10 Mind-Blowing Twists In Star Wars: The Clone Wars
8. Echo Is Still Alive
During the aforementioned season three Citadel arc, Anakin and Obi-Wan were joined in their mission by Captain Rex and some of his most trusted troopers, including fan favourites Echo and Fives.
As the group attempted to make their initial escape, Echo and Fives tried to gain access to their getaway ship, with Echo breaking away in a last-ditch attempt to save the day. Unfortunately, this didn't work, and Echo was blown up alongside the cruiser and presumed dead.
In the final season, though, Rex and Anakin made a startling discovery when they found Echo alive and being used to give up vital battle plans to the Separatists.
Rex saved him despite his injuries and the experimentations that had been done to his body, and when their latest mission was complete Echo decided to go off with the Bad Batch, a group of abnormal clones known for their unconventional battle tactics.
With his new squad, Echo is currently enjoying life on their self-titled spin-off, set after Order 66.
