X-Men: 10 Theories For How They Can Join The Marvel Cinematic Universe

Look, this may sound pretty boring, but why not? While it's no doubt tempting to "over explain" the arrival of mutants in the MCU, if they have just been keeping out of the public eye, there's really no reason they can't start emerging from the shadows! After all, if something big enough happens to force Professor X to assemble a team, that could be what leads to more mutants showing up at last.

Just like fans had never heard of Spider-Man before Tony Stark tracked Peter Parker down with that viral clip of him swinging into action, there's no reason to believe mutants haven't been secretly persecuted and saved lives during the course of the Infinity Saga.

Sure, they didn't show up to help take down Thanos, but how would they know to if they've been too scared to make themselves known due to the unexplained nature of their powers? Don't forget that the world's governments enacted the Sokovia Accords to keep track of superpowered individuals, and if you're a mutant, why would you want to risk putting your name on that list?
