Libra Dohko survived the previous Holy War against Hades alongside Aries Shion, receiving the divine gift of Misopetha-Menos. This method reduced his heart rate to roughly 100,000 beats per year, enabling him to live for centuries while aging only 243 days over 243 years. As a condition, he guarded Hades' seal at the Five Peaks of Mount Lu in China, awaiting the deity's resurgence. During his vigil, Dohko adopted an orphan girl named Shunrei and trained Dragon Shiryu as his primary disciple. He taught Shiryu the Dragon Saint's martial arts and philosophical lessons on courage and justice, which Shiryu later applied in pivotal battles. Dohko distanced himself from the Sanctuary, suspecting Pope Shion had been compromised. His seclusion ended when Cancer Deathmask arrived to claim the Libra Gold Cloth, forcing Dohko to reveal his Gold Saint identity to Shiryu. When Hades's forces threatened Sanctuary anew, Dohko departed Mount Lu. The lifting of Misopetha-Menos restored his youth and combat strength. He joined the surviving Gold Saints in defending Athena, confronting resurrected allies like Shion. Dohko witnessed betrayals by Gold Saints and fought Hades's commanders. He sacrificed himself by intercepting Hades's attack to enable Athena's escape, the blow piercing his heart. His body, afflicted by the "Flame of Soul Wound" from Hades's sword, was recovered and taken to Kanon Island, where he remained unconscious. Dohko's combat prowess centers on Rozan martial arts. His techniques include Rozan Shō Ryū Ha (Rising Dragon Punch), Rozan Ryū Hi Shō (Dragon Flying Strike), Rozan Kōryūha (a suicidal space-carrying attack), and Rozan Hyaku Ryū Ha (Hundred Dragons Attack), unleashing countless dragon-shaped Cosmo bursts. He masters the twelve weapons within the Libra Cloth. Gemini Saga declared him the strongest Saint, citing raw strength that withstood Shion's Stardust Revolution. Dohko analyzes and counters opponents' moves after a single observation. In the spin-off *The Lost Canvas*, set in the 18th century, Dohko appears as a young Gold Saint investigating Specters in Italy. He mentors Pegasus Tenma, fights alongside Shion during Hades's invasion of Sanctuary, and assaults Hades's castle. Here, he combines Rozan Hyaku Ryū Ha with Tenma's Pegasus Meteor Fist against Hades, though unsuccessfully. Dohko dies from Hades's sword. In *Next Dimension*, young Dohko trains alongside Shion and Crateris Suikyo. He encounters a time-traveling Shiryu, entrusting him with Athena's protection. Dohko later battles Suikyo, now the Specter Garuda, resulting in Suikyo's apparent death.
