Captain Rex (Voiced by Dee Bradley Baker) is the captain of the 501st Legion in Star Wars: The Clone Wars. His code name is CT-7567 and like most clones, he was born and trained on Komino to fight the Separatist. He's a loyal soldier to Anakin Skywalker, Ahsoka Tano and Obi-Wan Kenobi during the war.
He and two other clone troopers, Wolffe and Gregor are the only ones who took no part in Order 66 cause they find the order completely wrong.
They soon meet Ezra Bridger and the Ghost crew in Star Wars: Rebels and assist them to fight the Empire.
- Jeffrey and Jaden might meet Captain Rex in the future.
- Dave Filoni, producer of Star Wars: The Clone Wars and Star Wars: Rebels said he was thinking about making Rex the bearded rebel commando from Return of the Jedi.
