The X-Corps are a paramilitary group founded by Banshee with the purpose to police mutantkind and protect it from any threat, whether they originate from humanity or other mutants. The X-Corps should not be confused with the similarly named X-Corporation, or X-Corp for short, which is an extension of the X-Men with several offices all over the world.

Membership: Banshee, Multiple Man, Mastermind III, Avalanche, Radius II, Blob, Surge / Mystique, Sunpyre, Fever Pitch, M II, Jubilee II, Husk Associate: Abyss First appearance: Uncanny X-Men #401 Last appearance: Uncanny X-Men #406


  • During the Dream’s End crossover, Mystique and some members of her Brotherhood of Mutants III blew up the lab complex on Muir Island and Moira MacTaggert died of the injuries she received in the explosion. The rest of the Brotherhood tried to assassinate Senator Robert Kelly but the X-Men managed to stop them. At least Mystique and Mastermind III went into federal custody.
  • Hearing the news of his lover’s death, Banshee tried to drown his sorrow in alcohol. The disbanding of Generation X shortly after surely did not help. [Generation X #73, 75]
  • Radius had been a member of the reorganized Alpha Flight but, when the original members returned, he and several other newcomers were downgraded to Beta status. [Wolverine (2nd series) #142]
  • Sunpyre was among an emergency team assembled by Jean Grey when no other X-Men were available to deal with the threat of Genosha starting a third World War. After the crisis had passed, she turned down the offer to stay at Xavier’s mansion. [X-Men (2nd series) #112]


Uncanny X-Men #401: Standing at the grave of Moira MacTaggert, Banshee throws away his bottle of Scotch and decides that it’s time to move. Somewhat later, he has apparently started the X-Corps and Multiple Man, or actually half a dozen of him, break into a prison for super-villains and retrieve Mastermind III from the device that trapped her in a virtual reality. They also open Mystique’s cell but find it empty. Again some time later, a fleet of helicopters carries the Blob to the X-Corps building near Paris. He is escorted to Banshee’s office by Radius and Avalanche, who refuses to talk to his old pal. Inside the office, the Blob demands to know what’s going on but Banshee knocks him out with a sonic scream.
Uncanny X-Men #402: Curious about the new group, the X-Men visit the X-Corps building. Banshee openly welcomes them and shows them around and, although they admire the discipline and the vast technology at the X-Corps’ disposal, they think it looks too much like a military operation. Suddenly, an alarm goes off, as two mutants are registered battling each other in Berlin. Banshee sends his operatives to deal with the situation. Avalanche, Surge and the Blob quickly defeat the battling Abyss and Fever Pitch and also deal with a some members of the Acculturation Resistance Movement (A.R.M.), a local mutant hating militia. The X-Men are shocked that their old friend is working with well-known criminals and at the methods he uses to achieve his goals. In the X-Corps labs, Sunpyre studies the two captives and tells Banshee that they both have formidable powers but might be too violent to keep in line. Banshee, however, thinks otherwise and walks into a secret chamber, where Mastermind is strapped into a tank with cables and tubes connected to her body. He plans to use her illusion power to get both new arrivals under his control, just like he has already done with the Blob and possibly Avalanche before.
Uncanny X-Men #403: A young pyrokinetic mutant is almost killed by the anti-mutant militia A.R.M., but two of the X-men arrive in time to stop them. Just as the situation is calming, a group of X-Corps operatives arrives to take the boy with them, Fever Pitch already among them. Tempers flare but, with Multiple Man among the team, the X-Men know they are hopelessly outnumbered. Meanwhile, Nightcrawler and Banshee discuss their different approaches to mutant/human relations while Chamber, invited to join the X-Corps, discovers that several of his old teammates are in there too – M, Jubilee and Husk. However, they only joined to keep an eye on their old mentor and they have learned of something strange going on in the basement. Chamber investigates and finds Mastermind’s holding tank. Iceman at the same time witnesses the Blob behaving oddly, a sign of him being under some form of mental control. Surge secretly kills A.R.M. leader, Jakob Eisen, and several of his followers.
Uncanny X-Men #404: The news show a video tape of somebody posing as Jakob Eisen, leader of A.R.M., who claims that his organization exterminated X-Corps member Surge. Banshee sends M, Jubilee, Husk and Multiple Man to investigate but it’s a set-up. Although they have to fight an entire army of A.R.M. operatives, they are able to defeat them. Banshee finally snaps and uses his sonic power on one of the A.R.M. members, demanding to know Eisen’s location but Nightcrawler stops him in time and Sean finally comes to his senses. Meanwhile, Sunpyre is studying Abyss in the labs and is assassinated from behind. In the building’s basement, Chamber communicates with Mastermind on the astral plane. She tries to lock him out but underestimates him and Chamber witnesses a conversation between Mastermind and an unseen person, who has apparently infiltrated Banshee’s organization. Suddenly, Chamber is discovered and knocked out by Surge’s electricity blasts. Next to him are Blob, Avalanche and Fever Pitch, ready to take over the X-Corps headquarter.
Uncanny X-Men #405: While the others are still away, Radius is surprised by the Blob and Avalanche, who buries him beneath the ground. The villains escape with the entire fleet of X-Corps’ gunships. When Banshee and the loyal members return, they find that the X-Corps has been betrayed from within. Sunpyre is found dead in the lab and Abyss is in shock. The villains, especially Fever Pitch, cause mass destruction all over Paris to show the world the true face of mutant pride. It turns out that they also have some of the Multiple Men under mental control. Banshee and one of the loyal Multiple Man go to Mastermind’s chamber to shut her down but, just like Surge before, “Multiple Man” is actually Mystique in disguise and, from behind, she rams a knife into Banshee throat.
Uncanny X-Men #406: While Husk, Jubilee and Stacy X deal with the Blob, M helps some of the X-Men to retrieve the rogue Madrox duplicates and to detain Fever Pitch. Avalanche, however, shatters the Eiffel tower and then makes his getaway. In the complex, Mystique releases Mastermind from her holding tank as, with her help, she has been undermining Banshee’s X-Corps right from the start. They leave Banshee to bleed to death but, with his last will power, he drags himself to the lab and releases Abyss. As an alarm goes off, Mystique comes to check it out but gets sucked into Abyss‘ inner void. The boy is unable to control his power and Banshee is more than willing to let himself get soaked into the blackness too. However, Husk and Jubilee arrive in time to hold him back. After he is taken to a hospital, the X-Men and remaining X-Corps members mourn the dead Radius and Sunpyre.


  • Banshee is recovering in hospital. He might be permanently mute and powerless.
  • Multiple Man and M joined X-Corporation Paris, probably to make up for their involvement with X-Corps.
  • Off-panel, Husk seems to have accompanied the X-Men and has been living at the mansion ever since. In Uncanny X-Men #413, she evidently has been staying there for quite some time and she seems to be on the way to fully join the team.
  • Avalanche probably helped his pal Blob to escape from the authorities. In Weapon X #4, they had a brief run in with the Weapon X agents.
  • Fever Pitch might still be in custody.
  • Mystique, apparently, is not dead, though it is unclear what happens to her in Abyss’ void or how and where she will emerge from it.
  • The whereabouts of Jubilee, Abyss and Mastermind III are unknown.
