Teenage Mutant Ninja Turtles - S01

When the Teenage Mutant Ninja Turtles receive Mutastones from Crys-Mu, the spirit of light, they gain the power to temporarily transform into Super Turtles for three minutes. At the same time, their nemesis Shredder and his henchmen Bebop and Rocksteady discover the Dark Mutastone, turning them into Devil Shredder, Supermutant Bebop, and Supermutant Rocksteady. But the Turtles have a final advantage-they can merge into their strongest form, Turtle Saint.
