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.
Typhon
The Typhonomachy—Zeus' battle with, and defeat of Typhon—is just one part of a larger "Succession Myth" given in Hesiod's "Theogony". The Hesiodic succession myth describes how Uranus, the original ruler of the cosmos, hid his offspring away inside Gaia, but was overthrown by his Titan son Cronus, who castrated Uranus, and how in turn, Cronus, who swallowed his children as they were born, was himself overthrown by his son Zeus, whose mother had given Cronus a stone wrapped in swaddling clothes to swallow, in place of Zeus. However Zeus is then confronted with one final adversary, Typhon, which he quickly defeats. Now clearly the supreme power in the cosmos, Zeus is elected king of gods. Zeus then establishes and secures his realm through the apportionment of various functions and responsibilities to the other gods, and by means of marriage. Finally, by swallowing his first wife Metis, who was destined to produce a son stronger than himself, Zeus is able to put an end to the cycle of succession.
