The ruler of the Greek Titans is Cronus, often seen as a precursor to the Olympian gods. As the leader of the Titans, Cronus symbolizes time and harvest, wielding a sickle. His narrative includes the overthrow of his father, Uranus, and the subsequent fear of being dethroned by his own children. This vicious cycle culminates in his son, Zeus, leading a rebellion against him, resulting in the rise of the Olympian gods and the establishment of a new order in Greek mythology.
