Poor old Jason Todd, what a life he's lead. The second Robin was so hated by fans that they voted he be killed off by The Joker back in the day, only for him to resurface recently in the guise of hard-line vigilante the Red Hood. With an understandable dislike for ole Bats who failed to stop his arch nemesis clubbing Jason to near-death with a crowbar, he's in the process of eradicating Gotham's criminal element in a similarly permanent manner to the Reaper - only with guns instead of scythes. Also he wants to kill most of the Bat-Family, loads of police, and really anyone who gets in his way. Jason has to be the top pick for who the Arkham Knight could turn out to be. He's got a similar outfit, his back story would make him a natural fit for a rougher, tougher alternative to Batman who comes to blows with his former mentor, plus he's been teased as the secret identity of countless mysterious characters in the comics - including Hush - so why not the Arkham Knight too? Who do you think it is? Hopefully E3 will shed more light on the identity of the Knight, but until then let us know in the comments!
