Satana is the half-succubus daughter of the demon Marduk Kurios. She uses her many supernatural powers to feed on the souls of mortals.
Satana was recruited to join the Crimson Cowl’s Masters of Evil, intended to serve as a foil for Doctor Strange. Although her demonic powers proved challenging to Strange, the Sorcerer Supreme managed to subdue her as the Masters escaped. Strange banished her to a pocket dimension prison until such time as more earthly imprisonment became available.
