Emma Frost is a powerful and influential mutant telepath, most notoriously known as the White Queen of the Hellfire Club and occasional headmistress of the Xavier's School for Gifted Youngsters. Born to a rich Boston mercantile family, she parted ways with her family and built a financial empire with Frost International, ascending to a ruling position in the Inner Circle of the Hellfire Club. Demonstrating a particular interest in education, Frost ran the Massachusetts Academy, a preparatory school that secretly housed young mutants trained for her own interests, the Hellions. As an adversary of Charles Xavier's X-Men, Frost constantly used to clash with younger mutants she attempted to manipulate, such as Kitty Pryde, and members of the New Mutants and the New Warriors. However, the tragic death of her Hellions changed her heart, leading her to form a partnership with Xavier. Putting her love for teaching to good use, but never afraid to cross the line of the morally correct, she became the co-headmistress of Xavier's School, where she trained the latest generation of mutants, known as Generation X. As a survivor of the Genoshan genocide due to her new ability to transform her body into nigh-indestructible diamond, she became a inestimable member of the X-Men and has grown into a leader to the mutant community in general. Currently sitting on the Quiet Council of the mutant nation Krakoa, Frost remains a prominent figure in the thriving mutant society, influencing economic, cultural and diplomatic affairs between mutants and humans. She has rebranded the Hellfire Trading Company as a high-level transaction business to serve Krakoa's commercial interests, has become the host of the Hellfire Gala, and has assumed a role to financially and bureaucratically assist the recently reformed super-heroic X-Men.
