It doesn't have a true name, being created and born in a laboratory and all. It's considered the most successful mutant as of right now, with a fast running speed, strong fighting ability, and aggression giving it a will to fight and win.
It is considered mandatory to keep the muzzle on it at all given times except for eating and bathing to avoid injury to other mutants or laboratory workers.
