Cliffjumper

"Let me at 'em" is Cliffjumper's motto. His eagerness and daring have no equal. He's driven by a desire to win the battle against the Decepticons. Finds Earth terrain a hindrance. One of the fastest Autobots. Often uses his speed to draw fire away from others. Shoots "glass gas" which makes metal as brittle as glass. His recklessness often leads to actual blow-outs and situations too dangerous for him to handle.
