Apocalymon (Adventure)

Revealed to be responsible for creating the chaos in the Digital World and creating the Dark Masters, Apocalymon debuted as a very strong enemy to the DigiDestined. After demonstrating his used attacks, he used his "Reverse Digivolve" attack to revert all of the Digimon back into their Rookie forms (Gatomon reverted to Champion instead). He also destroyed their tags and crests and sent the DigiDestined to the Data World. However, once there, the DigiDestined realized that they had the crest power within them all along, and their Digimon were once again able to digivolve. They rematerialized into the Digital World and faced off. After the other digimon destroying all of his Death Claws and distracted apocalymon, WarGreymon and MetalGarurumon destroyed his humanoid form. The DigiDestined thought that they had won; however, as he explained, the humanoid form was only a part of him, albeit an important one. He then attempted to take both worlds down with him with Total Annihilation, his ultimate attack. However, the Digivices of the DigiDestined contained the attack so all it achieved was his death.
