Avengers Doomsday : Les X-Men vont-ils enfin rejoindre l'équipe ?

The Marvel Cinematic Universe is gearing up for its next epic crossover event—Avengers Doomsday—and rumors suggest this could be the long-awaited moment when the X-Men officially enter the Avengers’ timeline. 

As Marvel Studios prepares to merge its multiverse storylines, speculation is growing that Avengers Doomsday will serve as the catalyst for mutant-kind’s introduction into the MCU’s main continuity.

What Avengers Doomsday Could Mean for the MCU

Avengers Doomsday is poised to become one of the most consequential installments in Marvel Cinematic Universe history, serving as both a culmination of Phase Six and a bridge to the franchise’s future.

Following the reality-shattering events of Secret Wars, this film is expected to explore the concept of an “incursion” in depth—a phenomenon where parallel universes collide and destroy one another, potentially rewriting the very fabric of Marvel’s cinematic reality.

According to exclusive reports from ScreenRant, the incursion storyline will likely provide Marvel Studios with several strategic opportunities to reshape the MCU:

Soft-Rebooting Character Arcs

The multiversal collapse could allow Marvel to:

• Refresh certain character origins without full recasting;
• Retcon narrative elements that no longer serve the overarching story;
• Introduce alternate versions of established heroes.

This approach would mirror the comics’ Secret Wars (2015) event, which similarly used universe-altering consequences to streamline continuity.

Merging the X-Men Universe

The incursion event creates the perfect narrative mechanism to:

• Absorb Fox’s X-Men continuity into the main MCU timeline
• Preserve key performances (like Hugh Jackman’s Wolverine) while recasting others
• Establish that mutants “always existed” in the MCU through reality restructuring

Efficient Mutant Introductions

Rather than lengthy origin stories, Avengers Doomsday could:

• Present established X-Men teams already operating in the shadows;
• Use the incursion to awaken latent mutant genes worldwide;
• Introduce popular characters via dramatic multiversal arrivals.

The film’s ominous title—Doomsday—strongly suggests permanent, far-reaching consequences for the MCU. Industry analysts speculate this could include:

• The death or retirement of several founding Avengers;
• Fundamental changes to Earth’s geopolitical landscape;
• The emergence of new superhuman factions.

Marvel Studios president Kevin Feige has hinted at IMDb’s Doomsday page that the film will “redefine what audiences expect from team-up movies”, suggesting unprecedented scale and stakes.

The aftermath will likely establish the status quo for Marvel’s Mutant Saga and beyond, making Avengers Doomsday essential viewing for understanding the MCU’s next decade of storytelling.

Are the X-Men Finally Entering the Avengers Timeline?

Several compelling clues suggest Avengers Doomsday will be mutants’ proper MCU debut:

Marvel’s Recent Casting Choices

Fan Theories on Avengers Doomsday’s X-Men Connection

The most popular theories circulating online propose:

• The “House of M” Adaptation: Wanda Maximoff could rewrite reality to make mutants always have existed;
• Multiversal Merge: the incursion event permanently combines Fox’s X-Men universe with the MCU;
• Secret Wars Aftermath: battleworld’s collapse leaves mutants integrated into the main timeline.

IGN’s analysis suggests Marvel may use Doomsday to explain why mutants haven’t been mentioned before—perhaps they’ve been hidden by Professor X’s mental powers.

What to Expect from Avengers Doomsday

Avengers Doomsday is shaping up to be a seismic event in the MCU, with industry leaks and Marvel’s established patterns suggesting several game-changing developments. Here’s a detailed breakdown of what audiences can anticipate from this pivotal crossover film:

Major Character Deaths

Insider reports indicate Avengers Doomsday will feature at least two significant fatalities—a move that could permanently alter the MCU’s power structure. Speculation centers on:

• Original Avengers facing heroic send-offs to make room for new leadership;
• Legacy characters from Phase 4/5 potentially being sacrificed to raise stakes;
• Surprise returns of departed heroes (via multiverse variants) only to meet tragic ends.

These deaths are expected to have lasting consequences, potentially triggering the rise of mutantkind in the MCU’s main timeline.

The X-Men’s Official MCU Debut

Reliable sources suggest 3-5 core X-Men members will be properly introduced, likely including:

• Cyclops as the tactical leader of the mutant faction;
• Jean Grey (possibly with Phoenix Force implications);
• Storm to establish the global reach of mutantkind.
• A recast Wolverine in a supporting role before his solo films

The film may use the incursion event to explain their sudden appearance—either through reality rewriting or multiversal migration.

Power Shifts Among Earth’s Mightiest Heroes

The aftermath of Secret Wars and the mutant introduction will force the Avengers to adapt to:

• New political dynamics with mutantkind being feared/hated;
• Internal divisions over how to handle the X-Men’s arrival;
• Power vacuums left by departing or fallen members.

This could set up interesting conflicts, such as:

• Captain America (Sam Wilson) clashing with Cyclops over leadership;
• Doctor Strange grappling with the mystical implications of mutant abilities;
• Spider-Man serving as a bridge between humans and mutants.

Post-Credit Teases for the Mutant Saga

Marvel’s signature post-credit scenes will likely:

• Introduce key villains like Mister Sinister or Apocalypse;
• Show the formation of Xavier’s School for Gifted Youngsters;
• Hint at the Sokovia Accords being revised to address mutant registration.

Expanded Universe Connections

The film’s repercussions will extend beyond theaters:

• Disney+ shows like X-Men ’97 may get direct tie-ins;
• Games such as Marvel Rivals could feature Doomsday-inspired character rosters.
• Comics may launch companion miniseries exploring alternate outcomes.

With Marvel Studios keeping plot details tightly guarded, Avengers Doomsday remains one of the most anticipated—and potentially franchise-altering—entries in MCU history. 

The film is expected to lay the groundwork for the next decade of Marvel storytelling while delivering the epic crossover spectacle fans expect.
