Timing, they say, is everything. Yesterday’s announcement that Green Arrow is joining the ranks of playable heroes in NetherRealm Studios’ Injustice: Gods Among Us leads nicely to tonight’s series premier of Arrow on The CW. Likewise, with New York Comic Con 2012 kicking off tomorrow (and Injustice making an appearance), today presents the perfect opportunity to unveil the game’s box art.

Cue publisher Warner Bros. Interactive, which did exactly that this morning. Cover art has been issued for all three versions of Injustice: Gods Among Us (PlayStation 3, Xbox 360 and Wii U), and in addition to depicting a knock-down drag-out brawl between Superman and Batman, the artwork reveals two previously unannounced characters: The Joker and Green Lantern.

Scratch two more candidates off Game Rant’s list of 25 characters that need to be in Injustice: Gods Among Us (specifically, numbers 1 and 16). Once the cover art started to make the rounds this morning, NetherRealm Studios Creative Director, Ed Boon, took to Twitter to officially confirm that Green Lantern and The Joker are in the game (he had actually teased both reveals yesterday – Green Lantern with a  YouTube clip of Kermit the Frog singing “Rainbow Connection,” Joker with a snippet of lyrics from the Steve Miller Band’s “The Joker”).

Now that we know Joker is in the game, the obvious question is: who’s voicing him? The best case scenario is that Mark Hamill takes the job, though it’s tough to gauge how willing he is to do so. Hamill appeared to be done with the character following his performance in Batman: Arkham City – he tweeted as much last October – though he subsequently indicated that he might be open to playing The Joker once again. Will Hamill announce his return to the role during NYCC? What do you think?

It’s probably too much to expect any more Injustice character announcements at Comic Con – three in one week is pretty substantial, particularly for a game that doesn’t release for another six months. Then again, you never know. In response to fan inquiries on Twitter, Boon has indicated that both Lex Luthor (“There’s always a chance we will be bringing Lexy back”) and Lobo (“Lobo is definitely in consideration”) are possibilities for the game, and where better than NYCC to officially announce them?

Ranters, if Hamill isn’t voicing The Joker in Injustice, who should do the honors? Leave your suggestions in the comments below.

Update: Boon has just released the first in-game shot of Green Lantern and The Joker. Check it out below.
