Team Up Mission
- Badass Teacher: All of them are or were pro heroes, so this is a given.
- Big Damn Heroes: They show up at the end of the USJ Arc when Iida comes to find them and reveal that villains are attacking. Their appearance is threatening enough for Shigaraki to cancel the attack on sight.
- A Day in the Limelight: They get a chance to show their individual powers and combat styles in the Final Exams Arc.
- Drama-Preserving Handicap: This is invoked when they fight the students during the final exams. They put on devices that add half their body weight to their movements. It's pointed out that the fights would be over too quickly and the students couldn't be sufficiently graded if the teachers went up against them without a handicap. All Might suffers doubly with this one due to his weakening powers and heroic build. He makes a particular point of noting how much they're slowing him down. Despite this, he's still insanely fast.
- Secret Keeper: The hero teachers, principal, and nurse are some of the only people in the world who knew of the limits on All Might's power before it was publicly exposed during his fight with All For One.
- Two Girls to a Team: Recovery Girl and Midnight are the only known female members of the faculty at U.A. Although later retroactively averted, when a character book confirmed that Thirteen (who has never been seen out of costume) is also a woman.
U.A. Homeroom Teachers
Shota Aizawa — Eraser Head
Voiced by: Junichi Suwabe (Japanese), Alex Organ (English, Season 1), Christopher Wehkamp (English, Season 2 onward), Ernesto Rumbaut (Latin American Spanish/TV series), José Arenas (Latin American Spanish/Movies)
Debut: Chapter 5 (Manga), Episode 5 (Anime)
Playable in: My Hero One's Justice, My Hero One's Justice 2
Class 1-A's homeroom teacher. He's a bit of a Lazy Bum, but looks out for his students and pushes them to improve.
Aizawa is also the pro hero Eraser Head. His Quirk, "Erasure", allows him to nullify others' control over their Quirks just by looking at them. Blinking dispels the effect of his Quirk and using it gives him very dry eyes.
- 24-Hour Armor: Downplayed. Aizawa often skulks around off-duty in his hero costume, minus his goggles, which he uses whenever he's in combat, and is rarely seen wearing anything else. When he's turned in for the night, though, he wears pajamas like any other normal person would.
- Amputation Stops Spread: After being shot by a Quirk-erasing bullet, he has to cut off one of his legs in order to save his Quirk from being destroyed.
- Airplane Arms: He runs like this while fighting.
- An Arm and a Leg: He cuts off one of his legs in Chapter 282, after it's hit by a Quirk-Eraser.
- Anti-Magic: His Quirk effectively nullifies one other person's Quirk, as long as it's an emitter or transformation Quirk.
- Apathetic Teacher: Played with. He appears to be one at first. However, it's shown that he has very high standards for his students when it comes to heroism, seriously pushes them in that regard, and is willing to stick his neck out for them when there's trouble. That said, he's still a Lazy Bum who falls into complete apathy when it comes to subjects he considers irrelevant, and on off days, he would rather curl up in a sleeping bag than put up with the Wacky Homeroom.
- Artificial Limbs: After hacking off his right leg to avoid the spread of a Quirk-erasing bullet, Aizawa received a mechanical replacement with digits and joints.
- Ascended Extra: Downplayed. While he's a main supporting character in the main series, he's a full-on main character in My Hero Academia: Vigilantes, having multiple chapters focused on him and his past.
- Badass Baritone: Aside from being a very formidable Hero, Aizawa also has a pretty deep voice, courtesy of Junichi Suwabe.
- Badass in Distress:
- During the battle at USJ, Aizawa is beaten to the ground by Nomu, having both of his arms broken and his face smashed into the ground, making him essentially a hostage. This still doesn't stop him from using his Quirk to erase Shigaraki's power when the villain tries to hurt on of his students though.
- During the raid on the Hassaikai's headquarters, Aizawa is hit by Chronostasis' Quirk leaving him barely able to move for the duration of an hour. Afterwards, the yakuza keeps Aizawa blindfolded to prevent him from using his Quirk. He's saved by Tamaki Amajiki, a.k.a, Suneater, who immobilizes Chronostasis.
- Badass Teacher: Although his teaching methods can be rather questionable, Aizawa is a very competent pro hero who is protective of his students.
- Bandage Mummy: After his grievous injuries in the USJ Arc, Aizawa spends the U.A. Sports Festival with his entire face and both arms wrapped in bandages as he recovers.
- Big Damn Heroes:
- A downplayed example. When Midoriya is about to be killed by Eri's uncontrollable Quirk, Aizawa uses his own Quirk to deactivate it, saving Midoriya and Eri.
- He does it again when Shigaraki grabs Ryukyu to turn her to dust, appearing in a nick of time to disable Shigaraki's Decay.
- Boke and Tsukkomi Routine: Has this routine going on whenever he crosses paths with Ms. Joke, much to his annoyance. Even though he never hits her, he continuously corrects her with cold exasperation and telling her to shut up.
- Brutal Honesty: Aizawa never pulls his punches with the truth, especially when it comes to pointing out flaws or naivete. He never does this out of malice, because his main goal is to ensure that the students learn quickly they're entering a profession with some very harsh realities and need to take things seriously.
- However, he tells Deku and Mirio to purposefully avoid this after Overhaul is defeated — Eri was already blaming herself for the entire incident, so it would just be too cruel to tell her what happened to Nighteye.
- Bunny-Ears Lawyer: Often teaches while still inside a sleeping bag. He is also willing to expel entire classes if he feels that they don't meet his very high standards. This is all overlooked thanks to U.A.'s own policy of academic freedom.
- Caltrops: During the Final Exams Arc, he uses these after capturing and suspending Todoroki in the air and preventing him from escaping and landing safely.
- Can't Hold His Liquor: In one School Briefs story, he claims that he can't recall ever getting drunk. Later in the same chapter it's revealed that this is because he goes from sober to blackout wasted while skipping all intermediate steps, so yes, he doesn't remember being drunk.
- Celebrity Is Overrated: Dislikes the attention of the media, believing that it gets in the way of his job as a hero. This results in him being very obscure to the general population.
- Charles Atlas Superpower: Not prominent, but he would have to have this to take on villains that can smash through walls and even level buildings with their Quirks as well as handle the exceptionally powerful and strong members of Class 1-A. He also survived a beating from Nomu, a monster that could go toe-to-toe with All Might, albeit with lasting consequences.
- Cheshire Cat Grin: Occasionally flashes a mischievous, creepy-cute, toothy grin during his Troll or "logical ruse" moments.
- Childhood Friends:
- Aizawa and Present Mic have been best friends since at least their freshman year of high school. A volume extra flashback shows that Mic is the one who named him Eraser Head.
- During his time at U.A., Aizawa formed a young team of three with Yamada and Shirakumo, which was eventually broken through the latter's death in their second year. The reveal that Kurogiri is a Nomu-fied Shirakumo hits both of them extremely hard.
- Cloth Fu: His scarf isnt just a fashion statement, its a support item he uses to tie opponents up, or to set up traps.
- Combat Commentator: During the U.A. Sports Festival, he sits in the announcers booth with Present Mic, although he lets Mic do most of the commentating and only chimes in when necessary.
- Combat Pragmatist: Since his Quirk only erases someone else's, Aizawa is completely fine using it at any time or way to win against his foes. This is best shown during the USJ Arc when he purposely waits to use it in order to give himself an advantage.
- The Comically Serious: Will take things like Nezu climbing out of his scarf with the straightest of faces.
- Cool Shades: Wears a pair while working as a hero, with the intent to keep his opponents from knowing who he's looking at. Particularly useful against a crowd.
- Cool Teacher: He's a pretty badass underground hero and teacher overall, but this especially applies to his relationship with Shinso, who admits to idolizing Eraser Head and officially becomes his apprentice after the Sports Festival. Present Mic even comments on how similar they are in personality and mannerisms.
- The Cowl: His general design is based on this, being an underground hero that avoids media attention and works as a Foil to All Might.
- Cruel to Be Kind: His way of teaching is that it's better to be mean and unfair to the students to help prepare them for the future of dealing with natural disasters and villains. He is more than willing to destroy a student's dream of being a hero if he finds they have no potential, but only because it would be wrong to give them false hope for the future or worse for them to go into real world with no hope of surviving.
- Cynicism Catalyst: The death of his best friend and battle partner during a mission is what finally drove Aizawa to drop all plans of joining a hero agency and aim for a solo career. The only reason he is back at UA as a teacher is because he was incessantly nagged into it by Present Mic and Midnight, who thought he would benefit from it mentally.
- Deadpan Snarker: Aizawa occasionally drops dry quips in order to shrug off things he finds foolish or otherwise grating, most notably Mic's antics. After Midoriya and Bakugo's big fight, he is obviously pissed, but he doesn't raise his voice at all. Instead, he sarcastically congratulates the two for having enough energy left to go all out against each other, despite having the preliminary hero licensing exam, while restraining them with his scarf, which is not a comfortable situation.
- Death Glare: He does this when he's angry. Due to the nature of his Quirk, this will also render whoever he's looking at Quirkless.
- Dented Iron: Following his extreme injuries after the attack of the USJ, his Quirk becomes unstable, meaning he can't keep it active as long and has to take brief breaks between uses.
- Determinator: Shows up in the USJ Arc, even after pushing his Quirk to the limit and taking a severe beating by Nomu, including having his head repeatedly slammed into concrete, he still manages to stare at Shigaraki, preventing him from using his Quirk to kill Tsuyu.
- Taken Up to Eleven in the Paranormal Liberation War Arc, when he goes so far as to cut off his own leg as to not lose his Quirk and keep nullifying Shigaraki.
- Deus Exit Machina: During the Internship Arc. While not really the most powerful man in the room, Aizawa is absent or held captive by Chronostasis during Overhaul's fights with Mirio and Midoriya, as Aizawa knocking out Overhaul's Quirk would end the battles too quickly.
- Disappointed in You:
- Towards Class 1-A after the hideout raid: Out of the 20 students in the class, five of them decided to break all possible rules and save Bakugo by themselves, while 12 other students knew, none of them reported them (although Tsuyu believed she had talked them out of it). He said that he was more than willing to throw away all of them, but will not due to the circumstances, and says it will take a long time until he is able to trust them again.
- He gives an even harsher verbal tongue lashing to Midoriya and Bakugo when they get in an unsanctioned brawl. Aizawa still hasn't let Midoriya off the hook for this incident and warns him that his maverick tendencies will be punished formally if he does something like this again. As for Bakugo, falling behind the rest of the class with extracurricular hero training is punishment enough.
- Dreary Half-Lidded Eyes: His default eye expression, very rarely changed.
- The Eeyore: He's a massive buzzkill who dresses in shambles and constantly likes to remind everyone that life sucks. It's so bad that when high energy Present Mic pops in to teach his soul-sucked class, there's no hope in trying to bring them back to life after he's reduced them to practically zombies. On his worst days, he even whips out a sleeping bag and curls up in a cocoon, too unmotivated to even teach.
- Embarrassing Nickname: Mic has given him a ton of these, including "Prince of Slumberland" (P.O.S. for short) and "Snooze Master". Aizawa's usual response is to place him in a choke hold until he shuts up.
- Everyone Has Standards: He has a tendency to throw his students into the deep end when training but during the rescue exam when it's revealed that the students have to save people and fight off attacking villains at the same time (something he notes would difficult even for a seasoned pro), even he thinks it's a bit much.
- Eye Scream: Aizawa lost his right eye against the Paranormal Liberation Army and now wears an eyepatch, which has obviously handicapped his Quirk.
- Fights Like a Normal: Although he has a powerful Quirk it doesn't make him naturally tougher or stronger than a baseline human, and has a notable weakness. This means he needs to rely on weaponry, and martial arts, and good tactics.
- Foil: To All Might. All Might is the highest ranking hero in the world and uses his fame to inspire others, while Aizawa has a slovenly appearance and shuns the spotlight. All Might in his prime has incredible strength and stamina, whereas Aizawa has great skill, but prefers to strike quickly and with the element of surprise, as he lacks the endurance for long, protracted battles. Lastly, All Might's power empowers him with the strength of many men, and his personality is to build up those who have the desire to do good. Aizawa's Quirk robs others of their powers, and his personality is to tear down those who he feels show no potential. Their relationship in several ways mirrors the one between American superheroes Superman (All Might) and Batman (Aizawa) with All Might as the mighty superhero who fights his enemies with overwhelming power and Aizawa as the brooding anti-hero who relies more on skill than brute force.
- Fragile Speedster: Aizawa is immensely fast and agile, boasting one of the highest speed rankings of most pro heroes, his battle outfit allows him to ensnare and trap opponents from escaping, has strong martial arts abilities and can shut down other people's Quirks with his own. However, Aizawa has dry eye, his evasive fighting style can leave him open to attacks when he isn't careful, and with his limited stamina, juggernauts such as the Nomu can defeat him in a few moves.
- Freudian Excuse: Vigilantes implies that the death of Shirakumo, his classmate and partner in internship, during a villain attack inspired a lot of his behavior towards his students, such as his hard line and the need to teach them early about the horrors and difficulties of being a hero.
- Game-Breaking Injury: The damage inflicted onto him by the original Nomu in the USJ Arc permanently damages him in such a way that weakens his Quirk for the series, largely by causing his time he can use it to shorten. While he recovers and returns to fighting a few arcs later, in several situations its a major handicap and almost gets him killed once or twice.
- Goggles Do Nothing: Subverted. They seem like mere accessories to the outside viewer, but they make it difficult for others to tell who he's glaring at and thus using his Quirk on. They also keep stuff out of his eyes that could force him to blink like smoke. Illegals shows that this wasn't always part of his costume and he started wearing goggles at the suggestion of his friend, Shirakumo.
- Hair-Contrast Duo: The lazy, cynical, and slovenly black-haired Aizawa to his old friend, the upbeat, energetic, and outgoing blond Present Mic.
- Ham and Deadpan Duo: Tends to have this dynamic with both All Might and Present Mic. While the latter two are very loud and bombastic, Aizawa is surlier, quieter, and more sarcastic.
- He Cleans Up Nicely: When he has to appear before the media, he actually bathes, neatens his hair, and wears a suit.
- Heroic BSoD: Suffered a major one in his school days that he is evidently still healing from, given his reaction to Kurogiri being revealed as a nomu-fied Shirakumo. The experience was so traumatic to him that for a very long time he wanted nothing to do with UA and would lash out at Present Mic or Midnight for suggesting that he work with them.
- Heroic Self-Deprecation: In his school days, he thought his Quirk was weak and mediocre and frequently struggled in exercises and in the field. His confidence took a hit because of this and he frequently berates himself for failing.
- Hypocritical Humor: He tends to tell people to cheer up after he eviscerated their jovial moods. And if other people are already mopey without his doing when he enters a room, he thinks they need to stop moping.
- I Lied:
- Proclaims that the one who ranks last in his exercises on the first day will be kicked out of the school. Then he says he was lying just to get more effort out of them. All Might calls him out on this, pointing out that in a previous year, he had expelled his entire class. Aizawa admits that he would have followed through if the one ranking last showed zero potential to be a hero. Since the one who did rank last, Midoriya, did show some potential in his eyes, he decided to pretend he had been lying.
- He takes great pleasure in telling the students that they will be subjected to "remedial hell" if they fail the end of license exams. Turns out he only meant the written portion of the exams. Those who failed the combat portion of the tests actually need the summer camp the most.
- Informed Attribute: We're told that Aizawa is definitely known for expelling students frequently. Not only has he not expelled anyone in his current class, he has also not hinted at making any attempt to judge who should be expelled beyond the first class, other than the occasional joke "normally I would expel almost the entire class for this, but..."
- Instant Knots: Can manipulate his capture tape so that it instantly wraps around an opponent.
- Introverted Cat Person: Implied — Aizawa isn't one for social interaction. Vigilantes shows him with a shopping bag full of cat food and cat care books, implying he's fond of them. The anime eyecatches also list "cats" as his interest.
- Irony: He balks at both the idea of fairness and the (in his opinion) antiquated sentiment that all Quirks are equal when his own power has the potential to level the playing field.
- I've Come Too Far: In Chapter 298, Aizawa is clearly trying his hardest not to look heartbroken at Midnight's death. However, he knows he can't give up and dwell in sorrow, so he needs to move on and try to protect his students as best as he can in order to not let them die too.
- Jerk with a Heart of Gold: He may be stern and standoffish teacher, but he cares about his students and prioritizes their safety whenever villains enter the picture:
- During the final exam against Yaoyorozu and Todoroki, he allows Yaoyorozu to claim victory for the team instead of capitalizing on her mistake and defeating them, in order to allow her to build up her destroyed confidence again:Recovery Girl: When all's said and done, that man's a softie.
- During the Joint Training Arc, it's confirmed that Aizawa started training Shinso after the U.A. Sports Festival because he believed Shinso had the potential to become a hero like he'd always dreamed. And after an accident occurs during the clash between Shinso's team and Midoriya's, Aizawa is the one who asks that they keep the match going once things settle down, because both of his students still have the desire to win.
- During the final exam against Yaoyorozu and Todoroki, he allows Yaoyorozu to claim victory for the team instead of capitalizing on her mistake and defeating them, in order to allow her to build up her destroyed confidence again:
- The Killjoy: Aizawa has made it his mission to prepare his students for the rigors and cruel realities of hero work, even if it means crushing their dreams with scathing criticism, threatening them with expulsion for bending the rules, and literally dragging them off to remedial classes. There are times when his coworker, Present Mic, walks into Class 1-A to find the class reduced to lifeless zombies because of the sheer negativity Aizawa exudes. This is also deconstructed, as his Sink-or-Swim Mentor and Stern Teacher tendencies backfire at several points in the story, and he admits that his counterpart in Class 1-B, Vlad King, is a better teacher than he is.
- Laser-Guided Karma: After spending the entire series disciplining his students and doing his best to protect them from villains, Midoriya and Bakugo tackle Shigaraki just as the latter is about to kill him. Both boys declare that this time, it's their turn to save him.
- Lazy Bum: Introduced sleeping on a floor in front of his classroom in a sleeping bag. He also often teaches while in said sleeping bag.
- Life-or-Limb Decision: After being hit by a Quirk erasing bullet from Tomura, Aizawa is forced to immediately amputate his right leg below the knee to protect his Quirk.
- Locked Out of the Loop: He is not one of the select few who knows the secret of All Might and Midoriya's Quirk. He has come to realize there is a connection between the two, but he doesn't know exactly what it is. And he is pretty suspicious when All Might volunteers to go break up the fight between Midoriya and Bakugo.
- Logical Weakness: Aizawa's Quirk is powerful, but he must keep his eyes open for the effect to persist. Blinding or binding up his eyes makes it impossible for him to use it, and depriving him of sleep or forcing him to stare at a single person for an extended period of time will make his eyes tired and thus reduce the effectiveness of his Quirk. Even normal use puts wear and tear on his eyes, so he constantly carries eye drops.
- His Quirk works on Emitter and Transformation Quirks, but not Mutation since they mutate the body's physical structure and thus are permanently active.
- His power is obviously useless against a well trained fighter who doesn't rely on a Quirk. All he can do then is rely on good tactics, equipment, and his own impressive martial arts skills and hope it's enough.
- If somebody sees who he's looking at, they can anticipate the use of Aizawa's Erasure. This is why Aizawa uses his one-way goggles to shield his line of sight from view as a workaround.
- Aizawa's hair stands on end when his Quirk is active, which allows for opponents to note when he's using it even if they can't see who he's using it on at the moment.
- He needs to actually see the person. As such, clothing that fully covers the body, like heavy hooded cloaks, will protect one from his Quirk.
- Finally, his Quirk working on only one person at a time is a problem when dealing with multiple opponents. He gets around this to an extent with impressive hand-to-hand abilities, while switching his Quirk target for maximum effect, but like any other martial artist, he can be overwhelmed by sheer numbers or simply an opponent naturally much stronger or faster than him.
- Magical Eye: It's by looking at someone that he can erase Quirks. It is for this reason he is asked to look after Eri, a little girl with a dangerous uncontrollable Quirk, since he can quickly nullify it before it causes damage.
- Meaningful Name: His given name has a character that means "erase", while his last name contains a character that can mean "councillor". The first syllable of his last name, "Ai", is also a homophone for "eye", the source of his Quirk.
- Mentor Archetype: Deconstructed because he is not an endlessly wise and patient teacher figure, but someone who fails at guidance at times, and has a personality and life that exists outside of his job as a teacher.
- He's an extremely strict Sink-or-Swim Mentor, though that's primarily a result of him not being an experienced teacher. The only reason he even became one in the first place is because Midnight talked him into it in Vigilantes. On some days he's too unmotivated to even stand up in front of the class, instead leaving them to their own devices while he naps in the corner.
- His stern demeanor makes it hard for his students to determine whether or not he is being sincere in his methods, so when he tries to be a Trickster Mentor with his "rational falsehoods", they mistake him for being serious and understandably get scared. The fact that he has expelled many students in the past makes it harder to tell when he's bluffing.
- While he tries to take care to observe whether or not his students are in despair, he doesn't always notice, and his actions don't always make things better when he does:
- He notices that Iida specifically chose to intern under Manual in Hosu, even though Iida could have chosen higher-ranked heroes, and finds it odd that Manual was Iida's only choice, but fails to pick up on the connection between Hosu and Stain's last known whereabouts.
- He notices the tension between Midoriya and Bakugo when assigning teams for the final exams and understandably thinks pitting them against All Might will force them to pull an Enemy Mine, if not become Fire-Forged Friends. However, doing this almost cripples both of them thanks to All Might's inability to hold back, and their issues don't even come close to getting better.
- He doesn't pick up on Bakugo's issues following his kidnapping, nor the issues with putting him through the provisional hero license exam where one of the tests is a recreation of Kamino Ward, the location of the event that took place as a result of his kidnapping. As such, this leads to the fight between Midoriya and Bakugo later on.
- This is acknowledged in-story during the Joint Training arc, as he calls Kan, his counterpart in Class 1-B, a flat out better teacher than him.
- Mentor in Sour Armor: His usual attitude towards his students is getting them familiar with the high-stakes harshness of fighting villians, responding to deadly disasters, etc. so they can prepare for it. Those that can't handle it are better off dropping out now before they die.
- Messy Hair: His long disheveled hair adds to the Lazy Bum image.
- Motivational Lie: He passes off his lie of threatening to expel the student in last place as this when he changes his mind.
- Mundane Utility: His hair stands on end when he uses his quirk, which he'll use to keep his hair from tangling in his scarf.
- Nerves of Steel: Even when he's fighting for his life and the lives of his students, he retains a stoic composure. Very little seems to faze him, not even the huge explosion from the Todoroki vs. Midoriya fight at the U.A. Sports Festival.
- Ninja: From his fighting style (slow down his opponents with Status Ailments, then snag them to either restrain them or beat them into submission as quick as possible, similar to Bujinkan Ninjutsu and Chikari no Jutsu), to his preferences in staying anonymous to prevent people predicting his moves, the use of caltrops to deter a restrained Todoroki during his final exam, even the fact that he sleeps on his left side in his sleeping bagnote and his affinity for catsnote all point to Aizawa essentially being a ninja hero.
- No Badass to His Valet: His past history with Ms. Joke makes it so that she leisurely screws with his nerves without fear of consequence.
- Obfuscating Stupidity: Seems like an offbeat fellow but can get just as serious when the time comes.
- Odd Friendship: He and Mic are good friends despite their clashing personalities; they actually have been friends ever since they were classmates at U.A.
- One-Man Army: Surrounded by villains with a few that can't be stopped by his eraser power. Doesn't stop him in the slightest as he reveals he excels at hand-to-hand even without his Quirk. That said, he admits that he isn't really equipped to handle large groups in open combat for long and did eventually get overwhelmed.
- Only Sane Man: Aizawa consistently tackles problems that are not glamorous enough to get the attention of the other faculty. He notices that the entrance exam discriminates unfairly against Quirks that aren't battle-oriented, and strives to prepare his students for harsh realities that All Might and co. tend to gloss over.
- Origins Episode: He has an origins arc in Vigilantes, showing his time during second year of U.A. and getting into an internship with Midnight and Shirakumo, as well as how he grew into his current mindset. The death of his classmate during a villain attack influenced all of it.
- Papa Wolf:
- Much like with All Might, attacking his students is a good way to end up in the hospital. During the USJ attack, despite being badly wounded by a huge and muscular Nomu, he was able to muster the Heroic Willpower to save Tsuyu from being disintegrated by Shigaraki. He was also angered by the crowd during the fight between Uraraka and Bakugo, telling those that booed Bakugo for supposedly bullying Uraraka that they shouldn't be heroes anymore, because not only did they not notice Bakugo was playing it safe, but because none of them had noticed Uraraka had been setting up a big attack.
- When staring down Shigaraki, Aizawa is not doing it out of a sense of duty as a hero, but to remove an obstacle that is threatening the futures of his students.
- Paper-Thin Disguise: He's virtually unrecognizable to the public and to even hardcore hero fans like Midoriya without his distinctive goggles. This is justified in that he's an underground hero who primarily operates at night. Due to his black ensemble along with his rapid movements, the only real discernible features on him would be his capture device, and his goggles. In the daytime, however, he simply looks like a scraggly insomniac wearing a thick scarf and sweats.
- Parental Substitute:
- Downplayed. U.A assigns him with the main responsibility of looking after little Eri because his Quirk is the only reliable way to stabilize her should she ever lose control over her Quirk. As a result, he acts as something of a guardian figure, bringing her to class events and looking out for her general well-being.
- To Shinso Hitoshi. After noticing his potential during the Sports Festival, Aizawa decides to train Shinso one-on-one as his apprentice and help him transfer into the Hero Course. Not only does he teach Shinso how to best utilize his mental quirk with close combat fighting, but he also trains him in how to use his trademark — and notoriously difficult — capture weapon. By the Joint Training Arc, Shinso looks and acts like a younger version of Aizawa, right down to the tired eyes, slouched posture, and capture scarf.
- Perma-Stubble: Aizawa has five-o-clock shadow going nonstop. When he is seen clean shaven after the summer training camp incident, it's a clear sign things have gotten bad.
- Pet the Dog: After Midoriya feels bad about not being able to save Eri, Aizawa offers him some reassurance that they can still save her, they just need more time and preparation to do it.
- Power Incontinence: How his Anti-Magic works. It doesn't actually nullify the power itself; rather it nullifies the control over said power. Thus it works on Emitter and Transformation, but fails on Mutation Quirks.
- The Quiet One: He tends to be much quieter and more socially withdrawn than his friends and coworkers. This is especially evident with Present Mic and All Might, who frequently annoy Aizawa with their loudness and bombastic personalities.
- Reasonable Authority Figure: Stern as he is, he isn't unfair. His past habit of expelling students was because he felt that it would be far more cruel to keep someone with no potential in the hero program when the end result for them would either be failure or death at the hands of a villain. In Vigilantes, which takes place before he started teaching at U.A., he runs into Koichi as "The Crawler" during a villain attack. Though he's obligated by the law to treat him as a villain for using his Quirk to fight without a license, he ultimately lets it slide because Koichi helped him out.
- Red Eyes, Take Warning: His eyes glow red when he's using his Quirk. Personality-wise, he's one of the sternest teachers at U.A. and is fully willing to expel his entire homeroom class should they step out of line or fail to meet his expectations.
- Red Oni, Blue Oni: The cool-headed blue to Present Mic's hot-blooded red. Because of his personality, he winds up being the Blue Oni to most people he's with. Lampshaded by himself:Aizawa: (about Ms. Joke) Why am I always surrounded by these annoying types...
- Renowned Selective Mentor: All Might mentions that he once expelled an entire class of students that didn't meet his standards. Midoriya was spared the same fate only after he managed to impress him at the last moment.
- Scare 'Em Straight: Chapter 254 reveals that he not only has free reign to expel students, but also to re-enroll them, and he temporarily expels students in order to scare them into behaving and applying themselves properly. He says he believes students should experience this thing, and the 2-A students, apparently composed of a number of students he expelled and brought back, believe it helped them grow.
- Scarf of Asskicking: A multi-layered one around his neck which he uses to bind his opponents.
- Scars Are Forever: Of all the wounds he received during the battle at USJ, the one that has stuck around was a horizontal scar under his eye. Though he always wears long sleeves so we don't know what his arms look like after all that happened to them.
- Seriously Scruffy: Aizawa looks incredibly disheveled and miserable for the most part. However, if forced to go before the press, he will attempt some degree of maintenance with his looks... then go right back to his old self as soon as he doesn't need to look good for the cameras anymore.
- Sink-or-Swim Mentor: Will expel entire classes if they're not up to his standards, and is not above showing tough love to the students that do meet them. For example, he doesn't warn Class 1-A in advance that other hero schools will be out to get them during the license exams, or that the competition knows about their Quirks for their own self-development.
- Sleepyhead: He has a habit of dozing off anywhere and anytime, dragging his sleeping bag around for this reason. Sometimes he can't even bring himself to teach, swaddling himself up and letting Iida and Yaoyorozu take over. For this reason, Present Mic gives him nicknames like "Prince of Slumberland" and "Snooze Master". Possibly justified in that the majority of his Hero work tends to be done at night, so between Hero work and his teaching position he probably doesn't get many opportunities to get a normal amount of sleep.
- So Proud of You:
- When Yaoyorozu gets her confidence back and resolves to defeat him during her final exam. He doesn't say anything, but his smile says it all.
- When his entire class passes the first round of the provisional hero license exam, his response is basically "took them long enough", which Ms. Joke teasingly translates as "I knew all of you could do it".
- Spell My Name with an "S": His first name can be spelled "Shōta", "Shota", or "Shouta".
- The Spock: His actions and thoughts are governed by logic, paying little heed to social or emotional factors. The light novels even refer to him as someone who tries to live as rationally as possible, putting in as little effort as necessary and napping when there's nothing to do.
- Stern Teacher: At first, he seems to be an Apathetic Teacher, but it eventually comes to light that he just has high standards and very low opinions of those who don't meet them.
- Story-Breaker Power: Almost all of the really powerful and dangerous Quirks are not mutation Quirks (Quirks that alter people's bodies as a default not a transformation) which also happens to be the type of Quirks Aizawa's ability works on. If he had been present with the other heroes when All For One showed up while the good guys were trying to rescue Bakugo, then the fight would have lasted for all of 5 seconds. His Quirk robs you of the ability to access and control your Quirk (which is why it doesn't work on Quirks that permanently mutate people as it isn't something that they can control) which means that none the big bads would have a chance against him one on one. If he didn't have any Logical Weakness built into his ability and the way it functions, then the big time villains would never have a chance of beating the heroes.
- The Tell: His hair inadvertently reveals what his Quirk's weakness is during the USJ Arc.
- Tough Love: His teaching style in a nutshell. He calls out failures, expects high performance, crushes naivete, and rarely gives praise. On the other hand, hard work is acknowledged, advice is given, eccentricity is accepted (to a point), emotional problems are understood, unfair outside critics will be silenced, and he will go to the bat to protect his students from danger. He can be harsh, but he does it only to help the students become strong enough to handle the unforgiving world of pro heroes as quickly as possible.
- Tragic Bromance: With Oboro Shirakumo, a close friend and classmate of his and Yamada's who died during their second year at U.A. Aizawa became much more socially isolated, combat-oriented, and cynical of other heroes and the hero industry as a whole after Shirakumo's death, effectively shaping him into the brutally efficient underground hero he is in the present day.
- Tragic Keepsake: His goggles. They are a design suggestion from his deceased classmate Shirakumo, and they were supposed to use them together to symbolize their partnership.
- Tsundere: He's a Type A to his entire class, being grouchy and stern all the time while concealing how much he believes in them and worries about them. Ms. Joke teases him about it.
- Used to Be a Sweet Kid: As shown in Vigilantes, Aizawa was still dour in his school days, but he was timid and lacked confidence while trying his best to be a good hero despite repeated failures. He looked to others like Shirakumo and Yamada for support and was a dorky, sweet guy overall. In the present, his experiences have hardened him to be gruff and no-nonsense on the job to the point of being The Eeyore.
- Villain Respect: Due to his status as a One-Man Army and Determinator, Aizawa seems to be the one hero that Shigaraki actually respects.
- Vitriolic Best Buds: The light novels reveal him to be this with Mic. Mic constantly annoys Aizawa by giving him Embarrassing Nicknames, singing and rapping in Aizawa's ears while he's trying to nap, and dragging him into conversations he wants no part in. Aizawa responds to this by placing Mic in choke holds until he shuts up (which usually fails in the long-term anyways). Despite this, they're the other's closest confidants and the two hang out together more often than not.
- Weak, but Skilled: Since his Quirk doesn't boost his abilities in any way, Aizawa combines it with hand-to-hand combat. It makes him lethally effective since he is extremely smart on when to use it. Fittingly enough, this contributes to his Foil nature with All Might. It also applies to his fighting style. He has to rely on his impressive speed and agility, preferring stealthy ambushes to straight up brawls, due to his slender build.
- Weaksauce Weakness: His Quirk would be even more useful if he didn't suffer from dry eye.
- What the Hell, Hero?:
- He gets one from All Might, who points out that Aizawa was lying when he claimed that his threat of expelling the lowest-ranked student was only a bluff. Aizawa explains himself, but while All Might isn't convinced, he decides to Agree to Disagree with Aizawa.
- In the aftermath of the Hideout Raid Arc, he states that were it not for All Might's retirement, he would not just have expelled Midoriya, Kirishima, Iida, Yaoyorozu, and Todoroki for making an unsanctioned attack on the League of Villains, but every single student in Class 1-A save Hagakure, Jiro, and Bakugo simply for knowing about the plan and doing nothing to stop it.
- When He Smiles: Disheveled, aloof to the near point of apathy, and perpetually melancholic, Aizawa rarely shows how much he cares about his students and their development into heroes. But when they show flashes of reaching their potentials and his high expectations, expect to see a mischievous smile appear on his face.
Sekijiro Kan — Vlad King
Voiced by: Shuuhei Matsuda (Japanese), Ben Bryant (English), Héctor Almenara (Latin American Spanish/TV series)
Debut: Chapter 20 (Manga), Episode 13 (Anime)
Quirk: Blood Control
The homeroom teacher of Class 1-B. His Quirk is "Blood Control", which allows him to control blood.
- Bad Powers, Good People: Manipulating and weaponizing blood is hardly a heroic power, but he is still a pro hero and a teacher.
- Badass Baritone: He is a huge, strong hero with a deep, imposing voice.
- The Big Guy: As imposing and solid as Endeavor.
- Bilingual Bonus: His surname, Kan, means blood, but in Turkish.
- Bloody Murder: He can weaponize blood.
- Characterization Marches On: Early in the series, Vlad King's one sided rivalry with Class 1-A and Aizawa is a fairly minor bit of jealousy and barely gets mentioned. By the time of the Class 1-A vs. Class 1-B exercises, Monoma's rubbed off on him enough to the point where he can't say anything good about Class 1-A and believes even the most pathetic accomplishments make them better. Ashido calls him out on this multiple times.
- Cool Teacher: Very supportive of his class and beloved by his students, particularly Monoma. He proves highly adept in teaching Class 1-B strategy and team maneuvers, which show fruit in the joint training where Class 1-B displays superior tactics and teamwork compared to Class 1-A. Aizawa even admits that Vlad King is a better teacher than he is.
- Fang Thpeak: Not obvious in the original Japanese, the English dub does give him this speech pattern.
- Fangs Are Evil: Inverted. He has a pair of conspicuous fangs sticking out from his lower jaw but he's a seasoned pro hero and is firmly on the side of U.A.
- Heroes Love Dogs: It's mentioned in his profile that he has a dog at home.
- Heroic Build: A tall and conspicuously muscular man.
- Large Ham: Proves to be this in the Joint Training Arc, much to Class 1-A's annoyance.
- Meaningful Name: Kan is Turkish for blood. His name also contains the kanji to "vessel", "red" and "love", mostly referring to his powers of manipulating blood. His hero name is "Vlad King," a reference to Vlad the Impaler, the inspiration behind Dracula.
- Not So Above It All: He mostly acts in a professional manner, but when the rivalry between the two hero classes heats up, he's almost as bad as Monoma.
- Our Vampires Are Different: He has fangs like a vampire and a blood motif, but none of the other classic vampiric traits.
- Perpetual Frowner: Before the Joint Training Arc, he constantly harbored a scowl on his face and seemed displeased or angry all the time. Even his resting face during the press conference was just a slightly less threatening scowl. He still sports a scowl during the Joint Training Arc, but he also starts having more gleeful expressions as he brags about his class's skills.
- Red and Black and Evil All Over: Inverted. He is mostly clad in red with black details, even his eyes are red and he seems to have a permanent scowl, but he is a hero nonetheless.
- Red Is Heroic: A blood-red costume and a known hero and teacher.
- Shout-Out: To the Romanian Prince Vlad Tepes, who inspired Dracula, hence his hero name and blood-based Quirk.
- Sitcom Arch-Nemesis: With Aizawa. While Aizawa hardly minds him, Vlad King is constantly competing with the former to make his class stand more than Class 1-A, who has the attention of both the school and the media. That doesn't prevent him from closing ranks with Aizawa against a common threat though.
- Spell My Name with an "S": His hero name has also been spelled "Blood King", and even "Brad King", because Japanese doesn't have V or L sounds in it naturally.
- "X" Marks the Hero: His lower left cheek sports an X-shaped scar.

Hizashi Yamada — Present Mic
Voiced by: Hiroyuki Yoshino (Japanese), Sonny Strait (English, Season 1), David Trosko (English, Season 2 onward), Jorge Luis García (Latin American Spanish/TV series)
Debut: Chapter 3 (Manga), Episode 3 (Anime)
A hero who doubles as a DJ. Usually plays the role of event announcer whenever one is required. He is also an English teacher.
His Quirk is "Voice", which allows him to heighten the loudness of his voice for offensive purposes.
- Anime Hair: His hair is some sort of reverse pompadour that is three times bigger than his own head. This is actually only part of his hero costume, a sketch of him with casual clothes shows his hair is usually down and he is pretty normal looking.
- Bad "Bad Acting": His acting is just as loud and over the top as everything else about him.
- Badass Teacher: Besides being a pro hero and radio DJ, he's also bilingual in Japanese and English and is U.A.'s English teacher. Unfortunately for him, most students find his subject material — grammar, conjugations, etc. — to be less than thrilling.
- Beware the Silly Ones: He might be the Life of the Party, but he's still a teacher at U.A. and has the skills to prove it. He also marks as 5/5 on the "Intelligence" stat and is the first one to point out that there's a traitor at U.A. and states his reasons to think so.
- Big Word Shout: Justified as his Quirk is making his own voice louder:Present Mic: YEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHH!
- Big "YES!": This is actually one of his attacks, where he simply screams "YEAH!" at an enemy as loud as he can. With the way his Quirk works, it's actually pretty effective.
- Catchphrase: "Everybody Say Hey!"
- Childhood Friends:
- With Shota Aizawa. They've known each other since freshman year of high school and are still very close friends who enjoy working together. Vigilantes shows that they also knew Nemuri Kayama while at U.A., although she was one year ahead of them.
- Another close friend of theirs from high school, Oboro Shirakumo, was believed to have died during their second-year, but it's later revealed that he may in fact be Kurogiri, who is now a Nomu and appears to share a base Quirk with their deceased friend.
- Combat Commentator: Provides running commentary on the events of the U.A. Sports Festival, including the one-on-one matchups that happen in the final stage.
- Cool Car: Mic drives a 1966 Ford Mustang Shelby GT350, perhaps one of the flashiest examples of classic American muscle cars anybody could own.
- Cool Shades: Wears these as part of his hero attire, but not while in plainclothes.
- Crouching Moron, Hidden Badass: He's usually depicted as an obnoxious moron with an unavoidably loud voice. At the same time though, his Quirk is nothing to sneer at, as shown when he uses his Quirk to blow out the villains' eardrums and a good chunk of the stadium during one of their attacks. He's also not as dumb as he lets on, as he marks as 5/5 on the "Intelligence" stat.
- Dumbass DJ: He can be obnoxiously loud at times. Aizawa definitely thinks so, anyways.
- Early Personality Signs: Apparently he had his Quirk from birth. When he was born, his cry was so loud it damaged the ears of his parents and the doctor who delivered him.
- Filling the Silence: An in-universe example. Mic cannot be bothered to sit still in silence. He will go absolutely berserk and do anything in his power to fill the void of silence.
- Gale-Force Sound: One of Present Mic's most powerful attacks, "Loud Voice," is effectively a sonic boom that blasts away nearly anything in its path.
- Good Is Not Soft:
- Recovery Girl isn't a fan of his involvement in the final exams, because he's one of the reasons why her services are needed most after the exams conclude. He screamed until he made Jiro's ears bleed.
- He's pretty quick to suggest that they beat up the reporters who trespassed onto U.A. property. Aizawa tells him to stand down and just wait for the police to arrive.
- Mic has absolutely no qualms about beating the ever-loving shit out of the elderly Quirk doctor who was behind Shirakumo's death and eventually admits to having been after Aizawa's Erasure Quirk all along.
- Gratuitous English: Sometimes spouts random sentences in English. Incidentally, he's also Class 1-A's English teacher.
- Hair-Contrast Duo: Upbeat, energetic, and outgoing blond Present Mic to his old friend, the lazy, cynical, and slovenly black-haired Aizawa.
- Hell-Bent for Leather: Almost his entire hero costume consists of black leather, including his jacket, gloves, pants, belts, and boots. He even seems to favor a red leather jacket during his time off, too.
- Large Ham: Even without using his Quirk, he's very on the loud side.
- Large Ham Announcer: Of the entrance exams and the U.A. Sports Festival. Naturally, this has even carried over into video games.
- Life of the Party: He's relentlessly cheerful, loves drinking, and can't help but try to socialize with everyone around him. He's one of the first to invite others to the bar with him and drags Aizawa into them against his will.Yamada: What are days off for, if not hangovers?
Aizawa: Literally anything else.
- Living Emotional Crutch: Heavily implied to have become one to Aizawa after Shirakumo's death. When Aizawa stopped socializing with their classmates and spent nearly all of his time training, Yamada was the only one who truly stuck by his side and tried to help him work through the grief. Between him and Kayama, they eventually convinced Aizawa to teach at U.A., rightly believing that it would be good for his mental and emotional health.
- Make Me Wanna Shout: He can amplify the loudness of his own voice. When he was born, his cries ruptured the eardrums of his parents and the doctors. He also has a directional speaker mounted on his neck to control where his sound wave attacks go.
- The Narrator: Downplayed since the series doesn't really have a consistent narration aside from Midoriya's occasional inner monologues, but in the anime, he provides voiceovers revealing the names of other characters' Quirks and explaining how they work. Concerning his Quirk, it's Aizawa who provides the voiceover.
- No-Holds-Barred Beatdown: He delivers a brutal one in Chapter 269 to the doctor who was responsible for Shirakumo's death and Aizawa's emotional breakdown.
- No Indoor Voice: His Quirk is all about being loudmouthed, and he's a career DJ who thrives on being loud and lively. Except it doesn't translate well to the teaching atmosphere when he's irreverently loud for the occasion.
- Obfuscating Stupidity: Often acts like a loud-mouthed airhead while in public, but it's shown at various points that he's much more observant and clever than most people realize. Not only is Mic the first person to suspect a traitor among the U.A. staff, but he also has a very good people sense and quickly puts the pieces together regarding the connection between their deceased high school friend Shirakumo and the League of Villains' Kurogiri.
- Odd Friendship: He and Aizawa are best friends despite their clashing personalities. They've known each other since their freshman year at U.A. and are incredibly in-tune with one another's fighting styles.
- OOC Is Serious Business:
- He's usually the Life of the Party wherever he goes and literally can't bring himself to sit down and be quiet, so if Present Mic isn't smiling or joking around, then that's usually a major indicator that something really serious is going on.
- When the pro heroes pull their Big Damn Heroes entrance at USJ, it's the first time Mic is shown looking totally calm and serious while his best friend's mangled body is being cared for directly behind him. Mic then proceeds to blow out the villains' eardrums and a good chunk of the stadium after that.
- When he relays information to Aizawa that Kurogiri's Quirk appears to share a base Quirk from their deceased friend Shirakumo, thus possibly implying his identity and that he was experimented on in a similar manner to the Nomu, he's entirely stern and serious to the point that he has to tell Aizawa to calm down.
- In the aftermath of the above, Mic lays on the couch face down, simultaneously emotionally exhausted and furious. And once the raid on the hospital begins, it's finally shown that Mic has been suppressing a whole mountain of rage for a very long time.
- Personality Powers: Mic has the capability to make his own voice louder, and is fittingly the Life of the Party.
- Pop-Cultured Badass: Comes naturally with his schtick as a famous radio DJ and combat commentator for one of the largest tournaments on the planet.
- Power Incontinence: He may be unnecessarily loud socially, but he actually has excellent control over his Quirk, with only two known exceptions: His birth, which bursted the eardrums of his parents and the hospital staff, and confronting the Doctor, which the boiling rage in his voice cracked his sunglasses.
- Psychotic Smirk: He'll occasionally bust out a frightening smirk◊ with dartboard eyes visible under the shades.
- Rage Breaking Point: There have been vague hints throughout the series of Present Mic's well-hidden ruthlessness and pragmatism, but it's in Chapter 268 when his simmering rage finally explodes against the Doctor — who just openly admitted to experimenting on murdered children like Shirakumo and that his original target fifteen years ago was Aizawa — and he literally knocks the old bastard's teeth and nose in while also manhandling answers out of him.
- Red Oni, Blue Oni: The hot-blooded red to Aizawa's cool-headed blue.
- Sad Clown: He may outwardly appear to be happy-go-lucky and energetic all the time, but between Shirakumo's death and Aizawa's resulting depression, it's clear that Yamada has sometimes used his exuberance to cope with any sadness or difficulty in his life.
- Smarter Than You Look: Although he does not seem like the brightest guy, he has a 5/5 Intelligence stat on the Official Character Book, which is above even Aizawa.
- Tragic Bromance: With Oboro Shirakumo, a close friend and classmate of his and Aizawa's who died during their second year at U.A. While Aizawa became even more detached and cynical, Shirakumo's death led to Yamada attempting to mitigate his friend's grief and melancholy by acting as Aizawa's primary source of friendship and encouragement, no matter the cost.
- Tranquil Fury:
- After arriving at USJ and seeing Aizawa's broken body, Mic is almost eerily calm as he steps forward — not a single joke or smile to be seen — and unleashes a brutal sonic scream straight down on the villains.
- The hospital raid reveals that Mic has been bottling up some serious anger issues over the numerous tragedies that have befallen him and his best friends. When he's given a chance to get his hands on the Doctor largely responsible for all of them, Mic doesn't hesitate to beat the absolute shit out of him.
- True Companions: With Aizawa. They have been through a lot together, including the death of their close friend Shirakumo, Aizawa's resulting depression, and numerous injuries and close calls from hero work, but they're always there for each other and have remained close friends into early adulthood. This becomes especially evident when Kurogiri's revealed to possibly be a Nomu-fied Shirakumo.
- Undying Loyalty: To his childhood friends, Aizawa and Shirakumo. He has steadfastly stuck by Aizawa's side for over fifteen years and is more than willing to defy the Hero Commission if it means that he and Aizawa can finally get some answers about what really happened to Shirakumo.Yamada: [punching Ujiko in the face] That one's for making my friend cry!
- Vitriolic Best Buds: The light novels reveal him to be this with Aizawa. Mic constantly annoys Aizawa by giving him Embarrassing Nicknames, singing and rapping in Aizawa's ears while he's trying to nap, and dragging him into conversations he wants no part in. Aizawa responds to this by placing Mic in choke holds until he shuts up (which usually fails in the long-term, anyways). Despite this, they're the other's closest confidante and are almost always seen hanging out together.
- Vocal Evolution: In the English dub's first season, Sonny Strait made Present Mic sound like a stereotypical DJ. In Season 2, due to Sonny Strait coming down with vocal strain, the role was recast to David Trosko, whose voice is less nasal without compromising how bombastic Mic is supposed to be.
- Weaksauce Weakness: Bugs turn out to be a major weakness for him as he can't blow them away with his Quirk because sound can't travel underground, allowing burrowing bugs to sneak up on him.
- Why Did It Have to Be Snakes?: He's deathly afraid of bugs. This is exploited by Jiro and Koda when they are pitted against him during their final exam.
Hirooki Anakuro — Thirteen
Voiced by: Inuko Inuyama (Japanese), Morgan Berry (English)
Debut: Chapter 12 (Manga), Episode 9 (Anime)
Quirk: Black Hole
A woman in a space suit who is known for working with disaster relief. Nicknamed "Space Hero No. 13", she works as a teacher at U.A. that overlooks the rescue exercises. Her Quirk, "Black Hole", allows her to create black holes with her fingers; said holes can disintegrate matter at the atomic level.
- All-Loving Hero: There's a reason she's the one teaching kids how to use their power for good - she outright believes any power can be used to save lives, and that saving lives is their natural use.
- Ambiguous Gender: While she is referred to as the "gentleman hero", Thirteen's actual gender was unknown for a very long time. Both the manga and anime made it a point to never show Thirteen's body outside of her costume, her costume appearing empty after being torn open by Kurogiri, and her hospitalized body being off screen while the scene focuses on her costume against a wall. The only part of her body that is visible in costume is her thin legs, which doesn't help. The anime doesn't help matters either by giving her a female voice actress in both the original Japanese and English dubs, as it is not uncommon to give male characters female voices to simulate a higher pitched male. In the English dub, she's the only one of the teachers helping out in the final exams who aren't addressed as "Mr." or "Ms."- in Japanese, the "-sensei" honorific is gender neutral. The ULTRA ANALYSIS Character Book eventually confirmed her to be female.
- Ambiguously Human: It's unknown how she looks under that space suit. When she nearly dies due to Kurogiri, the audience only sees the empty part of the suit and nothing more. While it's confirmed there is a body in the suit, as the suit is seen on the side with Thirteen is hospitalized while they lie in bed, her body is obscured by the remains of the suit, making it unknown if she appears human of not. In Chapter 296, a portion of Thirteen's face is finally seen through her cracked helmet. Chapter 322 gives us a more clear shot of her face.
- Amputation Stops Spread: Chapter 296 reveals that she had severed her left arm to prevent Shigaraki's Decay from reaching her entire body.
- Bad Powers, Good People: Through her Quirk, she can create black holes that can disintegrate matter at the atomic level, easily capable of killing people if they're drawn close enough. However, Thirteen's a All-Loving Hero who cares deeply for her students and uses her Quirk exclusively for disaster relief and sometimes the capturing of villains. She also avoids combat because she notes this Quirk is one that can easily kill if harnessed improperly.
- Badass in Distress: Kurogiri critically injures her during the USJ Arc by reflecting the effects of her Quirk back at her through his power, forcing the students to split their attention between protecting Thirteen and fighting off the villains.
- Calling Your Attacks: "BLACK HOLE!!!"
- Cosmic Motifs: Thirteen is nicknamed the "Space Hero". Her costume resembles a space suit, she is named after the Apollo 13 mission, and her Quirk (named "Black Hole") gives her "black hole fingers" that can disintegrate matter at the atomic level. Uraraka, who has a gravity-based Quirk, looks up to Thirteen and partially patterns her hero identity on space as well.
- Dark Is Not Evil: A heroic teacher who has the ability to make black holes.
- Exotic Eye Designs: The brief glimpse we get of her face in Chapter 296 shows that her irises have lines intersecting them that make her eyes resemble black holes, fitting with her Quirk.
- The Faceless: In most of her appearances, we never see any part of her underneath her costume. It's not until Chapter 296 that we get even a glimpse of her, and it takes all the way until Chapter 322 for us to see her face in full.
- Good Is Not Soft: Thirteen unhesitatingly uses her Quirk against Kurogiri when he threatens the students, despite the very real possibility that it could've killed the villain had she gone all-out.
- Hoist by Her Own Petard: Kurogiri used his warp gates to loop Thirteen into one of her own black holes, badly rending her apart. She survived, but she was laid up in the hospital for quite some time.
- Meaningful Name: Her name means "Black Hole" and "Middle Space", both referring to her being a space hero and her Quirk. Her hero name, Thirteen, is a reference to the Apollo 13 mission, which famously went horribly wrong and turned into a disaster that the astronauts barely managed to limp home from.
- Nature Is Not a Toy: A fact that she is all too aware of, given the inherent destructive nature of black holes, and she takes great care to maintain control over her powers so as to not kill anyone or cause even more damage.
- Power of the Void: Uses her black holes for clean up during rescue missions, but mentions that she has to keep control over it so that it doesn't kill the people she's trying to rescue. This is because her black holes pretty much disintegrate everything it sucks to a molecular level.
- Powered Armor: Her spacesuit is designed to keep her black holes under control. For example, her fingers have little caps she can flip up and use the gravity of the black holes she produces inside to vacuum-clean debris and pull things toward her slowly.
- Samus Is a Girl: Thirteen's face is hidden until Chapter 296, where her helmet has been partially broken and reveals a an unmistakable female face. Until then, no one could confirm the gender of Thirteen by her voice, which was ambiguously feminine.
- Unrealistic Black Hole: Her Quirk can essentially be described as black hole fingers.
- Unskilled, but Strong: Kurogiri pretty much says this; being that Thirteen's Quirk is very dangerous, but is at a disadvantage without experience fighting villains.
Ken Ishiyama — Cementoss
Voiced by: Kenta Okuma (Japanese), Chris Rager (English), Carlos Márquez (Latin American Spanish/TV series)
Debut: Chapter 21 (Manga), Episode 13 (Anime)
A being who can control any form of cement through his Quirk, "Cement". Also a Modern Literature teacher.
- Ambiguously Human: There's a reason he's described as a "being".
- Badass Baritone: In Japanese, he's cast with a pretty deep voice.
- Badass Teacher: He's the Modern Literature teacher.
- Barrier Warrior: A more blunt example than most, one of the most common uses of his Quirk is to raise barriers from cement.
- Curb-Stomp Battle: Gives an absolutely one-sided one to Satou and Kirishima during the Final Exams Arc.
- Dishing Out Dirt: Anything with concrete he can control.
- Home Field Advantage: Very powerful in urban settings thanks to the abundance of concrete.
- Impaled with Extreme Prejudice: After his fight with Geten in the Liberation Army War Arc, he's not looking so good with several large spikes of ice imbedded in his body, about the only reason to say he's not dead is because he's not on the list of casualties in Chapter 296.
- Irony: Despite being blocky, official material states that he likes round things.
- Logical Weakness: He doesn't fare well in areas that have no concrete for him to manipulate.
- Meaningful Name: His name means "stiff, firm", like cement, referencing to his Quirk. His last name contains the kanji for "stone" and "mountain".
- Mundane Utility: He uses his cement powers to provide the ring for the Sports Festival.
- The Knights Who Say "Squee!": He's a hero who's a big fan of All Might.
- Wake-Up Call Boss: Minor example. He's the first teacher faced during the final exams in the anime (the manga has the matches occur at the same time), and his sound defeat of Kirishima and Sato demonstrates that even if the teachers are going easy on the students, they're not playing to lose.
Nemuri Kayama — Midnight
Voiced by: Akeno Watanabe (Japanese), Elizabeth Maxwell (English), Giset Blanco (Latin American Spanish/TV series)
Debut: Chapter 12 (Manga), Episode 9 (Anime)
An S&M-themed pro heroine. She refs the the U.A. Sports Festival and teaches Modern Hero Art History. Her Quirk is "Somnambulist", which allows her to release a sleep-inducing fragrance from her body.
- Action Girl: As a professional hero and a member of U.A.'s staff, Midnight is a very qualified hero whose entire job is to kick villain butt and protect the peace.
- Adaptation Dye-Job: Her flesh-colored bodysuit is changed into white for the anime.
- Anime Hair: While it isn't Rapunzel Hair, it's still very long and is styled akin to a conifer tree. She had shorter hair when she was young.
- Ascended Extra: Midnight doesn't have a big role in the main series, but in the prequel My Hero Academia: Vigilantes, she is one of the returning characters with the biggest amount of screentime, alongside Aizawa.
- Badass Teacher: She teaches Modern Hero Art History, which entails aesthetic features of hero work, and can easily incapacitate enemies with her Quirk. She was also once depicted teaching what looked to be trigonometry.
- Beauty Is Never Tarnished: Subverted. During the heroes' battle with the Paranormal Liberation Front, Midnight tries to knock out Gigantomachia with her Quirk, only to be intercepted by a massive chunk of concrete thrown by Mr. Compress. She falls to the forest floor bloodied and badly injured with her hair disheveled and her mask in disarray. She is later confirmed to have died in her fight with a villain, the manga never shows her body, but an earlier scene of her face down in a pool of blood confirms it wasn't pretty.
- Beauty Mark: A small one dots her left cheek just below the eye.
- Berserk Button: She has two:
- Being interrupted while she's talking.
- Making fun of her age.
- Bunny-Ears Lawyer: Aside her dominatrix and Double Entendre tendencies, she genuinely wants to help students and encourages their efforts in becoming heroes. She believes she can stop teenagers from turning into criminals by being a teacher and sometimes supervises their Quirk training.
- Chained by Fashion: Has two handcuffs on her wrists as part of her S&M motif.
- Christmas Cake: In an omake, Mt. Lady accuses her of being this by making a catty comment about her age.note
- Cool Teacher: Midnight tends to be very supportive of the students, as demonstrated with Class 1-A's naming assignments. She praises almost all the hero names, the exceptions being Ashido and Bakugo's.
- Cuteness Proximity: When she gets to hold the Cute Kitten Aizawa was taking care of in Vigilantes, she just melts into a wavy-mouthed, Baby Talking softie who promptly names and adopts the little guy:Midnight: Awww, so fwuffy.♡
- Dead-Hand Shot: The last that's seen of her in Chapter 296.
- Does This Remind You of Anything?: To go with her S&M theme, her Quirk being Knockout Gas is reminiscent of Chloroform.
- Domino Mask: She wears a red one as part of her hero costume.
- Double Entendre: A good chunk of what comes out of her mouth is this. Sometimes she even does it subconsciously, like her explanation about wanting to be a teacher to help students work through their teenage angst in Vigilantes:Midnight: Fufu... isn't it just wonderful? The blood, sweat and tears of youth? And various other... bodily fluids.
Aizawa: Bodily fluids?
Midnight: (while making a very suggestive squeezing hand gesture) Do I have to spell it out for you? There's plenty of kids out there who get stricken by puberty and go on to become villains and criminals because they weren't able to "let it all out"! And that's where I come in! I'll squeeze them all dry!
- Dressed Like a Dominatrix: Despite being a heroine, she wears a black breastless leotard over a white bodysuit to contain her natural sleeping gas powers, along with thigh-high stockings and black knee boots. She also uses a whip as a weapon. It's later revealed that her original hero costume, dubbed "Birthday Suit Style" in Vigilantes, was even worse, effectively being a trench coat and strategically-placed pouches and belts. This directly led to the "Hero Costume Skin Exposure Limitation Act", which outlawed such outfits. Her second hero costume was a braless corset leotard with a weapon harness that just happened to cover around a fifth of her breasts.
- Duel Boss: The final exams are supposed to be two students against one teacher. However, Midnight knocks out Sero in three seconds flat, forcing Mineta to face her by himself.
- Exact Words: Unintentionally does this in Vigilantes. When she was still attending U.A., she claimed that she and her "Birthday Suit Style" hero costume would "have all of Japan thinking differently" about Stripperiffic hero costumes in one year's time. She was right because one year later, the government pushed forward the "Hero Costume Skin Exposure Limitation Act":Midnight: (embarrassed) Too much, too soon?
- Fangirl: Of her students, since they represent the pinnacle of youth. She gets excited watching them fight.
- Gargle Blaster: Her preference for heavily alcoholic beverages leads her to mix up the nastiest cocktails possible when she's feeling tipsy. Worse still, she forces others to try them, and one serving was enough for Mic to claim he saw the other side and his ancestors waiting to greet him.
- Good Bad Girl: She's always been very flirty and shameless woman who has zero qualms about her behavior, but is a good and honest woman at heart.
- Hard-Drinking Party Girl: She's this on her days off. According to School Briefs, she prefers drinks that can put a fire in her gut, ordering tequila as her first drink at a teacher's night out. Unfortunately, she also has a habit of mixing up gargle blasters that she forces other people to try when she's drunk.
- Hidden Depths:
- Vigilantes reveals that she wanted to become a teacher to help the youth since she believes many criminals and villains are born out of teenagers who were too repressed to properly express themselves when they were young. It's also implied that she likes to act as a counselor for the students.
- In an omake, she goes into a detailed and logical explanation for the skimpy clothing, in that due to the nature of some Quirks, clothing hinders them and the sexiness for some became a necessity. Unfortunately, Mt. Lady provokes her before she can finish.
- Hot-Blooded: She loves the passionate youth, readily agreeing to bend the rules of the U.A. Sports Festival when things are done out of passion, such as letting Ojiro and Shoda drop out of the combat portion when they feel their pride won't let them compete without properly earning the spots or letting Iida use Mei's inventions. Additionally, she fangirls over the manly Defeat Means Friendship that happened during Kirishima and Tetsutetsu's fight and gets pumped up whenever it seems that a fight is about to reach its peak.
- Hot for Student: A few jokes are made about her interest in youth being actually an interest in her students.
- Hot Teacher: The 18+ Heroine has earned her name and reputation as a sexy heroine and is a teacher at U.A. In Vigilantes, she more of the traditional pedagogical hottie, as she dresses in secretarial clothes.
- Killed Off for Real: Even though Midnight is a challenging opponent, she suffers critical injuries in the battle against the Parnormal Liberation Front, and the sheer number of villains overwhelms her and ultimately kills her.
- Killed Offscreen: She's last seen in Chapter 278 after receiving a sneak attack from Mr. Compress that leaves her heavily injured and with a group of villains running to attack her. For eighteen chapters, her status remained unknown, though Yaoyorozu and Ashido keep assuring everyone she is fine. Then comes Chapter 296 when the U.A. students find her dead body, the chapter fully confirms her death by listing her first among the hero casualties of the Liberation Army War.
- Knockout Gas: Her Quirk. It releases this from her skin, which is why so much of it is covered.
- Male Gaze: Due to her revealing hero costume and general bearing, she's the subject of much male attention when she walks around.
- Marshmallow Hell: In Vigilantes, this is how she nullifies villains affected by her Quirk with a hug to her chest.
- Meaningful Name: Her real name contains the kanji for "fragrance" and "sleep". Her hero name actually has two different meanings, referring to midnight as in bedtime, and midnight as in her after dark nature as a heroine catering to a more adult crowd.
- Mentor Occupational Hazard: As a teacher at U.A. it was her job to mold and train young heroes. Vigilantes revealed it was something she greatly enjoyed. One of her last acts was encouraging her students to continue to work at becoming great heroes and to keep fighting. She was especially impressed by Yaoyorozu's ability to lead and saw great potential in her. Sadly, she dies during the Liberation Army War.
- A Million Is a Statistic: Very much Played for Drama. Despite being a major, world famous hero and part of the main trio of the U.A. staff, her death is treated in story and out as essentially an afterthought, highlighting that she's just one of the countless faceless Heroes and Villains who fell during the War.
- Ms. Fanservice:
- Just look at her hero costume. Even All Might is careful not to look at her when she is standing close to him.
- Subverted in a Smash!! comic where she is supposed to be the teacher for a pool exercise for Class 1-A. Mineta and Kaminari believe they'll get to see her in some nice bikini, but she is wearing layers of unflattering clothes and hat to protect her skin from sun damage.
- Nude-Colored Clothes: She wears tights all over her body as a form of censorship, which is more obvious in the anime, where they are white instead of skin color.
- Pink Is Erotic: Her Quirk emits a pink aroma that puts her targets to sleep. Her outfit is supposed to invoke imagery of a dominatrix and her aroma is comparable to the effects of a date rape drug.
- Reasonable Authority Figure: In Vigilantes, she's able to see that Pop is not in her right mind during the bomber incident due to their shared history, harmlessly knocking her out after Koichi brings Pop to her. She also allows Koichi and the others to escape and lies to Endeavor to keep them out of danger.
- Required Secondary Powers: She's immune to her own sleep-inducing mist.
- Sacrificial Lion: Midnight is part of the team of three of the U.A. teachers, proved herself useful and crafty, and she had a bigger role in the Vigilantes spin-off. However, her sudden death during the Paranormal Liberation War Arc took Aizawa and the Class 1-A students by surprise, with Kirishima, Ashido and Yaoyorozu mourning over her body.
- Sadist: Watching someone runs away in terror gets her heart throbbing.
- Sadist Teacher: Zigzagged. While she does have sadistic tendencies, she genuinely wants to help students and guide them towards their goals.
- Sempai/Kohai: Vigilantes shows that she was a year above Eraserhead and Present Mic while they were all students at U.A. Since then, she's been something of a Cool Big Sis to them both, getting Eraserhead his student internship as well as his eventual teaching position a decade later.
- Shameless Fanservice Girl: She publicly advertises herself as "R-rated":
- Has no problem wearing BDSM gear during televised events or in class. In fact, her first hero costume was so revealing that a law was passed in response, requiring hero costumes to cover a certain amount of skin.
- In Chapter 43 of Vigilantes, she wears a corset that shows off her ample cleavage, panties and dark leggings. Thankfully, her Quirk knocks out all the guys.
- Chapter 60 of Vigilantes also reveals she was a straight-up exhibitionist as a U.A. student, wearing nothing more than a trench coat and strategically-placed pouches and belts. She even brags about her "costume" being the pinnacle of form and function.
- Statuesque Stunner: Even without the heels, she's still 175 cm tall.
- Stripperiffic: Her hero costume invokes this. In order to use her Quirk, she has to have her skin exposed. This means that exposing as much skin as possible is necessary for her to be effective. Her original hero costume from when she was first starting out, fittingly called "Birthday Suit Style", was an actual example, so much so that it provoked actual legislation concerning skimpy hero costumes.
- Superhero Sobriquets: "18+ Only Heroine".
- Tempting Fate: As mentioned under Exact Words, when she confidently predicted that people would become more accepting of risqué hero costumes, the opposite ended up happening.
- Villain Ball: During the Final Exams Arc, Midnight plays the "villain role" for Sero and Mineta. Had she stayed at the escape gate, she could've run down the clock, which would have caused them to fail their final exam. However, her sadistic nature led to her pursuing Mineta, only to get pinned down by his Quirk far away from the gate. To her credit though, she was going easy on them and even lampshadeds this trope, making it justified why she wouldn't be so willing to knock Mineta out.
- Weak, but Skilled: While her power is a 2/5 as stated by the Character Book, she more than makes up for it with an outstanding 5/5 in Technique. Her Quirk is not good for attacking, but it is strategically invaluable and has shown no apparent weaknesses yet.
- Whip It Good: As expected of an S&M-themed heroine, she has a whip.
Voiced by: Tōru Nara (Japanese), David Wald (English), Rómulo Bernal (Latin American Spanish/TV series)
Debut: Chapter 20 (Manga), Episode 13 (Anime)
A sharpshooting hero. He possesses the Quirk "Homing", which allows him to control the trajectory of his bullets at a range of up to 600 meters.
- Accidental Pervert: See Thanks for the Mammary below. To his credit, he frantically tries to apologize for it as soon as he realizes what happened.
- Big Damn Heroes: Announces the presence of the arriving pro heroes to the invading villains of the training grounds by hitting a good number of them with his aiming skills. He even nearly severely wounds Shigaraki before Black Mist warps him out of there.
- Brought to You by the Letter "S": His hat has a big "S" on it, referring to his name.
- Cool Mask: Wears a stylish gas mask as part of his costume.
- Good Is Not Soft: He's a genuine hero, but his weapon and powers revolve around shooting people. Downplayed, however, as he is very good at aiming to incapacitate, not kill.
- The Gunslinger: His Weapon of Choice is a gun, fitting his cowboy theme.
- Hand Cannon: Wields an oversized, double-cylindered pistol.
- Homing Projectile: His Quirk, aptly called "Homing", lets him control the trajectories of his bullets to better hit their targets.
- Improbable Aiming Skills: Justified by his Quirk, Homing, which allows him to alter the trajectory of his bullets, but he is still doing so while they're nothing more than a spec in his field of vision or while they're behind obstacles in such a way that he barely has any sight on his targets at all.
- Out of Focus: Snipe is often shown as one of the teachers part of Nezu's inner circle and discussing the school's plot-important decisions alongside Midnight, Present Mic, Aizawa, All Might, and Vlad King. In comparison to them, he receives the least amount of attention and very rarely interacts with the students. One of his noticeable scenes is technically a flashback to an interview where he's talking about another Hero who's better than him who just so happens to be in the present hunting Deku down for All For One.
- Overshadowed by Awesome: To Lady Nagant, who he freely admits is his better thanks to her superior range (3km to his 600m), superior firepower (packing a sniper rifle with Abnormal Ammo she generates on the fly while he uses pistols with conventional ammo), and the fact that while he needs his Quirk for his Improbable Aiming Skills, hers are all-natural.
- Shout-Out: A cowboy-themed sharpshooter with the power to control the trajectory of his bullets, similar to Hol Horse from JoJo's Bizarre Adventure.
- Superhero Packing Heat: As expected of a hero sharpshooter. Unlike most examples, however, he seems to near exclusively aim for incapacitating, nonlethal shots.
- Talking Is a Free Action: Averts this when he shoots Shigaraki mid-monologue. If Kurogiri hadn't been there to bail him out, Shigaraki would have been left helpless and captured.
- Thanks for the Mammary: Accidentally touches Hagakure's breasts with his elbow after he's beaten in the end of the final exam.
- Too Many Belts: Wears at least three or four of them under his poncho. However, each one serves a purpose, securing his holsters and body armor in place.
- Transplant: He originally came from the My Hero one-shot.
- Weak, but Skilled: According to the statbook, he's average in everything but technique, which is ranked S.
Voiced by: Masakazu Nishida (Japanese), Mike McFarland (English)
Debut: Chapter 20 (Manga), Episode 4 (Anime)
A hero with a ghostly theme and U.A.'s Mathematics teacher. His Quirk, "Clones", allows him to create copies of himself out of ectoplasm coming out of his mouth.
- Attack of the 50-Foot Whatever: He can create a huge copy of himself.
- Badass Baritone: He speaks with an unnaturally deep, chorused voice that only adds to his already menacing appearance.
- Badass Longcoat: He wears a heavy trenchcoat in costume and lets the collar stick up like the mantle of a cape. This is not to be confused with a Coat Cape where someone drapes their coat on their shoulders, because Ectoplasm wears his over his entire body.
- Badass Teacher: Evidently, he's a math teacher.
- Dark Is Not Evil: Very creepy-looking, but he's a hero and a teacher.
- Doppelgänger Attack: How he uses the copies he makes — multiple copies can attack the enemy at once, but they only take a hit or two to take down.
- Extremity Extremist: Exclusively uses his legs during combat, leaving his arms tucked underneath his trenchcoat.
- Handicapped Badass: He lost his leg in a past battle against a villain, and now uses two prostheses: a normal one for everyday civilian life and a lightweight one for heroism.
- Hidden Depths: He apparently really likes karaoke.
- Mystical High Collar: The lapels of his coat are very flared and upturned, and his powers stem from what is deemed ectoplasm, which is usually seen as the supernatural slime of ghosts.
- Nightmare Face: He looks scary even without his mask. That Slasher Smile isn't part of his hero costume, it's just what his mouth looks like normally.
- Self-Duplication: His Quirk. He's limited to creating around 30 (36 after a heartfelt karaoke session) clones of himself at once, but he can move and dissolve these clones at will. He can also create a big copy, but at the expense of not being able to create more clones while the big one is active.
- Stealth Pun: Ectoplasm teaches math. He's the multiplying teacher.
- Soul Power: Can manipulate ectoplasm to form clones of himself.
- Training Dummy: His clones make great punching bags for students trying to get a better handle on their Quirks.
- Whole Costume Reference:
- Of Spawn, particularly of his later redesign which included similar teeth to Ectoplasm's and their Mystical High Collar (though Spawn's is part of his red cape while Ectoplasm's is white), who is a genuinely undead '90s Anti-Hero.
- His helmet is extremely similar to the one wore by one of the members of the band Daft Punk. He is even stated to like karaoke as well.

- Cloudcuckoolander's Minder: He attempts to play this to the ever energetic Hatsume. However, she spends a good amount of time not paying attention to him or even outright ignoring his warnings.
- The Faceless: Only ever seen with his mechanical headgear on.
- Gadgeteer Genius: He is the resident tech teacher, able to help in designing and upgrading hero costumes and gear. He is also Hatsume's teacher. Oddly enough, though, he only has 2/5 Intelligence.
- Powered Armor: He wears a suit of armor.
- Shout-Out: To the Power Loader, the powerful yellow exosuit from Alien.
- Slasher Smile: It seems to be his default expression.
- Tunnel King: His fingers are tipped with claws that allow him to dig through the ground. Iida and Ojiro's final exam is set in a large field, which Power Loader is continuously destabilizing by digging.

Other U.A. Staff
Voiced by: Yasuhiro Takato (Japanese), Jerry Jewell (English), Xavier Coronel (Latin American Spanish/TV series)
Debut: Chapter 12 (Manga), Episode 4 (Anime)
Quirk: High Spec
The principal of U.A. High School. His appearance resembles some sort of furry animal. His character sheet reveals that his real name is Nezu, a play on the word for "rat" in Japanese, and that he's an extremely rare case of a Quirk appearing in an animal.
His Quirk is "High Spec", which grants him Super Intelligence.
- Animal Superheroes: Naturally. Being a hero is one of the requirements for one to become a teacher at U.A.
- Anthropomorphic Transformation: Actually an animal who was morphed to have an anthropomorphic body by his Quirk.
- Big Good: A formal example due to his position as principal of U.A.
- Being Tortured Makes You Evil: Downplayed. While he chose to use his intelligence for heroic purposes despite the experiments that were performed on him, that doesn't mean that he won't enjoy the occasional opportunity to make humans squirm.
- Cartoon Creature: Lampshaded in his very introduction. He is supposedly a mouse, but that wouldn't explain his size.
- Character Filibuster: Nezu tends to ramble incessantly whenever he addresses the student body and faculty. All Might lampshades it best:All Might: With the principal, if I let him go on, it'll never end...
- Curb-Stomp Battle: He's one of two teachers who wins their final exam fight, absolutely shredding Ashido and Kaminari, boxing them in by strategically knocking down their surroundings with a wrecking ball. Even when he purposefully leaves them a way out, they can't find it and lose.
- Disaster Dominoes: Invoked. With his vast intelligence, Nezu can perfectly calculate where to strike with his wrecking ball during the final exam to create the exact chain of destruction he needs to rout his targets.
- Everyone Calls Him "Barkeep": Actually has a real name, but is frequently referred to as the school's principal.
- Evil Laugh: When showing his "darker" side.
- Fiction 500: In Chapter 323, Nezu reveals that hes completely revamped U.As security systems to a ridiculous degree, to the point that the entire campus is actually mobile, and that the individual evacuation shelters can be shuttled off via underground tunnels to completely different parts of the country, while protected by dozens of layers of armor plating. The kicker Nezu paid for this entire system out of his own pocket. Endeavor explains that Nezus contributions to Quirk education are so pervasive that its made him massive amounts of money.
- Fully Dressed Cartoon Animal: He's some kind of animal, but wears clothes just like humans.
- Intellectual Animal: Thanks to his Quirk, he's actually smarter than any human.
- Large and in Charge: Inverted. He is the smallest teacher in U.A. and its principal.
- Meaningful Name: "Nezu" is a pun on the Japanese word for "rat", "nezumi". That said, whether it's really a Meaningful Name or a Non-Indicative Name depends on whether Nezu is a rodent or some other animal. At any rate, it reflects his past as a lab rat, be it literal or figurative.
- Putting the "Pal" in Principal: Nezu is an affable creature who genuinely prioritizes the students' growth and well-being. He does have a "darker side" that is played for laughs, though.
- Readings Are Off the Scale: Not quite as much as All Might, but his Intelligence at least breaks the official rating scale at 6/5. Appropriate, since Super Intelligence is his power.
- Reasonable Authority Figure: So far, he appears to be a nice, smart and trustworthy person, enough to be one of the few people that knows about the true nature of All Might's One For All.
- Rodents of Unusual Size: Part of the reason he gives off Viewer Species Confusion In-Universe is that he is too big to be a mouse.
- Rugged Scar: Has one on his right eye. It's almost undeniable that he got it from the many abuses inflicted on him through experimentation.
- Secret Keeper: He's one of the handful people who know the true nature of One For All, along with Recovery Girl, Midoriya, and Gran Torino.
- Shoulder Teammate: He is occasionally seen sitting on his colleagues' shoulders.
- Smart People Wear Glasses: Nezu doesn't wear glasses but his Quirk's name, High Spec, evokes this.
- Spell My Name with an "S": His name is often spelled as "Nedzu" by fans.
- The Strategist: As Kaminari and Ashido learn, Nezu is always many steps ahead of his opponents and it takes a lot of brainpower to outwit him, something they sadly lack going into their final exam. Nezu schools them harder than any other teacher, proving why he's the principal of U.A.
- Super Intelligence: His Quirk, and its not that he is an animal with human level intelligence, his Quirk has made him the smartest person on the planet.
- They Would Cut You Up: As an animal with a Quirk, he was experimented on when he was first discovered.
- Token Non-Human: Even taking into account the various mutant Quirks, Nezu is actually not a human, he's an animal who's among the very few who have Quirks, making him this not only for U.A.'s staff, but also amidst heroes as a whole.
- Uplifted Animal: He's an animal who got Super Intelligence because of his Quirk.
- Viewer Species Confusion: His species is indeterminate. As he himself says, he might be a mouse or a dog or a bear. This is lampshaded to the point that he's the trope image. However, it has been lightly implied that he is a mouse later in the plot.
- World's Smartest Man: Nezu, whose Quirk, High Spec, does not merely give him Super Intelligence, but makes him smarter than any human on Earth, to the point that he's easily able to calculate the precise angles and velocities required to perform Disaster Dominoes with a wrecking ball. He's also in charge of the most esteemed hero school in Japan and his official ratings give him a 6/5 in intelligence.
Chiyo Shuzenji — Recovery Girl
Voiced by: Etsuko Kozakura (Japanese), Juli Erickson (English, Season 1), Luci Christian (English, Season 2 onward), Patricia Azan (Latin American Spanish/TV series)
Debut: Chapter 4 (Manga), Episode 4 (Anime)
The school's resident nurse. Her Quirk, "Heal", speeds up the recovery of injuries of her patients.
- Fan Disservice: Any one of the kisses she gives to heal wounds qualifies. Both the manga and the anime portray the first instance she does this as revolting enough to warrant an action splash graphic.
- Good Is Not Soft: While Recovery Girl is a kindhearted person, if someone engages in Self-Harm through abuse of their Quirk, she'll eventually refuse to treat them unless it means they'll die. Midoriya and, by extension, All Might find out about this after the former's defeat in the U.A. Sports Festival, thanks in no small part to his recklessness in his match against Todoroki.
- Healing Hands: Played with, as her power allows her to magnify someone's own regenerative process.
- Healing Magic Is the Hardest: Her Quirk technically doesn't heal injuries outright, but rather speeds up the patient's natural healing process to repair any damage. As a result, those healed by her are exhausted after receiving the benefits, and her powers can become ineffective after too many repeated uses due to the body using up its energy reserves, as Midoriya finds out the hard way.
- Intimate Healing: Her Quirk manifests through smooches.
- Meaningful Name: Her name contains the characters for "discipline", "provide", "healing" and "virtuous". All of which can connect to her personality and Quirk. Her first name, "Chiyo," sounds like chiyu (治癒), meaning "healing", which also explains her Quirk working via a Magic Kiss, or chuu. The "Shuzen" in her last name is also homophonous with "repair" (修繕).
- The Medic: She's the school nurse with the power to heal. You have to expect she's this.
- Miniature Senior Citizens: One of the oldest members of the school and naturally short in stature.
- Non-Action Guy: Unlike the rest of U.A.'s staff, who are still active heroes when the need arises, Recovery Girl stays in her office and treats the wounded even during times of crisis. Considering she's an elderly woman with a Quirk that has no apparent combat value, it makes sense.
- Non-Indicative Name: "The Youthful Heroine: Recovery Girl" is a senior citizen, not a young lady as the name suggests.
- Rule of Symbolism: Befitting a healing-themed heroine, both her hairpin and cane are styled after a syringe.
- Secret Keeper: She is one of the few people who knows everything about All Might's Quirk. This is because she was one of the people who helped him through his long and troubled recovery after All For One brutally maimed him, and not even her power was enough to completely fix him back up, because some of his organs were outright gone and she can't recreate lost body parts - that's a totally different Quirk entirely.
- Superhero Sobriquets: "The Youthful Heroine".
- Team Mom: As the oldest member of the faculty at U.A., she seems to have a tendency of behaving very motherly both towards her patients and towards All Might sometimes, reprimanding his bad behavior in the manner of a mother talking to her child.
- What the Hell, Hero?:
- Delivers one to All Might when Midoriya's drive to meet his expectations results in three limbs being so broken that they can't be healed with her Quirk the normal way, requiring surgery.
- Does this again after both of Midoriya's matches in the U.A. Sports Festival, as he had broken his fingers on both occassions. She even went as far as to hit All Might to emphasize her point. Following Midoriya's defeat against Shoto Todoroki, she outright refuses to heal him going forward because he showed little regard for his own health throughout the event. Perhaps the exception to this involved the aftermath of his class's battle against the League of Villain's Vanguard Action Squad and the Shie Hassaikai.
- Does it once again after the training session in which Midoriya and Bakugo are brutally beaten by All Might's overwhelming strength, saying that Midoriya's lower back was within a hair's breadth of snapping beyond all recovery.

Debut: Chapter 7 (Manga), Episode 6 (Anime)
The school's chef.
- The Faceless: Wears a breathing mask and a large chef's hat over his head.
- Meaningful Name: His hero name references what his job is.
- Supreme Chef: Implied due to how many students are seen eating in the Grand Mess Hall, as well as Uraraka stating that she likes the school's food. While brainstorming for the School Festival, Class 1-A decides against doing anything food-related since there's no way they can rival his cooking.
- Trademark Favorite Food: He likes white rice.
Ryo Inui — Hound Dog
Voiced by: Eiji Hanawa (Japanese), Zach Bolton (English), Rubén Moya (Latin American Spanish/TV series)
Debut: Chapter 20 (Manga), Episode 13 (Anime)
The school's Lifestyle Guidance Counselor who sometimes falls victim to his canine nature.
- Angrish: Starts barking and growling when he's worked up. Since he's introduced immediately after Bakugo and Midoriya's fight, he's so mad that he can barely get more than three actual words out.
- Animal-Themed Superbeing: He's a dog-themed hero, which is made pretty obvious by his hero name. He also greatly resembles a dog and tends to revert to canine behavior when he's upset.
- Bunny-Ears Lawyer: He has a tendency to devolve into fits of angry snapping and barking and even physically attacking people in the process, but he is also a very caring guidance counselor who wishes to help students as best he can.
- Face of a Thug: His face is a permanent furious glower even without the mask, and his eyes are lizard-like slits.
- Hidden Heart of Gold: Like Gang Orca, he's stern and really intense when he gets worked up, but he's good with kids and cares deeply for U.A.'s students.
- Meaningful Name: His family name contains the kanji for "dog", and his given name means "hunting", with the kanji used for it also being part for the Japanese word for "hound" (ryoken).
- The Nose Knows: As could be expected of a person with the abilities of a dog, he's got an incredibly keen sense of smell, which was once used to have him act as a "guard dog" when the school beefed up security for the school festival.
- The Unintelligible: Not all the time, but when he starts spewing angrish, it's hard for him to get his point across. He can talk just fine when he's relatively calm, though.
Debut: Chapter 3 (Manga), Episode 3 (Anime)
U.A. employs several types of semi-intelligent machinery to assist with teaching. Notably, there's Villain Bots, combat testing machines designed to simulate real-life D rank villains during the entrance exam, Conveyor Bots, tiny machines that assist with the transportation of the injured, and Camera Bots, that record school events and monitor the school.
- A.I. Is a Crapshoot:
- Played Straight in the Vigilantes bonus Chapter 6+ Beta, where a rogue Executor rampages in a city and is taken down by All Might.
- Invoked during training sessions, such as the one showcased in Chapter 256. The villain bots boast about being "the skynet of this world", but it's just a way to make the training session more lively.
- Benevolent A.I.: While it's unclear exactly how intelligent the machines are, they are intelligent enough to crack wise and snark at humans without actually showing any vitriol toward them.
- Deadpan Snarker: They take plenty of jabs at their human creators, such as the Conveyor Bots noting how fragile humans are, or a Camera Bot giving Aizawa a hard time when it catches Midoriya and Bakugo fighting.
- In the manga, during Present Mic explanation of the entrance exam, the Villain Bots are represented by a Koopa, a Goomba, a Piranha Plant, and a Thwomp, all enemies from Super Mario Bros. The anime replaces them with silhouettes of the robots.
- The different types of Villain Bots are named after classes of starships from Star Wars: one-pointers are Victory, two-pointers are Venator, three-pointers are Imperial, and zero-pointers are Executor.

A young girl whom Overhaul claimed to be his daughter. She was held captive by the Shie Hassaikai, as her Quirk was central to their plans, before being rescued by the heroes. As of the U.A. Cultural Festival Arc, she's been taken into custody by U.A. and is taken care of by the staff.
- Abusive Parents:
- Eri's real mother didn't want anything to do with her after her Quirk accidentally erased her father from existence. This prompted Eri's mother to disown her and leave her in the care of Eri's grandfather, the former Boss of the Shie Hassaikai, after telling him that her own daughter is cursed.
- Overhaul pretends to be her father just for the sake of manipulating her more easily. He makes her think she's a weapon being used to and born to destroy people. He drains her blood to use its properties to make Quirk nullifying bullets. When she runs out of blood to give, he uses his Quirk to break her down and reset her back to normal. Given what's seen of people who have been broken down, it can't have been a nice experience at all and Eri has clearly been traumatized by these experiences. Mirio is completely horrified when he learns about it.
- Adaptation Dye-Job: A similar downplayed case to Shigaraki, colored pages show she has pure-white hair in the manga, which is changed to a blueish-white tint in the anime.
- Adult Fear: Eri is a prisoner of her adoptive uncle, who controls her by threatening to kill his enemies and even her, with the power to immediately undo it.
- Badass and Child Duo: Has this dynamic with both Mirio and Midoriya when defending her from Overhaul. Becomes especially apparent with Midoriya when he straps her to his back to take down Overhaul for good, her "rewind" Quirk able to undo the damage he gains from One For All 100%, thus allowing him to go all out against Overhaul.
- Back from the Dead: According to Overhaul, she'll be all right if he "destroys" her so long as he "repairs" her immediately — and it's happened before. The prospect of hearing this makes Mirio sick.
- Bandage Babe: While under the control of the Hassaikai, she has bandages wrapped around both arms and legs, which combined with her general Broken Bird demeanor is designed to elicit the desire to rescue her and keep her safe from both the audience and the characters. She avoids the usual fetishistic implications of this, though, both because she's 6, way too young to be viewed that way, and because she wears an oversized pale-tawny dress which combines with the bandages to keep her modesty completely safe at all times.
- Barefoot Captives: She goes barefoot while living in the care of the Shie Hassaikai. This is no longer the case after she is rescued and taken into the care of U.A. She is given cleaner and prettier clothing, including some nice shoes.
- Blessed with Suck: Eri can rewind living beings to a previous state. A bout of Power Incontinence led to her accidentally erasing her father from existence, which prompted her horrified mother to disown her. Her Quirk then led Overhaul to take an interest in her as a source of Quirk erasing drug, which he extracted from her body in an excruciatingly painful process.
- Broken Bird: Eri has been abused so much in the hands of the Hassaikai and Overhaul that she has actually resigned herself to bear the suffering out of sheer hopelessness. When she's going to be harmed because Overhaul will fix any damage done to her and is throwing her under the bus, Eri grits her teeth and waits for the inevitable. She's in a near-catatonic state when she finally meets Midoriya out of fear and pain, and by the time Midoriya and Mirio meet her in the hospital after the raid, the overall trauma has caused her to forget how to smile.
- Broken Tears: In the middle of being rescued, Eri starts to break down in tears when she sees that the rescue operation is only managing to get heroes brutalized left and right, and they get worse when Overhaul gives a Breaking Speech saying that it was selfish of them to try and rescue her because Eri is unwanted and trying to save her will just result in more pain for her and everyone involved.
- Cheerful Child: Though she's introduced as being deeply traumatized by Overhaul's abuse, being rescued and U.A. taking her into their custody has improved her mental state and she's well on her way to becoming more cheerful. Class 1-A's performance makes her grin for the first time in the series, which clearly delights Mirio, and she excitedly recaps it to Midoriya afterwards. Later, she giddily consumes a candy apple Midoriya made for her.
- Color-Coded Wizardry: When her Quirk is used, it manifests as glowing yellow streams of energy.
- Combination Attack: Eri continually heals Midoriya's wounds to bypass One For All's drawback to pull out 100% of its power against Overhaul in the final battle of the Internship Arc, while Midoriya continuously destroys his own body to keep her from accidentally erasing him.
- Damsel in Distress: She's a young defenseless girl in the Hassaikai's custody who are using her cells as the basis for a drug-dealing operation. Saving her and taking down the Hassaikai are the objectives of the Internship Arc.
- Death by De-aging: Her Quirk lets her "rewind" living things to a previous state, including to the state in which they never existed. She accidentally did this to her father when her Quirk first awakened, and the bullets that the Shie Hassaikai are producing work by rewinding the people they shoot to a state from before humanity first developed Quirks.
- Devolution Device: Humans with Quirks are considered the next stage of evolution. Eri's Quirk is a Semantic Superpower revolving around the term "rewind", which Overhaul exploits to create bullets that De-Power those with Quirks, turning them into normal humans. He also suggests that she can turn a human into an apelike creature with some effort.
- Dispel Magic: She uses her Quirk to cancel Overhaul's fusion with Nemoto, separating them into their normal selves.
- The Dog Bites Back: As Overhaul is about to escape with her during his fight with Midoriya, Eri, reminded of the heroic sacrifices of those who came to save her, uses her Quirk to undo Overhaul's One-Winged Angel and free herself. Eri eventually teams up with Midoriya and uses her Quirk to erase the drawbacks of fighting at One For All at 100%, allowing the two of them to defeat Overhaul once and for all.
- Everyone's Baby Sister: She is basically adopted by the entirety of Class 1-A . Midoriya and Mirio jointly have Big Brother Instinct, Tsyu says Eri reminds her of her own little sister, and Aizawa becomes her legal guardian. Mirio is her actual caretaker, and Nejire is seen putting her hair into pigtails. Tamaki might be too shy to interact with her, but it may be The Big Three's little sister's as well.
- First-Name Basis: Partly as a result of having Only One Name, and partly due to being a young girl (so people are generally less formal with her), people exclusively refer to her by her first name, even when they generally use last names on others.
- Foreshadowing: Eri's Quirk shows that Quirks aren't always physical abilities, and can potentially be metaphysical forces that warp reality in strange and impossible ways (which rarely happen). Soon after, the revelation hits that One For All isn't a purely physical ability either.
- Gilded Cage: Overhaul gives her a nice room with a comfortable bed and lots of expensive toys. It doesn't change the fact that he exploits her Quirk in an extremely painful fashion to manufacture Quirk erasing bullets. To drive this even further home, the toys she was given haven't even been touched or opened, emphasizing how she's too traumatized to even consider playing with them.
- Goo-Goo-Godlike: She's a six-year-old girl with an incredibly powerful, dangerous, and uncontrollable Quirk that basically ruined her life, causing her to accidentally erase her father from existence, which led her mother to disown her and give her up to people who used her as a source of material to make Quirk-erasing bullets without any care for her welfare. Even after she's rescued, Aizawa notes that her Quirk isn't one that can be easily trained since it only works on living things and testing it out would put lives at risk.
- Heal the Cutie: She's introduced as a quiet, traumatized little girl after accidentally killing her father, being abandoned by her mother and being tortured by Overhaul to make anti-Quirk bullets. Midoriya and Mirio make it their personal mission to make her smile again, and using friendship, treats, and The Power of Rock finally help her to become the Cheerful Child she was meant to be.
- Healing Hands: Since her powers let her rewind living things to a previous state, she can essentially make injuries never happen in the first place with a touch. Of course, if she holds on too long, than she does the opposite.
- Heroic Sacrifice: A non-deadly one, but Eri decided to go away with Overhaul instead of being saved by Mirio and Midoriya during their first encounters with each other because she could tell the two would most likely die in a fight between them.
- Heroic Self-Deprecation: Eri has been used, abused, and told that she's "cursed" so often that she cannot understand why anyone would want to save her, much less be so determined to save her that they would give up their life, or even their own Quirk, to do so.
- Hope Spot: She finally manages to escape wherever she was being held captive and finds heroes willing to rescue her... but has to go back for the sake of those heroes' lives.
- Horned Humanoid: Sports a small horn on one side of her head. When her Quirk activates, sparks can be shown coming off of it. Chapter 167 reveals that the horn is where her Quirk originated from, and also that it has shrunken down to a small bump. In Chapter 256, her horn starts tingling and growing back, indicating that her Quirk is re-asserting itself.
- Image Song: The Season 4 anime ending, "Koukai no Uta" (lit. "Song of a Voyage"). The ending's visuals focus exclusively on Eri, her past, and her current predicament. While the song itself isn't sung by her, the lyrics can apply to her character and seem to be encouraging her not to give up hope that one day she will be able to escape from the Shie Hassaikai, and no longer be forced to live a life full of pain and loneliness.Don't need to be strong, doesnt matter if you have nothing
Just as long as you believe
That will be the one thing that saves you
No matter what kind of pain awaits in the future
Go forth without hesitation!
- It's All My Fault: She blames herself for the events of the Internship Arc. While she did play a part, being a Living MacGuffin, Togata and Midoriya ensures her that it wasn't her fault.
- Living MacGuffin: Of the Internship Arc. She is a MacGuffin Super Person who is being wrongfully detained by Overhaul and the Shie Hassaikai for overtly nefarious plans and that the heroes seek to liberate.
- Madwoman in the Attic: A variation. Her captors do consider that she's indeed too dangerous to be left wandering in society due to her Quirk but also because she's instrumental in their schemes.
- Mafia Princess: Completely averted. While Eri is the granddaughter of the Shie Hassaikai's boss who Overhaul revered, she gets no special treatment from the organization and Overhaul treats her as more of a tool than a human being.
- Meaningful Name: Eri's name is made up of two kanji meaning "break" and "reason/logic"; put together, they can translate as "destruction". This alludes to how Overhaul is using her blood to make a Quirk destroying drug, and how her own Quirk can potentially destroy someone by erasing them from existence entirely. Her Quirk also "breaks logic" by being nothing like any known Quirk in existence, often referred to as a mutation by other characters and having no connection to any Quirk on either side of her family.
- Only One Name: She is the only named character to have no family name. Although she is stated to be Overhaul's daughter, she is never called "Eri Chisaki", especially when it's made clear that he's not her real father anyway. The reveal that she was disowned by her mother at a very young age after accidentally erasing her father from existence could have something to do with it.
- Parental Abandonment: When Eri's Quirk first awakened and accidentally erased her father from existence, her mother was so distraught that she willingly abandoned Eri by handing her over to the Shie Hassaikai, wanting nothing to do with a daughter she believed was "cursed".
- Patricide: She accidentally erased her father from existence when she awakened her Quirk. While this wasn't entirely her fault since she was very young and had no control over her Quirk, her mother didn't take it well at all and abandoned her because of it.
- Power Incontinence: Eri is unable to control her own Quirk; not only is this due to her young age, but she's never even been told what her power was, nor has she ever been given the chance to learn how to use it safely. Her Traumatic Superpower Awakening erased her father from existence, and Overhaul's dialogue indicates she hasn't yet improved in this regard. Midoriya compares her use of her Quirk as slamming her foot on the gas pedal and unable to get off it. By the time Midoriya finally defeats Overhaul, her Quirk's gone so far out of control it's only due to Aizawa that Midoriya isn't Ret-Gone either. By the events of Chapter 293, Eri has a decent amount of control over her abilities.
- Power Nullifier: She is being used to create anti-Quirk bullets. Unlike Aizawa, the bullets attack the Quirk itself instead of just halting the use of one, at least at first. Chapter 156 reveals that it's not exactly a power nullifying Quirk, but a Quirk that can restore a person to a previous state, like rewinding a biological clock.
- Powered by a Forsaken Child: The Shie Hassaikai are using Eri to produce Power Nullifier bullets that disable the Quirk factor through the use of her Quirk, which allows her to rewind things back to a previous state. They do this by harvesting her blood and tissues as a prime matter for the bullets until she's dead. Then their leader, Overhaul, who has the power to deconstruct and reconstruct anything he touches, brings her back to life to repeat the process. Midoriya and Mirio are absolutely disgusted with themselves that they weren't able to immediately save her when they encountered her beforehand after they find out. Even the former Boss of the Shie Hassaikai was appalled by the lengths Overhaul was going to in order to gain power.
- Protectorate: She becomes a precious person whose smile must be protected for Mirio and Midoriya from the moment they get her away from Overhaul. Aizawa is later appointed to oversee her since he can stop her with his Quirk in case her Quirk goes haywire. She is now under the custody of U.A.
- Raised by Grandparents: After her mother abandoned her, Eri was left to live with her grandfather. However, he had left her to be cared for by his adoptive son, who put him into a coma and used her blood to create Quirk destroying bullets. It's still unknown if/when Eri's grandfather would wake up after the Hassaikai is dissolved.
- Rapunzel Hair: She has waist-length hair, probably because her caretakers aren't the kind of people who would care about cutting it when it got inconveniently long. After she's taken into U.A., her hair is straighter and neater, indicating that she's now better cared for.
- Red Eyes, Take Warning: Played with. On the one hand, her Quirk is very dangerous when used improperly. On the other hand, when used properly, it can be very beneficial, and Eri herself is a sweet and adorable girl.
- Scars Are Forever: Without the bandages, she's revealed to have numerous faded scars on her arms and legs from when she was repeatedly broken down and remade by Overhaul's Quirk to provide more blood for his Quirk-erasing bullets.
- Semantic Superpower: Her Quirk, Rewind, is described as being able to "rewind" things to a previous state. So far, she's removed Quirks, undone fusions, healed injuries, and erased people from existence. Because such a power could easily become a Story-Breaker Power, she's hospitalized and feverish at the end of her spotlight arc, which also implies that her power is limited. Chapter 293 adds in "restored Quirks" to the mixture.
- Shadow Archetype:
- To both Midoriya and Mirio. Like them, she possessed an incredible but erratic, potentially dangerous Quirk that she couldn't control. She is also self-sacrificial to the ultimate extreme. Unlike them, she never had anyone to care for her and help her, came to see her Quirk as a curse, and lost any hope of her situation improving until she met them.
- She is this to Tomura Shigaraki. Both of them manifested Quirks which none of their family members possessed. Upon manifesting the Quirks, they accidentally killed a family member and they have dissolved their fathers, albeit with a few differences. Afterwards, both of them were abandoned and were at the mercy of villains. However, Eri was discovered and saved by heroes while Tomura was rescued by All For One.
- She Cleans Up Nicely: After being rescued from Overhaul and taken in by the authorities to be healed, she's finally able to lose the rags she was wearing previously and given proper clothing, looking quite cute in the process.
- Significant Birth Date: Her birthday is December 21, or 12/21. It's the same backwards and forwards—her Quirk is to make things go backwards.
- Story-Breaker Power: Her power would take all the tension out of the story if she could control it. For example, she could rewind All Might back to his powered-up form, undo all of Midoriya's injuries, give back Mirio's Quirk,note etc. For this reason, the end of the Internship Arc sees her feverish and unconscious in a hospital, incapable of using her powers. After she recovers, her Quirk becomes much weaker and somewhat unstable due to the massive amount of harmful Quirk enhancing drugs Overhaul used on her. By Chapter 293, it's revealed that she has enough control to at least undo the damage done to Mirio and has been practicing healing injured bugs and lizards.
- Super-Strong Child: Played for Laughs. Despite being a little girl, she manages to carry a BFS on her shoulder effortlessly, which stupefies Ojiro.
- Superpowerful Genetics: One of the rare Type 2s of this series. Her Quirk is completely unlike any that belongs to her family tree due to a rare genetic mutation that changed it.
- Surprisingly Realistic Outcome:
- Even after being rescued and placed in the care of people who love her and want the best for her, Eri still has a lot of trauma to work through before she can be truly happy, considering how hard her life has been. Saving her was only the first step, but it was the most important one of all.
- Spending most of her early life locked in a dark room underground means Eri's knowledge of the outside world is quite limited. She can barely write, gets holiday traditions mixed up, and initially doesn't even know what heroes are.
- Sweet Tooth: She has a love of candied apples.
- Trademark Favorite Food: She likes apples. Horikoshi has said that since Tokoyami also likes apples, he would like to draw them eating apples together.
- Traumatic Superpower Awakening: She discovered her Quirk when she accidentally rewound her father out of existence with it. This caused her distraught mother to disown her, leaving her in the care of her grandfather and adoptive uncle.
- Troubled Child: After being disowned by her mother for accidentally erasing her father from existence and being horribly abused by her adoptive uncle Overhaul, she's so broken that she's unable to smile, and doesn't even know what heroes are. Midoriya and Mirio greatly regret not saving her when they had the chance.
- Unskilled, but Strong: Justified. Eri's rewinding Quirk verges on being a Story-Breaker Power, but because it only affects living beings and Eri herself suffers from massive Power Incontinence due to her young age and inexperience, it can't be properly trained without having to risk a life in the process, as Aizawa notes.
- Unwitting Test Subject: Eri was a lab rat to Overhaul to create his bullets by using her blood and cells, all which was against her will.
- When She Smiles: After spending nearly her entire page time since her introduction unhappy due to her abuse, she finally breaks out into a huge, happy, uninhibited grin while watching Class 1-A's performance at the U.A. Cultural Festival. The sight of it clearly delights Mirio.
- Wrong Context Magic: Eri has a Quirk that absolutely cannot be a physical ability since it explicitly warps living creatures to whatever is vaguely defined as "backward". Obviously, it's one of the most dangerous powers in the story because no one understands how it works and it can't be researched without sacrificing human lives, so U.A. will stop at nothing to keep anyone else from getting their hands on her after taking her away from Overhaul.
