Kronos was the powerful King of the Titans. He was deeply honored by all of the other Titans, including his brother Hyperion. (XWP: "The Titans") He also had power over time. (HTLJ: "The End of the Beginning")
Kronos gained more power by killing his own father Uranus (HTLJ: "Reunions"). He did so by removing one of his ribs and piercing the heavens. (XWP: "God Fearing Child") One of Kronos's acts as King of the Titans was to create the Abyss of Tartarus. (HTLJ: "Full Circle") Kronos's rule was later considered a Golden Age. A temple honoring Kronos, the Temple of Kronos, was built during this age. (XWP: "The Titans")
When his son Zeus tried to usurp his power, Kronos called forth all the Titans into a war council, in which he appointed Atlas as his field general. (XWP: "The Titans") In order to destroy Kronos once and for all, Zeus found the rib of Kronos. (XWP: "God Fearing Child") With it, Zeus was able to kill Kronos and became the King of the Gods. (HTLJ: "Reunions")
