Eligos Gremory

Eligos Gremory (エリゴス グレモリー, Erigosu Guremorī) is a nascent Dark Mage created by the mad scientist Azazel. Referred to as Genma (原魔, Origin Demon), Eligos is an amalgamation of multiple entities. A powerful Dark Mage, Eligos was created by Azazel through four of the Thirteen Calamities, extremely powerful demons that were sealed during the climax of the Dragon Civil War, and using the DNA of Amon to stabilize the genetic coalescence.

Eligos was created from such powerful entities as a potential candidate for Azazel's Ultimate Demon (究極魔, Kyūkyoku Ma lit. Final Devil), his strongest creation. To Azazel, Eligos' process of creation was his attempt to play 'God', and she's considered his second attempt at such a feat, after Thanatos.
