Saint Seiya Aries: How Powerful is Master Mu as the First Sage?
In the expansive universe of Saint Seiya, the character of Aries Mu stands out with his unique charisma and formidable power. As a descendant of the Jamir tribe, he is often seen working tirelessly to repair the Cloths of fellow Saints—earning him the respectful title of Master Mu.
The Legacy of a Golden Saint
Born in the mystical highlands of Tibet, Mu inherits the bloodline of the Jamir Plateau. He was the prized disciple of the previous Aries Gold Saint, Shion. Guarding the first house of the Zodiac, Mu’s strength is beyond question. Trained personally by Shion, he commands an arsenal of extraordinary techniques, including Teleportation, Crystal Wall, and Starlight Extinction.
Master of Psychic Power and Defense
Mu’s psychic abilities are unparalleled among his contemporaries. His Crystal Wall is renowned as the ultimate defensive technique—so powerful that even the combined efforts of the “Marine Duo” (Cancer Deathmask and Pisces Aphrodite) could not breach it. His signature move, Starlight Extinction, was self-taught, though later adaptations in the series created minor continuity questions—a common trait in long-running manga narratives.
A Strategist and a Guardian
When Saga impersonated the Pope and seized control, Mu was among the first to detect the deception. His attempt to confront the false Pope was rebuffed, leading him to retreat to Jamir. Some viewed this as self-preservation; others, as disillusionment with the Sanctuary’s corruption.
Everything changed when Seiya and his friends—the Bronze Saints—sought his help to repair their Cloths. Inspired by their dedication to saving Athena, Mu realigned himself with justice. He not only repaired their armors but also became their mentor and protector. He was the only Gold Saint who did not obstruct the Bronze Saints’ path through the Zodiac Houses. Instead, he empowered them—most notably guiding Seiya toward awakening his Seventh Sense.
Unwavering Loyalty and Hidden Strength
Mu’s influence extended beyond mentorship. When Phoenix Ikki was lost in another dimension after battling Saga, it was Mu’s immense psychic power that retrieved him. Throughout the series, Mu remained a steady, principled figure in a generation of Gold Saints plagued by infighting and inaction.
During the Poseidon arc, when most Gold Saints remained passive, Mu was consistently among the first to act in defense of Athena. His loyalty never wavered, which may explain why—in the aftermath—Athena revived the Bronze Saints, her most devoted defenders.
How Strong Is Mu, Really?
Mu’s full power remains one of the series’ intriguing mysteries. He rarely engaged in full combat, but his performance in the Hades Chapter suggests he ranks among the top Gold Saints. His impenetrable Crystal Wall and superior psychic skills place him above mid-tier fighters like the Marine Duo, yet he may fall slightly short of transcendent beings like Saga and Shaka.
In many ways, Mu represents a power benchmark within the Gold Saints—a bridge between raw strength and strategic wisdom. His value isn’t just in his techniques, but in his clarity of purpose, his integrity, and his role as a guardian of both hope and heritage.
So, how powerful is Aries Mu? He is powerful enough to change the course of battles without always throwing the first punch—a sage, a protector, and one of the most compelling figures in the world of Saint Seiya.
