Batman: Arkham Knight - 10 Killer Ways To Resurrect The Joker

5. Identity Theft

In the above clip we see Hush reveal his master plan to gain revenge on Bruce Wayne in Arkham City, by stealing the skin of six other people to form a Bruce Wayne mask. Hush will, no doubt, make an appearance in Arkham Knight based off of this and the way the side quest is left open-ended. With Dr. Thomas Elliott (aka Hush) looking to drag Bruce's name through the mud, perhaps he finds out Bruce is actually Batman? And if that's the case, and if Dollmaker isn't present in the game, why not have Hush steal Joker's face and assume his identity? It's not completely outside the realm of possibility, and could even open up the potential of having Harley Quinn work as Mr. B's reluctant ally (something we saw similarly in Injustice: Gods Among Us). Since Harley is, in fact, going to be a pre-order bonus playable character, maybe Rocksteady will give us some Harley-inspired side missions to deviate from the main story a la Catwoman in Arkham City? Poison Ivy hinted that she would be out for revenge against all humans in Arkham City (laying the groundwork for a return in Arkham Knight), Robin tangled with Harley in the Harley Quinn's Revenge DLC, so Harley could have other missions involved with those two, as well as fighting Hush over the desecration of her beloved Mr. J's corpse.
