Quirk: Engine Tensei Iida also known as Turbo Hero Ingenium 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 with square features and short black spiked hair. A differing feature is that he possesses arrowshaped eyebrows and has a slightly longer face. Similar to his brother he has engine exhausts protruding from his body but out of the ends of his elbows instead of his calves. Also in Illegals: Tensei meets with Koichi during an early morning run. Tensei is impressed with Koichis Quirk and offers him a place in his agency even expressing a desire for a sidekick with a fast mobility quirk. Later when Tensei discovers Koichi has been working as a vigilante hero he withdraws his offer to Koichi but only because he believes him to be already in the right place.
