Waru is a complicated character with a tragic past, boiling with a thirst for vengeance just barely kept in check by a kind heart and artist's soul. He can control water, as you can see here.

I wanted to use the cardboard at the back of the legal pad at work to do some art when I finished the paper, and I discovered it takes markers rather well. I really like how this came out, though it has flaws. I would really appreciate critique on this one.
