Scorpio Milo stands as guardian of the Sanctuary’s Eighth House, taking pride in upholding the Gold Saints’ honor through combat that blends impetuous fervor with strategic precision. His signature Scarlet Needle technique targets fourteen celestial pressure points mirroring the Scorpio constellation, inflicting intensifying agony and hemorrhage, culminating in the lethal Antares strike. Though aggressive, he grants adversaries the chance to yield, preventing irreversible harm—a testament to his underlying code of honor. Born in Greece, he honed his skills on Milos Island, ascending to Gold Saint status at age seven—the youngest in recorded history—a feat underscoring his prodigious talent and unwavering devotion to Athena. During the Sanctuary conflict, he initially sided with the false Pope Saga, deeming the Bronze Saints traitors. This led him to clash with Cygnus Hyoga, whose unyielding resilience and devotion to Athena prompted Milo to recognize his own misjudgment. In atonement, he neutralized Antares’ lingering effects on Hyoga and mended the Cygnus Cloth with his own blood. The Hades Chapter revealed Milo’s maturity through his treatment of Gemini Kanon’s redemption. Initially hostile due to Kanon’s past as the Sea Dragon General, Milo subjected him to a torturous trial via Scarlet Needle to assess loyalty. Convinced of Kanon’s resolve, he formally acknowledged him as a Gold Saint, balancing duty with discernment. His longstanding camaraderie with Aquarius Camus, established in earlier sagas, proved vital during joint campaigns against Titan forces and Hades’ invading army. When confronting resurrected Gold Saints Saga, Camus, and Shura during their betrayal, Milo allied with Aries Mu and Leo Aiolia. The emotional toll of battling former ally Camus strained Milo, yet he prioritized Athena’s protection by contributing to the mutually destructive Athena Exclamation. Later, in the Underworld’s depths, Milo engaged Wyvern Rhadamanthys despite Hades’ realm sapping the Gold Saints’ power. Overpowered but undeterred, he fought until Athena’s divine intervention restored his strength, allowing him to join the collective sacrifice at the Wailing Wall alongside all twelve Gold Saints to shatter Hades’ defenses. Spin-offs expand his narrative: *Saint Seiya: Episode G* depicts a younger Milo exhibiting brashness and a competitive streak toward Leo Aiolia, maturing through clashes against Titan forces and Trojan War specters. In *Saintia Shō*, he investigates Eris-linked conspiracies, rescues Equuleus Shō, and confronts foes like the dryad Atë—side narratives emphasizing his tactical ingenuity and readiness to operate outside hierarchies when protecting the Sanctuary.
