Hyoga, the Bronze Saint of Cygnus, hails from Siberia, training under the Crystal Saint after his mother perished in a shipwreck. Her body lies beneath the frozen sea, driving his quest to become a Saint and gain the power to visit her underwater grave. This emotional bond clashes with the Saints' doctrine of detachment, anchoring his core conflict. During the Hades Chapter - Sanctuary, Hyoga ignores Athena's command for non-interference, infiltrating Sanctuary to defend her. He battles resurrected Gold Saints, including his former mentor Aquarius Camus, now aligned with Hades. This confrontation compels Hyoga to balance lingering reverence for Camus against combat exigencies, intensifying his struggle between duty and sentiment. Throughout the Sanctuary assault, Hyoga fights Hades' Specters and rogue Saints. His skills prove vital in aiding allies, particularly Andromeda Shun, whom he safeguards out of indebtedness after Shun revived him in a prior Sanctuary conflict. Hyoga wields cryokinesis, channeling Cosmo energy to control ice and cold. His signature moves include Diamond Dust—a freezing strike, Kholodnyi Smerch—an icy tornado uppercut, and Aurora Execution—an absolute zero technique mastered under Camus. Amid the Hades war, Athena's blood anoints his Cygnus Cloth, evolving it into the Final Bronze Cloth to withstand divine foes. His growth pivots on transmuting vulnerability into fortitude. Once perceived as distant, his loyalty to his mother and comrades evolves from a liability into power, a duality tested when adversaries exploit these ties during the Hades Sanctuary arc.
