^ I believe in...Buttmunch.
The best outcome, yet also the hardest to believe, is that it's a minor or hinted character from arkham asylum, that was indeed non-existent before, and has been hinted toward the whole time, and it's a brilliant Prestige to the whole series. For some reason I can see them having thought of this new villain from the beginning.
It could also be a new characters that's in some way related to an existing character. The thing is, he needs some tie-in to the franchise and/or Batman-world. Else it's just literally a new character that pops up and it seems very hard to me to actually make that character engaging.
Personally I thought of something like Quincy Sharpe's son, someone who has been indoctrinated by the whole Arkham thing his whole life. Or a descendent of Amadeus Arkham or something.
The whip looks like the same one that was on fixed to her leg on the previous release.
