The Hekatonkheires (also known as the Hundred-Handed Ones) are the brothers of the Cyclops and have one hundred hands and fifty faces depicting different emotions. They are classically the children of Gaea and Ouranos and the elder brothers of the Cyclopes. They were the primeval gods of violent storms, Briares particularly of sea storms. Their brothers the Elder Cyclopes were also gods of storms, particularly of lightning.
They are powerful enough to break mountains and they are as tall as the sky. Before the First Olympian War, the Hekatonkheires were imprisoned in Tartarus and were guarded by Kampê. They were tortured by Kampê until Zeus freed them and the Hekatonkheires helped the Olympians win the First Olympian War. Two of them, Cottus and Gyges, later served as guards to Tartarus' entrance. Briares lived at the bottom of the sea.
