Selene is both a mutant and a powerful sorceress. She possesses a wide range of superhuman abilities, but it has never been clearly defined which of these are her actual mutant abilities and which are skills derived from magic or other sources.

Selene is a "psychic vampire" with the ability to sustain herself by psionically draining the life force of other human beings into herself. If she drains a person's entire life force, the victim dies and crumbles to dust in seconds. If Selene only drains the victim's life force partially, she achieves a measure of psychic control over her victim's mind, thereby subverting them to her will. Through unknown means Selene can also cause a human being to become a psychic vampire like herself, but be subordinate to Selene's own will. Selene's youthful appearance and vitality depends upon her absorbing the life forces of one or more people on a regular basis. This restores Selene to a youthful and healthy appearance when she has been injured, or when she over-exerts her other powers, and sustains her centuries-long life. A side effect of this process is that Selene remembers the life of anyone she absorbs.
