The mutant nation of Krakoa is ending. The humans have found a way to defeat resurrection. Orchis has infiltrated everything. The dream Moira MacTaggert spent ten lifetimes building is collapsing, and the X-Men face a choice: fight for Krakoa knowing it cannot be saved, or find a way to preserve something worth saving from the wreckage. Fall of the House of X and Rise of the Powers of X run simultaneously, telling the same story from two perspectives.

Krakoa has solved resurrection. Death is no longer permanent for mutants. But if you can't die, what does faith mean? What does community mean? What does it mean to grieve? Kurt Wagner — Nightcrawler, the X-Men's most devout Christian — realizes that the mutant nation has everything except a soul. He sets out to build one. Si Spurrier's Way of X is the most philosophically ambitious book of the Krakoa era. Way of X #1–6 plus Legion of X #1–10, Spurrier's complete Nightcrawler-centred Krakoa story.

Reign of X Omnibus Vol. 1 is where Krakoa starts to feel less like a miracle and more like a political machine with cracks. The Quiet Council, resurrection protocols, X-Men public identity, Hellions chaos and the shadow of Moira all make the era more complicated. This is not just more Dawn of X; it is the stage where the mutant nation has power, bureaucracy and consequences.

Dawn of X Omnibus Vol. 2 deepens the Krakoa experiment after the initial shock has passed. The books begin turning worldbuilding into pressure: Mystique and the Quiet Council, mutant diplomacy, X-Force security failures, the magical border around Otherworld and the first signs that paradise has procedures, secrets and enemies. It is a continuation volume, but a useful one because it shows the new X-Men status quo becoming operational.

Dawn of X Omnibus Vol. 1 is the first real test of Krakoa as a publishing line rather than a single Hickman idea. Marauders, Excalibur, X-Force, New Mutants, Fallen Angels and X-Men all ask different questions about the mutant nation: diplomacy, magic, intelligence, youth culture and identity. The volume works because the line feels unstable and ambitious at the same time, like Marvel trying to make the X-office feel genuinely new again.

X-Men: Age of Krakoa by Kieron Gillen Omnibus — Immortal X-Men and A.X.E.: Judgment Day. The Quiet Council of Krakoa, the Progenitor Celestial judging all humanity, Sinister's schemes from within. X-Men: Age of Krakoa by Kieron Gillen collects Immortal X-Men #1-18 and A.X.E.: Judgment Day #1-6 — Gillen's focused statement on the Krakoa era. The Quiet Council of Krakoa — Magneto, Xavier, Mystique, Emma Frost, Exodus, Sinister — navigating mutant politics while the Progenitor Celestial (reactivated by the Eternals) judges all of humanity and finds it wanting. The most philosophical X-Men story since Morrison. Gillen at the peak of his powers, with Lucas Werneck on art.

X-Men by Gerry Duggan Omnibus — Cyclops leads the X-Men from the Treehouse in New York City during the Krakoa era. Sunfire, Rogue, Polaris. The Gameworld arc and Dr. Stasis as the new villain. X-Men by Gerry Duggan (issues #1-35 collected here) follows Cyclops leading the most traditional X-Men squad of the Krakoa era from their Manhattan Treehouse. Sunfire, Rogue, Polaris, Wolverine (Laura), Marvel Girl and Jean Grey as a flagship team. The Gameworld arc — an alien gambling circuit that bets on Earth's survival — and the introduction of Dr. Stasis as a new Sinister clone hunting mutants. Duggan's run is the most accessible entry point to the Krakoa era, balancing the epic with the character-driven.

X-Men by Al Ewing Omnibus — Synch, Wolverine (Laura), Polaris and Havok on Arakko. The Children of the Vault, Ewing's science-fiction complexity applied to mutantkind's post-Krakoa identity. X-Men by Al Ewing (issues #1-25 collected here) is one of the most intellectually ambitious X-Men runs of the Krakoa era. Synch, Wolverine (Laura Kinney), Polaris, Havok, Cyclops and Marvel Girl operate on Arakko (Mars), the mutant planet. The Children of the Vault — immortal post-human beings who evolved in an accelerated time-chamber — are the recurring antagonists. Ewing applies hard science-fiction concepts to the X-Men universe with Stefano Caselli and Pepe Larraz providing clean, dynamic art.

The Weapon X program created Wolverine — bonding adamantium to his skeleton, wiping his memories, turning a man into a weapon. Barry Windsor-Smith told that origin story in the legendary 1991 Marvel Comics Presents serial. Years later, the program returned: new directors, new victims, a new mandate. The Return collects both the foundational Windsor-Smith Weapon X story and the subsequent Weapon X series that expanded the mythology into a full ongoing conspiracy.

Cosmic X-Men Omnibus should sell as the mutant line looking upward: Shi'ar empire, Starjammers, Imperial Guard, Phoenix, Lilandra and the M'Kraan Crystal. This is where Claremont and Cockrum prove that the X-Men are not only a school or a persecuted minority metaphor, but a team whose family drama can scale to galactic politics. It is a curated cosmic shelf, not a generic X-Men greatest-hits volume.

The War of Kings is the culmination of years of Marvel cosmic storytelling. The Inhumans, led by Black Bolt, have taken control of the Kree Empire. The Shi'ar Empire, under the rule of the mutant Vulcan (Gabriel Summers, Cyclops's long-lost brother), is expanding aggressively. The collision of these two cosmic empires draws in the Guardians of the Galaxy, the Nova Corps and X-Men-adjacent characters across the Marvel cosmic universe.

The biggest Phoenix stories of the 21st century collected in one epic 1352-page omnibus. Grant Morrison's New X-Men delivers the devastating Here Comes Tomorrow arc, followed by the Phoenix: Endsong and Warsong limited series that explored the cosmic force's obsession with the Grey bloodline. The centerpiece is the complete Avengers vs. X-Men event, the seismic twelve-issue war that saw five X-Men possessed by the Phoenix Force and fundamentally changed the Marvel Universe. Then comes Dennis Hopeless' Jean Grey solo series, the Generations one-shot bridging past and present, and the triumphant Phoenix Resurrection that finally brought the real Jean Grey back to life. This omnibus tracks how Morrison, Jason Aaron and a generation of writers kept reinventing the Phoenix myth while honoring its emotional core.

Uncanny X-Men by Brian Michael Bendis Omnibus is the Cyclops outlaw-school half of the Bendis mutant era. After AvX, Scott Summers stops asking for permission and builds a revolutionary team with Emma Frost, Magneto, Magik and new mutants like Tempus and Goldballs. Chris Bachalo's jagged pages make the book feel like a movement under surveillance.

All-New X-Men by Brian Michael Bendis Omnibus — the original five X-Men travel from the past to confront who they became. Young Cyclops meets his future self, young Jean Grey faces the Phoenix's legacy. Stuart Immonen and David Marquez art.

Avengers vs. X-Men Omnibus — the Phoenix Force returns to Earth and splits the Marvel universe. Captain America vs. Cyclops, the Phoenix Five transform the world, Hope Summers as the chosen one. The event that changed everything. Avengers vs. X-Men #0-12 plus AVX: VS #1-6 and AvX Consequences #1-5 collected in the complete omnibus. The Phoenix Force returns to Earth targeting Hope Summers — Captain America demands she be handed over, Cyclops refuses. Twelve issues of Marvel's biggest superhero war: the Avengers fighting the Phoenix Five (Cyclops, Emma, Namor, Colossus, Magik with Phoenix power). Ends with Cyclops in prison and the mutant population beginning to rise again. The event that launched the All-New Marvel NOW era.

Uncanny X-Men by Kieron Gillen Omnibus is Cyclops at his most ideological: the Extinction Team is not a superhero roster but a deterrent. Emma Frost, Magneto, Namor, Colossus, Storm and Hope stand between mutantkind and extinction-level threats while Gillen turns Mister Sinister into a theatrical, genuinely modern menace. It is the sharpest bridge from Schism into Avengers vs. X-Men.

Uncanny X-Force by Rick Remender Omnibus — Wolverine's secret black-ops X-team targets threats before they happen. Archangel as Apocalypse's heir, the Age of Apocalypse revisited, the Brotherhood of Evil Mutants. Dark, central Marvel. Rick Remender's Uncanny X-Force ran for 35 issues (#1-35 plus point issues collected here) and is widely considered one of the greatest X-Men runs ever published. Wolverine, Archangel, Psylocke, Deadpool and Fantomex operate in secret to kill threats before they arise. The Dark Angel Saga (issues #8-18) is a masterclass in long-form superhero comics — Warren Worthington III fully becomes Apocalypse, and the X-Force must decide whether to kill their friend. Jerome Opeña's art is career-defining.

X-Men: The Messiah Trilogy Omnibus collects the complete Messiah Complex, Messiah War and Second Coming — Hope Summers, the first mutant born after M-Day, and the war for mutantkind's future. The complete Messiah Complex (2007), Messiah War (2009) and Second Coming (2010) collected in one volume — the trilogy that defined the post-Decimation X-Men. Hope Summers, the first mutant born after M-Day, is the key to mutantkind's survival. Cable takes her into the future to protect her. The X-Men and X-Force fight through time to bring her back. Second Coming ends with a death that reshapes the team forever. Over 1,200 pages of the highest-stakes X-Men storytelling of the 2000s.

X-Men: Decimation Omnibus is the aftermath volume where three words turn mutant history into a survival problem. After House of M, only a tiny population keeps its powers, Xavier's school becomes a guarded refuge, and the government's Sentinel protection feels uncomfortably close to imprisonment. It is a bridge volume, but a crucial one between M-Day and Messiah Complex.

The House of M reality — where Magneto rules and mutants are the dominant species — touches every corner of the Marvel Universe. Spider-Man is a celebrity. Captain America never went into the ice. The Hulk was sent off-planet. This companion omnibus collects the tie-in series that show what House of M's altered reality looked like for every major hero, providing story material that makes the main event's conclusion hit considerably harder.

Ultimate X-Men Omnibus Vol. 1 is the mutant franchise rebuilt for the early-2000s Ultimate line: sharper politics, younger characters and no decades of continuity protecting anyone. Mark Millar and Adam Kubert make Xavier's school feel like a dangerous experiment, with Wolverine, Magneto and Weapon X recast through a more paranoid post-9/11 superhero lens.

Ultimate X-Men Omnibus Vol. 2 is where the line becomes less pure Millar blockbuster and more character machine. Brian K. Vaughan brings warmth and structure after the harder Weapon X material, using Gambit, Longshot, Rogue and the wider Ultimate universe to test whether these versions can become more than edgy remixes of familiar mutants.

The third Claremont Wolverine omnibus covers the series' transition period as the Mutant Massacre and Fall of the Mutants events reshaped the X-Men landscape, requiring Wolverine's solo book to operate in direct response to seismic changes in the main X-Men line. Claremont used this period to deepen Logan's physical and psychological wounds from the Mutant Massacre, explore his complex feelings about the Xavier Institute's direction under Magneto, and introduce new supporting characters that would define the solo series through the Hama era that followed.

Wolverine & the X-Men by Jason Aaron Omnibus is the X-Men school book after Schism, with Logan trying to run a place for damaged mutant kids despite being the least obvious headmaster imaginable. Jason Aaron and Nick Bradshaw build the series around chaos, comedy, grief and responsibility. Its value is tone and cast: Quentin Quire, Kid Gladiator, Broo and the students make the Jean Grey School feel alive, absurd and emotionally risky.
