Zeus is then mentioned by the god of sleep Hypnos in vol.28 of the manga, who refers to him as the ruler of the Olympian Gods. He is mentioned again by Gold Saint Gemini Saga in further volumes of the manga, who schemed to seize Athena's Niké Staff to overthrow Zeus, Hades, and Poseidon to take over their realms and conquer Earth, becoming the supreme ruler of all realms. He is first mentioned in vol.1 of Kurumada's manga, as the father of Athena, who sprung out of Zeus' head in full battle armor, in the same way as she did in Greek mythology. Zeus has had a limited participation in the Saint Seiya universe to date, which is virtually reduced to referrals by name, both in the manga and the anime adaptation.

1 Appearances in the Saint Seiya universe.

Although Zeus has never made an appearance physically in Kurumada's manga, he has been mentioned or referred to in several occasions. Masami Kurumada has spoken about Zeus in interviews about his future plans, but he hasn't revealed much since the Heaven Chapter of his manga is still in development. A new chance to publish it came in 2004 when Kurumada decided to publish the Heaven Chapter in anime format instead of a manga written and drawn by him, and it was given a start with the Saint Seiya Tenkaihen Josou Overture movie. Kurumada had planned to make Zeus appear in the fourth act of his manga, but he was forced to put the manga in hiatus in 1991 after the Hades arc due to a decrease in popularity, delaying the publishing of the Heaven Chapter until the time was ripe. In Next Dimension official sequel of the manga Saint Seiya, it is revealed that Zeus lives on Mount Olympus, and it is stronger than his two brothers Poseidon and Hades.

In Kurumada's mythos, Zeus has been described as the Sovereign of Heavens, and father of Athena. Although the character has remained in development for a long time, he was created by Kurumada based on the mythologic persona of the same name. The Greek god Zeus (天帝ゼウス, Tentei Zeusu, tentei meaning 'Sovereign of the Heavens') is one of the deities expected to be featured in the near future, in the universe of the Manga Saint Seiya.
