The identity used by Emma Frost during her criminal days, the White Queen was a member of the Hellfire Club's Inner Circle. Frost occasionally still answers to this alias, but more often than not she now sticks to simply using her own name. Frost has recently reveiled that she is in contact with the current incarnation of the Hellfire Club, but whether or not she will return to her White Queen identity has yet to be seen.
