Zeus (Saint Seiya)

Originally, Masami Kurumada (Creator of Saint Seiya series) would develop a Zeus chapter, wherein Zeus would be the villain, so, is was a cancelled villain.

But, Kurumada intends in the future, make a Zeus chapter to the series, so, Zeus is a confirmed villain.

Historic
Zeus was the god that dethroned Gaia, Chronos and the titans, and the Olympic Gods, dominated the Earth and the humans, and splited it in four reigns, connected with the humans: Tenkai (where the leaders lives, lead by Zeus), Sekai (the world of humans; maybe, the first reign; lead by Zeus), Kaikai (the water world; lead by Poseidon) and Meikai (the world where the humans goes; only the pures, goes to the Elysium. Meikai and Elysium are lead by Hades). Each Olympic god, lead a thing connected with the humans; Ares, for exemple, lead the war.

But, the three Zeus's sons (Abel, Artemis and Athena) keep the earth. Artemis, control the Moon in the Earth, and Abel, control the Sun; so, they were the gods responsible to keep the day and the night in the Earth; Abel was substituded by Apollo after his rebellion. Zeus leave the Earth with Athena, and Athena, with out a divine body, was born with a human body, so, she always dead in various ages, with humans feelings and pains. That's did Athena love the humans, even with them sin, considering these sins, the normal way of being, always preaching for the pardon of all humans sins. This caused the fury of Poseidon and Hades; possibly, in the future, Zeus and Olympic Gods (according Poseidon) will fight with Athena, to reconquer the Sekai and revenge the death of Hades and Abel and the defeat of Poseidon.
