Nightcrawler

The protagonist of an amazing introductory scene in X2 returns to the Mutant Cinematic Universe. If he was previously portrayed by Alan Cumming, this time around Kodi Smit-McPhee will become the blue teleporter.

It isn’t known what his role will be in X-Men: Apocalypse. However, Bryan Singer did say that Mystique is the one who brings him into the fold, for Professor X to train him and help him accept his appearance. Several questions appear right now, with the most important one concerning Mystique’s reasons.

In the comics, Nightcrawler is her son with Azazel (the red teleporter from First Class). Could this be the reason why Mystique wants to help him? It is in the realm of possibility, especially since it isn’t known what exactly happened with the Hellfire Club immediately after First Class. And since Mystique doesn’t age like normal people do (she is a mutant, after all), we cannot exclude this possibility (though he can still be a long-lost son of Azazel and an unknown character).
