Marvel Have Already Shown How X-Men Could Enter The MCU
1. How This Solves Marvel's X-Men Problem
When the MCU kicked off in 2008, it was likely that no one at Marvel envisaged that both the X-Men and Fantastic Four would ever be introduced. It was about doing the best with what they had, and though the Avengers were always a revered outfit in the comics, to general audiences, they couldn't dare match the appeal of the X-Men.
Now, in 2018, that role has completely reversed. But to say that the X-Men are redundant would be disingenuous. Their arrival would only enhance the MCU's already formidable roster, but it's a question of how, not when, that needs addressing first. Mutants are such an essential component of the Marvel Universe that to retroactively insert them would cause a few headaches for all concerned, but in providing an explanation that accounts for their absence and then their presumed resurgence, the Terrigen Mists are the perfect solution.
Coincide the reopening of Xavier's School for Gifted Youngsters with a sudden reemergence of the mutant gene, and you have the perfect way of retaining the older generation of X-Men while introducing enough fresh faces to demarcate the MCU's mutants from Fox's own. Looking to the franchise's golden age during the nineties should, then, be a priority, and while the absence of Captain Marvel from the MCU's history books would seemingly be easier to explain, audiences will be willing to forgive a lot to see the likes of Wolverine, Cyclops and Jean hanging around with the Avengers and Fantastic Four.
