Killbison is the stereotypical violent jock of the Decepticon Breastforce team. He transforms into a double-barreled tank, and like all tanks, his barrels will either be (a) bent backwards (b) yanked at or (c) made useless once the first step has been completed. His Breastforce partner is Bisonbreast, a winged bull, who does not fly and is not red. This does not keep Killbison from joining with his fellow teammates to form Liokaiser. His hobbies include throwing knives at pictures conveniently hung on doors, and giving the finger everytime he gets the spotlight.
