Alastor is a slim, dapper sinner demon with beige-colored skin, and usually has a broad smile full of sharp, yellow teeth. Alastor's eyes have dark-red sclera, bright-red irises and thin black pupils. His forearms and lower legs fade to dark grey, and he has red hoofed toes and red fingers. He sports a pinkish-red cropped, angled bob-cut with black tips at the ends and two large, black tipped tufts of hair extending from the top of his head, evoking the ears of a deer. He's 7 feet tall.
