History Characters / MyHeroAcademiaSchoolFacultyAndStaff

* EveryoneHasStandards: For all his fervant favoritism towards his class, even he gets annoyed by Monoma's ranting after 1-B loses the Joint Training Exercise and tells him to quiet down.

* DarkIsNotEvil: Very creepy-looking, but he's a hero and a teacher.

** 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 [[BigBad All For One]].

!!! '''Voiced by:''' Eiji Hanawa (Japanese), Zach Bolton (English), Rubén Moya (Latin American Spanish/TV series)

* TrueCompanions: With Aizawa. They have been through a lot together, including the [[spoiler: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 [[spoiler:Kurogiri's revealed to possibly be a Nomu-fied Shirakumo.]]

* HandicappedBadass: 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.

* BandageBabe: While under the control of the Hassaikai, she has bandages wrapped around both arms and legs, which combined with her general BrokenBird 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.

* AmbiguouslyHuman: 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.

* AnimeHair: While it isn't RapunzelHair, it's still very long and is styled akin to a conifer tree. She had shorter hair when she was young.

* RapunzelHair: 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.

* BeautyIsNeverTarnished: Subverted. [[spoiler: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.]]

* RandomlyGifted: By some quirk of genetics, Eri was born with an extremely powerful but uncontrollable Quirk that none of her family members share.

''Villains'': [[Characters/MyHeroAcademiaVillains Known Villains]] ([[Characters/MyHeroAcademiaLeagueOfVillains League of Villains]] [[[Characters/MyHeroAcademiaAllForOne All For One]], [[Characters/MyHeroAcademiaTomuraShigaraki Tomura Shigaraki]], [[Characters/MyHeroAcademiaDabi Dabi]], [[Characters/MyHeroAcademiaArtificialHumans Artificial Humans]]], [[Characters/MyHeroAcademiaShieHassaikai Shie Hassaikai]] [[[Characters/MyHeroAcademiaOverhaul Overhaul]]], [[Characters/MyHeroAcademiaMetaLiberationArmy Meta Liberation Army]], [[Characters/MyHeroAcademiaParanormalLiberationFront Paranormal Liberation Front]])\\

* OddFriendship: 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.

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.

-->See his [[Characters/MyHeroAcademiaAllMight page]].

** "First period is English! In other words: it's '''JAM TIME'''! Been an age since I stood on this stage! Did you miss me?!"

* TheFaceless: 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.

* NatureIsNotAToy: 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.

* SempaiKohai: ''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 CoolBigSis to them both, getting Eraserhead his student internship as well as his eventual teaching position a decade later.

* TwoGirlsToATeam: Recovery Girl and Midnight are the only known female members of the faculty at U.A. Although later retroactively averted, [[AllThereInTheManual when a character book confirmed]] that Thirteen (who has never been seen out of costume) is also a woman.

* FangsAreEvil: 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.

* MeaningfulName: 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.

!!! '''Voiced by:''' Creator/HiroyukiYoshino (Japanese), Creator/SonnyStrait (English, Season 1), David Trosko (English, Season 2 onward), Jorge Luis García (Latin American Spanish/TV series)

* BewareTheSillyOnes: He might be the LifeOfTheParty, 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. [[spoiler:His deduction proved to be correct after it is revealed one of the students -- Aoyama Yuga -- was the spy for All For One and had given reconnaissance to him]].

* GaleForceSound: One of Present Mic's most powerful attacks, "Loud Voice," is effectively a sonic boom that blasts away nearly anything in its path and can do [[PersonOfMassDestruction extreme structural or bodily harm]] depending on the projected volume, pitch, and frequency.

* LivingEmotionalCrutch: Heavily implied to have become one to Aizawa after [[spoiler: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. [[TrueCompanions 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.

* NoHoldsBarredBeatdown: He delivers a brutal one in Chapter 269 to [[spoiler: the doctor]] who was responsible for Shirakumo's death and Aizawa's emotional breakdown.

* ObfuscatingStupidity: 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 [[spoiler:their deceased high school friend Shirakumo and the League of Villains' Kurogiri]].

* TragicBromance: With Oboro Shirakumo, a close friend and classmate of his and Aizawa's [[spoiler: who died during their second year at U.A.]] While Aizawa became even more detached and cynical, [[spoiler: 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, [[SadClown no matter the cost]].
* TranquilFury:

* TrueCompanions: With Aizawa. They have been through a lot together, including the [[spoiler: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 [[spoiler:Kurogiri's revealed to possibly be a Nomu-fied Shirakumo]].

->''"Listen. When it comes to fighting... It's all about making use of your particular strengths.''

* DeadHandShot: [[spoiler:The last that's seen of her in Chapter 296, [[DeadHatShot alongside her crumpled mask]]]].

* SadistTeacher: [[ZigZaggingTrope Zigzagged]]. While she does have sadistic tendencies, she genuinely wants to help students and guide them towards their goals.

* AnimalSuperheroes: Naturally. Being a hero is one of the requirements for one to become a teacher at U.A.

* BigGood: A formal example due to his position as principal of U.A.

* Fiction500: In Chapter 323, Endeavor explains that Nezu’s contributions to Quirk education are so pervasive that it’s made him massive amounts of money, which explains how he can construct replica city blocks and industrial areas for training grounds and active robots as live punching bags that all get smashed on a regular basis, all seemingly without any government financial aid and [[spoiler:completely revamped U.A’s 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 also paid for this entire system out of his own pocket.]]

* TheStrategist: 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.

** 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 [[spoiler:the League of Villain's Vanguard Action Squad and the Shie Hassaikai]].

* BlessedWithSuck: Eri can [[spoiler:rewind living beings to a previous state]]. A bout of PowerIncontinence led to her [[spoiler: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.

--> ''Don't need to be strong, doesn’t matter if you have nothing''\\

* {{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.

* SemanticSuperpower: Her Quirk, Rewind, is described as being able to [[spoiler:"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 StoryBreakerPower, she's hospitalized and feverish at the end of her spotlight arc, which also implies that her power is limited. [[spoiler:Chapter 293 adds in "restored Quirks" to the mixture.]]

* AdultFear: Eri is a prisoner of her [[spoiler:adoptive uncle]], who controls her by threatening to kill his enemies [[spoiler:and even her, with the power to immediately undo it.]]

* TheBusCameBack: He plays a small but major role in Chapter 346, [[spoiler:making food en masse for Momo Yaoyorozu to convert into lipids so she can make the parts needed for the moving concrete panels after Shigaraki destroys some.]]

* BeautyMark: A small one dots her left cheek just below the eye.

[[caption-width-right:350:Space Hero]]
[[caption-width-right:350:[[labelnote:Click here to see her without her helmet]]\\

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.

[[caption-width-right:160:Erasing Hero]]

->''"I'm sorry to tell you... that for the next three years... U.A. will run you through the wringer. That's "Plus Ultra". Use your strength to overcome it all. So bring it."''

Class 1-A's homeroom teacher. He's a bit of a LazyBum, 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.

* TwentyFourHourArmor: 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.
* AmputationStopsSpread: [[spoiler: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.]]
* AirplaneArms: He runs like this while fighting.
* AnArmAndALeg: [[spoiler: He cuts off one of his legs in Chapter 282, after it's hit by a Quirk-Eraser.]]
* AntiMagic: His Quirk effectively nullifies one other person's Quirk, as long as it's an emitter or transformation Quirk.
* ApatheticTeacher: [[PlayingWithATrope 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 LazyBum 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 WackyHomeroom.
* ArtificialLimbs: [[spoiler:After hacking off his right leg to avoid the spread of a Quirk-erasing bullet, Aizawa received a mechanical replacement with digits and joints.]]
* AscendedExtra: Downplayed. While he's a main supporting character in the main series, he's a full-on main character in ''Manga/MyHeroAcademiaVigilantes'', having multiple chapters focused on him and his past.
* BadassBaritone: Aside from being a very formidable Hero, Aizawa also has a pretty deep voice, courtesy of Creator/JunichiSuwabe.
* BadassInDistress:
** During the battle at USJ, Aizawa is beaten to the ground by [[TheBrute 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, [[spoiler:Aizawa is hit by [[TheDragon 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.]]
* BadassTeacher: Although his teaching methods can be rather questionable, Aizawa is a very competent pro hero who is protective of his students.
* BandageMummy: 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.
* BigDamnHeroes:
** 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 [[spoiler:Shigaraki grabs Ryukyu to turn her to dust, appearing in a nick of time to disable Shigaraki's Decay.]]
* BokeAndTsukkomiRoutine: 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.
* BrutalHonesty: 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 [[spoiler:[[KilledOffForReal what happened to Nighteye]]]].
** Unsurprisingly, he's also brutally honest with Aoyama regarding [[spoiler:his being the traitor at U.A., saying that his sins will stay with him forever, and he may not be able to return to U.A. once all is said and done. However, he also says he intends to protect Aoyama, and has no intention of letting him die alone, burdened by guit.]]
-->'''Aizawa''': Those friends of yours like to sugarcoat things, but I'll tell it to you straight.
* BunnyEarsLawyer: 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.
* CantHoldHisLiquor: 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.
* CelebrityIsOverrated: 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.
* CharlesAtlasSuperpower: 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.
* CheshireCatGrin: Occasionally flashes a mischievous, creepy-cute, toothy grin during his {{Troll}} or "logical ruse" moments.

** 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 [[spoiler:Kurogiri is a Nomu-fied Shirakumo]] hits both of them extremely hard.
* ClothFu: His scarf isn’t just a fashion statement, it’s a support item he uses to tie opponents up, or to set up traps.
* CombatCommentator: 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.
* CombatPragmatist: 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.
* TheComicallySerious: Will take things like Nezu climbing out of his scarf with the straightest of faces.
* CoolShades: 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.
* CoolTeacher: 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.
* TheCowl: His general design is based on this, being an underground hero that avoids media attention and works as a {{Foil}} to [[TheCape All Might]].
* CruelToBeKind: 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.
* CynicismCatalyst: [[spoiler: 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]].
* DeadpanSnarker: 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 [[TranquilFury doesn't raise his voice at all]]. Instead, he [[SarcasmMode sarcastically congratulates the two]] for having enough energy left to go all out against each other, despite having just finished with the preliminary hero licensing exam, while restraining them with his scarf, which is not a comfortable situation.
* DeathGlare: He does this when he's angry. Due to the nature of his Quirk, this will also render whoever he's looking at Quirkless.
* DentedIron: 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 UpToEleven in the Paranormal Liberation War Arc, when he goes so far as to [[spoiler:'''cut off his own leg''' as to not lose his Quirk and keep nullifying Shigaraki.]]
* DeusExitMachina: During the Internship Arc. While not really the most powerful man in the room, Aizawa is [[spoiler:absent or held captive by Chronostasis during Overhaul's fights with Mirio and Midoriya, as Aizawa [[AntiMagic knocking out Overhaul's Quirk]]]] would end the battles too quickly.
* DisappointedInYou:
** Towards Class 1-A after the hideout raid: [[spoiler: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.
* DrearyHalfLiddedEyes: His default eye expression, very rarely changed.
* TheEeyore: 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.
* EmbarrassingNickname: Mic has given him a ton of these, including "Prince of Slumberland" ([[FunWithAcronyms P.O.S. for short]]) and "Snooze Master". Aizawa's usual response is to place him in a choke hold until he shuts up.
* EveryoneHasStandards: 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.
* EyeScream: [[spoiler:Aizawa lost his right eye against the Paranormal Liberation Army and now wears an eyepatch, which has obviously handicapped his Quirk.]]
* FightsLikeANormal: 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.
* FragileSpeedster: 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.
* FreudianExcuse: [[spoiler:''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.]]
* GameBreakingInjury: 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.
* GenerationXerox: Yamada comments that Shinso is turning out to be almost identical to Aizawa, right down to the easily underestimated mental Quirk, [[CreepyShadowedUndereyes tired eyes]], [[LazyBum slouched posture]], [[ScarfOfAsskicking capture scarf]], and [[KindheartedCatLover love of cats]].
* GogglesDoNothing: 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.
* HairContrastDuo: The lazy, cynical, and slovenly black-haired Aizawa to his old friend, the upbeat, energetic, and outgoing blond Present Mic.
* HamAndDeadpanDuo: 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.
* HeCleansUpNicely: When he ''has'' to appear before the media, he actually bathes, neatens his hair, and wears a suit.
* HeroicBSOD: Suffered a major one in his school days that he is evidently still healing from, given his reaction to [[spoiler: 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.
* HeroicSelfDeprecation: 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.
* HypocriticalHumor: 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.
* ILied:
** 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. [[spoiler: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.]]
** [[{{Troll}} 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.
* InformedAttribute: 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..." [[spoiler:It turns out that his "expulsions" of the students who fail his Quirk test don't actually stick.]]
* InstantKnots: Can manipulate his capture tape so that it instantly wraps around an opponent.
* IntrovertedCatPerson: 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.
* IveComeTooFar: [[spoiler: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.]]
* JerkWithAHeartOfGold: 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.
** When he learns of the identity of the traitor in his class and meets with said individual, he's both brutally honest and compassionate, and continues to consider said traitor one of his students.
* TheKilljoy: 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|Trope}}, as his SinkOrSwimMentor and SternTeacher 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.
* LaserGuidedKarma: After spending the entire series disciplining his students and doing his best to protect them from villains, [[spoiler: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.]]
* LazyBum: Introduced sleeping on a floor in front of his classroom in a sleeping bag. He also often teaches while in said sleeping bag.
* LifeOrLimbDecision: [[spoiler: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.]]
* LockedOutOfTheLoop: 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.
* LogicalWeakness: 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 [[ExactlyWhatItSaysOnTheTin 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.
* MagicalEye: It's by looking at someone that he can erase Quirks. [[spoiler: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.]]
* MeaningfulName: 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.
* MentorArchetype: {{Deconstructed|Trope}} 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 SinkOrSwimMentor, 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 TricksterMentor 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 EnemyMine, if not become FireForgedFriends. 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.
* MentorInSourArmor: 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.
* MessyHair: His long disheveled hair adds to the LazyBum image.
* MotivationalLie: He passes off his lie of threatening to expel the student in last place as this when he changes his mind.
* MundaneUtility: His hair stands on end when he uses his Quirk, which he'll use to keep his hair from tangling in his scarf.
* NervesOfSteel: 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 StatusEffects, 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 bag''[[note]]a self-preservation tactic used by ninjas is when they would sleep on their left sides with their arms over their hearts as a means of protecting them from being killed instantly as they slept[[/note]] ''and his affinity for cats''[[note]]Ninjas would dress up cats similar to them to make other people believe that they could transform, and some would even keep a cat with them to use the way they dilated their eyes to tell time, though it is debatable whether or not this is true[[/note]] all point to Aizawa essentially being [[NinjaPirateZombieRobot a ninja hero]].
* NoBadassToHisValet: His past history with Ms. Joke makes it so that she leisurely screws with his nerves without fear of consequence.
* ObfuscatingStupidity: Seems like an offbeat fellow but can get just as serious when the time comes.
* OddFriendship: He and Mic are good friends despite their clashing personalities; they actually have been friends ever since they were classmates at U.A.
* OneManArmy: 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.
* OnlySaneMan: 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.
* OriginsEpisode: 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. [[spoiler:The death of his classmate during a villain attack influenced all of it.]]
* PapaWolf:
** 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 HeroicWillpower 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 [[spoiler: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.]]
* PaperThinDisguise: He's virtually unrecognizable to the public and to even hardcore hero fans like Midoriya without his distinctive goggles. This is {{justified|Trope}} 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.
* ParentalSubstitute:
** 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 [[FightsLikeANormal 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 [[CreepyShadowedUndereyes tired eyes]], [[LazyBum slouched posture]], and [[ScarfOfAsskicking capture scarf]].
* PermaStubble: Aizawa has five-o-clock shadow going nonstop. When he is seen ''clean shaven'' after the summer training camp incident, [[OOCIsSeriousBusiness it's a clear sign things have gotten bad]].
* PetTheDog: 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.
* PowerIncontinence: How his AntiMagic 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.
* TheQuietOne: 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.
* ReasonableAuthorityFigure: 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.
* RedEyesTakeWarning: 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.
* RedOniBlueOni: 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...
* RenownedSelectiveMentor: 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.
* ScareEmStraight: [[spoiler: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.]]
* ScarfOfAsskicking: A multi-layered one around his neck which he uses to bind his opponents.
* ScarsAreForever: 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.
* SeriouslyScruffy: Aizawa looks incredibly disheveled and miserable for the most part. However, if forced to go before the press, he will attempt [[HeCleansUpNicely 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.
* SinkOrSwimMentor: 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 [[ThePerilsOfBeingTheBest 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.
* SoProudOfYou:
** [[spoiler:When Yaoyorozu gets her confidence back and resolves to defeat him during her final exam. He doesn't say anything, [[WhenHeSmiles but his smile says it all.]]]]
** [[spoiler: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".]]
** [[spoiler:The little smile on Aizawa's face when seeing Shinso and his team doing well during the Joint Training Arc shows just how incredibly proud he is of the formerly weak and inexperienced boy that he's taken under his wing.]]
* SpellMyNameWithAnS: His first name can be spelled "Shōta", "Shota", or "Shouta".
* TheSpock: 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.
* SternTeacher: At first, he seems to be an ApatheticTeacher, but it eventually comes to light that he just has high standards and very low opinions of those who don't meet them.
* StoryBreakerPower: 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 of the big bads would have a chance against him one on one. If he didn't have any LogicalWeakness built into his ability and the way it functions, then the big time villains would never have a chance of beating the heroes.
* TheTell: His hair inadvertently reveals what his Quirk's weakness is during the USJ Arc.
* ToughLove: 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.
* TragicBromance: With Oboro Shirakumo, a close friend and classmate of his and Yamada's [[spoiler: who died during their second year at U.A.]] Aizawa became much more [[TheStoic socially isolated]], combat-oriented, and cynical of other heroes and the hero industry as a whole after [[spoiler: Shirakumo's death]], effectively shaping him into the brutally efficient underground hero he is in the present day.
* TragicKeepsake: His goggles. [[spoiler: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.
* UsedToBeASweetKid: 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 TheEeyore.
* VillainRespect: Due to his status as a OneManArmy and {{Determinator}}, Aizawa seems to be the one hero that Shigaraki actually respects.
* VitriolicBestBuds: The light novels reveal him to be this with Mic. Mic constantly annoys Aizawa by giving him {{Embarrassing Nickname}}s, 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.
* WeakButSkilled: 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.
* WeaksauceWeakness: His Quirk would be even more useful if he didn't suffer from dry eye.
* WhatTheHellHero:
** 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 AgreeToDisagree with Aizawa.
** In the aftermath of the Hideout Raid Arc, he states that were it not for [[spoiler:All Might's retirement]], he would not just have expelled Midoriya, Kirishima, Iida, Yaoyorozu, and Todoroki for [[spoiler:making an unsanctioned attack on the League of Villains]], but ''every single student in Class 1-A save [[LockedOutOfTheLoop Hagakure, Jiro]], and [[spoiler:[[DistressedDude Bakugo]]]]'' simply for knowing about the plan and doing nothing to stop it.
* WhenHeSmiles: 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.

[[caption-width-right:280:Blood Hero]]

->''"Class A stole the spotlight every time in the first semester, so the second semester's gonna be Class B's time to shine. Got that? Not Class A. Us!"''

The homeroom teacher of Class 1-B. His Quirk is "Blood Control", which allows him to control blood.

* BadPowersGoodPeople: Manipulating and weaponizing blood is hardly a heroic power, but he is still a pro hero and a teacher.
* BadassBaritone: He is a huge, strong hero with a deep, imposing voice.
* TheBigGuy: As imposing and solid as Endeavor.
* BilingualBonus: His surname, Kan, means blood, but in Turkish.
* BloodyMurder: He can weaponize blood.
* CharacterizationMarchesOn: 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.
* CoolTeacher: 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.
* EveryoneHasStandards: For all his fervant favoritism towards his class, even he gets annoyed by Monoma's ranting after 1-B loses the Joint Training Exercise and tells him to quiet down.
* FangThpeak: Not obvious in the original Japanese, the English dub does give him this speech pattern.
* FangsAreEvil: 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.
* HeroesLoveDogs: It's mentioned in his profile that he has a dog at home.
* HeroicBuild: A tall and conspicuously muscular man.
* LargeHam: Proves to be this in the Joint Training Arc, much to Class 1-A's annoyance.
* MeaningfulName: 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.
* NotSoAboveItAll: 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.
* OurVampiresAreDifferent: He has fangs like a vampire and a blood motif, but none of the other classic vampiric traits.
* PerpetualFrowner: 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.
* RedAndBlackAndEvilAllOver: 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.
* RedIsHeroic: A blood-red costume and a known hero and teacher.
* ShoutOut: To the Romanian Prince [[https://en.wikipedia.org/wiki/Vlad_the_Impaler Vlad Tepes]], who inspired Literature/{{Dracula}}, hence his hero name and blood-based Quirk.
* SitcomArchNemesis: 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.
* SpellMyNameWithAnS: 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.
* XMarksTheHero: His lower left cheek sports an X-shaped scar.

[[caption-width-right:325:Voice Hero]]

->''"The great hero Napoleon Bonaparte once said... 'True heroism consists in being superior to the ills of life.' Plus Ultra!! Break a leg, everyone!!"''

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.
----
* AnimeHair: 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.
* BadBadActing: His acting is just as loud and over the top as everything else about him.
* BadassTeacher: 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.
* BewareTheSillyOnes: He might be the LifeOfTheParty, 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. [[spoiler:His deduction proved to be correct after it is revealed one of the students -- Aoyama Yuga -- was the spy for All For One and had given reconnaissance to him]].
* BigWordShout: Justified as his Quirk is [[MakeMeWannaShout making his own voice louder]]:
-->'''Present Mic:''' YEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHH!
* BigYes: This is actually ''one of his attacks'', where he simply screams "''YEAH!''" at an enemy as loud as he can. With [[MakeMeWannaShout the way his Quirk works]], it's actually pretty effective.
* BrickJoke: During the entrance exam, Midoriya mentions that Present Mic hosts a weekly radio show. During the Final Exams, he plugs it while Aizawa is narrating his BossSubtitles.
* {{Catchphrase}}: "[[GratuitousEnglish Everybody Say Hey!]]"
* ChildhoodFriends:
** With Shota Aizawa. They've known each other since high school at the latest 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, [[NiceGuy Oboro]] [[{{Cloudcuckoolander}} Shirakumo]], was believed to have died during their second-year, but it's later revealed that [[spoiler:he may in fact be Kurogiri, who is now a Nomu and appears to share a base Quirk with their deceased friend]].
* CombatCommentator: Provides running commentary on the events of the U.A. Sports Festival, including the one-on-one matchups that happen in the final stage.
* CoolCar: Mic drives a 1966 Ford Mustang Shelby [=GT350=], perhaps one of the flashiest examples of classic American muscle cars anybody could own.
* CoolShades: Wears these as part of his hero attire, but not while in plainclothes.
* CrouchingMoronHiddenBadass: 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 and is very intuitive of the people around him.
* DumbassDJ: He can be obnoxiously loud at times. Aizawa definitely thinks so, anyways.
* EarlyPersonalitySigns: 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.
* FunPersonified: As long as he isn't upset in dire situations or is legitimately angry, Present Mic is extremely comedic in his appearances.
* FillingTheSilence: 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.
* GaleForceSound: One of Present Mic's most powerful attacks, "Loud Voice," is effectively a sonic boom that blasts away nearly anything in its path and can do [[PersonOfMassDestruction extreme structural or bodily harm]] depending on the projected volume, pitch, and frequency.
* GoodIsNotSoft:
** 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. [[TheSpock Aizawa]] tells him to stand down and just wait for the police to arrive.
** Mic has absolutely no qualms about [[NoHoldsBarredBeatdown beating the ever-loving shit]] out of the elderly [[spoiler:Quirk doctor]] who was behind Shirakumo's death and admits to having been after [[spoiler:Aizawa's Erasure Quirk]] all along.
* GratuitousEnglish: Sometimes spouts random sentences in English. Incidentally, he's also Class 1-A's English teacher.
* HairContrastDuo: Upbeat, energetic, and outgoing blond Present Mic to his old friend, the lazy, cynical, and slovenly black-haired Aizawa.
* HellBentForLeather: 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.
* IncomingHam: And how! On top of his official job as a loudmouthed DJ and radio host, Yamada cannot enter a scene without bringing an entire wheelbarrow of HotBlooded ham with him.
** "First period is English! In other words: it's '''JAM TIME'''! Been an age since I stood on this stage! Did you miss me?!"
** "You're '''LATE'''!! You bad boys!"
** "That's it! The MC in me can't take it anymore! Where's the mood music?! And would it kill them to have some commentary?! Someone's gotta inject some soul into this complete buzzkill, All-Mighty!! '''NOW, LET'S GET THIS PARTY STARTED!! OKAY?!'''"
* LargeHam: Even without using his Quirk, he's very on the loud side.
* LargeHamAnnouncer: Of the entrance exams and the U.A. Sports Festival. Naturally, this has even carried over into video games.
* LifeOfTheParty: 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:''' [[DeadpanSnarker Literally anything else.]]
* LivingEmotionalCrutch: Heavily implied to have become one to Aizawa after [[spoiler: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. [[TrueCompanions 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.
* MakeMeWannaShout: 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.
* TheNarrator: 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.
* NoHoldsBarredBeatdown: He delivers a brutal one in Chapter 269 to [[spoiler: the doctor]] who was responsible for Shirakumo's death and Aizawa's emotional breakdown.
* NoIndoorVoice: 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.
* ObfuscatingStupidity: 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 [[spoiler:their deceased high school friend Shirakumo and the League of Villains' Kurogiri]].
* OddFriendship: 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.
* OOCIsSeriousBusiness:
** He's usually the LifeOfTheParty 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 BigDamnHeroes entrance at USJ, it's the first time Mic is shown looking [[TranquilFury 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 [[spoiler: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 [[BewareTheSillyOnes whole mountain of rage]] for a ''very'' long time.
* PersonalityPowers: Mic has the capability to [[MakeMeWannaShout make his own voice louder]], and is fittingly the LifeOfTheParty.
* PersonOfMassDestruction: His Quirk can do an insane amount of damage, both bodily and structurally, if it's not carefully controlled, as demonstrated several times when his lower-level yells cause extreme physical discomfort and burst eardrums while also flattening trees, shattering glass, and even fracturing wood and solid concrete.
* PopCulturedBadass: Comes naturally with his schtick as a famous radio DJ and combat commentator for one of the largest tournaments on the planet.
* PowerIncontinence: 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 [[spoiler:confronting the Doctor, which the [[RageBreakingPoint boiling rage]] in his voice [[GlassShatteringSound cracked his sunglasses]].]]
* PsychoticSmirk: He'll occasionally bust out [[https://68.media.tumblr.com/e6f9dca8d1a0d32b72da7685a9e683fa/tumblr_owe51vPebW1uku9tco3_500.jpg a frightening smirk]] with dartboard eyes visible under the shades.
* RageBreakingPoint: There have been vague hints throughout the series of Present Mic's [[BewareTheSillyOnes well-hidden]] [[GoodIsNotSoft ruthlessness]] and [[SmarterThanYouLook 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 [[spoiler:Shirakumo]] and that [[spoiler:his original target fifteen years ago was Aizawa]] -- and he literally knocks the old bastard's teeth and nose in while manhandling answers out of him.
* RedOniBlueOni: The hot-blooded red to Aizawa's cool-headed blue.
* SadClown: He may outwardly appear to be happy-go-lucky and energetic all the time, but between [[spoiler:Shirakumo's death]] and Aizawa's resulting depression, it's clear that Yamada has sometimes used his exuberance to cope with difficulty in his life.
* SmarterThanYouLook: 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.
* TragicBromance: With Oboro Shirakumo, a close friend and classmate of his and Aizawa's [[spoiler: who died during their second year at U.A.]] While Aizawa became even more detached and cynical, [[spoiler: 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, [[SadClown no matter the cost]].
* TranquilFury:
** 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 [[spoiler:the Doctor]] largely responsible for all of them, Mic doesn't hesitate to [[NoHoldsBarredBeatdown beat the absolute shit out of him]].
* TrueCompanions: With Aizawa. They have been through a lot together, including the [[spoiler: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 [[spoiler:Kurogiri's revealed to possibly be a Nomu-fied Shirakumo]].
* UndyingLoyalty: To his childhood friends, Aizawa and Shirakumo. He has steadfastly stuck by [[TheEeyore 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!
* VitriolicBestBuds: The light novels reveal him to be this with Aizawa. Mic constantly annoys Aizawa by giving him {{Embarrassing Nickname}}s, 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.
* VocalEvolution: 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.
* WeaksauceWeakness: 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.
* WhyDidItHaveToBeSnakes: He's deathly afraid of bugs. This is exploited by Jiro and Koda when they are pitted against him during their final exam.
* {{Workaholic}}: He's a pro hero, English teacher at U.A., and major radio show host.

!!!'''Voiced by:''' Inuko Inuyama (Japanese), Creator/MorganBerry (English)

!!!'''Quirk:''' [[PowerOfTheVoid Black Hole]]

[[/labelnote]]

->''"Your powers are not meant to inflict harm. I hope that you leave here today with the understanding that you're meant to help people."''

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.
----
* AllLovingHero: 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.
* AmbiguousGender: While she is referred to as the "gentle''man'' 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.
* AmbiguouslyHuman: 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.
* AmputationStopsSpread: Chapter 296 reveals that she had [[spoiler:severed her left arm to prevent Shigaraki's Decay from reaching her entire body.]]
* BadPowersGoodPeople: 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 AllLovingHero 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.
* BadassInDistress: Kurogiri critically injures her during the USJ Arc by reflecting the effects of her Quirk back at her through [[ThinkingUpPortals his power]], forcing the students to split their attention between protecting Thirteen and fighting off the villains.
* CallingYourAttacks: "BLACK HOLE!!!"
* CosmicMotifs: 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 [[UnrealisticBlackHole "black hole fingers"]] that can disintegrate matter at the atomic level. Uraraka, who has [[GravityMaster a gravity-based Quirk]], looks up to Thirteen and partially patterns her hero identity on space as well.
* DarkIsNotEvil: A heroic teacher who has the ability to make black holes.
* ExoticEyeDesigns: 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.
* TheFaceless: 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.
* GoodIsNotSoft: 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.
* HoistByHerOwnPetard: 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.
* MeaningfulName: Her hero name, Thirteen, is a reference to the Apollo 13 mission, which famously [[GoneHorriblyWrong went horribly wrong]] and turned into a disaster that the astronauts barely managed to limp home from. Even her prototype's civilian name, Hirooki Anakuro, means "Middle Space".
* NatureIsNotAToy: 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.
* PowerOfTheVoid: 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.
* PoweredArmor: 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.
* SamusIsAGirl: Thirteen's face is hidden until Chapter 296, where her helmet has been partially broken and reveals an unmistakable female face. Until then, no one could confirm the gender of Thirteen by her voice, which was ambiguously feminine.
* UnrealisticBlackHole: Her Quirk can essentially be described as black hole fingers.
* UnskilledButStrong: Kurogiri pretty much says this; being that Thirteen's Quirk is very dangerous, but is at a disadvantage without experience fighting villains.

[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/cementos.png]]

->''"Listen. When it comes to fighting... It's all about making use of your particular strengths.''

A being who can control any form of cement through his Quirk, "[[ExactlyWhatItSaysOnTheTin Cement]]". Also a Modern Literature teacher.
----
* AmbiguouslyHuman: There's a reason he's described as a "being".
* BadassBaritone: In Japanese, he's cast with a pretty deep voice.
* BadassTeacher: He's the Modern Literature teacher.
* BarrierWarrior: A more blunt example than most, one of the most common uses of his Quirk is to raise barriers from cement.
* CurbStompBattle: Gives an absolutely one-sided one to Satou and Kirishima during the Final Exams Arc.
* DishingOutDirt: Anything with concrete he can control.
* HomeFieldAdvantage: Very powerful in urban settings thanks to the abundance of concrete.
* ImpaledWithExtremePrejudice: [[spoiler: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.
* LogicalWeakness: He doesn't fare well in areas that have no concrete for him to manipulate.
* MeaningfulName: His name means "stiff, firm", like cement, referencing to his Quirk. His last name contains the kanji for "stone" and "mountain".
* MundaneUtility: He uses his cement powers to provide the ring for the Sports Festival.
* TheKnightsWhoSaySquee: He's a hero who's a big fan of All Might.
* WakeUpCallBoss: 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.
