Various reports have already signalled that the initial announcement – revealing everyone from Chris Hemsworth’s Thor to Patrick Stewart’s Professor X will be in Doomsday – is just the start of the cast rollout,

Marvel in an all-day stunt spent 5 and a half hours revealing the names of 27 members of the cast of 'Avengers: Doomsday.'

Avengers: Doomsday is expected to deal with characters across parallel universes, meaning actors can play various roles. Though Chris Evans exited the franchise as Steve Rogers, the original Captain America, in Avengers: Endgame, there have been reports he’ll return as another character in the 2026 movie.
