Lady Demon was published by CHAOS! Comics in 2000.

When Lady Death, tired of the endless battle, embraces the darkness within, a demonic persona evolved, and Lady Demon is born. This demonic incarnation cast Purgatori out to Earth and became Lucifer's consort. This did not last however, as Marion's spirit contacted Lady Demon and Lady Death returned to her senses. Absorbing her mother's angelic powers, Lady Death returned to battle Lucifer, ultimately casting him through the gates of Heaven.
