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.

Rebecca Romijn, 52, will officially return as Mystique. She starred as the shapeshifter in “X-Men, X2: X-Men United,” “X-Men: The Last Stand” and “X-Men: First Class and Joan in The Punisher.”
