Marvel spent years establishing Thanos as the main villain of The Infinity Saga, and Avengers: Infinity War ultimately delivered on that build-up. Now, Marvel Studios is hoping to achieve the same success with Doctor Doom, who will officially join the Marvel Cinematic Universe in Avengers: Doomsday. A major point of discussion is who will play him. Marvel’s decision to cast Robert Downey Jr. as Doctor Doom is surprising and unique, considering how famous he is for his role as Iron Man in the MCU.
Rumors suggest Marvel Studios might link Doctor Doom to Tony Stark’s past, and while different versions of the story exist, Doctor Doom is usually portrayed as the main antagonist. Fans have been eager to see a proper adaptation of this iconic Marvel villain, as previous Fantastic Four movies haven’t quite captured his essence. The upcoming Avengers: Doomsday aims to show why Doctor Doom is considered one of the greatest villains in comic book history. Some might think he’s too much of a leap to be more dangerous than Thanos, but the comics provide plenty of evidence to support that idea – and that history will be important if Avengers: Doomsday wants to surpass previous Marvel films.
Thanos’ Power Peak With the Infinity Stones
Before obtaining the Infinity Stones, Thanos was already a formidable and strategic warrior. But his pursuit of the Stones amplified his power to an unimaginable degree, ultimately allowing him to eliminate half of all life in the universe. Despite this incredible power, it’s important to remember that the Infinity Stones are the source of his strength – it’s not inherent to him, and therefore isn’t permanent.
Thanos remains a powerful enemy, as demonstrated in Avengers: Endgame, but he’s much less of a threat without the Infinity Gauntlet. After using the Stones to achieve his goal, he nearly dies. While Thanos sought ultimate power with the Stones, Loki Season 1 revealed that such power is limited when dealing with the vastness of the multiverse, suggesting a need for an even stronger villain.
Doctor Doom reaches his most powerful state in the 2015 Secret Wars comic, building his own reality after taking the Beyonders’ abilities. However, Doom has consistently demonstrated he doesn’t need the Beyonders’ power to be formidable. Ultimately, though, Doctor Doom’s highest level of power surpasses anything Thanos ever achieved.
Doctor Doom Is Smarter and More Ambitious Than Thanos
The comic book version of Thanos wants to please Death by bringing balance to the universe. But the Marvel Cinematic Universe presented a more realistic and nuanced Thanos, making him a complex villain. He’s certainly not unintelligent, and unlike many villains, he actually succeeds in his plan. Doctor Doom, however, is a different story.
Doctor Doom is incredibly intelligent, rivaling the brightest minds in the Marvel Universe like Reed Richards and Tony Stark. This intelligence lets him master both technology and magic, areas previous Fantastic Four movies didn’t fully show. Unlike Thanos, Doom has much bigger goals; his creation of Battleworld in Secret Wars is far more ambitious than anything Thanos attempts in Avengers: Infinity War.
Doctor Doom will be introduced in Avengers: Doomsday, but will first make a quick appearance during the credits of The Fantastic Four: The First Steps. Because Avengers: Secret Wars is planned soon after, this suggests the MCU’s version of Doctor Doom might be presented as a powerful and established villain from the start.
Rumors suggest Doctor Doom might initially team up with the Avengers in the upcoming film. This would fit his pattern of cleverly manipulating situations to get what he wants. While Thanos’s motivations in the Marvel Cinematic Universe are strong, Doctor Doom, in the comics, is even more ruthless and determined to achieve his aims of control and order.
Doctor Doom Becomes a God at One Point and Manipulates the Multiverse
Marvel Studios is planning a new attraction at Avengers Campus that will explore a reality where Thanos succeeded in wiping out most of the universe and has been ruling ever since. This alternate timeline could also be how future movies like Avengers: Doomsday or Secret Wars bring Thanos back. However, even this powerful version of Thanos wouldn’t be as formidable as Doctor Doom.
While Thanos aims for kingship, Doctor Doom achieves godhood, reshaping the entire universe into Battleworld based on his vision. As God Emperor, Doom has Doctor Strange as an ally and leads a powerful army of Thors. He also continues to rule his native country, Latveria, and commands its military forces.
The newest stories in the Marvel Cinematic Universe have focused on the multiverse, and previously introduced Kang the Conqueror as a major villain. However, after Jonathan Majors was let go by Marvel Studios, the storyline shifted. Kang is incredibly powerful, capable of controlling different universes, and Doctor Doom is another villain on that same level.
Thanos’s actions are limited to a single universe, but Doctor Doom’s scope is much larger. In the comics, specifically Secret Wars, he merged the 616 and Ultimate universes. It’s likely the Marvel Cinematic Universe (MCU) will follow suit, with Doctor Doom potentially uniting various universes, including those featuring the X-Men from Fox’s films and Tobey Maguire’s Spider-Man.
Doctor Doom Has Defeated Thanos Before
Doctor Doom and Thanos are well-known for battling the Avengers and other heroes in comic books, but they’ve also clashed with each other on several occasions.
In the Infinity Gauntlet comic book arc, Doctor Doom joined forces with both heroes and villains to fight Thanos, but Thanos ultimately won.
Without the power of the Infinity Gauntlet, Thanos is surprisingly vulnerable. Doctor Doom manages to defeat him decisively in the comics by breaking his spine, turning him to dust. Many fans hope this dramatic showdown will be recreated in future Avengers films.
A fight between Doctor Doom and Thanos wielding the Infinity Gauntlet would be amazing to see on film, and it would really demonstrate just how powerful Doom is. While this showdown hasn’t happened in the comics, the Marvel Cinematic Universe has the opportunity to show audiences the full extent of Doom’s threat.
The Marvel Cinematic Universe has achieved incredible things, and a major highlight is the character of Thanos. It’s tough for any villain to meet high expectations, but Marvel Studios didn’t just recreate Thanos from the comics—they made him even more complex and interesting.
To make Doctor Doom a truly memorable villain, Marvel Studios needs to build him up like they did with other successful characters. Fortunately, he’s already widely considered one of Marvel’s best villains, and the movies can directly adapt some iconic comic book moments to achieve this.
Unlike Thanos, who had years of development in the Marvel Cinematic Universe, Doctor Doom will be introduced without that same foundation. The upcoming Avengers: Doomsday movie will need to quickly establish Doctor Doom’s character and make him a truly compelling villain – potentially the greatest the franchise has seen. But a villain doesn’t have to be the most powerful to be memorable.
The Joker doesn’t win by overpowering Batman in a fight; he challenges what Batman believes in. Doctor Doom could be an even more formidable villain, not just physically, but by threatening the heroes’ core beliefs and becoming the most powerful villain the Marvel Cinematic Universe has ever seen. This level of threat is important because future Avengers movies are expected to be massive blockbuster events, and they’ll need a villain to match.
