They appear as the skeletal remains of once female soldiers, covered partially in armor and adorned with a plumed helm. They have two methods of attack, either to stand back and attack Kratos from a distance with explosive projectiles, or to strike at him up close with the sword they carry. At any time a grab can be initiated by the circle button and Kratos will seize an Olympus Fiend, and throw it to damage other Fiends. After enough damage has been dealt, an instant kill can be activated to finish the Olympus Fiend off, Kratos will tackle it to the ground and impale it in the head with its own sword.
Kratos can summon the Fiend with the Claws of Hades. When summoned, they ignite themselves thus burning surrounding enemies.
- Olympus Fiends are almost identical to the Hades Fiends in God of War II, in terms of how they attack and how Kratos damages and kills them.
- If paired with a Cyclops Berserker in the battle arena, they will climb up and control the cyclops like Beast Lord.
