Hide this area Mythology

Ares, the greek ged of war, is one of the sons of Zeus and Hera. In early roman history, Mars was a god of spring and growth and only over time became the equivalent of the greek god Ares.

The god Ares always rushed into the thick of battle, not caring who won or lost as long as blood was shed.
