Marvel Studios has unveiled the final trailer for The Fantastic Four: First Steps, delivering long-awaited glimpses of Julia Garner’s Silver Surfer and Ralph Ineson’s Galactus. While the trailer stops just short of revealing Galactus’ full face—despite earlier leaks in promotional merchandise—it powerfully conveys the sheer scale and terrifying presence of this cosmic devourer. More than just atmosphere, the footage hints at a crucial plot point: exactly how Galactus intends to consume Earth. A single, pivotal scene may hold the answer.
How Will Galactus Consume the Earth?
One of the most cryptic moments in the trailer showcases a massive, arcing structure rising over Paris. Composed of intricate, glowing metal beams, the device appears to be channeling energy skyward. Is this one of Reed Richards’ scientific marvels? Unlikely. Instead, this structure is almost certainly part of Galactus’ planet-consuming machinery.
This is likely an Elemental Converter—a device rooted in Marvel Comics lore. Though Galactus is a being of immense power, he cannot simply devour a planet whole. Instead, he relies on Elemental Converters to break down a planet’s matter and organic composition into a form of energy he can consume. These machines are deployed across the globe, initiating a systematic conversion process that transforms entire worlds into nourishment.
The trailer strongly suggests that Galactus and his herald, the Silver Surfer, have planted these devices at key locations on Earth. The Paris structure is likely just one of many. If that’s the case, then the Fantastic Four’s best chance to save their home planet lies in dismantling these converters before the process reaches its final stage. Cutting off Galactus’ food source could be their only hope of stopping the inevitable.
While Galactus has, on rare occasions, been depicted literally consuming planets, this method is not his standard approach. The use of the Elemental Converter aligns with his established modus operandi—methodical, unstoppable, and devastatingly efficient.
So, will the Fantastic Four succeed in stopping Galactus? That remains one of the biggest questions heading into First Steps. Their failure could even explain their appearance in the post-credits scene of The New Avengers, where they’re seen fleeing to a new universe. Is Earth’s destruction at the hands of Galactus the catalyst for their MCU crossover? If so, it would mark a bold and emotionally charged conclusion to their origin story.
