Avengers Doomsday is currently shooting just outside of London with Robert Downey Jr returning to the MCU as the villainous Doctor Doom.
Marvel Studios has confirmed the Avengers will team up with the Thunderbolts (New Avengers), Fantastic Four and X-Men in the blockbuster set for release around Christmas 2026.
Take it all with a pinch of salt, but a plot synopsis leak is doing the rounds online and it sounds rather feasible.
It reads: “Shuri is the one who discovers the Incursions. While detecting anomalies in the fabric of reality and investigating the multiverse, she realizes that different universes are colliding with each other. Using a hologram (like in the Shang-Chi post-credits scene), she shares her findings with Sam, Wong, Bruce Banner, and Carol Danvers, warning them about the imminent threat.
“Meanwhile, the events of the Fantastic Four’s arrival on Earth-616 take place. The Thunderbolts/New Avengers are the first to encounter them. Reed Richards reveals that Doctor Doom has kidnapped his son, Franklin, and also mentions Galactus, who previously tried to capture Franklin because of his immeasurable powers. Bucky, unsure how to handle the situation with Doom, goes to seek advice from Sam.
“Later in the story, Shuri gathers Sam, Wong, Banner, and Carol in person in Wakanda. In a large meeting room, Thor, Bucky, Yelena, M’Baku, Namor, and the Fantastic Four are also present. Shuri reveals that a specific universe is dangerously approaching Earth-616. During the conversation and while analyzing the situation, she detects the energy signature of someone from Earth-616 trapped in the approaching universe. Carol deduces it’s Monica Rambeau and becomes even more motivated for the mission.”
It adds: “At the same time, Reed Richards uses Wakandan technology to track Franklin and discovers that he too is in this parallel universe, and he also deduces that Doctor Doom is there with him. Thus, they come up with a plan with three objectives: to stop the Incursion and save Earth-616, to rescue Monica Rambeau, and to defeat Doctor Doom by saving Franklin Richards. To open a portal to this parallel universe, Wong calls America Chavez, her only role in the film. Everyone unites for this mission: the Avengers led by Sam, part of the Thunderbolts/New Avengers (not all of them), the Fantastic Four, Shuri, M’Baku, and Namor. Wong stays behind on Earth. From that point on, it’s Earth-616 versus the Earth where the X-Men reside, and they soon discover that it’s all part of an even bigger plan involving Doctor Doom, the TVA and Loki.”
Scooper Daniel RPK claims the leak is fake, but some are more convinced than others.
Avengers Doomsday hits cinemas on December 18, 2026.
