Berserkers (Saint Seiya)

The Bersekers of Ares were a powerful army in the story of the Saint Seiya series, but, never were shown in an anime.

They were warriors that were killed in the Athena's Coliseum, and after, become ghosts that with Ares, tried defeat Athena in a holy war. The Bersekers, almost defeated Athena's army, so, she allowed the Libra Weapons to be used and with this, Ares was defeated and the Bersekers were sealed under the Coliseum.

They are bloodthirsty, use weapons to fight, and have some women between they, because Enyo is a goddess.
