A good chunk of Doomsday could focus on a clash between Avengers and X-Men with RDJ’s Doom cackling in the background, with a kidnapped Franklin by his side. The premise certainly gives the Fantastic Four a reason to breach their multiversal walls and zip over to 616 to meet the New Avengers.

In Marvel Comics, Franklin Richards is an immensely powerful mutant who can alter reality itself. This comes from the cosmic ray-mutated genes he inherited from his parents. "The Fantastic Four: First Steps" depicts Franklin in the same way; his powerful potential is the driving force of the movie.

As MCU fans wait for Avengers: Doomsday, The Fantastic Four: First Steps has a reveal that should tide them over for a while.
