Knockout

Knockout from Transformers: Prime is a unique Decepticon with a very distinct personality. He's stylish, vain, and loves to keep himself looking pristine, taking pride in his appearance like few other bots. This vanity often leads him to prioritize his looks over practicalities, even in battle, which gives him a bit of an arrogant and flamboyant edge.

Despite being a medic, Knockout is also a skilled fighter and not afraid to get his hands dirty when needed, though he'd prefer not to scratch his paint. His personality combines charm with a streak of sadism; he enjoys inflicting pain and causing trouble for the Autobots. Knockout also has a witty, sarcastic sense of humor and isn't afraid to sass even his own allies, which makes him a bit of a wild card. His loyalty to Megatron is often questionable, and he sometimes looks out for his own interests first.
