Deep is a 15 year old humanoid creature who is mainly part blue whale, sea snake, and anglerfish. He has light blue-green scales, short and messy black hair, fin-ears, three arms, three glowing blue eyes, and an  esca bulb. He has no legs and slithers with his serpentine fish tail. He wears a dingy shirt, leather sleeveless vest, fingerless gloves, a choker, and a holster with a small gun. He is curious, silly, bored, a little anxious, and a bit edgy. Sebastian is mostly the same but bigger.
