Knights of the Zodiac

Saint Seiya (also known as Los Caballeros del Zodiaco in Spanish, Knights of Zodiac in English and Les Chevaliers du Zodiaque in French) is one of the best series ever created. First aired in 1986, the series was not as outstandingly popular as your DBZ's or your Sailor Moon's in Japan but strangely it contains/contained an almost religious following in Hispanic (Argentina, Chile, Dominican Republic, etc) and Europ(France and Spain). Based around the idea that our modern world coexists with warriors wearing cloth/armors which are associated with constellations, the series dwells with the adventures of the saints/knights of the goddess Athena. Swearing to protect her, the Bronze saints (the main characters of the story) go to any length and fight anyone who threatens Athena or the well-being of mankind.

The series aired in Adult Swim for a while in a crappy time slot and has never really developed an American audience, which is a shame.I can not stress enough how good the series is.
