The Apocalypse Twins, Uriel and Eimin, are a duo of supervillain twins from Marvel Comics. In the storyline the Twins were kidnapped by Kang the Conqueror and taken to the future where he raised them. The Apocalypse Twins later travelled back in time, attacking and killing a Celestial. Using the powers gained from the dead Celestial they raised four dead superheroes from death (Banshee, Daken, Grim Reaper, and Sentry), having them serve as their "Horsemen of Death" as they fought against the Avengers. In the end much of the storyline with the Apocalypse Twins was undone through time travel, leaving the fate of Uriel and Eimin up in the air.
