Pegasus Seiya

Pegasus Seiya (天馬星座の星矢, Pegasasu no Seiya?, Seiya meaning "star arrow"), also known as Seiya, is a fictional character from the Saint Seiya universe created by Masami Kurumada as the main protagonist of the media franchise, which originated in the eponymous manga written and illustrated by Kurumada, later adapted to anime, and subsequently inspiring soundtracks, OVAs, movies, video games, and other collectibles. Like most protagonists of Kurumada's works, his design for Seiya was inspired in the main character of his previous hit manga Ring ni Kakero, Takane Ryūji.

In the story, Seiya is one of the 88 mythical warriors that have served the goddess Athena during ages, protecting justice and peace on Earth, and are known as "Saints, the bringers of hope." As a Saint, Seiya dons one of the radiant and powerful armors of divine origins known as Cloths, his representing the constellation of Pegasus. He also possesses superhuman strength and speed, two of the many extraordinary abilities the Saints draw from their guardian constellations and an inner essence called Cosmo.

When Masami Kurumada was in the process of creating Saint Seiya, he gave Seiya the name Rin at first, since Kurumada was going to title his manga "Ginga no Rin" (Rin of the Galaxy). However, as Kurumada continued developing his manga, he decided to change the name to Seiya, which was more fitting. First he spelled the name with the kanji that meant "Holy Arrow", to relate it to Seiya's condition as a Saint, but later decided to use the kanji that meant "Star Arrow", to emphasize the constellation and mythological motif. Finally, he changed his manga title as well, to Saint Seiya, once he fully developed the concept of the Saints. Also, Kurumada stated that one of the first ideas he conceived for Saint Seiya was the Pegasus Meteor Fist. Since his manga was going to use the constellations as a very important and ever-present theme, he wanted his protagonist to have a special move that would be like a shower of meteors.

When Kurumada designed Seiya's likeness, he was inspired by Takane Ryūji, the main character of his hit manga Ring ni Kakero, which he created 9 years before Seiya. Most protagonists of Kurumada's works bear a resemblance to Ryūji, because Kurumada subscribes to the revered Osamu Tezuka's Star System (a stable cast of characters) technique.

The reason Masami Kurumada chose the Sagittarius Gold Cloth as the most famous of the Gold Cloths is because of its symbolism in relation to Seiya. In the Japanese language, Seiya means "star arrow", a metaphor for "meteor", and Sagittarius represents an archer, so Kurumada thought it would be a perfect match for Seiya, especially since he already had in mind that the Sagittarius Gold Cloth would eventually be worn by Seiya in certain parts of the manga. Hence, Seiya's zodiacal sign is Sagittarius, since in Kurumada's canon, a Gold Cloth bearer's sign must match the Gold Cloth he represents.
