ポラリス (X-メン)
In X-Men #177, it was revealed that Polaris had lost her powers on M-Day, but had avoided telling her teammates. When confronted by Valerie Cooper, who has knowledge of her power loss, Polaris claims that her power loss is psychological and she believes she is preventing herself from using them. Polaris eventually was forced by circumstance to accept that her powers were gone and admit the fact to the rest of the team - whereupon all the other members of her squad, except her would-be-paramours Iceman and Havok, revealed to her that they had already guessed it.
In the Ultimate Marvel continuity of Ultimate X-Men, Polaris is an attractive teenage mutant girl who is a member of the Academy of Tomorrow, a mutant peacekeeping squad led by Emma Frost. In this continuity, she is also the girlfriend of Havok but as a twist, she was also the ex-girlfriend of his brother Cyclops, whom Havok resents with a passion.
Polaris is framed for killing dozens of people with her powers during a rescue mission, and imprisoned in the Triskelion of the Ultimates with mutant terrorist Magneto. Magneto uses her to goad Havok into rescuing her, so that he can escape the maximum-security cell by swapping places with Mystique. In the end, Polaris' name is cleared, and she returns to the Academy of Tomorrow.
