Suiryū reigns as a five-time Super Fight tournament champion, achieving four consecutive victories that cemented his dominance through mastery of the Void Fist martial art. He possesses a tall, lean muscular frame, tan skin, blue eyes, and long black hair secured in a low ponytail. His signature attire is a navy blue Chinese-style martial arts uniform with white trim and star-shaped buttons, accented by metal armbands; later, he adopts the Neo Heroes' specialized battle suit, which enhances his physical capabilities via mobility analysis and incorporates life support. Initially projecting a relaxed, carefree persona, Suiryū openly prioritizes personal enjoyment, especially socializing with women, over training. He possesses keen perceptiveness for opponents' bloodlust and adheres to a philosophy of natural selection, believing inherent strength dictates survival. Bored by unchallenging fights, he often imposes handicaps like fighting solely with his legs. Against formidable opponents, however, this facade drops, revealing ruthless arrogance and a win-at-all-costs mentality, including rule-breaking. He harbors deep skepticism toward heroes, viewing them as self-important and ineffective at permanent solutions, reinforcing his thrill-seeking lifestyle detached from heroism. Suiryū exhibits superhuman physical attributes: strength allowing effortless single-kick defeats of A-Class heroes, splitting arena structures with hand chops or stomps, redirecting energy attacks, and shattering metal restraints. His speed and reflexes enable movements invisible to ordinary humans, rapid aerial repositioning, and evasion of skilled strikes. His durability withstands concrete-shattering impacts and halts piercing attempts via muscle hardening. His endurance permits consciousness through prolonged beatings from Dragon-level threats while injured. His combat expertise lies in the high-damage Void Fist style, utilizing fluid combative sequences. Key techniques include: - Void Sky Dragon Fist: Generates tornado-like momentum through rapid aerial punches. - Void Shaking Tiger Fist: Channels ground-stabilized power for amplified strikes. - Void Phoenix Ascension Fist: A twisting punch capable of pulverizing heavy armor. He adapts tactics mid-battle, switching between hand and leg techniques. A pivotal shift occurs during the 22nd Super Fight tournament against Gouketsu, a Dragon-level monster and former champion. Offered power via monster transformation, Suiryū refuses, viewing monsters as abominations. His defeat by Gouketsu shatters his arrogance, leading to desperate pleas for help. Tortured later by another Dragon-level threat, Bakuzan, Suiryū displays residual pride by breaking Bakuzan's toe rather than submitting. Saitama's intervention to defeat both monsters prompts profound gratitude; Suiryū requests discipleship under Saitama and reevaluates heroism. This experience catalyzes Suiryū's transition into heroic work. He expresses newfound respect for heroes like Sneck and Max after being saved by them, acknowledging his previous disdain as misguided. Committing fully, he joins the Neo Heroes, attaining a leadership position as a Neo Leader. Utilizing their battle suit, which augments his abilities through synthetic muscle response and nervous system analysis, he dedicates himself to combating monsters and protecting civilians, marking a definitive departure from his earlier self-centered philosophy.
