Tenya Ida serves as class president of U.A. High School’s Class 1-A, upholding the legacy of his renowned Ida Family, known for producing professional heroes. His older brother, Tensei Ida—formerly the hero Ingenium—motivates Tenya’s pursuit of heroism. After attending elite Soumei Junior High, he joins U.A., distinguished by his tall, athletic frame, rectangular glasses, and Engine Quirk, manifesting as engine-powered calves with exhaust pipes. His streamlined hero costume integrates lightweight armor for aerodynamics, later upgraded with a retractable helmet and enhanced exhaust systems engineered by Mei Hatsume. Tenya’s disciplined demeanor and strict adherence to protocol stem from his upbringing, reflected in formal gestures like raising his hand to speak. As a leader, he prioritizes order, directing classmates during crises such as the U.S.J. attack. Though initially rigid, he gradually embraces adaptability, participating in unsanctioned missions when necessary. His resolve is tested during the Hosu Incident, where vengeful fury drives him to battle the Hero Killer Stain after Tensei’s near-fatal injury. Allies Izuku Midoriya and Shoto Todoroki redirect his focus from revenge to rescue, leaving Tenya with a shoulder scar and a deepened dedication to heroic ideals. He eventually inherits the Ingenium mantle, vowing to honor his brother’s legacy. Academically proficient, Tenya ranks second in Class 1-A’s midterms and fourth in the Quirk Apprehension Test. His combat style harnesses explosive speed through techniques like Recipro Burst and Recipro Turbo, securing victories in the U.A. Sports Festival and earning 301 hero nominations. During the Paranormal Liberation War, he delays Near High-End Nomu and aids evacuations, later achieving Mach 3 speeds in the Final War to transport Shoto Todoroki against Dabi. Post-graduation, Tenya ascends to No. 13 Pro Hero, adopting a redesigned costume with compact briefcase storage and a sleeker, slicked-back hairstyle. Eight years post-Final War, he continues as Ingenium, emphasizing cooperative rescue operations. Evolving from a rule-centric student to a leader valuing unity over individual acclaim, he embodies his family’s ethos of selfless service.
