Batman: Arkham Knight - 15 Hidden Easter Eggs, References & Secrets You Need To Find

Rocksteady are clearly having a blast putting together any number of character threads they can pull at for future releases, should the need arise - yet one of the most tantalising outside the Superman rumours is a fully-fledged Green Arrow adaptation. Considering the overwhelming success of the TV show - that's currently undergoing its own Avengers-style overhaul to incorporate The Flash and many other characters - Arrow could actually make for a brilliant follow-on for the developer as their next project. With the huge amount of potential you can do with Queen's backstory and a potentially more brutal fighting style that Batman's, a Green Arrow game that springboards off from the Arkham trilogy in tone and approach makes more sense the more you think about it.
