The Dark Masters (in Japanese: ダークマスターズ, Dāku Masutāzu) are a group of 4 evil Mega level digimon that seeks to rule the Digital World forever and the main antagonists of the second half of the Digimon anime. Each Dark Master is a powerful Mega Digimon, who rules some part of their main lair Spiral Mountain. Like most villains in Digimon (with the exception of Myotismon), the Dark Masters never last long against the Digidestined. They are MetalSeadramon, Puppetmon, Machinedramon, and Piedmon. They were resurrected in Digimon Adventure Tri Movie 4: Loss.
