Zeus was the Greek gods' monarch, ruling over Mount Olympus. He was the sky and thunder deity. His main dominion was thought to be on Earth, although there were reports of him slaying giants with his lightning bolt weapon. Zeus took no direct action against the monsters that threatened Earth, but instead sent them meteorites or volcanic eruptions in order to distract humans from what was happening inside his own realm. When Zeus didn't have anything else to do, he would sometimes fight among the gods for supremacy, which usually ended with him winning due to his power level compared to those around him. After deciding that human activity was causing too much damage to Earth, he made the ultimate sacrifice by taking human form so that he could feel pain and fear like everyone else. He then convinced other gods to do the same, at which point all of their enemies on Earth would have been defeated! Zeus ruled over Greece, where his many adventures with women and warfare with his rivals (mainly Apollo and Poseidon) are remembered through history. He also played an important role in determining who would become the first rulers of Rome after its founding by Greeks emigrating from Athens.
