With "The Infinity Saga" wrapping up with Avengers: Endgame and Disney acquiring 21st Century Fox in a merger, the MCU heads into new and unknown territory with a massive roster of well-known characters now available to be brought into the Marvel films' shared universe.

Some fans are concerned that the MCU has reached its peak with "The Infinity Saga" and will only go downhill from here, but with the acquisition of the X-Men, most fans see nothing but a bright future ahead. This list will breakdown key ways that the MCU will only get better with the introduction of mutants and the X-Men.

10 Expand The Universe

The concept is simple. The mere introduction of the X-Men and mutants grows the MCU in ways that audiences have yet to see from the franchise, bringing in superpowers on a global scale and altering the landscape for everyone on the planet including the Avengers themselves.

If Marvel can make general audiences fall in love with a talking tree and a genius raccoon with rage issues, then imagine what they can do with the iconic team of mutants.

9 Further Boost Wanda's Importance

Depending on how Marvel chooses to introduce mutant-kind as well as Wanda's potential connection to mutants, Scarlet Witch could play a major role going forward in the MCU.

It's no secret that she's a mutant in the comics, and Wanda's origin in the MCU could easily be tweaked to accommodate this, with the Mind Stone activating mutant abilities that were already there. She could take on a Xavier-like role with the mutant population, setting up a House of M type storyline.

8 Do Certain Characters Justice

Although many X-Men could fall under this category, these three feel the most short-changed in the entire franchise. The version of Rogue seen in the movies is a far cry from what she's actually like in the comics, both in terms of power set and personality.

Beast saw prominence in the newer X-Men films, but this version of him never lived up to his potential. Cyclops has had debatably the worst run in the X-Men films, with the writers never being able to properly bring to life this ruthless leader who's willing to do anything to protect his fellow mutants. Doing these characters right will draw even more fans to the MCU.

7 Introduce The Original Team

As a way to remove this new take on the X-Men from what has come before, the MCU could focus on the original team of mutants and shy away from flagship characters like Wolverine for a little while.

Avoiding territory that audiences are familiar with will attract more viewers to the MCU by showing the studios' ability to out-perform their competitors and bring to life the X-Men mythology in a way that has never been seen before in the films.

6 New Major Villains

The X-Men comics are rich with compelling and entertaining villains, all of whom can help expand the MCU on a small, one movie scale or over the course of several films in a prominent role.

A fan-favorite villain like Mr. Sinister could further boost the MCU's roster of bad guys. A character like Mystique, who was poorly written after the original X-Men trilogy, could see a complete reversal in a major baddie role. Then, imagine a proper take on Apocalypse, building him up as a Thanos-level threat.

5 Reinvent Characters Seen Already

Iconic mutants like Xavier, Wolverine, and Magneto, who were the face of Fox's X-Men franchise, are not one-note characters. They are incredibly nuanced and have immense depth, and the versions seen in the movies are one of several takes that could be retooled for the MCU.

Finding a way to breathe new life into well-trodden characters is something Marvel specializes in (e.g. Spider-Man: Homecoming) and giving these characters the same treatment will grow the MCU's fanbase while also expanding their roster of heroes with legendary characters.

4 Avengers Vs. X-Men

The Avengers Vs. X-Men storyline is an action-packed and emotional thrill ride that features some epic moments and major confrontations.

Revolving around the Avengers attempting to quarantine the next host of the Phoenix Force to avoid the loss of innocent life and the X-Men pushing back against them to protect their own, this comic could be the perfect source material for the next major MCU event. Crossing over these two major franchises will only lead to goods things for the MCU.

3 Explore Other Core X-Men

There are many famous X-Men characters who either haven't been introduced yet in the movies or who have been but didn't really get their chance to make an impact, like Gambit or Kitty Pryde.

Properly utilizing a character like Storm as an extremely powerful, Black, female mutant with ties to Wakanda would not only be a timely choice, but it also serves to advance the elements of the MCU that are already there and make the sum of its parts stronger.

2 The True Dark Phoenix Saga

The Dark Phoenix Saga is one of if not the best X-Men story of all time. Fox failed not once, but twice when attempting to adapt this famous comic run for their films.

With both of the films bombing with fans and critics alike, Marvel has a rare opportunity to do this story justice and further showcase themselves as the gold standard when it comes to superhero content. The Dark Phoenix Saga has the potential to be its own 22-movie storyline just like "The Infinity Saga."

1 X-Men's Racial Themes

Although diehard fans of the X-Men know of the comic's origins in race relations and social injustices, for general audiences, this isn't common knowledge.

Like what they did with Black Panther, the MCU has the chance to use their superhero films to comment on society on a massive scale by using the plight of mutants to bring to light the hate and discrimination that oppressed groups experience every day of their lives. This will require Marvel to step away from their more comedic and light-hearted filmmaking approach, but many fans would welcome this change.
