Enyo is the goddess of war, destruction, carnage and bloodlust. She is the twin sister of Ares, her constant companion in battle.  Her Roman counterpart is Bellona.


Early life

Enyo was born to Zeus and Hera. Her twin brother was Ares.

Enyo became responsible for orchestrating the destruction of cities. She would often accompanies Ares in battle.

Trojan War

During the fall of Troy, Enyo inflicted bloodshed and terror in the war with Eris and her nephews, Phobos and DeimosAchilles later depicted the aforementioned gods in his shield.

Tale of Dionysus

Enyo was involved in the war of her half-brother Dionysus and his followers against the Amazons, a battle which Dionyusus easily won in India. 

Battle against Typhon

Unlike most gods, who were very frightened and left, Enyo was so delighted by the war that she refused to choose sides in the battle between Zeus and Typhon.

The Heroes of Olympus

The Blood of Olympus

Enyo is mentioned by Reyna Ramírez-Arellano, who compares her to her mother Bellona.


As a child of two Olympians (one of them is a member of the Big Three), Enyo is a very powerful goddess. She is considered a minor goddess.

  • Strategy Skill: As the Goddess of War, Enyo is naturally extremely skilled strategy, tactics and statistics of war. She frequently orchestrates the destruction of cities. Despite this, she fights without a strategy in mind, very much like her brother.
  • Odikinesis: As the Goddess of War and Bloodlust, Enyo has absolute control over the feelings and emotions of war, such as hate and rage. She frequently induces these feelings to orchestrate the destruction of cities.
  • Prowess in Battle: As the Goddess of War and Destruction, Enyo is a fierce warrior. She is a master of both armed and hand-to-hand combat.
  • Telumkinesis: As the Goddess of War, Enyo has absolute control and divine authority over weapons. She knows everything about a weapon when she sees it.
  • Necromancy (possibly): As the Goddess of Carnage, spirits on the losing side of every war might own a tribute to Enyo.



  • At Thebes and Orchomenos, the festival Homolôïa was celebrated in honour of Zeus, Demeter, Athena and Enyo. The festival was said to have received the name from Homoloïs, a priestess of Enyo.
  • Enyo isn't a major Olympian because the Olympians didn't need another war god: Athena and Ares are worshipped more as a deities of war.
