I cavalieri dello zodiaco

Saint Seiya is the best anime ever, it's about 5 young warriors "The Bronze Saints" who defend the reincarnation of Godess Athena (Saori Kido) against threats such as the "Silver Saints" and the deadly "Gold Saints" (the zodiac signs, from aries thru pisces) in which the bronze saints come out victorious, and with the 5 remaining gold saints alive as their allies, who repair the heroes' destroyed armors

Then comes the Asgard saga, where the heroes have to fight against the threat of a corrupted Hilda Polaris (the representation of Odin on earth) and her 7 god warriors

And the 3rd part of the series, the heroes fight Poseidon and his 7 marines to protect not only Athena, but the whole world..

The series are great, the characters (in my opinion) is what makes a show (or an anime) great, and in saint seiya all the characters are awesome, both in apperiances and personalities... I really can't choose who my favorite character is, they're all cool... but one thing is for sure: this is my favorite anime of all the time!
