Zeus' origins and early history mostly conform to the way they are presented in classical mythology. He is a child of the Titans Cronus and Rhea and leader of the twelve Olympian Gods. During a war between the Titans and Olympians, Zeus slays his father and assumes his place as King of the Gods, ruling from Mount Olympus with his sister-wife Hera. He is the father of numerous gods and heroes, the most famous being Hercules.
