The reboot will unify the MCU into a singular timeline, allowing Marvel to recast legacy characters like Iron Man and Captain America. Feige compared the process to other iconic franchises: “They’re looking for a new James Bond. David Corenswet is the new Superman, and he’s been incredible. That’s always how it works”.

Marvel is set to recast characters in its upcoming X-Men franchise and Tony Stark, a character that became synonymous with Robert Downey Jr in the Marvel Cinematic Universe.

After the conclusion of Marvel's Secret Wars in 2027, the Marvel Cinematic Universe as we know it will be forever changed. "Reboot is a scary word,” Marvel boss Kevin Feige told Variety in a massive new interview.

"As we as we kick off phase six with with 'Fantastic Four,' and as everybody knows it ends with 'Secret Wars,'" Feige said.

Doomsday, due in 2026, will feature some Marvel figures who have been in the game even longer than Robert Downey Jr., as Iron Man. Patrick Stewart and Ian McKellen will return as Professor X and Magneto, having first played the roles for 2000’s X-Men movie.

Marvel Studios boss Kevin Feige has explained how Avengers: Secret Wars will change the Marvel Cinematic Universe going forward. The next few years will see another huge two-part team-up, with Doomsday and then Secret Wars. But what will come after that?

Kevin Feige has discussed Marvel's decision to replace Kang as the main villain of Avengers: Doomsday, and said talks with MCU legend Robert Downey Jr. to play Doctor Doom had begun before the departure of Jonathan Majors.

Can Doctor Doom beat Thanos? It's an increasingly common question among Marvel fans, with Robert Downey, Jr.'s Doctor Doom set to inherit the title of the greatest enemy of the Avengers from Josh Brolin's Mad Titan, the almighty Thanos.

According to a new rumor, Pedro Pascal’s Reed Richards / Mister Fantastic might not be the leader of the eponymous superhero team in the upcoming MCU movies Avengers: Doomsday and Avengers: Secret Wars. This comes after The Fantastic Four: First Steps director Matt Shakman indicated that Reed will lead the Avengers in those movies.
