In Darksiders, you play as War, one of the four horsemen of the apocalypse. The other three, though, you never see them. They're away, at a volleyball tournament. If they were around, though, this is what they'd look like.
Vigil's Joe Madureira originally designed all four horsemen. He of course took some liberties; instead of War, Pestilence, Famine and Death, his horsemen are War, Strife, Fury and Death. And instead of being horsemen, there are three horsemen and one horselady.
Here are those other three. I didn't like the designs in Darksiders, but I must say, I'm digging the one here for Death. Why? Because he looks just like Casey Jones...
