Teenage Mutant Ninja Turtles: Superman Legend

OVA (2 eps) | 1996 | Ashi Productions

Combined, Donatello, Leonardo, Raphael and Michaelangelo make up the pizza-loving butt-kicking Teenage Mutant Ninja Turtles. With the help of mysterious Mutastones, the gang are able to perform a Super Mutation and transform into the powerful Super Turtles! However, the evil Shredder, Bebop and Rocksteady have their own dark Mutastone which allows them to similarly change into powerful foes. Along with their friend April and the wise Splinter, the Teenage Mutant Ninja Turtles will battle Shredder's gang and Krang, and even a long-dead ninja!
