The Ultimate relaunch of the foundational Marvel team with a teenage genius Reed Richards, a college Johnny Storm, a young scientist Sue Storm and a Ben Grimm as his childhood best friend. Adam Kubert on absolute form: one of the best Marvel cartoonists of the 2000s. Co-scripted with Brian Michael Bendis.

Closing of the historic Claremont-Lee collaboration. After editorial differences over creative direction, Claremont left the X-Men after 16 years of uninterrupted writing — the longest continuous run on a superhero title in history. Jim Lee briefly took over the script before leaving to found Image Comics alongside Todd McFarlane and others. A moment of historic transition for Marvel and for American comics that changed the industry forever.

John Byrne joins Claremont on art and together they create some of the most important stories ever written at Marvel: Days of Future Past and the Dark Phoenix Saga. Jean Grey, possessed by the cosmic entity Phoenix, becomes the greatest threat in the universe and sacrifices her life to save the X-Men. Absolute must-read.

Start of the longest and most acclaimed run ever written about the X-Men: 16 uninterrupted years of Chris Claremont. With Dave Cockrum visually redesigning the team, Storm, Nightcrawler, Colossus and Wolverine are introduced and consolidated as the new X-Men. This volume includes the first appearances and development of characters who would define Marvel for decades. Absolute starting point of the modern mutant universe and required reading for any serious Marvel collector.

Ultimate Spider-Man Omnibus Vol. 3 catches the Bendis and Bagley run in full confidence. Ultimate Carnage, longer arcs and Peter's relationship with Mary Jane show a Spider-Man series no longer proving the concept, but using stability to deepen character damage. The volume shows Ultimate Spider-Man no longer proving its concept, but using stability to deepen Peter, Mary Jane and the damage caused by a more modern Marvel universe.

Ultimate Spider-Man Omnibus Vol. 2 is where Bendis and Bagley prove the Ultimate version can sustain long-form Spider-Man drama, not just retell the origin. Ultimate Venom, Kraven and Peter's wider Marvel contact expand the world without losing teen intimacy. The value is momentum: Bendis and Bagley turning the alternate universe into a sustained Spider-Man shelf through dialogue, consequence and Peter's expanding Marvel world.

Jane Foster takes up the mantle of Thor as she battles terminal cancer: each time she transforms, the chemo poison is nullified but the disease progresses. One of the most emotional stories in modern superhero comics — Aaron proves that the worthiness of Mjolnir is not about power but about sacrifice. Includes War of the Realms and the closing of the longest Thor run in history. Russell Dauterman delivers art that matches the epic scale of every page.

Jason Aaron kicks off his run with one of the best Thor stories ever written: God Butcher. Gorr, a villain with real reasons to hate the gods (all his people starved to death while the deities looked on), kills gods for the cosmos. Aaron turns the conflict into a reflection on faith and responsibility. Esad Ribić on the art with digital watercolour pages.

Fourth historical volume with the entry of Gerry Conway as scriptwriter, with John Buscema consolidated on art. Conway came from shining in Amazing Spider-Man (he wrote the death of Gwen Stacy) and brings a more modern narrative to Thor without losing the grandiloquent tone. One of the lesser-known but most solid periods of the classic character.

Foundational Thor stories with Stan Lee and Jack Kirby from his first appearance in Journey into Mystery in 1962. Kirby introduces Asgard as an entire universe with gods, giants and realms connected by a cosmic tree. Jack Kirby in Thor is one of the artistic peaks of American comics: the model that every Thor artist since has imitated.

The Flash by Mark Waid Omnibus Vol. 3 closes Waid's Wally West era with Chain Lightning, legacy futures and the final expansion of the Flash family concept. The value is the emotional payoff to a run about inherited names, speed, connection and the pressure of becoming the Flash after Barry Allen rather than living in his shadow.

The Flash by Mark Waid Omnibus Vol. 2 is Wally West in full confidence: the Flash family, Max Mercury, Impulse, Dead Heat, Abra Kadabra and the Speed Force as philosophy rather than simple power source. Waid turns speed into inheritance, responsibility and identity, which is why this run still defines how later adaptations talk about Flash.

Second volume with the central arcs of the Triangle Era experiment: the time when editorial coordination between the four Superman titles was at its creative peak, with weekly crossover sagas and consequences that spanned months. The heart of an entire decade of the character's history, culminating in the run-up to the Death of Superman. Roger Stern, Dan Jurgens, and Louise Simonson write complementary threads that reward reading in publication order. The most ambitious Superman publishing experiment ever attempted.

Superman: The Triangle Era Omnibus Vol. 1 begins DC's 1990s weekly Superman machine, where Action Comics, Adventures of Superman, Superman and Man of Steel function as one coordinated reading order. The numbered triangles turn the line into a continuous serial rather than separate titles. Jurgens, Ordway, Stern and Simonson build the dense ecosystem that leads toward Death of Superman and the most interconnected Superman publishing era.

Superman: Action Comics by Dan Jurgens Omnibus Vol. 1 is the Rebirth Action Comics shelf: a more traditional Superman voice running alongside Tomasi and Gleason, built around family, classic villains, Mr. Oz mystery and the return of a confident heroic center. The volume matters because it places Superman inside DC's post-Rebirth restoration, where legacy, family and Metropolis action reconnect after the New 52 period.

Closing of the rotating phase before the start of Dan Slott's Big Time. The writers close their individual arcs and prepare the ground for the next phase: Horizon Labs, Spider-Island and the preparation of Superior Spider-Man. The end of Marvel's most ambitious editorial experiment with the character in decades.

The Clone Saga begins: Ben Reilly, a clone of Peter Parker created years ago by the Jackal, reappears in New York and soon the question is radical: who is the real Peter and who is the clone? One of the most talked about and debated sagas of the character. Read from the beginning, it has a coherence and mystery that make it enjoyable.

Civil War from the perspective of the underground Avengers: the team divided and holed up in secret, living in illegality, doubting if they did the right thing. Perfect setup for Secret Invasion. It's Bendis at his most intimate, and central reading to follow the logic of Marvel 2006-2010. Art by Leinil Yu.

Justice League: The New 52 Omnibus Vol. 2 is Geoff Johns turning the launch-era League into the spine of DC's event machine. Trinity War, Forever Evil and Darkseid War make the team less a simple superhero roster and more the point where Lex Luthor, the Crime Syndicate, the Anti-Monitor and the New Gods all collide.

Closing of the Snyder-Tynion run with Year of the Villain and Justice/Doom War. Perpetua, an entity that predates the creation of the DC multiverse, threatens to rewrite the entire reality. Jorge Jiménez pencils epic compositions that define the current Justice League aesthetic. End of the Snyder cycle at DC.

Closing of the longest run ever written about the Hulk: 12 uninterrupted years of Peter David on the title. It collects the final arcs of the run, the process of defusion of the Hulk's personalities and the narrative closure of all the threads that David had opened for more than a decade. End of the cycle.

The moment when Peter David merges the three personalities of the Hulk into a single entity: Professor Hulk. Body of the original, intelligence of Banner, cunning of Grey. Considered by many to be the best Hulk ever written and the version Marvel Studios adopted for Avengers: Endgame. Dale Keown on the art.

Peter David takes Hulk in 1987 and plants the thesis of dissociative disorder: Savage Hulk, Grey Hulk, Banner as separate personalities. This theory was adopted as canon in later film, television and comics. Art by Dale Keown, one of the key names in the Hulk aesthetic of the 90s. Beginning of one of the longest runs ever written about a Marvel character.

The second volume of Morrison's run executes his riskiest move yet: kill off (apparently) Bruce Wayne and let Dick Grayson take up the mantle. The Dick-Damian duo Morrison builds here is one of the best Batman and Robin ever written. Art by Frank Quitely, Morrison's long-time collaborator on All-Star Superman and We3.
