However, the MCU is also setting up its own team of X-Men, with Jake Schrier developing an X-Men reboot. Spider-Man: Brand New Day doesn’t even use the word “mutant,” so the film clearly doesn’t set definitive rules as to how mutants work in the MCU. However, Brand New Day sees Jean seemingly have a second mutation; something that is definitely part of X-Men lore. This will undoubtedly be a difficult task, but to do this most effectively, making these types of big changes is probably for the best. Giving other MCU mutants unique origin stories provides fans of the FOX movies a reason to check out these new films, as they aren’t just rehashing stories from two decades ago.
