Badass Grandpa: He's the oldest-sounding of the Autobots, and is still strong enough to offline two Brutes within five seconds and with his bare hands.
Blood Knight: During his stage, almost ever word he utters is either a hilarious joke, or about how much he loves the fact they're stuck in a Decepticon prison.
Fun Personified: Constantly trying to give Bumblebee a nickname.
Composite Character: He has the name of Zeta Prime, but is more or less Sentinel Prime in that he precedes Optimus Prime. Transformers Exodus makes it worse by calling him just that.
Badass: You try to tell him he can't do something like, say, defeat the entire Autobot army and decapitate it? Or maybe taking down the frighteningly huge and powerful Omega Supreme? He will do it anyway.
Bad Boss: To the regular Decepticon soldiers, if they dare protest. If the named officers complain or try to suggest a less suicidal alternative, though, he'll tell them to shut up.
"Unacceptable! They should be victorious, or dead!"
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."
Only Sane Man: He's really the only Decepticon seen who isn't bloodthirsty or fanatical, and by the sound of things would prefer some scientific study of Cybertron's literal underworld.
Breakdown
Bunny-Ears Lawyer: Despite his nerves and whining, he's fast and a competent soldier otherwise.
Butt Monkey: Megatron snarks and yells at him the most. If only because he's the only one that doesn't get executed for back talk.
Cowardly Lion: He's always whining about Megatron's suicidal plans, but he's still up there with him at the front.
The Starscream: According to his Hall of Fame profile, he dreams of ruling Cybertron himself after reformatting everyone on the planet to a new form of existence. In Transformers Exodus, Megatron even suspects that, one day, Shockwave will turn on him.
