Jean Grey is a central character from the X-Men comics published by Marvel Comics. She has been known under the aliases of Marvel Girl, Phoenix, and Dark Phoenix. Jean Grey is a mutant born with telepathic and telekinetic powers. She is best known for her relationship with Cyclops (Scott Summers), but has also hooked up with Wolverine once or twice.
Famke Janssen portrayed Jean in the X-Men films. I think she did a good job and was really sexy. X3 sucked tho.
Here is some of my favourite pictures of her from over DeviantArt. Check them out and show them love.
