Phobos

Phobos was the god of fear in Greek mythology, son of the gods Ares and Aphrodite. He was the brother of Deimos (terror), Harmonia (harmony), Adrestia, Eros (love), Anteros, Himerus, and Pothos. He followed his father into battle, along with his companions, Enyo (the war goddess); Eris (the goddess of discord); and his brother, Deimos. The followers of his cult made bloody sacrifices. Phobos was depicted in the shields of heroes who worshipped him, such as Heracles, with his mouth open showing fearful and daunting teeth, according to Hesiod.
