In "The Fantastic Four: First Steps," audiences will witness Mr. Fantastic, Invisible Woman, Human Torch, and The Thing unleash their abilities to protect Earth from Galactus. But could Franklin Richards, Sue Storm's unborn child, also make an appearance?
During an Empire Magazine interview, Vanessa Kirby (who portrays Sue Storm) sparked fan speculation with a cryptic remark: "Superpowers aren't exclusive to adults."
Since Kirby's Sue Storm is pregnant in the film, Franklin Richards' eventual debut in the MCU is inevitable – a major development Marvel fans have anticipated. As IGN previously noted in April:
Comic readers recognize the significance: Marvel Studios is introducing arguably the most powerful mutant ever – potentially alongside his brilliant sister. Sue's pregnancy could reshape the MCU multiverse.
Franklin possesses reality-warping abilities rivaling cosmic entities like Galactus. With telepathy, dimension creation, and astral projection among his powers, he becomes Earth's ultimate protector.
Future timelines reveal adult Franklin as an immortal guardian of the Marvel Universe, suggesting his powers grow exponentially with age.
Given these extraordinary abilities, might Franklin be pivotal against Galactus? Kirby's hint implies we'll see his powers manifest.

The Fantastic Four will join other MCU heroes in next year's "Avengers: Doomsday," potentially positioning Franklin against Doctor Doom.
Recent updates revealed "The Fantastic Four: First Steps" as the longest MCU film since "Guardians of the Galaxy Vol. 3," while leaked promotional material unveiled Ralph Ineson's Galactus design and Funko Pop! figures teased new characters.
