Teenage Mutant Ninja Turtles: An Ultimate Mutation

Teenage Mutant Ninja Turtles: An Ultimate Mutation is an American/Japanese cartoon series, mainly in New York City. It is also inspired by 2003 series and IDW comics. The Turtles' faces are reminiscent of Shoutmon from Digimon Fusion. The mutagen is depicted as having similar properties to the version seen in the Mirage comics and 1987 series; It blends the victim's genetics with that of whatever creature they have recently touched, but when used on animals, it makes them a larger, more intelligent, human -like creature.
