Arles

Arles (アーレス, Āresu), also known as Ares, is the younger brother of Shion in the anime adaptation of Saint Seiya.

History
Arles is a powerful Silver Saint that aids his aged and ill brother in his tasks as the Pope. When a mysterious assassin attacked the Pope, Arles protected his brother, getting heavy injured, and the assassin escaped with a cut on his hand when Sagittarius Aiolos and Capricorn Shura appeared. Later, Arles noticed that Gemini Saga had the same injure, and Saga revealed his evil personality, killing Arles. Afterwards Saga takes his mask and pretends to be Arles, claiming that Saga was away watching Poseidon's activities.

When Shion's condition got worse, he appointed Arles to rule on his place until he decides who would be the next Pope. After Shion's death, Saga took control of the Sanctuary as Pope Ares, keeping his disguise until his battle against Pegasus Seiya.
