Over forty years ago, Charles Xavier created an elite team of mutants and called them the X-Men. They helped fight for peace between humans and mutants respectively. Over the years, many mutants have joined the X-Men in their crusade for equality, and just as many have defected and joined their evil counterparts. Throughout the many X-Men stories that have been told, time-hopping mutants and devices have created alternate universes which introduced new X-Men teams, mutants, and has even changed the original backgrounds of characters we’ve grown to love.
Whether it began as a fight over moral differences, being brainwashed, or simply an evil version of their 616 counterparts, many X-Men have fought against their fellow teammates. Often, these fights have just lead to defeat, but occasionally the heroes we love were responsible for the devastating deaths of their fellow X-Men. Here is the list of 20 Times X-Men Killed Other X-Men.
20. Dark Cyclops Kills Professor X
In Avengers vs The X-Men, the Phoenix Force, an immortal and indestructible cosmic entity which had previously corrupted and destroyed its hosts, comes back to earth searching for a host in the form of Hope Summers. The Avengers and X-Men have differing opinions on how to handle the situation, which eventually leads to a war between the two factions. During a confrontation with the Avengers, Cyclops becomes one of the hosts for the Phoenix Force– Dark Cyclops.
After a very long and drawn out war between X-Men and the Avengers, Cyclops’ mentor Professor Xavier sides with the Avengers as he knows that he needs to stop the Phoenix Force. Xavier attempts to appeal to Cyclops’ conscience and telepathically guilt him into stopping his destruction. When this appeal to Cyclops’ conscience does not work, Xavier aids the Avenges in defeating Cyclops. Xavier confronts Dark Cyclops and attempts to convince Cyclops to stop his endeavors one last time, before launching an attack on Dark Cyclops. Having none of it, Dark Cyclops blasts Xavier with fire, killing his mentor.
19. Wolverine kills The X-Men
The most devastating X-Men massacre by Wolverine occurs in the Old Man Logan series, where Logan unwittingly finds himself manipulated by Mysterio, the master of illusion.
At the start, Logan and Jubilee receive multiple distress calls from all over, when a blast knocks Jubilee out. Logan sees the combined forces of the major super-villains the X-Men have fought through the years. Wolverine fights and viciously kills all of these villains while searching for the other X-Men who have not yet come to his aid and, after stabbing Bullseye through the heart, he looks down and finds that he is holding Jubilee’s body. Mysterio introduces himself and reveals to Logan the bodies of his teammates.
Devastated by his actions and the deaths of his friends, Wolverine was so badly broken that he “kills himself” by laying his head on train tracks and allows himself to be hit by a train, vowing he will never use his claws to kill again.
18. Psylocke kills Angel
During Sam Humphries’ relaunch of Uncanny X-Force, Psylocke, and Angel joined the X-Force.

During this time, Angel’s Archangel power begins to reemerge, and Angel struggles to contain the Archangel’s power.
As the Archangel’s power overtakes Angel, the X-Force hurries to find a remedy and travel back to Earth-295 to locate the Seed of Life, which will counteract Angel’s power and save him from the Seed of Death. However, by the time they find the Seed of Life, the Archangel has completely consumed Angel. Archangel, who has risen to the full height of his power, plans to extinguish all the life on earth. Unable to stop the Archangel or to bring back the original Angel, Psylocke stabs Archangel with the Seed of Life, killing both the Angel and Archangel personas.
17. Wolverine kills Jean Grey
Wolverine is no stranger to death and mayhem. He has even acknowledged that one of the only things that he is good at is killing. As a character who has traveled through multiple universes and suffered from amnesia multiple times, it is unsurprising that Wolverine has been responsible for many X-Men deaths.
One of the more notable Wolverine kills happens in New X-Men. Magneto traps Wolverine and Jean in a metal asteroid hurtling toward the sun as he attempts to take over New York. Wolverine and Jean scramble to stop the asteroid from its collision course with the sun by ripping up wires and trying to re-route it. Their attempts are futile as they edge closer to the sun and Wolverine and Jean begin to feel the effects of the heat. Wolverine and Jean share several sweet moments as they work, but Jean succumbs to the heat and passes out.
Unable to watch Jean suffer, Wolverine tells Jean that he would die for her, but at this time all he could do was take her pain away as he stabs her in the stomach, his claws emerging from her back. Horrified and devastated at what he has done, he waits for the asteroid to hit the sun to take his pain away.

Dust proceeds to flay the skin off of Graymalkin and Anole and then suffocates Emma Frost on her way to finding Ink.
