Created by writer-editor Stan Lee and artist Jack Kirby, the series launched in September 1963, introducing in its first issue the original five X-Men (Angel, the Beast, Cyclops, Iceman, and Marvel Girl) and their teacher, Professor X, as well as their nemesis, the supervillain Magneto. Initially published bi-monthly, it became a monthly with issue #14 (November 1965). Lee's run lasted 19 issues, and featured X-Men battling villains such as Magneto's Brotherhood of Evil Mutants which included the Scarlet Witch and Quicksilver; the Sentinels giant robots programmed to destroy all mutants, and their creator Bolivar Trask; and Juggernaut, Xavier's stepbrother transformed by a mystical gem and seeking revenge on Xavier.
The series was placed firmly in the Marvel Universe, with guest appearances by Namor in #6 and the Avengers in #9. The jungle adventure hero Ka-Zar and the Savage Land were introduced in issue #10. Roy Thomas wrote the series from #20 (May 1966) to #44 (May 1968). Thomas and artist Werner Roth created the Banshee in #28 (Jan. 1967). The X-Men #45 (June 1968) featured a crossover with The Avengers #53 (June 1968). After brief runs by Gary Friedrich and Arnold Drake – the latter of which introduced the new X-Men Lorna Dane and Havok, and during which the series adopted a new logo designed by Jim Steranko – Thomas returned to the series with issue #55 and was joined by artist Neal Adams the following issue for an acclaimed run of stories. After a battle with the Hulk in issue #66 (March 1970), the title ceased publishing original material and featured reprints in issues #67 (Dec. 1970) through #93 (June 1975).
X-Men was relaunched in May 1975 with Giant-Size X-Men #1, by Len Wein and Dave Cockrum. The title featured a new, international, team consisting of Cyclops, Banshee, Sunfire and Wolverine, along with new characters Storm, Nightcrawler, Colossus and Thunderbird. The original plan was to continue Giant-Size X-Men as a quarterly, but instead original stories were printed in Uncanny, again initially bimonthly. Chris Claremont's first issue as writer, #94, had all the original X-Men (bar Cyclops) leave, along with Sunfire; Thunderbird was killed in #95. Moira MacTaggert, a human ally of the X-Men, and later to be established as a former fiancée of Xavier, debuted in #96. Marvel Girl became the Phoenix in issue #101. This was followed by the first Shi'ar space opera story. Cockrum was replaced as penciller by John Byrne as of #108. Byrne became co-plotter, and during his run the series became a monthly title again. For the remainder of the decade the X-Men fight enemies such as Stephen Lang and his Sentinels, Magneto, Banshee's cousin Black Tom and the Juggernaut, the Shi'ar Erik the Red and the Imperial Guard, Arcade, Wolverine's former colleagues, Canada's superhero team Alpha Flight, and MacTaggert's son Proteus. In 2010, Comics Bulletin ranked Claremont and Byrne's run on The X-Men second on its list of the "Top 10 1970s Marvels".
The "Dark Phoenix Saga" in 1980 led to a change in the line-up of the team, with the death of Phoenix (Jean Grey), and Cyclops leaving the team to mourn for her. Comics writers and historians Roy Thomas and Peter Sanderson observed that "'The Dark Phoenix Saga' is to Claremont and Byrne what 'the Galactus Trilogy' is to Stan Lee and Jack Kirby. It is a landmark in Marvel history, showcasing its creators' work at the height of their abilities." The storyline also saw the introduction of recurring antagonists the Hellfire Club, and its Inner Circle consisting of Sebastian Shaw, Emma Frost, Harry Leland, Donald Pierce, along with Mastermind, previously a member of Magneto's Brotherhood. The new teenage mutant Kitty Pryde was introduced in #129 (Jan. 1980) and joined the X-Men in #139. The Dazzler, a disco-singing, roller-skating mutant, was introduced in #130 (Feb. 1980), but did not join the team, instead headlining her own solo title.
A new Brotherhood of Evil Mutants, led by Mystique, was introduced in the "Days of Future Past" storyline (#141-#142, Jan–Feb 1981) in which a time-travelling Kitty Pryde tried to avert a dystopian future caused by the Brotherhood assassinating Presidential candidate Senator Robert Kelly. Byrne plotted the story wanting to depict the Sentinels as a genuine threat to the existence of the mutant race. He then left the series after #143, being replaced by a returning Cockrum, who in turn was succeeded by Paul Smith and John Romita Jr.
By the mid-1980s The Uncanny X-Men had become one of the best-selling American comic books, turning many of the writers and illustrators into industry stars and leading to numerous spin-offs and miniseries.
Magneto was gradually revealed to be more complex: #150 established that he was a survivor of the Holocaust, and in #161 it is shown that Magneto and Professor Xavier had known each other before Xavier had founded the X-Men. Rogue, a member of Mystique's Brotherhood, defected to the X-Men in #171 (July 1983). Mystique's Brotherhood changed sides and became the government-backed Freedom Force in #199. Their first action was to capture Magneto, who had begun associating with the X-Men during the "Secret Wars II" crossover. Magneto surrenders himself, but escapes after his trial is abandoned, he takes over the headmastership of the school after Xavier leaves for space in #200 (Dec. 1985).
The Morlocks, a group of disfigured mutants living underneath New York City, were introduced in #169 (May 1983). Storm became their leader in #170. She was de-powered accidentally by government forces aiming for Rogue, and met Forge, a mutant with the power of invention. After Storm left the team temporarily to return to her native Africa, Nightcrawler became field leader.
The character Rachel from the future dystopia presented in "Days of Future Past" had been shown to arrive in the present day in New Mutants #18, and then made appearances in Uncanny from #184 and was revealed to be Cyclops's daughter.
Claremont attempted to write Cyclops out of the series, by having him marry Madelyne Pryor in #175 (Nov. 1983); she gave birth to his son in #201 (Jan. 1986). The X-Factor series was launched two months later and featured the original five X-Men. This meant the resurrection of Jean Grey (performed by retcon, the character appearing from #100 having never really been her), and having Cyclops abandon his wife and child. Claremont strongly objected to the latter, and was hostile towards the title until Louise Simonson became writer.
Artist Arthur Adams began a long association with the team by drawing The Uncanny X-Men Annual #9 (1985) and would serve as the artist on several of the annuals in the next few years.
The end of 1986 saw the first crossover between X-Men titles, the "Mutant Massacre", which saw a large number of Morlocks killed by the Marauders, acting under orders from the mysterious Mister Sinister. The late 1980s saw several other cross-overs: 1988's "Fall of the Mutants" and 1989's "Inferno", which resolved the issue of Madelyne Pryor by revealing her to have been a clone of Jean Grey created by Sinister. The cast was shaken up, with the addition of Psylocke, Dazzler, Longshot and Havok, in early 1987; the first appearance of NPR-TV reporter Manoli Wetherell in #226 (1988); new teenage mutant Jubilee in 1989, Forge in #255 (1989), and Gambit in Uncanny X-Men Annual #14 (1990). The X-Men left their traditional residence in Westchester County, New York, and lived variously on Alcatraz, Muir Island and in the Australian outback. The "X-Tinction Agenda" crossover, in which the X-Men, X-Factor and the New Mutants fight against the Genoshan government for mutant rights, was published in the fall of 1990.
The title became twice-monthly from 1988 to 1990, and helped to launch the careers of artists Marc Silvestri and Jim Lee. In 1991 another X-Men title was launched, titled simply X-Men; both titles were now published monthly. Claremont wrote the first three issue of this series, in which the X-Factor and X-Men teams reunited with Professor Xavier at the school. Claremont left Marvel after disputes with Bob Harras and artist Jim Lee (of X-Men). Claremont's final issue of Uncanny was #279, during the "Muir Island Saga", which is set before those events.
After Claremont's run, the X-Men were divided into two color-coded squads, with a Blue team headlining the adjectiveless X-Men title, while the Gold team, consisting of Archangel, Colossus, Jean Grey, Iceman and Storm, appeared in Uncanny. This roster was later joined by Bishop, another refugee from the future. After Claremont's departure, Jim Lee continued as plotter, while John Byrne scripted from #281 to #286. Byrne was replaced as scripter from #286 by Scott Lobdell, who was fully credited as writer from #289. The "X-Cutioner's Song" crossover was released in the fall of 1992 and resulted in the outbreak of the Legacy virus, a mutant-specific plague which continued as a story element in X-Men comics until 2001.
Crossovers continued through the 1990s. The "Fatal Attractions" crossover of 1993 saw the X-Men battle Magneto again, and the "Phalanx Covenant" story of 1994 focused mostly on the techno-organic Phalanx. Uncanny briefly ceased publication during the "Age of Apocalypse" storyline in 1995, which dealt with an alternative present created by a time travelling assassin killing Xavier; it was replaced by Astonishing X-Men. Lobdell was writing X-Men as well from 1995.
Lobdell was replaced by Steven T. Seagle with issue #350 (Dec. 1997). He was replaced in turn with Alan Davis, as plotter, from issue #366 (Mar. 1999) to #380. Davis's run included "the Twelve" crossover from #370-#375, in which Apocalypse sought the only twelve mutants, which also ran in his X-Men title, again being treated as a biweekly publication. As part of the Revolution relaunch, Chris Claremont made a brief return from #381 (June 2000) to #389, at which point he transferred to the new X-Treme X-Men title, as Grant Morrison took over the X-Men vol. 2 and that became the flagship X-Men title. From 2001 Lobdell made a short return, and then Joe Casey and Chuck Austen wrote runs into 2004. The title became bimonthly from 2003 to 2004.
The X-Men: Reload reshuffle of titles in 2004 led to Claremont returning to Uncanny with issue #444. The stories addressed the new status quo established by Morrison. Claremont remained until #473. His final story was the "Death of the Greys" in 2006, as part of the "Decimation" storyline, where the vast majority of mutants had lost their powers. He was replaced by Ed Brubaker, who wrote a 12-part epic space opera story "The Rise and Fall of the Shi'ar Empire", as a follow-up to his miniseries X-Men: Deadly Genesis. After this the title led into the "Messiah Complex" crossover event, dealing with the first mutant birth since the Decimation.
Matt Fraction became co-author from #500, and sole author from #504. The entire X-Men team relocated to San Francisco – firstly to the city, and then, after the "Utopia" crossover with Dark Avengers, to an island named Utopia in San Francisco Bay. The Nation X storyline focused on the return of the re-powered Magneto, and him coming to Utopia. The Second Coming crossover saw the return of Hope Summers, the baby from the "Messiah Complex" arc, to the present day, as a young adult; and the emergence of the "Five Lights", the first new mutants to have arisen (apart from Hope) since the Decimation. Nightcrawler was killed during this storyline and Beast left in protest after his discovery of Cyclops's secret death squad X-Force.
Kieron Gillen took over co-authorship of the series with #531, and became sole writer from #534.1.
The original series ended with #544 and relaunched as a new volume after the events of the X-Men: Schism miniseries, wherein half the X-Men, led by Wolverine, returned to New York, to found a new school. The new volume featured the Extinction Team, containing members of the X-Men whom Cyclops had retained to deal with potential threats to the mutant race's survival. Gillen's run led into and crossovered with the Avengers vs. X-Men event and finished with issue #20 in October 2012. The volume ended with Cyclops, who had become increasingly hardline during Gillen's run, in prison for his actions during that event. Gillen wrote a five-part epilogue, AvX: Consequences.
As part of Marvel NOW!, a new volume of Uncanny X-Men was launched in February 2013 with an April 2013 cover date, written by Brian Michael Bendis, who is also writing another X-Men title, All-New X-Men, and drawn by Chris Bachalo. It features Cyclops and remnants of his Extinction Team after the events of the first All-New X-Men story arc.
As part of All-New, All-Different Marvel, Uncanny X-Men was relaunched, written by Cullen Bunn with art by Greg Land. The relaunched Uncanny X-Men team features Magneto leading Psylocke, Archangel, M, Mystique, Fantomex and Sabretooth while a different team led by Storm will be called the Extraordinary X-Men. Cyclops's fate after Battleworld is shown to us in the Death of X miniseries. (Cyclops was exposed to the Terrigen Mist and died from M-Pox.).
The tagline for the relaunched series is "Bigger threats require more threatening X-Men", and is considered to be a continuation of Bunn's previous work on the Magneto solo series. The series will deal with threats that arise as a result of a new, more dangerous world post-Secret Wars. Summing up the team, Bunn states "They're upholding Xavier's dream, but they have no right to do so.".
Like many comic book series, Uncanny X-Men had an associated double-sized annual series, once in both 1970 and 1971, then regularly from 1979 to 2001. A second series of Uncanny X-Men Annual began in 2006 as volume 2, issue #1.
Cyclops, Magneto, Magik, and Emma Frost, who only have a fraction of their previous powers, have taken up a revolutionary, and sometimes violent course to promote mutant rights, and started up a new school for newly powered mutants, the New Charles Xavier School for the Gifted in an abandoned Weapon X bunker somewhere in Canada. Currently with only two students, healer Triage and mimicker Benjamin Deeds, Cyclops goes to Wolverine's school for mutants to recruit any new students. Only the Stepford Cuckoos and time-displaced Angel from the original X-Men join him. They go to San Diego to recruit Fabio Medina, aka Goldballs, who just manifested his powers and is being tracked by Sentinels. They then travel to Australia to recruit time controlling mutant Tempus only to scuffle with The Avengers. Tempus creates a time bubble that freezes the Avengers. It turns out that Magneto has been working with SHIELD and notifying them of the X-Men's movements. Cyclops discovers this, but Magneto claims that it as to cause internal disruption within SHIELD. As the team escapes they are pulled into Limbo by Magik.
The demon Dormammu has made a move to control Limbo from Magik. Cyclops and Magneto try to fight of the hordes of demons, but they are too depowered. The rest of the team have little or no battle experience and cower until the Stepford Cuckoos brainwash away their fears. Magik powers into her demonic form Darkchylde and collapses Limbo into herself and traps Dormammu and frees the X-Men. She then teleports into the past and trains with pre-Avengers Dr. Strange. Cyclops realizes how close of a call that was, so he begins training the X-Men. Fabio decides he wants to quit the X-Men, so he is returned to San Diego. Magik returns him, but then he is apprehended by newly appointed Mutant Liaison for SHIELD, Dazzler.
The X-Men return to save Fabio and with the help of new mechanical manipulating member, David Bond, aka Hijack briefly take control of the SHIELD Helicarrier. Later Dazzler is kidnapped and replaced by Mystique, who will try to use Dazzlers clout with SHIELD for her personal benefit. Cycplos is shocked to learn that many humans are actually taking his side and don't believe the propaganda from SHIELD about him, so he and the team travel to a pro-mutant human rally to thank them. It turns out a new indestructible Sentinel that learns and adapts to mutant powers. Hijack and Magneto cannot control it, but the Stepfords are somehow able to read its mind, proving that it may be sentient. Magneto is able to stop it by moving millions of tiny metal shards through the robot, but then it is teleported back to its mysterious owner.
A team of X-Men travel from the future to warn of great dangers. The Uncanny X-Men, the time displaced original X-Men, and Wolverine's X-Men need to set aside their differences and cooperate. See X-Men: Battle of the Atom.
Cyclops is getting frustrated with the lack of progress for Benjamin Deeds and considers him a liability in the field. Emma Frost helps him unlock another level of his powers: the power of persuasion. By partially mimicking people he lowers their defenses and gets them to do what ever he asks. Emma tasks him with delivering a message to SHIELD HQ—Stop sending sentinels or we will go to war.
The girls on the X-Men team decide that they need a girls night out and to do some shopping. They all travel to downtown Paris, but are interrupted by terrigen mist cocoon opening with a new Inhuman. AIM comes and kidnaps the new Inhuman.The team then sends all the younger members to Tabula Rasa for on the job training. The team is able to survive, but David Bond brings a cell phone with him that allows SHIELD to track them down. Magik helps them egress, but Cyclops is furious and kicks Hijack off the team. Kitty Pryde and the All-New X-Men are invited to Cyclops' New Charles Xavier School for the Gifted since they don't feel comfortable in Westchester, but not before almost mind melting Cyclops by phasing her fist into his skull.
Magneto travels to Madripor and is shocked to learn that Mystique is impersonating Dazzler and working with Silver Samurai, The Blob, and Sabertooth in selling Mutant Growth Hormone, which gives humans mutant powers and enhances mutant powers, but is extremely addictive. He attacks them and barely escapes.
The team travel to Chicago to investigate a mutant disturbance and are attacked by the new sentinels, that have adapted to all their powers, except Magik's sorcery, which she just recently learned under the tutelage of Dr. strange. Cyclops thinks SHIELD is behind these mutants and declares war on SHIELD and Maria Hill. He knows that the sentinels are tracking him via cerebro, so he travels to the only other person than Magneto who understands Cerebro—Hank McCoy at X-Mansion. Magik and Cyclops arrive only to have their powers hijacked and Agent Dazzler coming into arrest them, but Maria Hill comes and gives them a few minutes to investigate cerebro, despite Dazzler's protests. Then suddenly the SHIELD Helicarrier attacks the school and sets a nuclear countdown. Hank is able to surmise that Cyclops, Magik, Magneto, and Emma Frost are depowered and controlled by nano-technology sentinels and only one person has that technology--Beast from Age of Apocalypse. Cyclops and current Beast confront AOA Beast who is living in a life-support suit after experimenting on himself. His suit breaks and he dies.
Meanwhile, back at the X-Mansion, Firestar, Storm, and Iceman try to stop the Helicarrier, except the dozens of new indestructible sentinels come that have all adapted to the X-Men's powers. Unbeknownst, David Bond, the exiled X-man, has returned and used his power of control over electronic devices and vehicles to stop the nuclear launch and self-destruct the sentinels, which have not yet adapted to his powers since he was kicked off the team during the previous battle. Magneto was unavailable, sin he was in Madripor, following The Blob to the real Dazzler, who has been in a drug induced coma and Mystique has been using her blood to create Mutant Growth Hormone. Magneto frees and brings her to Maria Hill to prove she wasn't involved with the Helicarrier incident. Dazzler decides she doesn't want to work for SHIELD and joins the X-Men. She has a brief mental break down and cuts her hair and takes on a goth-like appearance.
The Uncanny X-Men are summoned back to the X-Mansion after Jessica Walters receives the last will and testament of Charles Xavier. He recorded his dying wishes on a Shi'ar projection device. He married Mystique before hsi death and before he announced his inheritor he wanted Scott and Wolverine to investigate a mutant named Michael Malloy, who he brainwashed and depowered as a young boy because he feared the child's powers.
SHIELD has made contact with a new plus-Omega level mutant named Matthew Malloy in Newberry, SC. The mutant has unlimited power over time, the mind, and psychics. He took out a SHIELD SWAT team with a flick of a finger. SHIELD asks Exodus and Headlok to psychically stop the mutant, but they are both killed. Meanwhile, back at Westchester, the X-Men are having difficulty understanding Xavier's action. Xavier also promised a future where all mutants live in peace and train to protect humans, but he has been brainwashing Malloy and preventing him from using his powers. He, Rachel Grey and Wolverine agree to confront and reason with the mutant, as per Xavier's wishes. They are intercepted by SHIELD who advise against confronting, so Rachel Grey uses a physic projection of Xavier, that Malloy sees through and then destroys the ruse and destroys the helicarrier. Luckily all the SHIELD agents have emergency bubbles that save them and the X-Men are teleported away.
Cyclops has another idea and asks Magik to teleport him and Malloy to Devils Tower to recruit him for the mutant revolution. Even Magneto sees the danger and tries to stop him, but is teleported away by Malloy. Magik tries to use the Eye of Agamotto from Dr. Strange to reveal Malloys true self, but the SHIELD shoots rockets at the three of them—killing them. Malloy is able to resurrect himself, but cannot help Magik or Cyclops. He them teleports to the Jean Grey School hoping that he can become a student, but Emma Frost is upset that Cyclops was killed and attacks Malloy. She is accidentally killed by Malloy's immense power.
A Dead man's switch activated a pre-recorded message when the three professors died and tells the students at the New Xavier School to go to a separate bunker and board a plane to the Jean Grey School. Eva Bell, who is it uncovered earlier has feelings for Cyclops, decides to use her time traveling powers to meet with Charles Xavier before he started the X-Men and warn him of the future danger he created with brainwashing Michael Malloy. Eva and Xavier then travel and Xavier prevents Malloys parents from ever meeting. Xavier understands that something serious needs to be done to prevent Cyclops from starting a mutant revolution, so he changes his will. Because Malloy never existed, nobody ever died and time is reset back to the reading of the Last Will and Testament. Eva Bell is the only one aware of the time shift, but she lets Cyclops know of what she did and warns if he ever tries to do something reckless like that again she'll go back in time and prevent Cyclops form being born. The Will stipulates that Xavier left the entire school and property to the current Scott Summers. Scott is shocked by this and racked with guilt, so he gives his inheritance to Storm. He also decides to close the New Xavier School and asks Storm if she will accept all his students, since he's giving up his Mutant Revolution.
Cyclops is alone at his school and his brother Havok came to visit him the New Xavier School after quitting the Uncanny Avengers. Dazzler comes up with a plan with Maria Hill to capture Mystique, but only under the condition that they erase all records against the students and professors of the New Xavier School. Maria only agrees to the students' records. The Dazzler and the Uncanny X-Men students use the Stepford Hive mind to brainwash Mystique and capture her, who has been posing as a Bollywood star. The students at first don't report immediately to the Jean Grey School, but instead use the X-Jet to go battle on their own. They form their own team called "The Squad."
Goldballs eventually becomes an Internet sensation and is featured on the Tonight Show. At first they do well, but eventually things get out of hand when an anti-mutant mob attacks them and police almost arrest them. They report the next day to the Jean Grey School for proper training. Younger Bobby Drake confronts the older Bobby Drake about secretly being a homosexual. He admits that he didn't want to be discriminated for being a mutant and a homosexual, and was too busy being an X-Man to explore his sexuality. He decides to stop hiding it from everybody.
Jean Grey decides that the All-New X-Men should go on a hiatus. Young Hank McCoy is upset, but she catches up to him and expresses that she still has feelings for him and they share a kiss. Magik and Emma Frost track down Colossus and brother and sister reconcile. All the current X-Men then give Hank McCoy an intervention. They are concerned that his taking too many liberties and justifying the ends for the means. Beast is upset and feels confronted and storms out. Suddenly an alert goes off in Washington DC and all the X-Men teams and students teleport to hear a speech from Scott Summers who announces the end of his Mutant Revolution. The volume ends with Beast packing his bags as he leaves the school, but is confronted by an older Eva Bell who tells him ominously, "What do you do with what happened today?".
The comic book starts in Detroit, Michigan, where Magneto stops a convoy of trucks owned by Someday Enterprises, a company which mutants scared of the terrigen mist can pay to be put to sleep and stored until the world is safe for them. Magneto, disgusting by the choices made by these mutants, threatens the men but when they shoot at him he defeats them with ease, accompanied by Sabretooth, Monet St. Croix, and Psylocke. Towards the end of this battle Magneto tires, having pushed himself too far after being brought back to life. One of the Someday Enterprises trucks drives away but Psylocke uses her psychic powers to control the blank slate Archangel into chasing it down. Magneto then removes the suspended animation chambers from the trucks and releases the mutants. The team realize somebody is injured and finds a stasis tube has been pierced with shrapnel, stabbing the mutant inside. One of the mutants is revealed to be a healer and heals the dying mutant, talking about how he paid all his money to just dream until the horror of the mists had passed. Magneto is unsympathetic and gives a speech about how their species is at a crossroads and he needs to help, warning that if he discovers the healer goes back to Someday, Magneto will treat him as an enemy to Mutantkind.
The healer released from his voluntary suspended animation wanders the city, finding a child and his sick mother in an underground car park. He heals the mother but is then instantly killed by the Dark Riders who believe those with the ability to heal are unnatural, due to being against the Darwinian theories of evolution and survival of the fittest as they can heal people who the Dark Riders view as too weak to be allowed to survive.
In San Francisco Mystique is undercover at Someday Enterprises but is discovered and has to fight her way out after just two weeks. Fantomex is also working with Mystique and the HellFire Club on uncovering the mystery behind Someday. Psylocke, using a portable Cerebro, realizes that the Dark Riders are killing mutants with healing powers, so they split up the team to track Elixer, Triage, and Xorn. Sabertooth and M track Exiler to a religious convent in Cooper's Mountain, Vermont. The Dark Riders kill the convent members and Elixer goes out to revive them, but not realizing it was an ambush, in which Gauntlet snipers him down. Magneto and Psylocke track Triage to a mutant hospital, where he is able to temporally cure mutants of M-Pox. Hurricane, Barrage, and HardDrive attack the hospital, but Magneto fends them off. M travels to Tibet where she meets Shen Xorn. He has secluded himself to a life of solitude and meditation and doesn't want the protection of the X-Men. Soon the Dark Riders attack his monastery, but he kills Barrage before the rest escape after not accepting his offer of tea Sabertooth, Psylocke, Arcangel and M track the Riders to a pyramid in Egypt, but it was a trap to split the team. The Riders teleport to Genosha and try to kill Triage. Spyne is able to strike a killing blow to Triage, but he can heal himself. Psynapse uses his power to prevent Triage from reviving, but Magneto kills him and Spyne. The rest of the X-Men are able to return in time to assist Magneto in finishing off the Riders. Magneto then ties the rest of the team to a bomb and blows up the Riders and the entire island of Genosha. Psylocke then brings Triage to X-Haven and Magneto tracks down Mystique and Fantomex for questioning.
Sabretooth and M meet with Calisto in the Morlock tunnels to investigate mutant kidnappings. It turns out M's brother Emplate is feeding on the Morlocks, some of the last surviving mutants. Monet tricks her brother into freeing the Morlocks and feeding on her, but then expels him and causes him to fade from existence. It turns out she was infected by his virus. Separately, Psylocke and Magneto travel to Green Ridge, Colorado and notice an Angel is attracting a crown of religious fanatics. It turns out Apocalypse's son, Genocide is harvesting Angel's wings and creating a clone army of archangels. Psylocke and Magneto are captured, but Psylocke easily escapes. She gets into a fight with Fantomex, who was sent by Magneto as back-up with Mystique, who herself freed Magneto. Psylocke in a panic calls for Archangel, who then controls the clone army and destroys the town. It turns out that Magneto found the Archangel's mindless body in a barn several months ago and Angel explains that they are two parts of the same being, so they combine into a new persona that has sworn off violence.Timeline
This is an article about the comic book, and thus the publication history, not the in-continuity history. As such, the above reflects the team roster for the book at time of publication. Similarly, this article only reflects the team roster for the X-Men team whose home is this publication.
Professor X is the Headmaster of Xavier's School for Gifted Youngsters and mentor to the X-Men, but he is rarely (if ever) a member of the X-Men team. In his role as mentor he has typically been present in the book, but he has notable absences including issues #43–64 (dead, later retconned as preparing for the Z'Nox), #200–273 (with Lilandra Neramani in Shi'ar space; replaced as Headmaster by Magneto during most of this absence), #340–351 (in government custody after the Onslaught crisis), #379–386 (educating Cadre K in space), and #495–513 (rebuilding his mind in X-Men: Legacy).
Jean Grey was replaced by the Phoenix Force from issue #101 through #137. This was a retcon that was only revealed years later.
At many times the team roster has been the same as that appearing in X-Men (vol. 2), and during two periods the two books have even been treated by their writer as a single bi-weekly title (issues #289–350 by Scott Lobdell and issues #366–380 by Alan Davis).
During issues #370–372 Wolverine was replaced by a Skrull infiltrator, leading to "The Shattering"/"The Twelve" storylines, and the Astonishing X-Men (vol. 2) limited series.
After moving to San Francisco, many other mutants continually appear as background characters or allies, but apart from during crossovers they are rarely considered part of the team roster. Characters featured include former X-Men such as Iceman and Hepzibah; New X-Men students such as Rockslide, Surge, and Hellion; Cannonball's New Mutants squad; and other mutants such as Toad, Frenzy, Diamond Lil, and Meld.
After the series was relaunched as Uncanny X-Men #1, it featured Cyclops's "Extinction Team", composed of himself, Emma Frost, Namor, Magneto, Storm, Hope Summers, Colossus, Danger and Magik; Psylocke was briefly a member of this team while Emma was injured.
Until 2011, Uncanny X-Men remained Marvel Comics' only Silver Age title to retain its consecutive issue numbering since its conception, even during the early 1970s reprint hiatus. The Amazing Spider-Man, The Avengers, Fantastic Four and other legacy titles have all, at one time or another, restarted their numbering at #1, though all later returned to their original numbering. The final issue to be published under the original numbering was #544, published in October 2011 with a December 2011 cover date, which was followed by a new #1 the following month. In 2015, Marvel released Uncanny X-Men #600, following Vol. 3 #35, as a conclusion to the Brian Michael Bendis' run on both "All New X-Men" and Vol. 3.
From issue #1 through #93 the indicia title was The X-Men. After the relaunch with issue #94, and up to #138, the article The was dropped from the indicia title, making it X-Men, but the article was added back in issues #139 to #141.
The title The Uncanny X-Men was first used in the issue #95 title block following the "Stan Lee Presents:" tagline, though the title did not appear on the covers or indicia titles yet. Covers begin displaying this title in #114. Beginning with issue #142, and up to #407, the indicia title was finally changed to The Uncanny X-Men. Issue #408 was the first to use the indicia title Uncanny X-Men.
A separate series, titled simply X-Men, launched with an October 1991 cover date.
