Molpe Peisinoe

He is a a genius inventor that no one knows much about, he is a siren who lives underwater in a hidden cave, he loves singing to the female humans to eat the humans he sees no good things about them, he has a powerful voice when he sings his victims down to the ocean, he also hates Oliver Wing very much for not seeing why humans are useless to them, he is cold, can be a yandere, he is stubborn, hard to talk too, loves inventing, a lot of interesting things, when he touch the water he grows fins like a marman but he is a monster version, he does go to the human world like this in his human form but only to get some things he need to build things, he thinks he is a lot better than everyone he has seen, he thinks Dr. Marshall is wasting his time with humans since he knows Dr. Marshall isn't human ether, he is rude sometimes,(he only likes girls sorry boys)(idk if I said he does eat humans well since sirens are known for that..)
