Repugnus is the most vicious, cruel and crude Autobot ever protoformed. A troublemaker since he was in the Autobot Academy, Repugnus and his two teammates eventually left the Autobots to become a trio of mercenaries, who hunt down criminals for profit... And fun. However, when it comes down to it, he hates the Decepticons as much as any other Autobot. Or maybe he just loves slagging Decepticons. We honestly don't know.
