Jean

Jean Grey
Jean Grey is the third in line for leader, most of the men have a crush on her except for Cyclops and Wolverene, they're in love with her. She's dating Scott. She is Xavier's favourite Xmen. In the first one you get a hint that she likes Wolverene, but in the second one she seems more into Scott. So you don't really know who she likes the most. In the second Xmen Xmen United she does the hero thing and sacrifices herself to save the others.

Powers

The Pheonix
After Jeans death Cyclops leaves the Xmen and goes to take out his anger, after he lasers the lake a bit Jean rises out of the lake and kises him but as she does he starts desintagrating and she kills him. She then goes for Wolverene though he is happy that she's alive he didn't want to kiss her so instead she threw him through the door and she escapes. Then she teams with Magneeto and tries to destroy the Xmen, Wolverene is forced to kill her. The Pheonix can decintagrate people.
