- Complete Monster: Angra Mainyu, known by his Persian name of Ahriman, is the Evil Twin of creator god Ahura Mazda, and the antithesis of everything good and just. Declaring that "it is not that I cannot make anything good, but that I will not," Angra Mainyu sought to prevent Ahura Mazda from creating life in the first place, by slaying the primal bull, his first creation. He seduced the daevas (demons) away from Ahura Mazda, transforming them into spiteful beings living only to spread fear and hatred. When Ahura Mazda created sixteen lands, Angra Mainyu responded with sixteen scourges, including old age, disease, war, vice, and death. He created the monster Ai Dahāka, destined to slay one-third of the Earth's population, and turned him loose in the world. He made two separate attempts at destroying the Earth's water supply and leaving all creation to die of dehydration. He made Jeh, the primal whore, so that women would suffer from menstruation, birth pangs, and mistrust from men. He tried to coerce Zoroaster into coming over to his side, and then set the daevas upon him when he would not. Responsible for the very existence of evil, Angra Mainyu works to seduce men and women away from Ahura Mazda, so they might join his campaign for control of reality. Hating everything good and just, and angry that he is not the one who created everything, Angra Mainyu's ultimate goal is the annihilation of the universe.
