The first ''X-Men Forever'' series was a 2001 6 issue mini series written by Fabian Nicieza. In a similar vein to a previous similarly named story starring Comicbook/TheAvengers, ''ComicBook/AvengersForever'', the series was a TimeTravel story involving the grouping of Jean Grey, Iceman, Mystique, Toad, and the Juggernaut. It addressed classic ComicBook/XMen themes while trying to fix some instances of ContinuitySnarl and [[PlotHole Plot Holes]] that were attached to certain characters and events over course of the X-Men history. [[JustForFun/IThoughtThatWas This is not that.]]

The next volume of ''X-Men Forever'' (2009-2011) was a Marvel Comics title written by Creator/ChrisClaremont set in an alternate reality similar in places to the 1990s era of the mainstream Marvel Universe. The title allowed Claremont to tell the story lines he had intended to tell within the pages of X-Men Vol. 2 before a dispute with Bob Harras forced him to depart Marvel for a brief period.

The title was intended to reflect the X-Men's journey through a more consequential and more grounded world, where characters not only die, but STAY dead, certain characters also go through new, even questionable, changes and never revert back to their status quo. Claremont insists that all changes are permanent. The series lasted only two years, relaunching with a second volume, before being cancelled due to low sales.

!!Examples of the Claremont series:
* AdaptationalVillainy: The Trask family. Original flavor Bolivar was a misguided scientist who helped defeat the original Sentinels when they turned on him. Here, his father worked with the Nazis and fled to Argentina when the war was over, with Bolivar and his daughter continuing the work.
* AlternateUniverse: The continuity remains more or less the same as the 1990s era of the Marvel Universe, with changes occurring only when an X-Man makes a life-changing decision (Peter Rasputin beginning a relationship with The Black Widow). Interestingly, recent 616 events are also covered and better explained or abruptly ended. (The dwindling Mutant population and Storm's marriage.) It's officially Earth-161 of the Marvel {{Multiverse}}.
* AnyoneCanDie: The series kicks off with the death of Wolverine, and later kills off [[spoiler:[[ComicBook/IronMan Tony Stark]], Beast, and ComicBook/BlackPanther.]]
* AsYouKnow: A rather impressive version where Cyclops does this to ''himself'' at one point, recapping the team's plan in full detail apparently for his own benefit.
* BackportedDevelopment: Despite supposedly diverging around 1993, publication-wise, the Dora Milaje and Everett Ross -- both introduced in 1998 -- make appearances.
* BodyHorror: Both played straight and inverted in the case of [[spoiler:Rogue and Nightcrawler, who essentially switch powers and appearances when they touch after Rogue's powers were amplified by Fabian Cortez.]]
* TheBusCameBack: As the series begins, Shadowcat and Nightcrawler have returned to the X-Men after being in ''Excalibur'' (where they stayed in regular continuity until the title ended).
* CallBack: When Rogue goes walkabout in vol 2, one of the reasons it's hard to track her is the X-Men's immunity to being detected by machines, given to them by Roma after they defeated the Adversary (a plot point forgotten after Claremont left) is still in effect.
* CanonDiscontinuity: At least as far as this title's internal canon is concerned, ''the entire publishing output of Marvel Comics after X-Men #3'' is this. Not just the X-titles. ''EVERYTHING,'' [[spoiler:judging by Tony Stark's demise.]]
* CanonForeigner: Siegfried Trask, daughter of Bolivar Trask, instead of Anya, who does not exist in this universe.
* CartwrightCurse: Jean Grey has a hard time keeping her boyfriends alive.
* CastFromLifespan: [[spoiler:The source of mutant's power is their life. Once the power runs out, they die. What's unclear is how the likes of the 5000 year old [[Characters/MarvelComicsApocalypse Apocalypse]], who explicitly has {{immortality}} as one of his powers, is supposed to fit into this. Though Moira [=McTaggert=] mentioning that Logan's and Sabertooth's healing factors replenish their lifespan provides a possible {{Handwave}}.]]
* CloneAngst:
** There is at least one Storm clone running around. It's either the Evil Storm or the Kid Storm. [[spoiler:Actually, it's Perfect Storm -- Kid Storm is the real deal, only with her psyche having been ripped from her and made into a sapient energy field. By the end of the series there were THREE Storms running around.]]
** There's also an evil(er) Sabretooth clone. He's leader of the Marauders, an entire team of cloned mutants.
** [[spoiler:And an evil clone of Wolverine.]]
** Seemingly averted completely with (the late) Madelyne Pryor. ''Nobody'' -- not even Sinister -- refers to her as ever being Jean Grey's clone.
* CuteMonsterGirl: Rogue after accidentally swapping her and Nightcrawler's powerset becomes a surprisingly cute female counterpart to Nightcrawler, blue skin, devil's tail, elfin ears, fangs, and all.
* DramaticIrony: Homo Superior are the flawed creation, not the next stage of evolution.
* DudeWheresMyRespect: At [[spoiler:Beast's]] funeral, they're given a stirring eulogy by the President of the United States which manages to avoid mentioning that he's a Mutant or an X-Man. Jean notes this is par for the course.
* FaceHeelTurn:
** Ororo is revealed as Logan's murderer. Later, Illyana Rasputin, upon the restoration of her demonic powers reveals her true loyalties lie with Count Belasco, and willfully remains evil even after Kitty briefly turns to the dark side and rejects it.
** [[spoiler:Mariko Yashida]] is the second leader of the Consortium, [[spoiler: having taken over essentially to vent her rage both for Wolverine's death and the fact that Wolverine was having an affair with Jean Grey.]]
* FakingTheDead: The entire team does it at the beginning of the second volume, making it look like the X-Mansion went up and took them with it, so they can investigate the Consortium.
* TheGhost: Madelyne Pryor and that she died is mentioned several times, but nothing at all is revealed about how it happened. Everyone seems to recall her in only a positive light though, and Cyclops shows he's determined to be a devoted father to their son due to failing her in ways not elaborated.
* GoodScarsEvilScars: Storm has a huge scar across her face and between her eyes as a result of Kitty slashing her in retaliation for Storm killing Logan.
* HandicappedBadass: Sabretooth can kick your ass blindfolded and with only one hand. In fact, he sort of has to.
* HeelFaceTurn: Sabretooth and Mystique join the X-Men.
* ItsBeenDone: Aspects of Claremont's most famous unused storyline, Wolverine being killed and later used as a sleeper assassin for an enemy, were inevitably used TWICE. Once for "The Twelve" crossover story, and again for the "Enemy of the State" storyline in Wolverine's own title. The "Mutant Burnout" storyline, designed to explain why the Mutant race does not expand in greater numbers, is a more grounded version of the reality warps Marvel used to diminish the Mutant population at the conclusion of ''ComicBook/HouseOfM''.
* KidnappedScientist: The Morlocks abduct Moira so she can cure their burnout, something she was already working on anyway.
* KilledOffForReal: The revolving door on mutant heaven has been shut - nobody to die in this series comes back.
* KudzuPlot: But of course. Chris Claremont has a reputation for these. However, this series isn't quite as bad about it and even pulls together some things he would've resolved if given the chance in his original run. However, with the series' cancellation, we have more Kudzu plot that will never be resolved. [[spoiler: We leave the series with Nathan being ferried to Mr. Sinister for purposes unknown, Nightcrawler is near-comatose after having tried to absorb Thor's power, and the secret to "Mutant Burnout" is still undisclosed.]]
* LastDisrespects: The ''Alpha'' one-shot that kick-starts the series begins with Nick Fury giving Charles his opinion on Magneto's death; "good riddance."
* MindOverManners: In the third issue of vol 2, Jean and Scott have a psychic conversation while Nick Fury is in the room. He points out this is pretty rude of them.
* NonIndicativeName: For a series where people die and stay dead, the "Forever" part of the title is ironic.
* PapaWolf: A rather twisted version; after he hears about Wolverine getting killed, Sabertooth comes to the X-Mansion in a murderous rage, seeking vengeance for his son's death.
* PlotArchaeology: Way back in the ''Magik'' limited series, the elderly Storm in Limbo with Illyana couldn't use her Mutant powers in her old age. Claremont revisits that plot-thread with an explanation as to the "whys".
* PowerCreepPowerSeep: Averted. Claremont was not a fan of the ridiculously-strong HealingFactor of Wolverine, who's shown having trouble healing from broken ribs. Similarly, Sabretooth is blinded and isn't sure his eyes will ever heal -- although in that case it's justified as being part of his succumbing to Mutant Burnout.
* PutOnABus:
** Claremont dismisses most of the existing student body that was active in the 1990s by having them be placed in secret sub-groups and never mentioned again.
** Psylocke, Colossus, Forge, Iceman and Archangel, who were all part of the team in the opening arc of ''X-Men'', are all gone as well.
** Professor X leaves Earth in the ''Giant-Size'' one-shot.
* PsychicRadar: In #7, Jean Grey and Professor X work together to maximize their psychic radar scope and power and get around the interference from a mountain range.
* ReallyGetsAround: Jean Grey. In LESS than twenty issues, she bounces from Scott and Logan to cock-teasing Hank [=McCoy=]. WHILE MOURNING LOGAN'S DEATH.
* Really700YearsOld: In this universe, even though his body is that of a young boy, Mister Sinister has still been around for the whole of the 20th Century and is still very much young-looking in the 21st.
* RelatedInTheAdaptation: This version of Sabretooth is Wolverine’s father.
* ShipTease: After Rogue has spent a night testing her new abilities in Spider-Man's company, she teasingly suggests kissing him to see how her original powers have been affected by her new state.
* SymbolicCastFadeout: The comic had a cast list showcase with the X-Men having their picture. When they are killed, they have a "dead" cross posted over their faces in the following issue and then are removed, and when Wolverine was killed off in the comic's second arc, his crossed-off picture remained in the cast list for the next six issues to hammer home that ''[[AnyoneCanDie yes]]'', he was Killed Off for Real.
* TakeThat: A metric ton of it. Claremont wasted no time in using his creative freedom to snipe established mainstream continuity, which resulted in established and current developments and mythologies being swept aside so WordOfGod can set the record straight on what SHOULD have happened. Cable was never Nathan Summers, Nathan never went into the future, Sabretooth is Wolverine's father, Mr. Sinister is really a child, and so on. A lot of it was what he ''would'' have done had he stayed on X-Men back in the day.
* TheseusShipParadox: Brought up regarding [[spoiler:Storm being split into three different figures; "Perfect Storm" is essentially a clone created by the Consortium, while the original Storm's body is regressed to an amnesiac teenager and her mind and essence is converted to an energy form that is provided with an artificial body by Tony Stark. The energy form eventually merges with the teen Storm to restore them both to adulthood, affirming that they are ''both'' Storm while Perfect Storm is the clone]].
* {{Xenafication}}: Kitty Pryde. Justified in that she's taking on Wolverine's personality traits [[spoiler:as well as a stolen claw]], and lampshaded non-humorously by her friends and family worrying about the darker turn her character's taking.
