The Greek god of war is Ares. He is one of the Twelve Olympian gods, the son of Zeus and Hera, and represents the physical valor, bloodlust, and brutal aspects of war. Unlike his sister Athena, who symbolizes military strategy and wisdom in war, Ares personifies the chaotic and violent side of battle. He was not very popular among the Greeks and was often depicted as a destructive force who enjoys the tumult and horrors of war.
