Diablo III: Six Requested Demons

The editors at GamePro have compiled a list of six demons from various mythologies that they'd like to face in Blizzard's Diablo III. Their top pick:
#1: ANGRA MAINYU and SPENTA MAINYU

Known For: Being the embodiment of evil and good, destruction, and constant bickering.

Angra and Spenta Mainyu are actually two beings, complete opposites, the demon of ultimate evil, and the angel of ultimate benevolence. In Zoastrian lore, Angra is pit against Spenta at opposite ends of the moral spectrum. It is Angra Mainyu that inspired the evil thinking that created the demons that torment the world, deceive mankind and do all manner of vicious acts. Spenta Mainyu, on the other hand is the god of life, the personification of every good act and feeling in this universe.

Would make a great Diablo 3 boss because: Not only do you have to fight the embodiment of evil, but you must also deal with the embodiment of good. This means that during the showdown with them, one boss would likely have the ability to heal the other, and in concert they create an unbelievably devastating force. At the end of the day, purging the world of good and evil, the heroes are left to make their own fate, and after all, isn't that what all games are about?
