5 Things That Definitely Won't Be In X-Men: Apocalypse
5. Celestial Influence
Although En Sabah Nur was an impressive mutant in his own right, he didn't truly become Apocalypse until he came across the fabled technology of the Celestials, and it would be remiss to deny their heavy influence on his powers and abilities. In the comics, they are an entire race of high-concept aliens who conduct grand experiments across the galaxy.
In last year's Guardians of the Galaxy, the Collector (played by Benicio del Toro) shows footage to the Guardians of a Celestial annihilating a planet using the film's MacGuffin, the Power Stone. Additionally, Knowhere itself (the mining city that functions as the Collector's base of operations) is the severed head of a single one of these imposing beings.
Unfortunately, due to rights ownership by different studios, the X-Men franchise is quarantined from the greater Marvel universe, preventing Singer from using Celestials as a major source of Apocalypse's power.
It's not too large of an issue - the film can wave away the villain's immense power by vaguely referencing "advanced technology," or even citing them as his own innate gifts. The latter certainly gels with Apocalypse's “survival of the fittest" creed.
