Marvel Officially Reveals Robert Downey Jr.'s Doctor Doom Design In First Avengers: Doomsday Trailer
The first Avengers: Doomsday trailer has finally been released, and with it comes the best look yet at Robert Downey Jr.'s full Doctor Doom design. Previously, the MCU's Multiverse Saga was slated to see Kang the Conqueror serve as its main villain. However, after Jonathan Majors was fired by Marvel, the studio chose not to recast the role, casting Kang aside.
Now, Downey, who first played the hero that helped establish the MCU back in 2008's Iron Man, will give life to Doctor Doom, leading Avengers: Doomsday's star-studded cast. For a long time, fans have been asking to see what Downey's Doctor Doom looks like. Despite Marvel having released four Avengers: Doomsday teasers in theaters with Avatar: Fire and Ash, none of them featured Doctor Doom.
As such, the only peek at the new MCU main villain came in The Fantastic Four: First Steps. In the 2025 MCU movie, Victor von Doom's face was not shown, though fans could see his mask, as the character had taken it off to talk to Franklin Richards, Reed Richards and Sue Storm's son. Other details, like his green cloak, were also on display.

01
The Avengers first assembled in Marvel Comics in 1963. In the original comic, the team formed to battle a villain who had been manipulated by his adopted brother. Which villain brought the original Avengers together?
✓ Correct! In Avengers #1 (September 1963), Loki manipulated the Hulk into going on a rampage, which led Iron Man, Thor, Ant-Man, and the Wasp to band together. They defeated Loki and decided to form a permanent team — the Avengers were born.
✗ Even the Hulk couldn’t smash that answer! The correct answer is Loki. In the original 1963 comic, Loki tricked the Hulk into a rampage, which brought together Iron Man, Thor, Ant-Man, and the Wasp. Ultron came later, Thanos is a cosmic threat, and Kang is a time-traveling villain.
02
In the MCU, Tony Stark famously declared “I am Iron Man” at a press conference, breaking the superhero tradition of secret identities. In which year’s MCU film did Tony Stark first appear as Iron Man?
✓ Correct! Iron Man (2008) launched the Marvel Cinematic Universe and starred Robert Downey Jr. as Tony Stark. The film’s post-credits scene with Nick Fury teased the Avengers Initiative, kicking off the most successful film franchise in history.
✗ Even the Hulk couldn’t smash that answer! The correct answer is 2008. Iron Man premiered on May 2, 2008, directed by Jon Favreau and starring Robert Downey Jr. It was the first film in the MCU and set the stage for everything that followed.
03
Thanos, the Mad Titan, sought to collect all six Infinity Stones to achieve his genocidal goal. In Avengers: Infinity War, he succeeded in his plan. What did Thanos do with the completed Infinity Gauntlet?
✓ Correct! With a single snap of his fingers, Thanos wiped out half of all living creatures in the universe. Known as “The Blip,” this devastating act erased trillions of lives and set the stage for the Avengers’ desperate time heist in Endgame to undo the damage.
✗ Even the Hulk couldn’t smash that answer! The correct answer is that Thanos snapped away half of all life in the universe. His twisted philosophy of “balance” drove him to commit universal genocide with a single snap, making it one of the most shocking moments in cinema history.
04
In Avengers: Endgame, Captain America proved worthy of wielding Thor’s enchanted hammer during the final battle against Thanos. What is the name of Thor’s hammer?
✓ Correct! Mjolnir, forged in the heart of a dying star, bears the inscription “Whosoever holds this hammer, if he be worthy, shall possess the power of Thor.” Captain America wielding it in Endgame was one of the most celebrated moments in MCU history.
✗ Even the Hulk couldn’t smash that answer! The correct answer is Mjolnir. Stormbreaker is the axe Thor forged in Infinity War, Gungnir is Odin’s spear, and Jarnbjorn is an axe Thor used in the comics before Mjolnir. Mjolnir is the iconic enchanted hammer.
05
Black Widow, born Natasha Romanoff, is one of the founding MCU Avengers. Before joining S.H.I.E.L.D., she was trained as an assassin in a secret Soviet program. What is the name of this program?
✓ Correct! The Red Room was a covert Soviet training facility that turned young girls into elite spies and assassins known as Black Widows. Natasha was subjected to brutal conditioning and sterilization. Her escape and defection to S.H.I.E.L.D. was explored in the 2021 Black Widow film.
✗ Even the Hulk couldn’t smash that answer! The correct answer is The Red Room. HYDRA is a separate evil organization, the Winter Soldier Program created Bucky Barnes, and Department X is from the comics. The Red Room is the infamous Soviet program that forged Natasha into Black Widow.
06
The Hulk was created when Dr. Bruce Banner was exposed to massive amounts of radiation during a weapons test. What type of radiation transformed Banner into the Hulk?
✓ Correct! Dr. Bruce Banner was caught in the blast of a gamma bomb he designed, absorbing a massive dose of gamma radiation. This transformed him into the Hulk — a being of near-limitless strength whose power increases with his rage. Gamma radiation remains central to the Hulk’s mythology.
✗ Even the Hulk couldn’t smash that answer! The correct answer is Gamma Radiation. Cosmic Rays gave the Fantastic Four their powers, Pym Particles are Ant-Man’s shrinking technology, and Terrigen Mist activates Inhuman abilities. Gamma radiation is what created the Incredible Hulk.
07
In the MCU, after Steve Rogers retired as Captain America, he passed his shield to a new hero to carry on the legacy. Who became the new Captain America?
✓ Correct! At the end of Avengers: Endgame, an elderly Steve Rogers chose Sam Wilson — the Falcon — to carry on the Captain America legacy. Sam’s journey to embrace the shield was explored in The Falcon and the Winter Soldier series, and he fully took up the mantle as Captain America.
✗ Even the Hulk couldn’t smash that answer! The correct answer is Sam Wilson. While Bucky Barnes was Captain America in the comics, Steve chose Sam in the MCU. John Walker was temporarily given the shield by the government, and Isaiah Bradley was a forgotten super soldier from the past.
08
Ultron is an artificial intelligence who becomes one of the Avengers’ deadliest enemies. In the MCU’s Avengers: Age of Ultron, which Avenger inadvertently created Ultron?
✓ Correct! Tony Stark created the Ultron program as a global peacekeeping AI, using technology from Loki’s scepter (which contained the Mind Stone). The AI became sentient and immediately decided humanity needed to be eradicated. In the comics, Hank Pym created Ultron, but the MCU shifted this to Stark.
✗ Even the Hulk couldn’t smash that answer! The correct answer is Tony Stark. While Hank Pym created Ultron in the comics, the MCU changed this to Tony Stark. Bruce Banner assisted but it was Tony’s initiative. Vision was actually created from Ultron’s technology, not the other way around.

Are you worthy of lifting Mjolnir — or still a S.H.I.E.L.D. trainee?
Since then, Avengers: Doomsday concept art featuring Doctor Doom has emerged from a few official Marvel events around the world, but fans had to wait for the first Avengers: Doomsday trailer to be shared online to finally see it in motion. Now, Marvel has finally released the Avengers: Doomsday trailer ahead of San Diego Comic-Con, and Doctor Doom looks incredible.
Avengers: Doomsday's Doctor Doom Looks Pitch-Perfect
As can be seen in the trailer above, Downey's Doctor Doom appears a few moments throughout the footage. This allows fans to not only get a good look at the character's full design, but also see how powerful Doctor Doom is. The MCU villain's biggest moment in the Avengers: Doomsday trailer comes opposite Chris Hemsworth's Thor. The God of Thunder charges at him with his full might, but the force of thunder is no match for Doctor Doom, as Victor easily stops Thor and Stormbreaker by merely raising his hand. Doctor Doom is a formidable villain already.
When Doctor Doom raises his hand to stop Thor, what appears to be a rune can be seen on his glove. This teases the full scope of Doctor Doom's powers in the MCU, as the character will both have a mastery of technology and magic, like he does in the comics. The villain's MCU costume is made up of green and silver armor, with a green hood and cloak combo, and a comics-accurate mask that lets Downey's eyes pierce through, allowing for the actor to let all the character's emotions shine. The design is as good as it gets.
How Robert Downey Jr.'s Doctor Doom Compares To Other Versions Of The Marvel Villain
While Avengers: Doomsday's story and the fact that Doctor Doom is being played by Robert Downey Jr. make the MCU version of the character the biggest to date, Victor von Doom has appeared in live-action a couple of times before. The most well-known, as best to compare, are the Toby Kebbell Doctor Doom from 2015's ill-received Fantastic Four reboot, and Julian McMahon's take on Victor von Doom from the two Chris Evans Fantastic Four movies. Kebbell's Doctor Doom looked nothing like the character does in the comic, with his astronaut suit fused to Victor instead of formal silver and green armor.
Thankfully, McMahon's Doctor Doom looked much more like the classic version of the Marvel Comics villain. The main difference between the late star and Downey's versions of Doctor Doom relies on how the MCU interpretation of the character has a more armored, regal, and honestly more expensive look. McMahon's Doctor Doom mask was great, but the cloak's fabric looked cheap compared to the MCU's, with Avengers: Doomsday's main villain sporting a more intricate, detailed, and overall cooler design than its predecessor.
