In some versions of Greek mythology, Zeus ate his wife Metis because it was known that their second child would be more powerful than him. After Metis's demise, their first child Athena was born when Hephaestus cleaved Zeus's head open and the goddess of war emerged, fully grown and armed.
Answer and Explanation: In most myths, Athena is the eldest child of Zeus. Athena's mother, Metis, was a powerful Titaness whom Zeus either seduced or raped, depending on the version of the story.
Together, Zeus and Hera had three children: Ares, Hebe, and Hephaestus.
Hebe was the youngest daughter to Zeus and his wife Hera. Her name came from the Greek word for 'youth', and it was thought she had the power to temporarily restore youth in a chosen few.
Zeus never cared much for his two legitimate sons, Ares and Hephaestus.
Perhaps partly because of the strange circumstances of her birth, Athena is often cited as Zeus's favourite child. He also greatly admired her strength of character and fighting spirit. Some believe Athena was Zeus's first born child, which might, somewhat unfairly, suggest why he chose her as his favourite.
1. Apollo: Zeus' Best-Known Son. Of all the sons Zeus fathered, Apollo is perhaps the best known. Apollo was conceived during an illicit affair between Zeus and Leto (Zeus was married to Hera at the time), along with a twin sister named Artemis.
Generally, Zeus is believed to have had over 100 children, but the number could be even greater considering the number of concubines that he had.
Heracles – Son of Zeus and Alcmene
He possessed superhuman strength and courage. Because he was a reminder of Zeus's unfaithfulness, Hera made it her mission to make his life miserable. At one point, she drove him to madness and he killed his own children. To atone for his sins, he went through his famous “Labors”.
But even that trusted source doesn't have them all. In total, Zeus is believed to have fathered more than 50 children! That's not unheard of in ancient Greek mythology.
Zeus fell in love with Io and seduced her. To try to keep Hera from noticing he covered the world with a thick blanket of clouds. This backfired, arousing Hera's suspicions. She came down from Mount Olympus and begain dispersing the clouds.
Why is Zeus married to his sister? To hide her shame, Hera agreed to marry him. It was a violent marriage at best. Though Zeus had pursued his sister and sought to possess her by marriage, he never gave up his lusty ways.
Hephaestus is the son of Zeus and Hera. Sometimes it is said that Hera alone produced him and that he has no father. He is the only god to be physically ugly. He is also lame.
Zeus was also infamous for his erotic escapades. These resulted in many divine and heroic offspring, including Apollo, Artemis, Hermes, Persephone, Dionysus, Perseus, Heracles, Helen of Troy, Minos, and the Muses.
Castor and Pollux (the Dioscuri) are figures from Greek and Roman mythology considered the twin sons of Zeus or Jupiter. Semi-divine figures, they were credited with the role of saving those in trouble at sea or in grave danger in war and were particularly associated with horses and sports.
Dioscuri, also called (in French) Castor and Polydeuces and (in Latin) Castor and Pollux, (Dioscuri from Greek Dioskouroi, “Sons of Zeus”), in Greek and Roman mythology, twin deities who succoured shipwrecked sailors and received sacrifices for favourable winds.
Hera. The most famous of Zeus' wives, Hera was also the sister of the father of the gods, and the goddess of women, marriage, family, and childbirth.
The other gods came to see what the problem was. Hermes realized what needed to be done and directed Hephaestus to take a wedge and split open Zeus's skull. Out of the skull sprang Athena, full grown and in a full set of armour. Due to her manor of birth she has dominion over all things of the intellect.
THE TITANOMACHY: ZEUS DEFEATS HIS FATHER CRONUS
This epic battle was waged for ten years between Zeus and the Olympians and Cronus and the Titans.
Zeus was spirited away to Mt. Dikte on the island of Crete where he was raised by the primeval goddess Gaia (Earth), or in some versions by the Nymphs. Amongst these was the Nymph Amaltheia (in some versions of the myth she was a goat) who suckled the young god.
Impregnation by Zeus
Nonnus classifies Zeus's affair with Semele as one in a set of twelve, the other eleven women on whom he begot children being Io, Europa, Plouto, Danaë, Aigina, Antiope, Leda, Dia, Alcmene, Laodameia, the mother of Sarpedon, and Olympias.
In his private life Zeus was quite the lothario, fathering an unbelievable number of around 100 children with many different women (but don't hate him too much – it's just a myth, after all). Of this 100, he fathered a mix of sons and daughters, many of whom were gods and goddesses, and some became great leaders.
Ganymede (or Ganymedes) was a young man from Troy. His beauty was unparalleled and for that reason, Zeus abducted and brought him to Olympus to serve as his cupbearer and lover. Ganymede's myth is an important step in the history of homosexuality.
He was the youngest, but the most powerful of three brothers. His oldest brother was Hades who ruled the Underworld. His other brother was Poseidon, god of the sea. He had three sisters including Hestia, Demeter, and Hera (who he married).
Hercules has existed long before the Marvel Universe, let alone the MCU. In ancient stories, Hercules is the son of Zeus and Alcemene (nonconsensual, which is pretty common for Zeus).
