Teenage Mutant Ninja Turtles copycats were common throughout the '90s. No surprise, since Ninja Turtles remains one of the most famous cartoons/franchises of all time. It's spawned comic books, movies, video games, four different animated series, a live-action series, and more toys than you can shake a stick at. So it's no wonder the premise has been ripped off more times than the fat guy/hot wife sitcom formula.This list presents some of the most ridiculous and obvious Teenage Mutant Ninja Turtles knockoffs to ever grace TV screens and toy shelves. These are the animated shows that blatantly aped TMNT in cash-grabbing attempts to capture the imaginations of children and the wallets of their parents.
