Ray (1987 TV series)

Ray is an evil fish mutant that was introduced in the 1987 series episode Rebel Without a Fin. He was created by Dr. Polidorius. April O'Neil is kidnapped and mutated into a fish-woman in an effort to provide a bride for Ray.

Notes/Trivia
Ray was originally meant to be Man Ray/Ray Fillet, a character prominent in the Teenage Mutant Ninja Turtles Adventures comics. However, creator Ryan Brown and Adventures writer Stephen Murphy objected to the character being used as a villain, and thus, the writers were forced to change the character into an unrelated fish mutant with a similar name.
