:The character is not to be confused with the Milestone and DC Comics villain Holocaust (often referred to as Pyre), who was once a member of the Blood Syndicate.
Holocaust is a fictional character that appears in comic books published by Marvel Comics. The character first appeared in X-Men Alpha (February 1995), and was created by Scott Lobdell and Roger Cruz.
Holocaust, originally known as Nemesis, is the purported son of Apocalypse and also served as one of his Four Horsemen in the Age of Apocalypse timeline. His physical form, nearly destroyed by Magneto in revenge for Nemesis' murder of his daughter Scarlet Witch is contained in a crystalline exo-armor of phasing and shape-shifting properties.
Adopting the name Holocaust, the transformed Horseman slaughtered millions in North America in Apocalypse’s name. After a culling in Chicago, Holocaust was confronted by X-Man Sabertooth and the two fought. Holocaust won and took Sabertooth to his Infinite Factory. The X-Men pursued and the overconfident Holocaust was taken by surprise and nearly killed by the young X-Man Blink. With the help of her team, Rogue nearly defeated Holocaust but he teleported himself to Apocalypse’s stronghold just in time.
