Forgotten Concepts of the 90's: TMNT The Next Mutation

The title says it all. Like "Dexter's Rude Removal", there have been many long forgotten concepts of various ideas for famous movies and cartoons. Some of them good, others...not so much. The Next Mutation is one of them. I'll start off by saying I am a big fan of the Ninja Turtles. Despite people calling it a kids' show, I have come to realize that there's more to TMNT than what people say. It's a story about four brothers who face incredible odds and challenges, overcoming them by working together. But on to Next Mutation. Back during the 90's this was suppose to be the fourth movie of the TMNT franchise. It would have been a big departure in how the turtles were portrayed, such as giving the character's powers and introducing a fifth turtle named Kirby, named after Jack "The King" Kirby, one of the greatest comic artists of all time. The idea was (thankfully) canned, but resulted in the short lived and terrible live action series, "Ninja Turtles: The Next Mutation." Here's a picture of one of the many concept art pieces of Kirby:

 It's for the best that this movie was canceled, or else it would have ruined the turtles forever.
