Tenya Iida, the disciplined class representative of U.A. High’s Class 1-A, wields the Engine Quirk—automotive engines embedded in his calves that propel him at superhuman speeds. These engines demand orange juice as fuel, falter under carbonated beverages or ice, and risk overheating without cooldowns. His advanced techniques push these limits: Recipro Burst unleashes explosive velocity before temporary shutdown, while Recipro Extend and Recipro Turbo, honed through rigorous training and muffler repairs, enhance acceleration and sustained speed. Heir to the hero-legacy Iida family, Tenya once emulated his brother Tensei, the retired Ingenium. When Stain crippled Tensei, vengeance consumed Tenya, driving him to forsake his duties and face the Hero Killer alone—a reckless choice that nearly shattered his ideals. Surviving the clash, he emerged resolved to honor heroism through unity, preserving his battered armor as a testament to this hard-won wisdom. Rule-bound and initially inflexible, Tenya prioritized order over camaraderie, chastising peers like Izuku Midoriya and overlooking Ochaco Uraraka’s needs. Yet humility gradually tempered his rigidity. Embracing collaboration, he reshaped his leadership from enforcing discipline to nurturing trust, acknowledging past missteps as he championed his classmates’ collective strength. His sleek armored costume minimizes wind resistance, while boot-mounted cooling systems optimize engine performance. Though combat-focused, Tenya’s tactical mind shines in moments like countering Ochaco’s Quirk by clearing debris mid-battle. Academically exceptional, his disciplined study habits mirror his relentless dedication. Tenya’s evolution bridges family tradition and self-discovery. Once fixated on upholding the Iida name, he now defines heroism through selfless service, forged in crucibles of teamwork and villain confrontations. His journey—from rigid idealist to adaptive leader—underscores the resilience found in humility, allyship, and the courage to grow beyond legacy.
