Rollbar

Rollbar specializes in hand-to-hand combat. He is a skilled practiser of Crystalocution - the Cybertronic martial art of defeating an opponent by attacking his metal fracture points. He's also very interested in Earthen martial arts. Although described as "All-terrain terror", Rollbar prefers Arctic environments, and likes fighting on rainy days. He combines with his fellow Combiners to form the giant robot Ruination. Rollbar has a sarcastic sense of humour, which often shines through both amongst his team and when facing Autobots.
