Suiryu, heir to the prestigious Void Fist martial arts lineage, trained rigorously under his grandfather Suicho alongside his sister Suiko. A natural prodigy, his early dominance in combat bred complacency as victories came too easily, prompting a three-year hiatus from consecutive Super Fight tournament wins. Rumors of Garou’s disguised participation as Wolfman reignited his hunger for challenge, drawing him back to the 22nd Super Fight. There, he effortlessly dismantled A-Class heroes Max and Sneck, masking perceptiveness beneath a veneer of casual mockery—detecting Bakuzan’s lethal intent and Saitama’s concealed power. His philosophy rejected heroism as futile, prioritizing personal freedom and combat-driven exhilaration over altruism. Clashing with Saitama—disguised as Charanko—upended his worldview. Unleashing techniques like Void Sky Dragon Fist, Suiryu initially dominated until Saitama’s impervious resilience exposed his limitations. A single restrained punch from Saitama fractured his arrogance, replacing confidence with visceral fear and a resolve to avoid further recklessness. The Monster Association’s invasion forced Suiryu into survival mode. Refusing Gouketsu’s offer to become a monster executive, he battled transformed foes like Choze, countering energy attacks with Void Fist precision. Gouketsu’s overwhelming assault and Bakuzan’s betrayal left him broken, pleading for a hero’s aid as death loomed. Rescued by Saitama and witnessing heroes’ self-sacrifice, Suiryu’s disdain for heroism eroded. Post-recovery, he sought mentorship under Saitama and joined the Neo Heroes, balancing pragmatism with a fledgling sense of duty. Physically peerless, Suiryu’s superhuman attributes allowed arena-splitting strikes and survival against Dragon-level threats. Void Fist techniques blended fluidity with destructive force, epitomized by Void Shaking Tiger Fist and Void Phoenix Ascension Fist, while heightened senses pinpointed opponents’ weaknesses. Later Neo Heroes involvement saw him adopt advanced combat suits to amplify his capabilities, though specifics remain undisclosed. His arc traces a path from arrogant isolation to reluctant leadership, intertwining martial mastery with incremental accountability.
