Batman: Arkham Knight - 8 Identity Theories You Can Stop Believing

8. The Joker

Possibly an obvious one given how many interviews Rocksteady have given where they insisted time and again he's definitely, definitely dead, but it's not until the Arkham Knight tie-in comic where Joker finally has gets his autopsy and is pronounced fully, actually, unequivocally gone from this world. What's that? Yes, he does have a USB drive under his skin that emits laughing gas and then appears on TV to... no, no, he's definitely, absolutely 100% dead. Even if he isn't, the events of the comic show the Arkham Knight running amok killing a certain villain at the same time Joker's being carried off by the GCPD, so even if he IS still alive - which he most definitely isn't - it's not the Clown Prince under that mask. Probably.
