Since NetherRealm Studios has already unveiled all of the characters that will be included in Injustice 2's base game, with the Joker having been one of the last fighters confirmed, fans are almost certainly wondering which fictional figures from the DC Universe or beyond will make their way into the game via DLC. Thankfully, the developer's creative director, Ed Boon, has taken to his Twitter account to promise that news regarding expansion content in Injustice 2 will be "coming soon."

As seen in the tweet below from Ed Boon, not only did the NetherRealm Studios creative director assert that fans will receive the information in relation to the add-on materials with positivity, but also he attached a GIF of talk show personalities Conan O'Brien and Andy Richter clasping hands in excitement. Considering the fact that Boon is a notorious troll online when it comes to hints and teases related to games he and his team are working on, it would be extremely funny if the image of the comedians is an indication of O'Brien's superhero persona The Flaming C–from the host's 2013 Clueless Gamer segment for Injustice: Gods Among Us–making the cut for DLC in Injustice 2.

Aside from the unlikely, yet potentially hilarious addition of The Flaming C in Injustice 2, there has already been a lot of speculation from fans and suggestions from Boon himself in the past as to which characters are being considered for DLC. As it happens, the creative director has alluded to the possibility of Sub-Zero and Spawn being added to the fighting game, which could definitely be a possibility when one acknowledges that Mortal Kombat's Scorpion was added as post-launch content for Injustice: Gods Among Us.

Of course, Injustice 2's DLC characters could remain rooted in the DC Universe, and Boon has nodded to the potentiality of more unconventional heroes from the comic book publisher being a part of the game. To be specific, the NetherRealm Studios creative director took to his Twitter a while ago to gauge fans' interest in the addition of Watchmen characters for the fighting game.

Taking all of this into account, with Injustice 2's release date not far from now, it will be interesting to see if news of DLC materials "coming soon" means the information will be divulged before or after the game's launch. After all, Boon's definition of "soon" could be completely different than those of the fans'.

Injustice 2 is set to release on May 16, 2017 for PlayStation 4 and Xbox One.
