After obtaining powerful Mutastones from Crys-Mu, the spirit of light, the Teenage Mutant Ninja Turtles unlock the ability to transform into Super Turtles for a brief three-minute window. On the flip side, their adversaries Shredder, Bebop, and Rocksteady chance upon the malevolent Dark Mutastone, evolving into the formidable Devil Shredder, Supermutant Bebop, and Supermutant Rocksteady. However, the Turtles hold a secret weapon in their arsenal: the ability to merge into the awe-inspiring Turtle Saint, their ultimate and most powerful form.
