Tenya Ida

Tenya Iida (飯田天哉) is one of the protagonists of Boku no Hero Academia and the Class President of Class 1-A.

Appearance
Tenya has a tall and muscular physique. He has black hair and wears square shaped glasses.

Tenya's hero costume is a black one piece suit with a high collar. He also wears a helmet that covers his entire head, a metal collar around his neck, armor on his chest, mufflers that start on his stomach then extend to his upper back, a metal piece below the mufflers, metal armbands that extend past his elbows, and metal boots that extend up past his knees and some that extend up that side of his legs.

Personality
He may look severe, but he's actually a very straight forward, earnest, diligent and serious person, who takes everything (even the most insignificant of things) seriously. Because of this he has a tendency to make quick assumptions on everything from his own performance to the actions of his classmates, such as praising Izuku's apparent insight of the entry exam's 'true nature', despite the contrary.

He is also a very humble person, who will admit his mistakes and try to improve himself; Tenya admitted that he wasn't a true Hero for seeking vengeance against Stain and decided to move forward so that people such as Izuku and Shouto don't surpass him as a Hero; Tenya decided to not have his left hand healed in order to remind him of his mistake and to motivate him to become a Hero anew. Tenya likes fair play, as he agreed to use the support gadgets Mei gave them for their match in the Sports Festival so that they could fight on equal terms. He also dislikes being manipulated, angered that Mei used him just so that she could advertise her gadgets during their match in the Sports Festival.

Tenya admires his older brother, Tensei (also known as Turbo Hero Ingenium) and wants to become like him. Tenya's bond with Tensei is so strong that after Tensei was severely injured, Tenya became vengeful, wanting to avenge his older brother by disposing of Stain himself.

Quirk and Abilities
Engine (エンジン Enjin): Tenya's Quirk allows him to use his legs as engines, giving him super speed. It is also revealed that Tenya has different types of gears with his engine. So far this allows him to switch from First, Second or Third Gear to make adjustments to his speed depending on the situation. Much like a real engine the Quirk requires that the exhaust pipes on the back of his legs remain clear of obstructions in order to function properly, as well as having a radiator in order to cool down after high-use.
 * 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 10 seconds but at the cost of disabling his engines for a short period of time. Even Shouto Todoroki could not fully evade Recipro Burst and admits that he expected no less of its incredible speed.
 * 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.

Leadership Skills: Tenya has shown to be a great leader, as he was able to stop the chaotic evacuation when Yuuei was infiltrated. Tenya became President of Class 1-A after Izuku resigned and gave the position to him, thinking that he was better suited to the job due to his exceptional leadership.

Equipment
Tenya's hero costume is an armor that decreases wind resistance; however, the armor is just for decoration. Contrary to the appearance, his armor is lightweight.
 * Ingenium Boots- The boots has cooling devices and supporting devices for the engines that are located at the feet. Moreover, it also can greatly extend traveling distance. The exhaust pipes surround the ankle.
 * Ingenium Helmet- The helmet is capable of reducing wind resistance.
 * Ingenium Neck Piece- The neck piece is for decoration.
