Who was Zeus?
Zeus was king of all the gods. Zeus ruled the entire universe - no one was mightier than the mighty Zeus. Zeus was not afraid of anything except possibly his wife, the horrible Hera.
He had many powers, some magical, and some that came with his office. Magically, Zeus was the only god who could throw lightning bolts. He could shape shift, and look like anybody. He could throw his voice and sound like anybody. As an elected official, king of all the gods, he could assign jobs to other gods, and take those jobs away.
