Marvel has announced the return of some Marvel Cinematic Universe (MCU) stars in 2026's "Avengers: Doomsday," including Chris Hemsworth as Thor, Anthony Mackie as Captain America, Sebastian Stan as Bucky Barnes and Tom Hiddleston as Loki.

Part of the reason why fans are so certain about this theory is because concept art from Avengers: Doomsday leaked online which seemingly showed variants of She-Hulk and Hulk. Marvel security is notoriously tight, so the fandom is really running with what limited information it has about the project.
