now that I think about this the Arkham Knight doesn't act like Joker so it's probably not him.

Wouldn't it be funny if it was because you have all those people who don't want to see Joker in this game.

Wait he might be able to pull off the Arkham Knight. I mean he pulled off being Black Mask and noone noticed until it was revealed.
