The first cyclopes were raised by Uranus and Gaia. Uranus was not pleased with the monsters and imprisoned them until Kronos overthrew him. During Kronos' rule, he did not release the cyclopes, so his mother Gaia and his wife Rhea plotted against him.
Later in the ages cyclopes were usually worker and weapon makers for the gods. But there has been reports of wild Cyclopes who are often very agreesive to humans and demigods.
