Despite some mixed reviews, the DC Comics-themed superhero fighting game Injustice: Gods Among Us was a massive hit for Warner Bros. Interactive and NetherRealm Studios, and helped push a revival in the developer's better-known Mortal Kombat franchise. But a direct sequel to the hero-vs-hero brawler has only recently begun to take shape in Injustice 2.

Now, director Ed Boon has taken to social media to poll users about possible DLC characters. As reported by Game Rant, Boon is talking up the results of those polls - and who might make it into the final game.

Boon asked fans to respond to a pair of polls about the game's development, seeking their input as to which character from the Mortal Kombat franchise might make a guest appearance in the game via DLC and which character from another franchise entirely might appear as well, with four options for each. According to Boon, perennial Mortal Kombat "mascot" Sub-Zero won his poll handily, beating out Raiden, Johnny Cage and Jax:

The other poll, however, came back slightly less lopsided. When offered the choice of comic book superheroes Spawn, Hellboy, iconic movie cyborg The Terminator and TV vampire-hunter Buffy, a 45 percent majority of responders asked for Spawn to join the roster. Though Boon is enthusiastic, his posts stop short of outright confirming that the characters will officially appear in the final game.

An ice-powered ninja traditionally clad in a blue uniform and cast as the opposite-number of undead fire-powered ninja Scorpion, Sub-Zero has been one of the most popular Mortal Kombat characters since the series' inception. In fact, his infamous spine-removal fatality was perhaps the most iconic gore effect from the original game. Spawn, an undead zombie superhero who draws his power from hell itself, was created by Todd MacFarlane and enjoyed massive but short-lived success as a comic and merchandising behemoth in the mid to late-1990s.

Spawn has appeared as a Mortal Kombat guest star in the past, while Sub-Zero has encountered the DC Universe superheroes previously in Mortal Kombat vs DC Universe. This would be a first for both in the Injustice franchise, which is set amid a conflict between the familiar DCU and an alternate timeline where a tragic event involving The Joker has lead to Superman and several other heroes taking on dark, authoritarian personas and exacting lethal justice. The sequel was announced in June of this year, targeting a release date sometime in 2017.

Injustice 2 is slated for release sometime in 2017 for PlayStation 4 and Xbox One.
