Wilbur is a human with light skin, black eyes, and brown hair. Before his creation L'manberg, he wore a white shirt, black jacket, black pants, and black shoes. After his resurrection, Wilbur wears a dark brown coat over a yellow sweater and a bloodied bandage on his left arm. He claims that it is the same trench coat he'd been wearing at the time of his death. His previously all-brown hair now has
white streaks running through the front of it, presumably as an aftereffect of his revival.
