Seven Great Demon Lords

The Seven Great Demon Lords (七大魔王) are a group of Demon Lord Digimon who each represent one of the Seven Deadly Sins. This group is also known as the "Mao" in Digimon World Data Squad, which simply means "Demon Lords" in Japanese, though pronounced as one syllable instead of two. They are based on various demons from within Judeo-Christian mythology, a reference to Peter Binsfeld's classification of demons, most notably Paradise Lost by John Milton and Clavicula Solomonis Regis, an anonymous 17th-century grimoire. There are also three "Super Demon Lords" who are closely related to the group. These Digimon are based on the Beasts of Revelation, and digivolve from the Seven Great Demon Lords. The data of Digimon consigned to oblivion by the Seven Great Demon Lords is not reincarnated, but is sent to the center of the Dark Area, and becomes the flesh and blood of the Demon Lords.

Members
Some of the species that are members of the Seven Great Demon Lords have also appeared as enemy Digimon in earlier seasons, but were not members of the Seven Great Demon Lords.

Crests
Each of the Seven Great Demon Lords possesses a unique "Crest" (紋章) displayed in one of the seven colors of the visible spectrum. Each depicts one of the seals of the "Seven Olympian Spirits", a group of mythological entities who, under God, ruled over the 196 provinces of Heaven and presided over the natural world for 490 years each. Each Olympian Spirit is associated with a heavenly body, also depicted on the Crest.

Within the space between the two concentric circles is text stating a designated Level (this is "666" for all the crests, a reference to the "Number of the Beast" mentioned in the Book of Revelation), System (the demon that traditionally represents the Demon Lord's respective sin), and Code (the Demon Lord's respective sin). At the bottom of the inner circle is text which specifies a caution for a Purgatory Level ranging between 1 and 7, corresponding to the arrangement of Purgatory within Dante Alighieri's La Divina Commedia.

The structure of the text is in the following format:


 * LEVEL:___ SYSTEM:___ CODE:___ (repeated twice)
 * CAUTION! PURGATORY LEVEL ___

The seven Crests also appear together as the "Crown of the Seven Deadly Sins", worn by both Lucemon Shadowlord Mode and Ogudomon, and appear as seals upon the "Gate of Deadly Sins". In Digimon World Data Squad, the individual Crests appear upon "Code Keys", mystical cards which can be used to transform a child suffering from a deadly sin into the respective Demon Lord.

Gate of Deadly Sins
The Gate of Deadly Sins (大罪の門) is engraved with the seals of the seven deadly sins. It is currently unknown what its purpose is.

Digimon Data Squad
Long ago, the Demon Lords almost brought ruin to the Digital World.

Belphemon
Before the events of the series, Akihiro Kurata discovered a temple, inside he found a door bearing the crest of courage, upon entering he found a chest containing a Digi-Egg that would later hatch and digivolve into Belphemon Sleep Mode. Kurata then began a campaign to revive Belphemon by collecting "Digimon life energy", and thereby conquer both the human world and the Digital World—a task he succeeds at by destroying and collecting the life energy of the massive ElDradimon.

Believing he has successfully brought Thomas H. Norstein to his cause, Kurata uses the "Digimon control device" Thomas had made for him to command Belphemon. However, during Belphemon's attack, Thomas double-crosses Kurata, and destroys the control device, forcing Kurata to make another gambit. He seemingly transforms himself into data and merges with Belphemon, taking control over the Digimon's body and transforming it into Belphemon Rage Mode.

Soon after, Thomas comes to join the fight, with Marcus Damon on his way as well. MirageGaogamon faces off against Belphemon only to be stomped on. He might have been finished if Rosemon hadn't seized Belphemon's arm. Belphemon Rage Mode blocks the attacks shot by Rosemon and defeats Crowmon, who reverts back to Falcomon. Through Keenan Crier's rage, Falcomon double warp digivolves to Ravemon and attacks Belphemon but is unable to do anything more than anger him. Belphemon launches an attack at Marcus and Thomas, which Ravemon blocks. Soon, Kurata loses control of Belphemon, whose only goal is destruction. Marcus's Digi-Egg hatches and digivolves from Koromon to Agumon.

Once Agumon digivolves into ShineGreymon, Kurata's face emerges from Belphemon's chest and starts to drain electricity from the city to cause Belphemon Rage Mode to grow and swallow a number of space oscillation devices to give it the power to tear rifts between both worlds, threatening to bring both worlds crashing together. He defeats RookChessmon and BishopChessmon, who revert back to the two PawnChessmon. ShineGreymon digivolves into Burst Mode and destroys Belphemon Rage Mode, with help from Marcus' D.N.A. going straight through Belphemon Rage Mode's chest, where Kurata's face is.

Despite the fact that, normally, Belphemon's Sleep Mode is not considered a member, the voice over for Belphemon Sleep Mode includes it as one.

Digimon World Data Squad
The "Mao Digimon" are created when one of the Code Keys of the Seven Deadly Sins is merged with a person who exhibited the respective sin.

During a series of Digimon attacks, earthquakes, and disappearances, the Mao Digimon reveal themselves with an attack from Creepymon. Five of them, Belphemon, Barbamon, Lilithmon, Beelzemon, and Leviamon, are quickly defeated, releasing their respective Code Keys and the children they were each made from; Lilithmon is revealed to be created from Yuma Kagura, the little sister of one of DATS's researchers, Tsukasa Kagura. Meanwhile, a private investigator named Kosaburo Katsura and his Digimon attempt to steal the Code Keys.

After Leviamon is defeated, Tsukasa appears and reveals that he is behind both Kosaburo and the Mao Digimon; he wants to release Lucemon in order to become the strongest Tamer, and had his henchmen DemiDevimon kidnap the children and transform them into the Mao Digimon, while Creepymon would take the Code Keys of the defeated Mao Digimon to apply to Lucemon's seal.

After a defeat in the Doomsday Forest, Creepymon attack DATS Headquarters and is defeated again. Manami Nitta, a young girl, runs up to the dying Creepymon, and he releases his human, who is revealed to be Manami's father and a lost DATS member named Masaki Nitta. Kagura had told Creepymon that the only way to return home to the Real World was to retrieve the Code Keys and release the seal on Lucemon. He reveals that Kagura already has the Code Key of Wrath. As Thomas realizes that Creepymon's attack was merely a distraction to give Kagura time to release the seal, Masaki begins to dissipate; he had spent too much time as Creepymon, and was no longer anything more than data.

Kagura finally releases Lucemon, who fights DATS but is defeated. Kagura then reveals that he himself is the Code Key of Pride, and is absorbed into Lucemon; while the first six Code Keys would free Lucemon from his seal in the Dark Area, the Code Key of Pride allows him to leave the Dark Area entirely. Although Lucemon is defeated once again, he transforms into the terrifying "Cho-Mao". Despite this form's overwhelming power, DATS manages to defeat him as well, freeing an ashamed and repentant Kagura and ending the Mao Digimon crisis.

Lucemon
As the Demon Lord (超魔王), leader of all the other Mao Digimon, it takes all six of the Key Cards to unlock him from his seal. Tsukasa Kagura wishes to use his power to become the strongest Tamer; Lucemon Chaos Mode has other plans, however, and refuses to be used. After being defeated, Lucemon Chaos Mode digivolves to the Demon Lord form, the final boss, only to be defeated once more.

Barbamon is the Demon Lord who has taken over the Host Computer Yggdrasill in the System World, where he now makes his base. He aims to take over the Digital World by obtaining all the DigiMemories for the future of Digimon, NEO, already having the Dark DigiMemory. For that purpose, he creates the Commandments and recruits Shou Kahara and Peckmon, who have the Bird DigiMemory.

As a member of the Seven Great Demon Lords, he forces himself into System World and confronts Yggdrasill on the policies of "Art" Digimon, Digimon born with Tamers. Upon deciding that revolution is in order, Barbamon merges with Yggdrasill and became the host computer itself. He fights Tsurugi Tatsuno but is killed when VictoryGreymon destroys him. His last act is to give his gathered DigiMemories to NEO, giving him consciousness.

Barbamon appears one last time when the other DigiMemory holders restrain NEO; his Dark DigiMemory imprinted with his consciousness gives NEO the ability to attack Tsurugi and Yuu Inui, only to have his own Commandments turn on him.
