"The Apocalypse" is a term that refers to any one of a great number of potential "end time" events that would either destroy the Earth, end all life on the planet, kill or subjugate all humans, bring Hell to Earth, or other similar results.
- Every Apocalypse tends to have its own "Four Horsemen." These are usually representative embodiments of the forces behind them, not actual anthropomorphic personifications of those forces. (The Horseman of Death is generally not Death, etc.)
- Many different religions and other traditions have their own vision of the Apocalypse, ranging from the prophesied return of Lucifer to the final war of the gods or the opening of the Outer Gates.
