Sagittarius Seiya (Omega)

Sagittarius Seiya (射手座（サジタリアス）の星矢 Sajitariasu no Seiya?) the Sagittarius Gold Saint in era of Omega. Seiya can use the element of Light.

Background
Formely, the wearer of the Pegasus Bronze Cloth, he is now regarded as a Legendary Gold Saint in the millieu of Omega. Having defended Athena in the past from powerful enemies, Seiya still continues his mission to protect Athena/Saori assisted by the Sagittarius Gold Cloth.

First Battle Against Mars
During the period of peace that followed after the Holy War against Hades, the War God Mars and his army of warriors called Martians invade the Earth and fight Athena and the Legendary Bronze Saints. Seiya, officially wearing the Sagittarius Gold Cloth, and his companions stand to defend the world once more.

During the fight, a meteor, for unknown reasons, fell on the battlefield, momentarily ending the threat posed by Mars. This meteor brought with it a mysterious power, which resonated with the Athena's Cloth. This collision caused a change in the Saints cloth, which enabled the Saints the ability to use one of eight elements, and changed the Cloths into small gems called Cloth Stones. A new era of the Saints had begun.

Second Battle Against Mars
Unfortunately, for the Saints, the meteor also granted Mars and his army with new power. With his new Cloth "Galaxy" and the ability to control the element of Darkness, Mars and his warriors return to face Athena and the Saints again.

With this new power Mars attacked Sanctuary in hopes of trying to capture Saori, who was taking care of the infant who would later become Pegasus Kōga. He attacks Saori, inflicting her with a mark of Darkness, but before he could continue, Seiya intervenes. Seeking to defend Athena and Kouga, Seiya faces the God of War in combat. In the clash, Mars manages to break parts of the Saggittarius Gold Cloth, but Seiya is still able to compete with the God of War in power. Finally, with the arrival of the rest of the Legendary Bronze Saints he manages to win and seal Mars, but the seal will not last forever.

Because of the power of Darkness Mars has attained, during their battle, most of the Saints who directly faced him acquired Brands of Darkness, which prevents whoever is branded with the inability to burn their Cosmo or risk being comsumed by the darkness, effectively prevented them from fighting. Although not confirmed it is reasonable that Seiya probably also acquired a Brand of Darkness, which might be a basis for his dissapearance.

Third Battle Against Mars
During the brief period of peace that came after the seal of Mars, Seiya disappears. Thirteen years later, Athena delivers the Pegasus Cloth to Kouga. Mars finally breaks free from his seal and goes to capture an unprotected Athena. Seiya, in turn, uses his Cosmo to teach Kouga, the Pegasus Ryu Seiken and explains to him more about his Cosmos.

While attempting to rescue Aria and Saori in Sanctuary, Leo Mycenae and Mars are able to defeat all the young Saints of Palestra. About to end the life of Kouga, Mars is stopped by the brief return of Sagittarius Seiya, to the surprise of God, who soon notices that his power is nearing its end.

With his last bit of strength, Seiya is able to again confront Mars, and to protect the young Saints, causes a big explosion with his and Mars clash of powers. With the intervention of Seiya, the young Bronze Saints escape with their lives from the Tower of Babel.

Seiya is then seen again after the destruction of the Wind Ruin. Using his last remnants of Cosmo, Seiya manages to send a message, by the constellation Pegasus, to Kouga and the other Bronze Saints telling them that "To you I entrust Athena". After the message, Medea relates to Mars that Seiya's Cosmo has completely faded.

Seiya's Return
The "Final" battle to save the Earth led the Bronze Saints to Mars, where Kōga finds himself possessed by Abzu, the God of Darkness. In turn it is revealed that Seiya was being imprisoned for an indeterminate time in the depths of the red star, with his body covered and chained in Brands of Darkness. Mars, regretting having been consumed by the darkness, protected Seiya so that Abzu wouldn't possess him. He had kept Seiya alive to serve as a last resort, to continue the fight against the darkness in case he was no longer able to contain it.

With the cosmo of Aquila Yuna, Lionet Sōma, Dragon Ryuho, Wolf Haruto and Orion Eden, combined with the remnants of Athena's scepter, the chains binding Seiya are broken. Seiya hastens back to the surface and prevents Abzu from killing Saori. With the help of Yuna, the only Bronze Saint to be standing still, they finally managed to release the Pegasus Saint from Abzu's possession.

Unfortunately, the respite is short-lived. Abzu left the scene and kidnapped Saori. Seiya gives the Sagittarius Gold Cloth to Kōga who is the only Saint still untouched by the darkness, to pursue the God and put an end to the battle. When Koga manages to free Athena, he throws her to the ground before Abzu can retake her. Seiya is the one who catches her, truly reuniting the two. Finally, once Koga defeated Abzu, rain pours light on the blue planet, purifying people with Brands of Darkness. Saving the world.

Seiya Mission to Eliminate Pallas
After the struggle against the god of darkness, a new danger threatens Athena. Her younger sister, the goddess Pallas, is about to make his comeback on Earth. Order of Saori, Seiya from the murder, armed with the famous golden dagger. However, he meets a girl on the spot in tears, ready to accept the fatal sentence. Torn between his duty and his feelings, the Gold Saint can not finally resolve to lay hands on a child. It is this point that the Pallasite Titan. After a brief scuffle, the latter carries the child, leaving Seiya alone with his remorse. His hesitation is about Athena and her Saints lead to a new war.

Sanctuary
Once back at the Sanctuary, Seiya joined Athena to apologize. Still marked by what just happened, Seiya no longer judged worthy to be with him as Saint. Saori finally managed to comfort him and asked him to forgive her for having faced such an experience. The Saint and his goddess mutually cause of concern as they stand to each other. Appeased Seiya renews his oath and promised that he will protect Saori. Promise that the Gold Saint reiterates shortly after to Kōga during his visit to the Sanctuary.
