Apocalymon

Apocalymon is the main and final villain in Digimon Adventure. He was created by deceased Digimon during a reconfiguration and he was able to breach through the fire wall.

Appearance
Apocalymon is a Mega Level Digimon that resembles very much often an unidentified mutant Digimon on a dodecahedron with pyramidal platforms and large claws connected to DNA strand-like arms. With those arms he can easily reverse the digivolution of a digimon while holding onto it.

Profile
A Digimon who was formed from the deep grudges of Digimon who died out when unable to digivolve before they died, his coming foretold in the prophetic book from ancient times. Although Apocalymon was sealed somewhere, he was released from his prison by Millenniummon.

Digimon Adventure
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 Crest power, 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.
