Leader of the Decepticons, aimed at conquering Cybertron and doing what he views is returning the planet to its golden age. He's clearly out of his mind, stating that no cost is too high and he feels that anything that doesn't at least stay out of his way must die.
Determinator: Protest as to the otherwise absolutely suicidal nature of the current mission, he will roar for the course to be stayed. Even if it means ramming a frigate right into a space station, while he's on the bridge.
Deadpan Snarker: Breakdown seems to have a particular gift for bringing it out of him.
Megatron: "Into the tunnels, Decepticons, and try not to be crushed by the trains."
Villainous Valor: One of the main reason the Decepticons are loyal to him despite being a Bad Boss, he's not afraid to do anything he'd order them to do himself, probably part of why his men running from a fight ticks him off so much.
