Tano Ahsoka Star Wars: The Bad Batch, Episode 7 concludes with Captain Rex phoning an unknown Rebel ally, and while many thought he was speaking to Ahsoka Tano, this may not be the case. In the final scene of the episode, we see Rex standing on a street corner in some type of foreign city, looking around at all the neon signs and whatnot. He seems quite content standing alone in his hometown, so it's possible that he made contact with someone else during his time away from duty. Rex is one of the main characters in the Star Wars Rebels TV series, and he first appeared in Season 1, Episode 3 - titled "The Ghost." In this episode, it is revealed that he has been hiding out on a desert planet after being accused of killing Chancellor Palpatine. It is also shown that he has become obsessed with finding Master Yoda, so he can ask for help in stopping the First Order. At the end of this episode, it is hinted that perhaps Rex will meet up with Ahsoka again someday. In addition to appearing in Rebels, Rex has also made several other appearances outside of Star Wars. He first came to life in 2003 when Disney created a new Star Wars character named Rex Dalgas.
