The Dark Masters are a group of four powerful Mega-level Digimon created by Apocalymon who have banded together to conquer the Digital World. Each member of the tyrannical group presides over a different section of the world, as well as lead individual armies.
|MetalSeadramon rules the Net Ocean and presides over the "Deep Savers", an aquatic army. He is very arrogant and short-tempered, easily losing his temper when his enemies get the best of him. MetalSeadramon prefers to destroy his foes rather than have make sport them, and unlike the other Dark Masters who enjoy executing their minions for its own sake, MetalSeadramon only executes his henchman when they fail him.|
|Puppetmon rules the forests from a secluded mansion and presides over the "Wind Guardians". He is the smallest Dark Master and has the personality of a spoiled, psychopathic child. He loves to play with his victims, enjoying their confusion and delighting in their deaths, even if they are his own minions. Despite this, he is very gullible and prone to temper tantrums.|
|Machinedramon rules the cities and presides over the "Metal Empire", an urban army. His WaruMonzaemon has enslaved a colony of Numemon in the city's bowels. Machinedramon is quiet, but is just as ruthless and sadistic as the other Dark Masters. He is able to match Izzy's wits, and is willing to employ scorched-earth strategies to eliminate his enemies.|
|Piedmon rules the wastelands and presides over the "Nightmare Soldiers", a demonic army. Piedmon is easily the most powerful of the Dark Masters, as well as the most cruel; he also has a sadistic sense of humor, often cracking jokes. He is a master of deception and trickery, and acts as the leader of the Dark Masters.|
