Dohko holds the title of Libra Gold Saint, distinguished by profound wisdom and extensive combat experience. As one of only two survivors of the 18th-century Holy War against Hades, alongside Aries Shion, Athena granted him the longevity technique Misopetha-menos. This technique drastically slowed his aging, enabling him to await the next conflict stationed at China's Five Old Peaks of Mount Lu. After the historic war, Dohko assumed guardianship over the sealed prison of Hades' Specters. He took in the orphaned girl Shunrei, providing her shelter at his mountain residence. His role evolved into mentorship, most notably training Dragon Shiryu in sacred combat and cosmic manipulation. Throughout Shiryu's development, Dohko emphasized philosophical principles alongside physical discipline, forging a deeply paternal bond Shiryu often recalled in critical battles. Initially appearing elderly, Dohko radiated serenity and strategic insight honed over centuries. His physical rejuvenation during the Hades conflict revealed a more vibrant and assertive disposition reminiscent of his youth, though his vast experience tempered his actions, blending historical perspective with renewed vitality. Dohko's involvement proved strategically indispensable in the Hades crisis. Departing Mount Lu for Sanctuary, he confronted his possessed former comrade Shion. Their battle became both diversion and test of mutual understanding, concluding when Dohko discerned Shion's underlying intentions. He then entrusted Shiryu with the advanced technique Rozan Hyakuryu Ha and sanctioned his participation in the perilous campaign against the Underworld. His historical knowledge later proved vital when Athena's forces encountered the Underworld's impenetrable Wailing Wall. Dohko deduced that only the collective sacrifice of Gold Saints, using their revived Cloths' divine blood, could destroy the barrier. This revelation prevented unnecessary casualties and redirected the surviving Gold Saints toward their ultimate act of valor. Canonical prequels and spinoffs expand Dohko's earlier life. *Next Dimension* depicts his adolescence during the 18th-century Holy War, showcasing training alongside Shion and Crateris Suikyo. Here, his impulsive nature surfaces during unauthorized missions, balanced by an emerging sense of justice. A significant temporal anomaly occurs when his future pupil Shiryu arrives from the 20th century, prompting Dohko to entrust him with Athena's protection despite paradoxes. *The Lost Canvas* portrays alternative events: Dohko's origins within the Chinese Taonia order, marked by a tiger tattoo symbolizing his destined path. As a Gold Saint in this timeline, he undertook missions to Italy, encountering the young Pegasus Tenma—whom he later instructed—and confronted Hades' forces directly. His narrative concludes with a sacrificial act against Hades, enabling his allies' retreat before he sustained a fatal wound. Across all narratives, Dohko remains distinguished by his dual identity: a guardian preserving ancient wisdom and a warrior whose tactical acumen repeatedly shapes humanity's defense. His legacy persists through successors like Shiryu, prophesied to inherit the Libra Gold Cloth, cementing Dohko's influence beyond his physical presence.
