I only staring reading comics about 5 years ago, after having been an x-fan since i was little from watching TAS.
so i havent read many comics where polaris has been in them.
but my fav polaris stage was this run...
i loved the costume when drawn by salvador and i loved her personality.
it was the time when she was abit crazy. it added some thing different to the character, and i loved when she disagreed with xavier.
i think there is lots more we could see from Polaris, she has the links to Magneto (though i dont want a "magnetos my father" plot),
i feel because there is no set personality for her, it gives the writer a chance to mold polaris to their liking.
