A warrior devoted without question to Galvatron and the Decepticons, Nemesis Breaker is without a doubt, without pity; his heart is warmed only by the fire of battle. With a body design based on that of Leobreaker, he is the equal of that Autobot hero in every way, but with all sense of honor stripped away. He is a fantastically skilled fighter with the unfortunate talent of finding and making use of the weaknesses of almost any opponent.
