Hades commands the Underworld as its sovereign, leading legions of Specters in cyclical wars against Athena. Reincarnating every 243 years, his true divine essence remains anchored in Elysion, guarded by twin deities Hypnos and Thanatos. To evade vulnerability, he possesses human hosts of pure lineage—such as Andromeda Shun—transfiguring their bodies to mirror his pallid skin, raven hair, and piercing green eyes while briefly preserving their consciousness.

His crusades against humanity stem from an unshakable belief in divine superiority, condemning mortals as flawed beings deserving eradication under the pretense of cosmic purification. This ideology fuels his relentless assaults, yet his rivalry with Athena reveals contradictions; he spares her repeatedly while annihilating her Saints without mercy. A master manipulator, he binds followers through illusions of immortality, weaponizing their faith to advance his goals.

Among the eldest Olympians, Hades wields dominion over death, wielding telekinesis, extrasensory perception, and the resurrection of fallen warriors. Even in mortal vessels, his combat prowess crushes waves of Saints. The "Greatest Eclipse," capable of erasing souls across the solar system, epitomizes his apocalyptic power. His near-immortality demands the combined force of Athena and Saints clad in God Cloths to breach his defenses.

Victorious in the Titanomachy alongside Zeus and Poseidon, Hades claimed the Underworld throne. His surplice, stored in Elysion, merges celestial elegance with menace—silver-gray armor adorned with wings contrasts his ruthless nature, masked behind a visage of serene beauty.

His final defeat transpires when Bronze Saints penetrate Elysion’s guardians. Athena’s tactical sacrifice and reclaimed Cloth ignite a climactic battle, embodying mortality’s defiance against divine tyranny. Though his soul is sealed, remnants of his influence permeate spin-offs like *Next Dimension*, where unresolved vendettas and lingering followers perpetuate his dark legacy.
