Following the acquisition of the X-Men and Fantastic Four from 21st Century Fox, Marvel Studios now has access to mutants. There's a lot of speculation about how the group might be introduced, with some fan theories positing that one of the snaps in Avengers: Infinity War or Avengers: Endgame is responsible. However, writers Christopher Markus and Stephen McFeely don't think that will be the case.
In an interview with The Hollywood Reporter, the writing team debunked the theory radiation from the snap would lead to mutants. The two explained they weren't even aware that the snap had torn a hole in reality until they watched the recent trailer for Spider-Man: Far From Home.
"Anything is possible, but I don't [know] whether you'd need that," Markus said. "Genetic mutation is genetic mutation. It just happens. Maybe they are already out there."
"I do think that whenever [Marvel Studios President] Kevin [Feige] decides to do X-Men or Fantastic Four, it won't be how you think it's going to happen," said McFeely. "I think he's going to have a real clever version of it."
It's clear from their remarks that Markus and McFeely don't know for certain one way or the other, so it's totally possible Marvel Studios might end up linking the introduction of mutants to the snap at some point down the line. However, Feige previously said fans shouldn't expect to see mutants in the MCU for "a very long time."
