Kamek the Magikoopa is a practitioner of the dark arts. Drawing his power from an ancient Elder Blooper that lies dreaming at the bottom of the ocean, Kamek is an expert necromancer and alchemist. He controls an army of the undead, including the ghostly Boos, and the skeletal Dry Bones. He currently serves Bowser, but he is treacherous in nature, and some day he hopes to overthrow the Koopa King.
(I have had this lying around for a while, but I didn't upload it, because it really didn't come out like I wanted to at all. I wanted him to be threatening, and I think he came out too cartoony and too Harry Potter-ish. But since Super Mario Galaxy is coming out tommorow, and since I haven't put anything up in a long time, I decided to upload it.)
