Ahriman (Prince of Persia)

Ahriman is the God of Darkness and Evil which is the main villain of the Prince of Persia (2008) video game. For most of the game he is escaping his prison once the tree of life is destroyed. He is also the brother of Ormazd, God of Light and Good. He seems to be formless in shape as he is apparently made of a substance called Corruption.

History
Long before the start of the game Ahriman and his brother Ormazd kept balance in the universe until Ahriman decided he wanted complete control of creation and decided to attack his brother. He started to collect souls of mortals foolish enough to make deals with him making most his mindless slaves. However he did allow some to keep their free will namely an alchemist, a warrior, concubine, hunter and finally a mourning king which is titled the Corrupted. However eventually Ahriman and his forces was sealed into the tree of life by Ormazd. After this Ormazd was deeply hurt by this betrayal and all the damage they both had caused decided to leave the world never to return while telling the tribe named Ahura to guard Ahriman's prison in hopes to prevent his brothers return. After the Corrupted are slayed by being cleansed of his power they face him. Eventually Elika sacrificed herself to seal him away again by restoring the tree of life, much to Prince's displeasure. As Prince mourns Elika he hears Ahriman say he would resurrect her in return for his own freedom. Once Prince does he fulfills his end of the bargain. The game ends with Elika storming off leaving Prince to find another way to defeat this dark god.

Personality
Ahriman has a uncontrollable lust for power and souls to the point he betrayed his own brother in hopes of taking control of reality itself. He is a intelligent enough creature to know the exact word and opportunity to play on peoples emotions as he does with Elika's father and Prince at the end of the game. Despite being a master manipulator Ahriman does seem to posses a degree of honor since he is shown to give what he promised including resurrecting Elika despite her being the one to have just re-imprisoned him inside the tree of life.

Power
Ahriman is portrayed as an nigh-omnipotent deity who is only rivaled by Ormazd himself due to being another deity or those that his brother has granted power to. He might also be an Omniscient as he seems to know most things despite being sealed so long ago. Once freed he is most likely Omnipresent as his essence seems to be spreading across the sky after his former prison's destroyed.
