Emma Frost was a former member of the villainous group The Inner Circle. Emma later left the group. During Jean Grey'srampage due to losing control of the Phoenix Force, Cyclops spotted an astral projection of Emma Frost behind her, leading him to believe that Emma was manipulating Jean.
Emma was found by the X-Men unconscious in a laboratory in Japan. When confronted about her role in Jean's death, Emma denied this and blamed Mastermind for framing her using his illusionary powers. She then joined the X-Men.
