Leaked details surrounding the opening act of Avengers: Doomsday, slated for release on May 1, 2026, suggest a massive, reality-shattering battle that plunges viewers headfirst into the film's multiverse conflict. The sheer scale of this initial confrontation promises to be unlike anything seen before in the Marvel Cinematic Universe, immediately establishing the high stakes and multiversal scope of the movie.
Set video leaks from the London set reveal what appears to be approximately two dozen impact sites, hinting at a large-scale battle. The leaked concept art also suggests the appearance of God Emperor Doom. This early look at the film highlights the chaos and widespread destruction that audiences can expect as different factions and realities collide.
The catalyst for this multiversal war appears to be Doctor Doom, potentially portrayed by Robert Downey Jr. However, this isn't just another villainous plot; Doom seemingly believes he is trying to save the multiverse from incursions – events where parallel universes collide and destroy each other. His twisted logic dictates that the only way to ensure survival is to unify all universes into a single Battleworld under his rule.
This version of Doom may not originate from the Fantastic Four's universe, as fans know it. Instead, he may be a traveler, a survivor, or even a conqueror from another reality who views the infinite realities as a disease, with himself as the only surgeon qualified to excise the cancer. His plan reportedly involves collapsing all realities into a single, unified universe that he can rule with an iron fist.
Several factions are expected to be involved in this opening act, including the Avengers, the Thunderbolts, and the Wakandans from the primary MCU universe. The X-Men from the Fox Marvel universe are also rumored to make an appearance. Some reports indicate a team of "Invincible Avengers" will attempt to resolve an incursion between Earth-616 and the universe where Monica Rambeau is located in The Marvels. This team will supposedly include characters like Sam Wilson, Thor, Captain Marvel, Shang-Chi, Ant-Man (Scott Lang), Jennifer Walters, Yelena Belova, Bucky Barnes, Bruce Banner, Shuri, M'Baku, Namor, and the Fantastic Four.
The leakes suggest that the plot also involves Doctor Doom's kidnapping of Franklin Richards, the son of Reed Richards and Sue Storm, who is taken to a place called "Universe X". This act may be tied to Doom's plan to acquire the power needed to reshape the multiverse. It is also rumored that Doom discovers that Earth-616 is held together by anchor beings, one of whom is Peter Parker. This leads Doom to send his armies to hunt down Peter Parker to speed up the timeline's collapse.
The opening battle may also occur at Mansion X, according to some leaks, with concept art depicting a major conflict at that location. While specific plot details remain under wraps, these leaks paint a picture of a chaotic and action-packed opening for Avengers: Doomsday. The film promises to throw audiences into the deep end of the Multiverse Saga, setting the stage for a complex and potentially devastating conflict with Doctor Doom at its center.
