Ares
Hypocritical.
Ares could describe the mortal world as many things, but hypocritical was the best description that came to his ancient mind.
Heroes from his world, from space, and other domains liked to say that humanity had good qualities about them. But like everything that lived, it was a corrupt race. Secretly, they craved violence and conflict. It fed them like some perverse stimulant.
So he capitalized on that, kickstarting global conquests and instigating wars between neighboring countries. He wasn't really a villain; he was just showing humans for what they were.
Monsters.
And would Wonder Woman save them then?
A/N: Making war a living, breathing character is always cool. Want to know what comes next? The dark side of Shazam!
