A custom t-shirt service seems like an unlikely place to find new assets from a major video game release, but an account on Zazzle.co.uk has apparently delivered exactly that! Months of speculation has apparently ended with the reveal of Ares and Killer Frost via the on-demand merchandise maker.

Ares has been a contender for inclusion since being referenced by Official PlayStation Magazine Australia during their January preview. The God of Wars' helmet has since joined a range of avatar accessories available for sale on Xbox LIVE [full story]. Killer Frost featured in S.T.A.R. Labs Missions previewed recently at live events.

The artwork [pictured above] appeared amongst an extensive range of rendered characters, reported last week [via Test Your Might]. All products have since been removed.

The inclusion of the two villains elevates the playable roster to twenty-four characters. At least four more characters will find their way into the game via additional downloadable content [full story]. Blackest Night Batman technically constitutes another character -- available with Blackest Night pre-order deals [full story].

Injustice: Gods Among Us is mere weeks away! Fans can get their first taste via a free demo starting April 2 [full story], before the full game ships April 16 (US). Discuss all things Gods Among Us on the DC Universe Injustice forum!
