8. Green Arrow
There was a lot of talk about Arkham City's sequel featuring more members of the Justice League - perhaps porting back to the Golden Age - and while that didn't happen (perhaps expect it in future,) one Justice League associate does have a perpetual presence in Gotham City during Arkham Origins. Though he doesn't actually appear (DLC?) Green Arrow is teased by one unavoidable reference to the company run by his alter-ego Oliver Queen - Queen Industries. Green Arrow probably fits the Arkham game model the best given the opportunities provided by his island home, and the similarities between the two characters, so this nod could be a hint at what we can expect to see in future, either from this game, or a spin-off. There's also a Queen Industries reference in the trailer for the game...
And if those two references weren't enough of a hint that Green Arrow is probably going to appear in some way, there was also a second nod in the trailer, a little more obscure this time. As the image below shows, there's a logo in the background of the trailer that looks suspiciously like the welcome sign in Star City - home of Green Arrow...
