AVENGERS: DOOMSDAY Rumor Reveals Reason For Avengers vs. X-Men Battle - SPOILERS

The latest Avengers: Doomsday rumour reveals what leads to the Avengers and X-Men clashing, and the state of the latter team's world when we catch up with them in the movie.

Avengers: Doomsday is shaping up to be the biggest MCU movie yet, with the Avengers, X-Men, Fantastic Four, and Spider-Man all set to share the screen while battling Robert Downey Jr.'s Doctor Doom.

A combination of online rumours and comments from a couple of Avengers: Doomsday stars has confirmed that there will be a clash between the Avengers and X-Men (with Marvel's First Family thrown in for good measure). 

Now, we may have some insights into what leads the heroes to go to war with each other. 

According to insider @MyTimeToShineH, "In Avengers: Doomsday, the X-Men [have] been through many Incursions, so when the Avengers and [Fantastic Four] come to their universe to try and help them, they assume they came there to destroy them, and that's why they fight."

This is classic superhero storytelling. Heroes meet, they fight, and eventually put their differences aside to battle a much greater threat. 

We're assuming that's the plan for Avengers: Doomsday, anyway, and the dynamic between these two teams promises to be fascinating for fans who have long dreamed of seeing them share the screen.

This latest leak also explains what we've been hearing about some key members of the X-Men—including Jean Grey and Storm—being dead when we find them in this movie. After all, if they've fended off multiple Incursions, some mutants are bound to have fallen in combat.

While there's massive excitement surrounding the return of 20th Century Fox's X-Men, we don't know how big a role they'll have in this movie. 

Marvel Studios intends to reboot the X-Men franchise post-Avengers: Secret Wars, so it will need to be careful not to distract from that. Wesley Snipes' return as Blade in Deadpool & Wolverine already backfired on them to some extent, as many fans quickly expressed a desire to see more of him as the Daywalker in place of Mahershala Ali.

What are your hopes for the X-Men in Avengers: Doomsday this December? Relive their teaser below, and let us know your thoughts in the comments section.

Avengers: Doomsday officially stars Chris Evans, Chris Hemsworth, Anthony Mackie, Winston Duke, Tom Hiddleston, Sebastian Stan, Letitia Wright, Paul Rudd, and Robert Downey Jr. Wyatt Russell, Simu Liu, Tenoch Huerta Mejia, Mabel Cadena, Florence Pugh, Danny Ramirez, David Harbour, Hannah John-Kamen, Lewis Pullman, and India Rose Hemsworth all make their Avengers franchise debuts.

The Fantastic Four: First Steps leads Pedro Pascal, Vanessa Kirby, Ebon Moss-Bachrach, and Joseph Quinn join them, as do X-Men franchise stars Kelsey Grammer, Patrick Stewart, Ian McKellen, Alan Cumming, Rebecca Romijn, James Marsden, with Deadpool & Wolverine star Channing Tatum. The trades have pointed to Ryan Reynolds and Hayley Atwell also appearing in Avengers: Doomsday.

The Russo Brothers direct Avengers: Doomsday and Avengers: Secret Wars from a screenplay by Stephen McFeely, with whom they previously collaborated on the Avengers and Captain America franchises. Loki and Doctor Strange in the Multiverse of Madness's Michael Waldron has also been enlisted to help.

Avengers: Doomsday is set to be released on December 18, with Avengers: Secret Wars scheduled to arrive on December 17, 2027.

I’m confused, how is it a spoiler if it’s a rumor?

@SCOTTHZ972 - Yesterday, someone was complaining about a banner image of a Daredevil Funko Pop being a spoiler. Better to be safe than sorry with these things.

@JoshWilding - I'm just giving you a hard time. It's all good man. I'm sure you get comments about your articles 24/7/365, in fact I know you do. Keep on trucking.

So, the X-men has just been killing universes? Wow. Then, they are selfish villains and it makes sense the conflict.

@artofwilldeonne - I read that as anyone coming from another universe into theirs was captured or killed not destroying where they came from otherwise they'd have come after 616 WAY sooner after the prior incursion in The Marvels. I mean shot first ask questions later isn't the best way for a hero to act so IF this is true likely more to it than that, as in the Avengers come in hot due to whatever they believe they know about them and their timeline but...

...Monica Rambeau will likely be used to resolve that fight at an appropriate point as she could talk the Avengers down IF anyone who knows who she is is there such as Danvers (and presumably by then the Xmen will trust her too).

Course almost everything in this rumor was guessed the second they announced Secret Wars prior to any news on which characters let alone cast would be involved so could be made up BS anyway (even if highly probable to be something close to it in the script).

@ferf - Depends on what metal if any used for make his armor I guess, or what tech/magic imbued in it to counter his powers.

Interesting if true…

I had thought that all it would take to destroy one or both worlds is just a single incursion but I guess that’s not true (though makes sense given the Sinister Strange universe we saw in MOM was destroyed by an incursion but not fully).

Anyway , this will be probably where we get that Mr Fantastic vs Nightcrawler fight that Alan Cumming spoiled…

Regardless , it will be fun to get some classic superhero tropes such as the misunderstanding fight in this!!.

Well, hopefully they will actually fight some bad guys at some point.

@LSHF - lol

This will likely be a 5 min action scene and then we move onto them fighting Doom.

There’s bound to be more X-men in the movie. There’s no way 7 X-men are able to contend with all of the Avengers, F4, Shang Chi, and Spider-man. That’s like what, 7 vs 20?

@Odekahn - it’s Xmen team not Xmen army

@Matchesz - not sure I understand your point?

So the typical superhero misunderstanding that leads to hero-on-hero fight... Sure as hell hope it's more complicated than that.

As long as this is the only Avengers v. X-Men story they attempt on screen, that's fine.

I wonder how much longer Marvel is gonna milk the multiverse teat? Dr. Strange 2 was a hot turd except for the cameos and murder spree. Deadpool/Wolverine was pleasantly excellent b/c Reynolds leveraged his popularity to make the R movie he wanted to make without Marvel neutering it.

The Russos are pretty good directors. But honestly, Whedon was better and more adventurous and he invented the franchise model after Iron Man got the ball rolling with Favreau.

Feige is a corporate guy at heart.
