As a Saint, Seiya has been trained in mind and body to learn how to use the power of the Cosmos within his own body and use it for super strength, speed, agility, durability and reflexes. The Pegasus Cloth armor he wears represents the Pegasus constellation, which is associated with Pegasus, the divine winged horse from Greek mythology; which protects his body even more. Seiya trained for six years and defeated ten other trainees to obtain the Pegasus Cloth and the status of Saint of Athena. The Pegasus Bronze Cloth is damaged various times throughout the series, with Aries Mu typically responsible for repairs. In the manga, the Cloth changes appearance each time it is fixed, while it remains the same in the anime adaptation until the series' second arc. After the Gold Saints use their blood to revive the Bronze Cloths at the end of the Sanctuary arc, the Pegasus Cloth takes on a golden hue whenever Seiya charges his Cosmo to the maximum. The version of the Cloth that Seiya uses in the Hades arc possesses wings that allow him to fly, both normally and through dimensions. During Seiya's fight against Thanatos, it reaches its God Cloth state, which was last seen in the ages of myth and further increases Seiya's Cosmo and vitality.
Several anime and manga publications have provided both acclaim and criticism of Seiya's character. DVDVerdictReview.com describes Seiya as poorly developed, wholly characterised by his affiliations and connection to a constellation. DVDVisionJapan comments on Seiya's interesting character and praises voice actors Tōru Furuya and Illich Guardiola for adding emotion and passion into his character. Anime News Network, on the other hand, comments that Seiya's voice actor for the English dub is unsuitable, that he enunciates strange words and does not sound at all heroic. They also criticized Seiya for being an "underdog" in most battles. Chris Beveridge from AnimeOnDVD found that Seiya was overshadowed by his comrades in the anime's tenth DVD but still found the other characters made the DVD appealing. In a review of the series, writer Jason Thompson notes one of Seiya's early fights against the Black Saints ends with one of the most painful scene as Seiya's blood is contaminated and later his friend Shiryu has to heal him by removing all of his blood. Additionally, Thompson noted that Seiya's speech in the series' last arc regarding how he blames gods for humanity's problems, to the point of being noted as "atheism or anti-theism" comparing him with the 2010 film Clash of the Titans. Mark Thomas of the Fandom Post criticized Seiya's overuse of his Meteor Fist as he tends to repeat in all of his fights even when his enemies manage to block it. In a review of Legend of Sanctuary, Screen praised Seiya's comical characterization as well as the performance of the Pegasus Meteor Fist technique. GamerFocus complimented the way Seiya and his friends were handled in Saint Seiya Omega as while the protagonist, Pegasus Koga, stars alongside a new group of Saints, Seiya's actions do not take the spotlight. 2b1af7f3a8
