...what's going to happen when turtles meet bat?
Although I enjoy the stories one sometimes still finds in the good ol' four-color funnybooks, I don't buy very many anymore, because many of them are busy proving Sturgeon's Law.
But for a Batman meets Teenage Mutant Ninja Turtles crossover? Messing this up would take a lot more creativity than a lot of comic writers demonstrate today, so it could be very interesting. I like the writer at Uproxx's suggestion, too. When the Turtles first appear in Gotham, nobody pays them much attention. In a city menaced by a guy dressed as a penguin and protected by a guy dressed as a bat, how odd would four speaking, human-sized turtles really be, anyway?
