Athena (God of War)

Athena is a character from the God Of War game series, who secretly plays a villain role in the game God Of War III.

Role as a villain
While most of the God Of War games, Athena was the least selfish and most noble goddess, however, in God Of War III, she is affected by Greed, one of the evils of the world which was locked in Pandora's Box. She motivates Kratos in his quest for vengeance against Zeus. She didn't show any of that evil personality in God Of War II, while she was alive, what probably means that she was just pretending to be on Zeus' side. She also claims to have a message for humanity.

In God Of War III's ending, it can be assumed that what she actually wanted was to take the great power of Hope back, rebuild the world and rule over the mankind alone as the sole all-powerfull god.
