Seven Great Demon Lords

The Seven Great Demon Lords (七大魔王), also known as the "7 Demon Lords", "Seven Deadly Digimon", or "Mao Digimon", are a group of Demon Lord Digimon who each represent one of the. They are primarily based on the "Princes of Hell" in 's "", also called the "Seven s" in modern occultism. Digimon replaces two of Binsfeld's princes with other demons popular in Judeo-Christian mythology, and several characteristics of the members are drawn from John Milton's ' and the anonymous grimoires ' and . There are also two "Super Demon Lords" who are closely related to the group.

The Seven Great Demon Lords are the chief nobility of the Dark Area and each member has the right to command legions of the "Nightmare Soldiers", if they so wish. They are also able to subvert the cycle of reincarnation presided over by Anubismon—instead of having the chance to be reborn, the data of their victims becomes their own flesh and blood. Despite their might, certain other demonic Digimon, such as GranDracmon, are powerful enough to stand outside their authority. Some other Demon Lords such as MaloMyotismon are rumored to be part of this group, but are not members. The group has a natural rivalry with the Royal Knights.

Crests
Each of the Seven Great Demon Lords is associated with a corresponding "Crest" (紋章), and this association becomes more prominent when they undergo X-Evolution, as their new forms incorporate their crest in some way into their design.

Each crest is displayed in one of the seven colors of the, and depicts a of one of the "", 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 "" 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 .

In Digimon World: Next Order, the Seven Deadly Digimon each create a tower out of boredom after having agreed not to fight each other, but the towers are soon destroyed by the Malevolent Fist.

Digimon Data Squad
Long ago, the Demon Lords almost brought ruin to the Digital World. However, they were stopped and reverted to Digi-Egg form, then sealed away to be forgotten.

Belphemon
Some time before Marcus's induction into DATS, Akihiro Kurata discovered a temple which hid the sealed Digi-Egg of the Demon Lord of Sloth, Belphemon. He retrieved the egg and it eventually hatched into Belphemon Sleep Mode, after which Kurata began a campaign to awaken the Demon Lord by collecting "Digimon life energy", which would allow him to conquer both the human and digital worlds. Using his army of Gizumon to permanently murder many different Digimon, Kurata eventually collects the required energy after slaying 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 reassert control by transforming himself into data and merging with Belphemon, which causes it to transform into its Rage Mode.

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

Once Agumon digivolves into, Kurata's face emerges from Belphemon's chest. He then drains 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 and, who revert back to the two. ShineGreymon digivolves into 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.

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. However, they can be destroyed with enough hard work before they can fully regain their strength.

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, Kagura appears and reveals that he is behind both Kosaburo and the Mao Digimon, as he wants to release in order to become the strongest Tamer. He 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 but is defeated again. A young girl named Manami Nitta runs to the dying Creepymon, who reverts to his human form and is revealed to be her father, 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. Masaki reveals that Kagura already has the Code Key of Wrath, but as Thomas realizes that Creepymon's attack was merely a distraction to give Kagura time to release the seal, Masaki begins to dissipate, as he had spent too much time as Creepymon and was no longer anything more than mere data.

Kagura finally releases Lucemon, who fights DATS but is defeated. However, its defeat proves to be only temporary, as Lucemon quickly revives himself and transforms Kagura into the Code Key of Pride, then absorbs him. While the first six Code Keys removed the seal on Lucemon, and the Digisoul charge awakened him, 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. However, the cards still exist and the data of the Mao digimon has not yet been deleted.

After each Mao Digimon is defeated, a new incarnation of its trait appears at the location of its demise. The DATS team tracks each new incarnation down, and the Mao bestow their power onto the member of the team that best exemplifies their trait, generally after a fight. This allows the team member's Digimon to take the Mao Digimon's form through Digivolution. Agumon gains Belphemon's and Creepymon's, Lalamon gains Lucemon's, Gaomon gains Barbamon's, Falcomon obtains Leviamon's power, Biyomon gains Beelzemon's, and Renamon gains Lilithmon's.

Lucemon
As the Cho-Mao (超魔王), leader of all the other Mao Digimon, it takes all six of the other Code Keys to release Lucemon from his seal in the Ice Caverns. He used his dark powers to manipulate Tsukasa Kagura's bitterness towards Thomas to have him begin a quest to retrieve the Code Keys from his fellow Mao Digimon's data to free him from imprisonment, all the while making him think he was in charge of the evil Digimon working for him. Upon being unsealed and given a DigiSoul Charge from Kagura, Lucemon proceeded to fight the DATS team, but lost. Seeing that he needed to gain more power from the Dark Area, Lucemon betrays Kagura by turning him into the Code Key of Pride and absorbing him to gain freedom from the Digital World. Confronting the DATS team again, Lucemon digivolves to the Demon Lord form, the final boss, only to be defeated once more.

However, Kagura keeps his end of the bargain and by using five of the Code Keys, breaks down the barrier between the two worlds enough for it and other dangerous Digimon to leave. In the real world, it tries making contact with former DATS member Misaki Nitta's daughter, who sees that he is within the evil Digimon. However, a final battle between Creepymon and the DATS team frees Nitta from him, but at a heavy cost.

Lucemon is later found even further into the Frost Cathedral and states that yet again, he had been watching everything the Hero had done and was only reaffirmed that the Hero is a force of good and that they arrive to their conclusions through battle. Lucemon then decides that the winners of battles are good, and the losers are evil and then digivolves into the embodying of evil itself, Lucemon Satan Mode, and fights the Hero because Lucemon wants to shed the tag of being evil, so clearly winning against the Hero will mean Lucemon is now good, whilst losing means it will just add another sin to his history.

Beelzemon intercedes when it comes across a and Otamamon being threatened by  and, incensed at the craven display. He easily fends off their attack, but the pair return to their boss,, who sends his lieutenant to assist them in expanding his territory. The trio post wanted posters of Beelzemon to turn sentiment against him, accusing Beelzemon of a wild, bloody rampage, and successfully but ineffectually convince a crowd of Guardromon to attack him. However, Beelzemon learns of the deception when it reunites with Falcomon and Otamamon, and after being ambushed by Goblimon, Raremon, and the Guardromon a second time, he forces Goblimon to admit that it was SkullSatamon, and therefore ultimately Creepymon, behind his troubles. SkullSatamon emerges and attempts to use the now disillusioned Guardromon as human shields, infuriating Beelzemon, who soundly trounces SkullSatamon. Beelzemon spares his life so that he can deliver a message to Creepymon—to deal with Beelzemon directly if he's going to give him problems.

Some time later, Beelzemon easily defeats. With a bruised ego, Mephistomon sets a trap for Beelzemon by casting In-Training Digimon into a portal.

It had also unintentionally found the last of Beelzemon's power whilst doing so and though initially relunctant to give it its power back, not wanting to help a member of the Seven Deadly Digimon, it changes its mind after hearing that Impmon had promised to help its new friends who had trusted it but also because defeating Gulfmon was important. It gives Impmon back its power – allowing it to turn back into Beelzemon, with the two then joining the battlefield just as Gulfmon had defeated Rasenmon. The combined might of Rasenmon, a member of the Seven Deadly Digimon, and a member of the Royal Knights isn't enough to defeat Gulfmon however which forces Beelzemon and Gallantmon to digivolve to Beelzemon: Blast Mode and. The three of them are then able to kill Gulfmon. After the fight, Gallantmon reminds Beelzemon that they are actually enemies though they agree to fight later and not now as they used up too much energy in fighting Gulfmon. Beelzemon then leaves on Behemoth.

It continues searching for the exact location the Vademon told it and is able to find it, though is once again ambushed by the two Royal Knights. Wanting to use Millenniummon's power to destroy the Digital World so it could remake it in its own image, it travels back in time though ends up taking the two Knights with it. Now back to when the Vademon had summoned Millenniummon more than a decade before, it plans to ambush it and then seal off its will and mind so that it would do its bidding and also planned to force it to digivolve to its "final World destroying form", then would return with it to the future and destroy the World. The Royal Knights state they will not allow that to happen, though when Millenniummon arrives the gate suddenly gets interfered with, with having been convinced by Rasielmon to help as well. It then travelled back in time as well to stop Lucemon's plan and was able to interfere with the ritual, causing Millenniummon to instead appear as an illusion. The three of them then continue to fight Lucemon and eventually are joined by the ghosts of and, with  and  having convinced them to stop Lucemon from destroying the World. The Legendary Warriors see that it is not powerful enough on its own whilst in its Rookie form to destroy the World which is why it needed Millenniummon's power and since Goblimon and Raremon had asked them to stop Lucemon, not kill it, they decide to instead seal away Millenniummon and are able to do so with the help of Mastemon and Rasielmon. Angered, Lucemon defeats the Angels and the Legendary Warriors (with the Legendary Warriors's power running out, causing them to disappear) though this outburst of anger is enough of a distraction for Crusadermon and Dynasmon to attack and kill Lucemon.

The trio post wanted posters of Beelzemon to turn sentiment against him, but Beelzemon sees through the plan and forces Goblimon to admit that it was SkullSatamon, and therefore ultimately Creepymon, behind his troubles. After soundly trouncing SkullSatamon, Beelzemon spares his life so that he can deliver a message to Creepymon—to deal with Beelzemon directly if he's going to give him problems. Suitably cowed, Creepymon decides to stop bothering Beelzemon for now, but resentfully plots future vengeance.
