Ahriman

Ahriman is the Persian god of evil. He attacked Ahura Mazda with a bull that contained the very strength of the world, but Mithras killed the bull with the help of a raven, a dog, a scorpion, an ant, and a snake. Ahriman, titled Ahriman the Malevolent, is never pleased, so he went on to destroy Ahura Mazda and other gods around the world, including Zeus, Odin, Ra (God), and Quetzalcoatl, among others.
