In the Japanese anime adaptation Mutant Turtles: Choujin Densetsu-hen preserves the backstory from the 1987 TV series that inspired it. Unlike the rest of the main cast, Shredder's appearance was changed to match the Supermutants Shredder toy that was being sold at that time. The manga explained this by saying his original outfit was destroyed in a battle with the Turtles and that Krang created the new armor for him. Shredder also gains the ability to transform into his super-mutant form: the dragon Devil Shredder using the power of the Dark MutaStones he stole from the Neutrinos. With the energy from the evil sprite Dark Mu, he was later able to transform into the gigantic Dark Devil Shredder. In the second volume of the anime he gets his Tiger Spirit Metal Mutant armor. He was voiced by Kiyoyuki Yanada.
Saki's name was changed to "Sawaki" in this version because, in real life, the Japanese given name "Saki" is almost always female.
