The Scorpio Gold Cloth is the cloth of the Saint Milo in Saint Seiya, Soul of Gold, and Saint Seiya: Episode G, and Kardia in Saint Seiya: The Lost Canvas. It is of the highest class of the cloths that Athena’s Saints wield, the Gold Cloths.
The Scorpius constellation was based on the Scorpion sent by Gaea when Orion threatened to kill all beasts of the Earth. In another version of the myth, Apollo sent the Scorpion after Orion to protect his sister’s purity. In both versions, the Scorpion was sent to the skies as a constellation for its service.
Milo trained to be a Saint in Milos Island (Greece), years before the birth of the modern Athena, by an unknown master. The cloth was likely kept in Sanctuary until a Saint worthy of wearing it was found. Milo first appeared in volume 7 of the manga, under the summons of the Pope. He was supposed to have been sent to hunt the Bronzes, but was instead kept in Sanctuary, while he revealed suspicion of the Pope’s identity. He eventually would fight Hyoga, and was able to deal a nigh deadly blow, at the cost of his armor being frozen. He sparred Hyoga, and admitted defeat. Later, during the invasion by the Specters, he would use the Athena Exclamation against the invading dead Gold Saints. He was eventually trapped in Hell when trying to help the Bronzes get to Hades. He returned from being frozen in Cocytus, and combined his powers with the other Gold Saints to destroy the Wall of Lamentations, dying in the process.

During the course of the trip, he has to face Wyvern Rhadamanthys, and shows new techniques, pushing his body to the limit during the fight to kill Rhadamanthys. Dégel attempts to help him, but Kardia’s body gives out shortly after they leave, a red nail all that is left to symbolize him.
