His Parents were Cronus and Rhea. His father was a Titan and had 7 kids and ate all but two. Hades was eaten, but his brother Zeus wasn't, Zeus eventually slayed his father and freed his siblings. Out raged with the Titans all the kids who involved Hades, Zeus, and Poseidon, all defeated the Titans and took heaven. After doing so the three brothers divided up the realms and Hades was left with the dismal underworld.
Hades demanded he have a wife, more so as company than anything else. Upset that Zeus would not satisfy his demands, he abducted Demeter's daughter, Persephone. Once Demeter found out she cast a world wide perish, until her daughter was returned. Once the world was almost gone, Zeus had to step in and went to the underworld to get her back. Hades had a plan though and forced her to eat while she was there and that bound her to a contract to that she had to visit the underworld for a period of time once a year.
Hades real name is Plouton, the realm he took over was called Haides, he just took the name as his own. His brothers got the Seas, Poseidon, and the Sky's, Zeus. Even though they lived in polar opposites, the common meeting place where all past and present altercations were put aside was, Mount Olympus.
Hades character traits are greed, hatred, and sly.
Hades was very greedy in the sense that just because he was lonely by himself, he kidnapped a wife for himself. This is stated in his mythology, " Zeus betrothed his daughter to Haides without the prior consent of her mother Demeter. The god seized the girl as she was playing in a flowery meadow and carried her off to his Underworld realm. Demeter later compelled Zeus to return her for part of the year with the threat of earthly famine" (Hades & the rape of Persephone).
Hades was always furious at his brother Zeus for leaving him with the underworld while his brothers got beautiful realms. " So Haides and the overseers of the Isles of the Blest came before Zeus with the report that they found men passing over to either abode undeserving. Then spake Zeus: 'Nay,' said he, ' I will put a stop to these proceedings ( Hades and the appointment of the Judges of The Dead). This story goes on to tell of Hades and Zeus fighting over how to fix it, while Hades wanted to kill them for passing into the land of the dead, Zeus was more peaceful and wanted them returned. Hades didn't like that idea and went on a rampage and killed all who came into his realm wrongfully.
Hades was very sly and good at backstabbing the people who did him wrong." Before he died, however, (Thanatos), Sisyphus directed his wife Merope to omit his funeral rites, so that Haides, being deprived of his customary offerings, was persuaded by the cunning trickster to let him go back to life in order to complain of his wife'e neglect (Hades favor & wrath: Sisyphus). Hades saw through the trick though and he double crossed Sisyphus for killing his servant, Thanatos, and took Sisyphus down into the underworld with him.
Hades overall isn't the bad guy. He just wants to be accepted like all of us.
