Son Goku emerged from a primordial stone on Mount Gogyou, defying categorization as human, youkai, or divine. His existence intertwines with celestial upheaval, having been entrusted to Konzen Douji—a celestial bureaucrat—and forming bonds with generals Tenpou and Kenren during his heavenly tenure. A catastrophic eruption of power occurred when his restraining diadem was removed, unleashing cataclysmic devastation across Heaven and claiming countless celestial lives. This act condemned him to 500 years of stone imprisonment on Mount Gogyou until Genjo Sanzo, a renegade priest, freed him for a quest to thwart demon king Gyumaoh’s resurgence. Physically resembling a sun-kissed adolescent with golden eyes, Goku’s diadem serves as both crown and shackle. Its removal awakens Seiten Taisei, the “Great Sage Equaling Heaven,” manifesting elongated ears, clawed hands, and the kanji for “completion” etched across his torso. This primal form amplifies his strength, regeneration, and elemental mastery but erodes empathy, replacing playful mischief with merciless aggression. Emotional fractures repeatedly trigger his metamorphosis: Sanzo’s near-death at Rikudo’s hands, Ukoku Sanzo’s lethal strike, and other traumas force allies to intervene, restoring his humanity through diadem and camaraderie. His bond with Sanzo evolves from childlike dependence to tempered mutual trust, the priest’s stern exterior masking paternal vigilance. Goku balances voracious appetites and mischievous humor with fierce loyalty, shielding the vulnerable despite occasional pranks spiraling into chaos. In battle, he commands the shape-shifting Nyoi-Bo staff with precision, contrasting his godlike Seiten Taisei persona—a storm-wielding force of nature unrestrained by morality. His arc interrogates duality: the diadem embodies the tension between annihilation and connection, while confrontations with figures like Kogaiji and celestial remnants challenge his search for identity. Redemption emerges not through solitary struggle but through alliances anchoring him to humanity, framing his narrative as a collision of cosmic power and fragile, hard-won belonging.
