Why: Beginning her comic-book life as "Marvel Girl" in Stan Lee and Jack Kirby's "X-Men" #1, Jean Grey's "token female" status became a footnote following the conclusion of the legendary Phoenix and Dark Phoenix Sagas, which saw the telepath/telekinetic assuming near-godlike powers before eventually killing herself. It's that turn from good-hearted mutant heroine to destructive force of nature - a woman who gets a taste of her own power and is ultimately destroyed by it - that makes Jean Grey such a compelling character, and while that particular storyline already played out in Brett Ratner's "X-Men: The Last Stand," that film's poor reputation among acolytes of the franchise suggests there's more than enough room to give it another go with a younger actress in an origin-style standalone movie. Hell, there's even a love-triangle element to be exploited for younger "Twi"-hard types, which of course begs the question: are you "Team Scott" or "Team Logan"?
