Lucifer is a slender-figured humanoid fallen angel who sports has light ivory 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 irises. Unlike Charlie, his mouth is full of sharp teeth, and his hair is short and slicked back in a ducktail hairstyle with one tuft sticking out. His tongue is forked, his irises sometimes appear slitted like a snake's pupils, and his eyelids are light purple.
