A writhing mass of red tentacles
The RJD2 series virus, affectionately known as The Red Scribble, is the scourge of cyberspace.
"I have seen the beast, tentacled and cruel. Tore out me eye, it did, like pickin’ a plum. It’s cursed, I tell ye, cursed to its cold heart."
-Jerboam the Sailor
Misunderstood and much maligned, the Hek is a traveller who dreads violence. If it only understood the violence it caused.
From an episode of Justice League Unlimited:
The God of War creates a giant, unstoppable robot (golem, animated armor, etc.) as a weapon for one side in a civil war; his purpose is to prolong the war and create suffering and war among humanity.
Quote from Ares in that episode, which would go well with this idea: "That's all you mortals are good for! To fight and fight and fight until there is nothing left but charred land and blood and bones, and to end it all and then start again with the next generation!"
