Marvel’s Avengers: Doomsday is now in production, and we’ve received some important leaked plot details. According to a report from James Mackwl on X, members of the design team are working on concept art related to a major battle at Mansion X. One piece of artwork is titled “Invincible Avengers.”
In Avengers: Doomsday, this team is tasked with resolving the Incursion between two worlds and rescuing Monica Rambeau. These heroes, along with other characters from that universe, later protect Loki at the Citadel after finding the TVA and Doctor Doom’s plan.
The team members include Sam Wilson, Thor, Captain Marvel, Shang-Chi, Ant-Man (Scott Lang), Jennifer Walters, Yelena Belova, Bucky Barnes, Bob, Bruce Banner, Shuri, M’Baku, Namor, and the Fantastic Four, who join the mission because Doom kidnapped Franklin Richards, the son of Reed Richards and Sue Storm and took him to a place called “Universe X.”
Meanwhile, John Walker, Ghost, and Red Guardian remain on Earth-616 alongside other Avengers to protect the planet from an unknown invasion. The remaining Thunderbolts unite with Wakanda, Talokan, and the sorcerers led by Wong to help defend Earth.
During production, a few leaked images appeared online showing a destroyed Sentinel in front of the X-Mansion. It is reported that Downey Jr.’s Doctor Doom will be using Sentinels to fight the X-Men in Avengers: Doomsday.
Directed by Russo brothers from a screenplay by their longtime collaborator, Stephen McFeely. Newton Thomas Sigel (Bohemian Rhapsody, X-Men: Days of Future Past) will be the cinematographer.
