Gia was born from Chaos, and with him gave birth to Uranus. With Uranus, she gave birth to the Cyclops, and Hekatonties, which he imprisoned in Tartarus due to their monstrous appearance. Angered by this, after the Titans were born, Gia encouraged them to overthrow their father, which the youngest, Cronus did.
When Cronus, leader of the Titans, was informed that one of his children would overthrow him, he become so fearful he decided to imprison them all in his belly, devouring his young children Hades, Poseidon, Hera, Hestia and Demeter, one by one. No longer being able to see another children die, the mother Rhea, hid the youngest Zeus from his father. When he grew up, Zeus become determined to free his brothers from Cronus and started a disproportionate retribution against the Titans for the sins of Cronus. After the six children of Cronus and Rhea had overthrown the Titans, the three brothers among them cast lots for three domains: Poseidon drew the sea, Hades the netherworld of the dead, and Zeus the sky. But the Earth and high Olympus were left common to all.

When a God wave spilled forth from the creation of the Fourth World, the Earth was seeded with great power. It first manifested in the form of old gods, then of metahumans. Some of the oldest of these gods were hidden from the universe until the time of ancient Greece by the sorceress, Hecate. Hecate reasoned that the Olympian Gods (as they would eventually be called) were greatly weakened after usurping power from their father Cronus and the Titans of Myth. She feared that other powerful gods in the universe (notably Darkseid of Apokolips) would seize Earth for himself. Because of Hecate's enchantment, Darkseid wrongly believed that he and the other New Gods pre-dated the Olympians.
In Marvel the Greek and Roman pantheons are merged.
It is said that Gaea, the elder Earth Goddess, created the Olympian race, but their exact history is a bit cloudy. They could have been born on Earth, or another dimension. It is said that Gaea mated with Uranus and subsequently gave birth to the first generation of the Olympian race which. These beings were called the Titans. The youngest son of Uranus was fated to one day overthrow his father and take his place as ruler of his race. This son, Cronus, the whom had grown to become the most powerful titan, wounded and slew Uranus and took control. However, right before dying, Uranus prophesied that Cronus would also die by the hand of one of his own children. Desperate to hold onto his power and position, Cronus worried each time his wife, Rhea, bore him a child so he imprisoned each of them, six in all, in Tartarus, the lowest, harshest level of Hades, as they were born. Angry at him for doing this to their children, his wife Rhea hid her sixth child upon his birth so he might be spared this terrible fate. This child was Zeus. Living in ancient Greece, Zeus grew up with humans in Crete and became quite powerful. After years of training to master his power, Zeus sought out others whom had been wronged by Cronus, including the Cyclopes and Hekatonchieres and even one Titan, Prometheus, all of whom he formed alliances with. Zeus marshalled his forces and then confronted Cronus. War ensued with Zeus and his allies emerging as the victors. During and after this war Zeus found and freed his other siblings Neptune, Pluto, Hera, Demeter and Vesta. The defeat of the Titans and the rise of the Gods, under the rule of Zeus, ushered in a golden age for mortal man.
The rise of the Gods lead to many duties being assigned and roles being filled. Zeus became the Olympian God of Thunder and ruler, also called "Sky-father", of the Olympian gods. Hera became his wife and the Olympian Queen. Zeus' brother Neptune became the God of the Sea and his other brother, Pluto, assumed the role of the God of the Dead. Others, born later, grew up to assume their own mantles. Ares is the son of Zeus and Hera and is the Olympian God of War. Athena, daughter of Zeus, is he Olympian Goddess of Wisdom. Zeus's twin children, Apollo and Artemis, are the God of Light & Music and the Goddess of the Chase, respectively. Hephaestus, son of Zeus and Hera, is the Olympian God of Fire. He serves as the blacksmith and weapons maker of the gods. Aphrodite is the Olympian Goddess of Love and her son Eros is the Olympian God of Love. Hermes, son of Zeus and swiftest of the gods, is the god of commerce and medicine and serves as Zeus's messenger. Dionysus is the Olympian God of Wine. The champion and strongest of the Olympian Gods is the former demigod Hercules, son of Zeus and Olympian God of Strength, who earned full-godhood through his heroic feats in defense of mankind and even the Olympian Gods, themselves. There are many, many other Olympian Gods and Goddesses of minor importance whom populate the Olympian realm. These includes the former sea nymph Venus, who is a member of the Agents of Atlas and Asterius, a minotaur whom served in the Howling Commandos, Cephalus the Huntsman of Zeus, as well as several others.
Powers and Abilities
The typical attributes of Olympian Gods include superhuman levels of all the usual abilities and senses humans have. These include, but are not limited to strength, speed, durability, sight and hearing. They are also immune to all human diseases and maladies. Though all Olympians have super-human levels of physical abilities, a great number of them have been born with either higher levels than those of even their fellow gods in some of these areas or any of a multitude of all-together different, non-physical, powers which include matter manipulation, weather control, amphibious abilities, power over magic, etc.
The Olympian Gods do not age or die and as such they are true immortals. The source of the Olympian Gods' immortality is their practice of eating ambrosia and drinking nectar made by Hebe, Olympian Goddess of Youth, from the apples of immortality.
