In X-Men: Apocalypse, Apocalypse’s ancient burial site is shown inside a pyramid.
The film begins in ancient Egypt, where En Sabah Nur, later known as Apocalypse, is being transferred during a ritual intended to preserve his consciousness. His followers protect him, but the ceremony is disrupted and the structure collapses around him.
This opening establishes Apocalypse as an ancient mutant who has survived by transferring his consciousness into other bodies. The movie then jumps forward thousands of years, placing his awakening in 1983.
The pyramid imagery connects the character to the film’s Egyptian setting, but the story is a fictional superhero interpretation rather than a historical account of ancient Egypt. Production used visual effects and constructed sets to create the ancient environment.
