Abraxas is a demon that dwells in the Astral Plane. He is known for turning a witch's magic against them by reversing past casted spells. He is able to open portals between the astral plane and the Earth plane. He was able to steal the Book of Shadows from the Charmed Ones, and started reversing spells, summoning Jeremy Burns the Warlock, Nicholas, and the Woogyman and them all to attack the Charmed Ones. He can emit powerful force blasts. The Charmed Ones vanquished Abraxas by drawing him to a place of power and harnessing the energy of the equinox by reciting the words to the incantation to unbind their powers.
