Ahriman

Ahriman, also known as Angra Mainyu by others, is the twin brother and rival of Ohrmazd (Ahura Mazda), serving as the God of Evil in the divine pantheon. In his bid to overturn the rule of his brother, Ahriman manipulated and corrupted various beings into serving him to wage war against the Ahuras. In the end, however, he was defeated and imprisoned by Ohrmazd along with most of his surviving lieutenants.

Personality
Not very bright. Chaotic and a liar. Not very clever. While he did suceed often, he would never let them be all and keep pushing the limit, never releasing his own limits which results in his losses. A troll and a bit of an jerk for no real reason. He embodies all the evil of a person's heart.

The forced imprisonment by the Ahura, along with the punishment of witnessing the evolution of Humans, has caused Ahriman's general personality to changed drastically to the point of being two different beings. His mind has calmed where he can make more rational decisions without giving into his impulses, thinking and sympathizing with others and understanding their emotions, and no longer flies into a rage whenever his plans do not go as he wanted. While not what one would consider book smart, his observations of humanity has given him practical intelligence regarding how people interact with one another and how to formulate long term plans and strategies.

Powers & Abilities
Equal in power to his Ahura Mazda.
