What the Leaked Avengers: Doomsday Footage Reveals About Doctor Doom and the X-Men

How Doctor Doom Commands the Sentinels in the Leak

The central reveal from the circulating clip is Doctor Doom’s chilling control over a legion of Sentinels. The footage depicts Doom activating the towering mutant-hunting robots, which are traditionally programmed to target mutants . However, in this scene, he is seen wielding them as his personal weapons against a wider array of heroes.

The method of control appears to be a fusion of technology and sorcery. Several reports describe Doom casting mystical green runes from his hands to hijack the Sentinels, overriding their base programming and bending them to his will . This aligns with classic depictions of Doom’s character, who is a master of both science and magic.

The Sentinels are then shown rampaging through a combined force of heroes . The battle is reported to take place at or around the X-Mansion, with the footage showing Doom’s attack decimating the iconic school grounds .

Characters Spotted in the Battle Scene

The pixelated quality of the leak has not stopped fans and commentators from identifying a massive roster of characters in the fray. The heroes facing off against Doom and his Sentinel army include a crossover of iconic MCU and returning Fox-era characters . Those visible in the footage, as described by multiple sources, include:

• Thor, wielding Stormbreaker
• Steve Rogers, summoning Mjolnir
• Sam Wilson as Captain America
• Yelena Belova
• Mr. Fantastic (Reed Richards)
• Shang-Chi
• Gambit
• Mystique
• Nightcrawler
• Cyclops

At one point, Thor can reportedly be heard calling out a name that begins with "Sto…," which many believe to be a call for Storm, hinting at her possible involvement .

Fox-Era X-Men Officially Return in Comic-Accurate Costumes

While the leaked footage has dominated fan discussion, the return of the original X-Men cast is not a rumor. Marvel Studios officially confirmed the casting earlier in 2026 through a teaser and a chair-reveal sequence, showcasing the actors with their iconic character symbols . The following six Fox-era actors are the centerpiece of this return :

• Patrick Stewart as Professor Charles Xavier / Professor X
• Ian McKellen as Erik Lensherr / Magneto
• James Marsden as Scott Summers / Cyclops
• Rebecca Romijn as Raven Darkhölme / Mystique
• Kelsey Grammer as Dr. Hank McCoy / Beast
• Alan Cumming as Kurt Wagner / Nightcrawler

Though they are the core group, reports also indicate that other actors, such as Famke Janssen (Jean Grey), Halle Berry (Storm), and Hugh Jackman (Wolverine), are expected to appear but have not been part of the official announcement .

Perhaps the most celebrated detail is the costume design. After years of fan calls for the X-Men to abandon the black leather aesthetic of the early 2000s films, the team will finally wear bright, comic-accurate suits. The designs are heavily influenced by a 90s Jim Lee aesthetic, reflecting the popular style of X-Men '97 . James Marsden has publicly confirmed that his Cyclops costume is directly based on the character's classic look from the comics .
