Pizzaface
What's hilarious is that he isn't really a mutant, just a typical unhygenic short order cook. Pizzaface tried to mutate himself by sticking his head in a Retromutagen oven (!!!), but the Turtles found him and pulled him out to safety. Now he attacks them in revenge. The orginal prototype for the toy had a meatball-shaped conjoined twin on the top of his head, and his missing finger was explicitly chopped off in order to serve it to the Turtles on a poison pizza. Even when they toned him down, Pizzaface is still extremely gross.
