground. At that point, Tano and Bly reached the campsite with Wag Too, a healer from the planet's village of Lurmen colonists. On account of his people's practice of pacifism, Too coiled a piece of rope around the creature's legs to subdue it without inflicting harm. Despite an injured arm, Rex contributed as much as his wound would allow, helping Too and Tano tug on the rope to knock over the creature, and Too secured the rope around its legs. With the mastiff phalones defeated, Rex and the others brought Skywalker to the Lurmen village, with Tano and Bly carrying Skywalker on a cobbled-together gurney.

While Skywalker's condition slowly improved thanks to medical treatment from Too, Rex kept watch on the outskirts of the village. It was not long before he spotted an incoming Confederate C-9979 landing craft, and after reporting the craft to Bly, he joined Tano, Secura, and Bly at the seedpod hut where Skywalker was being treated. Since Maridun was a neutral world, Secura decided that the Republic team had to leave the village so that its presence would not endanger the Lurmen. Meanwhile, Tee Watt Kaa, the village elder, surrendered to the Separatists to avoid any conflict. With Rex and Bly carrying Skywalker, they escaped into the tall grass behind the village before the enemy commander, General Lok Durd, could find them. Stopping for a respite in a clearing, Rex stated that he could not understand the Lurmen's penchant for nonviolence, attributing it to a lack of pride. Tano believed it was due to cowardice, but Secura asserted that following one's beliefs required courage. Skywalker focused their attention on the task of escaping off-world, speculating that the Separatists might have a shuttle since they had brought a landing craft to Maridun. Though Rex was eager to plunder from the battle droids, Tano made the alarming discovery that a Separatist probe droid had them under surveillance.

Rex and Bly opened fire on the probe droid, and they pursued the enemy spy with Tano and Secura when it promptly fled into the grass. After a short chase, Secura succeeded in cleaving the droid in half with her lightsaber. To determine the droid's destination, Rex and the others climbed a nearby tree to survey the surrounding area. Their vantage point afforded them a glimpse of the Separatists' base, which had been constructed from a mobile command center. Using a pair of electrobinoculars, Skywalker spotted a Sheathipede-class transport shuttle behind the parked C-9979 landing craft, though Bly noted that the droids' security patrols would make it difficult to reach the shuttle. Presently, Lok Durd held a test run of his Defoliator Deployment Tank, which bore an experimental cannon of his own creation called the Defoliator. At Skywalker's behest, Rex and Bly moved in for a closer look at the enemy weapon, using the plain's tall grasses as cover to approach the base. Durd deployed a pair of B1 battle droids outside the facility to serve as test subjects for the Defoliator, which&mdash;at his command&mdash;fired a missile at the two droids. Catching sight of the incoming missile, Rex and Bly sprinted for safety in the tree. Behind them, the Defoliator capsule birthed a wave of destruction that consumed all organic matter, flora or otherwise, within a radius of several hundred meters. Using their ascension cables, Rex and Bly safely reached the tree, with Bly receiving help from Secura when his cable misfired.

When the inferno dissipated, Durd's pair of battle droid test subjects emerged unharmed, indicating a successful trial for the Defoliator. Durd set off with his droid troops to test his experimental weapon on the Lurmen village, and Skywalker and Secura correctly deduced Durd's destination. Skywalker decided that the Republic team would first eliminate the Separatists' communication system, then steal their shuttle to return to the Lurmen and defend their village from the impending assault. Rex and his comrades waited until after nightfall to raid Durd's minimally guarded base. Once Rex, Skywalker, and Bly had cut down the battle droid guards on the exterior of the facility, Tano and Secura opened the main entrance, allowing Rex and the others to sneak inside and disable the droids manning the communication station. As they made their way to the shuttle, Rex noticed a pair of mobile shield generators, and on Skywalker's orders, he and Bly brought them aboard the starship.

Rex and the others reached the Lurmen village aboard their shuttle just after daybreak. Upon sighting Durd's inbound infantry, Rex estimated that they had at most eight minutes before the droids arrived. Over Taa's vehement protests, the Jedi and clones rushed to prepare a defense of the Lurmen colony, positioning the shield generators in the middle of the village to maximize the shield's range of protection. They also assembled a seedpod barrier in front of the village, working in teams to haul the seedpods into place. Activating his electrobinoculars, Rex reported that Durd's battle group was holding position a considerable distance away; Skywalker theorized that Durd would opt to use his long-range artillery before mounting a charge. Sure enough, Durd had the Defoliator Deployment Tank launch a missile, but Bly activated the shield generators in time to prevent the ensuing inferno from harming the Lurmen colony. In response, Durd sent in his first squad of B1 and B2 battle droids to besiege the village, and Rex and his comrades walked through the shield to repel the droids. While Skywalker, Tano, and Secura waded into the enemy ranks, Rex and Bly supplied long-range fire with their DC-15 blaster rifles. Although they eliminated the first wave of droids, Durd's second wave&mdash;comprised of his second and third squads&mdash;soon followed, bolstered by twice the amount of soldiers and firepower.

On account of their superior numbers, numerous battle droids slipped past the three Jedi, overwhelming Rex and Bly and forcing them to retreat behind the shield. Despite the clone officers' efforts, the enemy droids blasted through the seedpod barrier and obliterated the shield generators, leaving the village vulnerable. Though Tano and Secura joined Rex and Bly in defending the colonists, it was only when Wag Too, his friend Tub, and a number of other like-minded Lurmen sacrificed their pacifistic ways to help defend their home that the battle droids were defeated. Skywalker, meanwhile, crippled the Defoliator Deployment Tank and captured Durd before he could escape, securing a Republic victory. With the battle over, Rex and Bly ushered the detained Durd and his Aqualish aide into the Sheathipede-class shuttle. Too thanked the Jedi for their efforts, as did Taa, who nonetheless questioned the cost of the victory. As Rex and the others prepared to leave Maridun, Admiral Yularen arrived in orbit with a fleet of Star Destroyers, having finally tracked them to the remote world.

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 stand by here. No matter what the chairman thinks, we're not going to war."

- Rex and Anakin Skywalker

When the Republic lost contact with an outpost on the frigid world of Orto Plutonia, Rex accompanied Skywalker, Kenobi, and a platoon of cold assault troops to investigate the lack of response. Joining them were Chairman Chi Cho and Senator Riyo Chuchi from the orbiting moon of Pantora, which claimed the barren ice world as a protectorate due to its lack of sentient life. Upon arrival at Orto Plutonia, Rex, Skywalker, Kenobi, and the Pantoran dignitaries proceeded to the Republic outpost aboard a landing force of LAAT/i gunships. Rex and his platoon sported specialized armor to negate the effects of the extreme cold. Once they had landed at the base, Rex had his men unload their supplies and install an array of sensor beacons to survey the area. When he proceeded into the facility with Kenobi, Cho, and their troops, they found nothing but carnage within. The base's entire crew of clone troopers had been slaughtered, and several of their helmets had been mounted on spears. Yet, there was no evidence of a battle with Separatist droids. Rex soon learned that the platoon's scouts had found a Separatist outpost on the other side of a nearby ice ridge, and he, Skywalker, and Kenobi took a small squad of troopers aboard CK-6 swoop bikes to investigate it.

At the Confederate base, Rex and his comrades were greeted with a familiar scene: numerous cranial units of B1 battle droids, all mounted on spears outside the facility. After helping Skywalker place sensor beacons around the site, Rex joined him and Kenobi inside the complex, which was littered with disabled droids. Kenobi reviewed the droids' communication logs and uncovered a holographic recording of a large life form attacking a battle droid. As to the mystery of the droid's assailant, Rex offered that according to their log, the Separatists had last been scouting the southern canyon. He returned to the Republic outpost with his squad of soldiers while Skywalker and Kenobi pursued the lead. As a heavy storm brewed outside, Skywalker and Kenobi returned with the news that, contrary to the findings of Pantoran scouting parties, Orto Plutonia was an inhabited world. The Jedi had come across a village of Talz, who were responsible for the raids on both bases, since the tribe simply wanted to be left alone. Although Cho was determined to preserve Pantora's claim to Orto Plutonia and ordered Rex to mobilize his soldiers to subdue the Talz, Skywalker and Kenobi intervened. They had promised the Talz that the Republic forces would not offer any retaliation, and had further arranged a meeting with the Talz's chieftain, Thi-Sen, to find a peaceful resolution to the matter. Not to be deterred, Cho demanded that a detachment of troopers escort him and Chuchi to the summit, and Rex and his men complied.

As they began preparations for their departure, Rex noted to Skywalker that the majority of the platoon would have to remain at the outpost, since the ongoing storm had grounded the gunships. Skywalker remarked that despite Cho's intentions, the Jedi did not plan on initiating a war with the Talz. Setting off on CK-6 swoop bikes, Rex and a small squad proceeded with the Jedi and Pantorans to the Separatist outpost, which had been selected as a neutral site for the summit. Once there, Cho commanded Rex to position his men on an adjacent ridge to assault the Talz, but Kenobi countermanded the order, as the Talz had already arrived. At Skywalker's behest, Rex ordered his men to stand down and avoid provoking the Talz. They waited outside while Skywalker, Kenobi, Cho, and Chuchi met with Thi-Sen and his delegates inside the base, with the protocol droid C-3PO translating for both the Talz and the Pantorans. Despite the Jedi and Chuchi's efforts to prevent such an outcome, Cho was adamant about expunging the Talz from Orto Plutonia and declared war on them. While Skywalker, Kenobi, and Chuchi returned to the Republic base to contact the Pantoran Assembly and find a solution to the conflict, Rex and his men took swoop bikes and BARC speeders to accompany and protect Cho.

As they approached a canyon, Cho spotted a trio of narglatch-mounted Talz warriors and ordered Rex's troops to open fire once they were within range. Though Rex reminded Cho that he and his soldiers were only there to provide protection, they realized it was an ambush when more Talz emerged from beneath the ice. In the subsequent assault, a Talz and his narglatch mount forced Rex out of his swoop bike. He summarily gunned down his assailant and kicked over his bike for cover, having his men do the same to form a defensive perimeter around Cho and his Pantoran bodyguards. However, the clone troopers endured a number of casualties, and Rex thus ordered a withdrawal, directing his first squad to cover their retreat. Cho angrily protested to such a course of action, but he was interrupted when one of the Talz's spears impaled him from behind. As another Talz moved in to finish off Cho, Rex barreled over the warrior with a spare BARC speeder and killed two more Talz before they could reach Cho. He heaved the injured chairman onto the BARC speeder and joined the rest of his men in retreating.

Nevertheless, Thi-Sen and his men gave pursuit, catching up with the clone contingent and clobbering several troopers right off their speeders. Rex and his men soon reached an ice bridge that could not withstand their weight; it collapsed, claiming the lives of two more soldiers, before he and his comrades ground to a halt at the edge of the cliff. Trapped between the ravine and Thi-Sen's advancing warriors, Rex signaled his troops to hold the line. He and his men used their speeder bikes as cover to concentrate blasterfire at the charging Talz, who flung spears at them in retaliation. Both sides took on even more losses, bringing the clones' body count to eleven, before Rex and his men heard the sound of gunship engines: Reinforcements had arrived. Skywalker, Kenobi, and Chuchi touched down with a squadron of LAAT/i gunships in front of the gorge, ferrying more troops from the clone platoon. As a result, Thi-Sen and his tribe halted their charge, and Rex and his soldiers took a moment to tend to their wounded. While the dying Cho succumbed to his injuries, Chuchi&mdash;having received the necessary authorization from the Pantoran Assembly&mdash;met with Thi-Sen and negotiated an end to the bloodshed, peacefully granting control of Orto Plutonia to the Talz in recognition of their sovereignty. With the hostilities abated, Rex and his soldiers departed from the region with Skywalker, Kenobi, and Chuchi aboard their gunships.

Virus outbreak 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

Following Senator Padmé Amidala's discovery that the Separatist-allied Doctor Nuvo Vindi was working in a secret research laboratory beneath Naboo's eastern swamps to weaponize the fatal Blue Shadow Virus, Rex accompanied Skywalker, Tano, Kenobi, and a strike team of clone troopers to shut down Vindi's operation. Aboard an LAAT/i gunship, Rex and his soldiers rendezvoused with Tano at the underground laboratory's south entrance, which she breached using explosives; he and his men then rappelled into the ruptured tunnel and launched an offensive on Vindi's battle droid defenses. Thanks to their distraction, other clone units led by Skywalker and Kenobi were able to enter the compound at other locations without resistance. Rex and Tano pressed forward against the enemy droids, but the appearance of two shielded droidekas impeded their charge and forced them to fall back. Several of Rex's troopers fell to the droidekas' laser fire until Kenobi and his team of bomb squad troopers arrived, collapsing part of the tunnel and crushing the droids underneath the rubble. Rex, Tano, and their two remaining soldiers proceeded with Kenobi and the bomb squad to a nearby junction, where they split up upon encountering more battle droids.

While Rex, Tano, and their men drew the attention of Vindi's droid security forces, Kenobi took the bomb squad to dismantle the facility's supply of viral bombs, which Vindi had designed to be vessels for the virus. The bombs would spread the pathogen to key Republic star systems, thus generating a galaxy-wide plague. After disabling their droid opponents, Rex and Tano continued through the compound and ran into Skywalker's team at another junction. With them were Amidala and Representative Jar Jar Binks, whom Skywalker had rescued from being held captive by Vindi. Rex and his comrades learned from Skywalker that Vindi, still at large, had activated his entire stockpile of viral bombs, one of which was missing. Amidala relayed that earlier, she had seen Vindi hand one of the bombs to his LEP servant droid, leading Rex and Tano to depart with their men in search of the missing bomb. Upon receiving word from Amidala that she and Binks had found the stray bomb in the arboretum, Rex and Tano rushed there with the bomb squad, which had finished defusing the rest of the bombs. One of the ordnance specialists deactivated the explosive just in time, much to the relief of Rex and the others. Skywalker and Kenobi, meanwhile, apprehended Vindi, averting the threat of an outbreak.

While Skywalker and Kenobi escorted Vindi to Naboo's capital, Theed, to await trial, Rex and Tano assisted Amidala in the cleanup efforts at the laboratory. Unbeknownst to them, Vindi's assistant droid had purloined the virus vial from the last bomb before escaping, and manually released the Blue Shadow Virus into the compound using a spare explosive at the bomb room. Upon hearing the alarm for the virus leak, Rex, Tano, and their soldiers made for the nearest safe room. When the safe room's blast door began to seal itself shut, Tano used the Force to hold open the door so that Rex and the other troops could climb through, and they propped the door open long enough for her to join them inside. Yet, one of the troopers discovered via the room's scanning equipment that a small strain of the airborne pathogen had slipped inside before the door closed: Rex and his comrades were infected. Despite their quandary, Rex resolved to eliminate the remainder of the facility's battle droids, even if such an act would be his last. Amidala and Binks, clad in hazmat suits, entered the safe room and met with Rex and Tano, distraught that their colleagues were infected. Still, all of them were intent on completing their objective, for if a single battle droid broke out of the bunker, the rest of Naboo would be consequently infected.

After offering a DC-15A blaster to Amidala, Rex joined Tano and another trooper in sweeping the north corridor for battle droids while Amidala, Binks, and the other troops took the south passage. Both squads met at the south exit, where Rex and Amidala gunned down the last battle droid that was attempting to cut through the exit hatch. As they scoured the rest of the bunker, Rex and the others came across a pair of droidekas, which they swiftly eliminated. Yet, their success was not without a cost: Amidala's hazmat suit was compromised in the scuffle, exposing her to the virus. Nonetheless, Rex and his comrades continued through the bunker until they had eradicated the last of the battle droids, ensuring that Naboo was safe from further contamination. As the plague took its toll, Rex aided Amidala in tending to the other afflicted troopers, doing what they could to alleviate their suffering even as the men succumbed to the virus. Though Amidala lamented the soldiers' wasted lives, Rex replied that it was what they had been born to do. Overcome by the effects of the virus, Tano fainted, and Rex caught her as she collapsed.

Before long, Skywalker and Kenobi returned from the distant planet Iego, where they had collected a sample of reeksa root as an antidote for the plague. Thanks to their efforts, Rex and the other afflicted were administered the antidote, which neutralized the virus. Slated to make a full recovery, Rex and his comrades were placed on mobile stretchers and were brought to the compound's landing pad, where 2-1B medical droids ushered them onto waiting LAAT/i gunships. Before leaving with the others for further treatment, Rex made it clear to Kenobi that he had no desire to help train Binks, whom Amidala had recommended for blaster training. Rex later healed and returned to fighting shape.

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

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

In response to the Confederacy's invasion and subjugation of the Twi'lek homeworld of Ryloth, Rex was deployed to the occupied world aboard a Republic fleet under the command of Skywalker, Tano, and Admiral Yularen. He and his comrades were tasked with eliminating the Separatist blockade of Ryloth to secure safe passage for Kenobi and Mace Windu's main invasion force from the Grand Army. Skywalker and Tano's first assault on the blockade failed, forcing their battle group to withdraw from the Ryloth system aboard the Star Destroyers Resolute and Defender, while enemy fire claimed their third cruiser, the Redeemer. Yularen was severely wounded, and Tano, who led Blue Squadron in her first command position, lost most of her men. As the Resolute and the Defender reached their staging area, Rex sought out Skywalker, who was in the hangar trying to console a dejected Tano, to inform him that Windu had requested a status update from them. At Skywalker's behest, Rex compiled a damage report to assess their losses and then joined Skywalker on the Resolute bridge to holographically apprise Kenobi and Windu of their progress. Since it was imperative that they liberate Ryloth from the Separatist-allied Techno Union, Windu granted Skywalker's fleet a single planetary rotation to breach the blockade. At his general's request, Rex went to locate Tano and found her in the medical bay visiting a comatose Yularen; she left with Rex upon hearing that her Master was looking for her.

Rex soon received word of a complication aboard the Defender and relayed the news to Skywalker via comlink. Due to the Defender damages, Skywalker chalked out a plan to personally pilot the cruiser into a collision with the command ship of the Separatist blockade, thereby leaving the enemy armada in disarray without its captain, Mar Tuuk. To that end, Skywalker ordered the Defender evacuated, and Rex joined him in the Resolute hangar to help supervise the processing of the incoming matériel as LAAT/i gunships ferried it from the Defender. When Tano arrived, Rex stepped in to oversee the cargo sorting while Skywalker explained his plan to his Padawan, who was to assume command of the Resolute in the interim to eradicate the remainder of the blockade. Though Tano felt unprepared for so much responsibility, Skywalker gathered Rex and their men to inform them that Tano would brief them on the full attack plan. Before Skywalker departed for the Defender, Rex asked him to leave some battle droids for him and the troopers, though Skywalker made no promises.

With Yularen still out of action, Rex joined Tano on the Resolute bridge, where she apprised him and the ship's navigation officer of Skywalker's plan. Rex, wary of their unfavorable odds, voiced hesitancy with the strategy's chance for success, as did the navigation officer. Furthermore, there was still the task of annihilating the Separatist blockade, complicated by the fact that once Skywalker eradicated Tuuk's command ship, the Resolute would be exposed to attack from the blockade's six remaining Munificent-class star frigates. To compensate for that vulnerability, Tano proposed that they angle the Resolute hull toward the Confederate frigates, a move that she believed would protect the Resolute bridge and hangar from the Separatists' superior firepower. The maneuver would also draw in the frigates, making it possible for a starfighter strike to outflank them. Both Rex and the navigation officer were apprehensive about employing such a risky maneuver, but a convalescent Yularen arrived on the bridge and supported Tano's proposal, stating that the circumstances warranted such a drastic strategy. Upon their return to the Ryloth system, Tano delegated command of the Resolute to Rex and Yularen while she left to command the starfighter assault.

Once Skywalker had rammed the Defender into Tuuk's Droid Control Ship, Rex and Yularen moved the Resolute into position, ready to execute Tano's plan. Yet, the Confederate frigates did not immediately converge on the Star Destroyer, and Rex and Yularen concluded that they had to retreat if the Separatists did not attack. Tano advised them to be patient, believing that the frigates' droid commanders would take the bait. Sure enough, the frigates moved in a few moments later to pummel the Resolute with a torrent of cannonades, and Tano responded by leading several squadrons of V-19 Torrent starfighters and Y-wing starfighters into battle against them. Trapped, the enemy frigates were unable to escape from the agile bombers, and they were obliterated. Shortly thereafter, Kenobi and Windu arrived with the invasion force aboard a trio of Acclamator-class assault ships. After referring the Jedi Masters to Tano, Rex dispatched a shuttle to retrieve Skywalker's escape pod, completing their successful strike. With Tuuk's blockade defeated, Kenobi and Windu were able to deploy their forces on the surface and aided the local Twi'lek freedom fighters in recapturing Ryloth's capital, Lessu. Windu also arrested Techno Union Foreman Wat Tambor, who had overseen the Confederate invasion.

Retreats and losses
"Come on, grunts! We are leaving!"

- Rex barks out an order to evacuate from the Felucia battlefield

Rex and Cody joined a ground assault force that Skywalker, Tano, and Kenobi took to defend Felucia, a contested world in the Outer Rim, from a Confederate invasion. Their contingent of troops became based out of a clearing amidst Felucia's dense foliage, from where they executed strikes on the outlying droid infantry. Yet, the battle droids' superior numbers overwhelmed the Republic troops, and they called in an extraction. Once Plo Koon and an LAAT/i gunship squadron had breached the Separatists' orbital defenses and landed in the clearing, Rex and Cody herded their men onto the gunships, backing into one of the craft while returning blasterfire at the surrounding battle droids. As soon as Skywalker and Kenobi had boarded their gunship, they went to retrieve Tano, who was overseeing a jungle patrol six kilometers to the east. Though Tano refused to retreat, Skywalker had their gunships land between her patrol and the inbound droids, forcing her squad to abandon their assault and join Rex and the others aboard their craft. They lifted off just as droid reinforcements liquidated the ground vehicles that Tano had left behind.

Though the Republic was unable to maintain its foothold on Felucia, it was not long before Rex returned to the galactic theater of war. He was part of a strike team under the command of Skywalker and Tano that was assigned to retrieve a holocron that the bounty hunter Cad Bane had pilfered from the Jedi Temple's Archives. Rex and his comrades traveled aboard the Resolute to the Devaron system, the last known location of Bane's next target: Jedi Master Bolla Ropal, the guardian of the Jedi Order's Kyber memory crystal. By the time the Resolute arrived over Devaron, Bane had already captured Ropal in order to acquire the Kyber memory crystal, which served as a data repository of all known Force-sensitive infants throughout the galaxy. As Bane rendezvoused with a Trade Federation fleet of Munificent-class star frigates, the Resolute moved in to prevent Bane from escaping, blasting his frigates to smithereens one by one. Skywalker had the Resolute target Bane's command ship, trapping it in-system by disabling its hyperdrive. Rex assembled their embarked forces in the Resolute hangar and mobilized three brigades of troopers for the impending mission. When he learned from Skywalker that they would be boarding Bane's frigate to rescue Ropal and the stolen holocron, he expressed hesitancy, since they did not have access to any suitable boarding craft aside from a couple of starfighters and the Twilight.

Consequently, Skywalker opted to use three of the Resolute AT-TE walkers to transport the boarding party to Bane's frigate. Though Admiral Yularen was appalled at the idea, Rex and Tano commended Skywalker on his trademark improvisation, since the walkers' pressurization and magnetic feet made them suitable as transports. Over Yularen's objections, Rex marshaled their troops, assigning Execute Battalion to Walker ATAT300 and Carnivore Battalion to Walker 773. The Resolute maneuvered into position over Bane's frigate to deposit Rex and the boarding party aboard the three walkers onto the battleship's hull. While the walkers' gunnery crews provided covering fire, Rex and the others blasted their way through the frigate's deployed defenses of B1 battle droids and vulture droid starfighters. Once the droids had been repelled, R2-D2 opened an airlock on the frigate's hull, allowing Rex and his comrades to enter the vessel. They immediately stormed the bridge, eliminating the ship's battle droid crew. Yet, Bane was nowhere to be found. Scouring the frigate's computer, R2-D2 uncovered a holographic record of a conversation between Bane and Trade Federation Viceroy Nute Gunray, which revealed that Bane had acquired both the holocron and the memory crystal, having purloined the latter from Ropal.

On Skywalker's orders, Rex sent a squad of troopers to lock down the hangar and disable the frigate's escape pods to prevent any enemy forces from escaping. However, he refrained from joining the squad when a series of explosions shook the ship as a result of Bane's remote activation of the self-destruct sequence. Instead, he accompanied Skywalker, Tano, and the rest of the boarding party to search the ship for Ropal. When Tano found Ropal dead in one the frigate's holding cells located below decks, Skywalker ordered Rex to have some of his men transfer Ropal's corpse to the Resolute. The deck lights were suddenly extinguished, and R2-D2 used his headlamp to lead Rex and the others through the dark hallways in search of Bane. Upon blindly colliding with a protrusive pipe, Rex told his men to switch their helmet visors to night vision, doing so himself by pulling down his helmet scope. They soon caught sight of a fleeing Bane and pursued him to the darkened gunnery deck, where Bane, having lured them there, switched on the lights to reveal a contingent of battle-ready droids. An intense standoff ensued, with Rex and his comrades concentrating their blasterfire on the B1 and B2 battle droids amidst the artillery stations.

Bane soon decided to intensify the firefight by deactivating the frigate's artificial gravity, causing Rex and the others to float off the deck in zero gravity. Undeterred, he and his troopers used their magnetic gripsoles to latch onto various footholds before resuming their efforts against the droids, with the captain securing himself to one of the artillery guns. When one of his blaster cannon–wielding soldiers gunned down a battle droid and inadvertently dislodged an ammunition canister from a storage rack, Rex warned his men to check their aim, since even a single detonated shell would result in an unavoidable explosion. They continued to gun down the droid infantry even after R2-D2 re-enabled the gravity generators, which momentarily sent Rex and the others tumbling back down to the floor. When Bane lured Tano into a dead-end hallway and sealed the blast doors behind her, Skywalker rushed over and began to slice through the blast doors with his lightsaber to rescue his trapped Padawan. However, the gunfight thereafter came to a swift end when a battle droid tripped and misfired at an ammunition canister.

The blast from the exploding shell caused debris to separate Rex and his men from Skywalker. Unable to shift the mounds of rubble, Rex called out to his Jedi General and finally received a reply, confirming he was alive. While Skywalker went to aid Tano in confronting Bane, Rex headed for the hangar with R2-D2 and his soldiers, aiming to secure a transport that they could use to escape from the frigate. They did not have much time, as a growing fire on the gunnery deck threatened to ignite the entire supply of ammunition. At the hangar, Rex and his men found that the squad he had sent earlier was in mid-battle with B1 and DSD1 battle droids that were guarding a vacant Sheathipede-class shuttle. Using some nearby crates as cover, he and his men joined the fight for the shuttle, opening fire on the advancing droids. Rex soon received word from Yularen that the frigate's main reactor was exposed and would implode at any moment. Splitting his forces, Rex sent Denal and another trooper to assist Skywalker and Tano in their pursuit of Bane, while he continued to spearhead his squad's efforts to capture the shuttle.

Presently, Rex and his troops triumphed over the battle droids and sprinted onto the appropriated shuttle, which they defended from additional droid forces. Rex finally received word from Skywalker, who had rescued Tano, and advised his Jedi General that they had to leave as soon as possible on account of the reactor's impending implosion. He and his soldiers held out long enough for Skywalker and Tano to reach the hangar and join them and R2-D2 aboard the shuttle. Before jettisoning from the frigate, Rex and the others witnessed Denal gun down Bane on the hangar's upper deck and picked up Denal to escape with them. However, the armor-clad trooper was in fact Bane, who had murdered Denal and had stolen his armor. When Skywalker questioned him, "Denal" alleged that he had been unable to retrieve the holocron from Bane. The shuttle escaped from the frigate mere seconds before the supply of ammunition detonated, tearing apart the vessel.

Returning to the Resolute, the Jedi and clones disembarked from the shuttle, though Rex and another soldier stayed aboard after spotting several drops of green blood on the ship's deck. Rex called over Skywalker to show him their discovery, remarking that the alien blood was certainly not from any of the clones. Skywalker and Tano simultaneously realized Bane's exploits, and the bounty hunter promptly bowled over Tano and bolted for the hangar's nearby stock of starfighters. Bane commandeered a V-19 Torrent starfighter, and before Skywalker could apprehend him, he forced Skywalker off his stolen craft and piloted it out of the Resolute hangar. Rex, a recovered Tano, and their men could only watch as Bane made his getaway. Despite being alerted by Skywalker, Yularen's bridge crew was unable to lock down the hyperspace transport rings in time, and Bane absconded with one to escape to hyperspace. Although Bane remained at large, the Jedi Order later reclaimed the stolen holocron from his hideout in the Outer Rim.

The Zillo Beast of Malastare
"Stay with General Kenobi. I'm on my way.''" "''Better hurry, sir. You're missing all the fun."

- Anakin Skywalker and Rex, responding to the Zillo Beast's escape on Coruscant

Rex was part of a Grand Army detachment that Skywalker and Mace Windu brought to the Mid Rim world of Malastare, as the Republic's war machine coveted the planet's vast fuel reserves. In what became known as one of the longest and fiercest campaigns of the war, a thousands-strong army of Separatist battle droids made great strides in its conquest of Malastare, jeopardizing the Republic's odds of success. Supreme Chancellor Sheev Palpatine responded by authorizing the Republic's use of the electro-proton bomb, a creation of one of the Republic's leading scientists, Doctor Sionver Boll. While Skywalker and Windu joined Boll and Doge Nakha Urus, the leader of Malastare's native population of Dugs, at the latter's Imperial palace, Rex was tasked with shoring up the palace's fortifications until the detonation of the bomb. He proceeded to the palace's forward defensive lines to oversee the ground assault on the incoming Separatist army. There, he monitored the droid infantry's approach with a set of electrobinoculars, recognizing the droids' enormous tactical advantage.

When the battle droids initiated their offensive, Rex held the line with his men, working in tandem with squads of insectomorph-mounted Dug soldiers to repulse the droid infantry. However, Rex lost a myriad of his comrades to the droids' thick ranks, particularly when a unit of DSD1 dwarf spider droids advanced on their position. Once all was ready, a Republic starfighter squadron deposited the electro-proton bomb in the middle of the droid army, producing an enormous explosion that transformed into an electromagnetic pulse. The energy field disabled all of the battle droids and disrupted the clone troopers' helmet systems and ground vehicles for a brief span of time. The bomb also destabilized its area of impact, and Rex and his troops turned and sprinted away as the tremors caused a massive sinkhole in the ground. Rex nearly fell into the expanding sinkhole when he was caught on an unstable plateau, but he managed to jump to higher ground, where one of his soldiers pulled him to safety. While clone rescue teams were dispatched to retrieve the Republic personnel trapped in the crater, Rex joined Skywalker, Windu, Boll, and Urus at the Imperial palace, where they re-established holographic communications with Palpatine to deliver a status report.

After Windu and Urus conferred with Palpatine on the state of the Republic's impending fuel treaty with the Dugs' council, Rex learned that their frontline forces had lost contact with the rescue team in the crater, and relayed the news to his Jedi Generals. As a result, Skywalker and Windu departed to, respectively, attend to the Dug leaders and aid the rescue team with a clone squad led by Clone Commander CT-411, nicknamed "Ponds." Before long, both Jedi found that the electro-proton bomb had awakened a colossal Zillo Beast that had been hibernating in the crater. The creature's emergence caused a rift between the Jedi and their Dug allies. Whereas Urus demanded that the Jedi help the Dugs kill the beast on account of an ages-old enmity with its kind, Windu refused to do so, since it was an innocent life form and quite possibly the last of its near-extinct species. As night fell, Rex met with Skywalker, Windu, and Boll at the Imperial palace to contact Palpatine and devise a solution to their dilemma. Skywalker proposed that they use the Republic's stun tanks to knock out the creature and transport it safely off-world, thereby concealing its survival from the Dugs in order to appease them. At Boll's recommendation that the Zillo Beast's highly durable scales merited further study, Palpatine approved the strategy.

Rex served with Skywalker and Windu's assault force to subdue the Zillo Beast, and they succeeded in rendering it unconscious with their stun tanks. Afterward, Rex returned with Skywalker and Windu to Urus's palace, where Urus and the other Dug leaders finally ratified the fuel treaty. With the conclusion of the Battle of Malastare, Rex and the others prepared to withdraw from Malastare. Although Windu had planned to deliver the Zillo Beast into solitude on an uninhabited Outer Rim world, Palpatine ordered that they bring it to the Republic capital of Coruscant for study before its release into the wild. Rex thus returned to Coruscant with Skywalker, Windu, and Boll aboard an Acclamator-class transport, with the dormant Zillo Beast in tow.

On Coruscant, the Zillo Beast was transferred to the Republic Science and Technical Center, where Boll conducted research on the creature's scales in the hopes of synthesizing them into a new, impenetrable clone trooper armor. That evening, in spite of extensive containment measures, the Zillo Beast broke out of the Science and Technical Center and began a rampage across the Coruscant cityscape. As the creature headed for the Senate Office Building, Rex joined a strike team led by Kenobi and Windu that set out to contain the beast. En route to a staging area aboard the team's LAAT/i gunships, Rex holographcially contacted Skywalker through R2-D2, both of whom were meeting with Palpatine and Padmé Amidala in the Chancellor's office at the Office Building, and confirmed that he was to serve with Kenobi for the time being. Yet when Rex, Kenobi, and Windu reached the Senate Plaza with their detachment of troops and stun tanks, they found that the Zillo Beast had grabbed hold of the executive shuttle that Skywalker, Palpatine, and Amidala were using to escape from the Office Building with R2-D2 and C-3PO.

As Yoda and Aayla Secura arrived to participate in the containment efforts, Rex monitored the Zillo Beast and its captives through a pair of macrobinoculars and noticed that Skywalker was cutting the executive shuttle in half with his lightsaber. Kenobi and Windu deduced that Skywalker meant to free himself and the other passengers by slicing the ship in half. While Yoda and Secura ran interference to distract the Zillo Beast, Skywalker finished severing the shuttle in two, liberating himself and the others from the creature's grasp. Kenobi and Windu swiftly reached out with the Force to stabilize the section of the shuttle carrying Palpatine and a Senate Commando, preventing them from falling off the dome of the Office Building. As the tanks trained stun pulses on the Zillo Beast, the LAAT/i gunships launched with Rex, Kenobi, Windu, and their men aboard and also opened fire, though neither approach had much of an effect on the rampant beast. Left with no other options, Palpatine ordered the gunships to release a cache of toxic gas bombs that Boll had developed to kill the creature. Though the gas bombs proved effective, thus saving the Coruscanti populace from further harm, the victory came at the cost of the Zillo Beast's life.

The following morning, the slain Zillo Beast was hauled back to the Science and Technical Center. Rex and his comrades met with Palpatine in the Senate Plaza to debrief the incident, mourning the loss of the creature. While Rex and the others departed from the Senate Plaza aboard the gunships, Palpatine secretly issued Boll orders to clone the Zillo Beast.

Second Battle of Geonosis
"Rex! Tell the men to fall back!''" "But, 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, during the assault on Poggle the Lesser's main droid foundry

In the wake of Padmé Amidala's discovery that Geonosian Archduke Poggle the Lesser was in the process of building a new droid factory on Geonosis to bolster the ranks of the Separatist Droid Army, the Republic further learned that the Confederate-allied Geonosians had regained control of their homeworld since the outset of the war. Rex was part of a massive Grand Army contingent that was dispatched to retake Geonosis and shut down the series of droid factories that the Geonosians had established. Once the Republic Navy's invasion fleet had arrived in orbit of Geonosis, Rex, Cody, and Clone Commander CC-1993, nicknamed "Jet," met with their commanding officers&mdash;Jedi Generals Skywalker, Kenobi, and Ki-Adi-Mundi, as well as Commander Tano&mdash;in the lead cruiser's war room to review their attack plan. Because Poggle's main factory was ray shielded, the Republic forces intended to mount a three-pronged assault on the Geonosian defenses: Mundi and Jet from the north, Kenobi and Cody through the middle, and Rex, Skywalker, and Tano from the south. Once they had established a defensive perimeter just short of the ray shield, all three teams would then converge on their primary target: the shield generator. With the strategy in place, Rex left with Skywalker and Tano to begin preparations for their departure, as did the other Jedi and clone officers.

Once the Republic fleet moved into position, the invasion began. Rex and his team lifted off aboard a squadron of LAAT/i gunships and LAAT carriers, the latter ferrying AT-TE walkers; their deployment followed and preceded those of Kenobi's and Mundi's forces, respectively. They encountered heavy resistance from the Geonosians, who employed Nantex-class starfighters in the air and LR1K sonic cannons on the ground to hamper the inbound Jedi and clones. The gunship ferrying Rex, Skywalker, and Tano was one of the first to be shot down by enemy fire, and they careened into the planetary desert near an encampment of Geonosian warriors. Skywalker heaved away the remains of their gunship, and Rex and his comrades clambered out of the wreckage, scrambling for cover from the Geonosians' repeating blaster cannons. Since they had lost their AT-TEs in the air, Rex delivered a status report to Jet, whose strike team had similarly crash-landed, and then tried to hail Kenobi for reinforcements. However, he learned from Cody, whose contingent was so far the only one that had reached the landing site, that Kenobi's gunship was among the downed craft. He consequently ducked behind some rock cover with Skywalker to inform him and Tano of Kenobi's inability to provide support.

Making do with their available resources, Rex readied his men for a charge and followed Skywalker and Tano in barreling toward the Geonosian encampment. They prevailed over the enemy gunners and resumed their trek to the rendezvous point. However, their path led them through a canyon that the Separatists had barricaded with a wall riddled with gun emplacements and battle droid defenses. When the droids opened fire, Rex and his comrades rushed for cover behind some nearby outcrops, but two troopers were slain before they could reach safety. During the intense firefight that erupted, Skywalker and Tano decided to collapse the barricade with a supply of thermal detonators. While the Jedi ascended the cliff with explosive-laden backpacks, Rex and his men provided covering fire for them. After unleashing a spate of blasterfire that eliminated one of the wall-mounted cannons, Rex noticed that Skywalker and Tano had reached the top of the wall but were in need of assistance, as they had encountered a multitude of battle droids. Ordering his soldiers to concentrate their firepower on the droids at the top of the barricade, Rex headed off to climb the cliff himself. He arrived atop the wall just as Skywalker and Tano were in mid-fight with their final opponents: a pair of shielded droidekas.

Sneaked up behind the droideka that was attacking Tano, Rex walked through its personal deflector shield and fired a headshot at point-blank range, disabling the droid. The distraction also enabled Skywalker to swiftly eliminate the other droideka. After tossing their load of explosives into a nearby hatch, Skywalker and Tano called upon the Force to levitate Rex into the air. All three of them jumped off the barricade seconds before the explosives tore through it. The Jedi used the Force to safely land on the ground, employing the same technique to cushion Rex's fall just as the barricade came crashing down around them. Mobilizing their men, they proceeded onward to the rendezvous point. As they neared a clifftop cave, Tano noticed a swarm of flaming Geonosians falling out of the cavern, and Skywalker recognized Mundi, Jet, and their soldiers combing through the surviving Geonosians atop the cliff. Rex and his comrades thus joined forces with Mundi's contingent for the final push toward the landing site, where Kenobi, Cody, and their troops were in desperate need of support against the Geonosians.

Shortly after Admiral Yularen sent in a squadron of Y-wing bombers to obliterate the approaching Geonosians, Rex and the others arrived at the landing zone to reinforce Kenobi's beleaguered forces. After a short briefing, Rex and his fellow officers set out to fulfill their final objective: destroying Poggle's shield generator. Once Skywalker and Tano had led a small squad into the ray shield and disabled the Geonosians' long-range artillery with EMP grenades, Cody moved in with the AT-TE walkers and blasted through the shield generator and its artillery stations. With the shield down, Rex, Mundi, and Jet brought in the rest of the troops aboard the gunships, forcing the outnumbered Geonosians to surrender. While Kenobi and Mundi returned to the fleet to recuperate from the wounds they had sustained, the task of eliminating Poggle's main droid foundry fell to Rex, Skywalker, and Tano.

By the time Rex and the others arrived at the primary droid factory, Poggle was holed up inside the installation, which was isolated by an immense canyon. Rex and his comrades established a staging area near the only bridge that spanned the chasm. When Jedi General Luminara Unduli and her Padawan, Barriss Offee, landed with troop reinforcements, Rex greeted them as they disembarked from their gunship and directed them to Skywalker and Tano. Together, the four Jedi devised a plan to destroy Poggle's fortress. While Tano and Offee infiltrated the facility via the network of catacombs beneath it and planted explosives at the factory's reactor, Skywalker and Unduli would spearhead an assault on the fortress to occupy the attention of Poggle's droid garrisons. Though a frontal offensive would be risky since the canyon bridge afforded scant cover, Skywalker and Unduli hoped to consequently entice Poggle into engaging them in open warfare. Before departing on their mission, Tano and Offee synchronized their chronometers with those of their Masters so that the latter could monitor their progress.

Rex joined Unduli's clone commander, CC-1004, and their Jedi Generals to lead their men's parade-style march on the foundry. As they neared the bridge, they met Poggle's deployed infantry of B1 and B2 battle droids and began their assault. The surrounding area provided little cover, so Rex and CC-1004, nicknamed "Gree," worked quickly with their soldiers to cut through the droid ranks. When a squad of droidekas rolled onto the battlefield and attacked Skywalker and Unduli, Rex sent forward a trooper armed with a RPS-6 rocket launcher to aid the Jedi. The trooper demolished the four droidekas, and the Republic's AT-TE walkers further hindered the droid infantry. With his forces outgunned, Poggle deployed twenty prototype super tanks, which filed out of the foundry to confront the Jedi and clones. At Skywalker's behest, Rex had the detachment's AV-7 Anti-vehicle Cannons target the inbound tanks, giving the order to fire once the tanks had reached the far side of the bridge. Yet, the heavy cannons failed to pierce the ray shields of the super tanks, which responded by launching a volley of missiles. The Republic detachment lost its AV-7 Anti-vehicle Cannons, AT-TE walkers, and many troops on account of the enemy barrages.

As Rex took cover from the super tanks' bombardment with his fellow officers, Skywalker ordered him to retreat with his men. Though Rex objected to such a tactic, Skywalker revealed his intention to draw the super tanks onto the bridge, which he and Unduli would then rupture using explosives. Rex thus retreated with Gree and their soldiers, luring the tanks onto the bridge and allowing their Jedi Generals to affix thermal detonators at key points on the underside of the pass. Once he and Unduli had reached the other side, Skywalker activated the explosives, plunging the tanks into the abyss below. Yet, there was still the matter of the Padawans, who had made it to the foundry's reactor and planted their explosives there, but had not been heard from since. Via comlink, Rex reported to Skywalker that his troops had not spotted Tano or Offee on their side of the canyon, but he urged Skywalker to board one of the evacuation ships. However, Skywalker refused to do so without Tano. Inside the factory, meanwhile, a squad of Geonosian warriors had pilfered Tano and Offee's supply of thermal detonators, forcing them to use a hijacked super tank to annihilate the reactor. As a result, Poggle's foundry erupted in a spectacular chain of explosions, generating a dust cloud that enveloped the blast site.

Once the sand had settled, Rex and Gree boarded an LAAT/i gunship and found Skywalker and Unduli amidst the debris field. With Tano and Offee buried somewhere underneath the rubble, Rex mobilized their battle group's LAAT carriers to haul away the heavy wreckage. He personally partook in the cleanup efforts, working with his men to move some of the smaller mounds. Eventually, it was Tano who signaled her comrades to her and Offee's location, using a power cell to boost her comlink's reception. Skywalker detected the resulting pulse on Tano's comlink channel, and Rex and Unduli quickly followed him to the designated area. Though Rex offered to have the LAAT carriers shift the heavy debris, Skywalker declined; he and Unduli instead drew upon the Force to move the rubble themselves. From the shattered hull of their super tank emerged Tano and Offee, grimy and coughing but alive. Rex waved over some of his men to help Tano and Offee climb up to ground level, and the Padawans had a jubilant reunion with their Masters. On account of their efforts, Tano and Offee were allocated a respite from the battle, and Rex saw them off at one of the Republic's staging areas. Before leaving aboard a medical convoy of gunships, Tano and Offee promised to return soon to assist in the cleanup of Geonosis.

Although Republic forces eliminated other Geonosian droid foundries, Poggle remained at large, having escaped the destruction of his primary factory. Consequently, it was not until Skywalker, Kenobi, and Unduli apprehended Poggle that they secured a Republic victory in the Second Battle of Geonosis, as it came to be known. During their arrest of Poggle, the Jedi also defeated the Geonosians' true leader, Queen Karina the Great, in her lair beneath the Progate Temple, quashing the Geonosian resistance and recapturing Geonosis as a whole. While Tano and Offee took the Pelta-class frigate TB-73 on a supply run to a medical station near Ord Cestus, Rex accompanied Skywalker, Kenobi, Mundi, and Unduli on a Venator-class Star Destroyer to escort Poggle to Coruscant, where the Geonosian archduke was to undergo trial.

As they journeyed through hyperspace, Rex joined the four Jedi Generals on the cruiser's bridge to discuss a complication: TB-73 had missed a scheduled check-in, and the crew was not replying to Unduli's hails. Whereas Skywalker assumed that Tano and Offee were in trouble, Kenobi believed it was not worth worrying over. Hence, Mundi refocused their attention on Poggle, who was resisting their questioning and was refusing to divulge any Confederate military intelligence. Before leaving with the other Jedi to resume Poggle's interrogation, Skywalker privately told Rex to remain on the lookout for any contact from Tano, which he agreed to do. Rex soon contacted TB-73 himself, and Tano answered his transmission, expressing her relief to hear from him. Once Rex patched Skywalker through, Tano reported that her frigate was infested with a batch of Geonosian brain worms, which were capable of mind control and had already infected most of TB-73's embarked troops from Tango Company. Since the worms had originated in Karina's Progate Temple, Skywalker headed to the detention level to wheedle information on the parasites from Poggle.

It was not long before Skywalker rejoined Rex, Kenobi, Mundi, and Unduli on the bridge. After reporting Tano and Offee's predicament, Skywalker continued with the news that the brain worms were susceptible to cold temperatures. However, Skywalker evaded the other Jedi's queries as to how he had extracted the information from the so-far uncooperative Poggle. He relayed the worms' weakness to Tano, who accordingly neutralized them before TB-73 arrived at the Ord Cestus medical station, thus halting the outbreak.

Escapades at Saleucami
"It's the day I felt my life didn't have any meaning. Everyone I cared about, my team, was gone. I was just another expendable clone waiting for my turn to be slaughtered in a war that made no sense to me. Can you understand that, Rex?''" "''I've been in countless battles and lost many brothers. They were my family, my home."

"Sir, if I may address your accusation, I followed your orders. Even in the face of a plan, that was, in my opinion, severely flawed. A plan that cost us men. Not clones! Men! As sure as it is my duty to remain loyal to your command, I also have another duty. To protect those men.''" "You have a spark of tenacity, Captain. I'll give you that. I know that I don't command like the Jedi you're used to serving, certainly not like General Skywalker, but I have my way. It may be difficult, but these are difficult times. And it's proven'' effective. And I suppose your loyalty to your men is to be commended. They seem to admire this. That's important to an effective commander."

Your intentions are honorable, Rex, but defying the Council's order for a personal crusade&mdash;on a neutral planet, no less&hellip; That is not advisable." "With all due respect, General, this is not just a personal crusade.

Development for the series
"Rex keeps trying to wear the same armor; he's 'hybrided' his old armor into what you see now. And we thought that'd be kind of a good character trait for Rex to have, that he's welded his armor. It makes him more unique."
