One of the "Seven Great Demon Lords", it is a Demon Lord Digimon which has the appearance of a long-bearded old man. Residing within the central part of the Dark Area, the den of demons, it manipulates Fallen Angel Digimon to carry out evil to its limit. It is obsessed with all of the treasure which exists within the Network, so out of avarice, and regardless of the means, it has a cruel personality with a greed that would kill Digimon just for a piece of treasure. It is the foremost and most cunning schemer of the Seven Great Demon Lords, and can easily manipulate the Ultimate Deathmon in addition to Fallen Angel Digimon. Its Special Moves are using its demonic staff "Death Lure" to tempt Digimon into an inescapable living hell, converting them to wickedness, and unleashing all of the Dark Area's evil energies at once as an extremely high-temperature explosion that burns up everything without a trace (Pandæmonium Lost). Furthermore, even Belial Vamdemon's Special Move "Pandæmonium Flame" only releases a small fraction of these energies.

長い髭の老人の姿をした魔王型デジモンで“七大魔王デジモン”の一体である。悪魔の巣窟であるダークエリアの中心部に存在し、堕天使型デジモン達を操って悪の限りを尽くす。ネットワーク内に存在するあらゆる財宝に執着し、物欲のためならば手段を問わず、一欠けらの財宝のためにデジモンを殺す強欲で残忍な性格である。堕天使型デジモンの他に、究極体のデスモンを造作もなく操る七大魔王屈指の狡猾な策略家でもある。必殺技は生きては戻れない地獄へとデジモンを誘い、邪悪化させる魔杖『デスルアー｛死への誘惑／餌の意｝』と、ダークエリアの邪悪のエネルギーを一斉解放し、全てを焼き尽す超高熱爆破『パンデモニウムロスト｛破滅の意｝』。尚、ベリアルヴァンデモンの必殺技『パンデモニウムフレイム』でさえ、このエネルギー量の極一部でしかない。
