The Horsemen of Apocalypse are a team of four elite followers of En Sabah Nur.
The first known incarnation of the Four Horsemen are seen in Ancient Egypt watching as their master uses his powers to construct the pyramids while a vast crowd of people bow before him, chanting his name.
Somehow, Apocalypse makes Storm, Magneto, Angel and Psylocke his new incarnation of Horsemen.
- In the comic books, Apocalypse has often manipulated different mutants into being his Horsemen. Examples include Angel, Wolverine, Gambit, Psylocke, Banshee and Polaris.
- Each Horseman embodies a different horror that humanity has constantly been faced with: War, Famine, Pestilence and Death.
- Bryan Singer stated the Four Horsemen chosen for X-Men: Apocalypse reflect real-world cults and how they tend to have factions associated with politics, military, sex or youth.
- Magneto and Storm's roles as the Horsemen is similar to their X-Men Evolution counterparts, War and Famine, respectively.
