Marvel Studios’ upcoming film, The Fantastic Four: First Steps, introduces its two primary villains—Galactus and Mole Man. Not surprisingly, this exciting reveal has ignited widespread fan discussions about the Fantastic Four Villains Confirmed and the highly anticipated cinematic debut of Marvel’s first family in the Marvel Cinematic Universe (MCU).
The Fantastic Four: First Steps brings Marvel’s iconic team to the MCU with thrilling energy. Notably, Matt Shakman directs this highly anticipated film, which is set to debut on July 25, 2025, as the centerpiece of Phase 6. As a result, fans can look forward to cosmic stakes, stunning visuals, and an intense clash with the Fantastic Four Villains Confirmed. Moreover, the stellar cast and gripping storyline strive to redefine the team’s legacy on screen, offering an unforgettable cinematic experience.
Galactus – The Cosmic Devourer Among the Fantastic Four Villains Confirmed
Galactus, a cosmic planet-destroyer, emerges as a key antagonist in The Fantastic Four: First Steps. Notably, Ralph Ineson brings the character to life through CGI and motion capture, creating a colossal threat. Moreover, leaked footage reveals Galactus on an alternate Earth, while Silver Surfer ominously warns of impending doom. Consequently, the story delves into whether the Fantastic Four can save their planet from destruction, ultimately setting the stage for connections to Avengers: Doomsday.

Mole Man – The Subterranean Ruler
The second major villain is Mole Man, portrayed by an actor yet to be confirmed; however, rumors strongly suggest Paul Walter Hauser. Mole Man, whose real name is Harvey Rupert Elder, holds a significant place in Marvel history as the first villain the Fantastic Four ever encountered in the comics.

In a recent interview with Omelete at CCXPMX 25, actor Joseph Quinn teased Mole Man’s role in the movie:
“There’s also Mole Man, who’s wonderful in it. But Galactus is the big bad.”
Mole Man’s backstory is fascinating and includes several key elements:
- A nuclear engineer and conspiracy theorist
- A believer in the Hollow Earth theory
- Ruler of the Moloids, creatures created by the Deviants
More Villains in Fantastic Four?
Alongside Galactus and Mole Man, Fantastic Four is now rumored to introduce yet another villain — Red Ghost (Ivan Kragoff), a Russian scientist determined to replicate the team’s origin event. This addition could also help set up connections to Avengers: Doomsday, further integrating the Fantastic Four into the larger Marvel Cinematic Universe.
While the filmmakers have stated that Robert Downey Jr. will not appear as Doctor Doom, fans remain skeptical. As the Fantastic Four’s most iconic villain, many believe Marvel might be saving his reveal for a major twist.
With multiple villains and major crossover potential, the film is shaping up to be an action-packed and thrilling experience fans won’t want to miss.
A Villainous Team-Up?
As Mole Man unleashes attacks on the surface world and Galactus threatens planetary extinction, the Fantastic Four confront unparalleled challenges. Moreover, the movie’s dynamic plot and impressive villain roster promise to deliver a thrilling start to Phase 6.
