A new trailer for Batman: Arkham Origins has been released, giving a glimpse of another one of the assassin’s that Batman will have to face off against over the course of the game.

The assassin’s name is Copperhead, a bit of a curveball given that the character is far less prominent that the other assassins. Copperhead recently had an overhaul in DC comics, changing from a man to a woman. It looks like it’ll be this overhauled version of the character that Batman goes up against, although the previous male version is hinted at.

Copperhead is a snake themed super villain, with the trailer showing off both her snake-like movement and hinting at some kind of poisonous attack.

Copperhead will join the other three announced assassins; Bane, Deathstroke and Deadshot in a fight for a 50 million dollar payout from “Black Mask.” With four revealed, that leaves another four still to be guessed. Presumably the other will be shown off in trailers similar to this one in the months before the game’s release.

Batman: Arkham Origins will be out on August 23 for PS3, Xbox 360 and PC.
