Movie
Description
Tenya Ida, operating under the hero name Ingenium, hails from the distinguished Ida family lineage renowned for producing generations of professional heroes. His older brother, Tensei Ida, formerly bore the Ingenium mantle and served as Tenya's fundamental inspiration to embrace heroism, profoundly shaping his disciplined methodology and dedication to the profession. Prior to U.A. High School, he was educated at the elite Soumei Junior High School.

He possesses a tall, muscular physique with a wide frame, standing 179 cm (5'10½") tall. His appearance features short, neatly parted dark blue hair, square-shaped eyes, and a pointed jawline, typically accented by rectangular-lens glasses. His defining trait is the Engine Quirk, manifesting as automobile-like engines embedded in his calves, complete with exhaust pipes. This grants superhuman speed, though optimal function requires hydration like orange juice; the engines can stall if obstructed or if he ingests carbonated drinks. His hero costume incorporates lightweight armor for reduced air resistance and a full-face helmet with breathing holes. A scar remains on his left shoulder from Stain's attack during the Hosu Incident. Post-graduation, his appearance updates include slicked-back hair and a remodeled Ingenium costume stored in a briefcase.

Tenya's personality blends intense seriousness with earnestness and nobility. As Class 1-A's representative, he emphasizes discipline, organization, and strict adherence to rules, occasionally misjudging social cues due to his elite background. Hyperactive mannerisms, such as chopping arm movements, are characteristic. Core values of humility, honor, and protecting others drive him, exemplified during the U.S.J. incident when he prioritized evacuating to summon reinforcements for civilian safety. However, his rigid principles faltered temporarily when vengeance against the Hero Killer Stain for crippling Tensei consumed him—a choice he deeply regretted, leaving his injured hand unhealed as a permanent reminder. This crucible solidified his commitment to true heroism: selflessly aiding others without personal vendettas.

His combat prowess centers on high-speed movement and powerful kicks. Starting at 50 meters in 3.04 seconds, his velocity escalates dramatically through training, eventually achieving Mach 3 during the Final War to transport Shoto Todoroki across Japan in minutes. Key techniques include **Recipro Burst** (a short-term speed boost causing temporary engine stall), **Recipro Extend** (developed against Stain to extend mobility duration), and **Recipro Turbo** (an advanced, sustained high-speed mode surpassing professionals like Gran Torino). Academically, he ranks second in Class 1-A, excelling in strategic planning and crisis management. His combat proficiency places him among U.A.'s strongest, evidenced by holding his own against Shoto during the U.A. Sports Festival and assisting in battles against Near High-End Nomus.

Key story arc involvements include:
- **Entrance Exam**: Achieving sixth place through villain points, later acknowledging Izuku Midoriya's heroism in saving Ochaco Uraraka.
- **U.S.J. Invasion**: Escaping as class president to alert U.A. during the villain attack, enabling reinforcements.
- **Sports Festival**: Reaching the tournament's final four, showcasing his speed against formidable opponents.
- **Hero Internships**: His ill-advised pursuit of Stain led to near-fatal consequences until Midoriya and Todoroki intervened, triggering his moral awakening.
- **Final War**: Supporting Shoto against Dabi and aiding civilian evacuations, demonstrating his growth into a reliable hero.
In the film *My Hero Academia: You're Next*, Tenya operates within Shoto Todoroki's team (Team 3) to apprehend escaped villains. When Dark Might transforms a city into a fortress, trapping Tenya and classmates inside, he participates in countering the villain's forces and protecting civilians.

Eight years post-Final War, Tenya graduates as the No. 13 Pro Hero, assumes leadership of his brother's agency, Team Idaten, and carries the Ingenium hero name, honoring his family's legacy and embodying heroic ideals.
