Road Rage is the bodyguard and advisor of Cybertron ambassador Crosscut. She is well-versed in alien cultures and generally cheerful, making her a very good diplomat. However, a chronic short-out in her vehicle mode causes her to live up to her name; in car mode, she is a snarling, swerving speed machine with little regard--if not utter contempt--for anyone else on the road with her. This is pretty embarrassing for her once she reverts to robot mode.
