Is The Fantastic Four Setting Up a Cosmic War in the MCU?
Galactus Arrives! Fantastic Four Trailer Reveals Cosmic Chaos Ahead

Marvel’s much-anticipated Fantastic Four: First Steps trailer has not only revealed the iconic superhero team’s debut in the Marvel Cinematic Universe (MCU) but also dropped a bombshell: the introduction of Galactus, the Devourer of Worlds. With Galactus now firmly on the MCU's horizon, the question arises: is The Fantastic Four setting up a cosmic war that could change the landscape of the MCU forever?
A Glimpse into the Cosmic Threat
In the new trailer, Marvel introduces us to a retro-futuristic version of the 1960s, offering a nod to the original era of Fantastic Four comics. The story follows Reed Richards (Pedro Pascal), Sue Storm (Vanessa Kirby), Johnny Storm (Joseph Quinn), and Ben Grimm (Ebon Moss-Bachrach) as they come to terms with their newfound abilities after a spaceflight accident. Amid the personal challenges they face, the trailer hints at an even larger, far-reaching threat: Galactus.
Galactus is one of Marvel’s most powerful and destructive entities. His appetite for planets is insatiable, and he devours worlds to survive, consuming entire ecosystems and civilizations in his wake. First introduced in Fantastic Four #48 (1966), Galactus is a cosmic force of nature—far more powerful than any Earth-based villain. Given his vast strength and existential nature, it’s no wonder that Marvel fans are buzzing about his potential role in the MCU.
The Multiverse and a Cosmic War
What makes Galactus’ appearance particularly intriguing is the possibility of him being tied to the MCU’s multiverse storyline. Since the events of Avengers: Endgame and Doctor Strange in the Multiverse of Madness, the multiverse has become a focal point in the MCU. Galactus’ power to consume worlds could easily be tied to these realities—could he destroy one universe and push the Fantastic Four into another? Or, even more dangerous, could his actions set off a chain reaction that unleashes destruction on multiple worlds across the multiverse?
In the trailer, we see hints that the Fantastic Four might exist in a different timeline or universe altogether—possibly a 1960s reality that is different from the main MCU. If Galactus is involved, he could alter the course of the multiverse, leading to a cataclysmic cosmic war. The idea of worlds colliding or realities being shattered is not far-fetched, considering Galactus’ nature as a cosmic entity who operates on a scale far beyond that of the Avengers or even the Eternals.
A New Era for the MCU
The introduction of Galactus marks the beginning of a new, expansive phase for the MCU. While the Avengers faced more grounded, Earth-bound threats like Loki, Ultron, and Thanos, Galactus represents a new level of danger. His presence signals that Marvel is shifting its focus to a larger, more cosmic scope—one that will require more than just Earth’s mightiest heroes to confront. The Fantastic Four, who have long been a staple of Marvel’s cosmic stories, are uniquely positioned to lead the charge against such a devastating foe.
Given the power of the Fantastic Four’s combined abilities, they are among the few who could even stand a chance against someone like Galactus. However, their battles won’t be limited to one reality. The stakes are set to escalate as the multiverse and cosmic threats come into focus. Could The Fantastic Four: First Steps be laying the groundwork for a full-fledged cosmic war in the MCU?
Conclusion: The Calm Before the Storm?
With The Fantastic Four: First Steps set to hit theaters on July 25, 2025, it’s clear that Marvel is gearing up for something monumental. The introduction of Galactus as the villain is only the beginning. If the trailer is any indication, The Fantastic Four will set in motion a cosmic conflict that could shake the foundations of the MCU. Whether this leads to an all-out cosmic war, or whether it’s just the beginning of something bigger, one thing is certain: Marvel fans are in for a wild ride.
