The plot of "Saint Seiya" begins in 1986, spanning until 1990, and follows a group of five mystical warriors called Saints as they battle in the name of the goddess Athena against agents of evil who seek to rule the Earth. Their main enemy in the first arc of the story is the traitorous Gold Saint of Gemini, who has murdered the representative of Athena and taken his place as leader of the Saints. In the second arc, the Saints are confronted with the god of the sea, Poseidon, who kidnaps the mortal reincarnation of Athena and threatens to flood the world with incessant rain to cleanse it of the evils of mankind. Their final enemy, who appears in the third arc of the series, is the god of the Underworld, Hades, whom Athena has fought since the age of myth.
