Zeus
Zeus played a dominant role, presiding over the Greek Olympian pantheon. He fathered many of the heroes and was featured in many of their local cults. Though the Homeric "cloud collector" was the god of the sky and thunder like his Near-Eastern counterparts, he was also the supreme cultural artifact; in some senses, he was the embodiment of Greek religious beliefs and the archetypal Greek deity.
Because I'm the Goddess
Zeus, the God who created Pandora, is a diminutive crowned child with a big ego and an even bigger mount, which he calls 'Kratos'. When his power was taken from him many years ago, it was broken up and scattered across Japan as 'Gifts'. His first attempt to retrieve them failed, and it took him so much energy to make her that he slept for a century. Upon awakening, he creates Pandora and sends her to Earth to do the job properly. She succeeds in Volume 3, defeating his previous Goddess and confronting him. Pandora plans to kill Zeus but realizes that without the Gifts and the power of chaos, Man has no will to live. She instead kills herself, and Zeus is forced back to Heaven to sleep for another hundred years.
