Selene Gallio, The Black Queen, is a mutant and enemy of the X-Men. She is part of the Hellfire Club’s Inner Circle and claims to be immortal. A psychic vampire, she is able to drain the lives of others in order to live forever. She is in many ways the epitome of the legendary first woman, Lillith. But with the emergence in latter years of the White Queen, Emma Frost, as a positive force, Selene has sort of fallen by the wayside which is too bad. The potential for a mutant vampire is endless and good a strong storyline for Marvel to pursue.
