Optimus Primal
Quote: "What's that, Boastful Fist?  You wanna kick some tail?"

He's died more times than Optimus Prime, but that doesn't keep Primal from forever thwarting Cheetor from his leadership role in his Queen Elizabeth II style.  Usually calm and reverent, Primal will kick your ass if you call him Buddha Monkey or even allude to the idea that he resembles the not-quite-as-hip and swank Laurence Fishbourne.  He occasionally will make Cheetor some pie, but won't let him eat it without his mittens.
