DC Universe Online developers have let loose one angry undead bad boy in Solomon Grundy. WarCry has scored a bunch of concept art and screenshots of this ticked off zombie villain. Check him out:

Solomon Grundy™ is part zombie and part plant, a bizarre, centuries-old half-human life form filled with confused anger. At times he is a rampaging monster, at others a calculating and coldblooded villain.

Solomon Grundy's enhanced strength makes him a threat even to the DC Universe's strongest heroes. As an immortal, massive blows or injuries can't kill or hurt him - afterwards, he simply regenerates to rise again.

Solomon Grundy has been seen skulking in swamps, sewers, and abandoned buildings in both Metropolis and Gotham City. Denizens of these cities beware the low growl of "Solomon Grundy, born on a Monday..."
