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 has now hit cinemas in the UK, the US, and several other countries, and while the film introduces viewers to familiar faces like Reed Richards and Sue Storm, it's their son, Franklin, who's quietly stealing the spotlight.
