Apocalymon is a fictional character from the Digimon franchise, and the final and true main antagonist in its first season, Digimon Adventure. He was created by deceased Digimon during a reconfiguration and he was able to breach through the fire wall. At his core, Apocalymon is motivated by jealousy and despair. As a creature formed from Digimon doomed to death by natural evolution, he is confined to an empty world of darkness, only able to watch as the reverse world - the world of light - gets to rejoice in happiness as he suffers. Cursing it, he desires to rule over all the Digimon and the Digital World and twist the world to fit him and his darkness. In the English dub, Apocalymon has a dark sense of humor despite him being "required" to be miserable; after explaining his plan to the DigiDestined, he begins to laugh, but quickly stops himself, commenting that he's "supposed to be depressed". In the Japanese version, however, Apocalymon refers to himself in the plural sense, likely in reference to the Biblical Legion, who claimed to be possessed by a multitude of demons acting as a gestalt. Regardless of how the trait is showed, he's clearly meant to be almost completely insane.
