With the recent introduction of Franklin Richards in the MCU in The Fantastic Four: First Steps, even though his origins are slightly altered, there is no doubt that he will play a big role going forward.

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.

First Steps culminates with young Franklin Richards facing Doctor Doom himself. Here's why Doom needs Franklin for Avengers: Doomsday.

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.

After a number of false starts, the Fantastic Four have another feature adaptation in the retro-pastiche Fantastic Four: First Steps. This isn’t the first time Mr. Fantastic and co. have appeared onscreen; They were last seen in Josh Trank’s Fantastic 4 (stylized as Fant4stic) and Tim Story’s Fantastic Four films for Fox.
