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.

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

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.
