First Appearance: Wonder Woman 183 (1969)
Creators: Mike Sekowsky and Dick Giordano
Abilities: Master of terror and manipulation, with all the super strength, speed and endurance one can expect from a god—and a mane of venomous snakes.
Backstory: Deimos*, the god of dread, is based on the Greek mythological figure and is the son of none other than Ares and Aphrodite. He and his brother, Phobos, the god of fear, primarily dwell in the Underworld, where they aide their father in plans of conquest and violence in order to bring destruction upon the mortals of Earth.
Naturally, gods of fear and horror would have a ruthless nature, and often seek their fathers approval, so like their father, they despise the Amazons as well as other Olympian Gods. Deimos, usually seen with his serpentine hair, achieves fear projections through the venom of his enchanted helm of snakes, and has been tasked by Ares to manipulate key political and military leaders in order to bring the planet to the brink of World War Three.
First seen along side his father, brother and (then) aunt, attacking Themyscira, he and his brother Phobos would also later attack Diana on her mission in Man’s World, but the Amazon was able to behead Deimos with her tiara. Years later, along with his also dead family members, Phobos and Eris, he would escape the Tartarus and head to Gotham City, where his spirit took possession of the Joker, but was eventually returned back to the Underworld. He would later reappear with an altered appearance as a twin, attempting to blackmail a grieving Veronica Cale, in order to free his father from a prison on Themyscira…where Circe turned him into dog, because of course she did.
*Not to be confused with Deimos, a powerful necromancer and sworn enemy of Travis Morgan, the Warlord.
