Could Deadpool be the reason the X-Men and Avengers universes collide? Here’s the theory

People are starting to think Deadpool is about to blow up the whole Marvel universe as we know it. Or, well, mash it all together, at least. This whole theory is picking up steam because Marvel has been obsessed with the multiverse lately. Deadpool & Wolverine (2024) just threw gasoline on the fire, and everyone is already looking ahead to Avengers: Secret Wars (2027) like it’s going to be the final fight of all superhero mashups.

So, Deadpool has always been a snarky, self-aware wildcard who kind of does his own thing. Mostly because Fox owned his movies, so he was off in his own corner. But then Disney gobbled up Fox, and all the toys are in the same sandbox. Deadpool & Wolverine is the first time they’re really messing with that with Wade and Logan, both from the Fox X-Men side, running in the MCU’s multiverse.

Except, at the end of the movie, instead of nuking the Fox X-Men universe into oblivion, Deadpool and Wolverine actually save it. Earth-10005, for the ones keeping score. So now there’s this huge opening for the universes to crash together, or get tangled up because Deadpool can’t leave well enough alone.

And with Secret Wars on the horizon, which is Marvel’s excuse to throw every hero from every timeline onto one massive battlefield, it’s not crazy to guess Deadpool is going to be the bridge or the chaos gremlin who helps smash the X-Men and Avengers worlds together. He talks to the audience, breaks every rule, and pretty much does whatever he wants, so if anyone is gonna poke a hole in the multiverse and drag Wolverine through it, it’s him.

How Deadpool could cause the collision

Let’s go off-script for a second because Deadpool at the center of an X-Men/Avengers universe pile-up idea is not just some random fan theory; it’s got roots both in the multiverse rules Marvel cooks up and in the real-world business side of Hollywood. If you want to wrap your head around it, you have to look at how the multiverse even started, the rules it plays by, all these watchdog agencies, Deadpool’s meta superpowers, and why it even matters if universes stay separate. Plus, how all this might add up to a massive MCU crossover event may be something to behold.

Some multiverse backstory

So Marvel’s multiverse is a bunch of parallel worlds, each one remixing its own group of heroes and disasters. This isn’t new; it goes way back to comics like Avengers #85 in 1971, and gained prominence with crossover stories like Secret Wars (1984), which merged multiple realities temporarily.

Jump to the movies, and things got official with Doctor Strange in the Multiverse of Madness, and Loki’s show was the real multiverse guide. That’s when we got the Time Variance Authority (TVA), an organization that polices the “sacred timeline” to prevent timeline branch-outs that could cause a multiversal war.

MCU’s cheat sheet for alternate universes:

- Earth-616: The main MCU timeline and universe.

- Earth-10005: Fox X-Men universe, home to Deadpool, Wolverine, and other Fox-produced X-Men.

This handy multiverse mumbo-jumbo lets Marvel drag in Spider-Men or X-Men from literally anywhere.

Deadpool: The meta-nuke

Deadpool (Wade Wilson) isn’t just a wisecracking mutant. He has healing powers and combat skills, but that’s not what makes him stand out. What really sets him apart is the fact that he knows he’s in a comic, or a movie, or whatever. The guy literally talks to us. He’ll call out the writers, the studio, Ryan Reynolds, probably you, and me if he could. He is Marvel’s way to poke holes in its own logic.

Why does that matter? Because when you’ve got a character who’s not playing by the rules of his own universe, he’s the wildcard who can literally jump between universes, or screw them up just for laughs.

Writers use Deadpool’s meta-awareness gag to smash the walls between universes. He’s the only guy who could turn canon into a joke and still make it matter.

The TVA, Deadpool, and how things get messy

Now, Deadpool & Wolverine (2024) brought in the TVA to actually recruit Deadpool. These multiverse police are tapping the most unpredictable man in Marvel to help fix reality.

TVA has got the tech and the authority to hop between timelines, and Deadpool is a walking chaos. He’ll help, but he’ll also probably prank the whole operation.

So, when they hand Deadpool the keys to the multiverse, you know something is gonna break. And if you’ve seen Doctor Strange in the Multiverse of Madness, you know what an “incursion” is: when two universes occupy the same space and collide, destroying one or both. Deadpool has a history of screwing with time (time-hopping at the end of Deadpool 2), so it’s a miracle the multiverse isn’t already a mess.

Keeping Earth-10005 alive: Why bother?

In Deadpool & Wolverine, instead of letting the old Fox X-Men universe croak, Deadpool and Wolverine save it. They don’t fold it into the MCU; they leave it hanging out there. Now you’ve got a whole universe floating around, not connected, not destroyed.

That unresolved thread is Marvel daring itself to do a universe-smashing crossover, with Deadpool as the guy who probably lights the fuse. So, Deadpool isn’t just hanging around for jokes; he is the ticking time bomb at the center of a potential X-Men/Avengers universe collision.

Meta-awareness and narrative flexibility

Deadpool’s whole shtick is that he knows he’s in a movie—and not just any movie, but one tangled up with Disney, Fox, Sony, and more. The guy literally peeks behind the cinematic curtain. He cracks jokes about the MCU, the Fox stuff, and Sony’s Spider-Man. That’s not just for laughs. When Deadpool is on screen, the whole idea of what’s “real” in the Marvel Universe starts to wobble. He’s like a multiverse glitch that could either wreck everything or glue it all together, depending on how he feels that day.

Marvel could just drop him in as a punchline and a plot device to explain away any universe collision.

Why Deadpool is the bridge, not just another face in the crowd

Anyone can fall through a portal and end up in another universe. Happens every time in comics. But Deadpool is built for this mess. He hangs with mutants like Colossus, crashes the Avengers, and shatters the fourth. Nobody else can call out the absurdity of mixing X-Men with Iron Man and make it work.

Iron Man would just stand there, all stoic and confused, while Deadpool is already making jokes about Disney mergers. Ever since Disney bought Fox, they've needed a character to handwave all this corporate gibberish and keep fans laughing.

Secret Wars: The big Marvel mashup

In the comics, Secret Wars was Marvel throwing all their universes together to form a Battleworld—a planet, stitched together from bits of different worlds and timelines.

Now, the MCU has Avengers: Secret Wars lined up for 2027, and everyone is expecting it to be the ultimate crossover. MCU heroes, Fox’s X-Men, Sony’s Spider-People, and everybody else.

Here’s where Deadpool comes crashing through the fourth wall. Whether he means to or just trips over the TVA’s tech, he could be the spark that triggers the big ‘incursion’. That’s what sets up Battleworld, and blows up the multiverse as we know it.

With Deadpool’s reality-bending silliness, meta-jokes, and now his gig with the TVA, he is the perfect one to set off this universe-shattering event. If anyone’s gonna break reality and glue it back together with duct tape, it’s gonna be Wade Wilson.
