Appearance: A highly-attractive white-skinned woman with a horse's head and a red mane.
Powers: Teleporting in a blinding flash of light, the ability to pull mystical guns out of the air, shielding against any sort of unwilling control, plus various other demon-type powers and immunities. Also she knows martial arts. And all of her powers work better on beings who are supposed to be in an underworld.
