Batman Arkham Knight: 10 Characters Who Could Be The Arkham Knight

5. Hush

This bandaged villain's true identity was, like the Arkham Knight's, kept very hush-hush (sorry) during the titular storyline that introduced him in the comics. He also cropped up in Arkham City as a serial killer who was running around the open-world prison, lopping off people's faces and attempting to nab the identity of his childhood friend...Bruce Wayne. It's not clear in Arkham City if Hush is aware of what his old pal does in the evenings, but if he's figured it out between games - we guess he didn't bother with Arkham Origins either - then it would make sense that he would start mimicking Bats along with Bruce. Perhaps by donning a costume that looks suspiciously similar to the famous cowl...?
