Knock Out is a Decepticon medic and scientist in Transformers: Prime. He serves as the team’s sleek, vain, and highly self-assured medical specialist, often more concerned with style and status than battlefield efficiency. Despite his arrogance, he is skilled in repair, experimentation, and analysis, making him a valuable asset to the Decepticons. He frequently interacts with Breakdown and later becomes more conflicted about the war, adding depth to his role as a recurring villain with occasional moral hesitation.
