Avengers: The Kang Dynasty will feature a mostly new team of MCU heroes according to Disney CEO Bob Iger. Marvel Studios announced plans for more Avengers movies last year, three years after the release of Avengers: Endgame. Directed by Destin Daniel Cretton (Shang-Chi and the Legend of the Ten Rings) and written by Michael Waldron (Ant-Man and the Wasp: Quantumania), Avengers: The Kang Dynasty is set for release in 2025. Audiences have seen the MCU introduce several new characters during the Multiverse Saga who could join established heroes as part of the next Avengers team, but no members have been officially announced by the studios.
