Marvel Studios is planning a major integration of the X-Men into the MCU with Avengers: Secret Wars, signaling a central, not just cameo, role for mutants in the Multiverse Saga.

To bridge old and new narratives, the film will feature actors from the original Fox X-Men films in the lead-up, delivering closure for prior stories while paving the way for future arcs in Avengers: Doomsday.

Directors Joe and Anthony Russo say Avengers: Secret Wars will draw on the 1984 and 2015 Secret Wars stories, aiming for a bold, expansive scale that matches the studio’s most ambitious projects.

Kevin Feige has outlined a reset for the MCU with a single timeline and a newly recast X-Men, backed by a ten-year plan to keep mutants central to the franchise.

Secret Wars is positioned as the definitive end to the Multiverse Saga, with shooting underway and a December 17, 2027 release window signaling a long-term, structural shift in how the MCU handles mutants.
