Apocalymon(sometimes known as Apokarimon) is a Mega, Virus type Digimon. The only organic part of its gigantic body is the humanoid figure on its top. Apocalymon holds the grudges of all the Digimon who were prevented from evolving. He is able to learn and utilize any technique a Digimon would learn by simply watching them. Apocalymon was sealed away in the Dark Zone because of its vicious nature and destructive tendencies.
 Anime Appearances
Separated from the rest of the Digital World and forced to watch moments unfold, Apocalymon grew to despise the Digimon who were allowed to exist and intended to destroy the entire Digital World. As a result, Apocalymon began to influence events such as the reign of the Dark Masters and other evil Digimon that the Digidestined defeated. Upon Piedmon's defeat, with the Digital World completely gone, Apocalymon reveals himself and he even self mutilated to show both his warped ideals and resolve. From there, using the attacks of many of DigiDestined's previous enemies, Apocalymon dedigivolves the Digimon and destroys the Crests before deleting the DigiDestined and their partners. However, still possessing the Power of the Crests, the Digidestined return to existence with their Digimon as they manage to defeat Apocalymon, destroying all his claws and the humanoid part of him. However, Apocalymon uses his last resort attack Total Annihilation to destroy himself and everyone else. Luckily, the Digidestineds' refusal to give up enables their Digivices to create a barrier to contend the blast with only Apocalymon destroyed.
 Digimon Tamers: Battle of Adventurers
Facing Omnimon, Apocalymon is defeated as he reformatted into Mephistomon while entering the real world. Omnimon knew Mephistomon wanted to destroy the world, because this was what Apocalymon wanted to do before he was destroyed and reformatted.

Apocalymon is one of the Digimon the Player must face at the Infinity Tower. At first, he knows no mercy and is determined into reducing everything to smithereens, but as the player defeats him, he enters in a catatonic state, forever wondering if "love" and "mercy" can be applied to his existence.
Apocalymon is a random enemy encounter in the MAGAMI sea base.
Apocalymon is the first of the Boss Digimon the player is bound to defeat. He uses generic fire and ice techniques to attack, and most of his body is electrified, so the player is unable to get to its main body. The player can shut down the electricity by destroying mace-shaped structures. When his main defense system is shut down, Apocalymon shows that his main body is not bound to the mechanized sphere body, but can detach himself at will.
