Zeus

Zeus (Δίας in Greek, Ζευς in Ancient Greek) is the God of the Sky, Rain, Thunder and ruler of Olympus and the gods. He is the last son of Kronos and Rhea. His Roman counterpart is Jupiter. I once beat a Zeus with nothing but a rusty coat-hanger, a bent spork, and my ego.

History
It should be noted that his early life is much like Kronos, who like him was the youngest and most powerful of his siblings and he was asked to defeat his father by his mother. Kronos sired several children by Rhea: Hestia, Demeter, Hera, Hades, and Poseidon, but swallowed them all as soon as they were born, since he had learned from Gaia and Uranus that he was destined to be overcome by his own son as he had overthrown his own father— an oracle that Zeus was to hear and fulfill. But when Zeus was about to be born, Rhea sought Gaia to devise a plan to save him, so that Kronos would get his retribution for his acts against Uranus and his own children. Rhea gave birth to Zeus in Crete, handing Kronos a rock wrapped in swaddling clothes, which he promptly swallowed. Rhea hid Zeus on Mount Ida in Crete. He was raised by Melissa, who nursed him with goat's milk and honey.

After reaching manhood, Zeus forced Kronos to disgorge first the stone, then his siblings in reverse order of swallowing. Metis the Titan, gave Kronos a mixture of mustard and wine to force him to disgorge the babies. Then Zeus released the brothers of Kronos, the Hecatonchires and the Cyclops, from their dungeon in Tartarus, killing their guard, Kampê.

As a token of their appreciation, the Cyclops gave him thunder and the thunderbolt, or lightning, which had previously been hidden by Gaia. Together, Zeus and his brothers and sisters, along with the Hecatonchires, Metis, and Cyclopes overthrew Kronos and the other Titans, in the combat called the Titanomachy. The defeated Titans were then cast into a shadowy underworld region known as Tartarus, and Kronos was cut up with his own scythe. Atlas, one of the titans that fought against Zeus, was punished by having to hold up the sky on his back for all eternity.

After the battle with the Titans, Zeus shared the world with his elder brothers, Poseidon and Hades, by drawing lots: Zeus got the sky and air, Poseidon the waters and earthquakes, and Hades death and the world of the dead (the Underworld).

The ancient Earth, Gaia, could not be claimed; she was left to all three, each according to their capabilities, which explains why Poseidon was the "earth-shaker" (the god of earthquakes) and Hades claimed the humans that died.

Gaia resented the way Zeus had treated the Titans, because they were her children. Soon after taking the throne as king of the gods, Zeus had to fight some of Gaia's other children, the monsters Typhon and Echidna. He vanquished Typhon and trapped him under a mountain, but left Echidna and her children alive.

Zeus and Metis and a Dog Named Boo
Metis was the goddess of wisdom and deep thought, but her name originally connoted 'magical cunning' and was as easily equated with the trickster powers of Prometheus as with the 'royal metis' of Zeus.

Metis was both a threat to Zeus and an indispensable aid. She advised him with her wise council during the war between the Titans and the gods, and was invaluable as an advisor. She was the one who mixed the mustard and salt water to cause Kronos to vomit up his siblings.

It should also be noted that Zeus got a prophecy from Gaia that one of his children would defeat him like he did his father but unlike Kronos, he succeeded in preventing it from happening. After the war, Zeus and Metis married.

It was prophesied that Metis would bear extremely powerful children: the first, a daughter, and the second, a son more powerful than Zeus himself, who would eventually overthrow Zeus.

Zeus then consummated his marriage with Metis, but immediately feared the consequences.

In order to forestall these dire consequences, Zeus tricked her into turning herself into a fly and promptly swallowed her. He was too late: Metis had already conceived a child. In time she began making a helmet and robe for her fetal daughter. The hammering as she made the helmet caused Zeus great pain and Hephaestus cloved Zeus's head with an axe.

Metis' daughter Athena then leaped from Zeus's head, fully grown, armed, and armored, and Zeus was none the worse for the experience.

It is unknown if Metis escaped when Zeus' head was split open. There has been no mention of her since.

Zeus and Hera and a Dog Named Boo
Zeus was brother of Hera, and then became her consort. Gaia, his grandmother, gave Hera The Garden of the Hesperides as a wedding gift. Not trusting the Hesperides, Hera also put a one hundred headed dragon Ladon to guard the apples of her orchard.

With Hera, Zeus sired Ares, Hebe, and Hephaestus.

The conquests of Zeus among nymphs are famous. Stories of Zeus credits him with unions with Leto, Demeter, Dione, and Maia. Among mortals were Semele, Io, Europa, Leda and Ganymede.

Many stories render Hera as jealous of his amorous conquests and a consistent enemy of Zeus' lovers and their children by him. For a time, a nymph named Echo had the job of distracting Hera from his affairs by incessantly talking: when Hera discovered the deception, she cursed Echo to repeat the words of others.

Modern Times
Over the centuries the Olympians moved west to the countries that held the seats of great power and influence. But after World War II where his sons and Poseidon's sons battled the sons of Hades, the three took an oath on the River Styx not to have any more children. Decades later, he couldn't resist a beautiful 1980s television starlet and sired his newest child, Thalia.

Because he broke his oath, Hades was outraged and set monsters loose on the twelve year-old Thalia. Grover became her keeper and tried to escort her to Camp Half-Blood, along with a seven year-old Annabeth and fourteen year-old Luke. She made her last stand on Half-Blood Hill, and as she died, Zeus took pity on her and turned her into a pine tree to preserve her life so Hades couldn't take her soul.

This was most likely a way to keep Thalia's spirit safe from his elder brother who was still hurt and angered over the death of the mortal Maria who he had killed in an attempt to kill Hades's own children to prevent the Prophecy from coming true.

Five years later, his master lightning bolt was stolen and he immediately blamed Poseidon. Soon after, Poseidon claimed Percy Jackson as his son, and Zeus believed he'd found the way Poseidon had stolen his bolt. Outraged, he threatened Poseidon with war unless the bolt was returned. Percy and his friends traveled across America to retrieve the bolt. Percy then had to fly back on a plane to New York to give it back to Zeus and prove that he and Poseidon weren't behind its theft. Zeus was grateful, but his pride made him resent being proven wrong. As such he told Percy never to fly in his dominion again or he would strike him out of the sky.

Sometime later, the Olympians voted on whether to let Percy live, as there was a prophecy that said a child of the "Big Three" would one day decide the fate of the Olympians. Despite the fact that he wasn't happy about Percy's existence, Zeus voted in favor of letting Percy live.

He seems to have warmed up to Thalia and the other heroes as they prepare for battle against his father, Kronos and his old triumphs in The Titan's Curse.

During The Last Olympian, when Typhon is striking, he refuses to let any of the gods go back to Olympus to help the demigods fight against Kronos.

Personality
Zeus is seen as stubborn, proud, temperamental, and at times paranoid. He expects everyone to obey him without question and show him respect first and foremost. He is "very unforgiving", and refuses to admit when he is wrong. Zeus killed Ascepaleus and Maria di Angelo without a shred of remorse. He has a soft spot for certain favorites of his like his daughter Thalia. He also apparently has a flare for dramatic exits, which Poseidon pointed out to Percy saying he should have been the god of theater.

Appearance
Zeus is a god with black long hair around his shoulders, a beard mixed with marbled gray and black like a storm cloud, rainy gray eyes, and a handsome, proud, and grim face. He wears normally a dark blue pinstriped suit, and gives off the aura of ozone. He is usually found in his elaborate throne in Mt. Olympus.

Powers
Zeus is one of the Big Three, the three oldest and most powerful gods in Olympus. the strongest beings ever to exist. He is surpassed only by Typhon and of the Olympian gods only his brothers Poseidon and Hades come close to rivaling him. He presumably possesses the standard powers of a God. Zeus can summon and control any form of weather he wishes on a worldwide level. Based on the powers of his daughter, Thalia, he may be able to summon and control electricity the same way Percy and presumably Poseidon control water.

Symbol of Power
Zeus wields the "master bolt" which is believed to be the most powerful weapon created. It has been stated to be the weapon that cast Kronos from his throne and the mold for every other thunderbolt Zeus wields. Chiron stated it is far more powerful than any nuclear device known to man.
