Deimos and Phobos were twin brothers, the sons of Ares and Aphrodite.

Aphrodite was the goddess of beauty and love, while Ares embodied the brutality of war. Despite their differences, the two deities had one of the most famous love affairs in Greek mythology.

Their children were often more closely associated with one or another of their parents, but most had one thing in common. Both love and war gave rise to strong, overpowering emotions.

Their twin sons, Deimos and Phobos, were most often associated with their father. They were the personifications of fear.

As twins the two were very alike and almost inseparable. They embodied variations of the same emotion and were almost always seen together, affecting the same side of a battle to lead to a total breakdown of morale and discipline.

Deimos was the god of terror and dread. Phobos was the god of panic and rout.
