One of the biggest events in the Marvel Universe, Secret Invasion, is getting a Disney Plus streaming series in 2023. As you've probably noticed, Marvel Comics is all about big event storylines. From the recent Daredevil-centric crossover Devil's Reign to the current Avengers/X-Men/Eternals three-way standoff Judgment Day, rarely do months go by in which Marvel Comics isn't waist-deep in at least one event.
And that preoccupation with events isn't limited to just Marvel comic books. Civil War, The Infinity Gauntlet, Spider-Verse, and Age of Ultron are all comic book storylines that have been adapted into MCU stories, with the upcoming Secret Invasion and Armor Wars Disney Plus streaming series both having similar roots in comics.
While everyone has their preferred ranking for the best Marvel stories, we think events should be judged by their impact on the Marvel Universe. Below, check out Newsarama's in-depth look at the best, most impactful Marvel Comics events of all time.

Early on in The Infinity Gauntlet, it seemed as if it would be the series that would change everything – half of humanity was dead! Natural disasters had altered the very world our characters lived in! – but everything was reset by the series' end, with the only lasting effects being that a new Warlock series could be spun out of the whole shebang. A masterclass in the whole 'No change, just the illusion of change' thing.
A spiritual follow-up, Infinity, promised more lasting change - while Thanos and the gems were still a part of the story, the biggest fallout from that event was the unleashing of the Terrigen Mists and unlocking the powers of thousands if not millions of latent Inhumans.

10. Fear Itself
2011's massive event series Fear Itself featured developments that certainly felt big at the time, and by the final issue of the series, Bucky (who was Captain America at this point) and Thor were still dead, and Paris was a city of stone statues instead of people.
And then came the three epilogue issues that, one by one, undid each of those things. Cleaning up after itself or a statement on the impermanence of death in superhero comic books? Potentially both, as the writer Matt Fraction told Newsarama at the time: "Death in superhero comics is meaningless. It's the escape. It's the resurrection. That's the story. These issues were kind of the chance to focus on that under the microscope, once all the pyrotechnics were done."

9. Secret Invasion
It's tempting to suggest that ending the then-long-running thread of 'Who Do You Trust?' and 'Maybe one of these characters is an alien shapeshifter' is enough to make the end of Secret Invasion an important event in and of itself.
In terms of narrative, though, the series moved Tony Stark away from the position of power that he'd been in for months, and placed everything in the hands of Norman Osborn, heralding a period where the bad guys really had won... Well, at least until they started messing everything up for themselves.
The title of this series, if not its entire premise, will be adapted for an upcoming Disney Plus MCU show.

8. Secret Wars
This is a tough one because it wasn't the end of Secret Wars that changed everything, but the start. Still, that's what you get when the entire series is essentially a 12-part flashback to explain away the changes already seen in everyone's regular book.
She-Hulk in the Fantastic Four and Spider-Man's black costume that would later turn out to be Venom are two changes that may not have stuck forever but ended up becoming surprisingly welcome additions to the canon. Less so, that giant dragon girlfriend for Lockheed, of course. Thankfully, 'Rocky Grimm, Space Ranger,' didn't make a comeback when Secret Wars was revived in 2015 - but he did end up back in space with the Guardians of the Galaxy.

7. Schism
Unusually, Schism was an event book that existed for the sole purpose of the end result: Splitting the X-Men franchise in two. And yet it worked, and in the process refreshed the franchise in a way that nothing else had managed since the days of Grant Morrison.
It wasn't just the clash of ideologies that surprisingly came to life, but the characters presenting those ideologies. 'Wolverine as Teacher' made perfect sense, even as it seemed counter-intuitive, a sign that something has gone right.

6. Avengers vs. X-Men
Aside from the death of Charles Xavier – as if we've never seen that before – and the criminalization of the 'Phoenix Five,' what exactly did Avengers vs. X-Men achieve for the larger Marvel Universe?
Well, in theory, it ushered in an era where the X-Men and cosmic characters were brought further into the wider Marvel Universe, which ended up being a quieter, but more meaningful change to Marvel than we normally see from these event books.

5. House of M
"No More Mutants."
With those three words, the Scarlet Witch upended the X-Men franchise in a seemingly out-of-nowhere denouement to the alternate reality series, reducing the mutant population of the Marvel Universe to less than 200 and beginning a race against extinction that finally came to an end a decade later.
House of M rewrote the Marvel Universe - literally - creating a place where mutants were in charge under the leadership of Magneto. The fallout of the event had massive ramifications on both the X-Men and Avengers for years to come and set up plot points still referenced in both franchises today.

4. Mutant Massacre
Mutant Massacre wasn't an event crossover in the way that we consume and understand them today. There was no core limited series in which the main events occurs. There wasn't even a 'Mutant Massacre' banner on the covers of the tie-ins. But despite lacking the standard trapping of a Marvel event had the kind of impact that a crossover such as 'Maximum Security' could only dream of.
This storyline marked the end of the X-Men's stay at Xavier's school for close to the next 100 issues and included the deaths of a handful of familiar faces, the introduction of new characters and revised team rosters, Warren Worthington/Angel being wounded to the point his wings are amputated, and a more somber tone for a franchise already known for its dourness.

3. Onslaught
Hey, remember that time when a crossover ended with the Marvel Universe devoid of some of its most famous characters? Now, we can look back and say that the absence of the Fantastic Four, Avengers, and their respective members was only a temporary thing, but at the time that was far from a known fact, meaning that the 'Onslaught' saga genuinely did have that feeling of having changed everything in real ways, possibly forever.
Onslaught has made a couple of comebacks, including as 'Red Onslaught,' a twisted manifestation of Xavier's powers in Red Skull's body - a nightmare that finally ended with Xavier's resurrection. Most recently he resurfaced on Krakoa in the one-shot X-Men: The Onslaught Revelation #1.
Xavier is now back whole, helping lead the newly-formed mutant island nation of Krakoa.

2. Civil War
Oh, Civil War, how you changed the Marvel Universe. There was that whole 'You work for the government or you're a criminal' thing, that whole 'Now no one gets on with anyone else' thing, the skillful creation of a second Avengers book for the first time since West Coast Avengers, but more importantly, it changed the Marvel Universe by changing the tone of the Marvel Universe.
Even though House of M's decimation of mutantkind came earlier, it was Civil War that felt as if it actually had an impact on the style and content of all of Marvel's titles for months afterward, setting the pattern for events that followed.
And Civil War is the Marvel event that just keeps giving, not only as the inspiration for Captain America: Civil War, but in 2016's comic book sequel, Civil War II.

1. Secret Wars
... Secret Wars, again? Déjà vu? Not exactly. See, this entry is about the second event to use the title Secret Wars.
The fallout of the newer iteration of Marvel's first-ever crossover event included the Ultimate Universe ending completely, with aspects of it, including Miles Morales and the Triskelion, folded into the mainstream Marvel Universe, the world at large believing the Fantastic Four were dead while they rebuilt the multiverse, and the death of Marvel's oldest character, Namor, in the aftermath (he got better.)
While the in-universe consequences stemming directly from Secret Wars are, on their own, enough to give this event a spot high up on this list, the real-world implications are even more staggering. During its run, the entire Marvel Comics line was put on hold while tie-ins explored the various aspects of the makeshift, hybrid world the storyline occurred on, Battleworld, only to see every single Marvel comic book relaunched with a new #1 as part of the 'All-New, All-Different' Marvel Universe.
The new universe very closely resembled the old one, making this less of a reboot and more of a retooling, but it's likely as close as the venerable company will ever come to fully rebooting its universe, as its very proud of the fact DC has rebooted its universe multiple times and its has not.
