As the rest of the Fantastic Four mourn her, Reed puts their son on her chest to say goodbye, and then he miraculously resuscitates her. The parents spend most of the movie worried that Franklin might be some kind of monster like Galactus,

Franklin Richards' reality-warping vs Galactus's Power Cosmic: Here is who we think is the strongest in the MCU after The Fantastic Four.

Worries that he might not be "normal" are confirmed in Fantastic Four: First Steps when Galactus recognises that the boy can wield an unlimited energy known as the Power Cosmic (presumably because of the "cosmically compromised DNA" shared by both of his parents).

In a 1982 arc by John Byrne, Franklin gets frustrated trying to solve a Rubik’s Cube and uses his powers to age himself into an adult body, though he couldn’t actually gain more emotional maturity. He winds up going back to being a kid, placing restrictions on his own abilities to allow him to have something of a normal childhood.

Galactus ends up giving the Fantastic Four an ultimatum, telling a pregnant Sue that he'll spare Earth if she gives up her powerful unborn child to him. The group declines his deal, which further angers Galactus, sending him on a vengeful mission to both destroy Earth and take Sue’s child.

First Steps" has a thrilling ending that teases Dr. Doom and where the MCU goes from here in "Avengers: Doomsday."
