Shun's character design and DD breasted armor were so confusing to foreign producers that, in the French version, he was dubbed by a female voice-actress in the first four episodes of the Galaxian Wars in the Sanctuary Arc.
Although it's never mentioned in the anime, the manga readers know that Mitsumasa Kido has fathered the 100 so-called 'orphans' that he later pretends to foster before training and sending them all over the globe to earn Armors and become Saints. The Bronze Saints are all half-brothers with the exception of Shun and Ikki who have the same mother.
This series gained cult following in Brazil and remains as one of the most successful anime aired there, tied with the Dragon Ball series. A national soundtrack was released in 1995 featuring vocals of singers William Kawamura and Larissa Tassi, who also recorded the Brazilian soundtrack for Magic Knight Rayearth (1994).
Camus, the Gold Saint of Aquarius is one of the few French Saints (the other notable one is Misty, the Lizard Silver Saint) and his name is a nod to the Algerian born French playwright, novelist and essayist author of the Stranger.
The anime-only Bronze Cloth designs eventually gave way to armors that were faithful to the manga. As the battered Bronze Armors were repaired/revived with the surviving Gold Saints' blood after the Battle of the Sanctuary, their design changed to replicate the one Kurumada had intended for his Poseidon Arc. However, as this arc was still being drawn and edited when the TV anime resumed its airing, the Asgard Arc was written as an anime-only arc to fill the gap.
As a general rule, the Armor design is meant to reflect the Saint's position in the Saints' hierarchy. Bronze Armors are scanty, Silver Armors (with the exception of Eagle and Ophiucus) cover more of their wearer's body, Gold Armors leave very few body parts unprotected. In the manga, every time the Bronze Cloths are revived with blood, their design evolve to a more elaborate one, covering more and more of the Bronze Saint's body. However, the anime Bronze Armors of the Sanctuary Arc were so elaborate they were more akin to Silver Armors. As the TV show endorsed the manga's second Bronze Cloths (3rd for Shiryu and Seiya) design, the anime viewers found their favorite characters wearing scantier armors after the Battle of the Sanctuary.
Although Mu states that only blood can revive a dead Cloth/Armor, there is one notable exception: the Phoenix Cloth. Just as its mythical namesake, this Armor can regenerate itself, even when reduced to ashes. Furthermore, it seems that it lends its regenerating powers to its bearer thus granting immortality to the Phoenix Bronze Saint. It's also interesting to note that, if Bronze Cloths are worn through the centuries by generations of young Saints, before Ikki , no man had either claimed, earned or worn the Phoenix Cloth, ever.
Ikki, the Phoenix Saint, is an exceptional Saint in many regards. Notwithstanding the fact that his Armor grants him virtual immortality and the fact that he's the first man ever to win the Phoenix Cloth, Ikki's a powerhouse among the other Bronze Saints. As the anime's first villain, he easily takes on the other 4 Bronze Saints at the same time; later his powers and abilities enable him to defeat Silver Saints with ease. He also is a psychologically complex character, scarred by a traumatic training but yet a loving and protective brother to Shun. His maturity and long term strategic choices put him at odds with the other, often hot-headed Bronze Saints. Even though he doesn't team up with the quartet, he still manages to show up at the right time and at the right place to save the day.
A few Saint Seiya characters were anime only characters. One of the most interesting is Crystal Saint whose Armor design stood out (maybe because he might be a retired Saint whose Armor is not linked to any constellation) and who is Hyoga's Master in the anime. During the Battle of the Sanctuary, Hyoga reveals that his master's master is none other than Camus, the Aquarius Gold Saint. However, in the manga Hyoga's master is Camus. The manga canon about this relationship is endorsed from the Hades Arc anime on.
This series became so popular in Brazil that Nobuo Yamada, who sings the title theme, has been in Brazilian anime conventions and has performed the Brazilian-Portuguese version, originally sang by Eduardo Falaschi.
