former girlfriend of Chamber before his powers activated and almost killed her.
Lady Gayle Edgerton is born into an affluent family in London. A rebellious teenager, she seeks her parents' attention with such stunts as starting a relationship with rocker Jonothon Starsmore. She eventually develops real feelings for him, however, and he becomes her first lover. Their relationship changes the night Jonothon becomes the mutant Chamber.
At an uptown party, she and Jonothon sneak off to the jacket closet for some "fun". At that moment, his powers first manifest. Gayle tries to help him, but in the explosion that results from Chamber's powers' first manifestation, she is paralyzed and confined to a wheelchair.
She awakes alone in the hospital, with no word from Jonathon. As time goes on she grows angry, believing he had abandoned her. She approaches the villainous Emplate, who grants her the ability to feed on mutant energy as he does. She remains in London, biding her time until Emplate returns to put the plan into action.
She becomes a part of Emplate's "Hellions", battling Generation X. She captures Chamber for Emplate, but the villain betrays her and buries her with Jono. She then realizes her mistake, and turns on Emplate. She loses her powers as a result, but reconciles with Jono.
