Marvel Studios has released a spectacular new special look at Avengers: Doomsday, revealing the clearest picture yet of Robert Downey Jr.’s transformation from the face of Iron Man into one of the most dangerous villains in Marvel history.
The new footage debuted during D23 before being released online, and this time Doctor Doom is unmistakably at the centre of the story.
Downey plays Victor von Doom, a brilliant and enormously powerful figure whose arrival threatens not simply one team of superheroes, but multiple realities.
The footage suggests that Doom’s motivations are rooted in tragedy.
Sue Storm speaks about the man Victor once was, while glimpses of his past hint at devastating personal loss that may have reshaped his view of the multiverse and the people living within it.
But whatever sympathy may exist for the person Doom used to be, the man confronting Marvel’s heroes now appears almost impossibly dangerous.
One of the special look’s biggest moments brings Doom face-to-face with Thor.
Chris Hemsworth’s God of Thunder attacks with Stormbreaker, only for Doom to stop the assault with shocking ease.
It is a simple demonstration of power, but an important one.
Thor has spent years fighting gods, monsters, Thanos and some of the strongest beings in the MCU. Showing Doom capable of standing against him immediately establishes just how serious the new threat has become.
The footage becomes even more alarming when Doom appears to command an army of Sentinels — the enormous machines created to hunt mutants.
Their appearance finally brings one of the most recognisable elements of the X-Men universe directly into Marvel Studios’ biggest crossover story.
And the X-Men themselves are coming with them.
Patrick Stewart returns as Charles Xavier, Ian McKellen as Magneto and James Marsden as Cyclops, joining a film that brings characters from the previous X-Men movies into direct contact with the MCU and the Fantastic Four.
That crossover is no longer simply a collection of nostalgic appearances.
The special look suggests that the collision between different Marvel realities will form the actual structure of the story.
Pedro Pascal’s Reed Richards is shown confronting Doom, establishing a relationship that comic-book readers have expected since the Fantastic Four entered the MCU.
In Marvel mythology, Reed Richards and Victor von Doom are two of the most brilliant minds on Earth — and two men whose rivalry has repeatedly placed entire worlds in danger.
Their confrontation in Doomsday therefore carries considerably more weight than a conventional hero-versus-villain encounter.
The Fantastic Four are also bringing their own universe into the crisis.
Vanessa Kirby returns as Sue Storm alongside Pedro Pascal as Reed Richards, Joseph Quinn as Johnny Storm and Ebon Moss-Bachrach as Ben Grimm.
Elsewhere, the Avengers themselves are assembling again.
Anthony Mackie returns as Sam Wilson’s Captain America, Chris Hemsworth as Thor and Paul Rudd as Ant-Man, alongside characters from Wakanda and the New Avengers.
But one of the film’s biggest surprises remains Chris Evans.
After Steve Rogers seemingly completed his journey at the end of Avengers: Endgame, Evans is officially returning as the original Captain America.
The exact circumstances surrounding Steve’s return remain deliberately mysterious, but the special look reinforces that his story will have a meaningful place in the conflict rather than functioning simply as a cameo.
Hayley Atwell is also returning as Peggy Carter.
That combination immediately raises questions about what happened after Steve travelled through time at the end of Endgame and whether his decision to remain with Peggy may somehow connect to the multiversal instability now threatening reality.
The film is once again directed by Joe and Anthony Russo, who previously guided the MCU through Captain America: The Winter Soldier, Captain America: Civil War, Avengers: Infinity War and Avengers: Endgame.
Their return places Doomsday firmly in the lineage of Marvel’s largest crossover events.
But the scale is now considerably greater.
Infinity War brought together separate corners of one cinematic universe.
Doomsday appears to be bringing together separate universes.
The Avengers, Wakandans, New Avengers, Fantastic Four and X-Men are all moving towards the same conflict, while Doctor Doom appears to understand the multiverse — and perhaps its weaknesses — better than almost anyone opposing him.
The new footage also makes clear that Robert Downey Jr. is not simply playing an evil version of Tony Stark.
His posture, voice and physical presence are deliberately different, presenting Doom as an entirely separate character despite the unavoidable significance of Downey returning to Marvel after defining the MCU’s first eleven years.
That casting decision creates an additional emotional problem for the heroes who remember Tony Stark.
They may know intellectually that Victor von Doom is another man.
But seeing Tony Stark’s face behind the mask of their greatest new enemy could make that distinction considerably harder to accept.
And Doom seems unlikely to care.
The special look ends by firmly establishing his identity and power, positioning him as the figure around whom the next stage of the Marvel Cinematic Universe will revolve.
The film will also directly set up Avengers: Secret Wars, scheduled to follow in 2027.
If Doomsday represents the collapse of the boundaries separating Marvel’s different realities, Secret Wars may ultimately reveal what survives after those boundaries disappear completely.
For now, Marvel is keeping many of the answers hidden.
But the latest footage makes one thing increasingly clear.
The Avengers are not simply facing another villain.
They are facing Doom.
Avengers: Doomsday arrives exclusively in cinemas on December 18, 2026.
