The Lamia was once the beautiful Queen Lamia of Libya. Because of cruelty she was turned into a creature with the head and breasts of a woman and the body of a scaly goat. She is the fastest runner in the world, and is immortal. The Lamia delights in luring men to her and then tearing them to pieces. She also likes to steal children and eat them.
Another type of Lamia has the top half and head of a beautiful woman and the bottom half of a serpent.
