|Biff's Gang, circa 1955, Skinhead is on the right.|
|Occupation:||Bodyguard for the CEO|
At some point before 1955 he, Match, and 3D would befriend Tannen and form a four person gang throughout their high school years. They were forever in trouble with school authorities and were frequent tormentors of George McFly. They were also serious obstacles for Marty McFly during his first and second temporal incursions. (Back to the Future Part II)
In the hellish alternate reality of the Biffhorrific Hill Valley, Skinhead would serve as a longtime bodyguard of Biff under the employ of BiffCo. As such he would be one of the first to become aware of the existence of Armus and would accompany Biff, along with Match and 3D. (Star Trek: Voyager - Dark Realm)
Of the three members of Tannen's gang, Skinhead was the most fanatically loyal. Where Match followed due to fear of Armus and 3D was desperate to redeem himself for his failure to find the flux capacitor, Skinhead followed Biff's orders to the letter.
He appeared to show sadistic personality traits while interrogating Marty McFly using a soldering iron and a mid-level pH acid on the burns inflicted by the soldering iron. (Star Trek: Voyager - Dark Realm)
