Rex appeared as a prominent character in the series, who is in several episodes. He is good friends with Anakin Skywalker, Cody and Ahsoka Tano. He was the only one besides Anakin who saw right away that Ahsoka was being framed and was devastated when she refused to rejoin the Jedi Order. He was also devastated when ARC trooper Fives died, as they had known each other since fighting together to save the Rishi outpost. He is tough and loyal, evidenced when Asajj Ventress interrogated him and he refused to talk. At some point after Fives' death, Rex had his inhibitor chip removed and possibly deserted the army; with Commander Appo succeeding him as the leader of the 501st by the end of the war. As such, Rex never took part in or fell under the sway Order 66 like most of his clone brethren did.
Rex appears in the second season of Star Wars Rebels where he is the leader of a trio of Clone Wars survivors - he and clone officers Wolffe and Gregor, living on an old AT-TE somewhere in the Seelo system. Rex and his brothers are surprised by the arrival of the Jedi Kanan Jarrus, and quickly, Wolffe and Gregor quickly open fire. Kanan, however, deflects them back, but Ezra Bridger, Kanan's apprentice, stops the fighting.
As the rebels and clones bond, Kanan still has sour feelings for the troopers, but Ezra looks up to Rex. As Rex puts together a list of locations for possible rebel bases, Garazeb Orrelios, Sabine Wren, Ezra, and Kanan help Gregor and Wolffe hunt for a giant worm. However, unbeknownst to the rebels and Rex and Gregor, Wolffe contacts the Empire and gives them the rebels' location. An Imperial probe droid zones in on them, and gives their location to the Imperial command.
Rex and Kanan then confront Wolffe about his betrayal, and he replies that he simply wanted to protect his brothers. He then joins the rebels and clones as they battle the probe droid and wait for the arrival of the Imperial war machine. When Imperial Agent Kallus arrives with three Imperial AT-AT walkers, despite losing one to a sandstorm, Kallus has the other two, including the one he's piloting, engage Rex and the other clones as they buy time for the Lothal rebels to escape. However, the clones' AT-TE is no match for its Imperial descendants, and just as Kallus is about to finish them off, Kanan and Ezra return to commandeer the second AT-AT with Zeb, turning it on Kallus' until Rex delivers the killing blow with the main cannon of the AT-TE to the lightly-armored neck of the AT-AT, its weak spot. Kallus and his pilots escape, and the clones join the rebels, allowing Rex to reunite with Ahsoka, calling her "Commander" as he did during the Clone Wars.
Some time later, Rex joins Ezra and Zeb to collect proton bombs from a wrecked Separatist ship, only to find a collection of battle droids still operational under the command of Super Tactical Droid Kalani from the Onderon occupation during the Clone Wars. Kalani had prevented his droids from being deactivated when Darth Sidious and Darth Vader sent out the call for the Separatist Droid Army to shut down following Vader executing Trade Federation Viceroy Nute Gunray and the other Separatist leaders, ending the Clone Wars, as Kalani wanted to end it on his terms. However, when the Empire arrives to the area, Ezra convinces Rex and Kalani to put aside their differences and focus on escaping from the Empire, whom Ezra logically tells Kalani are the real tyranny that the Separatists had been fighting against since the Empire was originally the Republic. As they prepare to flee, Rex calls it "the last day in the Grand Army of the Republic" as he prepares for battle. Once they escape the Empire, Kalani and his surviving droids part ways with the rebels, but not without agreeing with Rex that, thanks to Ezra, they could finally consider the Clone Wars officially over and make peace with each other.
Rex was with some of the other rebels when he receives Senator Mon Mothma's call to unite into a single Rebel Alliance to face the Empire together. However, they are soon forced to abandon their base on Atollon when their location is compromised by Grand Admiral Thrawn knowing where they were and taking Agent Kallus, who was now a Rebel spy, prisoner. Both Phoenix Squadron and General Dodonna's combined fleets are no match for Thrawn and the Imperial fleet from Lothal, blocking their escape with two gravity well generator-equipped Interdictors, and tearing the combined Rebel fleet apart, forcing the remaining survivors to return to Atollon, where they are soon surrounded by Thrawn and his troops. However, before Thrawn can execute them, he is interrupted by an unnatural storm created by the Bendu, who demands all Rebel and Imperial forces to leave his planet at once or face annihilation by him. The distraction allows Rex, Hera, and the surviving Rebels to flee, while a Mandalorian strike team led by Ezra and Sabine take out the remaining Interdictor after Commander Sato sacrificed himself and the Phoenix Home to take out the first one. Having escaped Thrawn and his forces, the surviving Rebels make haste retreating to Rebel Headquaters on Yavin VI.
Friends and Allies
During the Clone Wars, Rex and Anakin led the 501st and fought together side by side against the Separatists. Rex is very respectful to his general and obeyed his orders usually without question. However, it is unknown if Rex is aware that his general had turned into a Sith Lord; Rex was no longer in command of 501st when it marched on the Coruscant Jedi Temple during Order 66.
Rex first met Ahsoka during the Battle of Christophsis, when she was assigned to Anakin Skywalker as his apprentice, throughout the Clone Wars the two became good friends.
Initially, Ahsoka believed that because she was a Jedi and he was a captain, that she outranked him, but Rex told her that experience outranks everything; he soon developed a high level of respect for her, as the captain became somewhat of another mentor to Ahsoka, particularly in warfare. The two often saved each other's lives during the Clone Wars and shared a friendly bond similar to the bond Ahsoka shared with Anakin, but not quite as close. Nearing the end of the Clone Wars, Rex also held a high degree of trust in her, being one of the few people that were doubtful of her being guilty of committing murder and bombing the Jedi Temple. His reaction to her departure from the Jedi Order is unknown.
When meeting the Ghost crew, Rex told them that any friend of Ahsoka's is a friend of his, showing that they still have a close friendship sixteen years after her departure from the Jedi Order and renouncing her command position in the Grand Army of the Republic. Rex was deeply saddened when he learned of Ahsoka's apparent death on Malachor.
During the Clone Wars, Rex and Obi-Wan worked with each other on some of their missions together, Obi-Wan agreed with Cody that Rex is a smart man and believes that he always thinks on his feet. It is unknown if Rex and Obi-Wan ever saw each other after Order 66; before the latter was killed by Darth Vader.
Rex serves as a grandfather-figure to Ezra. While Ezra finds Rex very interesting because of his past as a soldier and being in the Clone Wars. While Kanan refuses to trust Rex, Ezra believes they can, he also becomes somewhat of another mentor to Ezra, particularly in warfare.
Kanan was initially distrustful and hostile towards Rex and his fellow clones due to the events of Order 66. When they went undercover as stormtroopers to rescue Ezra, Commander Sato, and his crew, they managed to work together well in a way reminescent of the Clone Troopers and their Jedi Generals during the Clone Wars. After this, Kanan finally put his animosity towards clones behind him when he gave Rex a salute of respect, which the captain gladly returned.
Rex and Kallus initially started out as enemies; Kallus regarded the Clone Troopers to be obsolete and not a real threat whereas Rex bravely goaded Kallus after refusing to stand down or give up the rebels he was aiding. Kallus chose to make an example of Rex and his men, only to underestimate them and be sent running with his tail between his legs.
Later, when Garazeb Orrelios indirectly recruited Kallus into the Rebel Alliance, going under the codename "Fulcrum", becoming one of the rebellion's informants, the two would become allies.
Like Anakin, Rex respected and admired Palpatine for his clean slate. However, unlike his Jedi General, his respect for the Supreme Chancellor was never to the point of having a blind spot for him. When Fives told him and Anakin about Palpatine's role in a conspiracy involving the bio-chips implanted in the Clone Trooper brains, Rex was able to discover the truth from his last words and promptly removed his bio-chip, as well as convincing Wolffe and Gregor to do the same.
Rex initially respected Pong for his victories. This respect was gradually lost during the Battle of Umbra by Pong's arrogance and disrespect for him and his men. Things came to a head when they fought each other. When Kreel was imprisioned, Pong revealed his true colors as a power-hungry sadist who loathed the Clones as "creatures bred in some labratory" and who had turned traitor.
- He was confirmed by Dave Filoni to be one of the Rebel Alliance soldiers on Endor during Star Wars: Return of the Jedi.
