Rampage is a cybernetic bull that roamed the Iron Mountains until he is landed upon by Handlebar.  After a fight that ensues in which he is saved by Handlebar from falling off a cliff into a pool of lava he isbefriended by Handlebar. While Handlebar was rushing to the aid of Bravestarr and Thirty Thirty to fight Krang slavers Rampage puts Handlebar on his back and aids by ramming the slavers ship repeatedly. He is last seen in the PSA after the show licking Handlebars face.
