8. Jason Todd
Like Hush, Jason Todd is considered the odds on favorite to be revealed as the Arkham Knight. In fact it's so obvious that Todd is practically guaranteed NOT to be the Knight. The second Robin was infamously beaten to death by the Joker in the Death in the Family story (he was such an unpopular replacement for Dick Greyson that fans actually voted for his death). However he was resurrected by Ra's al Ghul and he took on the mantle of the Red Hood, ironically the alias previously used by the Joker. Red Hood has since become DC's answer to the Punisher, an anti hero who targets villains but uses lethal force. Though Todd hasn't appeared in any Arkham games so far, fans will have obviously noticed that Dick Greyson was using his Nightwing alias in the DLC pack and the version of Robin we got was Tim Drake (the third Robin). There couldn't be a Tim Drake if Jason Todd hadn't already come and gone. Throw in the fact that Ra's al Ghul and the Lazarus Pits already exist in the Arkhamverse and we have the possibility of a revitalized and revenge-motivated Red Hood, literally gunning for our cowled hero. Further speculation arose earlier this year when a Red Hood DLC pack was announced. Some saw this as 100% confirmation that Jason Todd was the Arkham Knight, whereas others believed Red Hood would be a separate character entirely. All that is really set in stone is that Jason Todd is finally confirmed to make his Arkhamverse debut, and we for one can't wait to play as the character.
