The youngest and fastest of the Autobot Brothers, Side Burn rockets down highways in his Dodge Viper mode for fun, in pursuit of an enemy - or chasing after his latest flame. Because that's Side Burn's greatest weakness: the ladies. Every time he sees a little red sports car, he's falls in love all over again, but can't seem to comprehend that Earth cars aren't alive. Despite his flaws, he is a courageous and sympathetic Autobot, always ready to defend those whom he cares about. He also displays a sense of humor, something he thinks his older siblings lack.
