Abandon Shipping: Not as drastic as expected, but some Inko Midoriya/All Might shippers jumped ship when the former's character bio revealed that she was still married, and the reason why her husband, Hisashi, hasn't appeared yet is that he works abroad. The same applied for those who pictured All For One as Izuku's father. Of course, Hisashi still gets Die for Our Ship to make Inko/All Might happen in fics.
Acceptable Professional Targets: The news media is not shown in a very good light in this series. Not only do their reports often unwittingly help the villains, but they're also shown to have it in for U.A. It's also suggested that the news media is partly to blame for many heroes being more concerned with fame than actual heroism. The fact that one of the leaders of the Meta Liberation Army is the head of a publishing company and former reporter doesn't help. The only media character portrayed in a positive light, Taneo Tokuda, appears exclusively in the anime, and the best thing he does during that episode is not doing his job by withholding the scoop he discovers and lying to his boss about it.
Bakugo and Endeavor's Character Development can be seen as a story not about rejecting anger, but learning to focus it. Both characters develop into more heroic figures, but they are only slightly less angry than before, they just learned to focus it on their hero work, instead of misdirecting their anger and frustration towards other people who have nothing to do with it (in Bakugo's case, Midoriya, and in Endeavor's case, his family).
A recurring takeaway from multiple villains' backstories is "marginalization leads to criminality". Spinner was victim of prejudice for being a mutant, it's implied the same thing happened with Magne for being transgender, Twice was dealt a bad hand and had to live on the fringe of society alone and in poverty for years, and something similar happened to Gentle and La Brava.
Aoyama's Quirk. While it's been stated that the blast comes from his belly button, when seen at the wrong angle, it looks like it's coming from his crotch. It gets even more equivocal in Chapter 256. Aoyama can now concentrate it in a "saber" poking out. Then Hagakure, using a new ability of hers, manipulates it.
Mineta's not only a source of loads of intentional innuendo, he's a source for some that seem to be accidental as well:
His Quirk lets him make sticky balls.
"Mineta" is Polish for "cunnilingus". This is the reason why most Polish fans prefer referring to him by his first name. It's also very similar to the word "minet", which is Russian for "blowjob".
When everyone is coming up with their super move, we see Mineta connecting several of his balls together to use as a rope or whip, but it also looks suspiciously like anal beads◊. This is probably intentional though, due to how perverted Mineta is.
Kirishima's Quirk is referred to as "Hardening", which is what it sounds like in the most literal sense. While Tetsutetsu's similar Quirk, "Steel", is slightly better, they're still guys who have getting hard, as in being extremely durable, as a superpower. Additionally, Tetsutetsu suffers from metal fatigue.
Bakugo's reaction to finding out about Endeavor's actions. Was he just horrified at what he learned on the surface about Todoroki's home life? Or was he horrified at the possibility of becoming like Endeavor with his own desire for being number 1? Or is it a combination of both?
Whether All For One's relationship with Shigaraki is genuine or just manipulative (or even both) is still debated. The Reveal in Chapter 92 that Shigaraki is in fact the grandson of All Might's mentor doesn't help matters. Later chapters during Paranormal Liberation War Arc heavily implied it to only be manipulative, with All For One possessing Tomuras body against his will and implying he literally wants Tomura to be the next me by fully controlling his body. However, even after gaining full, definitive control over Tomuras body, All For One still continues to insist he is not just a mere pawn and is someone very important to him and assures Spinner he has the utmost need respect for Tomuras will, which could just be All For One being manipulative again or being genuine in his statements.
Did All For One really find Tenko/Tomura by chance, or did he instigate the events that led to it? Considering that All For One has the power to bestow Quirks on people, it's possible that he somehow found out about Tenko being Nana Shimura's grandson, then gave the previously Quirkless Tenko the Decay Quirk, thereby causing the tragedy that killed the Shimura family. Additionally, does All For One truly see his subordinates as mere pawns, or does he genuinely care about them to some extent at least. In the past, he granted the wishes of desperate people in return for favors and kept his promise so to them but then according to his younger brother "disposed of them". Did All For One not care about them, or did he see it as an equivalent exchange and "disposing" of them as not being a bad thing. Did those people even suffer? Did he even truly "dispose" of them? Not helped by the fact that during his fight with All Might, he bitterly recalls how the latters fist took down one after one of his followers and states the up-high view must have been nice standing atop their sacrifices.
Bakugo refusing to let Midoriya rescue him during the Forest Training Camp Arc. Was that Bakugo prioritizing his ego even in such a dire situation and refusing his rival's help or was it him realizing that Midoriya would probably die in the process and trying to stop him from doing it? Or both?
Was Best Jeanist's mentoring of Bakugo an attempt to correct the flaws in a talented but troubled young hero, or was he simply pushing his values on Bakugo? Or perhaps some combination of the two?
When you consider that Aizawa re-enrolled the students he expelled, what does that say about his claim that he'd have expelled both the students who went to save Bakugo and the students who didn't do anything about the first group if not for All Might's retirement? Did he honestly mean it, or was this another rational deception to get the students to behave themselves and apply themselves to their studies in order to become model heroes?
Was a young Gentle's ill-fated attempt to help the falling worker more motivated by a desire to be a hero or to get attention? More specifically, there's his decision in the manga to use his Quirk to create a trampoline to reach the man, rather than to cushion his fall. Was that a mistake made in the heat of the moment, not to mention possibly due to inexperience with his Quirk, or was it because Gentle wanted to be seen saving the man? It's worth noting that in the anime, he tries to cushion the man's fall, but the outcome remains the same, suggesting that it may have been intended to be seen as a case of making a mistake during the heat of the moment, but even that still leaves it open for interpretation.
On a ship related note, there's Tsuyu/Aizawa, a popular couple in Japan that has almost no fans in the West and is mostly considered Squick. This is related to Values Dissonance, partially due to teacher/student relationships and an age gap within a couple being much less taboo subjects, and also due to perceived ship tease between the two. The same also applies to the Aizawa/Midoriya and All Might/Midoriya ships, that are far more well received in Japan than in the West.
Endeavor is a far more controversial character in the West than he is in Japan. In the West, he is generally seen as a despicable patriarch and Domestic Abuser with no redeeming qualities whatsoever. In Japan, however, people are more neutral about his behavior. This only got worse after Endeavor has a Heel Realization and actually tries to be a better hero and father. The West feels like he doesn't deserve any type of redemption and that Kohei Horikoshi shouldn't even be attempting to do so, with fans going so far as to post death threats and wishes on social media to try and dissuade him from doing so. Japanese fans actually like how he is trying to change his ways, enough so where he made it to 8th place on the 4th popularity poll, surpassing All Might himself.
When he first released the first chapter of his third manga series, Horikoshi felt it might not stay popular, but carried on with it because he enjoyed it. The series ended up becoming one of the most popular mangas of the modern age.
On a character-related note, Horikoshi has admitted that he never expected Inko and Bakugo to become popular within the fandom. In Bakugo's case, he believed that everyone would hate him, so he was surprised when he saw him winning the popularity polls.
Anti-Climax Boss: Setsuna in the Joint Training Arc was built up as one of the strongest members of Class 1-B, and Monoma predicted she had the best chance of defeating Bakugo. Her team lost in the shortest match of the arc, without capturing or defeating a single member of Bakugo's team.
Destro's philosophy where a belief in a basic human right or a way to benefit society turns into violence and terrorism has been discussed between fans that can be applied to many political views through history, including Communism, Nazism, and so on. Fans are heavily debating on whether Destro's group and his views are meant to represent any real-life counterpart philosophy or political view or not and even then, which view is exactly being represented.
One can make an overlap between the conflict of the use of Quirks by civilians and real-life gun use and ownership laws. Quirks are heavily monitored and controlled, in line with Japan's own restrictive gun laws. The discussion also mimics real-life debates, where you have characters saying Quirks should be free to use as their users see fit and are a must for protection and self-defense, while others are wary of the problems that can be caused when little or no control is put on something that can cause harm, even when being used for defense. Chapter 300 has a particularly poignant scene where it shows Wash finding an area destroyed because civilians got ahold of support items and tried to fight villains on their own, destroying property and hurting both the villain and other civilians, as the narration mentions the danger of the untrained and unskilled use of Quirks.
A good amount of fans feel that while the Internship Arc is good, it dragged out for too long compared to previous arcs. For comparison, the arc finally reached its end in Chapter 162, for a total of 41 chapters, making it nearly twice the size of the previous longest arc, the U.A. Sports Festival. Among the chapters, it takes a while to actually get to the important parts and several battles are chapters long due to flashbacks being placed in the middle of said fights to explain Tamaki, Kirishima, Mirio and Overhaul's backstories. Even Horikoshi himself noted near the end of the arc that it had dragged on for an unreasonable amount of time. The anime inherited this problem, though to a lesser extent as multiple chapters are adapted in each episode, so an arc that is 41 chapters in the manga is around 17 episodes in the anime. Still, you'll find plenty of fans, particularly anime-only fans, complaining that Season 4 is weaker than the previous three.
Rather than a single arc being the blame, some fans call the entirety of the arcs of 2018 to be at fault of this, due to the year being far too heavy on school and Slice of Life themed arcs that do little to drive the plot forward, such as the U.A. Cultural Festival Arc essentially just wrapping up plot points introduced at the end of the Internship Arc and the Joint Training Arc showcasing the skills of various students and giving Shinso and Class 1-B a long deserved focus, but having almost no stakes and connect very little with the ongoing plot. A very big complaint is that the arc that most moved the story forward, the Pro Hero Arc, was an arc focused on Endeavor and Hawks that lasted only about 10 chapters.
How some feel about the Midoriya vs. Shinso match during the U.A. Sports Festival Arc. The only reason Midoriya was able to break out of Shinso's brainwashing Quirk is due to Midoriya's Quirk suddenly activating on its own, which allowed Midoriya to hurt himself and thus break free of Shinso's control. There's no explanation given for why this happens during the arc proper, with All Might even lampshading that fact ("Don't get too hung up about it!"). While the reason behind this strange event, the fact that One For All has the vestiges of past users embedded into it, does get explained later in the series, that only happens 160 chapters after the battle had already occurred.
In the end-of-chapter notes for Chapter 11, Horikoshi mentions how many were wondering about the discrepancy in terms of the total amount of students in the class. He explains that the number of students mentioned in Chapter 5 was referring to those who passed the entrance exam. The final two students, Todoroki and Yaoyorozu, got in via special recommendations, which is why they weren't counted in the group.
The anime's adaptation of the U.A. Sports Festival Arc basically did this for Yaoyorozu by actually showing off her overwhelming loss to Tokoyami, which was only a single uninformative panel in the manga. This was due to Horikoshi discovering that the length of the arc was ballooning from what he originally intended and cut out some things intentionally because they were one-stroke battles and having them all chew up pages in weekly chapter format would let down the readers. However, while nearly all of the fights Horikoshi cut out are inconsequential, Yaoyorozu's defeat has lasting consequences. Originally, many readers of the manga felt that her broken confidence in the Final Exams Arc came out of nowhere since they never got to see what it was that turned her into a Broken Ace.
For the Bakugo vs. Uraraka fight in the manga, many fans didn't understand why the crowd suddenly turned on the former for full-on attacking the latter despite there being four mixed-sex battles beforehand. This was because the manga didn't show enough to justify this reaction. In the anime, it's shown that the previous fights were a lot more even and in two of them, the girls won pretty easily.note The notable exception is the Iida vs. Hatsume "fight", which is nothing more than a glorified sales pitch for the latter. In the Tokoyami vs. Yaoyorozu fight, it's shown that the former deliberately attacked in a way that would get the latter out of the ring without hurting her. In Bakugo's case, it appears that he has a significant advantage over Uraraka. However, since he doesn't go for a quick ring out, the crowd assumes that he's just taking pleasure in hurting someone who is weaker than him.
In the collected volumes, Horikoshi mentions that some fans were confused about Midoriya using One For All at 1,000,000% in the form of a Delaware Detroit Smash during the Forest Training Camp Arc; he explains that this was just a Battle Cry and wasn't meant to be a literal measure of power.
The Internship Arc collected several complaints about it being "not very MHA-like" and Overhaul for being a bland boring villain, with Horikoshi admitting that it had a very experimental structure and he was trying an arc more like a typical shōnen than his usual Western-inspired structure. The U.A. Cultural Festival Arc has since been labeled as a return to form for the manga, with a nice focus on the Slice of Life aspect of U.A., more comic moments, better paced and a far more interesting villain than the Hate Sink Overhaul in the form of the Affably Evil Gentle and his Genki Girl sidekick La Brava.
A common complaint is that Horikoshi introduces many interesting characters, only to ignore them, instead preferring to add more new characters. Notable examples of this include Shinso, who became a major Ensemble Dark Horse but was relegated to infrequent cameos after the U.A. Sports Festival Arc, and all of Class 1-B, who are mostly forgotten about in favor of Class 1-A. The Joint Training Arc gives both Shinso and all of Class 1-B A Day in the Limelight, with Shinso, in particular, being given a chance to join the Hero Course if he performs well enough (a popular Fandom-Specific Plot). This was later expanded to give time even for less important Class 1-A characters to shine, which include Kaminari showing he is smarter than what people give him credit for, flashbacks of Tokoyami's time working under Hawks and Yaoyorozu's newfound rivalry with Kendo.
Many complained that Midoriya beating Shinso in the U.A. Sports Festival Arc was an Ass Pull since there was no explanation given as to why One For All activated on its own and broke him out Shinso's mind control. The Joint Training Arc would later explain that vestiges of past One For All users still inhabit the Quirk, which is why One For All seemingly activated on its own, which regardless of opinions on if it works or not, at least explains the situation.
At the end of the Joint Training Arc, many feared Midoriya would become extremely overpowered, resulting in the loss of tension for the rest of the story. This was due to the revelation that Midoriya inherited six additional Quirks thanks to One For All. However, the following arc showcases the Big Bad, Shigaraki, evolving his own Quirk, which has enough power to turn an entire city block into a deserted crater, gathering an army, and recruiting Gigantomachia. Due to these factors, many fans fear that Midoriya might be too underpowered now. Likewise, in Chapter 257, Bakugo and All Might conclude that none of the One For All users' original Quirks were all that powerful on their own, which was why none of them could defeat All For One.
When news dropped that Season 4 of the anime would start off with a recap-filler episode like Season 3, the fandom was predictably frustrated. However, when the episode actually aired, many were pleasantly surprised with it. The recap aspect of the episode is fairly understated, and the plot has some nice worldbuilding and fun slice of life moments that the fanbase enjoys. Adding to this, the anime original character introduced in the episode, Taneo Tokuda, is incredibly likable and interesting, with many hoping that he will be brought back in the future.
A significant portion of the fans disliked Aizawa for expelling dozens of students simply for failing his Quirk test, giving them black marks on their records, and leading to some Fridge Logic. Chapter 254 reveals that while Aizawa did actually expel those students, he also re-enrolled them, and the last class he expelled is still at U.A., making the entire exercise a harsh but fair "rational deception" that Aizawa is known for.
The original name for the Doctor, Maruta Shiga, was very controversial, particularly in China and South Korea, due to its unintended connection to an experiment done by Imperial Japan towards those from those two regions during World War II. Horikoshi swiftly apologized for this and changed the name to Kyudai Garaki, a name that retains the original's similarity to Shigaraki (as in, All For One's surname) without the problematic "Maruta" reference.
A long-lasting complaint in the fandom was the fact that Bakugo would not acknowledge that his bullying and mistreatment of Midoriya was wrong or apologize for it. Chapter 284 has him admitting to All Might, though not to Midoriya, that in some way, taking part in Midoriya's training of the One For All is his way to atone, and that he realizes his bullying of Midoriya came from a place of fear that Midoriya was better than him. Chapter 322 takes it a step further. As he and the other Class 1-A students find Midoriya, Bakugo reminds him of what he said about winning together when he saved Midoriya from Shigaraki, and then fully admitted his bullying of Midoriya was wrong from the start, and fueled by his inferiority complex, which was broken down by his first year at U.A. and all he endured. Finally, while he acknowledges that it won't change anything, he bows his head and apologizes for everything.
Mineta has long been The Scrappy of the series for being a one-note pervy character who we're constantly told is intelligent with nothing really to back it up. In Season 5, he has less pervy scenes, and he actually creates strategies and analyzes his opponents.
A recurring criticism was that, for allegedly being the heroine of the series, Uraraka was often left with little to do. Both manga and anime fans would get catharsis in different ways, with the anime emphasizing her being the one to help Midoriya when Blackwhip went nuts as well as taking down half of Class 1-B's team, while the manga gives her an amazing moment where she gives an impassioned speech to a crowd of rioters, getting them to see heroes as people too and let Midoriya come back to U.A. while also breaking Midoriya's emotional dam in the process and getting him to finally stop running. Both moments were praised by fans and are considered to be highlights of their respective arcs.
The series is praised for its detailed art. A notable aspect being how Horikoshi gives even background characters detailed, individual designs. Fans that are artists themselves always point out how absolutely floored they are by Horikoshi's unique skill at drawing hands, mentioning his hands are heavily expressive and realistic and use him as reference for their own art. Funnily enough, the author's note of volume two actually had him discussing drawing hands and how important he feels they are for "showing expression and character."
The anime is done by Studio BONES, well-known for their beautiful animation, and unlike many anime adapted from Weekly Shōnen Jump is released in seasons (or cours) rather than weekly, meaning the studio has far more time to plan and animate each episode. And while it looked good from the start, it has improved considerably since Season 1. The action scenes, in particular, always look amazing, with All Might vs. Nomu, Todoroki vs. Midoriya, the Stain fight, and All Might vs. All For One being stand-outs.
Better on DVD: Or tankobon, in this case. A major complaint about the divisive Internship Arc is the fact that it took an entire year to end, with more than once a delay between chapters due to the health issues of both Horikoshi and his assistants. Defenders of the arc claim that the plot can be better appreciated on a second reading now that the entirety of the arc is available, and that in this second reading, a lot of the problems the readers have are alleviated. In fact, a good portion of the defenders of the arc weren't accompanying it from the start and caught up with the manga midway through the arc.
Captain Obvious Reveal: In Chapter 290, Dabi is revealed to be Toya Todoroki. It had long been considered very obvious to a large section of the fanbase that Dabi and Toya were one and the same due to overwhelming evidence (his fire Quirk, his self burns and poor battle endurance being consistent with Endeavor's descriptions of Toya's weaknesses, his cryptic remarks to Endeavor and Shoto, his generally similar face & hair to both Shoto and a young Endeavor, etc).
Bakugo losing to Midoriya in the Battle Trial Arc. After he had been treating him like trash for years and was extremely smug in his abilities, it's extremely gratifying to see Bakugo's smug grin completely vanish when Midoriya finally gets a win against him. This even jumpstarts Bakugo's Character Development down the road.
Seeing as how much of an annoying, whiny, Psychopathic Manchild Tomura Shigaraki was at the beginning of the series, it's rather satisfying to see him have a mental breakdown over All Might defeating his Nomu in the USJ Arc and then get shot by Snipe multiple times before being teleported away by Kurogiri. His rage over Stain managing to steal the spotlight from him in the Hero Killer Arc can also qualify. Both incidents even start his Character Development into a more mature and calculating leader.
Midoriya punching Bakugo during the Final Exams Arc. Up until that point, Bakugo had been an obnoxious jerk with full intention of failing both himself and Midoriya merely because he refuses to accept his rival's help. The punch not only saves Bakugo from All Might, but knocks some sense into him.
Midoriya using 1,000,000% Delaware Detroit Smash to defeat Muscular is particularly satisfying as the villain proved himself to be utterly despicable by gleefully admitting to murdering Kota's parents and then attempting to kill him just for fun. Not only does this save Kota, but it also ends his hatred for heroes.
All Might smashing All For One into a pulp is easily one of the most pleasing moments, considering how the Symbol of Evil quickly established himself as one of the most reprehensible characters in the series.
Mirio pounding the living shit out of Overhaul. Even after losing his Quirk. There's also much catharsis in seeing 100% Full Cowl Midoriya, aided by Eri, beating the shit out of Overhaul soon after. Not long afterward, Shigaraki attacks the convoy transporting Overhaul where Mr. Compress severs one of his arms. This is followed by Shigaraki using his Quirk to amputate Overhaul's other arm, thereby preventing him from using his Quirk. Shigaraki then taunts Overhaul, relishing how he now has the upper hand over him and lets him live as a crippled and broken man. It's a rather satisfying dose of Laser-Guided Karma for one of the more monstrous villains in the series.
Although he was trying to become a better person, it's still satisfying to see Endeavor getting beaten down by Hood and getting a nasty scar on the left side of his face, similar to the one he indirectly inflicted on Shoto. The latter even makes a snarky remark about it. And to top it off, he gets a scathing Calling the Old Man Out from Natsuo, another one of his children, about his awful behavior, even if he is trying to become a better person.
In Chapter 322, Bakugo finally apologizes to Midoriya, even using his real name, for all the hurtful bullying he put him through over the years. The fact that the culmination of his Character Development is not some great triumphant battle against a powerful villain, but rather bowing his head and saying sorry for his actions and admitting that he was wrong, more than any other moment he has had, this proves Bakugo has truly changed and become a better person.
Midoriya has been shipped with a delicious pork cutlet bowl. It's also popular to ship him with a hospital bed.
It's not uncommon for fans to ship Todoroki with zaru soba.
For some reason, Mineta has been shipped with LSD. Yes, the drug.
Cliché Storm: Some have pointed out that the manga's overall plot and format matches up pretty cleanly with the rest of Shōnen Jump's repertoire. However, Tropes Are Tools, and it may make My Hero Academia all the better for it. For examples, look at this page.
Goto Imasuji, better known as "Muscular", is a sadistic supervillain with a Quirk that allows him to control his muscles and augment his body. Caring only for bloodshed and murder, Muscular attempted to massacre a town before being stopped by the hero duo Water Hose. Torturing and killing the two, Muscular later tries to murder their young son Kota for fun. Later released from prison, Muscular attempts to rampage across numerous towns and cities to massacre any civilian he can find, rejecting any overture from Izuku Midoriya and stating he only cares about indulging his appetite for murder.
Vigilantes: Kuin Hachisuka is a Quirk-using queen bee, and dealer for the dangerous Quirk-enhancing drug, Trigger. Prior to the story, Kuin critically wounded the wife of Knuckle Duster and invaded the mind of his daughter, Tamao Oguro. Using Tamao as a host, Kuin regularly invaded homes and murdered their residents to take them over, regularly changing homes to find more victims whenever she got bored. Kuin introduces herself by using her Quirk, Queen Bee, to infect several innocent civilians with Trigger, causing them to go on rampages while in constant pain. She later convinces the ruthless vigilante Stendhal to attempt to murder young delinquents who previously used the drug. For no reason other than her amusement, Kuin attempts to cause a bus filled with passengers to crash, complaining how boring it would be if there were no victims when the hero Ingenium saves them. She also uses her bees to possess a classmate she befriended, having them burst out of her body to attack the delinquent, Souga Kugizaki, wounding if not killing her friend. When she hears that there'll be a concert that Pop Step is a part of, she has a monstrous electric eel, formerly a regular young man who Kuin kidnapped and experimented on, to cause a blackout, intending to infect everyone at the concert with Trigger. When cornered by Knuckle Duster, Kuin attempts to detonate several of her explosive filled bees, knowing that the recoil she'll suffer will kill Tamao.
Fans have shipped Midoriya with Mitsuki Bakugo, considering how attractive she is, due to the easy interpretation that she could be a cougar, and for the sheer hilarity of imagining Bakugo's reaction.
Due to some various theories about Midoriya's father, specifically that he is the son of a villain, some people started shipping Inko/All For One and Inko/Dabi, following the theory that Midoriya is the son of one of them.
Despite the fact that the mere existence of the idea is pure No Yay for most of the fandom, there are a number of fans that legitimately ship Mineta with some of the female characters. The most popular characters shipped with him being Yaoyorozu, as she's the most attractive student in the class and near-constantly shows off skin, and Tsuyu, as early on the two had a decent number of interactions between them.
Midoriya earned the title of "The Absolute Madman" for his capacity of withholding inhuman amounts of pain to come up with insane plans and moves in order to defeat his opponent. In-universe, there have been times where characters question his sanity based on his crazy plans that always end up working, especially considering he is willing to destroy himself in order to help others. A special mention goes to using Eri's uncontrollable rewind Quirk to use One For All at 100% and hurt himself in the same speed she is rewinding him, therefore suffering no injuries while neither being erased from existence.
Hatsume is a borderline Mad Scientist who dedicates every waking moment to the creation of machines that would be better fitting on a giant robot series than this one. This is amazingly shown in her fight against Iida, where she manipulates him into using her inventions and drags the fight to show everything off while making him dash around the area like a puppet.
Creator Worship: Horikoshi has received high amounts of praise for his outstanding writing, to the point that some fans consider him the author that is going to set the ground for or completely eliminate the clichés that several fans disdain in shonen.
Tomura Shigaraki at first appears to be a psychotic, heartless monster. However, once his horrific past comes to light and it's revealed All For One molded him into his successor simply because he was his nemesis Nana Shimura's grandson, it's not hard to see how he turned out the way he is. Even Midoriya feels sorry for him. It doesn't help that it's implied the real reason All For One took him in is so he could possess his body.
Dabi gets a bit of this once he's revealed to be Toya Todoroki. All he ever wanted to do was to impress his father Endeavor by surpassing All Might as the number 1 hero. However, when it was revealed he didn't possess his father's constitution, Endeavor cast him aside in favor of Shoto. Toya attempted to prove to his father that he could still become the number 1 hero, but an accident covered him in scars and resulted in his family thinking him dead. Becoming Dabi, he vowed to ruin Endeavor's life to make him feel the same pain he felt.
The end of the Shie Hassaikai Arc and his entire appearance in the Tartarus Escapees Arc actually manages to do this for Overhaul. Although what he did to Eri was absolutely monstrous, it's surprisingly hard not to feel a little bit of pity for him. His foster father, the one person he truly cared for, is stuck in a coma, albeit the one he put him in, and he can no longer take him out of it due to having lost his powers. Upon realizing this after losing his arms, all he can do is scream in agony and sadness. In prison, he's been reduced to a shell of his former self: a weak, broken man who only wishes to apologize to his foster father. Him breaking down crying while wanting to see his "pops" again actually manages to be rather sad despite him bringing it on himself.
To some of the fandom, the fact that Bakugo doesn't seem to actually realize that bullying someone and using violence to solve problems is bad, consistently shows little to no interest in actually helping civilians, and only wants to be a hero because he sees heroes like All-Might as "winners" and villains as "losers" and only wants to fight for the winning side really paints him at best as a gray moral character, at worst like bully who just wants to pick socially acceptable targets to beat up on. Even more importantly, people in-universe believe he is this, which is why the fact he decided to tell the League of Villains to shove their invitation up their ass and didn't go the "Rival Turned Evil" route that looked all but actually written on the wall took many characters by surprise.
Mineta, while a hero-in-training and treated as one of the good guys, showcases no heroic traits whatsoever, even less than Bakugo. He only wants to be a hero so he can be seen as being cool and get girls, is inappropriate to his peers, especially the female ones, he isn't courageous, altruistic, smart, charismatic, kind, or any of the traits that the rest of the class is praised as great heroes to be for having, even though he keeps being lumped together with others in this category. Many fans wonder how he got into Class 1-A and why no one has kicked him out yet. The fact that his 5/5 Intelligence stat, higher than Genius Bruiser Bakugo and Badass Bookworm Midoriya, and second only to Yaoyorozu's 6/5 Intelligence has been of no use whatsoever (or even showcased past Informed Attribute) does not help his case.
Aizawa is seen as this by his detractors. He's a deconstruction of the Sink-or-Swim Mentor, but a lot of people see his methods as either ineffective or downright cruel. He is willing to expel entire classes, and has done so before, should they not meet his standards, and would have done the same to Midoriya had he not impressed Aizawa at the last minute. While it's later revealed that the expulsions were temporary, they still go into the student's permanent record. He repeatedly uses "rational falsehoods" to get the students to work harder, but it in turn just scares the crap out of them. He's so incredibly militant about stomping down on all hope or love for the job for the sake of trying to adapt his class to the harshness of Hero life (read: it may get them killed and "sometimes you can't save them all") that when other teachers arrive the kids look like zombies, so dour he's made them. He tends to miss important details regarding the behavior of his students or punish them when he does notice.note Including failing to notice Iida signed up to intern in Hosu, where Stain was last sighted (especially considering that someone who made it to the semifinals of the sports festival could have gotten a more prestigious hero agency than Manual's); thinking Midoriya and Bakugo would become Fire-Forged Friends by facing All Might only for their relationship to remain volatile and All Might almost crippling them; failing to notice Bakugo suffered issues from being kidnapped and being made to take a test that replicated the Kamino incident leading to his fight with Midoriya, then punishing both of them for the fight. He also perpetuates the controversial aspect of hero society by threatening to punish the students for acting without licenses, namely by saying he'd have expelled the entire class outside of Bakugo, Jiro, and Hagakure for either attempting to rescue Bakugo themselves or for knowing about the attempt and not stopping them. Many end up seeing him as both a horrible teacher and a Knight TemplarRules Lawyer in the process. He even mentions that Vlad King, the homeroom teacher for Class 1-B, is a far better teacher than him, as Class 1-B's teamwork is on par with Class 1-A's despite the former's relative lack of life-or-death experience.
Bakugo gets this the most. If Uraraka, Midoriya, or Kirishima aren't being shipped with him, then he is often an abusive jerk who can even take pleasure in their misery and constantly push them towards Midoriya, Todoroki or Kaminari's arms, respectively. At worst, there is plenty of rape-related material of him, particularly with Midoriya. This treatment and especially the rape fics are a bit of a sore point to Bakugo/Midoriya shippers.
Although far rarer, Midoriya can get this from those who ship Bakugo with other characters (particularly Todoroki, Uraraka and Kirishima). He is either an annoying Gary Stu that Bakugo is justifiably pissed at, a possessive and aggressive Yandere for Bakugo seeking to end all competition, or just a past relationship that severely messed up either Bakugo or whoever he is trying to date.
Todoroki gets this from Bakugo/Midoriya. Though he isn't portrayed as an outright jerk as much as someone so protective of Midoriya, he gets in Bakugo's way. Particularly, he is prone to believing Bakugo is abusing Midoriya in one way or another and get in fights with him because of it.
Hisashi gets this a lot from All Might/Inko shippers. He is often a man who abandoned Inko and his own son rather than just working overseas, leaving a depressed Inko behind to care for their Quirkless son, and All Might comes up to pick up the pieces and become the father the family needs.
Kaminari got a bit of this from Jiro/Yaoyorozu shippers in the leadup to the war against the Paranormal Liberation Front. After Midnight tells him that if the thought of protecting everyone is too difficult for him to wrap his head around, he should instead think about protecting the person dearest to him, and Jiro immediately comes to his mind. While the Kaminari/Jiro pairing had existed before then, it wasn't seen as that much a threat to the Jiro/Yaoyorozu pairing due to Kaminari often only being teased by Jiro. After this bit of obvious Ship Tease, however, many fans of the former pairing began subjecting Kaminari to this thinking that the series was heading towards the latter pairing.
Stain. In-Universe, even. His Motive Rant made its way onto the Internet, where it rapidly gained popularity. In addition to inspiring multiple villainous figures, several heroic characters admit to admiring his conviction. There's even merchandise fashioned after him that's available to the public. Out of universe, while he has valid points about the shortcomings of the current hero system, he ends up attacking or even murdering heroes who fall short of his standards, like when he ends the genuinely heroic Ingenium's career, and nearly kills Ingenium's younger brother (who, while blinded by revenge, came to his senses with Midoriya and Todoroki's help).
Shigaraki has his fair share of fangirls, especially after his woobie traits have been revealed. A lot of his fans went on to forgive his murderous rage against a bunch of fifteen year olds because of this.
Toga is a wanted serial killer, but she's also an adorable Yandere high schooler, so naturally she has tons of fans. She, however, generally averts this, as no one expects her to become good. The only difference from her portrayal in the manga to the portrayal in fanworks is that her yandere-ish behavior is played for fanservice rather than horror.
Bakugo gets this treatment from some fans, particularly those who ship him with other characters (Midoriya in particular, but to a lesser extent when he's shipped with others as well). Midoriya seems to be guilty of giving this treatment to Bakugo as well if you consider he always goes out of his way to excuse Bakugo's behaviour towards him. It's also common for some fanfics to portray his relationship with Midoriya, when not romantic, infinitely more amicable than what it really is, sometimes even as Vitriolic Best Buds, and both of them often recurring to each other as an advisor or confidant. A particularly odd little trend that's especially popular on Tumblr is claiming that Bakugo's anger at Midoriya is completely understandable, if not justified, as Bakugo spent years training with his Quirk and becoming stronger so he could reach the top only to be usurped and ultimately end up in the shadow of his rival who was once powerless. This completely ignores the fact that Bakugo bullied Midoriya viciously before Midoriya inherited One For All and also comes with the rather disturbing side-effect of making it sound as though the continued bullying afterward is Midoriya's fault.
Dabi has his fans if only due to Evil Is Cool and his interesting design. The theory that he's related to Todoroki and/or Midoriya has also helped somewhat (as many expected, he's Endeavor's son Toya). His fans somewhat expect him to get revenge against Endeavor and get away with it.
Gentle and La Brava got this a lot. While both of their stories are tragic and sympathetic, people often ignore the fact that they are still criminals. Some even go as far as say that Midoriya is the one being the jerk in that situation for not letting Gentle go on with his dream and that he is the true hero there. However, Gentle's selfishness has also been pointed out, as he admits to be willing to destroy Eri's chance at learning how to smile, as well as all of the work that the heroes-in-training put into the U.A. Cultural Festival, simply just to get some sort of attention.
Endeavor. Since the start of his redemption arc, many fans have taken to glorifying him and generally demonizing all of his family.
On the other side of that fence, Rei Todoroki also gets some of this. While she's undeniably a victim of Endeavor's abuse, some fans act as though she's purely a victim and ignore or gloss over her dumping boiling water on her five-year-old son's face. Some go so far as to claim that she shouldn't have experienced any consequences from said action.
To a minor extent, but though he does care about them, Aizawa can be a real jerk to his students at times, but his more diehard fans tend to excuse every single thing he does/says towards them, even when he's being way harsher than he needs to or messing with them for his own amusement.
Dry Docked Ship: Endeavor/All Might, in no small part due to some beliefs that they studied together, and Endeavor had an obsession with him starting there.
There's almost no clues over who the U.A. traitor is, and no arc has particularly focused in figuring out who would it be, even though a traitor is mentioned periodically, leading to this. At this point, there are theories pointing towards any teacher at U.A. except All Might and a good chunk of the students, particularly Kaminari,note Exacerbated by him seemingly doing the Meta Liberation Army's hand sign in Chapter 241, and his freakout over finding himself among the heroes on the front lines in 259. Shoji, Hagakure, and Uraraka. The Wild Mass Guess page even lists the potential candidates among the tropers. That's not even getting into the theories that the traitor plot is a Red Herring concept being used to drive the heroes into paranoia.
Another popular theory is that Dabi is one of Shoto's brothers, specifically the unseen yet mentioned Toya Todoroki. The first hint is his Playing with Fire Quirk. The second hint is that he shares the same haircut as one of his siblings seen in the flashback from his childhood, though a different color. The third hint is that he's rather adamant about not using his real name, and that it would make sense that somebody from a family as prestigious as the Todorokis would hide his identity. The fourth hint is that during the Forest Training Camp Arc, he had a rather specific interaction with Shoto, almost like as if they've met before. The fifth hint is him sharing the same greenish-blue eyes as Shoto's fire side. Some speculate the reason he worships Stain is because having Endeavor for a father would twist his view on heroes, and that the reason Shoto didn't recognize him is because he dyed his hair and his patches made him harder to recognize. Finally, it's revealed that Toya had a fire Quirk even stronger than Endeavor's, but was too physically frail to use it to its full potential; Dabi's Quirk uses blue flames, indicating they burn hotter than Endeavor's, and Dabi's biggest weakness is his physical frailty and lack of resistance to his own fire. It is confirmed that Dabi is indeed Toya Todoroki, Endeavor's eldest son, who has returned to destroy the Flame Hero.
Another prominent theory is that Midoriya wasn't actually Quirkless. Instead, his Quirk was stolen by All For One. All For One's back alley doctor's silhouette highly resembles Dr. Tsubasa, the doctor who told Midoriya that he was Quirkless, and it was later revealed that Dr. Tsubasa is actually the grandfather of the winged boy, Tsubasa, in Bakugo's Gang of Bullies, who was heavily implied by Horikoshi to be the Winged Nomu that grabbed Midoriya during the Field Training Arc. This creates a huge degree of Fridge Horror, since it effectively insinuates that Dr. Tsubasa either lent a helping hand to All For One in having Tsubasa's Quirk stolen, or he allowed Tsubasa, his own grandson, to be turned into a Nomu. The anime further fuels this theory due to Dr. Tsubasa and All For One's shadowy doctor having the same voice actor in both the Japanese and English versions. Revelations later in the manga made this theory stand out much more heavily, with it being revealed that Ujiko, said shadowy doctor, did manage to steal Quirks before All For One helped him out, meaning it's entirely possible that this theory is more likely true than before.
Virtually everything about Hisashi Midoriya, due to his absence from both Izuku and Inko's lives and the narrative leaving many things open about him:
Some believe that Hisashi is the reason why Izuku doesn't have a Quirk, due to some unexplained issue with him, and wonder if his distant relationship with his family is connected to that. The very disturbing idea that he might actually be Dabi is also brought up, too, considering that Dabi has not revealed his true name and possesses a strange fire Quirk, while Hisashi is said to be a fire-breather by his wife, though this theory has slowly died down as the "Dabi is a Todoroki" theory increased in popularity. The Reveal that Dabi is in fact Toya has officially killed that idea.
There are theories suggesting that Hisashi is All For One himself, based on small oddities, the inspiration that All For One visibly takes from famous Big Bad DadDarth Vader, and the one partial shot of his intact face in profile - the only view of his pre-injury face we are ever given - which reveals facial features eerily to Izuku's and similarly messy hair, in an otherwise Cast of Snowflakes series. Some have taken this theory and ran with it in regards to fanfics, such as the Conversations with a Cryptid series.
Quite a few male characters have strong female fanbases. Todoroki and Bakugo are the most prominent in Japan, but according to Horikoshi, Sero also has a lot of lady fans. In the West, All Might, Aizawa and Endeavor are a very popular subject of self-insert ships.
Kirishima's adorable "manliness" also nets him this. Iida also got one after the Swimming Pool episode reveals that he's jacked like a bodybuilder, sporting a full 8-pack.
Hawks as fans have pretty much fallen in love with him ever since he first appeared, and he even placed fourth in the latest popularity poll over other fan favorites like All Might and main characters like Iida. While part of it is due to his role in a very well received plot, a lot is also about from his really good looks and being comparatively much younger than the other pro heroes, who tend to be in their late twenties if not much older.
Cementing his Ensemble Dark Horse status, Shinso also owns an unexpectedly large female fanbase, as the countless fanworks (up to having an entire fanzine dedicated to him) and self-insert fics attest to, mostly because of his Heroic Resolve to do good despite owning a villain's Quirk, his Aizawa-like personality and looks, along with his Power Perversion Potential for being able to control people against their will.
Everything about "Hero Killer" Stain is basically the embodiment of a '90s Anti-Hero, except he's a villain. He's a vicious Knight Templar who's convinced that none of the current group of Heroes barring All Might (and later, the main character Deku) are "real heroes" and need to be purged. He's also a complete psychopath with a warped view on what being a hero is and has no compunctions against murdering teenagers. However, because of his design, weapons and powers as well as the ludicrous degree, he'll keep on fighting (after being defeated, he still continues trying to fight against the other heroes with a punctured lung and scared them enough to make them flinch before he passed out, while standing up) earned him admires in-universe and out. The League of Villains take advantage of this and recruit a plethora of new members who wished to follow in Stain's footsteps.
Stain in this case did a lot to help the League of Villains more than he realized, as the League of Villains truly got some really badass fighters like Spinner, Dabi, and Toga, who all agreed with his ideals to purge Japan from the 'fake heroes' festering the hero society, gaining them a lot of fans.
Shigaraki has gotten this in spades after his talk with Midoriya and realizing his own convictions which kickstarted his development from a Psychopathic Manchild into a genuinely cunning and dangerous villain. For any that still had doubts about him, his focus in the Meta Liberation Army Arc seems to have done the job of truly establishing him as a terrifying villain to rival All For One.
Evil Is Sexy: Oh, like you wouldn't believe. Expect nearly every villain in the series to have some sort of sexual appeal.
Toga is a crazy, bisexual Yandere who has a fetish for blood and seeing people getting beaten to a pulp. To many Nightmare Fetishist fans, she comes across as being extremely attractive because of this.
All Might/Inko became a popular pairing after Chapter 97 after the former admitted he admired her, not only for her resemblance to his deceased mentor, but her personality too. Despite Inko being canonically still married to Izuku's father, several fans prefer to simply ignore this fact either by portraying All Might as Izuku's father or Inko as being divorced. This is helped by said father being The Ghost.
Despite Endeavor being married to Rei, although this is not played for romance, All Might/Endeavor started sparking in some circle after Season 2 of the anime. Fans of the ship tend to believe that Endeavor's obsession for All Might has romantic and Armored Closet Gay undertones.note A common theory is that the two used to date before a huge fallout led to a bad break up. Also helping matters is the fact that Endeavor's marriage to Rei had nothing to do with sexual or romantic attraction, and in-universe was for the purpose of conceiving an heir, meaning Endeavor's marital status is not necessarily representative of his sexual identity. Since the Pro Hero Arc, however, Hawks/Endeavor became this.
Despite not getting as much Ship Tease as Kaminari/Jiro or as many obvious hints as Midoriya/Uraraka, Shoto/Momo is a definite fan favourite and often the only non-Yaoi you will see Shoto in, mostly because he doesn't talk much to any other female in the show. Indeed, both deeply respect one another and Shoto gradually opens up more often to Yaoyorozu who admires him sincerely.
Fan-Preferred Cut Content: Yaoyorozu's Quirk turns her body fat into solid objects, such as blankets, radios, and cannons. As a result, her hero costume needs to be skimpy. In the finished product, this is a costume with Absolute Cleavage. This design has proven controversial, as she's a teenager and the costume comes off to many as being too sexualized. Many fans find her original sports bra and shorts-like design to be a lot cooler and more appropriate, making them wish it hadn't been changed.
Fandom Heresy: Calling out Inko for having gained weight since Izuku's childhood. A lot of fans don't take kindly to people saying she has become ugly or unattractive due to gaining weight and put down those who say it by pointing out that it would be perfectly normal for a (technically) single mom to do such a thing.
An interesting case happened with the fandoms that were rivals to the Naruto fandom. Because of the manga's status as the Spiritual Successor to Naruto, fans who disliked the manga tend to associate both way too much and believe that My Hero Academia has the same problems Naruto had despite never reading it. Additionally, there are some former Naruto fans who feel that this series executes the tropes the former tried to pull off much better.
As the two works competing for being the post-Naruto new apple of Shōnen Jump's eyes, Black Clover fans tend to have a bone to pick with My Hero Academia fans, generally accusing the latter work of having just as many clichés. This was intensified when the former work got an anime that started being heavily pushed by Crunchyroll to become the next Naruto, while said anime also got a lot of nasty commentary and was criticized for its unhinged use of shonen clichés and Asta's voice. Black Clover has gradually come to be seen as "the new Bleach", which has only furthered the rivalry.
A really unusual case with Boruto: Naruto Next Generations which, much like its protagonist, has gone to painstaking efforts to make it clear that while it is a successor to Naruto, it is a distinct entity with its own way of doing things. While most people were perfectly content with this, a number of Naruto fans within the My Hero Academia community began taking shots at Boruto for being inferior to My Hero Academia, which they view as a more faithful successor. This has since instigated a larger mutual rivalry between fans of both series.
Crunchyroll's Anime Awards would cause many fandoms to turn against the My Hero Academia fandom, believing the series to have an overblown and unearned popularity that doesn't reflect its quality, which causes the series to earn many awards despite other shows deserving it more. In 2018, Rascal Does Not Dream of Bunny Girl Senpai's fandom was particularly angered at My Hero Academia for feeling that their protagonist, Sakuta, was infinitely more deserving of the Best Boy Award that ended up going to Midoriya. Some of My Hero Academia fans argue that at least this series has more staying power than others, and dismisses them, as well as their fandoms and complaints, as passing fads that are forgotten by the next popular anime of the following year.
The universe of the series is a rich and fertile soil to create OCs of both pro heroes and students.
As of Chapter 96, all students are being asked to move in to the school dorms. Essentially, this opens a huge space for slice-of-life and ship related fanfics as the students from Class 1-A are now dormmates.
For the second popularity poll, Horikoshi drew the top 10 characters in a fantasy theme across a large two page spread. The image quickly caught on with the fandom, and gained even more popularity after it was used as a basis for the third ED of the anime. As a result, numerous amounts of fan art and fanfics were created of the characters in an RPG-esque fantasy setting. Subsequently, the AU became a sort of recurring thing in the official material, it was the setting for a chapter of the spin-off light novels and the theme again for the fourth popularity pool drawing, as well as getting a shout out to it in the anime itself.
A few promotional images in the Halloween showcased several characters in costume outfits.note Midoriya as a ghost, Bakugo as a werewolf, Iida as a Frankenstein's monster, Uraraka as a witch, Todoroki as a vampire, Kaminari as a devil, All Might as a skeleton and Aizawa as a mummy. This has become a source of fanart and fanfics of the characters wearing these outfits in halloween or an alternate universe where they're all these kinds of monsters. Sometimes this even happens together with the fantasy-themed fics above.
How is the rest of the world handling Quirks? You tell us!
Fanon Discontinuity: The fact that Inko is still married to Izuku's father is a fact known, but mostly ignored, due to a large preference for Inko to be with All Might. Others also add in their theories about Izuku's father being a villain, possibly even All For One himself, to explain why she wouldn't be with him.
Bakugo/Midoriya is this since Bakugo played the Arc Villain early on and was his rival, though this no longer applies. The same logic can be used on Todoroki/Midoriya, for Todoroki's part as the rival in the U.A. Sports Festival Arc.
Midoriya's status as Launcher of a Thousand Ships, besides the popular Alternate Universe of him as a villain makes ships of him with members of the League of Villains, including Shigaraki, Dabi, Toga and even Stain and All For One.
Fans have taken up shipping Bakugo/Toga, though it doubles as a Crack Ship due to the fact that they haven't directly interacted during his kidnapping. They most likely do this due to Bakugo's Japanese voice actor saying he considers Toga to be attractive.
All Might/Endeavor is sometimes shipped, despite the fact Endeavor despises All Might.
Midnight/Mt. Lady, who are known to have gotten into a Cat Fight on TV, are shipped together due to their fiery dynamics.
Hawks/Dabi, which was surprisingly popular even before their actual interaction in Chapter 190/191, was only furthered when they actually showcase a very antagonistic relationship.
At the beginning of the manga, a lot of praise was given to the manga's pacing, with villain-centered arc driving the plot forward interlaced with school-centered arcs that drove the characters and the addition of a multitude of vibrant, interesting characters in each arc. Eventually, some fans started to complain about these exact elements. These fans believe the amount of school-centered arcs has led to the plot advancing at a snail's pace and leaving enough unresolved plot threads to weave a blanket, while the sizeable cast has become sizeable enough that most characters will never get any focus, no matter how much fans want.
Ironically enough, this has started to go in the opposite direction, as while the story is moving at a faster pace after the Paranormal Liberation War arc, it has also resulted in a lot of story concepts and characters feeling extremely rushed or woefully underexplored. Some examples include the evil side of the Hero Safety Commission via Lady Nagant's backstory, the developing of One For All's other quirks and their relation to Deku's emotional state (with each subsequent Quirk after Black Whip being developed at increasingly absurd speeds despite their initial difficulty), Deku's solo vigilante arc and his degrading mental state from his self-destructive behavior, the loss of the Hero System, etc.
Some of the more contentious points of the Internship Arc, such as most of the cast being pushed aside in favor of new characters, were present in the Field Training Arc. Back then, however, it wasn't as much of a problem because that arc was much shorter, most of the cast who wasn't shown came back having learned new things in their absence, and there were fewer new characters.
With One-Punch Man because of how both series are Japanese takes on the Western superhero genre. This has created a significant overlap in the fandoms rather than a rivalry. The fact that One-Punch Man is a seinen with a much older target demographic and more adult humor than My Hero Academia helps. Heck, it's to the point where some jokingly suggest that One-Punch Man is a Distant Finale for My Hero Academia, with Saitama being the final/current user of One For All.
The fandom is on friendly terms with ONE's other series Mob Psycho 100 due to both shows featuring socially-awkward but powerful kid protagonist. There are many fanarts and fanfic where both protagonists befriend each other or Mob himself being depicted attending U.A. to train his telekinetic powers.
There's one with Naruto. Horikoshi has cited Naruto as one of the inspirations for the series, and it started around the same time Naruto ended, so the timing was good for fans to find a new series to fill the void. This is exemplified by this fan-made comic.◊ Now with an updated version in color.◊
Both My Hero Academia and Sailor Moon have a great friendship. Additionally, there are some fans who wished to have Midoriya and Usagi show up in some crossover fighting games like BlazBlue: Cross Tag Battle.
A small one with the Disney cult movie Sky High, since the manga is basically a Japanese version of it.
It has one with Tiger & Bunny, due to both being anime series about Western-style superheroes.
It has a pretty big one with Little Witch Academia, largely due to similar ideas behind the plot, youngster with a dream and a natural lack of skill for what they want to do (Midoriya and Akko) gets to follow in their hero's footsteps (All Might giving Midoriya One For All, while Akko receiving guidance and the Shiny Rod from Ursula) at an academiaof adventure where said hero teaches. A lot of crossover fan art of Akko in U.A. and Midoriya in Luna Nova was prompted soon after Little Witch Academia's airing ended.
Fans of Bungou Stray Dogs are friendly with My Hero Academia fans and/or have watched My Hero Academia as well due to the similar setting of powers though the former are more in line with the supernatural. It is another common fandom for crossovers in fan works.
There seems to be one with Dragon Ball, as indicated by the fact that the majority of "You Say Run Goes With Everything" videos are Dragon Ball-related.
There's one with JoJo's Bizarre Adventure, due to how many references and similarities there are. Like with Dragon Ball, a lot of the "You Say Run Goes With Everything" videos are synced to moments from JoJo.
With Haikyuu!!. There are actually several voice actors who voice significant (whether they're main or popular) characters on both shows.
Among Western YA reader's there's some overlap between this series and the Renegades Trilogy by Marissa Meyer due to having similar settings and world building. Even the same criticism's of a world where superheroes run rampant. Nova's motivations and criticisms of her world are remarkably similar to Shigaraki's.
Aoyama's defeat at the U.A. Sports Festival, which comes after his belt gets destroyed. It's a lot harder to laugh at after it's revealed that he suffers from a condition where his body can't handle his own Quirk without it, and said condition also causes occasional Power Incontinence.
The omake where Mt. Lady makes fun of Midnight by calling her old is Played for Laughs, especially when the argument devloves into a Cat Fight. It becomes a lot less funnier when Midnight dies at a very young age (at most in her early 30s) in the Paranormal Liberation War.
In Chapter 172, Tokoyami briefly mentions with sadness about his failure to master the F Chord. The F Chord is a very difficult chord to be played by people who are just learning to play guitar, as anyone who has tried to can say.
The types of mushrooms Komori grows during her fight in Joint Training Arc:
Ionomidotis Frondosa and Coprinopsis Atramentaria are mushrooms which are completely black and partially black, respectively, which makes them a perfect hiding place for Kuroiro.
Schizophyllum Commune is known to cause diseases affecting the Respiratory System, and it's what Komori grows in Tokoyami's throat.
While the manga is already popular in its native Japan, it's much more popular in North America, thanks to being a perfect mix between Japanese battle shonen and American superhero comic books, where it's one of the few mangas to have reached mainstream popularity.
In regards to characters, both Gran Torino and Stain placed noticeably higher in the American popularity poll than in the Japanese one.
Hatsume is an example of this. In the Japanese popularity poll, she ranked lower than Kendo, a character who at the time had less screentime than her. In America, however, she's a favorite among fan artists.
An example with a character that is already popular with both sides of the fanbase in Tsuyu. In Japan, Tsuyu ranked in 6th place in the first popularity poll and dropped done to 9th place in the second. In the U.S. poll, she was 2nd place for the first and 5th in the second.
There's Toga, who placed 19th in the second Japanese poll, but 3rd in the U.S. poll.
Mirio is way more popular in the West than he is in Japan. In the 3rd and 4th popularity polls, he ranked 41st and 26th, respectively, whereas many Western fans have him on their list of favorite characters of the whole series. The latest Western popularity pool ranks him on the 9th place, 17 positions above his ranking in Japan.
Gotta Ship 'Em All: Due to Loads and Loads of Characters, and them all frequently being paired up with each other in various battles and activities, shipping has run pretty rampant in the fandom with sexuality rarely being a consideration.
The series starts to pick up steam with the USJ Arc. For others, the U.A. Sports Festival Arc is where it started because of the Character Development that occurred. For how the villains were written, the Forest Training Camp Arc helped with that.
Season 2 is definitely when the anime started to get more popular. While Season 1's ratings were good, Season 2's ratings for the most part kept landing it in the top ten spot, with a recap episode actually having better ratings than the final episode of Naruto: Shippuden. On top of that, the series' burgeoning popularity was so strong that Season 2 was doubled to a 26 episode run as opposed to a fleeting 13 for Season 1, appeasing viewers who got annoyed with the idea that they were waiting a year for only 13 more episodes to come out. And the announcement of Season 2 immediately followed the end of the Season 1 finale to keep viewers invested and assure them the series was not going to be dropped. Moreso, it coincided with the return of the equally wildly popular Attack on Titan, which had the opposite fate- shaved down to a half-length season (though with the other half airing next year as a guaranteed third season to get a rhythm going again after a four-year deep freeze on production). Viewers of that series were consoled by the fact My Hero Academia would fill the void and flocked to it.
While the series hasn't shied away from portraying its antagonists in a sympathetic light, the Meta Liberation Army Arc completely eschewed whatever was left of its original Black-and-White Morality in favor of a more mature, nuanced worldview. In the process, the League of Villains has developed into protagonists in their own right. Subsequently, the manga had a darker tone and a tenser atmosphere that many fans saw as a great improvement over the arcs with divisive receptions that happened before it (like the Internship, U.A. Cultural Festival, and Joint Training Arcs).
When Midoriya's attempt to attack the Sludge Villain proves ineffective by itself, and he only escapes because he shamed All Might into acting, he ends up getting chewed out by the heroes after the incident is resolved. Gentle, as Midoriya's Evil Counterpart, was similar in that he tried to save someone, only to fail and inadvertently make things worse. If Midoriya hadn't been as lucky as he'd been, his life and reputation might have been ruined if he'd been judged to have interfered with a hero's work.
When Twice was introduced, his goofy antics and odd mannerisms quickly made him an Ensemble Dark Horse, with many fans pointing to Deadpool as an obvious comparison and inspiration. Come Chapter 115, we get to see him without the mask, and we find out that his antics are a side effect of having been mentally broken through suffering an Ambiguous Clone Ending... of his own doing, due to misuse of his Quirk. Behind the mask is a terribly conflicted and self-loathing man suffering from a split-personality who doesn't even know if he's the original.
Less than a week after the anime gets to where All Might loses his powers and his position as #1 hero, we get Chapter 188, which ends with his successor, Endeavor, suffering a really bad injury. It really makes his "You're next" line unfortunate.
In Chapter 160, Dabi refers to Spinner as "Lizard," which Spinner takes offense to. In Chapter 220, it's revealed that for most of his life, Spinner has been discriminated against due to his appearance and labeled as "Dumb Lizard Man" by people with antiquated values. The same information also puts some details about Tsuyu and Shoji's past into a much harsher light, such as Shoji having to hide his face to not scare others, seemingly never removing his mask, and Tsuyu having a hard time making friends because she was ostracized from the other girls' circle of friends.
The Shie Hassaikai wear Plague Doctor masks to emulate their germophobic leader, and Yu Hojo of the Garbage Trio wears a standard surgical mask. In the COVID-19 pandemic, mask-wearing became a much more common practice to help contain the spread of the virus.
Jokes about Shigaraki's hand-themed design, calling him "Handyman", "Handjob" or "Facepalm", get a lot darker when Chapter 222 reveals that those hands are all that are left of the family he accidentally killed with his Quirk.
Belief both in-universe and out that Mirio was a more worthy holder of One For All was rendered this in Chapter 304, where the previous holders of One For All acknowledge that Midoriya was the perfect choice for being the holder of One For All due to his Quirklessness. Mirio, or any other Quirked individual, would die roughly 20 years after gaining it due to having it along with their original Quirk forcing their body to engage in Rapid Aging.
Every instance of characters like Bakugo and Aizawa telling Midoriya he doesn't belong in U.A. High and that he should leave becomes this after the Paranormal Liberation War, since Midoriya is forced to drop out of U.A. in order to keep his loved ones safe as All For One and Shigaraki are targeting him to get their hands on One For All.
The flashback of Inko and Izuku playing together when Izuku was a little kid was considered one of the cutest scenes in the manga and in the anime, but it reached new levels of heartwarming when Horikoshi admitted that the scene was inspired by his own time playing with his mom as a little kid and that he cried while making that scene.
Two things from All Might's speech to Midoriya at the start of the series became this after Two Heroes:
All Might made an offhand statement that the man who designed his costumes is his hero. In Two Heroes, it turns out to be David Shield, an old friend of All Might's.
Telling Midoriya to give up on heroism and focus on a job he can do without a Quirk was harsh, but it worked out very well for Melissa.
In a karmic sort of way if you think about it: Aizawa expelled his entire class last year just because they didn't live up to his standards, even if it was only to make a point, and he soon re-enrolled them. He got a little more than he bargained for the next year when his class includes the apprentice of the #1 hero and the son of the #2 hero and, overall, his entire class is quite possibly the strongest U.A.'s ever seen.
All of the comparisons to One-Punch Man became this when Iida's Japanese voice actor, Kaito Ishikawa, provided the voice of Genos in the anime adaptation.
Like any other series out there, My Hero Academia has plenty of gender flip art. Then comes Mitsuki Bakugo, who looks just like a female version of her son. When Horikoshi drew a picture of what he'd thought some of the characters would look like as the opposite gender, Bakugo's genderbend looks almost exactly like his mother as well.
Todoroki's first interaction with Midoriya is stating that I'm Not Here to Make Friends and that he will beat Midoriya on the U.A. Sports Festival. The hilarious part comes from the fact that, by the end of that arc, Midoriya would become his Only Friend and he would also open up to people in Class 1-A and even befriend Yaoyorozu after a while.
With many proclaiming it the "perfect shonen" and praising it as an amazing anime, many come in with high expectations of it. While many are satisfied, others don't see the appeal and consider it another Cliché Storm at worst, So Okay, It's Average at best. Not helping matters is that for many, the start of the series' Growing the Beard is the U.A. Sports Festival Arc, which doesn't occur until Season 2, meaning some drop it before they get to where the anime's praise genuinely comes from.
Character-wise, Tsuyu has been criticized due to how much hype and attention she receives. While not outright disliked, there are those who don't consider her any better than the other side characters.
Thanks to the series winning a large glut of awards during the 2017 and 2018 Crunchyroll Anime Awards, many fans of other series were not amused. It got to the point where detractors accused the awards of rewarding popularity over quality.
Midnight/Mt. Lady is referred to on Tumblr as "M'Lady".
"Mighty Family" for Inko/All Might.
Kaminari/Ashido is known as "Battery Acid".
Bakugo/Kirishima is "Pop Rocks"
Kaminari/Jiro is known as "Lightning Cable/Lightning Jack".
Bakugo/Ashido is "Acid Bomb".
Deku/Uraraka is "Green Tea". Explanation In Japanese, Ochako's name includes the kanji for "Tea" (茶) while the name Midoriya includes the kanji for "Green" (緑)
Informed Wrongness: At the end of the Provisional Hero License Exam Arc, Todoroki is one of three major characters to fail to pass the exam, the other ones being Bakugo and Yoarashi, with the reason being that his I Work Alone attitude and him getting into an argument with Yoarashi that almost resulted in Unfriendly Fire towards another student. However, Todoroki comes across as less deserving of the criticism compared to Bakugo and Yoarashi, who failed for similar reasons. To begin with, Todoroki worked alone specifically because his powers could risk unfriendly fire if he used them in a careless manner, so it isn't like he's running off like Bakugo did, as Todoroki was trying to be as safe as he could. In the case of his argument with Yoarashi, it wasn't like Todoroki instigated it, as Yoarashi continually was harassing him for petty reasons, and was getting in Todoroki's way by using his wind Quirk when Todoroki was using his fire Quirk. Really the worst thing Todoroki did was respond and get distracted, which while his fault, was only because Yoarashi was instigating it. The fact the instructors said the intent of the exam was to get heroes to work together also comes across as biased on their part towards people who have powerful but hard to control Quirks like Todoroki's.
Despite the series having a gauntlet of villains who range from mass murderers to Omnicidal Maniacs, Endeavor is particularly despised by a significant portion of the fandom for what he did to his family. He put his five-year-old son Shoto through such hellish training that the boy was left vomiting and crying on the floor. And he mistreated his wife to the point where she snapped and scarred her son by pouring boiling water on his face. These fans reject Endeavor's Character Development and hope Dabi, a known mass murderer who has since been revealed to actually be his thought deceased son Toya himself, slowly and painfully burns him to death.
Despite being one of the heroes, Mineta is more reviled by the fandom than any of the villains. He's a shameless pervert who constantly makes unwanted advances on his female classmates — harassing them, spying on them, groping them, and so on. At one point, he even goes so far as to make a pass at a traumatized six-year-old. Despite not being a villain, Mineta's slimy, lecherous demeanor makes him come off as a more realistic individual to hate.
Bakugo has a small but vocal hatedom for his treatment of Midoriya early on in the series, which involves bullying him, blowing up his belongings in broad daylight, and suicide baiting him in the very first chapter. As a result, numerous popular fanfics have author bents that vilify or otherwise brutally punish him under the belief that he's a Karma Houdini even after his Character Development from a Jerkass into a Jerk with a Heart of Gold. Some writers even have his quirk stolen by All For One, resulting in some cheers despite the latter's reputation as a Card-Carrying Villain who murders For the Evulz.
Unsurprisingly, there's a good amount of Bara fans that like the manga, since every male character is built like a brick wall with Midoriya, Bakugo, Iida, Kirishima, and All Might being among the favorites. Endeavor deserves special mention for being the subject of most bara fanart of the series and have become somewhat of a Bara icon for artists.
Trans fans have really shown approval of Tiger, a trans man and member of the Wild Wild Pussycats. Magne being a trans woman was also well received, especially in regards to how her voice actor is supportive of her and Twice angrily calling Overhaul out for using the wrong pronoun for her.
There are a good portion of fans from the LGBT community that interpret that characters such as Kirishima and Jiro are actually gay, with some fans believing and cheering for them to come out, as a result, both have gotten a considerable following of gay fans.
In a non-villainous example and rather odd case, Minoru Mineta has actually become this for a section of the fanbase. Although he's pretty much The Scrappy for the entire series for being a complete pervert and wimp with almost no other personality traits, some fans don't actually mind keeping him around just so they can hate on him and see him get his well-deserved comeuppance.
Another non-villainous example is Neito Monoma. He's a giant jerk to Class 1-A and is obsessed with proving that Class 1-B is superior, but he's so over-the-top and smug that fans finds him hilarious for it.
Shigaraki, better known as All For One, is an incredibly powerful villain and the Arch-Enemy of the heroic All Might. Secretly ruling the country from the shadows for generations, All For One was seemingly killed by his enemy, but survived and rebuilt a group of villains in secret. Wanting to hurt All Might, All For One tracked down All Might's mentor's long-lost grandson, and raised him as the villain Tomura Shigaraki, knowing this revelation would be the one thing to crush All Might's heroic spirit. Even in his final battle with All Might, All For One is pleased even if he loses, knowing his loss will inspire Tomura to become the greatest villain in history to oppose All Might's own successor.
Dabi, born Toya Todoroki, is one of the most dangerous and crafty members of the League of Villains. A master of psychological warfare who enjoys making his opponents doubt themselves with well-placed words, Dabi later reveals he is only using the League towards his own purpose: the ruination of his father Enji Todoroki, new number one hero Endeavor. Recording a video to expose the abuse he put his family through to the world, Dabi releases it at a moment of incredible crisis to destroy faith in heroes while revealing his true identity to Endeavor and Shoto, aiming to tear down hero society, spread the ideals of his idol Stain and utterly destroy his father.
"Gentle Criminal", real name Danjuro Tobita, wanted nothing more than to be a famous Pro Hero. When he failed in his goal and was abandoned to poverty, he decided to become a villain instead. Gentle Criminal successfully commits thefts and evades the law for six years with the help of his partner La Brava, who he cherishes and supports, never killing anyone in the process. Unable to gain the fame he desires, Gentle devises a brilliant scheme to break into U.A. High for fame. Facing down against the teenage Hero Deku, Gentle gives him a hard battle, creatively combining his otherwise weak power of Elasticity with a keen analytical mind. Upon his apparent defeat, Gentle uses La Brava's powers to restore and enhance himself, giving Deku an even more intense battle. Even upon truly losing, Gentle manifests the last of La Brava's Quirk using sheer willpower and creates a last moment scheme to ensure La Brava avoids punishment, which Deku goes along with out of genuine respect and sympathy toward him, and ultimately goes down a path of redemption, becoming a Hero like he always wanted.
Mirio Togata almost immediately became this after he gave a seriously awesome No-Holds-Barred Beatdown to Overhaul after losing his Quirk. Several fans have stated, jokingly or otherwise, that if Mirio had been the one to receive One For All, then the series would have ended much quicker.
Any character with a very cartoony Nonstandard Character Design is typically turned into this by the fanbase. Wash, for example, has gathered quite a few readers that joke abut them being super powerful, despite their little screen time.note Having a major villain named Stain helped push the joke as well. Slidin' Go has gotten a similar reaction due to his Seth MacFarlane-like design.
Thanks to My Hero Academia: Abridged, Backdraft has become a small source of hype in the fandom despite his very limited screen time.
X-Less, originally an unnamed background hero who participated in the Hideout Raid, had a brief but glorious stint as this after his proper introduction much later in the series. He takes part in the Hospital Raid during the Paranormal Liberation War Arc with several other heroes and ends up in the unenviable position of securing Shigaraki's comatose body, making him an obvious Red Shirt who would be the first killed the moment Shigaraki wakes up. However, several chapters go by without him waking and X-Less quickly gained a reputation in some online communities as the man who refused to stop living despite already being dead. With every chapter his legend grew, to the point that some jokingly speculated that his true quirk was to cheat certain death. Sadly, he is dusted the moment Shigaraki does wake, but his legacy continues to live on after Shigaraki claims his cape for his own and starts wearing it as he begins to cause untold destruction.
No matter how badass he gets, some fans (and haters) will just never forgive Midoriya for being timid and Prone to Tears, portraying him as a paper-skinned crybaby who bursts into floods of tears at the slightest provocation and happily accepts all of Bakugo's abuse without a single word of complaint.
Owing to his Scrappy status, Mineta frequently gets hit with this.
Although he isn't really disliked, a lot of fans will make fun of Ojiro for having a pretty lame Quirk and being a rather "boring" character who doesn't do much in the series.
Tomura Shigaraki initially started off as this with many joking about him being a "villain wannabe" or that he's trying too hard to be evil. His rather odd-looking character design was also the source of many jokes. However, this later diminished when he seriously Took a Level in Badass and became a much more threatening and competent villain.
Spinner, who has a useless Quirk and tries to imitate Stain so much that he even dresses like him. The fact that he looks like a Teenage Mutant Ninja Turtle doesn't help.
Mustard, for having a Weaksauce Weakness (he isn't even immune to his own quirk) and being taken out rather easily while not contributing much to the story.
A few fans actually think of Overhaul as this, since his whole villainous operation was shut down fairly quick and he rather idiotically thought the League of Villains would just bow down to him after he killed one of their members, making him look somewhat incompetent as a result.
Mineta is a sexual harassment suit waiting to happen. He barely even requires the "memetic" qualifier, given that he spouts inappropriate comments about women practically every time he opens his mouth.
Most of the Villain!Midoriya ships have shades of this, especially if it is with other villains.
Shinso/Midoriya gets this quite a bit, particularly due to how Shinso's power basically allows him to force others to do whatever he wants and Midoriya being naïve enough to never avoid an opportunity for Shinso to use it on him.
Stain seems to be a parody of this, as he's an in-universe example of Evil Is Cool (as Kaminari once said and merchandise of him being sold), Draco in Leather Pants (Toga being his fangirl), and Villain Has a Point (Midoriya saying that he had understandable goals).
Some fans seem to think that Midoriya uses the hero name Deku because of Bakugo, when actually, he states in the manga to use the name because Uraraka changed the meaning of it for him ("Deku" can be read both as "Useless", which was what Bakugo meant by it, and "Never give up", which is what Uraraka means by it). Deku was a name Midoriya was embarrassed of because it was a way for Bakugo to bully him, he gladly accepted the name after Uraraka started using it more respectfully.
Some of Rei Todoroki's Ron the Death Eater status came from the fact that people accuse her of being a mentally unstable person to become a mom, completely ignoring that her worst moment in her mental health came as direct result of the abuse she suffered at her husband's hands.
Some fans love to portray Dabi as a loving older brother to Natsuo, Fuyumi and Shoto, who team up to play pranks on Endeavor. This is completely ignoring the fact that Dabi, even when he was still a kid (known then as Toya Todoroki), hated Shoto from day one, seeing him as his more successful replacement and while he did have some love for Natsuo in his childhood, as an adult, he is more than willing to murder him in cold blood too if it means it'll cause Endeavor grief. In fact, in the canonical manga, the Todoroki siblings, and matriarch decide to work with Endeavor to stop Dabi, instead of the other way around.
Mis-blamed: In the anime, the last parts of Mirio's fight against Overhaul are shown via a slideshow with very little movement. This led to some criticism that the anime was skimping out on the animation during a very important scene, including some accusations that My Hero Academia: Heroes Rising was eating into the budget. However, the manga also used only a handful of text-only panels for this scene, meaning that the anime actually showed the fight in even more detail than what would have been necessary.
A very hearty number of fans have also fallen in love with Eri. Opinions range from sweet little girl to downright adorable and precious. This is especially apparent after the Cultural Festival, and how her true personality has shined through ever since.
Shigaraki crossed the horizon during the USJ Arc when he tried to kill the U.A. students in an attempt to lure All Might out.
Stain crosses it in his introduction when he attacks Tensei Iida and permanently cripples him. Despite Stain's claims that he only went after heroes that don't adhere to All Might's ideals, several scenes reveal that Tensei was a Nice Guy.
Muscular already crossed it when he beat the hero team Water Hose, Kota's parents, to death for fun. And Muscular wants to do that to everybody he beats up, including their young son Kota. It's also implied that the villain tortured Water Hose before he killed them For the Evulz.
All For One crossed it when he killed Nana Shimura, All Might's predecessor, and then took her grandson to train him to be his successor.
Overhaul's horrifying treatment of Eri cements him as true evil: in order to produce his Quirk erasing bullets, he repeatedly used his Quirk to disintegrate her, extract her blood, then reassemble her, a process which is described as extremely painful and left Eri traumatized. There's also him destroying Mirio's Quirk and murdering Sir Nighteye.
Skeptic of the Meta Liberation Army's attempt to "recruit" Twice, by using his puppet-making Quirk to psychologically torture him over his severe issues from an incident where his own doubling powers went horribly wrong. His attempt comes down to creating puppets that look like Twice, having some of them hold him down and have others try to kill Toga in front of him, and breaking Twice's arms when he tries to stop them.
Trying to murder his baby brother and killing over thirty innocent people in cold blood is bad enough but Dabi officially crosses it when he reveals Endeavors history of abuse to the public, damaging Hero Society and frames Hawks as having murdered Twice for no reason, completely disrespecting his fallen allys memory.
Some of the hero names the students chose. Imagine being saved by a hero named "Grape Juice" or "Cellophane".
In episode 33 of the anime, Todoroki has a brief flashback to episode 31, when he, Midoriya, and Iida were visited by the police chief, who is an anthropomorphic dog. The problem is that this flashback is not accompanied by any dialogue, so if you didn't see episode 31, it appears to just be a still image of a dog wearing a suit that pops up for no reason◊. Even knowing the context, this scene can still be funny just for how sudden, silent, and short the flashback is.
The scene where Midoriya learns about the circumstances behind Kota becoming an orphan can lose a bit of its emotional punch given the fact that Midoriya's dressed in nothing but the Modesty Towel he'd been wearing at the hot spring, while Mandalay and Pixie-Bob are both fully-clothed.
Moonfish can be this. His design and concept are so over-the-top creepy that he's either one of the scariest villains in the series or impossible to take seriously.
All Might screaming a Big "NO!", in English, after failing to rescue Bakugo from Shigaraki's bar. However, for obvious reasons, this isn't really a problem in the dub.
The revelation that Yoarashi harbors a serious grudge with Todoroki because he and Endeavor were each rude to him once. That prompted him to move another school halfway across the country to get away from him and drives him to pick a fight in the middle of their provisional hero license exam.
Eri trying to smile, and then saying that she doesn't know how to during Mirio and Midoriya's visit in the hospital. It's supposed to be a tragic scene to highlight the lasting effects of her trauma, but it's so over the top melodramatic that it's hard to take seriously.
In the English dub, Ending can be a bit harder to take seriously since he talks in such a high-pitched and over-the-top manner even for an insane convict.
The Finnish translation ends up feeling like a different story at times, far more lighthearted and often dissonant, as a result of a single translation choice: on account of a dearth of good-sounding equivalents for "villain", they were forced to go with "pahis", which would at best mean "bad guy", and at worst "baddie". Now imagine the serious and collected Kurogiri calmly introduce the villains as "We are the Baddie League. We are here to kill All Might", and you will see the extent of the problem.
Shigaraki's design. In any other situation, a villain with a severed hand over his face would be pretty unintentionally hilarious. However, Shigaraki's design manages to make it look creepy, and the fact that the hands came from Shigaraki's dead family also helps.
Endeavor constantly being on fire may look a little ridiculous, but many fans love it because it makes his design stand out and actually fits his character. It helps that it's implied he does this to look vigilant and intimidating as a hero in public, as when he's home the fire is mostly nowhere to be seen.
All Might's finishing blow attack announcements, usually "[random American state] Smash!", are pretty ridiculous, but they're delivered with such seriousness, and in such climactic moments, that, at least after the first couple of times, it's hard not to like them. Especially once Midoriya starts imitating them, and in the especially dramatic case of All Might's final One For All powered punch, "United States of Smash," used to take down All For One. More goofy Gratuitous English, but it also makes perfect sense as the culmination of everything he's fought for, bringing together the strength of all his predecessors and supporters.
Midoriya fighting Gentle so that the U.A. Cultural Festival won't get shut down would seem like it's narm because it sounds like Skewed Priorities, but it reaches this when you remember it's because he wanted to let Eri have fun after the hell she went through. It also comes after several arcs of the class struggling to survive and progress in their education, making it one of the few moments of an In-Universebreather arc that would justify his drive to ensure the class succeeds.
Nausea Fuel: Seiji Shishikura's Meatball Quirk, as seen in Chapters 106 and 107. Lovecraftian Superpower doesn't even begin to describe it. It transforms the victim into an immobile, yet still conscious lump of flesh.
Mineta's perverted antics have crossed so far over the line at times that a good amount of fans find his actions to be completely unforgivable, even if he's done something heroic since then. His declaration of Jail Bait Wait to a six-year-old was the last straw for a lot of people.
Todoroki's mistaken belief that Midoriya is All Might's secret love child was never let go. Fancomics and fan art have Todoroki comment◊ about it constantly whenever Midoriya and All Might are together even though it's never brought up again in the manga. It sometimes gets extrapolated into Todoroki believing that Mirio is also All Might's secret love child and that Shinso is Aizawa's illegitimate son.
The first thing mentioned about Rei Todoroki is the fact that she was the one who caused Shoto's scar by pouring boiling water on his face. While this happened during a moment of temporary insanity caused by the stress of being in an abusive relationship with Endeavor, Shoto quickly forgave her, and it's later revealed that she had tried to protect Shoto from Endeavor, and later helped give him the epiphany that he doesn't have to be like his father (remembering this helps Shoto use his fire against Midoriya), some fans have never forgiven her for this.
Midoriya is better known outside the fandom, and even by some inside of the fandom, as "the protagonist that cries a lot". While he did start the series crying often comically, by around the Internship Arc he had mostly dropped that habit outside of situations in which anybody would cry like the death of one of his mentors or a heartfelt conversation with his mother and these are sometimes gags. Calling him a bad protagonist because he cries a lot has since started to become a Fandom-Enraging Misconception.
Endeavor's abuse towards his children, notably Shoto, makes it hard for some fans to forgive him for what he did.
No matter how you view Death Arms as a character he'll always be remembered as the guy that yelled at Deku for trying to save Bakugo from the Sludge Villain.
A small but notable portion of fans still holds Tsuyu's claim that breaking the rules to go rescue Bakugo would make Kirishima and the others no better than villains against her. This is despite the fact that Tsuyu soon apologized for saying this, and Aizawa considered Tsuyu as much of an Accomplice by Inaction to the unauthorized rescue attempt as everyone else besides Jiro, Hagakure and Bakugo.
The first villain Midoriya and Bakugo encounter has rather uncomfortable subtext with them. It comes from being a slime villain with a habit of trying to take teenage boys' bodies.
Toga has intense Foe Yay with anyone she fights against, particularly Midoriya, Tsuyu and Uraraka, all of whom she appears to be crushing on. However, she has full intention of murdering everyone she got a crush on, even Stain, take their blood and ultimately, take over their life by using her Quirk to take their appearance.
Some people think that Shigaraki and Stain's interest, bordering on obsession in Shigaraki's case, towards Midoriya has strong undertones of this.
Mineta with anybody is seen as this, likely owing to his Scrappy status.
The Winged Nomu from the Hosu attack, due to the implications that he might be one of Midoriya's companions from childhood. Horikoshi provided a "hint" image of the boy in question in the manga volume.
Mitsuki Bakugo only shows up for one scene in the aftermath of the Hideout Raid Arc (apart from yelling at Bakugo off-panel after the U.A. Sports Festival Arc), but has gained memetic infamy as Katsuki's surprisingly hot mom. It probably helps that she looks exactly like Katsuki as a woman.
Snatch is a pro hero who briefly shows up at the end of the Internship Arc, when the League of Villains attacks the convoy transporting the arrested Overhaul. He manages to give Shigaraki a surprisingly tough fight due to having a Quirk that's a good counter for Shigaraki's. He even gives an Armor-Piercing Question to Dabi before the latter kills him with Mr. Compress's help.
One nameless hero who shows up in the Paranormal Liberation War Arc catches Mr. Compress and Toga in his Quirk, all while delivering a short but effective statement of how the villains' troubled pasts don't justify their crimes. He's only thwarted by Twice's final clone stabbing him in the head.
Cassie Bate, codename Star and Stripe, shows up for a single (admittedly multi-chapter) fight with All For One in Tomura's body and absolutely owns in said fight, posing a massive threat to the Symbol of Fear himself, displaying a ridiculously powerful Quirk that could rewrite reality to a limited extent, nearly scoring a highly improbable win, and ultimately performing a Heroic Sacrifice by rewriting her own Quirk to sabotage All For One, doing what seemed impossible and driving the seemingly unflappable villain to panic. Despite having only one scene to her name, a fight scene at that, Star made quite the splash.
Due to Midoriya being the Launcher of a Thousand Ships and a Gotta Ship 'Em All situation in the fandom, you can basically pick two characters and throw them on Midoriya and it would work. The most popular are Todoroki/Midoriya/Bakugo, Iida/Midoriya/Todoroki, Uraraka/Midoriya/Tsuyu, and Iida/Midoriya/Uraraka. Bakugo/Midoriya/Kirishima and Bakugo/Midoriya/Uraraka became popular soon after. To a less popular degree, Kaminari/Midoriya/Kirishima and Yaoyorozu/Midoriya/Todoroki also exist.
Dabi/Shigaraki/Toga is not unheard of. Specially since they are three of the most popular villains and their introduction shows some tensions between the three of them.
Kaminari/Kirishima/Bakugo has a surprising amount of fans, both due to Kirishima/Bakugo already large fanbase and Kaminari's popularity and proximity to the both of them.
Todoroki/Yaoyorozu/Jiro is another surprisingly popular ship, due in part to the popularity of both Todoroki/Yaoyorozu and Jiro/Yaoyorozu and as a means to combine them so as to solve shipping issues.
Mirio/Tamaki/Nejire has sparked in some circles. They are shown to be really close friends, Mirio and Nejire have served a bit of fanservice and the trio's general popularity as characters.
Among the adult characters All Might/Aizawa/Present Mic has a certain following.
There's also Aizawa/Midnight/Present Mic, since the three are friends and Midnight is the one that recommended Aizawa become a teacher in the first place.
Above the value of three, there are OT4s and so on. Midoriya/Bakugo/Todoroki/Shinso, Midoriya/Bakugo/Kaminari/Kirishima, Midoriya/Todoroki/Iida/Uraraka, etc.
Mirko/Endeavor/Hawks got popular as a source of lewd fanart and fanfics.
Paranoia Fuel: Toga. She is capable of taking the place of anyone she takes the blood from. She was able to pose as Camie for a few days, meaning she was around the latter's friends and family without no one realizing the real Camie was somewhere, with god knows what was happening to her during this time period. Even worse, Toga can now turn into Uraraka and Midoriya, two people she made sure to know they were trusted and loved by their peers before taking their blood, therefore, she is now capable of infiltrating Class 1-A. During the Meta Liberation Army Arc, she got a power-up allowing her to replicate the Quirk of whoever she impersonates, which transformed her from a medium threat in the League to one of its strongest members.
Periphery Demographic: Women felt really attracted to the manga, due to its highly respectful portrayal of women for shonen manga standards. Not only are all girls of Class 1-A confirmedly badasses, but none of them ever get the Faux Action Girl treatment or gets reduced to a source of fanservice. Yaoyorozu, the resident Ms. Fanservice, not only has the fanservice justified, but also is a fully fleshed out character, even getting Character Focus on her self-worth issues during the Final Exams Arc. The other source of fanservice, Mt. Lady and Midnight, both have it fairly downplayed or even Played for Laughs, such as Mt. Lady using her sex appeal in order to get free food. Another point that women love about the manga is that the bodies are realistic and don't have the absurd waist-to-chest ratio that puts most women off in other manga. For those that don't mind a bit of manservice, it helps that a lot of the male heroes have that classic superhero definition built into their suits (or lack thereof in some cases).
Popular with Furries: The series is quite popular with furry fans due to characters such as Tsuyu, Tokoyami, Selkie, and Gang Orca, whose Quirks give them animal-like traits or make them outright anthropomorphic animals.
Rescued from the Scrappy Heap: The Character Development Bakugo undergoes throughout the Paranormal Liberation War Arc managed to drastically improve his standing with readers who were formerly his staunch detractors: he acknowledges that the reason he harassed and bullied Midoriya was because of his own insecurities, and he later ends up Taking the Bullet for him. The first thing he has to ask when waking up afterwards is if Midoriya is okay. He proceeded to get even more of this when he finally apologized to Midoriya about bullying him and admitted he was wrong about almost everything ever since he got into U.A.
Mineta. Since a lot of fans hate him he often gets portrayed as even more unlikable, idiotic, incompetent and perverted than what he actually is. He is indeed one of the characters from Class 1-A that needs the most Character Development and training, but fanworks tend to make him a lost cause. Fanfics with Ho Yay pairings have gone as far as to portray him as a homophobe. Some works also portray him as a transphobe, and some even combine the two. (However, there is a fic where he responds to Bakugo's coming out as a girl with a joyous proclamation of "Yes! Another set of boobs in the world!")
Hisashi Midoriya, Izuku's father, is frequently portrayed as being as abusive and neglectful as Endeavor if not an outright villain despite not having a single onscreen appearance, usually as part of a Die for Our Ship to push All Might or Aizawa towards Inko.
Bakugo gets this, to a certain degree, given how cruel he was earlier in the series, but sometimes his cruelty is overamplified, despite the character development he has been put through as the manga progressed and his haters tend to pretend he has no redeeming qualities.
On the flipside, some fans who want Bakugo to look better than he was will try to demonize Deku somehow, a common one being to portray him as an annoying or even creepy Stalker Without a Crush, justifying Bakugo's actions by saying he wouldn't have had to bully Deku if the latter just left him alone—barring the obviously disturbing implications there, this also undermines the aforementioned character development on Bakugo's part by presenting him as blameless and sympathetic from the start and not as a flawed person who needed to learn to be better.
Bakugo's parents, Mitsuki and Masaru, are sometimes portrayed as abusive to Endeavor's degree, with Mitsuki being actively abusive and Masaru being a Useless Bystander Parent. This is due to some fans not taking lightly how Mitsuki has taken to physically disciplining her son after his kidnapping. Some of Bakugo's fans also believe that it is this supposed abuse that made Bakugo such an angered and hateful person to begin with (e.g. when he proposes forcing the Masegaki kids into submission, he remarks that was how he was raised), even though the manga went to lengths to explain that it had nothing to do with his parents, aside from the fact that they failed to notice their kid was becoming aJerkass.
Monoma is a Jerkass in-universe, but many fan works take this Up to Eleven, making him more cruel than he actually is. In some cases, hes simply portrayed as a one-dimensional Butt-Monkey, but other works go as far as to turn him into a Complete Monster, having him do extreme things like mocking people for mourning another persons death. His Hidden Depths are rarely shown, and most of the time, he is portrayed as the villain of the story, bullying either Midoriya or Bakugo or anyone in Class 1-A without an ounce of sympathy.
Even Inko isn't safe from this trope, despite being a loving mother and a complete sweetheart. It doesn't seem to be out of dislike for her character personally, but some fanfics will turn her into an abusive parent to make Izuku's life more depressing for whatever reason.
The Meta Liberation Army are villains in canon primary defined by the idea of using their powers without legal restriction, but in fanfics they have quickly become a go-to group for Quirkless discrimination and mistreatment. On top of this aspect of canon being greatly amplified by fanfics than what canon ever showed, this entire concept applies to the Meta Liberation Army entire from one line by Geten about society being measured by the strength of one's Meta ability, taking a one off line from a non-leader of the group and making the entire organization and linked groups hostile to the Quirkless in everything from being a hero to basic human rights.
Gentle and La Brava became such likable villains, there was a fraction of fans hoping they would win the battle against Midoriya, or thought that he was being an asshole for not letting them get away scot-free. After the fight, Midoriya does have enough sympathy for the two to downplay the fight as much as possible, and the aftermath of the arc seems to imply they'll both get off very lightly.
While not villains, Class 1-B are something of a Friendly RivalryOpposing Sports Team and anytime they a pitted against Class 1-A, you can find more then a few fans hoping to see Class 1-B come out on top. This is helped by Class 1-B seeming more like the underdog in face-offs compared to the heavily praised and battle tested Class 1-A.
Everything the League of Villains has done since All For One's arrest counts as this. They're regularly losing members to the law and other villains, basically public enemy number one, and only seem to have each other, yet there's something just extremely compelling about seeing them struggle against these odds, take these licks, and survive. In their focus arc, they're pitted against the Well-Intentioned Extremist liberation front, slaughtering them in droves, and one can't help but cheer for them all the way as they try to rescue their captured Giran. Shigaraki, especially, people are really looking forward to the much foreshadowed day he finally truly succeeds his master.
Anyone going up against Endeavor was bound to get this from his detractors, but suffice it to say many fans wanted to see Dabi turn Endeavor to ash during the Paranormal Liberation War, seeing him as the logical consequence for Endeavor's abusive actions. This is likely why Dabi's Revenge by Proxy goal is so heavily emphasized even fans who don't like Endeavor aren't likely to support the murder of Endeavor's children for deeds they had no part in. That doesn't stop many fans from hoping he takes Endeavor out along the way.
The Scrappy: Mineta has a sizable hatedom and tends to rank low on popularity polls. This seems to be attributed to his perverted antics, which to a lot of fans comes across as annoying and/or gross rather than funny, and his arrogant attitude and looking down on others (like Todoroki or Bakugo) despite bringing nothing substantial to anything himself. There's also the fact that his character is painfully underdeveloped compared to others, yet, Horikoshi confessed that he is one of his favorite characters, due to being easy and fun to draw, so he tends to get a lot of screentime and page-time compared to other "side characters" in the class. It doesn't help that he's had virtually zero plot relevance at all since his introduction and has very little character development or exploration in the class. Many fans desperately wish for him to leave Class 1-A, usually to be replaced by Shinso (which often happens in Fix Fics).
The fourth season right off the bat primarily adapts the Internship and U.A. Cultural Festival Arcs, two of the most polarizing arcs from the manga. The Internship Arc in particular seemingly suffered from some budget constraints with the long-awaited Mirio vs. Overhaul fight getting lambasted by fans for not being fully animated.
The fifth season amplified these complaints with the animation being accused of being weaker. The decision in Season 5 to change the order of the Meta Liberation Army and Endeavor Intern Arcs lit up a new firestorm and revived these complaints. Complaints intensified when the Meta Liberation Army Arc had several scenes either censored or Adapted Out. The fact that the third movie got a So Okay, It's Average reaction on top of that, it had fans resenting the fact that this season was seemingly treated as an afterthought for the sake of the movie.
Midoriya's body is up to interpretation depending on who is making the fanwork. He looks skinnier in typical Eastern yaoi, but can also look even more muscular than normal if he is intended to look more like a top in a Ho Yay pairing. In the typical Western fandom, there's a considerable amount of care in making him look both lean and muscular. Similarly, the fandom also tends to believe he has freckles all over his body, even though he had a Shirtless Scene early on in the manga that proves his freckles are only on his face. In addition, the Bara fandom often speculates whether or not Midoriya is going to be able to hulk out like All Might does when he activates One For All, leading to fan art of him being absolutely shredded and bulky as a more experienced hero. In the Western fandom, there's a lot of fans who like to portray Midoriya as having sun-kissed, or at least naturally tanned skin. A later trend after Midoriya started focusing on kicks was that He's Got Legs and either has or will get thick, muscular thighs.
Yaoyorozu's hero costume get a lot of fan redesigns as a segment of her fanbase, mostly her non-Japanese fans, doesn't feel that her actual outfit is age and/or character appropriate. Her fan designed outfits tend to cover her up more or provide as much coverage as her actual outfit but in a way that are less sexualized. Some fans contribute outfits that are even more revealing, and thus more practical for her powerset, but which reveal skin in a less sexualized manner. Many of these designs amount to a stylized sports bra with shorts, or a sports bra with her existing skirt design, which was actually how her original design, as shown by Horikoshi's early concept sketches, would look like.
Uraraka is often shown as chubbier than what she actually is.note It should be noted that this has some justification in-canon. In an interview, Horikoshi mentioned that Uraraka is plump◊ but only by Japanese standards, which is a size that usually falls in with normal body weight to Western viewers, who are the ones who usually draw her as being more heavy-built.
Shigaraki is subjected to this, especially after the Shigaraki/Dabi ship started attracting fans. He has a lot of marks on his face, from his cracked lips to his wrinkly eyebags which give him the appearance of a shut-in who doesn't get a lot of sleep, and a disturbing smile which is overall far from a pleasant sight. His deformities are often toned down to dark circles around his eyes, some random marks, and scratched lips, keeping a kind of dark alternative to the Bishōnen style.
Tsuyu is often drawn to be more human-looking in fan art with sometimes her figure getting a bit more emphasis.
While Aizawa doesn't look bad by any means, fan art tends to clean him up to make him look less of a groggy mess and more put together.
Hatsume gets this sometimes, mainly wearing more flattering/less clothes and her face being drawn in a more standard style.
There is a large group of shippers and even fans who don't ship any couple at all that dislike and often openly attack Bakugo/Midoriya. The groups accuse fanworks of that ship of Romanticized Abuse since it depicts a victim falling in love with his bully and the fans have the general belief that there is no possible healthy outcome for a romantic involvement between Midoriya and Bakugo. Some shippers are particularly fond of giving Bakugo the Ron the Death Eater treatment in their works. These shippers in particular point out how difficult their current relationship is and how hard would it be to create something healthy out of it. Midoriya/Bakugo shippers, on their part, defend the ship by claiming Bakugo has indeed improved and that it seems that their relationship has improved as well, also stating that Bakugo/Midoriya revolves around Character Development, on both sides. Many often try to work the issue in their fan works, use and abuse of Alternate Character Interpretation to explain the character's actions and often just create and entire Alternate Universe Fic to create a romance in a situation where the bullying never existed.
Another popular ship that rivals the hatedom of the Bakugo/Midoriya ship is Bakugo/Uraraka. Disliked by Bakugo/Kirishima shippers, Midoriya/Uraraka shippers, and the above mentioned Bakugo/Midoriya shippers alike, many have claimed that Uraraka dislikes, if not outright hates Bakugo, and it seems to be the same on Bakugo's part. Also, Bakugo and Uraraka haven't had a major moment between each other since their Sports Festival fight, if zero at all, which was also the first time onscreen they've encountered face-to-face, and it wasn't even by choice; the fights were selected at random. Fans of the ship says that during their fight, which seems to be the only source defense for defenders of Bakugo/Uraraka shippers, Bakugo sees something in Uraraka, that she isn't a frail schoolgirl and he acknowledged her determination. While the shipping has somewhat died down, the only popular ship that doesn't outright attack them is Midoriya/Todoroki, causing them to be Ship Mates.
Hawks/Endavor vs. Hawks/Dabi shippers. The latter thinks that the former are forgiving Endeavor too easy and shipping Hawks with an certified Domestic Abuser (and Endeavor being in his late forties while Hawks is the same age as his second eldest child), while the former point out that the latter are shipping Hawks with a certified Serial Killer and Hero Killer and accuse them of hypocrisy for it, claiming neither ship is perfectly functional, but at least in canon Hawks hates Dabi and likes Endeavor and between the two, Endeavor hasn't tried to and nearly succeed in murdering Hawks unlike Dabi.
Shipping Goggles: Shipping runs wild in the fandom, even though the manga itself is pretty much No Hugging, No Kissing, so otherwise friendly interactions are interpreted as possible romance.
The rise of popularity to Bakugo post-Character Development caused him to be shipped with several characters, many of which he has little to no interactions with, Bakugo/Tsuyu and Bakugo/Toga being the most prominent among them, especially for the fact these characters rarely, if ever, appeared even in the same page on the comic, let alone having had any relevant interactions.
Midoriya's great status as a Launcher of a Thousand Ships causes him to be very much prone to take part in these. Being the protagonist, he gets the bulk of being shipped with the resident Ms. Fanservices Midnight and Mt. Lady in erotic works. While he showed interest in them, with him commenting on the latter's sexiness, it was entirely out of curiosity for their hero status and he has little interactions with either.
Midoriya/Ashido which gathered a following in Reddit, in spite of the fact they had about two conversations in the manga. This might be because they both share similar heroic ideals.
Midoriya/Dabi is a particularly rare case in which not only have neither of those characters ever interacted with each other prior to Chapter 293, but Female Midoriya/Dabi is more popular than regular male Midoriya among shippers.
Despite not having appeared together yet, being aquatic mammal themed heroes, Selkie and Gang Orca are shipped sometimes.
Kaminari/Shinso can be seen as this. Having a following on Tumblr and Instagram, this ship was given birth during the Joint Training Arc, despite Kaminari only talking to him to befriend him twice, never mind the fact that Kaminari is canonically heterosexual. It can also be a case of Pair the Spares by Yaoyorouzu/Jiro shippers.
Doubling with Toy Ship, Eri/Kota, who have never met, are shipped due to them being in the same age group and their admiration of Midoriya.
Bakugo/Yaoyorozu have rarely interacted, but they have a noticeable, if small, fandom with considerable amounts of fanart. Some people like the idea of a Bad Boy/Ojou ship. To the ship's credit, their interaction in Smash!! was laced with Ship Tease when Bakugo held Yaoyorozu hostage and under the effects of a Bishōnen Quirk, hits on her. And they were drawn in an outfit swap together.
The Forest Training Camp Arc has moments of these. The villains sent to deal with U.A.'s students manage to do more damage than the League of Villains before, and Chapter 75 ends with Midoriya using One For All at 1,000,000% on a villain.
The Hideout Raid Arc where All For One finally takes matters into his own hands. And when All For One moves, that means All Might himself gets personally involved as well. The results? Half an entire city gets itself wiped out from their clash alone. Note that both of them are severely weakened from their last fight, which really begs the question of just what the hell was their last fight like. If that's not all, All Might even goes way past his time limit (which reveals his true form for the whole world to see as well) and just keeps going by using One For All on his arms only. Between all of that, Nana Shimura, All Might's predecessor, is also revealed to be Shigaraki's grandmother.
Chapter 125, where we get our first look at Overhaul's power. Poor Magne.
The battle against Overhaul includes mind-blowing twists, such as Mirio losing his Quirk, Midoriya breaking through the wall to enter the fight and activating Full Cowl 20%, Team Ryukyu falling through the roof to barge in the fight with the last one of the Eight Bullets, Eri's power being awakened and being able to return things to a previous state, with her and Midoriya's powers combined they are able to use Full Cowl 100%.
The Paranormal Liberation War Arc includes many of these moments, such as the deaths of multiple named pro heroes, Dabi revealing himself as Toya Todoroki and revealing Endeavor's abuse of his family to the public, Best Jeanist reappearing after having disappeared for months, Mirio getting his Quirk back and All For One taking control of Shigaraki.
Midoriya using One For All to destroy the Zero Point Robot.
All Might's battle with Nomu at USJ, especially the anime version, which expanded the fight from a mere slugfest into a brawl that sent them crashing all throughout the complex and had "You Say Run" blaring the whole time.
Midoriya and Todoroki's battle in the U.A. Sports Festival with Midoriya finally getting Todoroki to use his fire Quirk.
The finale to the fight between Midoriya and Muscular, particularly the "My Hero" capping it off.
All Might's "United States of Smash!!!" during his fight with All For One, followed by "You're next."
Midoriya, with help from Eri, fighting Overhaul with One For All at its full power.
It's a pretty good manga adaptation of Sky High. Both deal with a world where superhumans are commonplace, with the main character starting off as a Badass Normal who eventually gains superpowers, and taking place in a superhero magnet school that has the world's equivalent to Superman as an alumnus.
It's a softer and brighter manga adaption of the Wild Cards series. Both take place in worlds where the vast majority of the human population possess a superpower with the majority of them worthless (Deuces), some of them turning people into physical mutants (Jokers), a selected few into winners with an actually useful power who can become "heroes" (Aces) and a small percentage of the population without a power altogether (Nats/Quirkless). The only difference between them is the absence of "Black Queens" (aka the mortality rate) in My Hero Academia.
Both are about underdog students with some relation to the resident World's Best Warrior, and their ongoing quest To Be a Master. That said, while Naruto has themes based around The Power of Friendship, and how you don't have to bear your cross by yourself, My Hero Academia is more based around individual success, and having the power to achieve your goals with your own two hands.
The Boys centers around a rogue cell of the CIA whose sole job is to humiliate and quietly murder completely amoral superheroes. The "supes" themselves act less like defenders of justice or protectors of the innocent, and are more like superpowers celebrities who - even the widely beloved Superman Substitute - do nothing but indulge in every hedonistic vice imaginable - including rape and murder - and look good when cameras are around. There are a few Wide-Eyed Idealist heroes every now and then, but their spirits are usually crushed under the sheer hopelessness of the world around them.
In contrast, All Might, the Superman Substitute is a through-and-through Cape and Big Good who has created decades of peace from rogue superhumans and inspired a new generation of young heroes through his sterling example of ideal heroism. There does exist commentary on celebrity-culture like in The Boys (here more comparable to the Japanese "Idol Worship" phenomenon) with the less-than-ideal heroes in the business - ranging from simple divas to fame-obsessed domestic-abusers - but they still are good people who are passionate about their jobs, they have an undeniable positive effect of society, and they help whenever they can because it's literally their job to do so. While The Boys mocked the very idea of superheroes by showing they'd be laughably incompetent in high-stress situations, and never really do anything beyond sell merchandise or host orgies. Meanwhile, the very premise of MHA are superheroes-in-training so that they can properly use their powers in a crisis, and supervillains are a very real daily threat in a world where anyone can be born with dangerous powers, so there will always be a need for protectors. And, rather tellingly, the people who espouse viewpoints that are very similar to those of the titular Boys are the League of Villains or the Hero-Killer.
Consuming a One For All user's DNA in order to inherit their powers. Lets be glad that hair can be used and not say, bodily fluids.
Midoriya constantly destroying his arms and legs is bad enough in the manga, but it takes a whole new level in the anime watching them sickeningly flop around like empty gloves. He didn't just break his bones, he pulverized them. And that gets taken Up to Eleven in the tournament, where he does the "breaking their limbs" things with his wounded fingers over and over again.
The effects of Shigaraki's Quirk on Aizawa's elbow in the USJ Arc. In the manga, it seemed bearable, but compared to the anime, it's much worse.
Mineta saying that he can't wait to meet Eri in ten years. Besides sounding gross, it was beyond inappropriate.
It's been known since the Field Training Arc that the Iida family's engines are Organic Technology, possessing parts such as radiators and exhaust pipes. In the Joint Training Arc, Tenya and Tensei are also seen having mufflers, which the former tears out of his legs so that new ones will grow back in order to make his Quirk stronger. This is roughly equivalent to cutting out a piece of bone in the hopes that you can run faster when it heals. And again: they grow back.
One villain Kirishima fights has a Quirk that lets him spawn blades from his body. That might already be squicky to some people it gets amped up a notch when after the villain boosts his power with the trigger drug he spawns blades through his eyes.
Starboarding: Considering Midoriya's status of Launcher of a Thousand Ships, it's common to make fanfics of several people competing for him, but ultimately, only one of them winning, leaving all the others heartbroken. Particularly, Bakugo is the one most often portrayed as being in love with Midoriya, but due to his bullying, their relationship is forever screwed up. Shinso is another favorite to have feelings for Midoriya that won't be returned, if they are even acknowledged, being a common Romantic Runner-Up in fanfic.
Strawman Has a Point: While the crowd booing Bakugo at the Sports Festival does him and Uraraka a disservice by assuming that he'll perform a brutal No-Holds-Barred Beatdown on her, it's not hard to see where they're coming from, given Bakugo's violent and aggressive nature. It doesn't help that Bakugo ends up winning somewhat easily after he thwarts Uraraka's desperate gambit (proving that Bakugo was at an advantage), or that Midnight later has to sedate him with her powers to prevent him from attacking an unconscious Todoroki.
When the anime was first announced, fans were skeptical since at the time, the manga wasn't even two years old and many thought that it was too soon for an anime adaptation. There were worries that it would overtake the manga and have a lot of filler. However, this was quelled when the anime took a seasonal approach.
Some weren't happy about the announcement of the live-action movie adaptation. And then there's the reveal of a stage play titled The Ultra Stage. They weren't happy due to how other live action adaptations of popular manga/anime series have been poorly received.
Those that still dislike Bakugo due to his horrible Establishing Character Moment consider his humiliating defeat by the Sludge Villain as this; it's even brought up by certain people in-universe who best know him as "that one hero-in-training who got embarrassed by that one villain". His haters also enjoy seeing how he was one of the only two Class 1-A students who failed the provisional hero license exam.
Nearly all of Mineta's perverted antics end with him on the receiving end of some sweet justice:
During the USJ incident, Mineta takes advantage of being rescued by Tsuyu to grope her breasts. She responds by violently dropping him into the boat, instead of putting him down gently like she did to Midoriya. And when he does it again while they are in the water after taking out the villains surrounding them, her response is to hold him underwater.
Mineta notices a peephole in the locker room, which would allow him to spy on the girls while they're changing. It turns out to be a trap set by Jiro, who uses her headphone jack to poke him in the eye.
One particular moment where Mineta gets punished for trying to peep on the girls in the hot springs helped propel Kota to minor Ensemble Dark Horse status. Even better, it turns out that Mandalay had Kota stand guard on the wall because she'd gotten a tip from Aizawa that one of his students was a pervert, meaning that Mineta's reputation is catching up to him.
Kota: Before you become a hero, you should learn how to be a good human. [shoves Mineta off the dividing wall]
During the final fight of the joint training exercise, Mineta comes up with a strategy that has him bounce around using his sticky balls as springboards. He specifically calculated the trajectory so he would also end up bouncing into Ashido's breasts. Not only does she call him out for this, accusing him of being the worst member on the team, she is also later seen subjecting him to the Ludovico Procedure.
Tastes Like Diabetes: After fully recovering from the ordeals of the Internship Arc, much of Eri's appearances can be seen as overly cute now that she can finally live her life as a child. One primary example is in the Endeavor Agency arc, where she participates in her first ever Christmas Party with Class 1-A.
They Changed It, Now It Sucks!: The anime's decision to adapt the Endeavor Agency Arc before the much-hyped Meta Liberation Army Arc caused a big uproar in the fanbase for obvious reasons. While some were okay with the switch, arguing the Meta Liberation Army Arc works better than the Endeavor Agency Arc as a climatic ending to the season and that the switch added a sense of mystery for anime-only fans, many found the switch unnecessary and problematic due to the switch spoiling the ending of the Meta Liberation Army Arc for anime-only fans and breaking the intended pacing the manga set up. Not helping matters is the anime's decision to add in a filler epsiode in the Endeavor Agency Arc to set up the third movie, which itself is often blamed for the switch by detractors.
They Wasted a Perfectly Good Character: Something that Horikoshi laments is the fact he can't explore as much characters as he wants, showing interest in developing and talking more about all of Class 1-A and stating that at least for a while, all he can show is the character profiles. This sentiment becomes more pronounced as the series goes on, as Horikoshi keeps adding characters to his already large cast and doesn't expand them beyond their focus arcs:
The most complained about character in terms of lacking focus is Uraraka, a very notable one since she's supposed to be one of the main characters. She's one of the first fans that Midoriya ever had, is responsible for turning "Deku" from an insult to something Midoriya uses as his hero name, her original goal for becoming a hero is to gain money to support her family, and is one of the first people to get praise from Bakugo of all people (he only says in whisper that he doesn't think she's frail, but since this is Bakugo, that's still noteworthy). You'd expect someone who's done this much to have a larger role in the plot, but she hasn't had any relevance to the story since the sports festival. Whenever discussions are brought up over what characters really need an arc to not fall to the wayside, expect her to be the first one mentioned.
Although Iida did receive a character arc during the Field Training Arc, a lot of fans believe that his character peaked too soon, as he has only received occasional plot relevancy in subsequent arcs.
An interesting variation of this is that some fans feel that Mineta, the resident Scrappy, had potential to be an interesting character due to his unique Quirk, distinct design, and self-esteem issues, and are disappointed that Horikoshi only put more emphasis on his perversion and jerkass behavior, but has yet to expand upon his non-perverted traits. His own character bio says that he's the second smartest person in Class 1-A, but we rarely see any hints of this or why he wants to become a hero in the first place when his two biggest character traits are "pervert" and "coward."
Ashido is one of the more visually striking members of Class 1-A, has a Quirk that is decidedly more villainous than would be expected from a hero in-training (Tokoyami's Quirk is similar, but it's effectively neutral until darkness comes into play) and she and Kirishima are the only members of Class 1-A besides Midoriya and Bakugo who knew each other prior to coming to U.A. Horikoshi has even said he's interested in doing more with her character. And yet, she's one of the very few Class 1-A students to not have had any sort of relevance to the main plot, or even a significant interaction with the main group besides Kirishima.
Nejire, despite being a part of the Big Three, hasn't gotten a backstory, a badass fight, or exploration of her issues and motivations like Mirio and Tamaki did during the Internship Arc, leaving her unexplored, despite being something the fans were very much expecting. This was lightly alleviated in the U.A. Cultural Festival Arc, where she received a sub-plot about her competition on the beauty pageant, though most fans agree that it's too little too late, not to mention it's annoying how the girl of the Big Three gets a beauty pageant instead of cool fight scenes.
A common complaint about the Internship Arc is how the girls never got to do much. While there were several chapters dedicated to the male characters Tamaki, Kirishima, Fat Gum, Rock Lock, Mirio and Sir Nighteye the female characters such as Ryukyu, Tsuyu, Uraraka and especially Nejire all had to share a single chapter and only one fight under the spotlight, a fight in which none of their characters are explored.
The Meta Liberation Army members in the Paranormal Liberation War Arc, with the sole exception of Skeptic. Despite the fact that the arc is about a Villain Team-Up between the two organizations, the League of Villains gets virtually all of the spotlight. Re-Destro, Geten and Trumpet are largely Out of Focus, with only Skeptic getting to do anything important in helping with Dabi's broadcast and being the only one to escape capture. Curious was the only one to be straight-up killed off.
Although Tamaki had a relatively important role during his debut in the Internship Arc, he was noticeably Demoted to Extra afterwards. In the Cultural Festival Arc, he barely has any dialogue and doesn't have any special moments, unlike Mirio taking care of Eri and Nejire participating in the beauty pageant. The same happens in the Paranormal Liberation War Arc, where he has the least screen time and the least participation of the Big Three, with his contribution being limited to a single page in the manga, while Mirio and Nejire were in the center of the main battle fighting against the League of Villains and the Nomus.
More than a few fans have stated they wished that Midoriya had never gained powers and that the series was about him becoming a hero despite his lack of a Quirk. Horikoshi stated that this was indeed the original plan for the manga, but it was scrapped because it would be too unrealistic for him to keep fighting enemies with increasingly outlandish and overpowered Quirks, which All Might explains to him at the beginning of the manga.
The Paranormal Liberation War Arc would have been a potentially good opportunity to show a student dying in the line of duty as a way of underscoring the dangers of hero work. Despite that, while several students are injured and Midnight, a teacher at U.A. is among the dead, all the students make it out of the war alive.
Toy Ship: In response to the Fanon of Eri being rescued after the Internship Arc, Eri is often paired with Kota though they have yet to interact. This is likely due to both being roughly at the same age group.
Often how Todoroki's scars are interpreted, especially since the manga never really draws his scar in a particularly detailed manner.
How some view Tsuyu's mother and Inko, if they don't find them just plain cute.
All Might's extremely emaciated true form has glimpses of this, whenever he puts on a brave smile, or embraces Midoriya.
Shoji has been considered by his fans some sort of ugly sexy. Despite his tentacle motifs, with his tentacles becoming mouths, ears and eyes, he has a quite nice musculature and a very fit body, so some fans think his weird looks actually add up to his charm. These fans are particularly fond of shipping him with Tokoyami.
Koda is surprisingly adorable for someone with a Rock Monster-like face. It helps that he is often surrounded by adorable animals and is clearly stated to have a liking for cute animals, even having a small rabbit in his room and that he is a Shrinking Violet.
John-chan is weirdly as close as a Nomu can get to a Ridiculously Cute Critter. He has odd proportions and an exposed brain, but his big eyes, cutesy name, duck bill, and a pair of tiny sneakers combined with being tiny enough to sit on Ujiko's lap like a cat made a lot of fans declare him oddly endearing. There's also the similarly designed Mocha, which appears to be a Distaff Counterpart to John-chan.
When she's not considered adorable, Tsuyu gets this reaction from some fans.
Any character with a hyper-realistic animal head (like Tsuyu's best friend Habuko) can end up as this, because the style clashes so much with the rest of the art.
At one point, before their rematch, a focus on Bakugo's face shows him with an emotionless, blank and eerily peaceful expression. To someone who is always with either a comical scowl or a creepy angry face, that face can be quite off-putting. The fact he is making that face because he is an emotional turmoil doesn't help.
While it's not an uniform reaction, the poster for the movie showcases a young All Might without Hidden Eyes. While he doesn't look bad, his face not being drawn in the old comic style is offputting to some fans.
Quirks from the body may look that way, like Iida/Ingenium legs being exposed with thrusters on the back or Sero/Cellophane's arms having weirdly shaped elbows shooting out tape.
As shown in Informed Wrongness up above, Todoroki is one of the few people to fail the Provisional License exam due to him wanting to work alone and getting into an argument with Yoarashi that almost resulted in another student being incinerated. However, Todoroki had previously tried to work alone because his powers could possibly hurt other people around him and Yoarashi was continually harassing him for a really petty reason. Although Todoroki eventually got fed up with Yoarashi, it was only because he almost went out of his way to pick on him while in battle, yet the instructors still treat it like it was equally his fault.
How "unintentional" is up to interpretation, but Hawks is shown to be in the wrong for killing Twice, something that civilians call him out on. However, honestly what was he supposed to do? Tragic backstory and mental instability aside, Twice was a literal One-Man Army who could possibly single-handedly kill all enemies of the League of Villains and was completely loyal to them. And due to Twice's powers, it would be rather hard for Hawks to try and take him down non-lethally and he even tried to reason with him (even if it somewhat comes across as Condescending Compassion). As tragic as Twice's death is, it's hard to see Hawks being completely at fault for it.
Unfortunate Implications: Chapter 259 revealed the Doctor's name to be Maruta Shiga, with many people noting that the name "Maruta" was likely a reference to project Maruta, a project done by Unit 731 of the Imperial Japanese Army during World War II that involved inhumane experimentation on various people which included live vivisection, weapon testing, and forced pregnancies. While this name fits Horikoshi's tendency to give his characters punny/meaningful names, the "unfortunate" part comes in when you realize that "Maruta", meaning "logs" in Japanese, was the name given to the test subjects as the official cover story for the facility was that it was a lumber mill. Fans were very upset with the idea of a character as vile as the Doctor being named after the victims of a horrible experiment instead of the perpetrators, especially the ones from Chinanote It even led to the series being taken down online there. and South Korea where the scars are still prominent. Horikoshi later apologized for this on his Twitter account, where he clarified that the reference was unintentional and that he would change the Doctor's name in future chapters.
Part of the reason Bakugo is a Base-Breaking Characteroutside of Japan lies with this. From the moment we first meet him as a child, he's picking on Midoriya simply because he can, and then when he meet him when he's grown up more, he's still a huge jerk who threatens Midoriya and even tells him to commit suicide because Midoriya dared to try and get into U.A. alongside him. From there, Bakugo is an aggressive Jerkass who threatens and yells at people for petty reasons while acting as if the world owes him everything. Thus, whenever the series tries to make him look sympathetic, a number of fans get critical of the writing because he has never earned people's sympathy or trust to warrant being portrayed as sympathetic. It doesn't help that the series keeps trying to push the idea that Midoriya and Bakugo are friends and rivals, when Bakugo has yet to even consider acting better towards Midoriya, the most improvement he has being that he grows to respect Midoriya's power more. Many of Bakugo's detractors often argue that if the story actually addressed Bakugo's bully behavior and used it to develop more, he'd be likable, but point out that Bakugo's character development seems to be just him learning how to make friends.
The entire Todoroki family bar Shoto has gotten their time in this:
How some fans view Rei Todoroki. While there's no excusing what Endeavor did to her, there's also no excusing her taking her frustrations out on her five-year-old son, with some even saying that her action makes her worse than Endeavor. It doesn't help that her taking out said frustrations on Shoto was basically the first thing revealed about her, giving her a hell of an uphill slope to climb into being likeable, despite it later being revealed that she'd tried to protect Shoto from Endeavor. And with her largely divorced from the plot, there's few chances for her to demonstrate her redeeming qualities.
After Endeavor started getting a redemption arc, it was not well received by many fans. At that point, he has been a neglectful parent to most his children and abusive in every level towards Shoto and has nothing but his competence as a hero to have gained a redemption arc. Many feel like Horikoshi expects fans to forgive him easily after an entire arc dedicated to how despicable and awful of a human being he was to his family. The attempt at a heartwarming scene of him stating that he wants to become a hero Shoto can be proud of fell on deaf ears when compared to everything he has done. Many fans went on to state that, if he is not arrested by what he has done, then it's the same as nothing for them.
Fuyumi, in the aftermath of Endeavor's battle against Hood. She tries to get the family together for a conversation and make Natsuo and Shoto interact with him and maybe put the family back together. When Natsuo blows up at Endeavor, calling him out on the fact that he is the cause for the weak bond between siblings, he knows next to nothing about Shoto and mentions a strange event related to Toya, Fuyumi sides with Endeavor and tells Natsuo to calm down, being disappointed at him for leaving. While some fans understand her desire to rebuild her family, some also think that she is glossing over Endeavor's abuse and neglect of her siblings and expect them to forgive Endeavor easily so she can get the family she wants, while disregarding her brothers' feelings. The situation aggravates later when she gives Shoto's contact information to his former abuser without his consent.
The long absent eldest brother, Toya, gets this too. His need to impress his father and show him that he can continue his legacy—a legacy that's been pushed on him ever since he started training— after Enji gives up on him is a legitimately tragic thing, but Toya lashing out at his family for it, up to and including attempting to harm his newborn brother, lost him some sympathy. His stubborn refusal to give up Endeavor's dream when both parents asked him to take alternative paths, coupled with the fact that he became the mass murdering Dabi in adulthood, lost him more sympathizers.
Even Natsuo has gotten his share of detractors. While he has every reason to not want to forgive Endeavor for his failings as a father, some fans saw fault in him because Natsuo specifically got the least amount of negative attention compared to Shoto (who was groomed to be the heir), Toya (who suffered neglect and "died"), and Fuyumi (who tried to protect Natsuo from the worst of it and had to watch the family get broken apart). His tendency to bring up his hatred for Endeavor, especially how it's worded in certain translations, also makes some fans see him as someone holding a childish grudge.
Monoma is an acknowledged case by Horikoshi, who in author notes during the U.A. Sports Festival Arc admits that he meant for Monoma to be antagonistic but not despicable. Since then, he seems to have just run with it, amping up Monoma's negative traits into a Sitcom Arch-Nemesis character for Class 1-A, which ironically made him into an Ensemble Dark Horse for the fandom who sees his exaggerated taunts as quite comical.
The police force in the Field Training Arc. While they are meant to be seen as people just doing their job and keeping the law, fans feel that they are ungrateful for Todoroki, Midoriya and Iida catching the Serial Killer that they have not managed to, and have to leave with none of the glory for their job.
Some fans didn't take kindly to Aizawa scolding Midoriya for using his Quirk against Muscular in the Forest Training Camp Arc. Not only was Midoriya simply protecting Kota at the time, but if Midoriya hadn't gone as far as he did, Muscular would have killed both Midoriya and Kota. This, combined with him threatening to not only expel the five students who went to rescue Bakugo, but also the twelve who didn't report it, can make it seem like Aizawa is less of a tough but fair Reasonable Authority Figure and more like someone who perpetuates rules that keep people's hands tied in dangerous situations.
Bakugo is by far the biggest one. Outside of Kirishima, Uraraka (and Midoriya, to a degree), nobody seems to like him, yet, he's won three popularity polls in a row. This is lessened later in the manga, in which while not many characters seem to particularly like him, nobody pushes him away either, and he manages to live together with others (though it's more because they don't take his anger and brashness seriously than him being civil with them), plus he's starting to show he does care for his classmates, like being angry at the way the rest of the U.A. students are treating them after the League of Villains attacks and agreeing to participate in the band with Jiro.
The League of Villains has many fans, but in-universe they obviously don't, and not even they seem to be quite able to deal with each other without wanting to cut throats at first. They do eventually get closer by the Internship Arc, as Overhaul pissed off the entire group by killing Magne and led to Shigaraki offering to Toga and Twice they avenge her death by sabotaging his plans, but since they are still villains this doesn't help them much here.
Gentle and La Brava are comical villains who consistently see a combination of universal dislike and disinterest from viewers when they attempt to unload their crimes online. Out-of-universe, they're very beloved and are considered to be a breath of fresh air following the Internship Arc.
The way bullying is treated in the manga makes sense to Japanese readers. In Japan, bullying is an issue rarely brought up with teachers and where the bully will rarely face consequences. Although there are initiatives to deal with the issue, it's still a large problem in Japanese schools, with the manga showing that Bakugo really does gets away scot-free with his bullying, but it's shown he faces other consequences because of his bully-like attitude in high school. To Western readers, however, Bakugo seems like too much of a Karma Houdini, exactly because of how subtle the narrative is in punishing him and how they never caused him to question his heinous actions towards Midoriya in the past, with the Western fandom believing that this is a situation where he needs some karmic retribution.
Twice, who is revealed to be 31 in the Volume 24 extras, developing a crush on the teenage Toga would be considered Squick for American readers. This is especially true to a piece of teasing official art featuring him measuring her naked body. While she makes a duckface.
Similar to the age issue above, Yaoyorozu being the main source of Fanservice is a bit of a hot topic of debate among Western fans due to her being still a first-year in high school, while Japanese fans are mostly accepting of it.
Also related to sexuality issues, Mineta's perverted antics are much less warmly received by Western fans, due to a culture where sexual harassment is no longer Played for Laughs. Western viewers tend to view him as less of a harmless nuisance and more of a sex offender in the making who deserves official punishment for his perversion. One thing some viewers find odd is how Aizawa, who's rather strict, hasn't done anything about Mineta's perversion apart from warning him not to try anything.
Viewer Gender Confusion: Magne is a trans woman, but apart from her long hair, she lacks general feminine features. The facial hair doesn't help matters.
Viewer Name Confusion: A good deal of English-speaking viewers seem to think Tenya's last name is Lida instead of Iida because of the uppercase I and lowercase L looking almost identical.
Vocal Minority: Midoriya's haters compose a minority, but a vocal amount of that minority think he's among the worst protagonists ever put to manga, as they believe he is a Vanilla Protagonist (at least, compared to Bakugo and Todoroki) with a boring Character Arc since he's barely changed since the start of the show aside from having better control of his Quirk and crying less.
In the anime, Todoroki is the single target of a huge number of ninja-themed students during the provisional hero license exam. You'd Expect: Them to realize that under the rules, each of them would have to take out two students to pass, and that ganging up on one person isn't worth the effort when only one of them will get the credit. Instead: They focus their energy on taking out Todoroki. The Result: Todoroki manages to get through to the second phase of the exam, but none of his foes do.
In another anime-only part from the same arc, a group of at least seven students pull off an incredibly elaborate and time-consuming plan to trap and subdue Yaoyorozu, Jiro, Shoji, and Tsuyu. You'd Expect: Them to realize that with four targets to capture, only two of them could pass. Furthermore, this method is significantly more time-consuming than the one the ninjas used. The Result: The plan backfires, with the four U.A. students managing to turn the tables on their attackers, and eliminate enough people for all four of them to pass.
Endeavor realized that Toya's flames were hotter than his, but his body was susceptible to heat, meaning he would never be able to put his Quirk to good use as a hero. Both he and Rei try convincing Toya to not hurt himself any more, but he refused to listen, outright obsessed at this point. You'd Expect: Endeavor to realize Toya wouldn't stop this on his own and get him professional help. Instead: He had two more children, hoping Toya would give up his obsession if one of his younger siblings took his place. The Result: Toya not only resented his father, but became jealous enough of Shoto to attack him. He didn't give up on becoming a hero, either, and after his Quirk went out of control and caused him to be badly burned, became the villain known as Dabi and sought revenge on Endeavor.
The usage of the term "Quirk" as a way to refer to the series' superpowers, the equivalent name in Japan is closer to "Individuality", came up from earlier scanlations. It caught on so much that the official Viz release, Funimation dub, and even other scanlators had to follow on it, making the term universal among the Western fandom. The French version went for "Alter", which keeps the meaning, is easy to remember and actually sounds pretty cool.
When All Might sees the fruits of Midoriya's toil on the beach, in the Japanese version, he says "Ohh my goodness!" in Engrish. This is meant to be a comedic moment, but it doesn't come off as such to an English speaking ear. Thus, to preserve the hilarity, and to avoid Lip Lock, it was localized as him saying, "Holy, stinking... SUPER CRAP!"
Tsuyu's insistence on being referred to on a First-Name Basis may fly over some heads due to how it's more formal in Japan to use Last-Name Basis. In the English dub, she asks that she be called "Tsu" as an Affectionate Nickname. While the dub does have most characters on a Last-Name Basis, the insistence on the use of a nickname also covers how "-chan" is an informal and affectionate honorific, compared to how the most acceptable alternative, "Asui-san," is roughly equivalent to "Miss Asui." In the localization of the manga, however, Tsuyu just asks to be called by her first name.
In the Japanese version, the reason why Midoriya goes by Deku is because Uraraka points out that it could mean "never giving up." In the English dub, it was changed to her thinking it sounded like the name of a hero (and that it was cute).
When everybody in Class 1-A selects their hero names, Aoyama and Ashido go right after each other with the names "I Can Not Stop Twinkling" and "Alien Queen", respectively. In Japanese, both of these were considered to be somewhat cringy instances of Gratuitous English, and the class' silent reaction to both was negative. In English, however, "I Can Not Stop Twinkling" sounds utterly idiotic, while "Alien Queen" actually sounds pretty cool, and so for an English speaking audience, seeing both names treated with an equal amount of disdain from the students wasnt going to fly. As such, in the English dub, the moment was turned into a joke about Midnight having hilariously inconsistent taste in hero names, and the class' reaction was changed to flabbergasted incredulity that Midnight accepted Aoyama's hero name with some minor alterations, while Ashido's hero name was rejected.
Bakugo's choices for his hero name are "King Explosion Murder" and "Lord Explosion Murder." Originally, Midnight rejected them without providing a reason as to why. In the English dub, they're rejected because they sound too violent.
When Best Jeanist is giving Bakugo a "The Reason You Suck" Speech about being too aggressive, he uses the metaphor of heroes and villains being "two sides of the same coin". In the English dub, he says that they're "cut from the same cloth", which is the same basic metaphor, but reworded to reflect Best Jeanist's Clothing Combat power.
Class 1-A's Rikido Sato has the Quirk "Sugar Dope", which lets him become stronger byeating sugar. The English translation renames his power "Sugar Rush", which describes the ability much better while also removing the drug reference.
In the scene where Bakugo pays Kirishima back following the Hideout Raid Arc, he has Kaminari go into dimwit mode to distract everybody. However, due to how it's structured, it looks like Bakugo mugged him. The dub throws in an extra line that makes it clear that the money is from Bakugo's own pocket.
When Mineta first met Eri, he made an incredibly squicky Jail Bait Wait comment by saying he couldn't wait to meet her in ten years, which many considered to be low even for him. In the dub, it was changed to him noting that Eri will become a looker in ten years, which is far less creepy.
In a flashback, a young Fuyumi refers to herself in the third person, which is a rather childish way of talking, but not nearly as strange as doing so would be in English. The localization of the manga has her speak in a childish way, such as "I'm worried! Dat's all!"
Writer Copout: The latter half of Mirio's fight against Overhaul, due to how lopsided the matchup seems for a Quirkless Mirio. Overhaul's ability to heal himself, pop anyone he touches like a zit, and reshape an entire battlefield already makes him a Superpower Lottery winner. Adding in that mortally wounding Eri would be an Instant-Win Condition for Overhaul, and Mirio continuing the fight for even five minutes becomes outright miraculous. Many fans felt more than a bit cheated that what was sure to be an impressive battle, showing Mirio's potential to become a hero without his Quirk, was almost entirely skipped over outside a handful of panels. This was especially underwhelming in the anime, as the climax of Mirio's character arc became a slideshow of stills essentially cut right from the manga.
WTH, Casting Agency?: The general consensus for the Latin American Spanish dub of the series is that the Florida side of the cast is a disappointment within the fanbase compared with the Movies' cast done in Mexico City. Not even the international collaboration with the rest of the countries can save the dub.
