** Adding to it was that he wasn't seen in middle school with Katsuki and his other friends, meaning that he either moved away or All For One took him when he was still in elementary school.
*** Fan theories make that one even worse when you consider that he was revealed to be the grandson of the doctor who told Midoriya he didn't have a Quirk. The same doctor a lot of people assume to be the same one we saw with All For One.
*** It was recently revealed that Nomu are made from corpses. Unless this kid is an exception, the Doctor most likely killed him as a prerequisite.
*** The entire confirmation of them being the same person opens up a whole can of worms here. Were Garaki and Dr. Tsubasa always the same person? Did Garaki KillAndReplace him at some point? Was the younger Tsubasa abducted and killed by a man using the guise of his own grandfather, or even his ''actual'' grandfather? And either way, just how many of his patients, which we know include children, must have gone missing because he thought their Quirks might be useful for his experiments?
* Due to the way Magne's Quirk works, the package with a magnetic bar she used in the invasion has some disturbing connotations... Looks like it would've had female and male parts from mutilated corpses mixed inside to work as a magnet. Unless it's just something more along the lines of a harmless hair sample, in which case, [[NightmareRetardant that's fine.]]
* Toru is invisible, all the time, and said Quirk does not apply to her clothes. This has a couple of unsettling implications if you think about what could happen:
** Since she has to be naked for her Quirk to be useful at all, this means she cannot be wearing any sort of armor or protective gear when she fights, and she's never implied to be physically stronger or tougher than a normal person. This puts her at very high risk for injury due to any villain who's capable of perceiving her via their Quirk or who has a wide area of attack. She's also at high risk for collateral damage since her allies can't see her any better than villains.
*** It could've happened very easily when UA was first invaded by Shigaraki. She had been teleported to the plateau with Todoroki, who was unaware of her presence. He used a wide range ice attack which she's lucky not to have been caught in since he implied prolonged exposure would harm the victims.
*** There are other practical concerns with being naked of course. For starters, she's barefoot, which means that she is vulnerable to injury from stones, broken glass, insects, etc. as well as from both frostbite and scolding depending on the temperature. And speaking of the elements, whilst she may have a certain protection from UV rays (although UV and the visible spectrum are actually two completely different things), on a cold day she would quickly run the risk of death.
** There's also no indication that her Quirk turns off if she's injured or unconscious, which means that if she ''is'' injured in battle, her allies aren't going to be able to protect her or give her treatment unless they're lucky enough to stumble onto her without hurting her further.
** And even if they ''do'' find her, unless they have someone like Recovery Girl on hand, treating her injuries is going to be almost impossible since nobody would be able to see exactly what they're doing. Would ''Tooru'' even know how badly she's been hurt aside from knowing where the pain is or what isn't responding to her anymore?
** And then there are the psychological effects of being invisible 24/7; remember ''TheInvisibleMan''?
** While the manga seems to imply Tooru's Quirk is light-manipulation based (as mentioned on her character page) and mean that things like her eyelids could be blocking out light like everyone else's from her own perspective Mirio's Quirk brings up an interesting point for other "invisibility" Quirk bearers: Light passing through a person's eyes without catching any light (which assumedly would make at least the pupils of the eyes visible) would mean that person is ''blind'' as long as they are invisible, and even if they weren't blind to start with eyelids that can't protect them would put them at higher risk of going blind anyway.
*** But obviously her Quirk doesn't really work like that since she probably has a RequiredSecondaryPower.
* Recovery Girl's Quirk is so rare and so useful in healing other people who are hurt by U.A.'s rigorous training and recently, villain encounters, that one must wonder how far back U.A. will be set if she dies.
** Fortunately, most people with healing Quirks seem to go into medicine, and there seem to be specific laws allowing healers to heal people, so a school of UA's prestige would likely find another.
* TheReveal of Toga Himiko's Quirk is full of this:
** First, the real Camie is either dead or has been kidnapped by the villains and possibly used to create a new Nomu.
** If Toga has been impersonating Camie for three days straight, does that mean she has gone to her home and interacted with Camie's family without being discovered? Imagine those folk going about their lives as usual without noticing anything aside of their daughter/sister acting "a bit weird lately".
** Toga can, as far as we know, impersonate Izuku and Ochaco with only people who know them really well being able to tell the difference. The things she could do with this advantage are pure ParanoiaFuel.
** This is alleviated with the latest Hassaikai Arc giving an explanation. Toga can only maintain about a day with a cup of blood, meanwhile, the blood she got from Izuku doesn't fill a full cup. So she can't hold the transformation for long either way. Though still, the ParanoiaFuel is still there.
** Also, how much blood would Toga have taken if she was able to impersonate Camie for three days straight?
** A little alleviated that Camie is alive in Chapter 164.
* The fact that One For All grows stronger with each user. Normally, this would be an unquestionable benefit, but in this case, it also puts a heavier strain on the user's body. While this can be overcome by learning to only use a fraction of the power, it can be hard without first getting used to the Quirk, meaning eventually the Quirk will become useless as its first use would just tear the user's body apart well before they can learn to control it.
** This also highlights the benefit of passing One For All to a Quirkless successor, as Nana did with All Might and All Might did with Deku. Because that person doesn't have any extra power outside that of a normal human's to add to One For All, the power compiled into it for each new Quirkless user is greatly lessened when compared to passing it on to someone with their own Quirk. This, theoretically, helps delay that dangerous [[DeadlyUpgrade "using this power equals death"]] scenario that could happen many, many generations down the line.
*** Hopefully, they will take a lesson from All For One and pass it to someone with shock absorption, regeneration, or some other Quirk that could mitigate the damage.
* Once the One for All's owner selects a successor and passes the power, the previous owner starts losing his/her power as the successor grows stronger. That means that, when Sensei went after Nana, who had already passed her Quirk to All Might, she wasn't even close to her prime while he was at his best; considering that it took All Might's full power to defeat him the first time, Nana was on the receiving end of a horrifying CurbStompBattle.
* Kirishima has a minute scar in the upper corner of his right eye [[AllThereInTheManual from the moment his Quirk activated for the first time without warning and he accidentally sliced himself while rubbing his eyes.]] [[EyeScream What if he rubbed his eye a little lower?]]
** Here's a fridge horror based on that: think of all the ways the class found out about their Quirks. Sato for example probably ate some sugar at some point and became a really strong, mentally slowed toddler. Think of how often little kids are offered cookies, juices, and other things with sugar in them, and imagine how that might turn your kid out of nowhere into the equivalent of a gorilla. That's not even getting into some other Quirks that could have been really unpleasant to discover at random...imagine baby Mt. Lady randomly growing massive one day and how that must have freaked her parents out.
** We've seen how Tokoyami's Quirk gets very uncontrollable and dangerous at night. And that's when he's a teenager. Now, what about when he was just a small child who had only just found out about it and didn't understand? The scenarios are through the roof. Did his parents tuck him to bed and turn off the lights only to wake up seeing this unknown menacing shadow tearing up their son's room? What kind of psychological effects could have on him?
** It gets even more horrifying with some of the Quirks we've seen that can't be turned off... like Shigaraki's "Decay" Quirk. It's implied that he inadvertently ''killed his own father with it'' as a very young child.
** Try 'his entire family', per Chapter 222. Where do you think he got his hands?!
* The knowledge that Bakugou's Explosion is the result of the combination of his parent's nitric acid and glycerin Quirks is at face value a neat little bit of trivia. Then the Quirk Singularity is described as new, more powerful, and uncontrollable abilities emerging from different Quirks mixing over the generations. Bakugou's strength may not just be the product of all his training.
** Granted, Bakugou's Quirk wasn't nearly as powerful when it first manifested, since he could only create small sparks as a child. But if he truly is affected by the Singularity, any children he has might be able to produce larger and more erratic explosions right off the bat.
*** Or produce "explosions" of an entirely different sort (say an antigravity explosion or cryogenic blast)
* In Episode 28, a newspaper is seen with pictures of five heroes killed by Stain. [[https://static.tvtropes.org/pmwiki/pub/images/rip_mr_roboto.png At least one of them was]] ''[[FreezeFrameBonus among the background extras]]'' in the Sports Festival Arc.
* The fact that Sir Nighteye's death along with Mirio losing his Quirk could have been prevented if Midoriya and Mirio decided to save Eri when they first saw her makes this a Fridge Tearjerker than anything else. The full weight will certainly ''crush'' Izuku, assuming he hasn't figured it out yet.
** It will be even worse for Mirio because he was the one who stopped them from saving her. Particularly since his Intangibility would have made it ''easy'' to defeat Overhaul at that time (Overhaul has to touch people to affect them which gave Mirio a considerable advantage against him as seen when they actually fought).
%%* Far from treating it as a SugarWiki/{{Heartwarming Moment|s}}, [[http://xenosaurus.tumblr.com/post/169889084887/alright-im-going-to-talk-about-endeavor this post]] brings up some UnfortunateImplications about Endeavor's possible "redemption arc." Zero context example.
* The sheer amount of Quirks that the Nomus, and by extension All for One, have, raises the question of just ''where'' they keep getting them. How many people are sought out and dragged away for power confiscation? More unnervingly the fact that this went unreported or untraced makes you wonder what happened to the people whose Quirks were removed, seeing as the process didn't kill Ragdoll.
** Fortunately, this one was at least a bit explained with the introduction of someone who can copy stolen Quirks permanently -- one person's durability Quirk could have been reproduced 100 times rather than 100 people getting kidnapped and getting their Quirks stolen.
** A lot of unease can come about when one thinks about all of the possible Quirks he ''could'' have taken. One for All is terrifying enough, but if he had taken Quirks as potent as Present Mic's, Shoto's, or Aizawa's, that might have tipped the battles against All Might into a very bad direction.
*** It's later revealed that they once ''did'' try to get Aizawa [[spoiler: back when he was a student. Instead they got Shirakumo. Imagine if Kurogiri had been able to nullify quirks...]]
* How important Izuku/Deku is to the well being of the dramatis personae of the story at large:
** If Izuku didn't exist or wasn't in the right place at the right time Katsuki Bakuguo would likely have died at the hands of the Sludge -- unless he was absolutely essential for the villain's second escape.
*** Izuku may have been the reason All Might lost the bottle holding Sludge when he grabbed onto his leg, so Bakuguo would probably be safe.
** Assuming that Izuku didn't inherit One For All and end up a UA, Mineta and Asui may well have been killed by the aquatic villains of the League during the attack on the USJ.
*** Without Izuku inheriting [=OfA=], All Might would likely be teaching Mirio's third-year class. As the League attacked the USJ when they did because they had stolen a schedule stating that All Might would be present at that time, if All Might isn't one of 1-A's teachers, the League would not have attacked during 1-A's training.
** Without Izuku at UA, his fight with Shoto Todoroki wouldn't have happened and Todoroki's realization -- and subsequent character development -- that his power was his, not his father's -- wouldn't have occurred, at least not at that time.
** Without that development, Shoto likely wouldn't have interned with his father and ended up in Hosu, absent as well would have been trainee hero Deku interning with Gran Torino -- both ending up in Hosu.
** Without Izuku and Shoto, Native and Tenya Ida would both have likely perished at the hands of Hero Killer Stain, who would likely still be at large.
** Since he wouldn't be training Izuku/Deku as the successor to All Might, Gran Torino wouldn't have been in Hosu during the attack by the League of Villains and their Nomu, likely leading to the death of several more civilians and a more difficult fight over all.
** With no Izuku, Kouta would have almost certainly been killed by Muscular during the School Trip fight with the league.
*** With no Izuku, the attack on the school trip would have been very different from canon, if it happened at all, as the villains involved in the attack joined the League because of Stain's big speech. Without Izuku, Stain would likely still be at large, resulting in the other villains not being inspired to join the League. Also, it was worried about the likely growing strength of the League that prompted UA to shift the school training trip to the woods, so avoiding that, Kouta would have been nowhere near the training trip and any potential villain attacks.
*** Also, it's confirmed at least part of the League's fascination with 1-A is due to Shigaraki's fascination with Izuku. The traitor who revealed the location probably also revealed that All Might wasn't going to be there, so it's not like they were targeting ''him.'' Their show of power could have been somewhere else without the draw of Izuku being there.
*** With no Izuku to fight Stain, the outcome would have been far worse. Iida went after Stain on his own, and Midoriya rescued him. With no Izuku, Iida and Native (the other hero Stain got a hold of) would most certainly have been killed. Think of how the death of a student during an internship would have affected UA.
** How important Izuku was to rescuing Bakuguo is a matter of debate but anything from the attempted rescue not happening -- potentially letting All For One carry on with his merry madness unmolested -- to it failing -- leading to several student deaths -- or simply succeeding like usual are possible.
** Assuming that Mirio Togata inherited One For All from All Might as was [[MissedTheCall "originally" intended]] in the absence of Izuku, if everything stayed the same and he still jumped in front of that bullet to save Eri, One For All potentially would have been lost forever with nothing to counter All For One (Quirk) if either All For One (Villain) either escaped or passed his Quirk on to Tomura Shigaraki. This does assume that Mirio doesn't weigh the importance of One For All -- and all the lives it may potentially save -- against Eri, and act differently, [[HairOfGoldHeartOfGold assuming that he's pretty much the same otherwise]], it's doubtful he would choose himself over Eri.
*** This also assumes that the increased strength and speed boosts that Mirio would have thanks to [=OfA=] would not have allowed him to defeat Overhaul before the Quirk destroying bullets could be used. In the canon fight, Mirio landed punches on both Overhaul and Chronostasis, which they were able to recover from and continue fighting. If Mirio possessed [=OfA=], those hits would have ended the fight then and there.
*** Not to mention that, thanks to One For All super speed, he would have probably been able to take Eri out of the bullet's way without being hit by it, not to mention that, thanks to the huge training he already had for his own Quirk, he probably would have way more than just 20% by that point, if not directly 100%, so he would most likely one-shot Overhaul anyway
* From what can be seen on his character sheet/beneath his overall attire, roughly 80% of Dabi's body appears to be either rotting, slightly mummified, or severely burnt. We've no idea how he received those injuries, at least at this point in the series. Given Dabi's "Cremation" Quirk and overall character, it's not inconceivable to think he did that to himself; but it's just as likely he received those injuries in a fight... which must have been ''some'' fight. Either possibility seems equally horrific.
** If Dabi's skin is burned that severely and he doesn't have some kind of pain resistance Quirk on top of it... this troper would hate to be him.
** Chapter 267 reveals that Dabi is physically incapable of crying because his tear ducts have been burnt away. The psychological implications of that are not pretty.
** He did indeed do that to himself, and keeps doing so. He has an enhanced version of Endeavour's Quirk, but his body was born with a resistance to ''ice'', like his mother. So he hurts himself even more with his power. And Endeavour's less powerful Quirk takes already a heavy toll on him.
* A bit on the light side here, but Gang Orca is only the '''THIRD''' most villainous seeming hero, meaning there are two more heroes each with a more passing resemblance to a villain than him. One can only shudder at the idea of the reasons for that.
** Just the fact that a list like that even exists is pretty demoralizing. Especially for Gang Orca, who is said to be self-conscious about how frightening his appearance is to children.
* A big one involving the Heights Alliance and the possibility of a traitor in U.A: now all of the students are in a single place. If the traitor was ordered to eliminate all of Class 1-A or decided that they were nearly exposed and needed to act immediately while they still could, they'd all be in one spot as opposed to being scattered all over Japan as they previously had been. In trying to protect the students, U.A. may have unintentionally made them all the more vulnerable to a single mass murder spree or event. For a rough example of how various traitors could do so...
** A Toru traitor could slip around completely invisible and stab everyone in their sleep.
** A Kaminari traitor could start an electrical fire and burn everyone alive in their sleep.
** A Sero traitor could tape everyone's mouths and limbs down to suffocate them [[RunningGag as they sleep]].
** A Jiro traitor could use her earphones to break the building's support pillar, dropping the thing on everyone in their sleep.
** A Shoji traitor could spawn numerous hands to hold down his victims as he either smothers, strangles, or simply breaks their necks. [[RunningGag As they sleep.]]
** A Kota traitor could command an army of ants to eat everyone alive, [[RunningGag as they sleep]].
** A Mina traitor could burn or ''dissolve'' everyone with acid as they sleep.
** A Mineta traitor could suffocate people with sticky balls [[OverlyLongGag as they sleep]].
** And if the traitor is a teacher, then he/she can easily go to the dorms without being suspected of anything.
*** [[BrokenRecord As they sleep]].
* There's another possibility for a UA traitor that makes it worse. Whoever the traitor is, they could be being blackmailed into it by means of a HostageSituation and having no choice but to comply with their handler's commands. Think about it; they'd be forced to ruin relationships they probably cherish simply because some asshole decided to turn them into a pawn [[IHaveYourWife by threatening their loved one]].
** This would make even more sense if one of them was a student...
** It's possible that the principle subscribes to the blackmail idea. While All Might believes that his students "have the heart of a true hero", Nezu agreed with him. However, while Nezu may believe in that, he likely doesn't exclude the possibility of them being blackmailed into doing so.
* Eri's power highlights a terrifying FridgeHorror about Quirks in general: they aren't decided by someone's personality, and aren't some sort of mutant powers that follow standard comic book logic. You're either given them by an outside force, awakened to them by random factors from the spread of Quirks across humanity, or were born with one. Being born with a Quirk can be manipulated, passed on, and even combined in due time, as Todoroki is living proof of -- but Quirks can completely disobey genealogy rules at random. And Eri was born with the Rewind Quirk when not a single person in her family line ever exhibited any traits of anything matching it. It's entirely possible that a friend, family member, or even your own ''children'' can just suddenly awaken to a new and extremely dangerous Quirk, and kill you, others, or even themselves with it in the process. And there's ''nothing you can do to prevent or know about it ahead of time.''
** That's not even getting into the potential problems this could cause in families. How many children like Eri or Tenko Shimura in such situations ended up being accused as not being random power mutants, but the results of affairs? After all, Quirks are generally inherited from parents. If your child has a Quirk very different from your own, it is easy to assume it isn't because of a rare mutation.
* Eri overusing her Quirk on Deku gives her an intense fever. It's unknown if this is a one-time incident or if this happens every time she exerts herself. If it's the latter, imagine how bad it must have been when she used her Quirk for the very first time as a toddler. Especially since [[AbusiveParents Eri's mother considered her cursed and likely didn't do anything to help her sick daughter.]]
* The Nomu, High-End, expands upon the Fridge Horror that Nomus were once people. His obsession with strength and finding new opponents, and not to mention the very similar Quirk that allows him to increase/expand his muscles, may remind some people of Muscular. While it's left unconfirmed if Muscular is still imprisoned, this implies that the League of Villains might have got him out and somehow turned him into High End. So not only are Nomus people, but the [=LoV=] can make them without All for One's assistance.
** Fortunately it turns out that Muscular is in fact arrested, that they can duplicate Quirks, and High End was just some other aggressive crook. Not good for the aggressive crook, but Muscular himself is perfectly fine.
* Remember back when everyone took Aizawa's fitness test and how Midoriya ended up dead last? Seems like a case of InformedAbility since some of the others have Quirks that wouldn't help in ''any'' of the tests, but what if it's not? We already know Aizawa would be gunning for Midoriya from the start (as stated by All Might). What if Aizawa deliberately rigged the test just to get an excuse to expel Midoriya? If it's true, then the only reason Midoriya wasn't expelled at all was that he showed his potential to Aizawa during the ball throw. Makes one wonder how many other students were expelled through the same means.
** Delving into Aizawa's backstory offers some NightmareRetardant in that the threat of expulsion is actually his method of training his students on how to deal with 'death' by exposing them to scenarios where they could or would realistically lose all hope of their dreams coming to fruition if he either actually followed through on the threat or didn't 'change his mind' afterwards. Basically, he's deliberately invoking Nightmare Fuel in regards to his students' ambitions to prepare them for an unfair and unforgiving career.
* A lighter horror, but a lot, and I mean ''a lot'' of the Sports Festival matches would have been a lot less ideal if one side had lost instead of won.
** Shinshou vs Todoroki: with how upset Todoroki was, it would not have been hard for him to provoke Todoroki to trigger Brainwashing.
** Sero vs Midoriya: The move Sero used on Todoroki ''would'' have been hard for Izuku to get out of. Breaking his feet would not snap him out of tape, and any broken arms would have stopped him from moving his arms.
** Kaminari vs Iida: Wide range electric attacks would have caught Iida no matter how fast he moved.
** Hatsume vs Ibara: Even if she wanted to win, Ibara would be on to her antics, and her vines could tear her tech apart.
** Yaoyorozu vs Mina: She could produce bases to counter her acid before it could get used.
** Aoyama vs Tokoyami: His navel laser is one, big, bright light, and Dark Shadow doesn't like light.
** Teststetsu vs Bakugo: If he could deal with Todoroki's fire, explosions would be much easier even with less training.
** Uraraka vs Kirishima: Kirishima would not be as prone to hitting her, and even trying to get close would just get her to levitate him into helplessness.
** Midoriya vs Iida: Plenty of notes, Midoriya has the speed to help handle Iida and the agility to not be directly caught up. He'd also want to get back at Iida for sneaking Recipro by him, giving him motivation.
** Ibara vs Todoroki: A bit less, but her vines might be able to get past his ice by going underground and bypassing his strategies.
** Ashido vs Bakugo: Also a bit less, but she'd at least be at a better elemental match-up than Tokoyami.
** Kirishima vs Tokoyami: Actually fairly less beneficial, assuming Kirishima can't fisticuff through Dark Shadow.
** Iida vs Bakugo: He could dodge Bakugo's explosions easier and would not have the resource/mental hangup problems Todoroki had.
** Tokoyami vs Todoroki: Without the fire power in full use, Dark Shadow could sneak around and over the ice attacks with Tokoyami in tow. He'd be harder to lock down.
* Just ''what'' Quirks and techniques did All Might and All for One do to each other to leave them with what injuries they left the fight with?
** This troper likes to imagine that, despite his years in America training with OfA and getting stronger, All Might never forget the desperation he felt at having to leave his master behind to face All for One in a weakened state. So when he finally had the chance to fight his enemy face to face, he held nothing back and probably threw a United States of Smash guided by bloodlust more than heroic reciprocation. As for All for One, given what has been learned about his motivations, namely [[spoiler: trying to steal One for All back from its users]], he potentially might have been trying to ''cripple'' All Might instead of killing him, thus weakening him enough to do so, only to get that anger-fueled Smash that wrecked his body enough to cost him the full breadth of Quirks he'd stolen up until then and put him on life support, necessitating the need for a successor of his own in Tomura Shigaraki.
* With the revelation that One for All contains the Quirks of its previous users inside of it comes the freakish reveal of the Black Whip, which nearly kills everyone around Midoriya. From the reader's perspective this is already horrifying up front, but think about it from a larger perspective: the community at large just witnessed Midoriya publicly unleash a Quirk he isn't documented for having at all, in a world where such info can spread like wildfire and just about everyone that wasn't an All for One ally or victim is restricted to solely one Quirk by genetic nature. Midoriya's life could become an absolute ''hell'' if villains or the wrong groups, in general, learn about him, and it might bring others closer to the truth of One for All without any control over it on his part, much less any way for him or All Might to even predict what might happen.
** Even worse, what's to stop people from drawing a connection between Izuku and the multi-Quirked ''Nomu''?
* The fact that Chapter 220 not only made AscendedFridgeHorror the existence of racism against mutant-type Quirks like Spinners, but also that there is an analog to the Klan who pushes for it running around, and given Spinner's own personal history they aren't without supporters still. What of the heroic characters who don't look human, like Ojiro and Tokoyami? Did they ever deal with the C.R.C?
* Toga's PersonalityPowers gives a whole new meaning of horrifying come Chapter 226. According to her backstory and Kizuki, her Quirk made her naturally attracted to blood. If this is true, then how many other Quirks are affecting the personalities of their owners? How many villains are just acting on instincts given to them by their Quirks?
** On that note, does this mean All For One's obsession with stealing Quirks is a result of his Quirk? Or that Shigaraki's desire to destroy everything he hates is because of his Decay Quirk? Evidence for the latter's case is when, as a child, Shigaraki's Quirk didn't activate until he stated "he hates everything". Seems oddly coincidental.
** Back to Toga, the parents' reaction to her Quirk makes you wonder about their own Quirks. Either they had totally different Quirks and Toga was a shocking mutation a la Eri, or they had similar Quirks that were repressed in similar ways. The only difference being they hadn't mentally snapped like their daughter had: yet. It also has the darkly hilarious thought that if they do have similar Quirks that Toga would probably be mentally healthier if her parents were villains who fully embraced their Quirk and took said daughter off on blood 'hunts' (or kicked her out right right then and there with the first bird).
* In Chapter 230, Geten states that, in the society envisioned by the Meta Liberation Army, one's standing in society is tied to how powerful their Quirk is. That's harsh enough already, but... what would that mean for the tiny percentage of Quirkless people still popping up out there? What would happen to a pre-One For All Izuku in that kind of society?
** This is mitigated somewhat by the fact that the SocialDarwinist society seems to be only his own vision. It's still unclear what the Re-Destro's vision (let alone everyone else in the army) is.
** When Slidin-Go tries to pull rank on Hawks he is told off by Skeptic because Hawks is more useful to the league than he is due to the quality of intelligence he provides. The MLA clearly has no respect for loyalty as long as they can obtain an advantage in their operation. What kind of society would these guys build?
* Fridge Tearjerker. Shigaraki became a villain because nobody but All For One bothered to lend a hand to him at his DarkestHour. How different would Shigaraki's life have gone if instead of All for One, All Might saw the hurting child and lent him a hand?
** Gets worse when you consider the implications and All for One's declared standard operating procedure of finding people at their lowest point and twisting them to his own ends. He finds and takes a kid who just killed his whole family by accident with a Quirk he had no way of controlling that had awakened in response to parental abuse by his father. He then proceeds to invoke ''psychological torture'' on the kid by presenting him with the ''severed hands'' of his family to wear as a reminder. And given how much of a PsychopathicManchild the kid grew up to be, you can bet that healthy emotional outlets weren't something All for One felt important to teach. Also, given that he managed to get to the kid before any of the authorities, just how long was he watching the Shimura family, waiting for something like what happened?
* Not much "horror" but still uncomfortable to think. It's been known since their establishment that the hidden purpose of the dorms is to monitor the students more closely by having them living in a single place. As of Chapter 242, set four months later, no conclusive evidence to pinpoint any suspect has been found. So while the question of whether the spy is one of 1-A's students or not still lingers, another can be raised: how much have they pried into their privacy? For all we know, the dorm may be full of hidden cameras and microphones.
* Not as terrifying, more disturbing to consider: Ibara's Quirk turns the hair on her head into vines. Is it ''just'' her head though? Does it affect every body hair she has, even if artistic styling mean it isn't really visible? Is her entire body covered by fine thorns that make hugging her like hugging an abrasive sponge? If she was a guy, had brothers, or inherited the Quirk from her father, would said guy's chest be covered in a spiky version of a CarpetOfVirility? Is her armpit housing a little nest of thorns she could shoot out as an emergency thorn (even if that is probably the least likely due to how her Quirk needs sunlight)? Does she have vines instead of pubic hair she could use in a pinch akin to the LovecraftianSuperpower or VaginaDentata tropes? Heck if you really want to wonder about this trope, look at her [[https://vignette.wikia.nocookie.net/bokunoheroacademia/images/7/72/Ibara_Shiozaki_Profile.png/revision/latest/scale-to-width-down/216?cb=20180527180710 casual clothing]], you'd notice how much of her body it covers. Could just be her being a devout character, or it could be her trying to minimize sunlight contact with parts of the body she doesn't want it on...
** Possible, but unlikely. Have a good look at an image of her, and you'll notice that she has very normal eyebrows, without so much as a tiny bit of green on them. If it really did affect all her hair, her eyebrows and eyelashes would likely be part of that. Her very modest clothing is likely just because she is a modest girl.
* Quirks are explicitly mentioned as being a part of the person using them, something that they consciously control, to varying extents depending on the specific nature of the Quirk. So, what happens if someone with a Quirk has a seizure? Or, in a similar vein to ManOfSteelWomanOfKleenex, they lose control of their Quirk during orgasm? Deku would be bad enough with just the super strength, but what about Bakugo? He sweats nitroglycerin and has the ability to consciously ignite it, but the first part is an always-on thing, so if he lost control during the moment, his entire body would be covered in nitro. Talk about NightmareFuel...
** It would depend on the specific Quirk. Some Quirks require concentration to be activated, which means that scrambling the user's concentration would make them unable to activate their Quirk (or deactivate it, if it was previously active).
* With the reveal that Kurogiri is a special breed of Nomu created using the body of Oboro Shirakumo, a classmate and close friend of Eraser Head and Present Mic during their UA days who died during an internship, it raises many disturbing possibilities about where all the other Nomu came from, as well as how long All For One and the Doctor were making them.
* People say that there's no one All Might has failed to save when he was on-scene. We know, however, that All Might was present at the second incident with the Sludge Villain, and due to his hero timer wouldn't have intervened unless Izuku had been there reminding him of what it meant to be a hero. How many times has All Might been on-scene, but unrecognizable, and consciously decided not to help?
* When you think about it, Kota is ''really lucky'' that he punched mild-mannered Deku in the balls and not, say, Bakugo who just so happened to be standing right next to the latter at the time. The next time we saw Kota he may well have been sporting a face like Todoroki. This also would have interesting implications for Bakugo and the rest of Class 1-A given how the rest of the arc plays out, especially if he was punished for retaliating.
** Regarding that, it was pretty much the Pussycats' fault for taking Kota with them at the camp and not keeping him away from the students, not even after kicking Deku. Also, some counseling, or maybe just seeing a clip of a hero risking their lives to save someone or talking to someone who has been saved by a hero, might've changed his perspective on heroes
* In Chapter 270, it is revealed that Oboro Shirakumo's death was not an accident, but planned by Kyudai Garaki and that the original target was Shota Aizawa, or more specifically, his Erasure Quirk. Just imagine if they had succeeded and the villains had this Quirk in their possession. They could have duplicated it and then given it as a default to every High-End Nomu like they do with Super Regeneration. The heroes would have stood no chance whatsoever.
** Garaki's presence in the story is what elevates [=AfO=] from a crime boss to an EvilOverlord, he provides the technical expertise to duplicate powerful Quirks so that [=AfO=] doesn't have to give up the original, creates the Nomu, facilitates monitoring and theft of strong Quirks through his orphanages and hospitals, and acts as the general support system for the League of Villains. [=AfO=]is even more dangerous than he would have been, and probably even still ''alive'' given the Life Force Quirk that Garaki gave him, because this one scientist was mocked for his theories. If people had treated his theories with less mockery, we wouldn't ''have'' anything from [=AfO=] in series.
** Even worse, Kyudai Garaki is confirmed to be the seemingly random doctor that Izuku had seen at the beginning of the series, the one that notified him of being Quirkless and thus crushed his hopes and dreams. In a way, his anger at society for being disregarded was channeled into cruelly pushing a child away from his dream because he was probably already working with All For One, but that's not the horrible part: as mentioned before, he was manipulating circumstances with children for the League's own ends. Tsubasa, one of Izuku's old friends growing up, is one of the Nomu too. ''Izuku was effectively on the lucky side of the roulette wheel via being disregarded by a MadScientist'', a thin razor's edge away from being kidnapped and horrifically turned into a monster for the sake of killing people and causing destruction, and absolutely no one realized it because he was thought to be useless to society for being absolutely normal. Though this also ends up a case of NiceJobFixingItVillain; had he been even crueler to try to do anything to young Midoriya, or even simply kept tabs on him instead of seemingly disregarding him altogether, [[DidntSeeThatComing we wouldn't have One For All's perfect successor coming out of the woodwork years later to ruin their plans.]]
* What did Moonfish do to wind up on death row, when known serial killers like Stain and Muscular didn't?
** Seemingly cannibalism. Though we don't ''actually'' know their state so it is possible that Stain, Muscular, and All for One are either on or being pushed to go to death row as we speak.
* In his big reveal to Endeavor, Dabi mentions that he'd originally planned to kill Shoto, most likely when the kid was reaching fame but not powerful enough to make it impossible, but then Endeavor being named the top Hero made him change his plans. Shoto probably dodged a blazing-hot bullet inadvertently thanks to his dad; imagine dying at the hands of a brother you thought was long dead.
** Of course, it's doubtful Toya/Dabi is gonna just turn Endeavor to ash and be like, "Okay, revenge complete. Wanna grab some noodles, bro?" afterwards...
* Throughout the series All For One often said he was making Shigaraki "the next me". At first, it's easy to assume he meant his successor, like how One for All is passed down. Come the Paranormal Liberation War arc, and we learn that, thanks to Shigaraki now having the original All for One Quirk, All For One (the villain) can do a VillainOverride and take control, though Shigaraki does fight it. This makes one wonder what All For One exactly meant by [[GrandTheftMe "the next me"]].
** Even worse, the fact that he seemingly knows exactly how the transfer will work raises the possibility that [[BodySurf he's done this before.]]
* As we see a flashback to Hawks' horrifying and abusive childhood, it's too clear the relationship between his parents was devoid of any love, as it was his conception which his father viewed like a curse. At best, there may have been some attraction in the past until his mother was accidentally knocked up; at worst, it's too easy to imagine he's the fruit of his father forcing himself on her. Moreover, it's a blessing a series of circumstances allowed Hawks to rise up from the hellhole he grew up and become an hero, as otherwise his fate could have been to eventually follow in his father's footsteps, ultimately becoming a terrifying villain due to his Quirk with the only hope to the contrary being the possibility the Quirk required more intense training than a street thug could give himself to use as well as Hawks does as a hero.
* Come Chapter 300, we have a different horrifying reason why civilians taking matters into their own hands is a bad thing.
** By the time heroes like Wash show up, several people are injured and/or dead -- either the attackers who were outfought with support items, or the inexperienced civilians failing to safely use them against their assailants.
** Unlike their American counterparts, whose culture is rooted in discipline, self-defense, and protection of their own through deterrence, the Japanese population has virtually no training or ingrained values to properly handle these new support items.
** And while guns are common and predictable enough to anticipate, the variety of Quirks has led to an increase in paranoia, as no one knows what trick the next wielder has, leading to dangerously unpredictable consequences.
** And let's talk about entire towns and shops arming themselves with these weapons -- parts of Japan would eventually be fragmented by warlords exerting control over entire areas, not unlike what happened in Somalia -- assuming All For One hasn't usurped them first.
** Combined with rhetoric and a demoralized population, not only will countless civilians engage in vigilantism, no one will trust each other. Lynchings, accusations, the court of public opinion will not be kind to certain individuals who looked at the others in a funny way.
* At the start of the story, All Might was planning to scout a successor to inherit One For All while teaching at U.A. Then he decided to give the Quirk to Izuku Midoriya, a Quirkless but heroic boy. All Might's old sidekick, Sir Nighteye expressed doubts on his choice (believing that Mirio Togata should have inherited the Quirk), but All Might stuck to his decision. About 300 chapters later, it is revealed that One For All depletes the life force of any Quirk user who inherits it. What is scary is that none of the One For All users knew of this until recently. In other words, had All Might followed his original plan and gave One For All to someone like Shoto or Mirio, they would have quickly died prematurely, without anyone knowing the true cause, and One For All would come to an abrupt end. All Might and Izuku can wield One For All without losing their vitality because they were born Quirkless. The first user of One For All lampshades it, stating that Izuku inheriting One For All from All Might was a miracle that ensured One For All's continued existence. This also means that Izuku is fated to be the final wielder of One For All, since at this point, no other human can wield its immense power.
** This logic doesn't follow as One For All can still be transferred to someone else without killing them if Izuku finds someone Quirkless to give it to. Plus, if the problem is life force being drained, then giving One For All to someone with a healing Quirk would mitigate the damage -- and as later users of One For All gain the Quirks of previous users, then it is entirely possible to remove this problem forever.
*** Except that even a Quirkless recipient like Midoriya is struggling to wield One For All due to its immense strength. Even if Midoriya does find another Quirkless recipient and transfers One For All after training them, the new successor will not be able to use One For All without wrecking their body. It can be possible to transfer it to someone with a longevity Quirk, but the odds of finding that candidate are as hard as finding a Quirkless person. If it is transferred to a person with a healing Quirk, it will still not resolve the issue of life force depletion.
** If Izuku is genetically Quirkless (and not one who had his Quirk removed as some theories go) it might be possible to specifically have a child who is Quirkless with targeted gene selection. In real life, it is possible to aim for certain traits to either avoid a condition or even to encourage it, such as dwarfism. However, if Izuku (and a Quirkless woman) were to specifically do that they'd more or less be intentionally crippling the child and hoping they don't resent their parent so much for it they become a villain with One for All instead. Izuku would also have to convince a 'Mrs. Midoriya' to go along with the plan, which may not be easy or well-conducive to marriage health (if a marriage or any type of relationship would even be necessary, considering modern genetic technology like artificial insemination, in-vitro fertilization, etc.).
* Let's talk about the actions of the Hero Public Safety Commission, shall we? On the surface, the commission has the public's trust just as much as they (used) to trust heroes. Then we learn some of their more dubious actions, like taking in Hawks and turning him into a TykeBomb. THEN we learn about Lady Nagant, and how the HPSC used her as their personal hitwoman, having her assassinate potential threats to Hero Society (from villains, to heroes whose actions would've tarnished the public's view on heroes, to regular people who simply were simply ''[[{{Thoughtcrime}} talking]]'' [[{{Thoughtcrime}} about going against the establishment]]) even before they actually commit crimes. What other actions did the HPSC do to maintain this "peace"? How long have these actions been going on?
** According to [[{{Sleepyhead}} Yokumiru Mera]] in the Provisional Hero License Exam Arc, the HPSC is [[OddlySmallOrganization understaffed]], which is why he's so exhausted from overworking. At first, this seemed to be a simple gag. Then we learn about the HPSC's more dubious actions. Is the reason the HPSC is understaffed because some members wanted to change or expose how the Commission runs things and had to "[[DeadlyEuphemism disappear]]"? Did they try to leave [[ResignationsNotAccepted only couldn't]]? Or, a bit more mundanely, do the higher members of the commission simply not hire new staff so they could keep more [[{{Greed}} cash in their pockets]]?
* Just how far did Kotaro Shimura's abuse go? We know for a fact that he was physically and emotionally abusive towards his son Tenko, and it's all but shouted from a rooftop that his daughter Hana got it just as bad. Considering that his wife and in-laws were barely able to stand up to him, is almost safe to say that there was a level of [[DomesticAbuse spousal]] and [[WouldHarmASenior elder]] violence involved...
* Izuku is at the same time the best inheritor of OFA and the worst possible. Because Toshinori was too. Being Quirkless, they could hold OFA without many side effect. But being self-sacrificing, good {{determinator}}s without any self restraint and care for themselves, Toshinori brought himself to the brink of death more than once and Izuku is following the same self-destructive path, crushed by the responsibilities of his powers.
* At the beginning of the manga, All Might describes maintaining his muscle-form as being like that guy who sucks in his gut when passing by girls at the beach. It’s a somewhat humorous comparison, but makes more sense when we are finally introduced to what he looked like in his prime and you realize that the current All Might’s face (in his muscle-form) is incredibly tight and clenched, giving his wide grin a much more strained look in comparison to the more natural smile he wore in his youth. It becomes a telling showcase of the sheer strain All Might has to exert to continue to use his power, even before he starts to lose strength after giving One For All up to Izuku.
* TheReveal that Aoyama was born Quirkless and received his Quirk from [[TheSociopath All For One]] brings some disturbing possibilities. Namely, that given that his Quirk hurts his body, it's likely AFO deliberately gave him a harmful Quirk, [[ForTheEvulz just because he could]]. [[FromBadToWorse To make matters worse]], given what happened to Lady Nagant when AFO remote detonated the Quirk she had received from him, [[YouHaveOutlivedYourUsefulness Aoyama is also in serious danger of being killed]] for his decision ''if'' the villain found out.
* The idea that eventually, all of humanity as we know it will simply cease to be through Quirks mutating their bodies to properly handle the increasingly-stronger powers they're born with through the generations. We've seen examples of this present all throughout the series, people whose bodies have been altered into almost unrecognisable human forms through their powers and suffered FantasticRacism for it, and how Tomura is blatantly showcasing the end result: A monstrous form of existence that doesn't even bear any resemblance to Tomura's original human body. And the worst part is, ''this is inevitable''. There's no cure to turn people back into being Quirkless humans besides All For One's powers or Overhaul's eraser bullets, and Quirks have become so widespread that humans who ''don't'' have them are almost extinct altogether. At some point in the future, humanity will have evolved into something else entirely through this phenomenon and there's no concrete reason as to ''why'' this is happening, or what the end result will ultimately be.
** And if [[BlueAndOrangeMorality Toga]] is any indication, even their ''minds'' won't be safe from this evolution. [[HumansAreCthulhu Human life as we know it will eventually change into eldritch monsters]], and the there is jack all anyone can do about it.
** At a glance, this almost looks like that even the ''best case scenario'', the defeat of All for One and redemption of all the other main villains will result in nothing more than a EsotericHappyEnding, as humanity is completely screwed whether the good guys win or lose anyway.
* With TheReveal of Endeavor's full backstory on chapter 356, Enji becoming a [[AbusiveParents horrible father to his children]] makes a very dark amount of sense. When Endeavor was a child, he witnessed his own father being murdered by a villain (while the father was implied to be trying to save ''Enji's sister'' no less). Not only that would harden the heart of pretty much anyone, losing his dad at a such a young age would also mean that Endeavor would have no role model or advising figure for when he became a father himself. While his actions towards his family can '''not''' be justified, part of the reason Enji sucks at being a dad is because ''he really doesn't know how to be a good dad''.

* Because of how Quirks work in general, anyone at any time could be born with theoretically ''any'' power, ranging from [[HeartIsAnAwesomePower seemingly harmless]] (like Mineta and his sticky balls) to terrifyingly broken (like All For One and his limitless ability to steal Quirks). This is easily ParanoiaFuel in itself considering the sheer range of Quirk users already introduced, like how one (who is thankfully a good guy) has the power to brainwash anyone who replies to him, and another (a genuine villain) has the power to disintegrate everything he touches.
** The latter even applied his power to his whole family ''by accident'', which also raises the question of how many accidents happened simply because a Quirk user was born with a power they couldn't control, or how often it's happened by now.
** Eri herself had a similar scenario with the one above -- by accidentally rewinding her father out of existence. By the end of her arc, she's ConvenientlyAnOrphan because her mother disowned her and her grandfather was in critical condition.
** Less horrifying, but still bad: Present Mic was born with his [[SonicScream Quirk]] active. How exactly did they manage to keep him from harming anyone until he was old enough to understand that his voice -- a baby's only form of communication -- hurt people badly enough to damage their eardrums?
* Hawks' mother had extra floating eyeballs as her Quirk, and she could see through all of them. Imagine running into her on the way home at night.
* Just the fact that there are superpowers in a world that once did not have superpowers is frightening. Dictators, religious extremists, and anyone who has no regard for the lives of others may have gained the upper hand. The fact that the series focuses solely on Japan mitigates the global implications of the possibility that terrorists and tyrannical systems gained superpowers. Just what is the world like outside UA?
** It is even worse to imagine what it was like when superpowers weren't in 80% of the population. Back when it wasn't even 10%, all it would take is one person with a powerful Quirk to have ambitions of personal conquest. All For One was subtle about it, but the odds that someone didn't try and take over a country openly with a powerful Quirk is highly unlikely.
** On another note, something that can be just as dangerous as one person with evil intentions is the public panic over who ''might'' be that type of person, and it's confirmed that the process of Quirks being accepted in society took years or even decades of strife (and even then, the fact that they gradually became more and more common likely had a hand in making them more accepted). It's ''very'' easy to imagine people with evil intentions, with or without dangerous Quirks of their own, stoking the fear of dangerous Quirk users to incite violence and oppression against people who have them, all the way up to outright genocide if it's combined with other forms of strife and bigotry real life humans would be more familiar with.
** While one hasn't been properly introduced yet and the other is only just being fleshed out as of June 2019, Gentle does mention two villains called Destro and Oji Harima, both of who are just as infamous, if not more so, than ALL FOR ONE! And Destro is said to be the leader of a group called the Quirk Liberation Army. Meaning this may well be a case of AscendedFridgeHorror (and it was).
** It's possible that Destro's more interested in removing limits on Quirk usage, but the 'Liberation Army' part does bring to mind a terrorist or some such organization.
** Both are true, as it turns out. The Liberation Army battled entire countries to reduce limits on Quirk/meta ability usage.
* While the observation that a lot of the heroes in the Top 10 have Quirks that are DifficultButAwesome can be a sign of good work, there is another possibility. All Might describes All For One going after strong Quirks when talking about the comparative weakness of his predecessors's base Quirks, and All For One would have been very active until very recently in canon. It is possible that the reason most of the Top 10 heroes either have really difficult Quirks, or fairly mutant Quirks, is that All for One would have stolen the powers of people with a lot more simple and powerful Quirks quickly. Further evidence is that a lot of the heroes highly ranked with more traditionally simple and powerful Quirks like Miruko, Kamui Woods, and Ryuku are 26 by around the time that All Might retires, putting their debuts at 20ish around the time All For One was presumed dead.
* When explaining to Midoriya why he's going through such rigorous training by cleaning up a beach, All Might says that if an unprepared vessel inherits One for All, their limbs would fly off and their entire body would explode. [[YouDoNotWantToKnow Uh, how exactly]] [[NoodleIncident does he know that?]]
** Perhaps it happened to one one of his predecessors, who tried to pass it to a weak person. After that, the knowledge was passed on to avoid repeating the same mistake.
*** Chapter 304 introduces the fourth user of One For All, Hikage Shinomori, who cultivated One For All for 18 years. In his final years, Shinomori's body began to rupture and passed away at the age of forty. At that time, Shinomori believed that this was because he did not train his body properly and so he likely passed down the advice that a decent level of physical fitness was a prerequisite to inherit One For All. Although decades after his death, Shinomori learnt the true cause of his death from All Might: RapidAging due to One For All leeching his life force. This drawback doesn't affect All Might or Izuku since they were born Quirkless.
** More likely than not, he was referring to when Midoriya used his powers for the first time. We see it breaks his bones, but if his body was any weaker, he probably would have completely lost the limb. Likely All Might is extrapolating from his own bone-breaking injuries when he was in training.
*** Nope. All Might confirms later on that he could use One for All at 100% right off the bat, without any issues, and that he isn't really sure why Midoriya's having so much trouble.
*** The reason why Midoriya is likely having trouble is because of a concept called "Quirk numbers" introduced in Two Heroes, and the doctor who turned out to be working for All For One. The ''same'' doctor that claimed Deku had no Quirk. Think about that.
*** Not quite. He diagnosed Izuku as Quirkless due to a) the failure of a Quirk to develop and b) the present of a pinky toe joint only present in Quirkless people. It's extremely unlikely the doctor stole Izuku's Quirk; he wouldn't have even come to see him if Izuku had been exhibiting a Quirk before that.
*** Reminder that the doctor himself diagnosed Izuku though (who, and I repeat, works for someone that ''steals Quirks''). He could be lying about Izuku's results (or maybe stealing ones Quirk regenerates a pinky toe joint, so he's dancing around the truth). The doctor lying and stealing his Quirk makes more sense than Izuku, for absolutely no reason at all besides "plot", is one of the remaining percent. Both of his parents have Quirks, after all. Also, what makes you think that he wouldn't have come to see him if he hadn't developed a Quirk before? He certainly WouldHarmAChild, [[https://deku-smash.tumblr.com/post/183467914620/so-we-know-that-the-doctor-who-diagnosed-midoriya after all]].
*** Just because something is unlikely does not mean that it cannot be true. Right now, the idea the Izuku had his Quirk stolen is mere fanon.
*** To add to that, Midoriya had gone there because his Quirk hadn't developed and, besides sudden mutations like that of Shigaraki, his theoritical Quirk should have been either his father's, his mother's or a combination, none of which look very useful and would fall among the more quirky Quirks that he isn't fond of stealing (hence why Best Jeanist is still in active). Midoriya developing a poweful mutation Quirk is just as likely as him being an atavist Quirkless, and the latter makes more sense given that, on one side, there is no way to know what a Quirk will be until it develops (so it would be the height of stupidity to steal an unknown that would most likely be a dud), when stealing a Quirk you cannot steal the control on it but you do steal the raw power it has developed (so it's way better to steal mature Quirks as opposed to dormant ones) and an hospital sees a lot of patients which could be targets for Quirk stealing, but the region doesn't seem to have a higher ratio of Quirkless kids, and on the other side it hasn't been mentioned that any of the unQuirked characters has had the bones growth (it may seem that's just an extra bone on the most useless appendage ever, but it's enough to cause discomfort when walking normally, which would have been mentioned).
%%% A little WMG here. *** There's more evidence pointing towards Izuku's Quirk being stolen beyond "because of plot". Both of his parents have Quirks, so Izuku being Quirkless does not make sense, and the doctor could easily be bullshitting the both of them. There's no real reason ''why'' Izuku shouldn't have a Quirk. Both his parents have Quirks so he should either have obtained his mother's telekinesis, his father's fire breath, or a mixture of both. Him having no Quirk seems counter-intuitive to the fact that Quirks are forcing humans to evolve, as evidence of humans having Quirks lies in their missing pinky toe joint, which would mean that the doctor faked the image. Unless he has some sort of Quirk-immunity (which as far as I'm aware, there's no evidence for this), again, this makes no sense. And again, he stole Tsubasa's Quirk (not confirmed, but obvious if you read the Tumblr link up above), so he has the means to actually do so.
* Endeavor and his wife did not have a happy relationship -- given how he only married her in order to produce a child strong enough to surpass All Might. She was absolutely aware of that. Knowing this, it doesn't take much to infer that he likely [[MaritalRapeLicense forced her into intercourse,]] just like he pushed her into a loveless marriage.
** [[FromBadToWorse It gets worse]] when you realize how Todoroki has three older siblings -- this means that Endeavor forced his wife to go through intercourse multiple times.
** His indifferent expression when telling Todoroki how his mother is in mental care also sadly makes sense. After having finally gotten the heir that he'd always wanted, [[YouHaveOutlivedYourUsefulness he couldn't care less about her]].
** A scary comparison to make: Endeavor basically sought out someone with a Quirk he wanted to mix with his own and had a kid who basically has both a Fire and an Ice Quirk. That isn't all that different from All for One putting a bunch of Quirks into someone to create a Nomu.
** It gets ''even worse''. With All Might retiring after his fight with All For One (promoting Endeavor to top hero by default in the process), it means that all the suffering that the family went through due to Endeavor and his obsession with producing a strong child ''ended up being AllForNothing''.
** However, much of what was assumed does not make sense given how the implications are they got married when Endeavor would only be likely ''twenty.'' Barring the far-fetched possibility that Endeavor was considering starting a family when he was just a rookie hero, this paints questions over a lot of this.
** As of now, Endeavor's abuse still isn't known to the public, something which his son Natsuo is particularly upset about. [[TruthInTelevision It calls to mind the many instances in real life of celebrities and other respected figures getting away with horrendous actions without being held accountable until years later, if at all.]]
** Though the latest chapters showcase that Enji and Rei used to love each other at first and that Shoto's siblings were not conceived through forced intercourse, the fact that Endeavour became the jerkass hero we knew by the time Shoto is five showcases how much of a SanitySlippage did Enji had over his rivalry with All Might.
*** Or due to the fraticidal rage and supposed death of the son he had been training before, given that it seems like comments about him weren't uncommon during the spartan trainings.
* It's shown that Kaminari Denki's electricity Quirk, if overused, shorts out his brain and turns him into an idiot for a while. His Intelligence stat is at 1/5 and he has the worst grades in Class 1-A. What if each time he overloads, [[PowerAtAPrice a little more of his brain is permanently damaged?]] What if eventually, one overload will permanently turn him into a vegetable? It certainly makes those [[PlayedForLaughs times his friends forced him to overload much more cringe-worthy to look at.]]
* In an Omake within the 7th Volume; a fan asked the author, Horikoshi, why the winged Nomu from the Stain Arc specifically picked out and took off with Midoriya. Horikoshi answered "''I will do my best to explain about Nomu later on''" -- along with a [[http://imgur.com/a/YnNv3 drawing of a boy]] seen in the very first chapter, as one of Bakugo's friends (and thus by extension acquainted with Midoriya), during childhood. [[TearJerker That boy's Quirk was having wings.]]

* When Izuku was little he thought of choosing a hero name similar to All Might's, who he always idolized, but when he grew older and had to choose a hero name he thought he is not worthy of it yet so he chose Deku with the meaning "Give it all." Basically, in order to achieve all the might he can have he has to give it all.
* There may be a more pragmatic reason behind Hawks' decision of giving Twice a chance to surrender, Hawks wants nothing more than to live in a society where heroes have more time than they know what to do with and he saw Twice as a perfect tool to achieve that dream. If Twice had chosen to surrender and allied himself with the heroes, he could lower the crime rate by creating clones of top-ranking heroes and thus give Hawks the freedom he always yearned for while in his perspective redeeming a man's broken life. No wonder he tried so hard to convince Twice to change sides!
* Overlaps with horror but Shoto has shown in multiple instances that while an expert at wielding his quirk, he has poor social skills. It is likely that Enji isolating him from his siblings and forcing him to train during his childhood stunted his people skills.
* Hilarious in hindsight as Shoto asked Izuku if he's All Might's secret love child. Later, we find out that Shoto is the product of a quirk marriage so he was asking based on experience. Dammit, Endeavor!
* A rather inspiring example: Keigo Takami's parents were desperate and cowardly people who spent their lives blaming others for their problems and using their Quirks to dodge the law. When he becomes Hawks, he registers his Quirk as "Fierce Wings", signifying his resolve to take life head-on.
* Of all of Bakugo's peers, despite being the weakest in terms of power Sero is the one least afraid to mock him and take advantage of his character flaws rather than ChildhoodFriend Deku, ClassClown Kaminari or manly Kirishima. This might seem weird but it fits his role as a Spider-Man expy.
* Now that Monoma knows One for All is a power ''stockpiling'' Quirk rather than a power ''generating'' Quirk, Izuku has the perfect excuse as for why it didn't "develop" until so late in his life. After all, how much power could he have reasonably stockpiled at age 4? It makes sense that a Quirk wouldn't express itself until it became viable as an actual ability, and would lie dormant until that point.
** This also puts into view the possibility of Quirks that manifest much later compared to the majority of the population. All Quirks work differently and operate on their own mechanics. As such, there may be several individuals whose abilities didn't become apparent until much later in life.
* Meta-wise, it makes sense that Horikoshi decided against making Izuku a straight out [[BadassNormal Quirkless hero]] and chose to make him the successor of [[BigGood All Might]]. Often, the powerset of the hero influences the style of stories one tells about him or her and the environment in which the story is set, two notable examples of this are [[TheCape Superman]] with [[ShiningCity Metropolis]] and [[TheCowl Batman]] with [[CityNoir Gotham]]. Had Horikoshi made Izuku a Quirkless hero, he would have been forced to compensate both in [[PoweredArmor equipment]] ''and'' [[PragmaticHero atti]][[AntiHero tude]] to keep up with the other heroes, impacting the tone of the story and making it more cynical and less hopeful, which was not what Horikoshi wanted. This can be noticed in the [[https://bokunoheroacademia.fandom.com/wiki/File:Prototype_Izuku.png prototype sketch]] of Izuku back when he was going to be a BadassNormal hero.
* For much of the early part of the series; Midoriya struggles with using One For All, injures himself in spite of having All Might's guidance, but then rectifies these issues once he trains with Gran Torino. All Might calls his instructing inadequate, but it's likely more complicated than that. Gran Torino states that Midoriya and All Might have contrasting personalities, but he also acknowledges that All Might figured out the Quirk much quicker than Midoriya did. It wasn't that All Might was bad at instructing Midoriya, he simply didn't understand the hurdles that his pupil was going through.
* The first person to pass on One For All had a latent Quirk that allowed him to pass it onto others. At first glance, it might seem like an [[AssPull incredibly convenient plot device]], considering how weak and unnoticeable it is. However, it's not that far-fetched at all, and in fact, makes perfect sense. As shown in-story, Quirks are hereditary, meaning that parents can pass on their Quirks to their children. His brother has the power to steal Quirks, '''in addition''' to the power to grant them. Him getting the latter Quirk, but not the former, thus makes complete sense.
** You could also say that this is why the later users of One For All can use their predecessors Quirks -- One For All is essentially ''stealing'' them for its own use. In truth, both All For One and his brother actually had a very similar Quirk its just that one had a crippling flaw that was only remedied by the unnamed power-stockpiling Quirk that he was given.
** The difference between the two 'twin' Quirks is best illustrated in the terminology used when they're adapting new Quirks into themselves -- AFO '''Absorbs''' Quirks, thus non-consensually stealing what others own and demonstrating total control over whom the targeted Quirk is granted to, OFA '''Assimilates''' itself into other Quirks, passively submitting itself to the will of the Quirk holder it transfers to, and bringing along the Quirk factor with it when it's voluntarily transferred to another, thus leaving control in the hands of the target the entire time. In truth, the power-stockpiling Quirk wasn't strictly necessary for Yoichi to create OFA with -- it merely allowed him to realise he did possess a Quirk of his own, once he assimilated a Quirk with a visible effect into his own existing Quirk, but he could have passed on OFA without it, though it wouldn't have had an effect until the Second Holder passed it on.
* While Bakugo's horrified reaction to Todoroki's reason for existing is justified by how disturbing it is -- another part of it could easily come from him seeing the kind of person he could turn into over his obsession with becoming Number 1.
** Also, his own Quirk is the merging of his two parents' Quirk into one that is much more powerful and 'heroic'. It was probably unsettling to him on a 'that guy's me but played for sinister' way.
* The name "One for All". At first, it might seem weird since it's actually a sum of many people's powers held by one person, suggesting that "All for One" might be a more appropriate name. However, taking into account [[AllLovingHero All Might and Midoriya's personalities]], it can be interpreted as "One person's power for the sake of All others". Also, it's a power that has been held by several people (with Midoriya being the ninth user).
** It ends up making perfect sense, when following TheReveal of "All for One" as the name of another Quirk -- one which enabled a powerful villain [[PowerParasite to selfishly hoard many other Quirks for himself.]]
** Also, it fits in that it's "One power for All people", in that it's a Quirk which can be freely passed on to anyone, from a Quirkless kid (Deku), to a person who has proven themselves worthy with their own Quirk (Mirio)
* Todoroki's costume completely covered his fireside with what looked like ice. Considering how he hates his father's fire powers, and vowed to never use that side of his in battle, this makes perfect sense; especially considering how he later gets another costume change, one more suitable, after having accepting his flame powers.
* So far in the series, we have plenty of confirmation of Midoriya being worthy of One For All as All Might's successor, especially based on how he rushes into danger if it means helping people. But there's also the fact that several of his classmates are starting to be inspired by him as well. Todoroki is motivated to get over his anger toward his father to better himself as a hero, Bakugo is encouraged to start working with others if it means winning, and even Mineta is able to get over his perversion and cowardice in order to win against a much stronger opponent on his own. Just like All Might was an inspiration and a symbol of peace to others -- Midoriya is starting to change a lot of people around him for the better.
** This ability to inspire people to do better was even seen at the very beginning of the series; when his reckless attempt to rescue Bakugo convinced ''All Might'' to defy his time limit, despite the risk to himself, and save the day.
* Aside from SuperSpeed and SuperStrength, One For All also apparently grants the user [[MadeOfIron Enhanced Durability]]. How does this happen? Simple. One For All's massive backlash punishes the user with extreme pain (broken bones being very common), but over time, this helps the user build resistance to massive amounts of pain. So, All Might being able to tank just about anything isn't inherently granted by the Quirk. In fact, it's a long-term by-product of his Quirk after years of wielding One For All.
* Uraraka's weakness; namely that overusing her gravity-cancelling powers, or applying said powers to herself (which ends up causing her extreme nausea), actually makes a great deal of sense. Nausea is a common symptom if in zero-gravity conditions. There's a reason why the aircraft used to train astronauts for zero-gravity conditions, are collectively called the ''Vomit Comet'', after all. When using this power of such a Quirk on herself, Uraraka is consequently then exposing her body to a zero-gravity environment.
* Bakugo telling Todoroki before their match at the Sports Festival that he'll "hold down his flames from above", since Todoroki had just started using them at that point. It's sounds slightly out of place, because he could have just said "I'll hold you back even if you use your flames". Why "from above"? Until we get to the last few seconds of their fight, and Bakugo pulls out Howitzer Impact, where he comes at Todoroki from above. Not only that, but the vacuum he made from using the move would have put out Todoroki's flames, so Todoroki putting them out himself from a traumatic memory took away a chance for Bakugo to prove himself to everyone that [[InferioritySuperiorityComplex he's as good as, or better than Deku]].
* Uraraka learning how to fight hand-to-hand seems like a suitable skill for her to learn to enhance her offensive capabilities. In what we've seen so far, though, this mostly seems to be limited to grappling and submissions. However, considering that Uraraka's Quirk allows her to reduce an enemy's weight to nothing, it's no wonder that grappling would be a fantastic fighting style for her.
* Tsuyu's unusual face, namely her big wide eyes, solid oval pupils, and a V-shaped smile, is yet another frog reference: She resembles the Creator/{{Sanrio}} mascot Keroppi. This also ties in to her chosen hero name of "Froppy".
* Shinso has MindControl as a Quirk. On the surface, it certainly seems like a [[BadPowersBadPeople power only villains should have]], but he'd be really good at beating whole hideouts full of villains by just kicking in the door and shouting pretty much any phrase that comes to mind. Whether he says [[PreAssKickingOneLiner "Your criminal days are over!"]] or [[TheGadfly "Did anyone order pizza?"]] doesn't matter; the instant everyone in the hideout yells, "Get 'im!" Shinso wins.
* One thing that's pretty interesting about ''My Hero Academia'' compared to other Shōnen series is that the arcs are very fast-paced: as of this writing, eight volumes have been published with a ninth coming soon, and each one roughly covering one whole arc (cliffhangers notwithstanding). This isn't just Horikoshi being good at pacing arcs, it's a reference to Superhero comics usually being collected in trade paperbacks, with one roughly complete arc collected into a roughly standalone volume!
* Todoroki [[LikeFatherLikeSon is more like Endeavor than he realizes]], in that in most of the competitions and exams ''he's ranked second.'' Second in Aizawa's Quirk evaluation exam, second in the sports festival, and second in his first term final exam. And with the introduction of Inasa, he's most likely ranked second among those who took the recommended student exam. He's even ranked second in the popularity poll!
* When Kaminari describes Bakugo's personality as being like "crap steeped in sewage" it's not just a colorful simile. Soaking feces in urine is an old method to produce saltpeter, an ingredient in gunpowder.
** Bakugo is also very likely to have ''intermittent [[StealthPun explosive]] disorder'', a behavioral disorder characterized by explosive outbursts of anger and violence, often to the point of rage, that are disproportionate to the situation at hand (e.g., impulsive screaming triggered by relatively inconsequential events).
* Camie didn't get the usual square with her name and Quirk during the first License Exam Arc because we didn't meet Camie.
* Overhaul keeps talking about illnesses and cures in his first appearance. It's quiet befitting of his [[PlagueDoctor theme]].
** Almost a GeniusBonus: They are first shown burning the car of those they consider ill; it was common for the doctors to burn the bodies of bubonic plague victims.
* In a flashback we see Mirio with a ponytail while in the present he has short hair, His suit is made with his hair woven in, It probably just hasn't grown back fully yet.
** Alternatively, the ponytail was specifically BECAUSE he was growing his hair out for his suit, and needed a way to keep it from getting in the way.
* In the first page of Chapter 117, as Midoriya and Bakugo leave the dorms at night, we see four students asleep in their rooms, Iida, Todoroki, Yaoyorozu, and Kirishima. Though it may appear to be simply a random group of students sleeping to demonstrate how late it is, they are also the group of students that went to save Bakugo during his kidnapping. Given the content of the chapter, it could serve to highlight Bakugo's character development throughout the series so far.
* They say you subconsciously find romantic partners with similar traits to your mother. In Izuku's case, his mother happens to have gravity-related powers. Guess who the primary love interest's powers involve?
** Adding to it is that Ochaco looks a little bit like Inko when she was young and thin, mostly with her haircut.
*** Adding to that, Ochaco is somewhat chubby as well. Not saying Midoriya is a ChubbyChaser, but...
** Same goes for the opposite with similar traits to the father. Izuku's father's related to fire, as is his rival.
* Why doesn't All For One steal every single Quirk he can get his hands on? Because doing so would actually be detrimental to him. Quirks like Best Jeanist, Edge Shot, or Mirio's require intensive training to use at their full potential. Taking Quirks like theirs would just be a waste of time, seeing how long it would take to use the Quirk at its best. And then there's Quirks that either permanently mutate the user's body, like most animal-related Quirks, or are too dangerous to have, like Overhaul's Quirk. The best Quirks to steal, therefore, are simple yet incredibly useful Quirks like Ragdoll's or Quirks to later give to a Nomu.
** Furthermore, it's later revealed in the manga that All For One's ''Quirk'' maybe be able to steal Quirks theoretically without limitations, but the user's ''body'' can only handle so many Quirks before starting to undergo a SuperpowerMeltdown, especially as Quirks themselves are starting to get stronger and more powerful as the generations pass, whereas All For One still possess the body of a first-generation Quirk holder. This provides a hard limit on the amount of powers he can store and hoard before he needs to pass on some of them to prevent his body rupturing from the strain. In addition, the number of Quirks he can safely withstand at once went down after his body got ravaged at All Might's hands, further limiting the immense power he can bring to bear, despite being able to theoretically use any power in existence. In addition to that, its further implied that All For One's lifespan, whilst extended through the particular Quirks he's been able to acquire over the years, isn't infinite, and will eventually run out, hence why he's so focused on creating a 'successor' for the new empire of evil he wants to build atop the rubble of modern Japan. He cannot afford to waste valuable time mastering tricky Quirks whilst his plans are in motion. Of course, All For One being [[ItsAllAboutMe the kind of person he is]], said successor is basically a [[BodySurf carbon copy of himself with a younger body]], and has been further enhanced to store more power than his original self could, rather that truly bequeath anything he's accumulated over the years to another person.
* Some of the teachers like Aizawa and Midnight seem somewhat out of place in a class setting teaching kids, but something to consider is that a lot of heroes are fairly active during the day. Aizawa is stated to do a lot of his hero work at night, and it's likely a similar story with Midnight. Thirteen is a rescue worker, who would mainly be active during disasters, so it's possible a lot of the teaching staff was hired from a pool of heroes who aren't active during school hours.
** It also explains why Aizawa is perpetually exhausted looking and sleeps in his classes a lot. The guy probably doesn't get much rest considering how much of his fighting style emphasizes heavy martial arts mixed with his eye straining Quirk. Conversely, Midnight being generally better off can be easily explained by her Quirk enabling her to subdue criminals more easily without needing to resort to extreme movement and combat, and her preference for non-fatal/physical methods and friendlier disposition (as is shown in both the series and ''Illegals'') likely means she tends to finish things pretty quickly and with the villains probably either surrendering non-violently, thus giving her more time for rest.
** It's also likely to ensure that heroes in training get exposed to a lot more types of heroes than the flashiest on the street. Why have a kid who has the potential to operate at night or as a rescue hero get exposed to only street heroes after all.
** Given that they are teachers at a school filled with super-powered teenagers, one of the most important considerations is the ability to control the students. Both Midnight and Eraser Head have powers that can immediately end potential conflicts between students or any other incidents painlessly. These two in particular are also skilled in restraining opponents also without direct harm (well, non-consensual harm in Midnight's case). Combined, their powers and talents make the two ideal for teaching classes and instilling discipline on young, sometimes-defiant, heroes-in-training even with their [[BunnyEarsLawyer personalities]].
** Notably on the idea of controlling the students it is the teacher who can deactivate Quirks on sight who is put in charge of not only the most aggressive student (Bakugo), but also arguably the most powerful student when it comes to raw Quirk power (Todoroki). It's fairly likely that choice was deliberate. Most of the students with self-destructive Quirks, like Kaminari, Aoyama, Tokoyami, and Midoriya, are also in his class, which would make sense -– if they get out of control, like Midoriya with his early Quirk and Tokoyami in the Training Camp arc, he can manually shut them down.
** Also note the other teachers: Present Mic can get everyone's attention in a hurry, Ectoplasm can have a clone instruct a student one-on-one, Cementoss can separate students quickly, All Might can physically stop someone fairly easily regardless of their Quirk, and Vlad King can hold back students with his blood. EVERY teacher we've seen directly teach the first year classes in the hero course has something their skillsets and Quirks can do to handle 20+ superpowered students at once without hurting them; other teachers, like Snipe and Thirteen, haven't been shown doing more than helping with specialty classes with another teacher present, and likely teach the higher classes who have already been trained to handle their Quirks and tempers a little better than the first years.
* Tiger stands out quite a bit from the other Wild Wild Pussycats, who are quite girly. He's revealed to be transgender, implying he joined/founded the team before transitioning.
* The second anime opening shows Todoroki stretching alone in a dark place, soon after, however, the clouds above the sun move and the place where he is becomes bright, this foreshadows the fact that the Sports Festival Arc is a turning point to a brighter time of his life, he manages to reconnect with his mother, start dealing with his trauma over his father and even befriends Midoriya.
* Stain reducing Todoroki's ice to chunks with a battered katana and his ability to shake off a 5% Smash from Izuku's Full Cowl despite his Quirk having no apparent strength-enhancement might seem like a case of CharlesAtlasSuperpower, but given the nature of Quirks and how they can combine as they're passed down from parents to children, it's entirely possible that his Quirk could be a hybrid with some sort of physical enhancement from somewhere in his ancestry. This might also explain why some characters have odd appearances that seem unrelated to their Quirks -- for example, Koda of Class 1-A looks like a rock monster but his Quirk is talking to animals, and Tokoyami's bird head seems to have no connection to Dark Shadow other than the aesthetic. This could mean that their Quirks are technically hybrid Quirks that present secondary/vestigial characteristics from their ancestry.
** This could be the same reason Aizawa seems to have a minor antigravity Quirk that makes his hair levitate when he's using his Quirk. It only works when he's activated it, and since his actual Quirk is centered on his eyes, so is this one.
* Several of the locations in MHA have their names derived from planets in Franchise/StarWars. A lot of them have meaning when you look at the events that occur there:
** Tatooin/Tatooine Station: A train station Midoriya and Bakugo's hometown, and one of the first named locations seen in the series. Tatooine was where Luke Skywalker's HerosJourney began.
** Orudera Junior High School: Named for Alderaan, Princess Leia's home world. Midoriya and Bakugo go to school here before being admitted into UA High. Destruction of something precious (Midoriya's Notebook) leads to a great change in the narrative.
** Dagobah Municipal Beach Park: Named For [[Film/TheEmpireStrikesBack Dagobah]], where Luke Skywalker's TrainingFromHell with Yoda takes place. Midoriya undergoes similar training so he can inherit One For All.
** Nabu Junior High: Named for [[Film/ThePhantomMenace Naboo]]. Hitoshi Shinso went to this school before attending UA. In ''Episode I'', Naboo is blockaded by the Trade Federation, referencing the obstacles Shinso was unable to overcome, not being admitted to the Hero course due to his Quirk not being suited for direct combat.
** Hosu, Tokyo: Named for Hoth. In ''Star Wars'', the Battle of Hoth was the result of an ambush by the Imperial army, after discovering the Rebel Alliance base there, and the Rebels lost badly. In much the same way, Stain loses due to an ambush by Iida, Midoriya, and Todoroki, and the city is almost overrun by an attack from three Nomu.
** Kamino Ward, Yokohama: Named for [[Film/AttackOfTheClones Kamino]], where the Clone Troops were grown. Similarly, Kamino is where All For One was growing Nomu to use in attacks carried out by the League of Villains/Villain Alliance.
** Musutafu: Named for [[Film/RevengeOfTheSith Mustafar]], the site of Anakin Skywalker and Obi-Wan Kenobi's last battle. Bakugo and Midoriya's hometown, as well as where UA is located; possibly a reference to the bitter rivalry between Bakugo and Midoriya.
* Todoroki and Yaoyorozu were admitted by recommendation, meaning they didn't have to take the entrance exam. Both of them have Quirks that would make it difficult for the tests to function properly if they were participating. Yaoyorozu's cannons would be potentially lethal if another student got in her way, and Todoroki would makes whole streets inaccessible with sheets of ice. Had they been present, they would have been bigger hazards to other test-takers than the robots, so they were allowed to skip the exam.
** This is also true of at least one of those from Class B who were admitted the same way. Honenuki's softening ability could render the entire battlefield, or at least parts of it, very hard to maneuver, and could lead to drowning or suffocation if anyone was caught under any wreckage and he didn't notice.
** Tokage, the fourth recommended student, would have been very at risk through splitting up if other students didn't notice her scales and attacked indiscriminately.
** Yaoyorozu must have had a different exam pattern though, considering she doesn't have any kind of "high speed movement object" which could have helped her in the race.
* During the cavalry battle, Hatsume is eager to team up with Midoriya, who's huge point value scared everyone else away. We learn later in her fight with Iida that Hatsume isn't trying to win, and only cares about drawing attention to her inventions. No wonder she jumped at the opportunity to be on his team.
* Iida in fact was the one to defeat Stain; Stain was knocked unconscious due to a broken rib puncturing his lung. This injury could only have been dealt by Iida's kick to the chest. So even though it seemed Stain was knocked out by a CombinationAttack leaving him open to a finisher from Todoroki, Iida was the one that actually brought him down. Fitting since he has the most personal tie to Stain.
* Mineta's attempt to spy on the girls in their locker room actually kind of worked. Jiro's earphones are shown to be extremely sensitive, and she plays with them constantly. Her stabbing Mineta in the eye was actually a moment of extremely intimate contact, just not in the way he was hoping for.
* Although the story provides a reason for why some were paired, the final exam matchups have more than just simple attempts to fix the weakness' of the students Quirks, but also help them improve in other ways.
** Kaminari and Mina are put together at the End Of Term against Nezu. The reason why they failed was simple: The two BookDumb characters of Class 1-A were put together to fight against a character with an Intelligence Enhancing Quirk and from the looks of the battle, it's clear they weren't even able to understand that the point of the test was outsmarting Nezu, rather than fighting him. It was obvious they wouldn't pass, because they didn't even get the assignment.
** Kirishima and Satou both have Quirks that increase their physical strength and body but run on a timer of sorts, with Kirishima being more of a StoneWall fighter, and Satou being a LightningBruiser who loses his intelligence due to the sugar he eats. Their opponent was Cementoss, whose Quirk allows him to manipulate concrete and cement. Cementoss used his power to create barriers that were easily replaceable, forcing Kirishima and Satou's frontal assault into a battle of attrition that neither could win due to their time limits. The idea behind their fight was to prod them into fighting tactically rather than going WhenAllYouHaveIsAHammer and having Cementoss hard counter them. And while Satou has an excuse in that his power makes him think less clearly, Kirishima does ''not'' and could have at least tried to create a strategy for himself and his partner to follow.
** Tsuyu has a WeakButSkilled Quirk that gives her all the powers of a regular frog, just for a human to use. Tokoyami has a UnskilledButStrong Quirk that has a lot of raw power to it, but very little control over. The entire point was to show Tokoyami that Quirk's are not always needed to fight and can be supportive, while Tsuyu is pushed to play the support role to someone whose Quirk doesn't have good synergy with her. Naturally their opponent is Ectoplasm, whose Quirk can create copies of himself that, while weak, can still close the gap and get into close combat with the FragileSpeedster and the SquishyWizard, plus he can make larger copies that are more powerful than the others. His Quirk allows him to be both WeakButSkilled, and UnskilledButStrong at the same time, forcing both students to learn when offensive power is important, and also show when supportive power is needed.
** Toru and Shoji both possess utility Quirks that are a great help with intelligence gathering and stealth, but don't give them much direct combat strength. Naturally they fight Snipe, a hero whose Quirk is the ability to manipulate the trajectory of his bullets, allowing him to both be strategic, and offensive at the same time. Since neither Toru or Shoji can hope to win in a fight against him, they both have to use their Quirk's ability to be strategic to outsmart Snipe. Notable their plan works because early on, Toru stayed close to Shoji, allowing Snipe to keep track of the two because Toru couldn't really well separated from Shoji, but because Shoji created a distraction, Toru was able to sneak around and nab him.
** Iida and Ojiro both have Quirks that increase their physical mobility and strength, so naturally they fight Power Loader, whose tunneling Quirk negates the biggest strength both of them have. Iida is faster than Ojiro but his movement is more rigid and mostly in a straight line, which means he cannot run across the battlefield because he'd fall into a pit. Meanwhile, Ojiro isn't as fast as Iida, but he has better mobility when it comes to dodging and isn't limited by one direction. At the same time, he can't move fast enough to the exit since Power Loader is tunneling too fast for him. Naturally the strategy they use to win is to use Iida's speed advantage to move Ojiro in such a way where he gets enough of an advantage to move quicker to the exit, which works out in the end.
** Koda and Jiro is a bit more straightforward, as both are sound based Quirk users, so they fight Present Mic. Koda's Quirk allows him to speak to animals while Jiro can use her headphone earlobes and heartbeat to create blasts of sound that are very powerful. The entire point of the test was not to see if Jiro was strong or weak, but more to see if Jiro could get Koda to break out of his shell and use his Quirk without his shyness getting in the way of the situation. Present Mic could easily negate Jiro's Quirk and any of Koda's weaker attempts at using his Quirk, so pushing him to be loud was the only way to win, and Jiro managing to do so is how they succeeded.
*** Adding onto this, Present Mic spends most of the match screaming incredibly loudly. And since most animals are afraid of loud noises, the first time he did this would have likely scared away most of the naturally diurnal animals in the forest. Forcing Koda to really step up his game and use his communication with living things outside his normal purview.
** Uraraka and Aoyama are put against Thirteen, which seems weird at first, but their Quirks are easy for Thirteen to counter. Aoyama needs to stand still for a moment to fire his navel laser while Uraraka needs to physically touch something to manipulate its gravity. By trying to suck them up, Thirteen makes it too difficult for them to do either and pushes them to try and find ways to get around it. It's worth noting that Aizawa says in the next arc they barely passed, which makes sense as the only reason they passed was Aoyama bringing up Uraraka potentially crushing on Midoriya, causing her to let go in surprise and Thirteen to cut off her Quirk of fear for the students' safety, allowing Uraraka a completely accidental opening to get the cuffs on her. Another aspect that is not used in the story was that both have Quirks that cause them illness, so it's possible the goal was to have them somehow beat Thirteen before they overtaxed themselves.
** Sero's Quirk allows him to make tape, while Mineta can make sticky balls. Since neither of them have Quirks outright designed for actual combat, Midnight, whose Quirk isn't suited for combat, makes logical sense. Furthermore, personality wise, Mineta is a pervert who gets DistractedByTheSexy, while Sero is the GenericGuy who has on multiple occasions [[WhatTheHellHero called out]] Mineta on his perverted behavior. Naturally, MsFanservice Midnight is the best opponent for the two since if the two can pass, it proves they have matured. Sero and Mineta also fight mostly by immobilizing their opponent, which won't mean much to Midnight because she doesn't have to move to activate her Quirk, and can just stay by the entrance and use her KnockoutGas against anyone who comes too close.
** Todoroki and Yaoyorozu are matched against Aizawa because both of them have Quirks that are so powerful and versatile that both tend to depend on them above direct combat. Aizawa presents an opponent who can rob them of their greatest strengths and easily overcome them both in physical combat and mobility. To defeat or escape him, the two would have to use their Quirks in more creative manners and use each other's abilities to their fullest. In addition, because of the nature Yaoyorozu's Quirk, they just needed a moment to devise a counter to Aizawa and they would be able to win before the battle even began, as even if their Quirks were erased, Yaoyorozu's items would still be there for her to use.
** Midoriya and Bakugo were paired against All Might to help fix their personal issues. Bakugo is StrongAndSkilled with his only real flaws being his {{Pride}} [[HairTriggerTemper uncontrollable temper]]. Midoriya's strong, but he also has a tendency to avoid direct confrontation and is a bit of an ExtremeDoormat to Bakugo. All Might is strong enough that neither can defeat him on their own, and (as Bakugo points out) fast enough that they can't just escape without fighting him. If Bakugo continued to abuse Midoriya and refuse to work with him, and if Midoriya kept retreating and refused to stand up to Bakugo, then they would be easy prey for All Might. Their powers (which are actually fairly good all-around) were a bit of an afterthought, but considering that they're the two most well-rounded and powerful students in the class, it made sense to pair them with a very well-rounded and powerful hero, especially considering that All Might is likely the only teacher who could have stood up to a full-force attack from the two of them anyway (barring Aizawa erasing one of their Quirks, which would leave him open to the other).
* At the end of Jiro and Koda's exam after defeating Present Mic, Koda is shown [[BridalCarry carrying]] Jiro through a gate. Why? Mic's screaming ruptured Jiro's eardrums, which would make her dizzy and affect her balance, so Koda carried her so they could make it through the gate before the timer sounded.
* The perfected Quirk-destroying bullets rewind peoples' bodies to a state from before humanity ever developed Quirks, removing their Quirks permanently. This probably means that the prototype bullets rewind peoples' bodies to a state from before they, personally, developed their Quirks, so it always comes back after a while.
* A potential reason Izuku was born Quirkless: as a recessive trait it is likely it a trait carried on chromosomes. Many traits in real life life like that are present in non-affected people, but those who are carriers. They'd be noted as Qq, with the Q being the dominant trait and q the recessive. Izuku's mom and dad likely were both carriers, and as a result Qq crossed with Qq. Thus 25% Quirk with non-carrier for Quirkless, 50% Quirk with carrier for Quirkless, and 25% Quirkless.
** Quirklessness being so rare is also explained by this. While Quirks were originally shunned, nowadays a flashy Quirk can be attractive, so it chokes out the recessive q gene. Let's use Todoroki as an example (Bakugo would also work, as he has combination of his parents' Quirks): he's obviously a QQ carrier, carrying both of his parents' dual-dominant Quirks. If either Endeavor or Rei were Qq, either Fuyumi, Natsuo, or Toya likely also ended up Qq, but Todoroki's parents kept pushing until they had a QQ child. Now, any child Todoroki has can't have the recessive qq, since Todoroki himself doesn't carry it. Now consider how common Quirk marriages used to be, and you realize that there's been an intentional flooding of QQ people into the world, which overpowers the odds against both qq and Qq people. Quirklessness may never be eradicated, but there's certainly been a concentrated effort at reducing it.
** This isn't necessarily incorrect, but its an oversimplification. [[spoiler: Toya Todoroki was born with parts of both parents' quirks: his father's flame and his mother's ability to tolerate cold temperatures.]] This shows its not as simple as getting a quirk gene or not getting one. Shoto avoided this problem by essentially having one quirk on each side of his body.
* A minor one, but at the start of the Final Exams arc, we see [[BookDumb Mina and Kaminari]] complain about Mineta being ranked 9th in the classes' grades since they thought he was "one of them" (a.k.a. they thought he was a slacker like them as well). That being said, he is actually a bit of a slacker; despite the fact that he has the highest intelligence stat in 1-A (tied with Yaoyorozu and ahead of Midoriya, Iida, and Bakugo), Mineta's grades are lower than those of Ojiro (Ranked 8th), Jiro (7th), and Tsuyu (6th)!
* During Midoriya's battle with Chisaki, Nighteye's Quirk predicted that Izuku was going to die by the end of it, but that didn't happen. At first this seems to be a typical Shōnen cliche about how TheHero [[ScrewDestiny is in charge of their destiny or some crap like that]], but there's a perfectly rational explanation (as rational as the world of MHA will let it be): Eri. Her Quirk allows her to "rewind" people to a certain point, even erasing them from existence entirely! And Izuku was carrying her during the end of the fight. He likely knew that Eri's Quirk would prevent the future of him dying in that battle. It also helps that Eraser Head showed up when Eri's power was starting to overwhelm her.
** Actually Nighteye's Quirk seems to have a pretty big blindspot, it predicts the future of its "target" but it doesn't take into account the actions of other people; for example he says "Chisaki will kill Midoriya and flee with Eri" but this is just relative to Deku and doesn't assume any action on Eri's part. It seems he "loads" the odds of his visions with his biases (subconscious or otherwise) because he just sees Eri as a victim to be rescued and not a catalyst for victory.
* It makes sense that Nighteye was going to die. Since all his visions happen 100%, and only he saw the vision of him and Deku dying, while everyone else fought to save Eri he gave up and stuck to the future he saw.
* A possible reason why Mic and Aizawa are shown to be friends despite their conflicting personalities: both of them are shown to be very intelligent. It's possible they were able to appreciate each other simply for being people they do not have to talk down to.
* Why is Recovery Girl one of the people who knows All Might's secret? Well, who else could he go to for all those surgeries?
* The reveal that Camie's Quirk makes her a MasterOfIllusion further serves to make her a perfect fit to be replaced by Toga, as she could have passed her shapeshifting off as illusion to Camie's classmates.
* Why did Nomu block Izuku's smash against Tomura without being prompted, when every time prior he had to be ordered to do something? Because he was ordered by All for One before the villains came to protect Tomura from any attack made using One for All.
** In addition to this, when All Might and Izuku talk before the Sports Festival, Izuku comes to the conclusion that the reason he didn't break his arm attacking Nomu was that it was his first time using One for All on a person, and he subconsciously put the brakes on. His original target for the punch being the much more frail looking Tomura gives another reason why the brakes were put on.
*** Also fridge brilliance in that Izuku notes that the reason his bones shatter from using One For All usually isn't the blast itself, but the shockwave that radiates through his body afterwards. That's why he can charge up [=OfA=] with no problem before releasing it, and it's why his braces and his iron soles are so useful -- they also blast the kick back out for two separate attacks. If the Nomu absorbed the shockwave from [=OfA=] the way it did All Might's punches, there wouldn't have been anything left to radiate through his arm and destroy it.
*** Going further with that point, each time Deku is using Full Cowl is basically "sending the shockwave through his own body to power up". Which is actually why he feels pain when using higher percentages even while he is just standing in a place. The "focusing the power in one point" technique doesn't cause that unless you release the power upon impact since he is just reuniting energy. Using Full Cowl, however, can be harmful, since he is not only channeling power but also releasing it at the same time.
** Tomura does order the Nomu to block it, at least in the manga. In the anime we're focused on Midoriya too much during that moment to hear what Tomura may or may not have been saying at the time.
* With the unsettling reveal that Aoyama is stalking Deku, we know something unpleasant is in the air. It means that a character obsessed with bright and shiny things... has a hidden [[DramaticIrony dark side.]] Sneaky Horikoshi!
* Aoyama struggled to place 42nd in the first event of the Sports Festival and we saw him in a lot of pain after the race, coming in last among the cutoff point. In Chapter 168, he explains [[PowerIncontinence ever since he was little his Navel Laser has been painful to use without a support belt because he suffers power leakage problems while using his Quirk]]. He really was at a disadvantage.
* Izuku fighting against Gentle with the reveal of Gentle's Quirk is actually a very worthwhile test for Izuku. Gentle's Quirk allows him to make anything elastic and bouncy... ''including the ground below them and even the '''air''' in front of him.'' This means most brute force or offensive tactics will not work on him and push Izuku to do better, especially now that with the focus on long-range combat.
* The collaboration between ''My Hero Academia'' and the ''Franchise/MarvelCinematicUniverse'' to promote ''Film/AvengersInfinityWar'' focuses on trailers which show that All Might and Class 1-A idolize (or in Bakugo's case, begrudgingly respect) the Marvel heroes, especially given certain parallels between some of the comparisons (Deku notes that Captain America was once powerless like him, but never gave up to fight for his heroic ideals, for example). This works on multiple levels:
** The United States is credited in-universe as the birthplace of superheroes -- obviously a ShoutOut to said country being the homes of Marvel and DC, the two companies which [[TropeCodifier formed the foundation]] of superhero fiction, which ''My Hero Academia'' takes heavy inspiration from. Not to mention, many of their heroes obviously being American as well, barring exceptions like Black Panther, Thor, and Star-Lord's alien teammates from the Guardians of the Galaxy. All Might in particular is a very "golden age"-esque classic style American superhero: a blonde haired, blue eyed, musclebound stud with a chiseled smile blowing away every enemy in his path.
** The Class 1-A students are teenagers who grew up in a universe which reveres the hero profession, and are heroes in-training themselves who look to older pros for inspiration. Many of the Marvel heroes are adults or at the very least, in the case of heroes their age like Spider-Man, experienced crime-fighters themselves and have gone through a lot more than their U.A. counterparts[[note]]To compare, many of the fights shown thus far in ''MHA'', including All for One's reign of terror in the past, have always been localized within Japan. ''Infinity War'' shows that the Avengers and the Guardians of the Galaxy are set to do battle with Thanos to prevent half of humanity (and the universe) from being wiped out, and that is still without pointing out how many other times the world has been threatened in previous movies or even the more outrageous events that take place in the comics, to further display the massive gap in power between both franchises[[/note]]. There's also the massive difference in how long both franchises have been around: ''My Hero Academia'' began publishing in 2014, nearly 6 years after the MCU began with ''Film/IronMan'' and more than several decades after many of their heroes made their debuts in the comics proper.
** One main source of conflict in ''My Hero Academia'' is whether a hero must choose whether ToBeLawfulOrGood; people like Izuku and Shouto recognize that doing the right thing at times means breaking their universe's pre-established rule that Quirk users must be licensed to use their powers in public, and vigilantes are frowned upon despite their intentions. Such a struggle formed the basis of ''Film/CaptainAmericaCivilWar'', which delivered good arguments for both sides of the conflict, and outlaw heroes in the Marvel universe tend to be treated a lot better than their ''Academia'' counterparts. Even the Avengers could be considered as a Hero Agency in the ''Academia'' universe, with Spider-Man outright calling his crime-fighting activities [[Film/SpiderManHomecoming an internship]] akin to the ones done by U.A. students.
** In something which overlaps with FridgeHorror, Shigaraki takes the place of Thanos in the ''MHA'' version of the poster. His Decay Quirk allows him to disintegrate everything with the touch of his fingers, much like how in the end of ''Infinity War'', Thanos ends up disintegrating half of the universe with a snap of his fingers after completing the Infinity Gauntlet.
* Towards the end of the anime's third OP, ''Sora ni Uteba'', we see scenes of Class 1-A taking their exams. Several of these scenes serve as {{Foreshadowing}} to the circumstances of the exams.
** Tokoyami and Asui are both in positions that suggest they've just landed from a great height (and we even see Tsuyu land on-screen). The majority of their exam involves them trying to escape from Ectoplasm by using their Quirks for their mobility.
** Satou and Kirishima both have Quirks based on brute strength, but neither are fighting at full capacity -- Satou's Quirk makes him dumber the more sugar he eats, and only Kirishima's arms are hardened, when he can cover his whole body. They're not using all of their resources in the face of a stronger opponent, so it's not going to end well.
** Uraraka's face takes up several frames when she and Aoyama show up, indicating that the exam will focus mainly on her realizing she has feelings for Deku, while Aoyama takes a backseat.
** Shoji is shown with several of his Dupli-Arms turned into ears and eyes, indicating that he and Hagakure have no idea where Snipe is, and their exam is going to focus on avoiding, locating, and subduing him.
** Kaminari and Ashido are the only duo to have a high-angle shot of themselves, implying that Nezu is looking down on them; indeed he is, both literally and metaphorically. Not only is Nezu in a crane destroying the city they're in, but they're the two lowest-scoring students in the class, and Nezu's Quirk is literally AmplifiedAnimalAptitude. They're also looking away from one another, whereas all other groups have them moving and/or looking in the same direction or at each other, implying they're clueless as to how to beat Nezu.
** Yaoyorozu is alone, but looking resolute, preparing to use her Quirk; by this point in the exam, Todoroki had been captured and suspended over a bed of caltrops by Aizawa, and Yaoyorozu is finally getting over her self-confidence issues.
** Sero's tape is seen blatantly across Mineta's face in their exam shot, before it retracts into his arm; Sero is incapacitated for most of the fight, but Mineta places his tape over his nose and mouth to avoid getting KO'd by Midnight. Also, Mineta takes a pose that implies he's going to grab onto something, and considering what Midnight's [[{{Stripperific}} main identifying trait]] is, and Mineta's personality, you know what he's thinking about.
** Iida and Ojiro's exam shows only the latter, flying above several holes in the dirt. To clear their exam, Iida uses his engines to "throw" Ojiro into the gate while getting buried himself, explaining why he's off-screen.
** Jiro and Koda are the easiest to spot -- the wind blowing through the grass represents the volume of Present Mic's Quirk. However, Jiro also has one ear covered, possibly to stop the bleeding that results from Mic's Quirk damaging her eardrum. Koda's bringing his hands towards his mouth either as a show of nervousness, or as he's preparing to speak to the bugs and beat the exam.
** Bakugo, sans Izuku, flies through the air with his explosion Quirk, his red-hot hand coming into contact with the camera. This represents a point where he breaks away from Izuku to attack All-Might on his own.
*** The lack of Izuku, Todoroki, and Iida in their respective exam shots also serves to create suspense as to whether or not they make it out of the fight with Stain.

* While he'd never admit it aloud, some part of Todoroki instinctively knew that he should stick to ice on Bakugo. After all, when your opponent's Quirk is sweating nitroglycerin, do you want to surround him with ice to lower the temperature or do you surround him with fire that logically should give him a power boost? Or, inversely, [[LudicrousGibs blow up Bakugo to bits]] [[HoistByHisOwnPetard with his own sweat set on fire]], [[ThouShallNotKill which Todoroki really don't want it to happen]].
* Yaoyorozu (whose Quirk allows her to create any inanimate object that she knows the molecular composition of) mentions that it's against the rules for people to use their Quirks to manufacture products, especially money, as it would disrupt the economy. Being a SpoiledSweet {{Ojou}}, it stands to reason that her family likely capitalized on the Creation Quirk in previous generations, before laws could be implemented to regulate such things!
* While Yaoyorozu's costume may seem to be mostly for fanservice, the design and what it shows actually make sense given her Quirk. Her Quirk allows her to make inanimate objects from her body fat. Her costume is a leotard which exposes her arms, legs, and part of her stomach. These areas of the body tend to have some of the largest fat deposits.
** It is also stated that she was intending to make the costume even more revealing than it was but wasn't allowed to due to the rules on modesty (no doubt thanks to women like Midnight). This implies that she was originally planning to employ her rather large breasts in combat due to their high fat content as it is hard to see where else on that costume she could gain an advantage by losing any more fabric. Its also possible of course that she may have been discouraged to do so by the fact that she would have gone down to an a-cup each time which sounds rather painful.
* Class 1-B's School Festival idea is a play that manages to be a strange mash-up of ''Literature/TheLordOfTheRings'', ''Franchise/StarWars'', ''Theatre/RomeoAndJuliet'', and ''Franchise/HarryPotter''. The idea is suggested to have come from Monoma, which makes sense when you realize that the guy whose Quirk is all about copying other people's Quirks can't come up with anything original.
* Endeavor's reverence for All Might's position seemed strange. It should be merely a slight increase in standing, but he treats it as an impossible gap to cross. When he gets it, it brings nothing but misery to him. Partially because he didn't technically earn it, but mostly because he knows he can't fill the position like All Might did. Why the obsession over a simple number? Because it's not just a number. The ranking system we see in the series is supposedly only used in Japan and not recognized by other nations, but All Might is repeatedly referred to as "the World's Symbol of Peace and Justice". All Might wasn't just Number 1 in Japan, he was an international phenomenon. He was so amazing that he transcended the rankings entirely. He became a global beacon of heroism, not just Japan's top rank. To Endeavor, being bumped up a number is worse than meaningless, because despite the title, he's still just as far from All Might as ever -– but now with the pressure of trying to live up to a role that no simple number could approximate. A role that he understood better than anyone that he could never really fill. No wonder he got so upset about it.
** To put this into perspective, ''Anime/MyHeroAcademiaTwoHeroes'' expands on this: whereas the rest of the world have a 20% national crime rate on average, All Might's presence alone has suppressed Japan's crime rate down to ''the single digits''. There's also the implication that the US, the birthplace of heroes itself and where All Might trained after graduating from U.A., is not faring that well either, which is why All Might's retirement was a shock to the U.S. hero association as well.
* Todoroki's Quirk splits his fire and ice down separate halves of his body, with the left side being his fire half. ASinisterClue is a trope related to the fact that many people see left-handedness as a sign of being evil or demonic and tied to hell. The left side, the fire half, originates from Endeavor, whose Quirk is Hell Flame.
* A reason that Tsuyu tends to come off as Mineta's minder/friend more than viewing him as a pest sometimes: Tsuyu is the primary caretaker of her younger brother (and sister), and Mineta is fairly small. It's possible, to some subconscious degree, that she mentally compares him to one of her brother's friends and treats him more like a disobedient DirtyKid and seeks to parent him away from such behavior like she would a ten-year-old friend of her brother.
* One might wonder why no one ever went around warning people publicly about All for One, for even if the idea of him shadow ruling Japan was a shameful past, the possibility of him still being alive is a serious danger to people. However, Izuku commented that the 'shadow ruler of Japan' was an internet story. Trying to warn people about him would basically be telling someone the Illuminati was after him, and very few if anyone takes such a warning as anything but delusional paranoia.
* No one brought up the issues of Mina naming herself after Ridley, Alien, and the Xenomorph when it came to copyright, only that the name itself was weird. Failing to know legality wasn't probably in play though, as the series later suggested a lot of big franchises from the 20th century such as ''Star Wars'' and ''Harry Potter'' entered the [[Main/PublicDomain Public Domain]] by the present day, meaning that they do not fall under copyright concerns. [[note]] Disney still holds Mickey copyright because the "new" versions of Mickey (white gloves, anyone?) are still protected. It's not just a one-and-done; if they stopped making new Mickeys and using them in advertising and merchandise, they'd lose the copyright. [[/note]]
** As to why public domain wouldn't have been fought tooth and nail (see Mickey Mouse laws), there are several likely reasons. One is that the emergence of Quirks means that stories with superpowers aren't as lucrative, which has flaws. The other argument is that Quirk management legislation was pressing enough lobbying to make extending the protections seem stupid (likely combined with a backlash against superpowered fictions when Quirks were still controversial, making them less profitable to make movies and video games of to extend copyright). Nowadays, it could also be that movies about superheroes or fighting monsters are viewed the same way as racist movies are in our world –- discriminatory products of the time that no longer reflect views it's okay to hold, especially since mutant Quirks were some of the most discriminated against. Finally, it could be that it's just been long enough that even after extensions, the copyrights ''still'' expired, though less likely now that Disney is in charge of ''Star Wars'' and it's implied Disney's copyrights, like Universal Studios and Disney Land, are doing ''just fine.''
*** It's possible hero names aren't necessarily subject to as many copyright laws. Think Dove chocolate and Dove soap: very similar, but it's allowed because they're entirely different markets. Unless the movie studies are trying to send out branded superheroes of their own, it's entirely possible that a hero name referencing a movie or movie character just isn't worth the cease and desist, especially since it's extremely clear that it applies to Mina and not to anything within the movie, and shutting down a successful hero would just be bad publicity. If she was going around actively dressing up and acting like a movie character, it'd probably be worth it, but as it stands it's a totally separate industry. Laws also could have made exceptions for hero names, since the original licensed heroes likely would have been ''dying'' to reference old superheroes of yore when picking their names.
** Speaking of names, given Midnight's reactions to the names the students choose, it seems as if she is approving them based on her personal preferences. However, looking at how she gushed about "youth" multiple times during the Sports Festival, it makes much more sense. Namely, she's a fangirl, and as such her reactions to hero names are a good way to judge the reactions of the public as a whole.
*** Midnight is an expert on the court of public opinion. Public perception of her being a slut, for example, went so far as to ''change costume laws for superheroes against her,'' a move that she still protests and hasn't been able to undo. If there's anyone who knows the likely effect of a hero's name and appearance on their public perception, it's her.
* Izuku's hero name is written in a clearly shaky hand when presenting it to the class. It could be nerves... or it could be the fact that he's writing it with hands that are still recovering from surgery after breaking them fighting Todoroki. He can be seen gripping the marker with his entire hand when thinking of what to write. It's probable that he doesn't have fully functioning hands yet at this point.
* A minor one from the ''School Festival'' arc, but one part of the Uraraka versus Bakugo fight that ties into Aizawa calling out the pro hero who was calling out Bakugo, is that not only was the pro hero saying Bakugo was basically using Uraraka as a punching bag, he was also inadvertently calling Uraraka weak. By calling out Bakugo for not finishing her already, the pro hero was insulting Uraraka by implying that there was no way she could beat him. In addition, not only was Bakugo taking the fight seriously, but the pro hero was not aware of Uraraka's plan she had made for her final attack, making it clear he had no faith in her. As seen shortly after Aizawa called him out, Uraraka's last-ditch attack could of worked on Bakugo, as he himself notes he nearly failed to stop it. Not only would Aizawa be pissed about the pro hero calling out Bakugo, he'd be pissed that someone was calling one of his students weak as well.
** Theres also the fact that they should be able to see the debris floating in the air from the stands, Aizawa saying that they should retire wasn't just for the blatant sexism, but also because they were failures for not noticing Uraraka's plan.
* Why is Hawks helping Endeavor becoming a good Number One Hero after All Might's retirement? It's because he's a good [[{{Pun}} wingman]].
* Vol. 0 gives an explanation for why All Might, a Japanese-born superhero, would name all his attacks after places in the United States: Gran Torino told him to go across seas after Nana Shimura's death, to avoid All for One's influence. The America-themed attacks exist because the United States is where All Might officially began his career as a Hero.
* Another small one from the Sports Festival; During his match against Shiozaki, we briefly see Kaminari's hair float up around his head while he's charging up a big attack. It's not just a cool visual –- his hair is standing up due to static electricity.
* Jiro, who had low Quirk appreciation test scores, did a lot of physical training during her internship with Death Arms. A random choice perhaps, but think about how Izuku, Bakugo, and Ochaco's internships went, and how Fourth Kind wanted to teach Kirishima and Testsutetsu manners and how to hero outside of fighting and saving, one could take the interpretation that the internship she got was partially to work on a flaw of hers, namely her physical ability (she placed poorly on the Quirk test, which had a lot of physical fitness elements).
* The round that each winner took in the sports festival was due to their strengths, and the other two's weaknesses.
** The 4 kilometer race was won by Izuku Midoriya based on his forward planning and improvisation ability, which allowed him to surpass Shoto and Katsuki (who were only thinking on going forward and winning, and not much else.)
** The cavalry battle was won by Shoto Todoroki, who had the most thought out plan and teammate choice. Katsuki had ideas, but he had to be ''reminded'' of what his classmates could do, and Izuku wasn't able to really make the choices he wanted because of how high-risk his actions were (sound familiar?).
** Katsuki Bakugo won the battle tournament because he was solely focused on winning: Izuku was focusing on helping Shoto in their fight, while Shoto did not have his head in the game due to both Izuku's talk and his stress about his father (if he didn't taken the result of such combined power into account).
* Kirishima being able to bond with Bakugo makes sense beyond the former being just an all-around NiceGuy; Kirishima is also obsessed with things that are manly and is also not particularly smart at that. He likely sees the latter's No-Nonsense {{Jerkass}} behavior as manly. He also has [[{{pun}} thick skin]], so he doesn't get bothered by Bakugo's attitude easily.
** A video of the Chivalrous Hero, Crimson Riot, showed that he also had a rather gruff nature, even being prone to swearing. Kirishima's looked up to Crimson Riot ever since he was little, so of course he wouldn't mind having a friend with similar traits.
* It's noted on the YMMV Page that several characters, among them Tsuyu, invite UnintentionalUncannyValley reactions from some readers. These same feeling were likely in play during the emergence of Quirks when people were debating what was human. Those members of the audience are reacting just like in-story characters did back when All for One was young.
* One of the reasons Uraraka wants to be a hero is because she wants to earn enough money so her parents can have a comfortable life. As Iida said, there's nothing wrong with this, but why would she choose to be a hero when she could've picked some other high-paying job like being a lawyer or doctor? Well, turns out she has similar or the exact same reasons as Midoriya. [[ShipTease Guess they're more similar than they thought]].
** It's possible she was planning on going for that, had she not gotten into U.A. But since her Quirk was good enough to get her in, she just didn't need to take the harder options. Besides that, it seems like the medical industry is one of the few where you can get a license to use your Quirk if it's significantly helpful; Uraraka would have been competing against people who had better Quirks, more money, and better grades.
* One For All being revealed as passing on the Quirks of its previous users makes sense when you remember the power of the original Quirk that later became One For All. It was a Quirk with the power to pass itself on to another. It either already had the power to pass on Quirks other than itself (much like All For One) or by transforming into One For All, it gained the power to imprint the user's Quirk onto itself, strengthening One For All.
** One For All is explicitly described as a power-stockpiling Quirk. Quirks are super[[JustForPun powers]].
** It also has shades of SemanticSuperpower: One For All is the combination of a power-stockpiling Quirk, and a Quirk that lets the bearer pass ''their Quirk'' to another person. Nana Shimura's Quirk was ''Float'', for example, until OFA joined it in being her Quirk. And thus both of them are "her Quirk" to pass down.
* After the first user until All Might, every user of One For All had a Quirk of their own before being given One For All. They were born with Quirks, born special, and yet none of them could defeat All For One. It was only when Nana passed on the Quirk to somebody who wasn't born to be a hero, the Quirkless All Might, did the world's greatest hero, one who could defeat All For One, appear.
* Monoma's Phantom Thief code name makes sense when you consider his goal as an anti-hero: he's there to steal the spotlight from the more extravagant heroes. He also needs to be sneaky to make best use of his Quirk, as he has to touch someone to copy them and his powers work best when his opponent is unaware of what Quirks he currently has available.
* There's a good reason Iida didn't vote for himself as class representative, even as he wanted the job himself: as he said, the election was about people getting their classmates' trust, and voting for himself could have been considered "cheating" on his part.
** In the same vein, him eventually taking over as class representative with Momo being ignored in spite of being the deputy makes just as much sense: he earned the class' trust by showing he could do the job, while Momo didn't do anything in the same occasion.
* Why was [[CombatTentacles Black Whip]] the very first secret power Deku activated beyond One For All's habitual physical enhancement powers? Midoriya has been trying to cling and reach his dream to be a hero for years, even when he [[BornUnlucky couldn't]] [[SurprisinglyRealisticOutcome realistically]] [[DreamCrushingHandicap achieve it]]. So Meta-wise, it makes senses why Black Whip was the first Quirk unlocked –- Izuku is prone to try to reach and grab his goals impulsively. And the most fitting Quirk for that? [[PersonalityPowers The one that allows him to reach, grab and seize stuff far away from him with just a thought]].
** It's also somewhat similar to his mom's Quirk, which allows her to move small objects and pull them to herself. So the idea of 'pulling things to oneself' is somewhat familiar to him.
** Alternately, it could be that the Black Whip Hero was the second wielder, though only time will tell if Izuku unlocks the Quirks in chronological order.
*** The Black Whip Hero, Lariat, was actually the fifth wielder.
** The second Quirk he manages to activate is Float, which was Nana Shimura's (All Might's mentor). Now that he is achieving his goals by grabbing them, he wants to keep moving forward -- and what's best for that than finding a way to be able to fly? This is also a sign of the influence two other women have had in his life: his mother, who, when he was little, liked to make objects float to entertain him, and his first real friend, Uraraka, who can use Zero Gravity to make herself float as well.
** The third Quirk Midoriya unlocks is the Fourth's Danger Sense, an ability that causes a numbing pain when imminent life-threatening danger is coming. Fighting an opponent like Shigaraki, where just one touch can lead to death, makes having an ability like Danger Sense a must-have.
** Then he gets smokescreen as his fourth Quirk, because he just went vigilante and incognito since All for One is tracking him. What better Quirk to have to be hidden other than a built-in smoke grenade
** Now he has his fifth Quirk Fa Jin, and how does he use Fa Jin? To create a faux 100% due to the fact that he doesn't have time to exercise and build up to 100% normally, this works since Fa Jin works by repeated movements (which exercise is to its bare essentials), and at this point he rushing to defeat All for One (and is in a firefight)
* The main lesson Tsuyu learns in her ADayInTheLimelight episode in the Field Training Arc is the importance of following orders and being a team player. This explains why she emphasizes the spirit of Aizawa's allowing the students to use their Quirks against the villains in the School Trip arc (to protect themselves, not take the fight to the enemy), and why she takes the harshest stance against the unauthorized rescue mission.
* The third season's second opening begins with a scene of Class 1-A frozen in mid-air, with the exception of Bakugo and Todoroki, who are standing with their backs turned to the camera. At a first glance, it seems that the class is in pain or being attacked, and Aizawa looking away -- as if he was just erasing their Quirks -- gives that impression. But on closer look, the students aren't in distress, they're ''happy'', jumping for joy, because they ''passed the exam''. The last scene of the opening does something similar -- the students are all looking at the camera, while Bakugo and Todoroki -- the only ones who failed the exam -- are looking away.
* Toga's "[[{{Yandere}} love]]" for Stain takes on an interesting light after her backstory is revealed: both their Quirks involve drinking people's blood, something Toga's own family reviled her for, but something her Quirk compelled her to do. It's entirely possible, even extremely likely, that Stain had the same compulsions and issues she did growing up, and yet, in a twisted kind of way, he was accepted by a lot of people who embraced his ideology, like Spinner and Dabi. Did Toga, even subconsciously, hope to find some acceptance for "her normal" among Stain's followers?
* A CentralTheme in the series is "Legacy." Midoriya receives the legacy of All Might and One For All, trying to become the next great hero; Shigaraki received the Legacy of All For One, to become the next great villain. In later arcs, this even reflects in how they grow stronger: Midoriya is gifted with the Quirks of great heroes who came before him, willingly. Shigaraki, on the other hand, is building his power base by effective ''high-jacking'' the legacies of villains who came before him, like Stain's philosophy, Overhaul's bullets, and Destro's followers, and twisting them to his own ends. One For All passes strength on-All For One steals it.
* Weirdly, Midoriya is more similar to ''Endeavor'' then he is to All Might. Both of them have powerful Quirks that can seriously harm them if overused (One For All; Hellfire). Both have good analytical skills and good forethought. Endeavor is also one of the few who can understand Midoriya's TechnoBabble mumble-thons without any confusion whatsoever. Arguably, and somewhat ironically, Endeavor teaching Midoriya could help him improve far better than training with All Might.
* Ryukyu is portrayed as a very calm, collected, and patient woman, a stark contrast with her intern Nejire. In fact, it makes perfect sense for her to be Nejire's mentor. Strong as she is, Nejire can also be exhausting to deal with because of her near-childish personality and [[AttentionDeficitOohShiny short attention span]] (which may be even seen as [[AmbiguousDisorder a sign of ADHD]]); also, in a formal society like Japan, [[NoSenseOfPersonalSpace her touch-feely manners]] may be problematic for a lot of people. It takes someone not easily losing their patience to tutor her, and UA faculty may have specifically directed Nejire to Ryukyu because they knew the Pro Heroine was best suited for their promising but high-maintenance student. Ryukyu may also have picked her for this exact reason –- her curiosity and constant examinations of the people around her may easily pick things up that Ryukyu is too reserved to catch, at the same time that Ryukyu's cool demeanor balances Nejire out.
* When Magne sends Compress flying at Bakugo during his escape at Kamino, she does it by magnetizing both him and Spinner to have the latter repel the former. This trick only works if the "anchor"(Spinner) remains stationary for the "projectile"(Compress) to push off of -- something that would be difficult given the apparent amount of force involved. Which is why Spinner is the "Anchor" -- his Quirk lets him stick himself to the ground so he won't move.
* Early on after the U.S.J incident, both Shigaraki and Kurogiri were determined to be using aliases, a minor detail that quite notably exploded in importance as we later learn more about their origins. Very long foreshadowed on the author's part.
* Many of the heroes in the top 10 who have had Quirks revealed don't have Quirks that are traditionally easy to use or broken, such as Best Jeanist, Edgeshot, and Hawks. Someone like All Might or Endeavor is an exception to the rule it seems. There are a couple of ways to look at this, and one of them could be the idea that someone like Best Jeanist has to work a lot harder than someone who had a far easier Quirk and that hard work translated to results. There are, however, fridge horror ways of doing so. See below.
* It's discussed between the fandom that [[PowerCopying Toga' ability to use her transformations' Quirks]] is not compatible with the mechanics of the verse. However, it makes sense why this ability has never been explored before:
** For starters, a good deal of the population don't have flashy/practical Quirks to use in first place. It's likely Toga' victims didn't have Quirks to help them against her... or she killed them before they could use them.
** It also seems Toga lacks [[RequiredSecondaryPowers intuitive knowledge about her transformations' Quirks]], which averts the InstantExpert trope. She needs to see how they use their Quirks before to know how to activate and deactivate some of them.
*** Which makes her appearance in the Provisional License Exam more impactful: she saw how Uraraka used Zero Gravity during the test. While that wasn't her intention, Toga certainly found it useful during her fight with Curious.
** To make things more difficult, she needs to ingest her victims' blood to Transform into them; once she runs out of blood, she can't Transform into them nor use their Quirks. And acquiring blood for a specific Quirk is hard to her. She can't run the risk of wasting valuable blood due to trying to figure out her transformation' Quirk.
** Toga spent most of her life being forced by her parents to suppress her Quirk and only started going off the deep end after middle school, which in Japan spans from age twelve to fifteen. Toga is only seventeen years old, so she's had a lot less time to really experiment with her Quirk beyond simple transformations.
** In the movie, ''Two Heroes'', a concept called Quirk Numbers appear to be the [[SuperpowerfulGenetics chromosome version of superpowers]] (we can assume that it's where all the different data for Quirks are stored), which are also presumably in the blood!
* Endeavor's choice to more or less cut himself away from his family and move them has a second purpose: to keep them safe. With the war between the villains and the heroes rising, he likely wants to have them stationed somewhere as far as possible. Hell, it's likely he has come to the possibility of dying and thus has given them the seeds to have life without him.
* Dabi getting infuriated at Hawks' for killing Twice and his [[CondescendingCompassion offer of redemption to Twice]], in which Dabi overheard everything Hawks said to Twice, has more to do with his past and ultimate goals than actually caring for Twice as a person. After Dabi reveals his true identity to the public as Toya Todoroki, it makes sense why he was especially angry at Hawks. Hawk's talking down to Twice reminded him too much of his own life and the fact that he called Twice "unlucky" despite it being the very same Hero system that failed them in the first place made Dabi go understandably berserk. It doesn't help that he knows Hawks admires Endeavor, Dabi's father whom he hates and wants to demolish his heroic legacy.
* The first opening theme for Season 4 is called "Polaris," another name for the North Star. Because Polaris lies nearly in a direct line with the Earth's rotational axis above the North Pole, it stands almost motionless in the sky, and all the stars of the northern sky appear to rotate around it, making the North Star a fixed point for navigation to guide people home. The song is about Midoriya's and Mirio's declaration to protect Eri. They are the constant, unwavering stars that will guide her to a safe place and a real home.
* Uraraka's hero costume being a skin-tight body suit actually makes a lot of sense when one thinks about the nature of her Quirk and how it works. Any loose material, such as flaps and whatnot, would be affected by her zero-gravity abilities and potentially get in her way anytime she would need to make herself float.
* Both All Might and Nighteye chose someone like the other as their protege. All Might choose the intelligent, detail-oriented AwesomeByAnalysis Midoriya, and Nighteye choose the pure-hearted, ever-smiling, invincible brawler, Mirio.
* Why didn't All For One try to steal One For All? Probably because he can't. "All For One" allows the user to ''take'' someone's Quirk, and '''give''' it to someone else. "One For All" allows the user to '''give''' the Quirk to another person, but doesn't allow the user to ''take'' someone else's Quirk; as a tradeoff, "One For All" is a Quirk that can be '''given''' by the user, but cannot be ''taken'' from the user.
* Overhaul refers to his top agents as the "Eight Bullets of the Hassaikai." Bullets are inherently something to be used once and discarded, demonstrating quite clearly how he views them.
* For the most part the story manages to avoid the [[ParentalIssues Bad Parents]] trope that is common among super-hero stories. Bakugo's parents are well-meaning and acknowledge their failings with him and are willing to give him to UA in hopes of making him better. When Jiro explains to her parents that she wants to be a hero and not a musician she's in tears, thinking that she failed them in some way. Only to have them tell her to do what she wants, because they are always going to love her and be proud of her. Midoriya's mother is willing to pull him out of UA because she sees how it's hurting him and is willing to be hated for it so long as it keeps him safe. Even All for One is shown to be supportive of his protege Shigaraki, going so far as to support him and the League of Villains in Hosu.
** While Endeavor has shown he can be a [[{{Jerkass}} Bastard]], even he is taking steps to improve his relationship with his children; He's the exception, not the rule.
** The reason there's relatively few parental issues among the heroes, and heroes in training, is because being a hero is a recognized, highly respected career. In most series, the KidHero struggles to keep a SecretIdentity and continue his/her hero activities while keeping up with the civilian and family duties, which causes lots of parental friction; this doesn't happen in a series where the family can support the kid's heroic career just like they'd do with a military or police one. Also, being a recognized and remunerated career means that people with enough power and dedication consider becoming heroes from childhood, and in an orderly, reasonable manner, instead of being motivated by tragedy as it happens to many heroes in other series. As stated above, those who become heroes as a form of atonement, revenge, or motivated by negative feelings in general are the exception rather than the rule.
* When Bakugou agreed to help Kirishima study for the end of term exams, he was as explosive as usual. But this time, it's not Bakugou just being an asshole. His mom is a firm believer in tough love, she puts pressure on him to be strong by being harsh, and it was shown at the license course that he is willing himself to apply her methods to the young children. He was tough on Kirishima because he cares about the latter and wants to motivate him to study hard and have success.

* Given how several studies have proven that increased and regular sugar consumption makes brain activity deteriorate over time, Sato doping out and becoming sleepy after using his Quirk makes a whole lot of sense.
* America being the "Home of Heroes" might not just be an allusion to it being the largest influence of super hero comics. It's mentioned multiple times that the early days of Quirks were incredibly chaotic, and it was only through strict regulation that peace was achieved. Any one familiar with Japanese history might think this sounds familiar: it's similar to the Warring States period of Japan! It was only after Toyotomi Hideyoshi and Oda Nobunaga had basically made owning weapons illegal for all but a few elite members of society, and all of them members of the Shogun's administration, that peace was restored. Contrast this with America; where Japan fell into 150 years of civil war because of personally owned weapons, America used personally owned weapons to establish their country. And if you look at Quirks as natural, personal weapons, you can see how different cultures might see them. The US is the "Home of Heroes" for the same reason that it does really well in shooting sports; more permissive attitudes means that people have more opportunities to practice, and it's probably easier to get a license than in Japan.
* Aoyama choosing an English superhero name makes sense if you remember that he likes getting attention. English is the most spoken language worldwide, so a lot more people would understand the meaning of his name. Also, while it is true in real life that most French people stick to their culture and don't speak much English, Aoyama lives in Japan, so he is already used to another culture and while he himself is very attached to the French culture, he never showed signs he hates other cultures. His classmates were surprised that he chose an English name despite saying a lot of French words and that was very likely intentional in order to draw attention. He probably also wants to show that he doesn't look down on other cultures.
** Also, considering his name and the fact that he lives in Japan, it's also possible that his heritage isn't French, if at all, but he just prefers sticking to French culture (at least a big part of it).
* Aoyama's Quirk isn't compatible with his body, but this actually seems to be the principle behind his character design; his costume looks like a suit of typical HighFantasy armor suggesting a melee fighter, but functionally he's a SquishyWizard (seriously he gets one-shotted every time he's in a fight).
* All Might's bunny ears like hairstyle might be RuleOfFunny InUniverse. It has been established that he wants to make people happy and one of his ways of doing so is through comedy, so he probably chose that hairstyle for that purpose.
** This might also apply to other heroes who have something funny in their designs or names, take for instance the washing machine hero.
** Alternately, they're meant to invoke the victory sign.
* Deku's shoes go well with his bunny-like hero costume considering rabbits have big feet. Also, he has fluffy hair similar to fur.
* Bakugou's first try for a hero name was "King Explosion Murder". This might be a coincidence, but his hairstyle does slightly resemble a crown.
* Gran Torino is one of the few heroes who has gone up against All for One on several occasions without getting his Quirk yanked. His power isn't something that would mutate the user nor is it overly skill-based like Fiber Master. Why does Gran Torino still have his powers? Simple: he is a master of evasion and is hard for All for One to get a solid grab on him to remove Jet. The Warping Quirk is heavily implied to have not been present in the battle that cost All Might his guts and All for One his face, meaning the one power that let All for One catch him wasn't present. In an interesting coincidence, the other ally that we know All Might had in his battles against All for One, Sir Nighteye, could see into the future and was fast and quick enough to avoid blows by faster and stronger opponents, and he in turn trained a young man who could render himself intangible to physical blows.
* Rock Lock's distrust of the hype that U.A generates for its students, along with his debut in an arc sandwiched between stories debuting other hero schools, leads one with a pretty viable argument that Rock Lock did not attend U.A. It's possible his size-limited Quirk wouldn't even be effective on robots, expanding on the post Shinso battle of the Sports Festival.
* Deku's special move Delaware Smash has him flicking one finger at a time in order to create powerful shockwaves. Have you noticed that it's usually his [[FlippingTheBird middle finger]] he's using?
* All Might's secret identity is an inversion of ClarkKenting, or at least the opposite of what Clark Kent himself does. Clark Kent changes his name but his appearance would be recognizable in real life. All Might on the other hand uses his real name "Toshinori Yagi", which is known to the public, but real-life people wouldn't recognize him by his appearance alone if they didn't know prior it's him.
* The second opening theme for Season 4, showing Class 1-A happily preparing for the festival, seems like a big case of MoodWhiplash since we first see it right after the episode where Sir Nighteye dies a tragic death. But what were Nighteye's last words to his comrades? To cheer up and smile, because a society without joy and laughter has no bright future.
* Why do many people start believing Dabi's recording about Endeavor and his criticism of heroes in general, despite his false claim of Best Jeanist being alive? Simple. Best Jeanist was missing from the public masses for months and didn't return to help until Gigantomachia was at Shigaraki's location. Even if what Dabi said wasn't true the public feels that the real liar was Best Jeanist as he didn't announce to the public about his recovery and his disappearance meant he lied to the public, not just Dabi. The fact that best Jeanist lied about his disappearance, and having the highest approval rating of the masses, only reinforced Dabi's claim that heroes are just criminals who lie while holding masks of justice.
** There's also the fact that people will wonder why he was so convinced. Even if most don't believe it, there will be some who will conclude that Dabi was presented with a corpse that was passed off as him. Which will lead to those people wondering how that was done with some thinking it was fake and others thinking someone was killed for the charade. All it takes is one person posting such a theory on the internet on the right site and the rumor will become wide-spread even if most dismiss it.
* Speaking of Dabi and the public, wonder why Endeavor decided to come forward with the truth and acknowledge Dabi's accusations against him instead of lying to comfort the public in the aftermath of the Paranormal Liberation War? Simple, aside from Endeavor's current goal of atoning, he couldn't lie to the public despite knowing the truth because it would mean he would have to face Dabi himself in battle to prove he isn't his son,something he dreads so Endeavor comes clean to avoid facing his own son in battle.
* One For All being dangerous for those who already have a Quirk makes more sense when one remembers that it was originally a Quirk designed to empower the weak and oppressed (the First Wielder) to fight against the strong and tyrannical (All For One). Those who already have power (those born with a Quirk) cannot safely keep One For All without its power burning through their life force. Only those with a strong sense of justice but too weak to fight against evil, like the First Wielder used to be, can safely use One For All to its full potential.
* One For All being deadly for Quirk Users gives it another layer for it to contrast with its sibling Quirk All For One. All For One hoards all the powerful Quirks it can and while One For All can also hoard Quirks, it is deadly for Quirk Users to hold onto and can only be safely used by the Quirkless. The Quirkless cannot pass on any Quirk Factor and so, One For All can't possibly hold as many Quirks as All For One can.
* On the subject of those two Quirks in particular, it's interesting to note that All For One is an evil counterpart to One For All. Both are able to [[AllYourPowersCombined stockpile other Quirks inside themselves]], but in opposing ways. All For One [[PowerParasite steals the Quirks of others]], ripping them away without consent. One For All [[PassingTheTorch is a Quirk that can be passed on to others]], a gift willingly given. All For One stockpiles many Quirks during a single user's lifetime, while One For All can only acquire a single new Quirk per user.[[labelnote:*]]Unless the user has multiple Quirks to begin with.[[/labelnote]] All For One makes stolen Quirks stronger by stocking multiple copies, while One For All contains a single copy of each Quirk and grows stronger each time it's passed on. All For One leaves its victims Quirkless, while One For All was created to give a (seemingly) Quirkless individual a Quirk. All For One ignores the feelings of its victims, while One For All bears its prior hosts within it, forever preserving their feelings. All For One [[HowDoIShotWeb doesn't come with a Quirk instruction book and won't make you as good at using a stolen Quirk as the Quirk's original owner]], while One For All lets every gifted Quirk's original owner come with it and teach you how to use their Quirk themselves. All For One lends itself to highly strategic usage with a massive toolkit, while One For All defaults to [[WhenAllYouHaveIsAHammer but a single hammer]] unless you awaken the bequeathed Quirks sleeping inside. All For One lets its user steal Quirks to extend his life, while One For All causes RapidAging by burning through its user's life force if they already have a Quirk. Both Quirks have the same end result of giving the user multiple peoples' Quirks in a single package, but [[NotSoSimilar take exactly opposite paths to get there]]. ...And, y'know, All For One's owner ''created'' One For All, albeit not entirely intentionally.
* Midoriya's battle against Overhaul makes a ''lot'' more sense after the Paranormal Liberation Arc. Notice how Midoriya was zipping through the air with One For All: Full Cowl 100%? Think about what "100%" means for a moment. Full. Complete. Perfect. Everything. ''All.'' True 100% includes ''all'' of the bequeathed Quirks, not just the base power stockpile, and what did we see in that battle? Deku '''float'''ing in the air with the shockwaves of his movement, and (in the anime) '''whip'''ping Overhaul apart with his lightning aura before the final punch. One For All: Full Cowling '''''100%'''''. That may have been the moment when Izuku began to unlock its full potential, and he might very well have been subconsciously using the basic power-stockpiling as a precursor to Float and Blackwhip.
%%* In chapter 300 hero society is crumbling relatively fast as more and more people are taking arms to defend themselves from villains and criticizing the heroes, even the ones who stay to help despite the criticism, but people losing their faith in heroes didn't happen overnight.
* It might seem like an AssPull to some for Deku to manifest the quirks of his predecessors when All Might, the most successful user, never could; but it does make sense from a meta-perspective. All Might is a clear {{Expy}} of Golden Age Superman whose "powers" were mostly just applications of his super-strength, hence as his successor Deku is an expy of Silver Age Superman. And what is the most standout feature of silver age superman stories? ...NewPowersAsThePlotDemands!
* Why was All Might immediately able to One For All at maximum strength, while Deku still can't do the same without breaking his bones? Well, it's stated that All Might held onto the Quirk longer than any of his predecessors. It stands to reason that, powerful as it may have been, the Quirk's power maxed out at a level that All Might's body was simply capable of enduring when he got it. The same isn't true for Deku because the work All Might put in over his forty or so years in service had the knock-on effect of giving the Quirk a '''significant''' boost in power, which leads to broken bones in a young vessel whose strength didn't grow in tandem with the Quirk like All Might's did.
* Deku manifesting his own version of All Might’s GlowingEyesOfDoom in his new hero look might not just be artistic merit, or a sign that he’s adopting a similar self-destructive mindset of his mentor used to possess whilst upholding the image of the symbol of Peace in his new role as a Vigilante protector in this time of Crisis. One thing that always differed from All Might’s usage of OFA compared to Izuku’s was his ability to somehow shift forms between his true gaunt, thin appearance and his muscular, heroic form for performing on the job. All Might’s comparison to somebody with a flabby stomach "sucking in his gut" to appear better than he actually is might work as a comparison, but still doesn’t really explain ''how'' All Might -- the first Quirkless user of OFA, is actually able to pull the effect off, up to and including a visible transformation effect of generating steam from his body as he "deflates", which Izuku notably commented upon during the climactic confrontation at the end of the USJ arc as a sign All Might was bluffing about his ability to continue fighting... until recent chapters revealed that one of the Quirks contained within OFA is '''Smoke'''screen, allowing the user to generate obscuring cover to hide themselves from sight. Since All might’s focus was similarly on preventing anybody witnessing him transform into his ‘pathetic’ true self early on in the story, and the other vestiges later commented on how well Yagi had adapted to OFA, thanks to his Quirkless body being a natural fit for it, almost to the point of it reaching the singularity stage by the time he passed it onto Izuku, it’s possible that Yagi actually ''was'' manifesting partial effects from the other Quirks stored within OFA unknowingly, and assumed instead they were merely by-products of his injured body struggling to continue fully utilizing OFA's full power. His blackened sclera might be tied to another of the effects of the remaining Quirks stored within OFA, which Deku himself is now manifesting when he’s in combat mode, due to him fully unlocking all the associated powers held within OFA.
** All Might potentially (and unknowingly) making use of smokescreen is granted more credibility when one considers that [[CombatTentacles Black Whip]] originally manifested as a result of Midoriya's desire to capture Monoma. It's reasonable to assume that All Might's desire to hide his true form may have served as a similar kind of trigger for the Smokescreen Quirk.
* For a while, it seemed like an incredibly ContrivedCoincidence Kota ended up running into the very same villain that killed his parents during the lodge attack, just so Izuku would have an opportunity to convince him of the value of heroism in rescuing him from Muscular, but it’s heavily implied that there’s more to Muscualr’s presence in the attack than just random coincidence. [[https://official-ongoing-2.gamindustri.us/manga/Boku-No-Hero-Academia/0075-003.png Looking at the map of everybody’s positions]] and the order in which they revealed themselves/attacked the protecting pro heroes, it becomes clear that each member of the Vanguard Action Squad is positioned to best execute their abilities in a complimentary manner, and displays uncanny knowledge about which heroes ''specifically'' will be protecting the students. Firstly, the Squad takes out Ragdoll at some unknown junction and abducts her before the attack even fully begins, taking advantage of the fact she’s the furthest away from the group, and also preventing her Search from being used to locate all the students when the attack commences. AFO’s comments in Kamino Ward afterward indicated that abducting her so he could steal her Quirk was a priority for the villains, second only to Abducting Bakugou himself, which comes into play with Tomura later being able to use Search to accurately keep track of Izuku and OFA, showing that AFO was fully aware that the Pussycats were the designated heroes assigned to watch over the students and worked that into his plans. Mustard then begins unleashing his gas throughout the forest to subtly poison all the students before they realize they’re under attack, ensuring that there ''will'' be students who are harmed from the incident even if the Vanguard Action Squad ultimately fail to kill or main any of them, which fits both Dabi and AFO’s overall goals of worsening the public image of UA and the ability of official heroes to protect others. Dabi then lights a fire to distract and confuse everybody, drawing out the teachers in the lodge so he can launch a sneak attack on them via Twice’s cloned version, and working together with Twice to continue sending a steady barrage of Dabis against the best-fortified building around as disposable Suicide bombers, going along with Dabi’s self-destructive Quirk, preventing reinforcements from reaching the clearing or the Pussycats being able to safely escort the students back to the lodge.
** Magne then uses her magnetism ability to draw Pixiebob close for an unavoidable sneak attack before they’re even fully aware of what’s going on, preventing her [[DishingOutDirt Quirk]] from being used to protect the kids from the blaze or keep the villains at bay with temporary fortifications. [[note]] Additionally, their Quirks have good synergy, with Spinner’s Quirk enabling him to remain in place, sticking himself to one location to be used as an anchor or repelling point for Magne’s Magnetism.[[/note]]As well as that, there are two villains assigned to each loop of the forest path, one sneaky villain[[note]]Toga, Compress.[[/note]] Partnered with one brute-force villain [[note]] Moonfish, Chainsaw Nomu.[[/note]]to best complement each other’s preferred fighting style whilst they search for their target. [[note]] As a bonus, the Chainsaw Nomu can fight best in the poison gas-filled areas of the forest, unaffected by the fumes either through its modifications or the apparatus in its mouth.[[/note]] The only odd one out is Muscular, who admits that he "came up here for the view" -- and based on the fire in the background, the cliff must face south-east -- meaning the only thing that can be reasonably seen from there is the clearing where the other Pussycats are. Given how coordinated the other villains are, and how Muscular notably has a much-lower intellect than the rest of them according to the databook, it’s highly likely his intention -- and assigned goal during the operation -- was to join up with Magne and Spinner in the clearing, but he got lost in the forest, then distracted by a ‘fun toy’ along the way. If Muscular had joined the clearing fight, his brute strength would have been the decisive factor in taking out the next most important target on the priority list -- Mandalay. Without her, the heroes lose all communication throughout the forest and cannot regroup the students.[[note]] Plus, if Pixiebob hadn’t been knocked out, his strength would have allowed him to easily tear through any earth constructs she could make.[[/note]] Though it’s never stated, it’s implied that Mandalay needs to concentrate and keep a clear mind in order to effectively use her Quirk -- and with her sister’s killer staring her straight in the face and laughing about how much fun he had killing her, Mandalay wouldn’t have been able to concentrate enough to get any messages out to the kids in time. This means that it wasn’t a coincidence that Muscular ran into the surviving family members of one of his victims- rather, he was likely recruited '''specifically''' for this job because he’d killed Mandalay’s sister, with his usefulness as a powerful attacker being a secondary concern. [[SpannerInTheWorks It also means that Izuku unwittingly interrupted one of the lynchpin moves in the League of Villains' plan when he ran off to rescue Kota, and took out one of their strongest foes before he could even make a move to seal their victory, explaining why the fight starts to turn against the Vanguard Action Squad after Muscular goes down.]]
*** Which becomes FridgeHorror when you consider that if Izuku died, not would that mean Kota would be murdered as well, but then Muscular would likely head down the mountain to meet up with the others and likely kill at least one of the other pro heroes. And if Mandalay would have trouble concentrating on her quirk while fighting her sister's killer, finding out he killed her nephew and one of the students she was trying to protect on top of that would make it near impossible. And considering that Muscular could likely take every hero in the training camp with the possible exception of [[PowerNullifier Aizawa]], who was both crippled and had lost to UnskilledButStrong before, there would be a non-zero chance of '''no one''' getting out of that camp alive.
* Although Magne, a transgender woman, being a LadyLooksLikeADude may carry UnfortunateImplications, it also makes sense that she's not able to pass very well. Many members of the League of Villains are from [[EqualOpportunityEvil marginalized groups]], turning to villainy because of social and financial difficulties. Magne likely grew up poor, making her unable to afford voice training, hormones, surgery, or other steps in her gender transition. Compare her to Tiger, another transgender character who grew up in a supportive environment and was able to undergo a full medical transition including gender confirmation surgery. Magne and Tiger serve to represent the class divide in hero society, where societal inequality pushes the poor to villainy in order to survive and be respected.
* Midoriya being in Class 1-A is actually very fitting, given his Quirk: 1 for '''A'''ll.
* With the Chapter 336 reveal that Yuga Aoyama had received his Quirk from All For One and was forced to be his [[TheMole mole]] in UA, his actions when befriending Izuku make a ''lot'' more sense. Creepily watching Izuku through the window and leaving the message "I know" was weird at the time, but he was able to deflect it as just part of his eccentric personality. But now it becomes more apparent that he didn't just recognize that Izuku also had a Quirk that his body couldn't handle, like he said, but that at the time he suspected that Izuku might ''also'' be a plant sent by All For One.
* Yuga Aoyama's number according to the 1-A seating order is 01. [[TragicVillain He had nowhere to go other than down]].
* Despite its powerful versatility, Momo Yaoyorozu's Creation likely wouldn't be a handy Quirk for All for One due to the user requiring a good reserve of body fat and in-depth knowledge of elements to a molecular level. This especially also wouldn't be a good use for a [[DumbMuscle Nomu]] aside from Kurogiri.
* When asked about [[ShipTease if she has a relationship with Kamui Woods]], Mt. Lady just responds with "no comment". Due to a large part of her InUniverse fanbase being fueled by her sex appeal which she gladly uses, any official reports of a relationship would instantly cause a large amount of her fanbase to collapse.
* All For One being Izuku's ultimate ArchEnemy rather than Tomura, despite their EvilCounterpart natures and thematic parallels storylines throughout the manga, was foreshadowed in their proper one-to-one talk at the mall. Izuku highlighted to Tomura that the main difference between [[StupidEvil him]] and [[WellIntentionedExtremist Stain]] was that he could understand with and empathize with Stain's perspective of the world, even if he couldn't accept his actions and opposed him for it, something Stain found commendable in him. However, the same conversation also started to make both Izuku and the reader understand ''Tomura's perspective'' at that same point, hinting at his DarkAndTroubledPast and having him vaguely allude to the BystanderSyndrome that so negatively affected him back in his childhood, and was arguably the greatest factor in him choosing to extend his hatred to all of society. In contrast, when All For One's motivation is revealed in the following arc, it turns out that he became a ClassicVillain [[ForTheEvulz because he wanted to]]. He had the power to affect the world and he went out of his way to choose to be a horrible monster for no reason than [[EvilHasABadSenseOfHumour he found it fun and exhilarating to do so]]. In contrast to Tomura's true status as a TragicVillain, All For One is a far more incomprehensible villain who has no real greater motive or overarching reason for his vileness, and is later shown to be a less effective villain for it, as he cannot successfully steal [[ManySpiritsInsideOfOne One For All]] because he's such a FlatCharacter. Is it any wonder that Izuku would wind up so opposed to somebody that greatly embodies the very same [[CompleteMonster character flaws]] he criticized in Tomura, and would actually desire to ''save'' the latter once he understood his origins?
-->'''Izuku:''' Well, I can't accept what you do, and I don't understand it...The hero killer... Although I can't accept him, I ''do'' understand him.
* The beginning of the final stand against All For One in Chapter 343 starts when Aoyama suddenly shoots his Navel Laser at him in retaliation, which is deflected by the villain into the sky. Soon after All For One summons the League of Villains through his Warp Quirk, the heroes suddenly appear through a repurposed Warp Gate. This may as well be a reference to Aoyama's attempted HeroicSacrifice during the Provisional License Exam where he fires his Navel Laser to the sky to draw attention away from Iida, except he unintentionally also beaconed Class 1-A to his location. HistoryRepeats!
* Chapter 346 shows there is an upside to Monoma being only able to copy the bare bones of a Quirk. While he can't replicate stored resources, if the original user of a Quirk he's mimicking has sustained injuries that diminish their power, Copy won't replicate the damage so the Quirk will function normally for Monoma. Thus, he's able to fill in for Aizawa during the fight against AFO after the hero loses one of his eyes.
* The reason Toshinori Yagi glows more brightly than the other vestiges is likely because he's contributed more to One for All's power stockpile than any of them by far. Yes, the others had actual quirks to give (as well as the fourth user's physical training), but in order to be the Symbol of Peace, All Might had to constantly push himself harder than any user before him every single day, from day one--for over thirty years. And Quirks are like muscles, when you challenge them, they get stronger, particularly OFA.
* Star and Stripes wasn’t just TheDreaded to AFO because of her StoryBreakerPower. By this point, AFO now has likely recognized that Midoriya is displaying the quirks of the previous OFA wielders. If she met with Midoriya, he could possibly give Star OFA to make herself [[BeyondTheImpossible even more busted,]] and she’d have All Might there to help advise her on how to use it against him. Alternatively, she could take OFA for only a few moments, then give it right back to Midoriya, meaning that Izuku would have New Order added to his quirk arsenal, and AFO would get curb stomped by both Midoriya and Star.
* So far, those who received many Quirks like Gigantomachia, Spinner, and Noumus have all shown to have decreased intelligence and a multitude of mental issues. This is likely because Quirks essentially have a “soul” of the user imprinted on them and by inserting those Quirks into different people, those “souls” start to merge and it becomes far harder for the individual to remain themselves from the conflicting emotions such a process entails. Those with stronger wills, like Lady Nagant, can forcefully assert their individuality and not have much side effects with an extra Quirk or two. But for those with weaker wills, like Spinner, their minds will be ruined by the extra “souls” within the Quirks they were given.
* More like Fridge Humor, but bear with me: It makes sense that some of the villains- namely Shigaraki and Spinner- to be ''VideoGame/LeagueOfLegends'' players, as in RealLife League Of Legends is '''infamous''' for its ''very'' toxic fanbase.
* Once they're fully revealed, the 6 additional Quirks within One For All are revealed to have a complimentary Yin-Yang relationship between certain pairings, with their particular Quirk's abilities [[RequiredSecondaryPowers countering or nullifying the disadvantages]] of the other. In fact, Izuku unlocks/reveals each Quirk in an order that showcases which pairing they're meant to combine together with: Black Whip - Float - Danger Sense - Smokescreen - Fa Jin - Gearshift. Furthermore, they each fall into 3 categories: Combat, Support, and Movement.
** [[SuperSpeed Gearshift]] and [[ChargedAttack Fa Jin]] are the Combat. Mirroring their user's close bond in life, the Quirks work together in unison well. Gearshift's speed increase initially allowed the Second to manipulate the environment to his advantage in a fight through altering the projectiles he launched, but its initial weak state meant that it was limited in directly attacking somebody with his bare hands, forcing him to [[WeakButSkilled rely on intermediaries like guns]] to remain a credible threat with his power. Fa Jin is powerful in a fight, especially since it allows Izuku to side-step the disadvantages of unleashing more power than his body can handle at a crisis period where he ''needs'' 100% strength attacks, but its charging period can be tricky to pull off mid-battle effectively, especially against any LightningBruiser or tricky opponents who can keep up with Izuku's own speed. Combining the two together cancels out their mutual disadvantages, effectively granting Izuku a SuperMode of One For All that can 'warp the very fabric of reality'.
** [[SpiderSense Danger Sense]] and [[SmokeOut Smokescreen]] are the Support. Smokescreen allows Izuku to obscure his movements on command and get the drop on his enemies, but since Izuku can't directly see through the smoke either, it also runs the risk of this working to the Villain's advantage as well, allowing Izuku to be blindsided. Danger Sense, however, enables him to keep track of any incoming threats, preventing this being an issue, albeit the Quirk's specific trigger being only 'malicious intent' still leaves it with some [[{{Yandere}} blindspots]] it cannot predict. One robs Izuku and his enemies of a vital sense, the other gifts him an extra sense that allows him to compensate. Neither offer direct advantages to Izuku physically, but are [[SupportPartyMember useful support options]] that allow him to anticipate ambushes or launch his own on command, enabling him to keep control of his immediate environment no matter what.
** [[NotQuiteFlight Float]] and [[ProjectileWebbing Black Whip]] are the Movement. Float allows Izuku unparalleled movement in mid-air, especially once combined with One For All's base strength to enable him to change direction in mid-air on a dime. However, the same recoil movement means that Izuku cannot unleash his stronger attacks whilst suspended in the air lest he blow himself away from his target. Black Whip however, enables Izuku more limited movements that relies upon [[BuildingSwing latching onto his surroundings and using his enhanced strength to swing around]], but this same ability to grab onto targets and hold tightly to them means Izuku can freely change course without losing his momentum or launch attacks at targets outwith the reach of his hands. Their combination is effectively demonstrated against Tomura during his and Izuku's solo mid-air clash in the Paranormal Liberation War, with Blackwhip furthermore enabling Izuku to carry multiple people aloft at once, whereas Nana was limited to whomever she could hold with her own two hands.
** Furthermore, this Yin-Yang theme is present even in the 7th 'base' power of One For All -- more specifically, it's first and last wielders. Izuku at the manga's start is almost exactly like Yoichi was, a powerless individual who deeply admired the ideal of heroes and wanted to help others selflessly, despite his physical limitations, and was winningly to stand up and do the right thing even if it was reckless and hopeless of him to do so against literal superhumans to him. Whereas Izuku was genuinely born powerless and in chapter 1 is a literal child with all the strength and abilities of one, Yoichi had a quirk that was so weak and specific in usage that he ''seemed'' powerless, and despite being a grown adult, his health issues and frailty meant he was hardly better off than Izuku. The difference between them is that Yoichi's physical disabilities and weakness meant he could never grow stronger physically enough to confront All For One, but his ''spirit'' remained as strong and steadfast as ever in opposition to his brother, and this same spirit would be passed on after his mortal death to reside within his quirk. Izuku meanwhile, has the capacity to physically grow stronger and capable of unleashing One For All's ''true'' power beyond what any other the other successors could safely unleash, ''because'' of his unique 'weakness'. In contrast to Youchi's steadfast confidence and optimism, Izuku's weak spirit is something that handicaps him and allows All For One to psychologically manipulate him with ease in the lead-up to the final battle, and he only starts overcoming that with the aid of multiple allies, in contrast to Yoichi being isolated from many people by his brother's controlling nature. Yoichi is hinted to have died without successfully saving a single person, whereas Izuku is destined to become the greatest hero in the world thanks to the power he received from him. Yoichi was the weakest holder, and his power was to give what meagre strength he had away. Izuku is the strongest holder, and the one most suited to ''receive'' Yoichi's gift in the end, to achieve the dream he could not.
* Take a look in the background of the scene showing the aftermath of Gentle's fight to contain his fellow prisoners. There is a steal beam that's been wound tightly around a group of prisoners. How could Gentle have done this? Simple: he must have figured out that making things rubbery doesn't just make them springy, but ''flexible'', which would presumably let him bend steel with his bare hands no matter how hard it actually is.
* Toga gains the ability to copy the Quirks of those she imitates, but only if she's very emotionally close to them. During the final battle, she attempts to copy Dabi, All For One, and Tomura, but fails to replicate their Quirks. Dabi is an AloofAlly and an IneffectualLoner, and while he did try to console her, it was too little too late for her to care enough about it. All For One is a complete {{Sociopath}} who goes intentionally out of his way to be hated by everyone, and almost all his "allies" - Toga herself included - only work with him out of personal convenience. But what about Tomura? Toga seemed to have a decent relationship with him... but not with the [[MindHive fusion of Tomura and AFO]]. And the "Double" Quirk requires the user to have a perfectly-accurate mental image of what they want to copy: Toga has the measurements of [=TomurAFO=], but not the "original" Tomura - meaning that she can copy the former, but not the latter.
* Tamaki being annoyed at Class 1-A assuming that Mirio is where he is because 'he has a strong quirk' was pretty clear about how it was ignorant of how much work it took to make Permeation so effective. However when you also add in how Nejire got social issues from people assuming her super-strong quirk made her look down on them, which had a ''drastic'' effect on her, it's clear that statement offended Tamaki on behalf of both of his friends, not just one.

* Of all of Bakugo's peers, despite being the weakest in terms of power Sero is the one least afraid to mock him and take advantage of his character flaws rather than ChildhoodFriend Deku, ClassClown Kaminari or RatedMforManly Kirishima. This might seem weird but it fits his role as a Spider-Man expy.

* [[RatedMForManly Tiger]] stands out quite a bit from the other Wild Wild Pussycats, who are quite girly. He's revealed to be transgender, implying he joined/founded the team before transitioning.

* All of the League of Villains seem to react the way you'd expect them to according to basic human psychology, except for Dabi. Spinner, Twice, and to a lesser extent Mr. Compress are all outcasts, and just want someone to accept them. Shigaraki was brainwashed. Toga is delusional. But Dabi seems sane, and yet his rage at Endeavor comes off as InsaneTrollLogic considering that the man was downright benevolent to him compared to the rest of his family. Then you start to think about just how extreme Endeavor got at his worst. Toya's selfish personality, need for validation, and desire to take risks as a child show that he got a ton of Endeavor's negative traits. And as an adult, Dabi is the only one of the League who doesn't have at least one other member he cares about (even Shigaraki stated that he was willing to relent on his "destroy everything" goal to spare what his companions cared about). Of course Dabi's logic makes no sense to normal people, ''he's a literal psychopath''.

** This isn't necessarily incorrect, but its an oversimplification. [[spoiler: Toya Todoroki was born with parts of both parents' quirks: his father's flame and his mother's ability to tolerate cold temperatures.]] This shows its not as simple as getting a quirk or not getting one. Shoto avoided this problem by essentially having one quirk on each side of his body.
