Surprises like this are one of the big reasons why we love superhero comics, but looking at the history of the team and their enemies, many of these deaths were shocking. They came out of nowhere, and left readers gobsmacked. These ten X-Men deaths shocked everyone, their surprising nature making them legendary.
10) Fantomex

Fantomex isn’t the most popular X-character, but he has a rather vocal fandom. The character became a favorite of fans thanks to New X-Men and Uncanny X-Force, but he disappeared for a while before being brought back for Astonishing X-Men (Vol. 4). Fans were excited to see him again, especially in a book with Psylocke, but he played an extremely minor role in the team, and eventually gave up his body so that Xavier could come back to life in it. No one expected this death, and it was one of many bad decisions made over the course of this 18-issue mistake of a reboot.
9) Professor X

Professor X has died plenty of times over the years, and it’s almost always pretty shocking honestly. However, the most shocking of his deaths came in the underrated Avengers vs. X-Men. Xavier tried to talk sense into the X-Men after they kept following the Phoenix Five and then ended up helping the Avengers and X-Men in their final battle against Cyclops. And then Cyclops killed him. It was a moment that came out of nowhere, and led to several years of everyone hating Cyclops for it.
8) Captain Britain II

The Krakoa Era saw a new volume of Excalibur and a new role for the former Psylocke Elizabeth Braddock as Captain Britain. She was the star of the new volume of the book, and that’s why her death in “X of Swords” was so shocking. She was set against Isca the Unbeatable, and while it might seem like the end of the fight was assured, most fans figured she’d win somehow (mostly because she was a favorite of Tini Howard, who was one of the main ideators of the story). She was killed, smashed into a million pieces, and was unable to be resurrected with the Krakoan method, but she did get better later.
7) Cyclops

Cyclops is the greatest X-Man, and he has died several times over the years, with numerous deaths in the Krakoa Era. However, his most shocking death came after Secret Wars. The resulting Marvel reboot that came after the story opened up after a time skip and Cyclops was dead, killed after doing something “terrible” to the Inhumans and villainized by the world. We’d found out that he ended up secretly dying of Terrigen Mist-related M-Pox in Death of X, with Emma Frost using her powers to make everyone think he was killed by Black Bolt after leading mutants to destroy a Terrigen Mist cloud. Personally, I don’t know what’s more shocking: the fact that he died in a time skip out of nowhere after being the most important mutant on the planet or how bad the explanation was.
6) The X-Men in House of X #4

The Krakoa Era changed the X-Men for five years, and it kicked off with one of the most shocking X-Men (team) deaths ever. This came in House of X #4, when Cyclops, Jean Grey, Wolverine, M, Nightcrawler, Mystique, Archangel, and Husk went to the Orchis Forge to destroy it and end the threat of Nimrod. However, members started dying almost immediately, and as the issue went on, we’d watch each of them get killed, even though they ended up succeeding. This issue was wild, and fans were buzzing over how everything would work out with some of the most popular X-Men dead. Their death was a shock to the system, as was their resurrection in issue 5.
