Circe is the daughter of the magical Titan, Hecate. She finds amusement in cursing them into pigs, and different kinds of animals that have disabilities. According to the book "Illiad", Circe tortures sailors by imprisoning them on her island and turning them to pigs.
Circe is wicked and evil.
Circe, like Hecate, is a magical goddess and can control magic, thus meaning that she can cast any spell, for fun, or for torture.
Circe's official Greek name is Κιρκη.
