UPDATE: Marvel’s Doomsday leak situation keeps snowballing. It started when a 72-second clip showing Doctor Doom unleashing Sentinels on the X-Men hit social media and was quickly judged authentic. Then Marvel’s failure to pull the footage sparked a wave of fan theories that the whole thing was an AI fake. The latest twist: a clearer, higher-quality version that’s tough to write off as fake — even if the Mjolnir moment everyone’s buzzing about isn’t the reveal fans were hoping for.
Alleged Avengers: Doomsday images have surfaced on X, showing what look like makeup tests, costume designs, and behind-the-scenes shots tied to the upcoming MCU crossover film.
Nothing is confirmed, but the photos are detailed enough that fans are treating them as potential early looks at the movie.
However, at the same time, some fans think they are fake and created using AI, and the X user responded to the backlash saying: “Like I said before, if you reach out to me with proof, I’ll delete what I’ve shared and tell people you’re legit. Until then, I’m just sharing what people send, and people can take it all with a grain of salt.”
Update: Following our article, the X user has deleted a number of the tweets containing the images.

Battle-Damaged Heroes and Villains
Several images show actors in heavy makeup with fresh wounds, scars, and bruising, including Tobey Maguire as Spider-Man and Channing Tatum as Gambit. The pictures include close-ups of bloodied faces, torn skin effects, and practical prosthetics.
One figure appears in blue-screen environments wearing a hooded green outfit with deep facial scarring, which is Robert Downey Jr.’s Doctor Doom. Another set shows Benedict Cumberbatch’s Doctor Strange and Chris Hemsworth’s Thor.

The images are inconsistent in quality, but assuming they are legit, they appear to come from a professional makeup environment, complete with studio lighting and application tools. The work looks gritty, textured, and closer to practical effects than digital edits.
Full Costume Teases
A handful of images show what look like full costume renders or suits being tested for screen. Images include Chris Evans, who appears to be Nomad, Lewis Pullman as The Sentry, and Sebastian Stan as the Winter Soldier.










X-Men Assemble
Images also feature the X-Men, including Patrick Stewart as Professor Charles Xavier, in what is reportedly his final acting role. Mystique is there, Cyclops, and a potential storyboard of the X-Men team.
