The Serpent Demon has long black hair that reached past her shoulders, yellow eyes with thin slitted pupils similar to a snake, a wide fanged mouth stretching from ear to ear, and vein-like patterns around her eyes. Her long tongue was forked at the end and she had sharp nails on her hands. Her upper torso had three violet lines alongside the oblique of her chest. The lower half of her body was that of a traditional snake, with an elongated legless body covered in brown scales.
