People who find a lost child and then take him to a lost-child center... I've always thought those sorts of people were the coolest.
Tensei Iida to Tenya Iida in "Re-Ingenium"

Tensei Iida ( (いい) () (てん) (せい) Īda Tensei?), also known as Turbo Hero: Ingenium (ターボヒーロー・インゲニウム Tābo Hīrō Ingeniumu?), is the older brother of Tenya Iida and a former Pro Hero.


Outside of his hero armor Tensei looks much like his younger brother, Tenya Iida, with square features and short black spiked hair. A differing feature is that he possesses arrow-shaped eyebrows and has a slightly longer face. Unlike Tenya, he does not wear glasses.

Similar to his brother, he has engine exhausts protruding from his body as a result of his Quirk, but his come out of the ends of his elbows instead of his calves.


Compared to his younger brother, Tensei is far more laid back with an easy-going attitude. When he took up the hero mantle of his family, his image for himself was that he wanted to 'be cool' and be the type of hero that helps others when they are in need. He was joyful that his younger brother admired his work as a hero as a result.

He also believes that being able to rescue people quickly is what makes a great hero and that people want to be rescued in a hurry and value being saved quickly. He also values teamwork, believing that having a large group where everyone serves a specific purpose is the easiest way to rescue people quickly.

Although working as a Hero, he is lenient on laws. Unlike his younger brother, he doesn't scold others for using their quirk in public but instead helps them develop them. He also suggested the notion of taking on a sidekick who didn't have a Provisional Hero License, which is against the law, stating that he could 'earn his qualification little by little'.



Tensei's Quirk

Tensei's proficient use of his Engine Quirk.

Engine: His Quirk manifests in the form of engines in his elbows, allowing him to create blasts and shoot himself forward at turbo speed. He hovers a foot or so off the ground and relies on the propulsion from his arms to move at super speed, and has been seen using his Quirk to move faster than cars in a chase sequence. Unlike his brother Tenya, his Quirk does not seem to have gears and can hit max speeds in an instant; however, he finds it difficult to brake and turn while moving at top speeds and compensates by installing airbags in his Hero Costume.[1]

Super Moves

  • Recipro Burst (レシプロバースト Reshipuro Bāsuto?): By over-torquing his engines, Tensei is able to produce an explosive burst of speed. This also causes his engines to overheat.[2]
  • Rocket Charge (ロケットチャージ Roketto Chāji?): Tensei's hero costume increases and focuses his engines' output, affording him greater acceleration and launching him into the air, like a rocket. This causes his engines to stall.[2]
