Jean Grey was a founding and loyal member of the X-Men, and a devoted girlfriend to Cyclops. But that all changed when the evil mutant Mastermind began to play with her mind, making her think she's really a Victorian aristocrat. Suddenly Jean was joining the Hellfire Club, helping capture the X-Men and wearing her lingerie in public.
The Black Queen Jean Grey is pretty well-known to comic-book reading males. Not for being part of the classic Dark Phoenix Saga, but for the lingerie.
