How many X-Men have died and who were they?

Answer 1

In the comic books, death has become a running joke. This is because most of the characters who die, will find themselves resurrected at some point in later printing, whether it be the next week or in fifteen years. Almost all of the major X-men characters have died or have appeared to die at one point or another. In just the comics, some of the biggest names who have died are Thunderbird, Jean Grey, Psylocke, Emma Frost, Professor X, Banshee, Vulcan, Sabretooth, Nightcrawler, and Cable. Be assured, there are many more. Be even more assured, some of these have died multiple times, and / or their deaths no longer count due to later retconning.

In the films, Cyclops, Professor X, Sebastian Shaw, Emma Frost, Banshee, Angel Salvadore, Azazel, Lady Deathstryke, and Darwin. However, with the recent revisions to the timeline, it's hard to determine what is going on with continuity, let alone who is still alive or dead.
