Mutants

A mutant is any being who has been exposed to mutagen or in some other way has undergone some form of transformative mutation.

Definition
The idea of a mutant is a common trope in comic books and science fiction. The new phenotypes that appear in fictional mutations generally go far beyond what is typically seen in biological mutants, and often result in the mutated life form exhibiting superhuman abilities or qualities.

Within the realm of TMNT, the term "mutant" is almost exclusively used to describe any being who has been affected by mutagen, rather than any naturally occurring mutations. Mutagen can mutate a being in numerous ways, ranging from animals taking on human traits (such as The Ninja Turtles and Splinter) to humans taking on animal traits (such as Bebop and Rocksteady), to either taking on the traits of other objects (such as Muckman) or simply growing in size and strength (such as the Super Shredder). The 1987 TV series stated that whatever was being mutated would take on the traits of the last living thing it touched. This is not stated in any other series, and would seem contradictory in many cases.

The Mutagen exposure is the same in the 2012 series. According to a Kraang operative in Pulverizer Returns!, the Mutagen's effects are unpredictable. It was also shown that if anyone is exposed to Mutagen and hasn't come in contact with anything animal or plant-related, they will end up turning into a mutant blob. The Mutagen is shown to not mutate anyone who has some Kraang DNA in them.
