Rumors: MCU X-Men Reboot To Introduce One of the Most Important X-Men Villains

In March 2019, Marvel Studios regained the film rights to X-Men, Fantastic Four, and Deadpool after Disney acquired Fox for $71.3 billion. These characters are set to join the MCU. In October 2020, the ‘X-Men’ and ‘Fantastic Four’ films were renamed “Marvel Legacy films” on Disney+. Notably, Patrick Stewart reprised his role as an alternate Professor X in ‘Doctor Strange in the Multiverse of Madness,’ and Kelsey Grammer returned as Beast in ‘The Marvels.’ ‘Deadpool & Wolverine,’ a sequel to ‘Deadpool 2,’ will introduce Deadpool and Wolverine, played by Ryan Reynolds and Hugh Jackman, respectively, into the MCU continuity.

A new X-Men film, aiming to reboot the franchise within the MCU, began development in September 2023. Rumors of its development surfaced as early as 2021, with Kevin Feige involved. However, updates on the project have been scarce. According to Daniel Richtman, the MCU plans to incorporate Mister Sinister, one of the most popular X-Men villains, into the reboot.

Mister Sinister, also known as Nathaniel Essex, is a supervillain in the Comics. He was introduced by writer Chris Claremont and first appeared as the enigmatic leader of the Marauders in ‘The Uncanny X-Men’ #212. His full debut came in ‘The Uncanny X-Men’ #221.

Born in Victorian London, Mister Sinister was originally a human scientist influenced by Charles Darwin’s theories. His obsession with creating a superior race led him to seek out alien Celestial technology, which transformed him into an ageless being with superhuman abilities after an encounter with the mutant villain Apocalypse.
