Lucifer is a slender-figured fallen angel who sports a close resemblance to his daughter, Charlie - having her white skin with rosy-cheeks, blonde hair with thin light coral streaks on the thicker, paler blonde highlights, and eyes with light yellow sclera and red pupils. He is shorter than his daughter, though not by a large amount.
Unlike Charlie, his mouth is full of sharp teeth, his hair is short-cut and has been slicked back with one tuft sticking out, his pupils are slit like a snake
