Lorna Dane is a mutant, born of an affair between her mother Suzanna and Magneto. Her mother's husband, Arnold, later learned of this affair and confronted his wife while he was flying her and Lorna on his plane. An argument erupted, upsetting the infant Lorna whose desperation to make her parents stop fighting caused an early manifestation of her immense magnetic abilities, which caused a magnetic pulse that destroyed the plane and killed her parents, as well as giving her hair its iconic green color. Lorna survived the crash and was found by her true father, Magneto, who had been drawn to the location by her magnetic pulse. Believing that she was not ready for her abilities or the life he could offer her, he had his associate Mastermind use his illusionary powers to re-write Lorna's memories of that day, leaving her to believe that her parents died in a plane crash when she was an infant. Lorna was raised by Arnold's sister and her husband, and grew up thinking that they are her real parents until she was informed of the truth when she was almost twenty years old - Lorna's foster parents had feared it would cause her extreme stress and trauma if they told her before.

Soon after, Mr. Sinister sent the incorporeal being Malice to bond with her...which lead to her possession and current situation.
