First Steps introduces the world to Mister Fantastic, Invisible Woman, Human Torch and The Thing, but there's one other character of importance.

In Marvel Comics, Doom’s fixation on Franklin is legendary. He views the boy’s near-limitless powers as the key to creating and ruling Battleworld, a twisted reality of his own making as seen in Secret Wars.

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.

Franklin’s powers allowed him to create the universe, dimensions, avoid mind control, and every other cool power you can think of. Franklin Richards is considered a Beyond Omega Level mutant, and he is the only one in that category, making him the most powerful mutant on Earth.

Franklin Richards isn't just another superhero offspring; he's one of the most powerful characters ever created in the Marvel Universe.

Marvel Studios is taking taking the MCU in a wild direction with The Fantastic Four: First Steps , and the biggest reveal yet is the introduction of Franklin Richards, one of the most powerful characters in Marvel Comics history.
