Side Burn is an adolescent speedster and turbo-revving young punk. His brain development has yet to catch up with his ego and robo-hormones, and if he gets bored or preoccupied he'll wander away from his assignment or get in the way of someone else's without a second thought. This is particularly annoying to his law-abiding brother Prowl and the fussbudget Autobot computer known as T-AI. Even the more easygoing X-Brawn can grow tired of his antics. They're no fun anyway, and he can always outrun them. He can outrun just about everybody and everything except his own foolishness.
