Jubilee

Another fan favorite mutant from the comics, Jubilee has made cameos in all three films of the original trilogy (very, very small cameos). Portrayed by Lana Condor in X-Men: Apocalypse, she is a mutant who can create pyrotechnic energy plasmids to various effects, mostly intended to distract the enemies.

Since this is the first time when she will have a full role in the Mutant Cinematic Universe, it isn’t known anything about her.

However, Bryan Singer did say that X-Men: Apocalypse is both an ending and a beginning, which most likely means that her character will be developed in future movies, just like all the other young characters to be featured next year.
