“He’s not like us,” Sue Storm (Vanessa Kirby) tells her husband Reed (Pedro Pascal) at the end of The Fantastic Four: First Steps. “He’s more.”
Sue is referring to their infant son, Franklin, the latest addition to the superhero team. Franklin’s birth is a huge part of Fantastic Four, as is his potential status as a mutant, and Reed spends a great deal of time worrying that the same cosmic entity that changed them will also affect his son. Those familiar with the Franklin of the comics knew that some kind of mutation was inevitable, but Fantastic Four goes all out with its first tease of his true power.
