This article comprises a list of characters that play a role in Saint Seiya (also known as Knights of the Zodiac) and its canonical continuation, Saint Seiya: Next Dimension, two manga series created, written and illustrated by Masami Kurumada.
The plot of Saint Seiya begins in 1989, spanning until 1990 (date retconned from 1986 by the author at the beginning of Next Dimension) 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.
Saint Seiya: Next Dimension acts both as a prequel and a sequel to the first series. It details the aftermath of the war against Hades and starts with Athena seeking help from the gods of Olympus and from Chronos to save Pegasus Seiya from Hades' curse by travelling back to the 18th century. The two main antagonists are the troops of the goddess Artemis, in the 20th century storyline, and the incarnation of Hades in the 18th century.
