MCU’s Galactus revealed in Fantastic Four: First Steps final trailer

Fantastic Four: First Steps has released its last trailer, and the two-minute clip makes one thing clear: Galactus is on his way.

The video shows the towering cosmic villain floating above Earth, while the new heroes scramble to prepare. Fans have waited years to see Galactus in the MCU, and Fantastic Four: First Steps finally delivers a first look at him in all his planet-eating glory.

In the fresh trailer, Ralph Ineson’s Galactus looms behind swirling purple clouds as silver energy blasts across the sky. At his side rides Julia Garner’s Shalla-Bal, a new version of the Silver Surfer.

The trailer also offers a glimpse of H.E.R.B.I.E., the team’s chatty robot (voiced by Matthew Wood), and a quick shot of Reed and Sue’s baby, Franklin Richards, clutching a tiny blue blanket.

Directed by Matt Shakman, Fantastic Four: First Steps stars Pedro Pascal as Reed Richards/Mister Fantastic, Vanessa Kirby as Sue Storm/Invisible Woman, Ebon Moss-Bachrach as Ben Grimm/The Thing, and Joseph Quinn as Johnny Storm/Human Torch. The supporting cast includes John Malkovich, Paul Walter Hauser and Natasha Lyonne.

Set in a colourful, retro-futuristic 1960s world, Fantastic Four: First Steps launches Phase 6 of the MCU.

The plot follows Marvel’s First Family as they face Galactus, “their most daunting challenge yet,” according to the official synopsis. The trailer hints at an early clash on the Moon, followed by desperate city-wide evacuations as Galactus closes in.
