Wasp (Transformers Animated)

Wasp, who later becomes the Predacon Waspinator, was originally an Autobot. He was of the same type as Bumblebee, whom he attended boot camp with. Wasp's pompous, smarmy personality leaves something to be desired, but he had a lot going for him as a soldier, being highly skilled in the use of his stingers and knowing just how to tow the line with the drill sergeant. In a better life, he might have been Cybertron Elite Guard commander material were it not for the chain of events that scarred him and led to his current state.

History
Before the events of the series, Wasp was a cadet along Bumblebe and Bulkhead, who along with Longarm Prime often teased Bumblebee and Bulkhead, The loud-mouthed drill sergeant Sentinel Minor took an immediate liking to "Wasp", as he dubbed him. Wasp and Ironhide quickly became close friends, often competing in little tests of strength, usually involving Wasp hitting or stinging Ironhide while the latter was in armor mode.

After Bumblebee "bumbled" several times, leading to many problems for the whole group, Wasp and Ironhide decided to take matters into their own hands, unscrewing Bumblebee's lower legs and leaving them out of reach even before they dumped the rest of him in a locker.

Unbeknownst to Wasp, however, the reason for Bumblebee's foul-ups was that he was trying to out a traitor in the group—and had pegged Wasp as the likely culprit after seeing him walk out of a hangar in which someone had contacted Megatron and the fact that Wasp is clearly like a Decepticon due to his attitude. With the aid of Longarm, Bumblebee eventually found evidence incriminating Wasp as a spy. Wasp was stripped of his Autobot insignia and wheeled away, protesting his innocence and swearing revenge on Bumblebee.
