Who is the god of war?

The story behind the answer

Ares is the Greek god of war, specifically the brutal, chaotic side of combat—bloodshed, fury, and clashing armies. By contrast, Athena governs strategic warfare and wisdom. The other options fit different domains: Zeus rules the sky and kingship, Hades the underworld, and Apollo prophecy, music, and the sun. As the son of Zeus and Hera, Ares often appears as a fierce, impulsive warrior.

For memory: Ares’s Roman counterpart is Mars, whose moons are Phobos and Deimos—named after Ares’s sons (Fear and Terror) who ride with him into battle. Think “Ares = ARmed, AggRessive” to recall his association with raw combat, helmets, spears, and the dogs and vultures of the battlefield.
