Could Chris Evans’ Captain America Save the Multiverse in Avengers: Doomsday?
The theory ties into a key event from “Avengers: Endgame”, when Steve Rogers undertook a journey to restore the Infinity Stones to their original timelines following the Time Heist. This significant endeavor aimed to prevent multiple realities from becoming uncontrollable, as the Ancient One (portrayed by Tilda Swinton) informed Bruce Banner (Mark Ruffalo). Instead of returning to the present after finishing his task, Rogers opted to stay in the past and spend his days with Peggy Carter (Hayley Atwell). Although this decision offered a heartwarming ending to Captain America’s tale, the long-term effects of his choice on time travel were not further developed within subsequent MCU films.
