Todo 360 is Cad Bane's techno-service droid, a 0.66-metre unit packed with built-in gadgets. StarWars.com describes "a hard worker with an attitude to match, especially if you try to call him a butler droid" — a running joke the animated series returns to whenever it needs to puncture Bane's composure.
He is functionally the tool that makes Bane's heists possible: cutting, slicing, carrying charges, and on at least one occasion being used as a bomb without being consulted first. He appears in both The Clone Wars and The Bad Batch, making him one of the few droids to survive the entire span of Bane's career.
