Theo is a very attractive young man who has tan skin, blue-gray eyes, and light brown hair that he wears tousled with gel. He has also been seen with some stubble on occasion. He is on the shorter end of average height with a lean, athletic build. Theodore Karl "Theo" Raeken was the first Chimera created by the Dread Doctors who managed to successfully complete his transformation into a Werewolf/Werecoyote without rejection. Theo eventually became a trusted ally of the McCall Pack.
