Brontes was a Cyclops in Greek mythology. He was the son of Ouranos and Gaia and the brother of two other Cyclopes; Arges and Sterope. His other siblings included the Hecatoncheires and Titans. The Cyclopes and Hecatoncheires were imprisoned in Tartaros by their father for their appearance. In a bid to overthrow his father Cronus promised to free his brothers. However, he failed to do so. They were eventually freed by their nephews Zeus, Poseidon and Hades, whom they aided in the Titanomachy. "Brontes" means "thunder".
