Phase 6’sAvengers: Secret Warscould recover one amazing multiversal-themedMCUscene that has been scrapped twice already. The Multiverse Saga has allowed the MCU to create scenarios that would be unimaginable without the concept of alternate timelines. Recent releases likeLoki,Spider-Man: No Way Home,Doctor Strange in the Multiverse of Madness, andDeadpool & Wolverinehave brought together different portrayals of characters from previous franchises likeFox’sX-Menmovie universeand Sony’sSpider-ManandThe Amazing Spider-Manmovies. The Multiverse Saga has even introduced multiversal mutants in the MCU even beforethe MCU’s ownX-Menmoviearrives.
Everything in Phases 4 and 5 points toward the conclusion of the Multiverse Saga inthe Russo Bros.' upcomingAvengers: Secret Wars,which may see Robert Downey Jr.’s Doctor Doom face all the heroes from all across the Sacred Timeline with the fate of the multiverse at stake, similarly to the events of Marvel Comics' 1985 and 2015Secret Warsstorylines. Therefore,Avengers: Secret Warscould be the last time the MCU will be able to justify ambitious multiversal crossovers before Phase 7 launches a new saga set in a streamlined timeline.

Otherwise, Battleworld’s creation could force several heroes to escape Doctor Doom through collapsing timelines, which could include those seen in previous MCU and non-MCU Marvel movies and shows. A similar event happened in the 2015Secret Warscomics, where some heroes and villains escaped incursions aboard a Life Raft.

Following some enormous revelations for the future of the Avengers at San Diego Comic-Con, the cast of Secret Wars is beginning to come together.
Avengers: Secret Wars' multiversal Time Heist would wrap the Multiverse Saga with a final dose of nostalgia. OnceAvengers: Secret Warslaunches a new saga, Phase 7 could focus on introducing new characters like the X-Men. At that point, a limited number of references to previous movies and franchises would prove that the MCU doesn’t need to rely on nostalgia to please fans. This change could entail a soft-reboot that streamlines the MCU’s timeline and leaves the concept of the multiverse behind.
