The Fantastic Four: First Steps | First Trailer

Galactus is one of Marvel's most powerful characters, but I'd wager his power levels will be secondary to another in the MCU's upcoming Fantastic Four: First Steps. The MCU will finally debut its version of Marvel's First Family on July 25, 2025, where they will appear alongside the iconic Marvel villain, Galactus, as portrayed by Ralph Ineson. This will be Galactus' second appearance in a live-action movie adaptation, putting pressure on Marvel to improve upon the widely lambasted version depicted 17 years ago in Fantastic Four: Rise of the Silver Surfer.

In that regard, things are looking positive for The Fantastic Four: First Steps. An early look at its main characters revealed Galactus' gargantuan eyes as he peers through a window, establishing that he will, at least, be composed of solid matter. Given Marvel's track record, this is likely to extend to a comic-accurate costume and power set, which will make him one of the most powerful villains ever introduced in the MCU. Nevertheless, early signs suggest that Galactus will not be the most powerful character in the movie.
