Mirio Togata

Mirio Togata (通形ミリオ) is a third-year student at U.A. High School and is part of The Big 3. Before Izuku Midoriya, Mirio was the top candidate for All Might's successor and inheritor of One For All.

Appearance
Mirio is a muscular young man with scars on his arms. His face is drawn in a simplistic, cartoony way and his blond hair is arranged in a cowlick.

His Hero costume consists of a large mask which covers the space around his eyes and ears, a plated shirt with the number one million (1000000) across his chest, with black pants and boots. He also sports a floor length dark cape attached from the chest which also features a hood. Additionally, Mirio's hero costume (except for his mask) is made of a special fiber that is derived from hair, which allows the costume to become intangible alongside him.

In his youth, Mirio kept his hair in a short ponytail.

Personality
Mirio is goofy and energetic, with some peculiar habits. He is almost always smiling. Though optimistic, he does not let his ideals blind him, and is always looking for ways to improve his skills. He is very devoted to becoming a hero and is the top candidate for No. 1 Hero after he graduates, even surpassing many of the pros. Though he does not make the best grades in school, he is extremely dedicated and worked many hours to perfect the use of his Quirk for combat, and thus is ranked among the top 3 students at U.A.

As an intern, Mirio has developed a good understanding of the protocols and actions that a Hero must be able to do in various situations. He is able to separate himself from his emotions when order to in order to see the bigger picture. He understands when he had to go against what he feels is right in order to act for the greater good.

He is experienced in dealing with dangerous people, and does not scare easily, as shown when he was able to cheerfully speak to Overhaul, despite knowing exactly who he was, maintaining a cover of ignorance. He is able to remain calm when he has to, even casually informing Izuku to pull his mask on to conceal his identity. In spite of all of this, he is not totally able to disconnect himself from the realities of being a Hero. When it was revealed that Eri was being used as part of Overhaul's plans, he was visibly mortified at the fact that he and Izuku had been so close to rescuing her from such a fate. He then became extremely determined to rescue her.

Since the full use his quirk often leaves him nude, he has gotten somewhat used to it and isn't afraid to fight without clothes, though he will apologize, especially to girls, for the rudeness.

History
During third grade, a new transfer student was not able to give a proper self-introduction, and because of his social awkwardness, he was not able to make any friends. Mirio approached Tamaki Amajiki after realizing that Tamaki was trying to say that he likes Heroes; it was this recognition that began the friendship between Tamaki and Mirio. In middle school during a Quirk Education class, Tamaki tried manifesting something but only managed to manifest a tiny plant on his hand due to his nervousness. Meanwhile, Mirio tried phasing through a wall but only managed to phase his hands through it. Some of Mirio's classmates laughed at Mirio's struggles, but Mirio was not disheartened at all and resolved to pull off his phasing properly next time. While walking home, Tamaki praised Mirio's optimism while lamenting on his own lack of self-esteem. Mirio cheered up Tamaki and said that he will shine brightly like the sun and the reason he can give it his all is due to Tamaki being there for him. Although he was nervous, Mirio praised Tamaki's resolve never to give up which inspired him never to give up either. Despite Tamaki thinking himself as a boring person with low self-esteem, Mirio always thought of Tamaki as a talented person who is cool and super fun and sunny to be around with.

After middle school, Mirio and Tamaki entered U.A. According to Nejire Hado, Mirio once struggled a lot at U.A. High School (even showcasing poor results in an edition of the Sports Festival); however, he would turn around his situation by devoting himself as an intern under the hero Sir Nighteye and having his abilities cultivated during his internship, eventually becoming a major contender for the number one rank, above several pro heroes.

Internship Arc
Mirio appears with his fellow Big 3 members, and then proceeded to fight Class 1-A, defeating them all with a punch to the gut.

Quirk and Abilities
Permeation: Mirio's Quirk allows him to become intangible, letting him travel through solid walls and the ground, while letting enemy attacks slip through him. However, when he becomes intangible his clothes slips through him, leaving him nude. By activating his Quirk, he can slip through the floor into the ground, then reposition himself and deactivate to cause himself to shoot back out of the ground in a different spot. However while fully intangible, he can no longer see, hear, or breathe, and can only experience a falling sensation.
 * Blinder Touch: Eyeball Crush: A feint, Mirio pretends to poke an opponent in the eye while his arm is intangible, distracting them long enough to deliver an actual blow to their stomach.
 * Killing Move: Phantom Menace: A near instantaneous combo, Mirio consecutively launches himself in and out of his target's surroundings at high speeds with all of his brute force, striking from all directions.

Overall Abilities: Mirio is extremely powerful, showcasing incredible mastery over his Quirk, such that the students of Class-A thought him to be invincible. He is considered the top contender for the rank of number one hero, previously held by All Might and currently occupied by Endeavor. He was able to beat half of Class 1-A in less than six seconds.

Enhanced Strength: Mirio seems to possess a good deal of physical strength, enough to knock out a person and crush floors easily. This appears to come from his well-trained muscular body.

Enhanced Speed: Mirio is also incredibly fast, taking out Class-A very quickly and with absolute ease. This, combined with his strength and the rapid relocation aspect of his Quirk makes him incredibly formidable in combat.

Equipment
Specialized Costume: Since Mirio's Quirk usually lets him phase out of his clothes and leave him nude, he has a Costume that is made of a special fiber that is produced from his hair. That way his clothes will react when his Quirk activates and also become intangible.

Tamaki Amajiki
Mirio, Tamaki, and Nejire have known one another over the three years of their studies at U.A. During their years of study, Tamaki and Nejire have seen the endeavors Mirio had to go through and understood what he went through to become stronger and the technique Mirio created in the process.

Tamaki commented how Mirio was always strong since he was a child. Tamaki and Mirio have known one another in the past and the friendship between the two can also be deemed as a close one. The two refer to one another by their first names and were worried for one another when they respectively gone through dangerous or emotional situations.

Tamaki and Mirio hold a deep level of respect for one another. Tamaki idolizes Mirio's outgoing personality and tenacity to keep himself motivated and keep a level head, something Tamaki does not possess. Mirio once stated to Tamaki that he was able to give it his all because of Tamaki.

Nejire Hado
Like with Tamaki, Nejire and Mirio have spent three years together studying at U.A. becoming good friends with one another. During their years of study, she and Tamaki have seen the endeavors Mirio had to go through and understood what he went through to become stronger.

She and Mirio have similar energetic personalities which conflicts with Nejire's talkative attitude, much to her chagrin. However, this similar personality also make it easier for both of them to talk with one another, unlike Tamaki's quiet nature.

Izuku Midoriya
Prior to The Big 3's introduction, Mirio went out of his way to talk with Izuku. He is rather friendly to Izuku, who at first found Mirio to be strange. After witnessing Mirio's power and technique, Izuku grew to admire Mirio, even thinking that he already seems to be like a pro hero in the way he talks.

Mirio seems to hold him in high regard, despite only having just met and Izuku being a first-year. When All Might asked if Izuku was suited to an internship with Nighteye, Mirio said that he had been thinking Nighteye would like Izuku from the very beginning. Mirio is eager to help Izuku succeed, offering lots of tips and bits of advice before introducing him to Nighteye.

It is currently unconfirmed how much Mirio knows about Izuku and One for All. He seemed certain that Izuku would meet Sir, All Might's former sidekick, and did not look surprised when the retired No. 1 hero summoned him and Izuku to ask him to intercede for the latter. Mirio also took notice of the scars on Izuku's arms, which were caused by One for All.

Toshinori Yagi
Mirio respects and admires All Might greatly, even after the latter lost his powers, claiming he could not help being happy after being called in by him. Some of his most outlandish behaviors are similar to the energy of All Might's public persona. It is unknown if Mirio is aware that he was the top prospective candidate for One for All.

Sir Nighteye
Mirio works under him for his internship. Sir Nighteye views him as a full-fledged student with an immense potential, making him believe that Mirio deserves to inherit One For All.
