Marvel Studios’ highly anticipated Avengers: Doomsday movie has received another rumor, teasing new details about Doctor Doom’s potential allies. The next Avengers movie arrives in theaters on December 18, 2026, followed by Avengers: Secret Wars’ debut on December 17, 2027.

What’s the new Doctor Doom update for Avengers: Doomsday?

The latest rumor is from James Mack on X, who claimed that Avengers: Doomsday will feature a “group of several Dooms,” including a “muscular Doom” with a physique like the Hulk. This comes after a previous report suggested that Doctor Doom’s rumored team might be bigger than expected since the fan-favorite villain will reportedly have men and women masked sidekicks. At the moment, it remains unclear if Doctor Doom’s potential allies would be “a cult of characters” with Doom masks or if they are “actual Doom variants.”

there is indeed a group of several “Dooms” in AvengersDoomsday, but I don’t know if it’s a cult of characters masked as Doom or actual Doom variants
Besides the female versions that leaked, there’s also a big, muscular Doom. He LOOKED like a masked Hulk, but I can’t say for sure
