To an outside observer, the fact that the Teenage Mutant Ninja Turtles have lasted so long must seem like the most perplexing thing, with the group always having some new comic or cartoon or movie either already out or in the works.
However, to anyone with even a passing knowledge of the characters and their world, you know exactly why they've stuck around. Behind the goofy premise is a cast of unforgettable characters, dense, consistent world building, and a compelling story of family, science gone wrong, and the place of the different in society at large.
But even the most die hard turtles fan probably doesn't know everything about the characters, their history, or the fascinating stories behind their original inception. Sure, with this being the internet there's no guarantee that you haven't heard of at least one of these fun facts if you're in any way a TMNT fan, but that doesn't change how absolutely mind blowing they are.
From spin-off shows featuring fellow Mirage comics properties that very nearly happened, to very strange origins for important characters, these are the most mind-blowing facts about the Teenage Mutant Ninja Turtles.
