Ares is the Greek god of war. He is one of the Twelve Olympians, and the son of Zeus and Hera. In Greek literature, he often represents the physical or violent and untamed aspect of war, in contrast to his sister the armored Athena, whose functions as a goddess of intelligence include military strategy and generalship.

Deimos, "Terror" or "Dread", and Phobos, "Fear" or "Horror", are his companions in war. According to Hesiod, they were also his children, borne by Aphrodite. Eris, the goddess of discord, or Enyo, the goddess of war, bloodshed, and violence, was considered the sister[citation needed] and companion of the violent Ares. In at least one tradition, Enyalius, rather than another name for Ares, was his son by Enyo.

Ares may also be accompanied by Kydoimos, the demon of the din of battle; the Makhai ("Battles"); the "Hysminai" ("Acts of manslaughter"); Polemos, a minor spirit of war, or only an epithet of Ares, since it has no specific dominion; and Polemos's daughter, Alala, the goddess or personification of the Greek war-cry, whose name Ares uses as his own war-cry. Ares's sister Hebe ("Youth") also draws baths for him.
