Juzo Honenuki, operating as the Pro Hero Mudman, secured his place in U.A. High School's Class 1-B through recommendation, one of only four students in his year granted this honor alongside peers like Momo Yaoyorozu and Shoto Todoroki. His pre-U.A. background remains largely undefined, though his recommended status signifies prior high achievement. Eight years after the Final War, he graduates from U.A. and attains the rank of No. 14 Pro Hero. Physically, Juzo possesses pale skin, angular black eyes, mid-length beige spiked hair, a flat nose, and small eyebrows. His most distinctive trait is his perpetually exposed teeth, sitting outside his skin due to a lack of discernible lips, creating a skull-like appearance unrelated to his Quirk. He stands 174 cm (5'8½"). His hero costume comprises a dark bodysuit layered with armor: a rounded helmet featuring a retractable snorkel, a three-piece chest plate secured by shoulder straps, orange and black vambraces, thigh and calf plates, elevated green and orange boots, white gloves, and kneepads. This costume evolves over time into a more mechanical, streamlined design. Casually, he wears standard U.A. uniform or sometimes a green high-collared coat to conceal his mouth. Juzo's personality blends calmness with fierce determination and a strong aversion to losing. He exhibits "flexible thinking," enabling rapid tactical adaptation in combat. Supportive of classmates, he values friendships with Sen Kaibara and Shihai Kuroiro. While generally understanding, he displays occasional stubbornness under high pressure. He is bilingual in Japanese and English, with conversational French. He enjoys sweets, soft blankets, and binge-watching shows, disliking rudeness, sour foods, and dental visits. His Quirk, Softening, liquefies non-living materials on touch, reverting them to solidity with another contact. This turns terrain like concrete or earth into quicksand, hindering enemies or creating ambushes. He "swims" through softened substances for stealth or rapid movement. The Quirk's range extends tens of meters but requires direct touch. Tactically, Juzo employs it to soften Shoto Todoroki's ice attacks during the U.A. Sports Festival, immobilizing opponents, or destabilizing structures like water towers in the Joint Training Battle. Analyses note his skill in exploiting environmental hazards and enemy predictability. Juzo's combat prowess is reflected in U.A. stats: Speed (5/6), Technique (5/6), Wits (5/6), and Flexible Thinking (5/6). He demonstrates exceptional reflexes, countering Shoto's "Heaven-Piercing Ice Wall" before it fully encased his team. As a recommended student, his analytical skills identify team weaknesses and predict adversary strategies. During the Joint Training Battle against Class 1-A, he anticipates Shoto's opening ice assault, softening it to trap Tenya Iida and others. He pragmatically recognizes when opponents gain advantages, retreating upon Tenya activating "Recipro Turbo" to avoid unwinnable fights. Key appearances include the U.A. Sports Festival, where his Quirk debuts hindering Izuku Midoriya's team; the Forest Training Camp, where Mustard's gas incapacitates him; and the Joint Training Arc, showcasing his tactical leadership. His development culminates in professional heroism, though specific post-U.A. events beyond his No. 14 ranking remain undetailed. His design, occasionally compared to horror-inspired characters like Ectoplasm or Gang Orca, contributes to an intimidating presence despite his heroic alignment.
