In the Marvel Cinematic Universe, Loki, played by Tom Hiddleston, is notably absent from Avengers: Age of Ultron, marking him as the only major character missing from this installment. Despite having been a central figure in The Avengers and making appearances in Avengers: Infinity War and Endgame, Loki's role was cut from Age of Ultron due to confusion during test screenings, where audiences mistakenly believed he was controlling Ultron. Although his absence did not impact the film's plot, it has become a point of interest among fans. Loki is set to make a significant return in Avengers: Doomsday, where he has transformed into the God of Stories and protector of the multiverse. This evolution positions him as a crucial character in the ongoing Multiverse Saga, especially with the looming threat of Doctor Doom. His return is highly anticipated as it promises to reintegrate him into the Avengers narrative after his limited roles in previous films.
