The Demigod Files

The Stolen Chariot

Angry that their sister Clarisse La Rue was allowed to ride in Ares' chariot because they usually use the chariot, Phobos and Deimos decide to steal it from her. They then hide it in the Staten Island Zoo, and use it as bait to catch their sister and Percy Jackson.

Deimos fights Percy but is defeated and disappeared. Deimos changed his appearance to match Ares in order to scare Clarisse, but he disappeared again after she overcame her fear. 

The Heroes of Olympus

The Blood of Olympus

While underground in Phobos's and Deimos's temple, Piper McLean and Annabeth Chase fight the giant Mimas. Piper sacrifices her cornucopia to her brothers. After Mimas's defeat, the face of Deimos on the wall falls onto the giant, killing him. As only a god and demigod together can kill a giant, presumably Deimos caused this to happen to kill Mimas. Then Piper thanks her brothers, and requests a way out of the cave. Phobos opens up a tunnel for them to get back to the surface along his twin.

Personality

Deimos is known to be more aggressive than his brother, Phobos.

Despite his cold behavior towards Clarisse, Deimos isn't all that bad, as he accepted his other half-sister Piper's request for help.

Appearance

Deimos is described as a muscular teenage boy with a brutal face covered with scars. He is dressed in jeans, a black shirt, and a leather jacket.

Deimos has the standard powers of a god.

    • Persona Worst Fear Generation: Phobos has the ability to make individuals see their worst fears  through eye contact. In The Demigod FilesClarisse saw her father in a fury and Percy saw all his friends from Camp Half-Blood in flames. However, Phobos can only do this to one person at a time.
      • Terror Generation: Deimos has the ability to bring terror to a large crowd. In The Demigod Files, he brings a large sea monster that scares many mortals.
  • Teleportation: Deimos can vanish to other locations.

  • Swordsmanship: Deimos is a sword fighter. Despite of being a son of a war god, he is a terrible physical combatant likely because he never had to rely on his skill and thus never trained.
