Avengers: Secret Wars – MCU’s Biggest Event

If Avengers: Endgame felt like the biggest superhero party in history,
Avengers: Secret Wars is the “we invited the entire multiverse” after-party.
Marvel Studios is planning this film as the grand finale of the Multiverse Saga,
pulling threads from years of movies, shows, and classic
Secret Wars comics into one huge crossover.
Think cosmic stakes, collapsing realities, and more capes on screen than your eyes can reasonably track.

While details are still under wraps, we do know some key facts.
Avengers: Secret Wars is currently scheduled to hit theaters in December 2027 as part of
Marvel Phase Six of the Marvel Cinematic Universe (MCU).
It’s expected to follow Avengers: Doomsday, setting up a one-two punch of
universe-shaking events that could “reset” the MCU’s status quo going forward.
To understand why fans are so hyped, you have to look at both the comics history
and the multiverse storytelling Marvel has been building on screen.

What Is Avengers: Secret Wars?

In simple terms, Avengers: Secret Wars is the MCU’s planned
mega-crossover where heroes from across different franchisesand possibly
different universesface the end of everything as they know it.
The story will likely revolve around the multiverse breaking down,
“incursions” between realities, and a desperate attempt to hold the universe together
when all the rules are collapsing.

On the movie side, the title is inspired by two major Marvel comic events:
the original Secret Wars (1984) and the more recent, multiverse-heavy
Secret Wars (2015). Both stories are huge, both changed Marvel lore in a
massive way, and both give Marvel Studios a lot of material to play with when designing an
all-star Avengers movie that tops everything before it.

The Secret Wars Story in Marvel Comics

The 1984 Battleworld Showdown

The original Marvel Super Heroes Secret Wars (1984–1985) was Marvel’s
first big company-wide crossover. A cosmic being called the Beyonder became
fascinated with Earth’s heroes and villains, snatched them from their lives, and dropped
them on a patchwork planet called Battleworld. His challenge was simple:
“Slay your enemies and all that you desire shall be yours.”

On the “good” side, you had the Avengers, the X-Men, the Fantastic Four, and Spider-Man.
On the “evil” side, you had Doctor Doom, Ultron, Magneto, Kang, and more.
Over twelve issues, Secret Wars delivered:

Doctor Doom stealing the Beyonder’s godlike power.
Spider-Man finding his black alien costume (the future Venom).
Major character shifts, like She-Hulk replacing the Thing in the Fantastic Four.
Huge, toy-friendly battles that still influence Marvel storytelling today.

While the 1984 event was simplergood vs. evil on a battle planetit introduced
core concepts that the MCU can remix: Battleworld, Doom stealing ultimate power,
and an outside cosmic force messing with reality just because it can.

The 2015 Multiverse-Shattering Event

Fast forward to 2015, and Marvel dropped a very different
Secret Wars event, written by Jonathan Hickman.
This version is the one most fans expect the movie to lean on.
Instead of a “fun” crossover arena, the story starts with a nightmare:
multiple universes in the Marvel Multiverse are colliding in catastrophic
events called incursions. When two Earths from different universes
occupy the same space, one reality must be destroyedor both die.

Eventually, the final incursion wipes out everything.
Only fragments of destroyed universes survive, fused together into a new Battleworld
ruled by a godlike version of Doctor Doom.
Heroes like Reed Richards, Black Panther, and others must challenge Doom’s false “peace,”
restore the multiverse, and decide what the new normal looks like.

This story is dense, emotional, and incredibly cinematic.
Themes of sacrifice, second chances, and rebuilding reality are baked in.
For a Marvel Cinematic Universe currently obsessed with the multiverse,
it’s basically a blueprint for a final, universe-redefining multiverse saga movie.

From Page to Screen: How the MCU Is Building Secret Wars

Marvel hasn’t adapted Secret Wars overnight.
The MCU has been quietly laying multiverse groundwork across several projects:

Loki introduced the Sacred Timeline, the Time Variance Authority,
and the idea that there used to be countless universes before a multiversal war.
Spider-Man: No Way Home cracked open the multiverse with villains
and Spider-Men from past movie franchises stepping into MCU continuity.
Doctor Strange in the Multiverse of Madness brought in
Illuminati variants, alternate realities, and explicitly talked about
incursionsa direct Secret Wars concept.
Other projects, from animated series to upcoming movies, keep teasing
variants, branching timelines, and universes on a collision course.

On the calendar, Avengers: Secret Wars is planned as the closing event
of the current Avengers saga, arriving after Avengers: Doomsday.
Together, these movies are expected to function like
Infinity War and Endgame: one setting the disaster in motion,
the other delivering the final resolution.

Characters and Teams Likely to Shape the Story

Marvel has not released an official, full cast list for
Avengers: Secret Wars, and a lot will stay under wraps for as long
as possible. But based on the current MCU multiverse saga and
the comics inspiration, there are some strong guesses.

The Classic Avengers and Their Successors

Expect a mix of legacy heroes and newer faces:

Sam Wilson’s Captain America, carrying the shield into the next era.
Doctor Strange, whose magic and knowledge of incursions make him essential.
Spider-Man, a fan favorite and multiverse veteran at this point.
Shang-Chi, wielding the Ten Ringsmysterious artifacts that might tie into cosmic forces.
Other heroes from Wakanda, the Guardians legacy, and Earth’s ground-level teams.

The key pattern? The MCU has spent Phases Four and Five handing mantles to new
heroes while keeping a few veterans around. Secret Wars is the perfect place
to bring them all together and test their limits.

Fantastic Four, Mutants, and Legacy Heroes

One of the big selling points of Secret Wars as a movie is the potential
to finally bring everyone under one giant narrative roof:

Fantastic Four, who are central players in the 2015 comics event.
Mutants and X-Men, who could arrive through multiverse shenanigans and stick around afterward.
Legacy heroes and variants from older Marvel films, returning for one last ride.

Marvel Studios has already shown a willingness to pull surprise cameos
from past franchises. Secret Wars is the one place where
“everyone shows up” isn’t just fan serviceit’s the whole point.

The Villains: Doctor Doom, Kang, and Beyond

On the villain side, the comics point to two major players:

Kang the Conqueror and his variants, tied to the multiverse
and time itself.
Doctor Doom, who becomes a god-emperor in the 2015 Secret Wars
storyline after seizing impossible power to save what’s left of reality.

Exactly how the MCU balances or reshuffles these villains is still evolving,
especially given real-world production changes. But from a story standpoint,
Secret Wars almost begs for Doom to step into the spotlight as a
long-term big bad, with Kang, the Beyonder, or other cosmic forces
shaping the conflict.

Why Avengers: Secret Wars Matters for the MCU

Marvel Studios has hinted that Avengers: Secret Wars will
“reset” the MCU more than outright reboot it. That means:

Some characters may get definitive endings.
New heroes and teams may emerge as the focus going forward.
Continuity might be streamlined, cleaned up, or selectively rewritten.

In other words, Secret Wars gives Marvel a chance to pay off
years of storytelling and clear the decks for whatever the next era will be
whether that’s a stronger focus on mutants, cosmic stories, street-level heroes,
or something completely new.

How to Prepare: Comics, Movies, and Shows to Watch

Want to go into Avengers: Secret Wars feeling like the person in the theater
who actually understands what a “multiversal incursion” is?
Here’s a practical prep list.

Essential Comics

Marvel Super Heroes Secret Wars (1984) – the original Battleworld story.
Secret Wars (2015) – the multiverse-ending epic that’s likely the main inspiration.
New Avengers and related runs leading into 2015 Secret Wars – these explain incursions
and the moral compromises heroes make to stop them.
Key Fantastic Four arcs by Jonathan Hickman – to better understand Reed Richards, Doom,
and their rivalry.

MCU Watch List

Avengers: Infinity War and Avengers: Endgame – to see how Marvel handled its last big crossover.
Loki (both seasons) – essential for understanding timelines, variants, and the TVA.
Spider-Man: No Way Home – a crash course in live-action multiverse crossovers.
Doctor Strange in the Multiverse of Madness – your first on-screen lesson in incursions.
Any future projects that tease Avengers: Doomsday and multiverse fallout.

You don’t have to consume all of this to enjoy the movie, of course.
But if you love spotting deep-cut references and understanding why fans gasp
when a random portal opens, this prep will make Secret Wars
hit a lot harder.

Fan Experiences and Getting Hyped for Avengers: Secret Wars

One of the best parts of a huge Marvel event isn’t just the movie itself;
it’s the build-up. Between now and the release of
Avengers: Secret Wars, fans have a lot of ways to turn the wait into an experience.

Start with a Secret Wars reading club.
Grab a few friends, pick up the 1984 and 2015 events, and read through them together.
The contrast alone is fun: the original is very “’80s toy commercial but make it epic,”
while the 2015 run feels like a prestige drama about the end of everything.
You can debate which Battleworld domains you’d want to live in
(answer: probably not the zombie one).

Then build a Multiverse Saga watch marathon.
Instead of just rewatching the four Avengers movies, mix in the weirder multiverse entries:
Loki, No Way Home, What If…?, and
Multiverse of Madness.
You’ll start seeing patterns: how often Marvel mentions branches, variants,
incursions, and consequences for messing with the fabric of reality.
It’s like assembling a conspiracy board, but with popcorn instead of red string.

Conventions and fan events will also ramp up the Secret Wars hype.
Expect cosplayers to go wild with mash-ups:
multiverse variants of heroes, Doom-inspired armor,
or Battleworld versions of familiar characters.
If you’ve ever wanted to cosplay as “Doctor Strange but also a cowboy from a Western domain,”
this is your moment.

Online, theories are half the fun.
Fans will be dissecting every trailer frame,
arguing over whether Doctor Doom should become the next long-term villain,
and debating which cameos count as essential versus pure nostalgia.
Even if you don’t dive into spoilers, following the conversation can make the eventual twists
feel like the payoff to a years-long group puzzle.

Finally, think about what Secret Wars could mean for the future.
Maybe the MCU will lean more into mutants.
Maybe it will refocus on smaller, more grounded stories after one last multiverse explosion.
Treat the lead-up as a chance to appreciate how far the MCU has comefrom a single armored guy
in a cave to a universe where entire timelines are on the lineand to imagine where it could go next.

Conclusion: One Massive Crossover Worth Waiting For

Avengers: Secret Wars is shaping up to be more than just “another Avengers movie.”
It’s the endpoint of Marvel’s multiverse experiment, the payoff to years of setup,
and a rare opportunity to bring together heroes, villains, and worlds that have never shared
the screen before. By drawing on the classic Secret Wars comics, weaving in the
multiverse saga, and potentially re-shaping the MCU for the next decade,
this film is designed to feel like an event in every sense of the word.

Whether you’re here for the emotional arcs, the universe-level stakes,
or just the joy of seeing wildly different characters fight side by side on Battleworld,
Avengers: Secret Wars promises a cinematic experience that’s big, strange,
and unforgettable. Now’s the time to catch up, dive into the comics,
and get ready for the moment when Marvel asks the question it’s been building toward:
what happens when all worlds collide, and who gets to build what comes after?

Marvel comics, the MCU multiverse saga, and fan-favorite heroes in one epic crossover.

sapo: Avengers: Secret Wars is set to close out Marvel’s Multiverse Saga with
the most ambitious Avengers movie yet, blending the classic Secret Wars comics with years of
MCU storytelling. From Battleworld and universe-shattering incursions to the rise of villains
