Rollbar is the Mini-Con partner of Scavenger. His strength is impressive, even to his larger Autobot teammates. In vehicle mode, he is able to overcome rough terrain and rougher enemies. Decepticons and enemy Mini-Cons never challenge Rollbar without a solid plan of attack. When powerlinked with Scavenger, the two are nearly unstoppable, able to bulldoze their way through an army of Megatron's greatest warriors.
