Rikidō Satō, known as the hero Sugarman, trains in U.A. High School's Class 1-A. Born June 19 in Tottori Prefecture, he stands 185 cm tall with a muscular build, brown spiked hair, small square-shaped eyes, bushy eyebrows, full lips, and a notably large nose. His blood type is O. His initial hero costume featured a yellow full-body suit with eye, mouth, and hair openings, plus white gloves, boots, and a sugar-storing utility belt. His post-graduation costume removes the suit top, showcases a bulkier physique with a sleeker jawline and light stubble, and features jagged gloves. Satō possesses a kind, orderly personality and a strong passion for baking sweets, a skill honed to affordably sustain his Quirk. His classmates enthusiastically enjoy his weekly "Sugar Time" confections, though he underestimates his culinary skill. He joins Momo Yaoyorozu for daily tea sessions, pairing her tea with his desserts. Generally reserved, he shows camaraderie with peers like Denki Kaminari and Hanta Sero, and displays protective instincts, such as confronting Izuku Midoriya to advocate for class unity. His Quirk, Sugar Rush, requires consuming sugar: 10 grams quintuples his strength for three minutes, with each additional 10 grams extending the duration by another three minutes. Drawbacks include gradual cognitive decline during use, followed by drowsiness and physical exhaustion. He favors close-range melee combat, utilizing Ultimate Moves like **Sugar Rush** (a rapid barrage of punches), **Sugar Knuckle** (a single powerful straight punch), and **Beast Senior** (an uppercut technique). His base physical capabilities are athletic, featuring supersonic combat speed and peak human lifting strength. Activated Sugar Rush elevates his attack potency to building level, enabling feats like shattering Cementoss' constructs or Bakugō's Grenadier Bracers. His utility belt consistently carries sugar reserves for Quirk readiness. During U.A.'s entrance exam, Satō ranked 12th in Shōta Aizawa's Quirk assessment test. Key involvements include subduing Kurogiri with Hanta Sero during the U.S.J. Incident; placing 15th in the Sports Festival obstacle race but losing the cavalry battle; failing the Final Exams against Cementoss with Eijirō Kirishima due to stamina depletion; passing the Provisional License Exam's rescue exercises after reuniting via Yuga Aoyama's laser; freeing Katsuki Bakugō to secure victory in the Joint Training Battle; administering sedatives to Gigantomachia during the Paranormal Liberation War; and participating in Class 1-A's confrontation against Midoriya in the Dark Hero Arc. His internship under the Lion Hero: Shishido refined his attack flurries and situational awareness, emphasizing strength beyond Quirk reliance. Post-U.A., he works as a Sidekick for the Pro Hero Wash. Trivia includes his June 19 birthday, ranking #12 in midterm exams, and winning U.A.'s inaugural "Room King" contest due to popular appreciation for his baking. His surname "Satō" homophonically means "sugar," while "Rikidō" translates to "path to power." His initial character designs remained largely unchanged, reflecting an old-school superhero aesthetic.
