How did kitty pride die on x men?

Answer 1

There are loads of ways she can die.

If she is not phasing, she can suffer harm just like anyone else. (example: A sniper bullet from a distance.)

Since she is unable to breathe while "inside" an object, she can only continuously phase through solid objects (as when she travels underground) as long as she can hold her breath. If she were to fall unconscious (due to not breathing) and phase back in while in a solid object, she would die.

If she lives long enough, she WILL die... of old age.

In the end of Astonishing X-Men Vol 4: Unstoppable, she drifted off into space in a giant missile, she was inside it to save the world, and we don't know if she's dead.

Answer 2

Kitty Pryde apparently died when she phased a gigantic magnetic bullet through the Earth, but she really just remained phased and survived the ordeal. She has since returned in the X-Men.

Answer 3

She "died" during the Phoenix Saga and Dark Phoenix sagas.

Answer 4

wolverine killed her

Answer 5

Jean Grey kills him
