The Hekatonkherires (Greek: Ἑκατόγχειρες - "Hundred-Handed Ones") are one of the three races of beings born to Ouranus and Gaia. They are giants of storms and hurricanes. They got their name because they have a hundred arms, fifty on each side of their bodies. Despised by their father, the Hekatonkheires were thrown into Tartarus alongside their brothers the Elder Cyclopes, guarded by the monster Kampê. Many years later Zeus, with his brothers and sisters, freed the Hekatonkheires and the the Elder Cyclopes from their prison to help them in their war against the Titans. The Hekatonkheires threw rocks at Mount Othrys, reducing the mountain to half its original size. After the Titanomachy, the Titans were cast into Tartarus, and the Hekatonkheires were made their jailers.
