Justice League: A Better World
Know spells cast by Circe:
Projective Animal Metamorphosis: Her most well-known and principle magical feat is, with a gesture, to turn objects and people alike into various sorts of animals, called Beastiamorphs. She has an especial preference for subjecting men to this transformation. In these forms, they are subject to Circe’s will and often in a tranquilized state, unable to resist her.
Matter Transmogrification: She can transform objects and beings into whatever form she desires.
Reality Alteration: Her sorcery allows her to manipulate reality to a degree.
Immortality: As the child of a Titan, she is granted ageless immortality, though she can apparently be physically harmed by a sufficiently strong attack.
Alter Minds: She can alter minds and control them utterly.
Magic Blasts: Can fire destructive magical energy blasts.
Magical Shields: Able to erect physical barriers of magical energy of great durability and strength.
Clairvoyance: Circe also seems to have limited clairvoyant potential, mostly demonstrating a mystical awareness of guests on her island and the presence of other immortals in her company. She was able to detect Hermes in an invisible state when he visited her.
Teleportation: Capable of tapping even cosmic energies, she can teleport between dimensions such as from Earth to Olympus.
Necromancy: (formerly) During her time in Hell, she gained the limited ability to manipulate the dead to do her bidding, but has not often demonstrated these abilities since her return to Earth. She is a sufficiently skilled necromancer that she was able to return Hippolyta from the realm of the dead.
Circe is a powerful crafter of the mystical arts and with the disappearing of other more powerful magical entities (both good and evil) she has become more. She knows that the Justice Lords are weaker in the magic department since they disabled their more powerful ally on the dark arts, Doctor Fate. Rumors are that she is using her resources to find more power and be able to confront the Justice Lords.
