Turtle Saint

The Turtle Saint, also known as the Saint Turtle, is a character from the Teenage Mutant Ninja Turtles anime Mutant Turtles: Chōjin Densetsu Hen. The origin of the Saint Turtle lies in the MutaStones. The Turtles discovered an ancient Neutrino shrine and were given the MutaStones by the benevolent, fairy-like spirit of light, Kris Mu. These MutaStones were capable of transforming the Turtles into the sentai-esque humanoid SuperMutant Turtles. Furthermore, by crossing their arms together in a circle whilst holding the MutaStones, the four Turtles could merge together into one supreme being, the Turtle Saint.

Prior to the events of the anime's proper story, Shredder, Bebop, and Rocksteady obtain Dark MutaStones, and are easily dispatched by Turtle Saint. However, a crystalline cocoon, which contains Kris Mu's evil counterpart, Dark Mu, is nearing its hatching point.

At the end of the episode, Turtle Saint battles Dark Mu in outer space. The Turtles struggle to learn how to work together to control the Turtle Saint's movements, and Kris Mu grapples Dark Mu from behind, allowing Turtle Saint to strike with the Mega Final Saint Blade, which destroys both Mus and reverts them back to their crystals.

An action figure was released in Japan of Turtle Saint, which transformed from a chubby standard Ninja Turtle with the Turtle Saint's colors, into the form seen in the anime.
