Hades is the main antagonist of the Hercules franchise, and one of the secondary antagonists in Mickey's House of Villains. He is the ruler of the Underworld, Pain and Panic's leader and boss, Hercules's uncle and arch-nemesis, and Zeus's younger (older in original Greek mythology) brother.
He was voiced by the legendary actor, James Woods.
Hades is normally evil, cruel, selfish, cynical, ruthless, impatient, egocentric, and manipulative, but has a serious anger management problem. As an Olympian God, he is immortal and specifically has authority over the dead.
Though temperamental and destructive, he is a fast-talker and a shrewd bargainer. At some point prior to the film, he took ownership of Megara's soul as the result of one of these bargains. Hades is shown to be completely aggressive and resentful of Zeus's position as King of the Gods and makes long-term plans to overthrow and kill him.
