Cronus, the most powerful of the titans, sat atop Mount Olympus. Zeus became the king of Mount Olympus after overthrowing Cronus (his father) and dwelt there with 11 other gods. However, Zeus was not content to be merely one of them. He was angered by the fact that none of the other gods took him seriously as a ruler, so he decided to prove them all wrong by demonstrating just how powerful he was going to be. Using his knowledge from teaching humans how to build weapons, he created many things for battle including guns, bombs, and tanks. The other gods were afraid of him because they knew that if they offended him, he would destroy them like he did his father. However, despite his power, Zeus still had his weaknesses too. He was not immune to pain, and when Metis (a Titaness who was also one of Zeus' wives) saw what he was going to do, she warned him about killing the humans who taught him everything they knew. But it was too late; already far too many people had died for Zeus's actions. When Cronus heard about this, he went up to Zeus on Mount Olympus and tried to convince him not to kill any more humans, but Zeus wasn't having any of it. He saw himself as more than human and didn't feel like he needed anyone else to survive.
