Mad "Tongpu" Pierrot is an assassin who targets high ranking syndicate officials. He is highly skilled with all manner of firearms and is armed with an armory equal to a military platoon under his large coat. He takes a child-like enjoyment in killing and causing destruction, always arriving and leaving with a smile, always laughing when "working." Mad Pierrot was a patient in a program to develop a super soldier. The process was, however, too much for him to handle, and his mental state degraded to an almost vegetative state. As he was transported to his permanent holding cell after being removed from the program, he freed himself and killed everybody he encountered in the facility—all while smiling. Since the experiment made him bulletproof, Pierrot has never felt pain, and thus his mind collapsed when Spike made him suffer a minor leg wound. Pierrot died in a theme park, squashed by a giant robotic dog's foot.
