Well as many suspision have been running wild with regards to who the Arkham Knight might be one theory was it would be red hood. Meaning that Jason Todd might be in the game? Other theories involve it being that of Batgirl. Again this is nothing more than speculation as some still feel that a game company like Rocksteady games would never lie and that it is a completely original character. But with the Red Hood playable game pack it really makes me wonder at this point.
I guess only time will tell with less than a month to the release!
