Star Wars: The Bad Batch Episode 7 Easter Eggs Explained
Clone Captain Rex returns to the Star wars animated universe! For those who don’t know, he’s a longtime character of The clone wars, just behind the central cast of Anakin Skywalker, Obi-Wan Kenobi, Padmé Amidala and Ahsoka Tano. In this show, he was often attached to Anakin and Ahsoka and developed a strong relationship with both of them.
At the end of The clone wars, Ahsoka succeeded with great difficulty in removing Rex’s control chip before the other clones could kill her as part of the new Order of Emperor 66. He must have seen the deaths of these clones firsthand, which led him to realize that they died on the wrong side of the war.
He has already encountered the Bad Batch as part of their mission to the planet Anaxes, where they together discovered that Echo was still alive after being captured and transformed by the separatists. Rex had loved Echo since they had previously served together and was distressed by the Separatists who had turned him into a living computer.
Rex turns out to be the person the Martez sisters contacted last week. It makes sense that he knew them, since he was close to Ahsoka, who first met Rafa and Trace in The clone wars. She probably put him in touch with the sisters. “Battle Scars” also implies that Rex is still in contact with Ahsoka herself as she tries to fight the Empire without getting a target on her back.
Omega notes that Rex is a “Gen 1” clone. It is not really a technical term that has been used with any specificity in Star wars in the past. However, it can be assumed that this is the first batch of clones, those deployed at Geonosis in Attack of the Clones.
Rex also mentions Fives, the clone soldier who discovered the inhibitor chips and was killed as part of the fallout from that discovery.
