Dark Masters

The Dark Masters (ダークマスターズ Dāku Masutāzu) are four evil, Ultimate level Digimon from Digimon Adventure, who are extensions of Apocalymon. In the absence of the Chosen Children, the Dark Masters took over the Digital World and reformatted much of it into Spiral Mountain, making it easier for them to conquer.

They all originate from the Digimon Pendulum x.0 series (although Mugendramon debuted in Digimon World). Their armies in Digimon Adventure are each named after the Pendulum version featuring the respective member of the Dark Masters, with exception of Nature Spirits and Virus Busters.

Metal Seadramon
An arrogant and hot-tempered Digimon in control of the Digital World's seas, he commanded Digimon of the Deep Savers, including many Hangyomon and a particularly scatterbrained Anomalocarimon. He was extremely arrogant about his power, boasting an almost impenetrable defense because of his Chrome Digizoid armor. Unfortunately, he was at a type disadvantage against War Greymon's and was ripped through lengthwise with his.

Pinochimon
A very juvenile puppet Digimon, he commanded Digimon of the Wind Guardians and controlled the forest. He showed a special interest in Takaishi Takeru, the youngest of the Chosen Children, challenging him to various games at his mansion. He is best known for toting around a .44 Magnum gun and killing several of his minions during temper tantrums. He was killed by Ishida Yamato's Metal Garurumon.

Mugendramon
Extremely calculating and uncaring, he ruled over Multitask City and commanded Digimon of the Metal Empire family. He had some of the highest offensive power of the group, being able to obliterate entire city blocks with the cannons on his back. Being a dragon type, he also fell to War Greymon's.

Piemon
The leader of the Dark Masters, he watched from the top of Spiral Mountain as his comrades were destroyed by the Chosen Children. He controlled the Nightmare Soldiers, his second-in-command being a Lady Devimon. He was able to shape shift into various forms and cause elaborate illusions, along with the ability to change his opponents into keychains with his versatile Clown Trick. Being too powerful to kill, Takeru's partner, Holy Angemon, sealed him away within his. His victims were returned from their keychain state by Holy Angemon's.

Piemon was among the Digimon brought back due to the formation of Millenniumon, whom he then served. He fights Akiyama Ryo in Piemon's Palace as the fourth boss of the game. He fights Ryo again in Milleniumon's Lair alongside a Meramon, the fourth fight in the boss rush leading to Millenniumon, but is defeated once again.

Infinity Tower's third Battle Arena, unlocked after beating all the Adventure Chosen Children, is centered around the Dark Masters, with the player having to fight Metal Seadramon, Pinochimon, Lady Devimon and Piemon in a row. Piemon himself uses the Four Heavenly Kings Assault deck which is centered around the Dark Masters. All of them wish to harm the player, with Piemon specifically holding a grudge from his defeat against the Chosen Children and vowing revenge, even after being defeated by the player.

While Mugendramon appears in the game in Infinity Tower's first Battle Arena, he's not considered part of the Dark Masters in the game, with Lady Devimon taking his place instead.

After Aiba Takumi/Aiba Ami collects all of the Dark Masters medals, the Medal Man rewards them with a Shine Guard DX and a Dark Guard DX.

After Amasawa Keisuke collects all of the Dark Masters medals, the Medal Man rewards him with a Shine Guard DX and a Dark Guard DX.

Dark Master is a trait given to Digimon cards, namely those that were part of the group in Digimon Adventure, in the Digimon Card Game, introduced in BT-15 Exceed Apocalypse. Digimon that served them in the anime may have effects that specifically target Digimon cards with this trait.
