While there have been times when Kitty Pryde has been presumed dead, she has always managed to survive. These events include:
* "The Death of Jean Grey" (1980): Kitty was presumed dead after she was caught in an explosion in a fight against the Brood. However, she was later found to be alive.
* "The Dark Phoenix Saga" (1980): Kitty was almost killed by the Dark Phoenix, but she managed to escape.
* Other threats: Kitty has faced many other dangers, including a battle with Apocalypse and a battle with the Phalanx, and has managed to survive all of them.
It's important to note that in comics, characters often have a habit of "dying" and then coming back to life. This is a common trope in superhero comics, and Kitty Pryde is no exception.
If you are thinking of a specific story where Kitty Pryde is seemingly killed, please provide more context, and I can help you clarify if this is a temporary situation or a more permanent event.
