Apocalymon (Adventure)

Apocalymon is a from the Digimon, and also is the primary antagonist in Digimon Adventure, the first season.

Personality
Apocalymon is ultimately jealous of the light. As the beings which composed him were doomed to death by natural evolution, he has to watch as the reverse world, the world of light, get 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 contrast to the English version, the Japanese version has Apocalymon refer to himself in the plural sense. This mannerism is likely a reference to the demon, who was also composed of many. Thus Apocalymon, as a being assembled from the data of thousands if not millions of Digimon, may truly be a plural entity.

Description
Apocalymon's arrival was foreseen in ancient prophecies: he came from beyond the Wall of Fire and was born from the feelings of jealousy and hatred belonging to Digimon who died during Digivolution. A sadistic and tormented soul, Apocalymon wants to make the Digital and Real Worlds into living underworlds to justify the darkness that composes him. His existence generates chaos in the Digital World and in space-time itself, particularly the creation of the Dark Masters.

After the defeat, the last of the Dark Masters, Spiral Mountain disappears, and the children drop into a strange, empty space. Gennai contacts them, revealing that the true cause of the Digital World's afflictions will soon appear. Apocalymon then shows up, and after demonstrating the techniques of the evil Digimon who compose him, he uses his "Reverse Digivolve" to revert all of the DigiDestined Digimon to their base forms. He then deletes their Tags, Crests, and bodies, sending them all to the Data World.

Once in the Data World, the DigiDestined realize that they have the Crests' power within them all along, and their Digimon are once again able to digivolve. They rematerialize into the Digital World and face off in a battle royale in their highest levels. After, , , , and  destroy all of Apocalymon's claws and distract Apocalymon,  and  destroy his humanoid form. The DigiDestined think that they won; however, as Apocalymon explains, the humanoid form is only a part of him, albeit an important one. He then attempts to take both worlds down with him using his ultimate attack, Total Annihilation. However, the children's Digivices contain the attack, so all that it achieves is his own death. As a result, the Digital World reformats and the time difference between the two worlds equalize.
