In Greek mythology, what were Ares' special powers?

In addition to being an immortal god, Ares possessed overwhelming strength and physicality. He was always armored and armed, and rode a huge chariot flanked by the demigods Phobos, Enyo, his sister Eris and Deimos. Ares was the Greek god of war and the son of Zeus and Hera.

Phobos was the demigod of fear, Enyo of horror, Eris of strife and Deimos of terror. Ares was invulnerable to man-made weapons, unless the man attacking was aided by a god. In fact, he often lost altercations with his fellow gods, such as when the goddess Athena defeated him on the battlefields of Troy.
