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 darkness, which is a counterpoint to the seven crests of the DigiDestined that represent purity.

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:


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

Lucemon Chaos Mode is presumed to be the leader of the group. Lucemon Shadow Lord Mode (also known as Lucemon Satan Mode 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.

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)

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 DigiDestined which are courage, friendship, knowledge, love, sincerity, reliability, hope, kindness, miracles 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.
