Doctor Doom one of the most powerful villains in the Marvel Universe, but his latest arc seems to challenge that. In the series, Doom is forced to seek assistance from the Avengers due to a threat far beyond his capabilities. The fact that he even requested assistance shows how dangerous this threat is, but what's most surprising is that it has a familiar name.

Despite Doom’s overwhelming power as Emperor, Dormammu is presented as a greater cosmic threat, which is a fascinating turn of events.

While Victor is the next major villain in the MCU, Marvel movie fans are already familiar with the formidable Dormammu from his role as the antagonist of Doctor Strange. In Marvel Comics, it is interesting that the two are going head-to-head now.

Dormammu has always been one of the most dangerous mystical beings in the Marvel Universe, and in One World Under Doom #5, this is set to be made even clearer, as the interdimensional deity becomes the major antagonist of the crossover. When he arrives to challenge Doom, he is forced to seek help from Earth’s heroes, which should serve as a wake-up call for both Doom and the readers; as teased by Marvel, Doom’s struggle to survive in the face of Dormammu’s attack emphasizes the difference in their respective abilities, making Dormammu’s power undeniable.

While Dormammu's MCU counterpart appears much more tame, Season 3 of the animated What If...? series suggests that he may have plans to enter the MCU in a much bigger way. In episode 4, fans heard of Kaecilius's plans to retrieve a host body for Dormammu, meaning that the ruler of the dark dimension has the power to posesses and puppeteer others, meaning he could be a potent threat in the future. If the MCU continues to build on this, it could even position Dormammu as the grand string puller behind any major event in the MCU.

Despite the looming power of Dormammu, His willingness to forces with Earth’s Mightiest Heroes, despite his pride, proves that he’s still one of the most formidable figures in the Marvel Universe.

It will be fascinating to see how the MCU chooses to approach the power scaling of these two iconic villains in future films. While Dormammu undoubtedly outmatches Doctor Doom in of raw strength and cosmic power, Doom's tactical brilliance and unmatched ability to adapt to nearly any situation make him a formidable opponent in his own right. Seeing him align with his enemies to take down anyone is a massive testament to their power, so fans will be on the edge of their seats, when Marvel's spectacular Doctor Doom vs. Dormammu showdown reaches its climax.
