Apocalypse, known as En Sabah Nur, is one of the oldest and most powerful mutants in the Marvel Universe. His origin dates back over 5000 years to ancient Egypt, where he was born as a human child with deformities. He was cast out and raised by nomads, learning the ways of survival in a harsh world. Over time, he discovered his mutant abilities and became determined to ensure that only the strongest would survive. Throughout history, Apocalypse has amassed immense power through his ability to absorb others' abilities. He became a pivotal figure in mutant history, often clashing with the X-Men and other superheroes.

As a master manipulator, he created several factions, including the Four Horsemen, to further his goals. His character has evolved throughout various media, appearing in comic books, animated series, and films, leaving an indelible mark as a quintessential villain representing extreme ideologies regarding mutation and evolution.
