Star Wars Cassian Andor: 10 Rebels Characters Who Need To Appear
2. Captain Rex
Captain Rex was arguably one of the best clones that appeared in The Clone Wars. His popularity among the fans secured him not only a place in Rebels but also in the Original Trilogy - Dave Filoni, creator of both animated shows, has confirmed that one of the older soldiers seen in Return Of The Jedi was indeed Captain Rex.
He remained loyal to the Galactic Republic, despite most of his brothers joining the Empire and, later, served Rebel Alliance.
It'd be good to see him in live-action Star Wars one more time, even if for a single episode.
