He is a close friend of Libra Dohko, the only survivor of the last generation of saints together with Shion.

Plot overview
Prior to the start of the main story, Shion served as a Saint on the previous generation of Athena Saints. In the beginning of the war against Hades, Shion was promoted from Bronze to Gold Saint of Aries. Under the guidance of Athena, gold saints Aries Shion and Libra Dohko set out to lead the saints in an invasion of Hades' domain, the World of the Dead. Much of the war ended in bloodshed and annihilation, with the saints having to resort to the Libra Weapons -- a move that Athena herself normally frowned upon. There were no doubt many casualties in this war—both saints and Specters alike. The last two survivors of this struggle were the Gold Saint of Aries and the Gold Saint of Libra. After the war, Dohko would be assigned with the task of watching over the seal on the souls of Hades' 108 Specters, while Shion would go on to become the new Grand Pope of the Sanctuary, with the main duty of preparing new blood for the next Holy War.

The sanctuary saga
Upon becoming the Grand Pope, Shion could no longer perform the duties of the Aries saint as he had previously done - thus, he began to train an apprentice to succeed the cloth. Shion found that successor in Mu, an extraordinary young man of the same race as Shion with a natural talent for cloth reparation. Mu not only became the new Gold Saint of Aries, but he did so with all of Shion's abilities under his belt.

After Athena had once again reincarnated into a human infant, Shion began preparations for the inevitable war. He understood that, with old age, his own time would soon be up, and therefore needed to choose a successor for his seat. With the exception of Sagittarius Aiolos and Gemini Saga, all of the gold saints were too young and inexperienced to take up the responsibilities. After a lengthy time of consideration, Shion eventually settled on the Gold Saint of Sagittarius. While Aiolos was not as powerful as Saga, Shion felt confident in his choice because he knew of Aiolos' undying loyalty to Athena.

Unfortunately, Shion was confronted by Saga in regards to his decision shortly after the announcement. It seems Saga felt discontent at Shion's choice, and demanded an explanation for it. Shion revealed that, while he acknowledged that Saga had a heavenly reputation and was the more powerful of the two, he could not help but sense something terrifyingly dark within the Gemini Saint. It is at this point that Saga confirmed Shion's suspicions, and assaulted the weary Pope with a deathblow.

The Hades
In Meikai, the realm of the dead, it was announced that Hades would attack the Sanctuary and unleash the Greatest Eclipse on the World, this left the dead saints in a predicament, because they were dead and unable to do anything, but opportunity rose when Hades told them that, if they killed Athena they would live again then, not even death could keep Shion away from aiding Athena in her Holy War against Hades. Even after years since his assassination, Shion returned from death to help Athena and the current saints with a way to get into the World of the Dead. Originally, it was assumed that Shion, along with other deceased saints such as Saga, Shura, Camus, Deathmask, and Aphrodite, had sold their soul to Hades and returned to Sanctuary to kill Athena. It turns out that this was a grand scheme by the former Pope and the dead saints in order to get a message to Athena—that she must die to awaken her cloth the 8th sense if she hoped to successfully defeat Hades within his domain.

After the message had been delivered, Shion met with Seiya, Shiryu, Hyoga, and Shun to inform them of the truth of what had taken place with the gold saints and Athena. Perhaps as a nod to his apprentice's talents for armor reparation, Shion instantly restored all four saints' individual cloths using the blood of Athena. Finally, with his last act as the Grand Pope, Shion commanded the young bronze saints to invade the World of the Dead—they shall not stop until every Specter has been defeated, and Hades himself is on his knees.

In the manga, it is at this point that Shion's restored body gave way and the former Aries perished into dust. In the anime the event is depicted in the same way, although Shion lasted until near sun rise; prior to disappearing for good, Shion once more united with old friend Dohko to share past times.

Power and abilities
As a former Gold Saint, Shion has fully mastered the 7th sense, what gave him great power and the ability to move at the speed of light. Shion is among the most powerful of Athena's Gold Saints.

Shion is naturally gifted with great psychic powers that allow him to have great control over telekinesis, telepathy and even teleportation. He is also able to make and heal holy armors using stardust, a role that was always reserved to those of Lemuria.

Shion can create a transparent, glass-like barrier between himself and an object called Crystal Wall (クリスタルウォール, kurisutaru wōru?) The wall is very durable, and has been shown to shield against everything from normal cosmos attacks to poison scent. The strength of the wall is dependent on Shion's cosmos level. The shield not only protects Shion but repel any form of attacks with the same power against his opponents. Saint Seiya: The Lost Canvas also shown Shion using the Crystal Wall to create a defensive barrier with the form of a cube.

His offensive technique is Stardust Revolution (スターダストレボリューション, sutādasuto reboryūshon?), in which Shion burns his Cosmo energy to create a universe thus summoning stardust from stars and galaxies that throws innumerable blows instantly. It's well known that the attack has force of shooting stars and comets and obliterates an enemy with raw cosmos power.

Cloth, Constellation and Temple
Although Masami Kurumada revealed in his prequel manga Saint Seiya Next Dimension that Shion was originally a Bronze Saint, the guardian constellation awarded to him later was Aries and his Gold Cloth represents it and its associated myth : the winged Ram that saved the boy Phrixus and his sister Helle, and later, the Ram's skin was known as the Golden Fleece, and found by the legendary Jason of the Argonauts.

The temple Shion guarded was known both in manga and the anime adaptation as Hakuyōkyū, literally the "White Ram Temple".

Shion's original guardian constellation as a Bronze Saint has yet to be revealed by Kurumada.
