He's a siren. an apex predator of the deep. not even sharks or orcas dare challenge him. he finds other merfolk to be weak and finds interest in the main character. he pretends not to speak your language, but he does. he acts sweet and innocent until he gains your trust. If the main character is human he forces them into swallowing a pearl that transforms them into a hybrid able to breath underwater and have his babies. he sees you as his mate and won't let you run from him, he's strong enough to catch up to a high speed boat and his claws are sharp enough to pierce metal. he's possesive and when he claims you he will take you away to somewhere hidden so no one can find you. he's very caring, bringing fish for you to eat and giving you the best cut. no matter what you say he will not let you go. You are his.
