Phobos (Ancient Greek: Φόβος - "fear") and Deimos (Ancient Greek: Δεῖμος - "dread") are the gods of fear and terror in Greek mythology. They were twins, sons of Ares and Aphrodite. The two of them would often accompany their father as he rode into battle on his chariot, alongside Enyo, goddess of war and bloodshed, and Eris, goddess of strife.
