Formerly the Pulverizer, who mutates into a jar of goo, then Mutagen Man. He absorbs any Ooze around him for fuel.
Being mutated from nothing but a tube of guts to an armed and legged jar with acid Ooze hands, he searches for April
in hopes of finding a friend and fights anything that gets in his way. His acid Ooze hands melt anything they touch,
so the Turtles fight to keep him away and Ooze free in order to find a cure and reverse the mutation.
