Killbison
- Killbison is a Decepticon Breastforce Warrior from the Victory portion of the Generation 1 continuity family.

Killbison (キルバイソン Kirubaison) 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 Breast Animal 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 every time he gets the spotlight.
(But does he kill bison? If he does, does he use every part, or does he destroy such magnificent beasts only for their tongues? Ah, the unanswered questions of life.)
