Tenya Ida (
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 to be permanently pointed inwards, quite thin and long in length, 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 three silver exhaust pipes protruding from each one.
His hero costume consists of a black one-piece suit with a high collar, over which he wears various pieces of armor, all in a pale silver in color, 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.
Tenya may look severe, unfriendly, and even intimidating at first glance, but he's actually a very straightforward, earnest, intelligent, sophisticated, disciplined, and noble person, although a bit clueless about personal interactions due to his elite upbringing. A testament to his generally hyperactive and intense behavior, Tenya often exhibits plenty of peculiar tics, such as moving his arms around in strange chopping patterns or sometimes twitching his own body uncontrollably, yet he rarely sheds his usual strict expression.
Tenya tends to take everything very seriously and is known for his habit of jumping to conclusions, then enthusiastically speaking or acting based on said conclusions. For example, after assuming that Izuku Midoriya had figured out the true nature of the U.A. Entrance Exam (even though Izuku was only acting on a whim), Tenya started to acknowledge him as a worthy peer and has since held him in high esteem. Furthermore, Tenya always attempts to immerse himself heavily into practical exercises, playing his part as a hero or villain in an overly theatrical manner, as an attempt to appear more authentic.
Tenya is extremely dedicated to his studies and is always eager to learn new things, regardless of whether they have anything to do with Heroics. As Class 1-A's representative, Tenya is obsessed with organization and discipline, expecting his classmates to follow suit, which more often than not annoys them due to his usually loud and overbearing nature. At the same time, Tenya takes personal responsibility for the safety and guidance of his classmates in times of crisis, considering it his duty as class representative to protect and keep them away from dangerous situations should they ever arise. Tenya knows how to quickly respond to situations of emergency, making sure to downplay panic and disorder among bystanders.
Tenya is very humble, willing to admit to his mistakes, apologize for rude behavior, and improve himself in areas he is lacking. This became clear when Tenya admitted that seeking vengeance against Stain was not the way a real hero should act, and shortly after the altercation with the Hero Killer, he decided to leave his damaged left hand unhealed, both as a reminder of his recklessness and as a motivation to pursue true heroism. Tenya values honor and fair play, becoming outraged if it turns out that he is being manipulated by more selfish personalities such as Mei Hatsume who used him during their battle in the U.A. Sports Festival to promote her inventions.
Being part of the highly-esteemed Ida Family, Tenya is proud of his lineage and works hard to meet the expectations placed upon him. Tenya greatly admires his older brother, Tensei Ida (also known as the Turbo Hero: Ingenium) and aspires to become a hero similar to him. His relationship with his brother is so strong that after Tensei was severely injured by Stain, Tenya sought to avenge him by trying to hunt down and dispose of Stain himself. In doing so, he broke several rules of Hero work in the process, which otherwise would have been extremely uncharacteristic of him. Having inherited the alias of Ingenium, Tenya now works hard to be able to uphold his brother's Hero name and live up to the reputation of the Ida Family.
Overall Abilities: Tenya has repeatedly shown that he is a highly formidable combatant. His skills earned him 4th place in the Quirk Apprehension Test; 6th place in the U.A. Entrance Exam, having the second-highest amount of villain points; and 4th place at the U.A. Sports Festival, although he qualified for 3rd place if he had stayed for the closing ceremony. Thanks to his Quirk, Tenya has been revered as one of the fastest students in Class 1-A, and he uses his increased speed to supplement his fighting style which involves powerful, high-speed kicks that can even crush metal. Using his incredible speed and quick reflexes, Tenya was able to defeat Ibara Shiozaki, one of the most formidable students in Class 1-B, and nearly defeat Shoto Todoroki, one of the strongest students in Class 1-A, but the latter blindsided Tenya by freezing his mufflers before encasing Tenya in ice. Shoto and Izuku, two of the most powerful students in their class, have both commented on Tenya's superior speed. Still, while Izuku has trained himself to keep up with Tenya, Shoto is unable to keep up with all of Tenya's high-speed movements.
When facing the Hero Killer: Stain—a powerful A-Rank villain who bested many pro heroes, including Tenya's brother, Tensei—Tenya himself was fueled with an unadulterated sense of vengeance for his brother, which ultimately led to him almost being killed by the Hero Killer after Tenya had voluntarily hunted the assassin down. But after Izuku and Shoto arrived to help, Tenya discarded his desire for vengeance and was able to hold his own against Stain while working alongside his two classmates. During the said bout, Tenya was able to tap into a new Super Move, "Recipro Extend", with Shoto's help in order to help successfully immobilize Stain. Following his run-in with the Hero Killer, Tenya has been recognized as one of stronger students of Class 1-A, as noted by Pixie-Bob. During the Joint Training Battle, Tenya, using the advice given to him by his older brother, was able to increase his speed to the point where he is much faster than Gran Torino, who is revered as one of fastest heroes in the world. With his new speed combined with his fighting style, Tenya was able to overwhelm Juzo Honenuki, a recommended student, and force him to retreat.
Keen Intellect: Tenya was ranked 2nd place in the mid-terms for Class 1-A, proving his tremendous academic prowess. He was able to discern that there were parameters of the U.A. Entrance Exam that he was unaware of. Tenya also has strategic and tactical abilities. When facing the Hero Killer: Stain, Tenya recalled how Shoto had frozen his mufflers during their battle at the U.A. Sports Festival and used it as a battle tactic to increase his speed even further in order to blindside Stain. When he was paired with Mashirao Ojiro to battle Power Loader in the Final Exams, Tenya came up with a strategy that involved carrying Mashirao on his back and using "Recipro Burst" in order to swiftly evade the traps Power Loader had set. When it seemed that the Pro Hero was about to defeat them, Tenya quickly thought of another plan, in which Mashirao wrapped his tail around Tenya’s leg, and Tenya himself used "Recipro Extend" to fling Mashirao to the escape gate, while the latter parried Power Loader's attack, quickly securing victory for the young heroes.
- Leadership Skills: Tenya is a strong leader, as shown when he was able to calm his panicked peers during an evacuation that was turning into a stampede. Tenya became class president of Class 1-A after Izuku resigned and gave the position to him, believing him to be better suited for the job.
Engine (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 in order to function properly.
As part of his training, Tenya engaged in hardcore, long-distance running to increase his leg strength and stamina so that he can run faster for longer periods of time. During the Quirk Apprehension Test, he ran 50 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 greatly in excess of this.
Sometime before the Joint Training Arc his older brother Tensei told him about a secret family method regarding their Quirk. This prompted Tenya to remove the mufflers from his legs in order to grow new ones to withstand his training. This exhibits his capacity for pain and perseverance. His Recipro now lasts for ten minutes, as opposed to ten seconds. However, he becomes so fast that he cannot control himself.
- Engine Boost (エンジンブースト Enjinbūsuto?): This move allows Tenya to accelerate his Quirk, This is the only move that isn't a Recipro.
- 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.
- 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.
- 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 is able to accelerate his Quirk and greatly enhance his speed for ten minutes. The speed this Super Move grants is faster than Recipro Burst and Recipro Extend, rivaling even Jet.
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.
Battles & Events
