Deimos // (Ancient Greek: Δεῖμος, pronounced [dêːmos], meaning “dread”) is the god of terror in Greek mythology. He was a son of Ares and Aphrodite, and the twin brother of Phobos; Deimos served to represent the feelings of dread that befell those in the midst of battle, while Phobos personified feelings of fear and panic. Like Phobos, Deimos served as one of Ares’ attendants, and the two of them would often accompany their father as he rode into battle in his chariot, alongside Enyo, goddess of war and bloodshed, and Eris, goddess of strife. Deimos, the smaller of Mars’ two moons, is named after this mythological figure. The god’s Roman equivalent was Formido or Metus.
Deimos was the son of Ares and Aphrodite. He is the twin brother of Phobos and nephew of the goddess Enyo who accompanied her brother Ares into battle, as well as his father's attendants, Trembling, Fear, Dread and Panic. Deimos is more of a personification and an abstraction of the sheer terror that is brought by war and he never appeared as an actual character in any story in Greek Mythology. His Roman equivalent was Formido or Metus.
In popular culture
He appears in the fantasy novel Devil May Cry by Sherrilyn Kenyon.
He also appears in God of War: Ghost of Sparta, although here he is the brother of Kratos. An oracle had foretold that the demise of Olympus would come not by the revenge of the Titans, but by a marked warrior. Ares interrupts the childhood training of Kratos and Deimos, Athena at his side, and kidnapped Deimos due to his strange birthmarks. After Kratos becomes the God of War, he learns from his mother that his brother isn't dead, but trapped and tortured by Thanatos, God of Death. Kratos goes out to rescue his brother but when he frees him, Deimos is enraged that he was taken in Kratos' place and they end up fighting. Thanatos intervenes and takes Deimos to Suicide Bluffs, where Kratos saves Deimos from falling to his death. Kratos and Deimos set out to fight Thanatos, Thanatos kills Deimos and is then destroyed by Kratos.
Deimos is referenced in the name for a class of powerful corvettes in the 3D space shooter Freespace 2, as the Deimos-class.
Deimos appears in the animated Wonder Woman film. Here, he is sent by Ares to kill Wonder Woman, but is defeated by her in battle. Held by Wonder Woman's lasso which forces men to tell the truth, and asked where Ares is, he commits suicide rather than reveal his master's location.
Deimos appears in season five of Hercules: The Legendary Journeys and in the final episode of season 5 of Xena: Warrior Princess. He is killed by Xena after she is given the power to kill Gods by the Archangel Michael.

In the most recent printing, they first appear in volume 1 and are addressed by name after they attack Sailor Moon. Mars mentions that Phobos and Deimos hardly ever attack humans. Later when Sailor Mars transforms for the first time, she calls on them to join her in battle. They appear with her throughout the manga series.
