Marvel officially confirms Avengers: Doomsday's cast have always been the Fantastic Four. The Fantastic Four: First Steps' July 2025 release date raised the question of how Marvel will integrate them into the MCU's main timeline in order to pit them against Doom alongside the Avengers.

During Marvel Studios' Avengers: Doomsday cast announcement, Marvel Studios has confirmed the return of all four of the MCU's Fantastic Four: Sue Storm actor Vanessa Kirby, Ben Grimm actor Ebon Moss-Bachrach, Johnny Storm actor Joseph Quinn, and Pedro Pascal's Reed Richards. All four Fantastic Four heroes will return only one year after their introduction in 2025's The Fantastic Four: First Steps. Check out Marvel's official Avengers: Doomsday cast announcement:

The early confirmation of the Fantastic Four's return suggests they will take center stage in Avengers: Doomsday.
