Tensei Ida

Tensei Iida (飯田天睛), also known as Turbo Hero Ingenium (ターボヒーロー・インゲニウム), is the older brother of Tenya Iida and a Pro Hero.

Ultimate Space & Jams Arc
Tensei is briefly mentioned by Tenya, when talking about his family.

Sports Festival Arc
Tensei is heavily injured by Stain and left for dead. However, the police find him and he is taken to the Hosu General Hospital for emergency treatment. Tensei undergoes an operation that saves his life. Afterwards, Tenya immediately barges into the room to see his older brother. Tensei, despite being weak, speaks to his younger brother, apologizing to Tenya for being unable to be the role model that Tenya sees him as.

Tensei admits to Tenya that he can no longer feel any movement in his legs and says that this is probably the end for Turbo Hero Ingenium. Tenya refuses to believe this, unable to stand the idea that his brother will no longer be a Hero. Tensei tells Tenya he cannot stand the idea either and asks him to carry on the torch; use Ingenium as his Hero name.

Powers and Abilities
Although he has not been seen using any specific abilities to date, it is assumed that, given his Pro Hero name "Turbo Hero Ingenium", that he possesses a Quirk similar to that of his younger brother, Tenya Iida. Therefore, he, too, is likely to be centered around high-speed combat powered by leg speed boosters.
