First Steps, I am convinced that Doctor Doom will be Avengers: Doomsday 's main character. The ending of The Fantastic Four: First Steps did not do much to actively set up Avengers: Doomsday, with the team remaining in their contained universe after defeating Galactus.

First Steps line up with the end of Thunderbolts* as the franchise builds to the release of the epic Avengers: Doomsday in December 2026? CinemaBlend's own Jeff McCobb recently broached that subject in an interview with director Matt Shakman during the Los Angeles press day for the new 2025 movie,
