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

* MaleGaze: Due to her [[https://imgur.com/EMfqP2H revealing hero costume]] and general bearing, she's the subject of much male attention when she walks around.

* BaitAndSwitch: [[spoiler:The end of chapter 415 has a panel of her running away with determination in her eyes after seeing izumi getting steadily overwhelmed in his climatic fight with Tomura, making it look like her power will be vital in allowing him to contend against his enemy's sheer power [[CombinationAttack like they did with Overhaul]]...only for the next chapter to have Ectoplasm stop her in her tracks. Not only is an adult hero ''not'' going to allow a child anywhere near such a dangerous battlefield that's hundreds of kilometres away, the fighting against the Villain Army has wreaked and destroyed any transport modules that could potentially be used to reach it. Ectoplasm furthermore points out that after healing Mirio to the point of being able to use his Quirk again, not enough time has passed to allow her to rewind the injuries sustained in the fighting by Aizawa, let alone Izuku, meaning she's forced to remain on the sidelines]].

* 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.

* 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.

* 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.

* BunnyEarsLawyer: Aside her {{dominatrix}} and DoubleEntendre 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.

* DominoMask: She wears a red one as part of her hero costume.

* {{Sadist}}: Watching someone runs away in terror gets her heart throbbing.

* StatuesqueStunner: Even without the heels, she's still 175 cm tall.

* VillainBall: During the Final Exams Arc, Midnight plays the "villain role" for Sero and Mineta. [[spoiler: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, making it justified why she wouldn't be so willing to knock Mineta out.]]

* AccidentalPervert: To his credit, he frantically tries to apologize for it as soon as he realizes what happened.

* TheGunslinger: His weapon is a gun, fitting his cowboy theme.

* InformedAttribute: It's said that he works as a school counselor but we rarely ever see him doing his job or offer his services to the Yuuei kids, especially Class 1-A.

* PetTheDog: [[spoiler: During Final War arc, Rei asks the one of the robots to take her to the place where Endeavor and Dabi fight, so she could help them. Despite ''huge'' danger it can cause to her and the robot, it agrees and says that they exist to fullfill human's desires, while making a thumb's up.]]

[[folder:Eri]]

* SuperCostumeClothier: He's the head of UA's Development Studio that creates the gadgets and costumes the students wear.

* {{Expy}}: Shares the same name as the villainous politican from ''[[Manga/Akira]]'', given both have rat/mouse themes. However, ''this'' Nezu plays an unambiguously heroic role in ''My Hero Academia'' by contrast.

* 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.]]

* BewareOfTheNiceOnes: He deeppy cares about his students and teacher's staff, but when he will have an oppurtunity to show his "evil" side, he WILL use it.

* SenpaiKohai: ''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.

!!!'''Quirk:''' [[MakeMeWannaShout Voice]]

* BigWordShout: Justified as his Quirk is [[MakeMeWannaShout making his own voice louder]]:

* 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.

* 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.

* PersonalityPowers: Mic has the capability to [[MakeMeWannaShout make his own voice louder]], and is fittingly the LifeOfTheParty.

* BadassBaritone: He is a huge, strong hero with a deep, imposing voice.

* BadassBaritone: In English and Japanese, he's cast with a pretty deep voice.

* BadassBaritone: He speaks with an unnaturally deep, chorused voice that only adds to his already menacing appearance.

* SurprisinglyRealisticOutcome:
** [[spoiler: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.]]
** [[spoiler: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.]]

* DressedLikeADominatrix: 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.
