Seven Great Demon Lords

The Seven Great Demon Lords, or "Nanadaimaou" in Japanese, are seven incredibly powerful evil Digimon. As a group, they are not spoken of in either the Digimon television series or any of the Digimon manga, although many of the members have appeared in both. If they have a collective goal, it is unknown. Some of The Seven Great Demon Lords are said to be Fallen Angel Digimon - to be specific, Daemon is said to be a fallen Seraphimon and Lilithmon a fallen Ophanimon. Each time a member of The Seven Great Demon Lords appeared in the anime or manga, they were a major or final boss. Each of the Seven Great Demon Lords also represents one of the Seven Deadly Sins, which represent the vile aspects of human nature, which is a counterpoint to the seven crests of the DigiDestined that represent pure aspects.

Members
The names are derived from names demons or other figures from Christian and Jewish mythology: Satan, Beelzebub, Lucifer, Lilith, Barbatos, Leviathan, and Belphegor meaning that the main members are:


 * Lucemon Falldown Mode　(ルーチェモン フォールダウン モード): Pride
 * Leviamon　(リヴァイアモン): Envy
 * Daemon　(デーモン): Wrath
 * Belphemon　(ベルフェモン): Sloth
 * Barbamon　(バルバモン): Greed
 * Beelzemon (Belzebumon ベルゼブモン): Gluttony
 * Lilithmon　(リリスモン): Lust

Lucemon Falldown Mode is presumed to be the leader of the group. Lucemon Shadow Lord Mode (also known as Lucemon Satan Mode in the original and "the dragon") seems to have some connection with the Seven Great Demon Lords, as their crests appear on his back during the Divine Atonement attack.

Crests
These digimon are all connected to the dark crests, which happen to be the seven deadly sins: wrath, gluttony, pride, lust, greed, envy, and sloth. They are the opposite of the crests of the first seven DigiDestined which are courage, friendship, knowledge, love, sincerity (purity), reliability (faith), hope, and light. Presumably, each crest correlates with another one but there is no information on whether a crest of darkness exists, to counter the crest of light. However a card called the Digimental of Darkness (Yami no Dejimentaru) exists.

Minor Figures
These Digimon are not members of the group, but share the type "Demon Lord."


 * Ghoulmon (Deathmon デスモン)
 * MaloMyotismon (BelialVamdemon ベリアルヴァンデモン)
 * Murmuxmon　(ムルムクスモン)

Digimon Adventure 02
A Daemon appeared in this series with the target to get into possession of the Dark Seed inside Ken Ichijouji. He fought against the Digimon of the DigiDestined and although they combinded their attacks they weren't able to destroy him. However they finally got rid of him by sending him to the Dark Ocean.

Digimon Tamers
The character Impmon from this series made a contract with Zhuqiaomon to become stronger and thus the powerful Digimon let Impmon digivolve to Beelzemon. In this form he was quite villainous and even killed Leomon, the partner of Jeri Katou. He however recognised his wrongdoing and became a good character.

Digimon Frontier
In this series the Demon Lord Lucemon Chaos Mode appeared, the digivolved form of Lucemon. In this form he easily defeated the DigiDestined but was then destroyed by Susanoomon. He then digivolved to Lucemon Shadow Lord Mode.
