Dohko serves as the Gold Saint of Libra across multiple Saint Seiya narratives, prominently in the Hades Chapter - Inferno OVA. His history originates in the 18th-century Holy War, where only he and Aries Shion survived. Athena granted him the **Misopetha-Menos**, a technique limiting his heartbeats to roughly 100,000 per year and drastically slowing his aging. This allowed him to guard the seal imprisoning Hades and 108 Specters at China's Five Peaks of Mount Lu for 243 years, outwardly appearing as an elderly man. During his vigil at Mount Lu, Dohko trained Shiryu, the future Dragon Saint, and raised an orphaned girl named Shunrei. He concealed his identity as a Gold Saint until Sanctuary forces led by Cancer Deathmask arrived. Deathmask exposed Dohko's role while trying to seize the Libra Cloth, simultaneously revealing Dohko's suspicion that Pope Shion had been replaced. When Hades' seal weakened, Dohko returned to Sanctuary. He confronted Shion, who seemed allied with Hades. Their battle triggered Dohko's **rejuvenation to his 18-year-old form** via Athena's technique. Initially disadvantaged by age, his restored youth enabled him to fight Shion evenly. He permitted Shiryu to advance through the Twelve Temples, trusting him to protect Athena despite the peril. In the Hades Chapter - Inferno, Dohko guided the Bronze Saints into the Underworld, stressing the need to awaken the **Eighth Sense** for survival. He later joined fellow Gold Saints at the Wailing Wall, devising the plan to destroy it. Drawing on his experience from the previous Holy War, he revealed that their combined cosmos could revive the divine power within their Cloths. This led to the collective sacrifice of the twelve Gold Saints, their spirits channeling energy into a single blow that breached the Wall, allowing the Bronze Saints passage to Elysium. Gravely wounded by Hades' sword, Dohko was transported to Kanon Island. Revived using **Athena's blood** administered by Gemini Deuteros, he delivered Athena's blood to her statue in Sanctuary while weakened, fulfilling a critical role in the conflict's final stages. Other media depict his younger self in spin-offs like *The Lost Canvas* and *Next Dimension*. In *The Lost Canvas*, he trained Pegasus Tenma and fought in the 18th-century Holy War, sacrificing himself to delay Hades during Hades' castle's invasion. In *Next Dimension*, his teenage self trained alongside Shion and Suikyo, later becoming the Libra Gold Saint and encountering time-traveling allies. His combat abilities feature the **Rozan Hyakuryū Ha** (Hundred Dragons Force), unleashing dragon-like cosmic energy, and participation in the **Athena Exclamation**, a forbidden attack rivaling the Big Bang's power. The Libra Cloth contains twelve weapons, which Dohko lent to Shiryu to destroy Poseidon's pillars and later wielded against the Wailing Wall.
