Dr. Drakken's cousin, notorious for his fleet of personal custom motorcycles, his distinctive mullet hairstyle, his playing of the air guitar, and repetitive use of the word "seriously!" Despite his seeming stupidity, he is actually a mechanical genius with a natural understanding of engines of all kinds, including rocket motors.
Though he is technically a villain because of his destructive actions and disregard for the law, he seems to have little interest in anything grander than road trips and "tricking out" his various rides.
He has an eye for "babes" and constantly hits on Shego, who wants nothing to do with him.
His name is a pun on the word motorhead – a term used to describe people who are heavily interested in cars and especially engines and possibly on the heavy metal band Motörhead, the members of which use a stereotypical "heavy metal biker" fashion.
Whenever he encounters Kim Possible, he never seems to use her name, only calling her by a self created nickname "Red", due to her red hair.
