☆ Tenya Iida

Tenya is a relatively tall and muscular young man with a wide frame. He has short dark blue hair, flattened neatly down and parted on the right side of his head, a small patch completely shaved near the base of his head, and rather square eyes which match the notably pointed shape of his jaw. He usually wears a serious expression, and his eyebrows seem permanently pointed inwards, quite thin and long, the far ends sharply hooked inwards, and he wears glasses with rectangular lenses. Because of his Quirk, he possesses calves that are incredibly thick, and shaped like automobile engines, with six silver exhaust pipes protruding from each leg in columns of three. He gains new mufflers after removing the old ones from his legs, with them being longer and shaped a bit differently.

His hero costume consists of a dark blue one-piece suit with a high collar, over which he wears various pieces of armor, all in a pale silver, including a chest plate, a metal collar around his neck and another around his upper arm, and metal vambraces that extend past his elbows pointed at the ends. He wears a helmet covering his entire face, its sharp bevor full of holes to allow him to speak and breathe easily, and its upper piece rounded over his head with two larger holes on either side, two curved horns just behind and a single spike sticking out of the back of his head.

On his feet, he wears silver knee-high boots with gold accessories, which are specialized for his Quirk, and around his torso, he has three thick metal pipes, attached with a blue band, although these only serve as decoration. His armor is very lightweight and does not protect him much; its main purpose is to cut down air resistance rather than to protect him.

Following the Hosu Incident, a scar remains across Tenya's left shoudler.

Hero Costume: Tenya's hero costume is an armored suit that supposedly decreases wind resistance but is actually mostly for decoration. Contrary to its appearance, his armor is lightweight.

Ingenium Boots (インゲニフット, Ingeni-Futto?): The boots contain cooling devices and other mechanisms that augment the performance of his engines. As a result, his running distance is greatly extended. Ingenium Helmet (インゲニメット, Ingeni-Metto?): The helmet reduces wind resistance. Ingenium Muffler (インゲニマフラー, Ingeni-Mafurā?): The muffler is for decoration.

エンジン, Enjin?): Tenya's Quirk gives him car-like engines in each of his calves, giving him incredible running speed and extreme kicking power. Tenya needs to fuel his engines by drinking orange juice.

Tenya's engines have multiple gears; it is currently unknown how many, but it has been implied that there are more than three. Much like a real engine, his Quirk requires that the exhaust pipes on the backs of his legs remain clear of obstructions to function correctly.

Tenya engaged in hardcore, long-distance running as part of his training to increase his leg strength and stamina to run faster for more extended periods. During the Quirk Apprehension Test, he ran fifty meters in 3.04 in third gear, meaning he ran at an average speed of 51.29 kilometers per hour (36.79 miles per hour), making his maximum speed exceedingly above this.

Sometime before the Joint Training Battle, his older brother Tensei told him about a secret family method regarding their Quirk, prompting Tenya to remove the mufflers from his legs to grow new ones to withstand his training. His Recipro now lasts for ten minutes, as opposed to ten seconds. However, Tenya becomes so fast that he cannot control himself, though he gradually gains better handling over his heightened speed.

Ultimate Moves Engine Boost (エンジンブースト, Enjinbūsuto?): This move allows Tenya to accelerate his Quirk. Recipro Burst (レシプロバースト, Reshipuro Bāsuto?): This move allows Tenya to forcibly accelerate his Quirk, giving Tenya greatly enhanced speed for ten seconds at the cost of disabling his engines for a short period of time afterward. Even Shoto could not fully evade Recipro Burst and admits that he expected no less of its incredible speed.[4] Recipro Extend (レシプロエクステンド, Reshipuro Ekusutendo?): After Tenya manages to cool down the negative effects of Recipro Burst, he regains even more acceleration than before.[5] Recipro Turbo (レシプロターボ, Reshipuro Tābo?): After removing his mufflers and allowing new ones to grow in their place

Tenya may look severe, unfriendly, and even intimidating at first glance, but in reality, he's straightforward, earnest, intelligent, sophisticated, disciplined, and noble, although a bit clueless about personal interactions due to his elite upbringing.Being part of the highly-esteemed Ida Family, Tenya is proud of his lineage and works hard to meet his expectations. Tenya greatly admires his older brother, Tensei (also known as the Turbo Hero: Ingenium) and aspires to become a similar hero. His relationship with his brother is so strong that after Stain severely injured Tensei, Tenya sought to avenge him by trying to hunt down and dispose of the Hero Killer himself. In doing so, he broke several rules of Hero work and laws, which otherwise would have been extremely uncharacteristic. Despite this, he realized the error of his actions and how his behavior was not that of a hero's. Following this incident, Tenya started over as a hero, and having inherited the alias of Ingenium, he now works hard to uphold his brother's Hero name and live up to the reputation of the Ida Family.
