More than a year after the abrupt cancellation of The Clone Wars in 2013, the producers released four unfinished episodes online, believing they would never have an opportunity to complete the series. Some fans may be shocked to learn that's not where Echo's story ends, however. In the Season 3 episode 'Counterattack,' Echo seemingly sacrificed his life for his brothers in an explosion. If Fives sticks out more in your memory, it's likely because he ended up receiving a lot more screen time than Echo. It was in defense of the moon base that Echo graduated to the 501st Legion along with Fives, later being promoted to an elite ARC trooper.

Originally known for his fierce loyalty and dedicated discipline that caused him to repeat orders like an 'echo,' Echo was part of Domino Squad along with fan-favorite Fives.
