The god who rules the Underworld , and Athena’s true enemy.
Aided by the fearsome Hypnos and Thanatos, his closest subordinates. Both Hades and Athena have engaged each other in a long standing conflict for domination of Earth, that spans across millennia, sparking bloody Holy Wars in the ages of myth, the 15th, 18th and 20th centuries.
Hades, whose beautiful body is the spawn of the union between Cronus and Rhea , was subjected to a traumatic experience in the ages of myth, when he was gravely wounded by Pegasus Seiya’s incarnation in that era. Thus, Hades decided to put his true body to rest in the unreachable Elysion, until his dominion over Earth is secured. To be able to incarnate, Hades then chose the body of the purest human in the era of his return, as a host for his divine soul, being Alone his chosen vessel during his incarnation in 1747, and Andromeda Shun in 1990.
The god of the Underworld was defeated by Athena and her Saints in each of his incarnations, at the high cost of the Saints’ lives and havoc over the land. Particularly bloody have been the encounters between the deities in the 18th and 20th century. During the latter, Hades retreats to shelter himself in the Underworld, believing himself safe from Athena and her Saints, who devise a way to invade Underworld.
Determined to achieve domination of Earth whatever the cost, Hades unleashes the Greatest Eclipse phenomenon on Earth, which would conceal the sun, turning the planet in a gelid graveyard and exterminating all life. Against all odds, Hades is later rejected by his chosen vessel Shun, and retreats to the Elysion and captures Athena and places her in the lethal Great Amphora, assuming the Saints would never be able to trespass the Wailing Wall in time to save their goddess’ life. He is proven wrong by the Saints’ tenacity, and the ruler of the Underworld is forced to revive his true body, dormant for millennia since the ages of myth, and engage the Saints in a final duel to the death, during which Hades is shocked to encounter his feared enemy from the ages of myth reincarnated in Pegasus Seiya. Athena, freed from the Amphora joins her Saints in the battle, and after a brief but costly battle, against all odds, Hades is finally defeated. The mortal world is saved from the Greatest Eclipse and the Elysium collapses, but Seiya was also defeated in the battle, being pierced in the heart by Hades’ sword and put into a curse which kept him in a catatonic state.
In the manga sequel Next Dimension , Hades is incarnated in Alone’s body, a boy that as Shun, has the most pure body of the Earth.
