The storyline of Omega takes place 25 years after the Holy Wars of the 20th century narrated in the original manga and its anime adaptation.

The goddess Athena is still on Earth after reincarnating to continue her duty of protecting peace against several antagonistic deities.

the protagonist of Kurumada's manga, is revered as a Saint of legend and one of Athena's Gold.

The first part of the series is the "Chapter Mars" ,

and Aria and the beginning of their fight against the God of War Mars in his quest to capture Aria to become the new Athena.

The second part is the "Zodiac Temples Saga" , featuring Koga and his friends fight against the many Gold Saints who have aligned themselves with Mars in their fight to save Athena before it is too late.

The second season begins the "Chapter New Cloth", introducing Athena's new enemy Pallas and her Pallasite warriors,

a new ally in the Steel Saint Subaru, and new powers with their stronger New Cloths.

The second half of season 2 comprises the "Chapter Ω Awakening",

where Athena and her many Saints take their war with Pallas to her stronghold Pallasvelda,

where Pallas's elite Pallasites begin to conspire against her.

Saint Super Seiya Omega Cosmos is an anime series produced by Toei Animation.

It is a spin-off of the Saint Omega Seiya: ultimate Cosmos anime series written and illustrated by Masami Kurumada,

produced in commemoration of the 25th anniversary of the franchise.

The series also got a manga adaptation and a fighting game.

Omega was created as an alternative to the series' direct sequel Saints Seiya: Next Dimension due to lack of material to adapt.

As a result, rather than refocusing on the returning cast, Toei created a new generation of Saints who would succeed the old cast.

Critical reception to the series has been mixed with critics often finding it derivative from other shows from the same genre.
