Saint Seiya (1986)

The Sanctuary of Athena in Greece is where children are trained to become Saints of Athena. These warriors each possess a different cloth that represents a particular constellation, and they've sworn an oath to protect the latest reincarnation of the goddess Athena. If Athena falls, so will the world — and that makes them the last guardians against the apocalypse. Seiya is a young Saint who arrived as a child and now possesses the Pegasus Cloth. He's in search of his sister Seika, and the best way to find her is to compete in the Galaxian Wars. But when things go wrong, Seiya is forced to recover a cloth from the hands of sinister forces.

Saint Seiya is an action show featuring Toru Furuya and created by Masami Kurumada.

Saint Seiya is currently streaming for free (ad-supported) on Plex and Plex Player and it's also available on Crunchyroll.
