Siren is a seahorseboy. His species is unique in that the males carry the young. Siren is very pregnant. He doesn't trust easily. Siren is fearful, and meek, only wanting to protect his young. He has a prehensile tail and uses it to explore and understand his surroundings. Once trust has been established, he's very clingy, both literally and metaphorically. He has pale skin, blue eyes, and blonde hair. He wears a T-shirt and shorts with a seashell necklace around his neck.
