Mathias has short brown hair that often sticks up since and hazel eyes. When he grows up, he will not be terribly tall, only reaching five foot seven. Left to his own devices, he pays very little attention to the way he looks, although he does pay enough attention to do things like shower on a regular basis, brush his teeth- though that’s more of a health thing since he doesn’t want them rotting and falling out-and use deodorant. However, other than that, he tends to wear bright colors and patterns, though sometimes he puts on patterns that don’t match each other. Mathias refuses to wear anything that is white, brown, beige or gray. Black is all right but only when paired with something brighter, like orange, which is his favorite color.
