Emma Frost
Emma Grace Frost is a fictional character who appears in comic books published by Marvel Comics. The character first appeared in Uncanny X-Men #129 (January 1980), and was created by writer Chris Claremont and artist/co-writer John Byrne.
An urbane, mutant telepath with a well-noted dry wit initially known as the White Queen, Frost has evolved from one of the X-Men's most dangerous foes to one of its most central members.
The character placed #30 as Marvel's highest ranking female on Empire's Top 50 Greatest Comic Book Characters in 2008 and took 69th place on Wizard’s 200 Greatest Characters of All Time List in 2008, ranking ahead of other X-Men with more extensive histories. She was ranked fifth in Comics Buyer's Guide's 100 Sexiest Women in Comics list.
Actress January Jones portrays the character in the 2011 film X-Men: First Class.
