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.

First Steps mostly focuses on its titular group, but Mister Fantastic, Invisible Woman, Human Torch, and the Thing aren’t the only heroes introduced in the film. One major player doesn’t get a superhero name,

While none of the previous onscreen adaptations of the Fantastic Four included the super-powered baby, director Matt Shakman tells Entertainment Weekly that it was always his plan to debut Franklin into the MCU.
