As Zeus is the youngest son of Chronos and Rhea, he has five siblings. They are Hestia, Haides, Demeter, Poseidon, and Hera. He has five uncles and five aunts who are first-Generation Titans and he is the grandson of Ouranos and Gaea. He is also the father of Apollon, Ares, Artemis, Athena, Dionysus, Hephaestus, Hermes, Iris, and many of the most well-known heroes of Hellas.
