For those of you who are unaware, Ares is a major player within Wonder Woman’s corner of the DC universe.
Based upon what we have seen from this latest trailer, it looks like Ares has pulled the strings behind the scenes to escalate The Great War, and his new chemical weapon is a trump card to further entrench humanity in its bloodiest conflict.
He is the Greek God of War, and he derives his power and strength from the conflict of men.
The more we battle one another, the stronger he gets.
