The Marvel Cinematic Universe (MCU) is gearing up for a multiversal spectacle with Avengers: Doomsday, and a new rumor suggests that the X-Men will play a significant role in its sprawling narrative. Among the most intriguing whispers circulating among fans is a report that Avengers: Doomsday could reveal that Gambit, the charismatic mutant from Deadpool & Wolverine, hails from the same universe Monica Rambeau visited in the post-credits scene of The Marvels. While this remains speculative and unverified, the rumor has ignited excitement about how the MCU might weave its mutant characters into the broader multiversal tapestry.
According to a report from QuidVacuo, a recent exclusive about The Fantastic Four: First Steps showcased at CCXP dropped hints of major MCU connections, including a potential revelation for Avengers: Doomsday. The rumor posits that the film may confirm Gambit’s universe—where Channing Tatum’s kinetic-energy-wielding Cajun stole the show in Deadpool & Wolverine—as the same reality Monica Rambeau, portrayed by Teyonah Parris, was transported to in The Marvels. That universe, briefly glimpsed in The Marvels’ post-credits scene, featured a world with familiar yet distinct versions of characters, teasing the presence of X-Men. If true, this connection could tie Deadpool & Wolverine’s multiversal antics to the MCU’s larger narrative, but fans should treat this claim as speculative until Marvel Studios provides official confirmation.
This rumored connection would be a strategic move by Marvel to integrate the X-Men into the MCU’s multiversal framework. Gambit’s electrifying debut in Deadpool & Wolverine left audiences clamoring for more, and linking his universe to Monica Rambeau’s destination could pave the way for deeper mutant involvement. Avengers: Doomsday, directed by the Russo Brothers and featuring Pedro Pascal among others, is already rumored to connect with The Fantastic Four: First Steps and Thunderbolts, positioning it as a pivotal chapter in the MCU’s Phase Six. However, without official word from Marvel, this Gambit-Rambeau link remains an exciting but unconfirmed possibility that has fans buzzing with anticipation.
What This Could Mean for the MCU
If this rumor proves accurate, it could have significant implications for Monica Rambeau’s storyline. Left stranded in an alternate universe at the end of The Marvels, Monica’s fate remains unresolved, and Avengers: Doomsday might depict her navigating this X-Men-filled reality alongside Gambit. This setup would align with the MCU’s recent focus on multiversal storytelling, as seen in Spider-Man: No Way Home and Doctor Strange in the Multiverse of Madness. The potential for crossovers between mutants and established MCU heroes adds another layer of intrigue, promising a narrative that bridges Marvel’s past and future.
Rumored X-Men Actors in Avengers: Doomsday
The speculation doesn’t stop with Gambit’s universe. Rumors are swirling about which X-Men actors might appear in Avengers: Doomsday, though nothing has been officially confirmed. Channing Tatum is at the top of the list, with fans and reports strongly suggesting he’ll reprise his role as Gambit, capitalizing on his scene-stealing performance in Deadpool & Wolverine. Ryan Reynolds is also rumored to return as Deadpool, potentially sharing the screen with Gambit again, building on their dynamic chemistry from the 2024 hit. Hugh Jackman’s Wolverine is another name frequently mentioned in fan discussions, though his involvement remains unconfirmed and tied to his arc in Deadpool & Wolverine. There’s also chatter about other X-Men like Storm or Cyclops making appearances, but no concrete casting reports have surfaced. These rumors, while thrilling, should be approached cautiously until Marvel Studios releases official casting details.
With Avengers: Doomsday now set for release on December 18, 2026, following a recent delay from its initial May 2026 slot to allow more time for production, the anticipation continues to build. The delay reflects Marvel’s commitment to delivering a polished multiversal epic. Whether or not Gambit’s universe ties directly to Monica Rambeau’s, the prospect of X-Men joining the MCU’s multiversal saga has fans on edge. Marvel Studios has a track record of delivering surprises, and Avengers: Doomsday could be the film that finally brings mutants into the spotlight. For now, fans are left to speculate and await official updates as the MCU’s ambitious Phase Six unfolds.
