Marvelfans have long consideredDoctor Doomone 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.
As revealed by Marvel,One World Under Doom #5– written by Ryan North, with art by R.B. Silva – will align Doom with his greatest enemies to take on Dormammu, the interdimensional entity who rules over the dark dimension.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 villainin the MCU, Marvel movie fans are already familiar with the formidable Dormammu from his role as the antagonist ofDoctor Strange. In Marvel Comics, it is interesting that the two are going head-to-head now.

One World Under Doom #5– Written By Ryan North; Art By R.B. Silva; Available June 29, 2025 From Marvel Comics
Dormammu has always been one of themost dangerous mystical beings in the Marvel Universe, and inOne 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.
Should Doctor Doom fight Doctor Strange in Avengers: Doomsday?
Benedict Cumberbatch’s Doctor Strange has been confirmed for Avengers: Doomsday. I hope that we get to see him directly fighting Robert Downey Jr.’s Doctor Doom for a simple reason. With the Scarlet Witch dead and Loki holding the multiverse together, Strange is the only sorcerer powerful enough to warrant Marvel Studios showing Doctor Doom’s magical expertise from the comics. To defeat Strange, Doom would have to show how gifted a sorcerer he is, which would help make him more different from Tony Stark to fans, which is desperately needed after RDJ’s casting.
While Dormammu’s MCU counterpart appears much more tame, Season 3 of the animatedWhat If…?series suggests that he may have plans to enter the MCU in a much bigger way. In episode 4, fansheard 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.
