Hades (/ˈheɪdiːz/; Ancient Greek: ᾍδης, romanized: Hā́idēs, Attic Greek: [háːi̯dεːs], later [háːdeːs]), in the ancient Greek religion and mythology, is the god of the dead and riches and the King of the underworld, with which his name became synonymous. Hades was the eldest son of Cronus and Rhea, although this also made him the last son to be regurgitated by his father. He and his brothers, Zeus and Poseidon, defeated, overthrew, and replaced their father's generation of gods, the Titans, and claimed joint sovereignty over the cosmos. Hades received the underworld, Zeus the sky, and Poseidon the sea, with the solid earth, which was long the domain of Gaia, available to all three concurrently. In artistic depictions, Hades is typically portrayed holding a bident and wearing his helm with Cerberus, the three-headed guard-dog of the underworld, standing at his side.
Roman-era mythographers eventually equated the Etruscan god Aita, and the Roman gods Dis Pater and Orcus, with Hades, and merged all these figures into Pluto, a Latinisation of Plouton (Ancient Greek: Πλούτων, romanized: Ploútōn), itself a euphemistic title (meaning "the rich one") often given to Hades.
Hades is the main antagonist of Disney's 1997 animated feature film Hercules. He is the fast-talking god of the Underworld, known for having a fiery temper and a vendetta against his oldest brother, Zeus. Over the span of eighteen years, Hades developed a scheme to take over Mount Olympus and the cosmos, but a prophecy by the Fates foretold that a hero would rise against him and end his reign.
While the Hades of Greek mythology was not particularly malevolent, the Disney version portrays him as an evil figure, albeit comedic. This interpretation of the character proved successful, making Hades one of Disney’s most popular antagonists, and a primary member of the Disney Villains line-up.
