Rikidō Satō features as a supporting character in *My Hero Academia the Movie -Heroes: Rising-*, retaining his established role and abilities from the main series. As part of U.A. High School's Class 1-A, he joins the class assignment to Nabu Island for community safety operations and resident protection against villains. When the villain Nine and his associates invade the island, Satō works alongside classmates to evacuate civilians and combat threats, utilizing his typical close-range combat style centered on enhanced physical strength. His capabilities revolve around the Quirk **Sugar Rush**: consuming 10 grams of sugar temporarily quintuples his strength for three minutes, followed by cognitive impairment and fatigue. Each additional 10 grams extends the duration by three minutes. During Nabu Island's conflict, he likely employs his signature techniques—**Sugar Rush**, a rapid barrage of empowered punches, and **Sugar Knuckle**, a single concentrated strike. His utility belt, storing sugar for Quirk activation, complements his standard hero costume—a yellow full-body suit with eye, mouth, and hair openings, white gloves, and boots. Satō contributes to Class 1-A's unified defense against Nine's faction, safeguarding the island's residents. His personality traits, such as baking sweets for peers and cooperative demeanor, remain consistent throughout the film.
