Apocalymon is an Unidentified Digimon whose name is derived from the Apocalypse. He was the final villain faced by the DigiDestined in the original Digimon series. He was originally created from the data of Digimon who were deleted while trying to digivolve, as a Digital World version of the process of Natural Selection. As such, he feels great bitterness toward both humans and Digimon alike, and has the power to revert Digimon to their Rookie levels.
