Only if my idea of a giant mutated sperm cell who by day is as a subway mariachi performer and by night a criminal mastermind can be his arch nemesis. Jealous of The Fetus' many cells and further stage of development he and his Marichi's of crime try to thwart the Fetus on his vigilanti style quest for revenge at every turn. The other Mariachis of crime are all regular Mexican fellows, except for one who is actually secretly Colombian.
