... sure any Batman comics that were released resembles the Batman in Batman v Superman. So it is very likely that they would want the game, Arkham Knight, to also follow. Just like a few of you have said below, Jason Todd was branded with a J below his eye, just like Jared Leto's character. If the Joker really is Jason Todd, it would explain the tattoos and his teeth. Joker beat the shit out of Jason Todd and probably knocked all his teeth out. The tattoos would explain his obsession with Joker or more branding from the Joker. I love this twist and I hope it's true.
