Earlier today, we reported the rumor that not only has Captain Marvel been cast, but she’ll be making her first appearance in the already superhero-heavy Avengers: Age of Ultron. Having major superheroes make cameos or debut in other films from their respective studios has become the norm, so it’s hardly surprising to hear that X-Men: Apocalypse — which is said to primarily focus on the First Class cast — will feature a few cameos from other X-Men…including one pretty exciting mutant in particular.
