Most Decepticons make violence their vocation, others see it as an art or a means to an end. For Slice, violence is everything. When confronted with a problem, he leaps into battle, lashing out with every weapon at his disposal until either he or his emeny is a smoldering wreck, even if that enemy is an uncooperative door. He loves smashing Autobots and humans but when confronted by other Decepticons, has a quick temper born of petty cruelty.

Slice followed Breakdown to Earth looking for new and interesting forms of ultra-violence. His Neuro-Centre Control Unit burned out after he landed in Toulon, France, sticking him with a thick French accent. He doesn't mind. It gives him an excuse to start fights with friends and foes alike.
