Quirk: One For All (Formerly)

"It's fine now. Why? Because I am here!"

Japan's highest-ranking hero, who acts as a pillar of hope and justice for heroes everywhere to follow. His mere presence strikes fear into the heart of villains all around the world, as none can stand up to his massive power. There's no need to fear! Why? Because All Might, the Symbol of Peace, is here!

Unbeknownst to the world at large, however, is that All Might's great power is not his own, as he was actually born Quirkless. In truth, the Quirk he holds is one that was passed down to him from his mentor, and he's the eighth person to hold it. He's held the power since he was a mere teenager and has used it to become the Symbol of Peace he's known as today. Unfortunately, due to an intense battle with a powerful supervillain in his past, his body has significantly weakened. Now, he can only do hero work for up to three hours a day, and, once his limit is reached, he becomes a lanky, skeletal man who constantly coughs up blood. Only a select few staff at U.A. know this, and even fewer know the true nature of his Quirk. The story of My Hero Academia follows his successor, Izuku Midoriya, as All Might teaches the young man how to hone the immense power he's been gifted with.

"One For All", the Quirk he inherited, has stockpiled the power of its previous owners, significantly enhancing all of his physical abilities to a superhuman level. This results in unbelievable levels of strength, speed, agility, and durability that make All Might nearly invincible. However, due to an injury he suffered, this power can only be accessed for short amounts of time, with the duration further lowering over time ever since All Might passed the Quirk on to Midoriya.

  • 100% Heroism Rating: All Might is really popular as a hero, inspiring almost an entire generation to become heroes. Even during his fight with All For One when his emaciated form is exposed, people still continue to cheer him on. It says a lot about his character when even all but the most despicable of villains look up to and respects him as the gold standard by which decency, kindness, honor, and heroism itself is measured.
  • The Ace:
    • All Might is known as the greatest hero in Japan, and perhaps in the entire world, a Symbol of Peace trusted by every civilian, looked up to by every hero, and feared by ever evil-doer in his nation. This reputation comes from not only his unbelievable strength, which is far, far above almost anyone else in the world, but also from his strong charisma: his friendly personality and unstoppable drive to succeed make it hard not to love him, and his habit of saving people with a smile reassures everyone around him (except for the criminals he fights). Even though he's since been severely injured, putting a time limit on how long he can use his abilities, he is still far above every other hero. Gran Torino deconstructs this, noting that he took to One For All much more easily than Midoriya did, which caused his teaching methods, which worked for him, to be less effective for his protégé.
    • All Might can also be seen as the greatest holder of One For All. He was the most successful wielder of One For All, became the World's Strongest Man, and held the Quirk longer than his predecessors who died young. Furthermore, while his predecessors struggled against All For One and died, All Might is the only one who actually defeated All For One, twice, despite sustaining severe injuries in both battles. Heck, he even managed to maim All For One in their first battle. Unlike his six predecessors, All Might was born Quirkless and had only One For All. This actually benefitted him by making him immune to One For All's Rapid Aging effects.
  • Achey Scars: An interesting version of this is in play with All Might as it isn't his nemesis All For One that causes the injury he inflicted on All Might to ache, but rather any situation similar to their cataclysmic battle where they horribly injured each other will cause All Might's old wound to ache. This happened during the fight between Endeavor and Hood where Hood nearly killed Endeavor and the battle was insane, causing amazing damage and destruction. This echoed All Might's past fight with All For One, and watching the battle on TV caused All Might to grasp the area on his torso where he had been previously injured.
  • Achievements in Ignorance:
    • All Might cultivated One For All for forty years before giving it to Midoriya. In doing so, he unwittingly imbued One For All with a part of his own consciousness, a feat that surprised even Yoichi Shigaraki, the first user of One For All.
    • Unbeknownst to All Might, his vestige was relaying his research about One For All's past to the other One For All users, providing them with crucial information on the nature of the Quirk.
    • By choosing Midoriya, he inadvertently picked someone who could avoid the Rapid Aging effect none of the One For All bearers knew about.
  • Achilles' Heel: His injured side is especially vulnerable to damage. In general, he doesn't have Superman's invulnerability. In each of his fights, he's clearly felt it every time he takes a big hit, mostly due to his declining health, though his speed and power make landing those hits quite another story.
  • Action Hero: The Symbol of Peace and the #1 hero.
  • Actually, I Am Him: In Chapter 326, when confronted by the Hero Killer, Stain for daring to badmouth his idol, All Might reveals to him that he is that very person. However, it's implied to be Inverted as Stain is well aware of how All Might looks even in his emaciated form, having been spying on him and Izuku and witnessing All Might's anguish over his self-perception that he's a Failure Hero after everything he worked so hard to achieve has ended up All for Nothing due to the current societal collapse and being unable to dissuade Izuku from his self-destructive mindset, and Stain confronting Yagi over his self-rebuke is specifically to motivate him not to give up.
  • Affectionate Nickname: David Shield calls him "Toshi". All Might himself only calls him "Dave".
  • Affectionate Parody: Of classic superheroes.
  • All-American Face: While he's Japanese, he's definitely a send up to this type of character. He's blonde with blue eyes, which follows the usual Phenotype Stereotype of a Western foreigner, massively buff when powered up, wears a costume with a red, white, and blue color scheme, and constantly goes on about justice. Hell, his Smashes are named after an American city, several U.S. states, and the U.S. itself. It's established in My Hero Academia: Two Heroes and "Volume 0" that All Might departed for the U.S. in order to start his hero career and gain enough experience to confront All For One while staying out of the villain's reach.
  • All for Nothing: His final act as a hero. When facing All For One for the last time, he exhausted the remainder of One For All that he possessed to defeat the villain in the hopes of ending his threat for good. He succeeded, but was reluctantly forced to retire from hero work as a result. Immediately following the war with the Paranormal Liberation Front, All For One used his control of Shigaraki to free his original body from Tartarus alongside many other villains, rendering All Might's final heroic deed and the sacrifice of his Quirk for naught. This is discussed in Chapter 326 when Stain confronts a depressed and self-depreciating All Might. Stain takes the former hero to see a civilian woman who was the last person All Might saved cleaning a public statue from vandalism, and points out that just because All Might failed to prevent the threat of AFO from continuing, the lives he saved and inspired give hope that the next generation of heroes will be able to defeat that threat in the end.
  • All-Loving Hero: He used his incredible power to become the Symbol of Peace, and would go out of his way to help everyone.
  • All Your Powers Combined: Unlike Midoriya, he didn't have access to this aspect of One For All. However, As Armored All Might, his suit and support items are designed to mimic the abilities of Class 1-A, showing both how his students have inspired him and how closely he's watched their progress to be able to use their techniques effectively.
  • Asskicking Leads to Leadership: All Might defeated so many villains that he became the #1 hero and the Symbol of Peace.
  • Awesome, but Impractical:
    • His state post final battle with All For One and burning out the last of One For All's power. All Might can still shift to his larger muscled form, but he can only maintain it for a few seconds at best before he goes back to normal. At most generous, he'd be able to get out one attack with it, and afterwards he's reduced to a scrawny man coughing up blood and in crippling pain, so there's no way he can even maintain hero work, much less stay the #1 hero.
    • To buy time for Midoriya to defeat Shigaraki, All Might converts his Cool Car, Hercules, into a suit of Powered Armor with the help of Melissa Shields. This armor is equipped with gadgets designed to imitate the Quirks of everyone in Class 1-A, making All Might a force to be reckoned with and he holds his own against his old nemesis despite the power disparity. However, these same functions make the armor ruinously expensive. Author's notes mention that All Might spent almost every penny of his considerable wealth to have it finished in time. In addition, only someone as experienced and knowledgeable as All Might could possibly use it to its full potential.
  • Awesomeness Is a Force: Even in his diminished form, long after having fully lost any remnant of One For All, he is still All Might at the core. His sheer strength of will is intimidating enough to get small fry villains to back off in a way that directly contrasts Stain's Killing Intent.
  • Badass Adorable: Much like Major Armstrong of the Fullmetal Alchemist franchise, All Might is a musclebound sweetheart whose 120% sincerity and childish enthusiasm in bringing hope and joy to everyone around him makes him as cute and lovable as a big old teddy bear; and he'll readily hug you like one too if you need a kind and caring shoulder to cry on.
  • Badass Boast: His catchphrase is actually a deconstruction. He insists that, as bringers of hope, it's vital for heroes to boast with total conviction to reassure those around them.
  • Badass in a Nice Suit: He wears a flashy gold pinstripe one while teaching at U.A., as well as when he does interviews on TV. This is subverted in that while he's certainly badass, he never gets to fight while wearing it.
  • Badass Normal:
    • After losing One For All, All Might still has the capability to avoid some seriously dangerous situations and stare what should all but be his death straight in the eyes. It's enough to make even villains that consider him a pathetic shell of his former self think twice.
    • In the Final War arc, knowing that it was all but a Heroic Sacrifice begging to inevitably die if he did it, All Might uses a Powered Armor and marches headlong into fighting All For One directly. Not only does All Might show that he didn't strictly need his Quirk to be badass thanks to all those years of experience, but he knew that it would be such a complete and utter insult to All For One that it would make his foe waste precious time trying to spite All Might. The plan worked, albeit with All Might put on the brink of death afterwards, and Bakugo at the last moment preventing him from becoming Half the Man He Used to Be.
  • Badass Teacher: He becomes a teacher at U.A. He will also give a beating to anyone who tries to make his students suffer. He actually isn't a badass at the teaching part of this until he loses the ability to dish out said beatings.
  • Baritone of Strength: Being the strongest hero around, All Might sports a notably deep voice in both the Japanese and English versions. With that said, his frequent Large Ham tendencies tend to downplay this in more humorous scenes.
  • Becoming the Mask: Inverted and zigzagged. The All Might everyone knows is genuinely who he was at the time, but it's still exaggerated and it became difficult keeping it up all the time. Eventually, All Might became a mask worn by the depressed Toshinori. He eventually voices concern that the mask was ever sincere at all, although Stain assures him it was.
  • Berserk Button: The mere sight of All For One manages to piss off All Might beyond measure.
  • Beware the Nice Ones: He's almost always smiling and is the type to always lend a helping hand to anyone in need. The key word is almost. If you somehow manage to get him to stop smiling, you know you're in for it. Case in point. All Might may be a Badass Adorable but he also fought All For One and blew off the villain's eyes, ears, and nose with a devastating punch, rendering him faceless, literally. All For One's upper face was mostly made up of gruesome scar tissue until he used the Rewind drug.
  • Big Damn Heroes: He does it quite often in the series, most notably in USJ arc.
    • In Vigilantes, he comes to the scene when the Sky Egg starts to fall and puts it back into place, saving the heroes and civilians inside of it. Even when the remnants of the Bomber Villains become a giant monster, he deals with it again.
  • Big Good: A pillar of hope and justice for the world, with many aspiring to follow his example. Fittingly enough, he's thus the only one who matches All For One in terms of power. All Might himself invoked this, as he felt society needed a Big Good in order to not collapse.
  • Black Eyes of Crazy: Averted, of course, since he's not remotely evil; but his eyes are black with tiny, brightly glowing blue irises. It's mostly shown in his weakened state. Interestingly, Two Heroes shows that he once had ordinary blue eyes, and "Volume 0" also shows him with normal eyes, implying he started looking like this as he got older. He had his current black shaded eyes in his "debut video", which is presumably when he came back from U.S. to Japan.
  • Blood from the Mouth: Happens to him frequently in his weakened form.
  • Blow You Away: His super strength is strong to create powerful blasts of wind. These currents are strong enough to level a city block or generate enough air pressure change the weather. In addition, he uses these wind blasts to achieve Not Quite Flight by punching and/or kicking while in the air to propel himself in the opposite direction.
  • Body Horror: His weakened form is extremely emaciated, constantly vomiting blood, and horribly scarred just near the ribs. Parts of his organs, in fact, seem to be gone. In the second OVA, his weakened form is so mangled and scrawny-looking that he's mistaken for a zombie by the girls of Class 1-A who hadn't been infected by the zombie virus Quirk. Then the actual infected zombies mistake him for one of them, simply patting him on the shoulder and walking past him rather than biting him.
  • Boisterous Bruiser: He actively cultivates this image as part of his desire to be a Hope Bringer, laughing loudly in the face of danger and always flashing a bright smile no matter how hopeless things seem.
  • Brains and Brawn: When he was paired up with Sir Nighteye, he was the brawn of the duo.
  • Broke the Rating Scale: All of his official stats are 6/5, which is appropriate for The Ace who is effectively this world's equivalent of Superman.
  • Broke Your Arm Punching Out Cthulhu:
    • Downplayed when he beat All For One the first time around: All Might defeated All For One and destroyed his criminal empire, but was permanently and grievously wounded himself. The downplayed part comes in that All Might's injury only limited his hero work, and otherwise he went on the achieve everything he wanted to do while All For One is on life support 24/7 and was permanently crippled as a result (not to mention blind), taking the intervening years just to recover enough to become an active threat again, meaning All For One came out of it ultimately worse than All Might.
    • An interesting take given that it is two Cthulhus broke their arm punching out each other. All Might put everything he had into taking down All For One during their climactic battle, at a point when it was already hard for him to hold his hero form for more than an hour. The effort drained the last of his energies, and now he is more or less permanently reduced to his normal state, only able to maintain his hero form for a few seconds. While this was bound to happen eventually given his passing on of One For All, this is the official story for how he lost his powers.
  • Broken Ace: Except for a few individuals, the population is not aware that All Might is actually in critical condition and his injuries limit the usage of his Quirk (until his second fight with All For One). Five years ago, many of his closest associates suggested he should quit and appoint a successor. All Might declined in order to maintain his image as the Symbol of Peace. Eventually, he does appoint Midoriya as his successor.
  • Brought Down to Badass:
    • His ability to use his Quirk had been steadily declining since his previous battle with All For One. This decline only speeds up after passing over One For All to Midoriya. He's still the strongest character in the entire series until he loses his Quirk during the final battle against All For One. Even without his Quirk however, his years of experience as the top hero are still there as he outmaneuvers an assassination attempt and willingly stands up to two-bit thugs knowing full well that he's at a disadvantage.
    • He had a suit of Powered Armor made so that he can fight if absolutely needed. As shown when he finally busts it out against All For One, he still knows how to fight.
  • Brought Down to Normal: Since giving Midoriya One For All, he finds that he's slowly losing his power over time, and it will eventually stop working completely. This finally happens at the end of Chapter 94 after using the last vestiges of One For All to finally KO All For One.
  • Brutal Honesty: When Midoriya sees All Might in his true form for the first time, the latter talks about the harsh reality of being a hero. He also tells him that while there's nothing wrong with having a dream, he needs to be realistic about his situation.
  • Calling Your Attacks: In reference to how he's based off of Silver Age Western superheroes, he shouts out the names of his attacks, which are American-themed.
  • Cannot Spit It Out: Upon seeing how determined Midoriya was to prepare for his eventual battle with All For One, All Might cannot bring himself to tell Midoriya that Nighteye foresaw his potential future death. Midoriya eventually discovers the truth.
  • The Cape: Definitely. It's almost to the point of parody.
  • Captain Geographic: All Might has a clear American theme to his attacks, which are all named rather unsubtly after American locations from a city to states to even the entire country, he's a big, tanned blonde in red white and blue, and he drops Gratuitous English like it's hot. Out-of-universe, this is a reference to the commonality of Captain Patriotic superheroes in early superhero comics. In-universe, it's explained by how he moved to the U.S. when he was first starting out as a hero (to both gain experience and avoid All For One), then when he returned to Japan, adopted his history in the U.S. as his gimmick.
  • Career-Ending Injury: After years of fighting with many of his internal organs all but destroyed, All Might burns out the remaining embers of One For All in his second battle with All For One. Afterwards, he's forced into retirement as all he can do is power up for seconds at a time.
  • Cassandra Truth: Midoriya tells him that he wasn't the one who moved his fingers and activated his Quirk during his brainwashing at the U.A. Sports Festival. All Might doesn't buy it at all, and tells Midoriya that the vestiges merely inspired his own willpower. Midoriya buys it and accepts All Might's explanation. Over a hundred chapters later, All Might gets proven wrong when Midoriya has a interactive dream and his Quirk turns on by itself. The seven deceased wielders really did break his fingers in that match.
  • Character Catchphrase: "I am here!/I have arrived!", Japanese: "Watashi ga Kita!" while making a Dynamic Entry, which results in lots of joke variations in the Japanese version. He also occasionally says the school motto "Plus Ultra!" when trying to be inspiring or when showing off.
  • Celibate Hero: Thanks to being Married to the Job, romance wasn't ever on his radar.
  • Characterization Marches On: When first shown, All Might's teaching methods sometimes closed in to sheer jerkiness and meanness, such as sitting on a refrigerator and making Midoriya carry it, ignoring Midoriya to talk with some girls, etc. This same sort of behavior does not show up again, and he's shown as having much more professionalism than that.
  • Character Tics: When speaking to those younger than him, All Might refers to boys as "[last name]-shounen" and girls as "[last name]-shoujo". In English, he refers to them as "Young [last name]", regardless of gender.
  • The Chooser of the One: As the current wielder of One For All, he chooses Midoriya to become his successor. It's later revealed that this was a very impromptu decision, since he was already being pressured and advised to choose someone else before meeting Midoriya.
  • Chronic Hero Syndrome:
    • Played partly for laughs, but prior to the U.A. villain invasion, All Might stepped in to defuse a tense hostage situation, then moved on to stop a hit and run driver, and then... well, his commute to work ended up taking up all of the time he had that day for the use of his powers.
    • Comes up again in the Vigilantes prequel. Tsukauchi actually learned All Might's Secret Identity because he kept rushing off to save people while they were having coffee.
    • Deconstructed in a way because hero work is a highly regulated position of civil service, like a policeman, he must keep up paperwork for all his heroics, and he is far behind in paperwork because of it.
  • Civvie Spandex: After he adjusts to living his life as his emaciated self his new "hero" suit is just an All Might-branded track suit.
  • Cool Car: In the aftermath of the "Paranormal Liberation War" arc, he drives an armored sports car named "Hercules" which acts as his mobile base of operations during the "Dark Hero" arc. Chapter 396 reveals it was developed by Melissa Shield as a hidden support item which reassembles itself into an All Might-themed Powered Armor specifically meant for fighting All For One in close-range.
  • Creepy Good: A Downplayed example because he still usually acts like his bombastic, Large Ham self, but All Might's depowered form is genuinely unsettling to look at, with his near-skeletal, elongated body proportions (especially his over-long neck), creepy black eyes, frequently-exposed teeth that no longer form the kind of reassuring grin he wears in his powered form, wildly spiky but ragged hair, and tendency to spontaneously puke blood.
  • Cruel to Be Kind: At the start of the series, he bluntly tells Midoriya that there's little hope of him being a hero. Unlike Bakugo, who did it to belittle Midoriya, All Might believes that Midoriya can find a similar goal that better suits his abilities. He changes his mind and makes Midoriya his successor after seeing Midoriya try to save Bakugo.
  • Cuddle Bug: All Might is always there to give you a reassuring hug of hope to lift your spirit out of sadness and despair, and is never shy about using it as a gesture of how much he loves you.
  • Death Glare: He gives off an incredibly potent one, whether it be against villains who threaten his students, or even when he is acting out the part of a villain in Class 1-A's exercise against Midoriya and Bakugo. When you see that glare, you can try to run, but you probably won't get very far. Even being depowered does not diminish its strength - as a couple would-be hit-men find out.
  • Death Seeker: Downplayed and ultimately defied. As the series goes on, we get an idea of just how deep into depression he was at the start of the series. He lost his sense of identity and self-worth with his injury, on top of getting a seven-year prognosis from Sir Nighteye. He neglectednote  or forced awaynote  those he was close to so he could ignore his problems, and spent years play-acting his prime while waiting for his death to come, letting those still around himnote  make his decisions for him. Midoriya's actions for Bakugo reignited his spark, and after accepting his retirement and new role as a teacher he quietly admits to Aizawa that he wants to live.
  • Deconstructed Character Archetype: The series uses All Might to pick apart the implications of having a superhero who's The Cape and the Big Good, in several different ways:
    • First off, All Might himself is actively putting on the facade specifically for the sake of giving people someone to look up to. He genuinely is a good person, but the pressure of having to uphold that image repeatedly causes him to doubt whether he really is as much of a hero as he makes himself out to be.
    • All Might essentially is the ideal hero, meaning that he may have set the bar for superheroism a bit too high. On the hero side, it means that other heroes end up with inferiority complexes and/or serious envy when they can't measure up. On the villain side, a number of villains do respect him, but think every other hero who doesn't stack up to All Might is obviously a false hero who must be eliminated. Then there's the fact that being the Big Good makes him a target for the villains who want to destroy the hero establishment.
    • When All Might retires after using up the last of his powers, it creates a minor crisis as there's nobody else capable of serving as the series' Big Good. It turns out staking everything on one ideal hero is a bit of a problem if the hero can't keep being a hero for whatever reason. In fact, the people responsible for the first provisional hero license exam following All Might's retirement put a strong emphasis on teamwork so society would begin to focus on several heroes at the same time.
  • Defeating the Undefeatable: He managed to succeed where all others, including his predecessor holders of One For All, failed and defeated All For One twice. Albeit at a heavy cost both times.
  • De-power: As a result of giving One For All to Midoriya, over the course of the series, he began to steadily lose his ability to use the power left in him. This finally reaches its conclusion when he uses up the last of it in his fight against All For One at the end of the Hideout Raid Arc, permanently robbing him of his powers and forcing him to retire.
  • Determinator:
    • When it comes to protecting the innocent and punishing evildoers, All Might simply will never give up. Even when he's nearly exhausted all of the energy he needs in order to hold onto his muscle form, he manages to unleash Rapid-Fire Fisticuffs on the Nomu attacking USJ, with each individual punch being even stronger than usual:
    "A real hero...will always find a way for justice to be served!"
    • During his rematch with All For One, All Might is practically Quirkless and is running on fumes, while All For One has over a dozen super strong Quirks. Despite the dire odds, All Might defeats All For One, albeit he loses his powers forever and fractures his arm.
    • Even after losing One For All, All Might has the guts to to fight All For One for a third time. This time, All Might employs an armoured suit based on the Quirks of his students to fight All For One, and actually manages to put up quite the fight.
  • Deus ex Machina: In Vigilantes, he is recognized and described by the Big Bad as one, which justifies that he works in the story as one as well.
  • Deuteragonist: While the series as a whole is a Coming of Age story for Midoriya, All Might's influence and character arc drives the story just as much as Midoriya's journey, so he shares this role with Bakugo.
  • Disability Immunity: All Might was born Quirkless, which made him immune to One For All's Rapid Aging side effect. All Might went on to wield One For All for forty years, much longer than any other wielder.
  • Double Meaning: All Might's parting word after defeating All For One: "You're next." To the masses, it's a warning to the villains at large. To those in the know and Midoriya in particular, the torch has been passed and the age of All Might is over.
  • Dumb Muscle: In his youth. In stark contrast to his successor, All Might never had any problems physically using One For All like Midoriya does, but he lacked the sharp mind his student possesses. It worked out for All Might as he became a Genius Bruiser. Unfortunately, All Might admits that because of how different they were as young men physically and mentally, this makes it hard for him to teach Midoriya at times because he legitimately doesn't understand some of the problems the latter is having.
  • Dying Moment of Awesome: Rare non-fatal example. All Might ends his life as a superhero by using the last of his strength to put down All For One. Before reverting back permanently to his depowered form he gives a warning to scare criminals and strikes one last heroic pose before All Might as a hero is no more.
  • Dynamic Entry: Does this quite a bit, in contrast to his true form which staggers around beneath notice. It's to the point that "I am here!" is his catchphrase.

    E - L 
  • Eagleland: Predominantly because of his Silver Age traits, and despite being Japanese and not actually American, he tends to exhibit signs of the first type. For example, his workout plan for Midoriya invokes the classical American Dream in its name... and the notion that those born with nothing, can one day achieve the greatest success if they work hard to earn it. Additionally, as aforementioned, his attacks are American-themed. Two Heroes reveals that he actually did live in America for a time, which influenced his American-themed attacks and his hero costumes.
  • Embarrassing Ringtone: All Might's ringtone turns out to be a recording of himself saying "A phone call is here!", which is a play on his Catchphrase "I am here!". His fellow teacher and pro hero Eraser Head thinks to himself how lame it is.
  • Endearingly Dorky: Uraraka basically Squees when he gives a bombastic entrance, and makes a grand announcement that Midoriya is in his vicinity, only to offer to eat lunch with his protégé.
    Uraraka: He's like a maiden!
  • Engrish: In the Japanese version, he peppers his sentences with English words and phrases with varying degrees of success.
  • Enhanced Punch: His various Smash techniques are performed by channeling great deals of One For All's power into his fists, culminating in United States of Smash, which channels 100% of it.
  • Even the Loving Hero Has Hated Ones: All Might's strength is only rivaled by his kindness and he rarely uses excessive force in his fights. But his Arch-Enemy, All For One, is so reprehensible that All Might tried to cave the villain's face in the duel that crippled both of them. He gets bonus points for being the only character All Might refers to with the extremely hostile second-person pronoun "kisama" in Japanese.
  • Exact Eavesdropping: He walks by the hospital door exactly when Midoriya offers Mirio the power of One For All from outside of the latter's hospital room.
  • Face of a Thug: He's an Ideal Hero and an all-around swell guy, but the manga does sometimes acknowledge that his Non-Standard Character Design (in both forms) honestly looks a bit creepy by playing it for (usually comic) horror.
  • Famed In-Story: He's always swamped by reporters and fans because of how popular and famous he is. Even outside of Japan, he's immediately stampeded by the paparazzi as soon as he's spotted in a public area.
  • Fat Flex: He describes his superpower to be similar to this. Just like a normal human can puff their chest to look stronger, he too can redistribute his body's energy output to turn from a skinny bloke to a superhuman form. However, doing so puts heavy strain on his body, even more so after he got a lung ripped out in battle and so has had his transformational time halved.
  • A Father to His Men:
    • He technically has only one man, Midoriya, but their relationship is very akin of a father and son. All Might often treats and trains Midoriya in a manner similar to how a stern but loving father would do to his son, considering that Midoriya's real father never appeared in the whole series and is only mentioned once. All Might often borders on being a Parental Substitute.
    • He tried to pull this off with Bakugo once, with predictable results.
  • The Fettered: All Might clearly cares alot for achieving a peaceful and good society. He was willing to help, just about everyone and punish evil-doers. In contrast, his greatest nemesis, All For One, is The Unfettered, whom has proven to be just as formidable as he is.
  • First Friend: All Might ends up being the first real supportive friend to Midoriya after the latter had suffered from years of bullying, encouraging him through thick and thin to become a hero as he tries to guide him.
  • Flying Brick: All Might is a downplayed example of this trope. While he has most of the standard powers such as super strength, super speed, and super toughness, he doesn't have the power of true flight, but he still counts because he is able to achieve Not Quite Flight thanks to his super strength, which is powerful enough to create blasts of wind and air. He is able to use that to pseudo fly by punching and/or kicking the air and then allowing the momentum of the air blast to propel him in the opposite direction. This can be seen during the Final Exam Arc, in the climax of the first movie, and during his final battle against All For One in the Hideout Raid Arc.
  • Foreign Culture Fetish: All Might really likes American iconography. He apparently built up an appreciation for the culture when he spent the early years of his career there.
  • Foreshadowing: Whenever All Might switches between his muscular 'hero' form, and his skinny real body, the transformation is always accompanied by a burst of steam that obscures him until the switch is finished, with thin streams of steam being a visual indication he's about to forcibly revert mid-battle. Izuku even comments on it when the USJ attack is thwarted and Kirishima comes close to seeing All Might's real body, making it clear that it's an in-universe effect. The explanation for this is never really elaborated on, save that it seems to be a side-effect of All Might forcibly compressing his muscles into a battle-ready state and the fatigue his godlike power puts on him. However, it is later revealed that the core of One For All assimilates and absorbs the Quirk factors of those who hold it, passing those onto the next holder along with the stockpiled power. As a Quirkless 'empty vessel', Yagi was able to refine One For All's power almost to the point of passing the 'Quirk Singularity', upon which the full accumulated abilities of the power become available for the present holder. One of said abilities is revealed to be 'Smokescreen', enabling the Holder to generate clouds of smoke to block out one's vision around themselves, implying that Yagi's desire to hide his true form was allowing him to subconsciously partially access said Quirk. Driving the comparison, when Izuku fully unlocks Smokescreen, the anime has the smoke 'bleed' off his body in the same way All Might's stream did.
  • For Great Justice: As a boy, All Might came up with the concept of the Symbol of Peace to drastically minimize crime rate. His master, Nana Shimura, considered his goals to be weird, but she nevertheless took him as her apprentice and transferred One For All to him. All Might's successor also believes in this. This is also in stark contrast with All For One's For the Evulz motivation.
  • Fuel Meter of Power: After transferring One For All to Midoryia, All Might was left with just the remnants of the Quirk's energy. While he could still use it to power himself, the amount of energy he had to work with was finite and dwindled with each use. He was eventually left powerless after he was forced to use the last of One For All's remnants in his battle with All For One.
  • Fun Personified: He always wants to make sure everyone is in a good mood and often cracks hammy humor to that end.
  • Game-Breaking Injury: Five years before the main story, he took a devastating hit from All For One, which nearly killed him. He survived thanks to numerous surgeries, but his powers were disrupted that he could only use them three hours a day. When he powers down, he looks like a emaciated husk of his former self that constantly keeps coughing up blood. Regardless, he keeps up his hero duties, with only Midoriya and a few of the top officials knowing about what happened, as he doesn't wish for people to lose faith in heroes like him.
  • Genius Bruiser: He might seem like a Dumb Muscle with his rather goofy appearence, but in reality his intelligence is rated 6/5. He has quite a tactical mind when it comes to battle strategies and public speaking. That said, he still can be outsmarted by few people and in few arenas, he's far from the best teacher.
  • Gentle Giant: All Might is seven feet two inches tall. He is also always ready and willing to give a reassuring hug and his broad shoulders to cry on to anyone who is in sadness and despair. Even in his weakened state, he easily towers over any other character and is still as sweet.
  • The Glomp: He has a tendency to hug both David and Melissa very boisterously, even lifting them off the floor.
  • Gratuitous English: Frequently as part of his Large Ham tendencies:
    All Might: [in the Japanese version] Oh my... oh my... GOODNESS!
  • Hair of Gold, Heart of Gold: What All Might's true form used to look like. That is, before sustaining his near crippling injuries from All For One.
  • Handicapped Badass: All For One severely injured him before the start of the story. All Might went through numerous surgeries to stay as functional as he is now, but he still lost his stomach and a lung and regularly coughs up blood. These injuries also impair the use of One For All, as his body can't handle the strain for more than a few hours, a timeframe that shortens as the series goes on and he continues to push this boundary. Nevertheless, he managed to continue his heroics so successfully that he managed to completely hide his injuries and time limit from the public.
  • Henshin Hero: All Might has to consciously activate his powered-up muscled mode in order to use his Super-Strength and Super-Speed abilities. His actual form is a scrawny twig of a man.
  • Hero Does Public Service: Hardly any job seems too small for him. Be it punching out villains or going out of his way to save a cat from a tree as seen in the Vigilantes spin-off.
  • The Hero's Idol: All Might is the "Symbol of Peace", a powerful and inspiring hero who many aspiring heroes look up to, including Midoriya. Midoriya's heroism is inspired by All Might's bravery and selflessness in action, giving the quirkless boy a source of motivation to become a hero when no one else believes he can. It's Midoriya's own heroism that inspires All Might to train him as a successor.
    All Might: You too can become a hero!
  • Heroic Build: His muscle form, obviously. In his prime, he actually even looked like that.
  • Heroic BSoD: When All For One reveals that Tomura Shigaraki, a criminal that he's been pursuing, is actually the grandchild of his beloved mentor, Nana Shimura, All Might is horrified and filled with guilt. It takes a plea for help from a nearby civilian to snap him out of it.
  • Heroic Resolve: Despite his weakening condition, lives and breathes this and tends to inspire the same from the people around him. Midoriya in particular.
  • Heroic Second Wind: Over his time limit and severely injured, All Might is spurred into action again by the civilian he needs to save and the people looking on.
  • Hidden Depths: Much like his protégé, All Might is extremely strategic and resourceful even while Quirkless. Arguably, it took him once again becoming Quirkless to force this side of him out and he begins taking pages out of Izuku's book to formulate a plan that will trap All For One and split up his new villain army. This proves he's still very much a threat to villains everywhere, and will always be a thorn in All For One's side no matter what.
  • Hidden Eyes: In his heroic form, they gave him this as an aesthetic choice. Rather than the usual implications of this, it's to make him look more dramatic, rather than emotional or scary. It kind of helps that his eyes are shadowed out even in his skeletal form.
  • Hidden in Plain Sight: Prior to the public reveal of his true form, he freaks out during a visit to a hospitalised Midoriya when his classmates suddenly arrive, worried that they'll learn his secret. However, he looks so different that Ochaco mistakes him for a random visitor. This also happens in Training of the Dead, due to a zombie outbreak at the time.
  • History Repeats: Nana did the same "Now it's your turn" declaration to announce she was officially Passing the Torch to All Might as All Might did for Midoriya, pointing to them while the pupil cries. Thankfully, All Might survives his Last Stand, albeit at the cost of never being able to do hero work again. Which leads to hero society destabilizing.
    • Toshinori met Nana Shimura when he tried to fight off a bunch of low-level villains even though he was Quirkless, because he just couldn't remain on the sidelines, only for Nana to show up and effortlessly save him, the conversation implicating that this was when Nana chose him as her successor. More than forty years later, Izuku Midoriya's willingness to fight off a villain that was trying to kill someone else in spite of his Quirklessness, just because he couldn't remain on the sidelines, was what pushed All Might to pick him as his successor.
  • Hoax Hogan: A tall, blond, utterly musclebound American-themed Large Ham superhero who's a big proponent of Right Makes Might and mugging for the camera? He seems to fit.
  • Honorary Uncle: Melissa Shield, the daughter of All Might's best friend, David Shield, calls him "Uncle Might".
  • Hope Bringer:
    • Everyone feels better at the very sight of his presence in the field, as his status as the Symbol of Peace has reassured everyone of their safety from the moment he arrives:
    All Might: Never fear! For I am here!
    • He's also a deconstruction, as he deliberately invoked this trope by shaping himself into, as he puts it, a "pillar of support" for society. But with the injuries he's suffered, he can only act as a hero for limited periods of time and even that is starting to become too taxing. And what happens when you remove a support pillar?
  • Hour of Power: Thanks to his injury, at the start of the series he can only tap into his full strength for a few hours a day. After giving Midoriya One For All, this time limit gradually decreases. All For One explains that this is because All Might is now exclusively using the finite remnants of One For All within him as opposed to the full power he once had. The more he uses it, the less he has remaining and the weaker he becomes. At end of his fight with All For One in the Hideout Raid Arc, All Might permanently uses up the last remnants of One For All and loses his power.
  • Humble Hero: Despite his grandiose appearance and hammy demeanor, All Might doesn't concern himself with praise, recognition and accolades. All he really cares about is helping those in dire need and bringing them hope.
  • Hypocrisy Nod: He tells Midoriya that he can't recommend someone who's Quirkless becoming a hero because the pros have to risk their lives in the line of duty. Later, he's stuck watching a villain take someone hostage because he's hit his limit for the day when Midoriya throws himself into harm's way trying to help. It hits All Might like a freight train that he isn't living up to his own ideals and he forces himself to power up despite the pain to save both boys. He cites this as the reason he wants to give One For All to Midoriya. To add onto this, All Might himself was originally Quirkless before inheriting One For All just like Midoriya.
  • I Just Want to Have Friends: It's well commented in-series that he gave everything up in his obsession with being a hero, which got substantially worse after his injury. Even after retiring, Horikoshi confirmed he's really only pursuing a friendship with few individuals (e.g. scientist David Shield, detective Tsukauchi) school faculty and Izuku.
  • I Shall Taunt You: In the final battle against All For One. Despite being Quirkless and emaciated, All Might uses a Powered Armor to fight All For One. He roasts the villain, calling him a worthless demon lord for having all the Quirks, yet getting beat up by a Quirkless middle-aged man past his prime. All For One may have the power to steal Quirks, but as All Might points out, it is useless against a Quirkless opponent. All Might also points out All For One's predictable fighting style and exploits it to beat him up. All For One takes the bait and foolishly fights All Might, delaying his plan to reach Tomura.
  • I Work Alone: All Might very rarely takes on a sidekick, as that would run the risk of revealing his secret. However, Sir Nighteye's insistence in becoming his sidekick eventually led All Might to accept his help, making him an exception. Another exception was when he took on a sidekick while he was starting out his career in the U.S., that being David Shield. They eventually went their separate ways, however, with David becoming an independent scientist who won a Nobel Prize for Quirk research, though they still have a positive relationship.
  • Icy Blue Eyes: In his superhero form. They glow prominently whenever he gets serious.
  • Ideal Hero: Powerful yet kind-hearted, All Might continues to strive as an example of selflessness, decency, and justice in spite of his gradually declining powers. Part of his characterization is deconstructing this trope by showing just how much trying to live up to such ideals would negatively impact a person.
  • In a Single Bound: His main method of traveling around similar to the Golden Age Superman or the Hulk. He can combine this with his powerful wind attacks to achieve Not Quite Flight.
  • Incoming Ham: One of the first heralds of his arrival is a hammy, loud belly laugh.
  • Innocently Insensitive: Make no mistake, All Might is an extremely compassionate and kind-hearted person, but he does have his moments. Chief among them is never telling his protégé, a Quirkless fanboy, that he also wasn't born with a Quirk. This no doubt would've meant the world to Midoriya when they started training, but All Might didn't think to tell him until much later. Why? Because Midoriya never asked.
  • Instant Expert: He instantly got the hang of using One For All at maximum power when he obtained it, which contributes to his inability to teach Midoriya how to use it. This bites everyone in the ass later. Since All Might never struggled with the Quirk, he was incapable of having visions like the other wielders. This makes him have no real knowledge about the truth of One For All and All For One. As one fan described it, "He skipped to level 100 without watching the cutscenes and beat the final boss using a limited moveset."
  • Invincible Hero: He deliberately portrays himself this way. While, All Might remained undefeated throughout his career, not all of his victories were easy or without cost. Especially against All For One, both times.
  • Irony:
    • While regarded as the most powerful person of all time, not many know that All Might was born Quirkless. He was later granted One For All by Nana.
    • Despite being the physically strongest and most famous of all One For All users, All Might has almost no compatibility with the metaphysical aspect of One For All. All Might was able to quickly master One For All's physical abilities and never had to struggle like Midoriya. Unfortunately, that left him mostly ignorant about the vestiges of One For All. Only Nana and Midoriya have gone further.
  • I Was Quite the Looker: Downplayed. In his prime, All Might was a muscular hunk and a lightning bruiser, after his injuries and years of heroism has left him a skeleton with sunken eyes and hollow cheeks. His current appearance gives off a creepy vibe rather than unattractive one though.
  • Jock Dad, Nerd Son: The general dynamic between him and Midoriya. All Might's can-do attitude and physical abilities contrast with Midoriya's fanboyism and analytical skills.
  • Keeping Secrets Sucks: All Might has kept many secrets throughout his career. He's nearly killed himself in his attempts to cover up the truth of One For All, keep the public from learning of his crippling injuries, and keep All For One's name from becoming public knowledge. Despite all of this, the problem that causes All Might the most trouble is that he's scared that Midoriya won't be able to accept that while he looks like a larger than life figure, he's a mortal man and be it from natural causes or being killed, he will die one day and Midoriya will have to go on without him. He tends to withhold information from Midoriya about various parts of his past and the darker aspects of One For All, a choice that occasionally comes back to bite him. He finally decides to be open with Midoriya by the start of the final saga of the story.
  • Knight in Sour Armor: On the surface, All Might is kind and cheerful. However, he is also someone who is painfully aware of the grim realities of the hero career, something he tells Midoriya during their first meeting. All Might is still haunted by his master's death and how far he had to go to defeat All For One.
  • Lantern Jaw of Justice: His superhero form has this.
  • Large Ham: If his bold outline and loud personality didn't make it obvious, he is constantly spouting speeches about heroism and how it's important for him to be the Symbol of Peace.
  • The Last Dance:
    • His fight against All for One in Kamino becomes this to him, as he loses the last embers of One for All after he launches his United States of Smash.
    • He actually gets a second Last Dance during the Final War Arc, using Power Armor to goad All for One into a fight he won't be able to resist and distracting him into further wasting his Hour of Power.
  • Leeroy Jenkins: Gran Torino describes him as the "punch first, ask later" type.
  • Leitmotif:
    • "I'm Here!", a majestic orchestral piece suitable for the arrival of the world's greatest hero.
    • "Y.A.M. - Young All Might" is an energetic, groovy theme that sounds like it came straight out of the '50s with just enough of his future self's leitmotif to make sure the listener knows exactly who this song is for.
  • Lightning Bruiser: Very few people can keep up with his sheer strength and speed. His only weakness is the time limit that his muscle form has.
  • Like a Son to Me: In Two Heroes, Midoriya asks if it's really okay for All Might to take him to I-Island with him, since the companion pass in the invitation is supposed to be for someone extremely close like a relative. All Might assures him that through One For All, their bond is thicker than blood.
  • Limit Break: His most powerful move, only used against All For One, United States of Smash, where he channels all of his power into a haymaker so incredibly powerful that he creates a massive tornado from the sheer force alone (a tornado powerful enough to lift concrete buildings).
  • Lonely at the Top: All Might's goal was to become a pillar of hope for society, and he was very successful at it to say the least. However, it's implied that he burned a few bridges in the process, like in the case of his former sidekick Sir Nighteye, so that he could attain and keep such status.

    M - S 
  • Made of Iron: Given that Izuku's body increases in durability the more used to One For All percentages he gets, All Might qualifies as this himself, especially as he maintained 100% power and kept increasing One For All's overall strength for about forty years. It's why he's able to survive for so long fighting Quirkless against All For One during the climax of the series, being brutally smashed through and skipped across buildings. Even with the Powered Armor he's wearing, the impact of that would surely have killed an ordinary man.
  • Manly Tears: As much as he makes fun of Izuku for crying a lot, All Might himself isn't averse to doing it when he feels like so. Notably, he cracked a Tearful Smile when hugging his protégé after his second battle against All For One, and wept for the dying Sir Nighteye.
  • Married to the Job: It's heavily implied that he had no life or free time outside of his hero work before his injury, so much so that he can use his own real name and small form as a secret identity because no one knows him.
  • Master of All: He is best-known for his titanic strength, but he's also incredibly durable, fast, and smart. He's the number one hero for a reason. All of his stats are S rated (6/5).
  • Meaningful Name: His surname contains the kanji for "eight", referring to him being eighth wielder of One For All. It also has the character "tree/wood" in it, which likely refers to him being the pillar that currently upholds society as it is now. His hero name, All Might, is a spin on the word "almighty", showing his unmatched strength and status as the number one hero, and renowned Symbol of Peace.
  • Mentor Archetype: Deconstructed:
    • All Might might be a good hero, but he never had to teach anyone anything in his life. In fact, he only had two sidekicks in his career, and one of them was a scientist who's functionally Quirkless,note  while the other was a Badass Normal Guile Hero with a non-combat Quirk. As such, his tenure as a teacher at U.A. begins with him having no experience in teaching aspiring heroes how to use their Quirks more effectively. Unfortunately, this means that while he's the World's Best Warrior, he's also one of the worst mentors available. In fact, All Might's status as an awful mentor is lampshaded by almost every other mentor available and he has to learn how to teach from the ground up, even reading Teaching for Dummies.
    • In Midoriya's case, having transferred One For All in a hurry, All Might watches helplessly from the sidelines as Midoriya drags himself through the baby steps — like learning how not to break his whole arm — and ends up relying on other figures to put Midoriya in useful situations. At one point, All Might's old teacher Gran Torino feels obligated to step in. Not to mention All Might couldn't actually use One For All for any of its real abilities. When Midoriya obliterates his dorm room using a power All Might never had, All Might does nothing to stop him from participating in a mock battle later in the day despite two of the top staff at U.A. being in the loop that could. This leads to Midoriya nearly injuring or killing his classmates and himself while All Might could do nothing but watch.
    • When it comes to testing the students, he has a bad habit of going blatantly overboard and forcing the students to go all out, which causes them to force trauma upon themselves.
  • Mentor Occupational Hazard: An interesting example in that All Might is aware that this could happen to him, with him passing One For All to Midoriya with his already diminishing strength. So he repeatedly tells himself that it's likely that he won't be alive long enough to see Midoriya become the next Symbol of Peace. This is subverted in the villains' attack at USJ, the first time All Might appears without his signature grin, facing off against an Evil Knockoff of himself. He barely wins. In his final battle, after multiple arcs worth of his death being foreshadowed, it's staunchly defied. He uses up his remnants of One For All, which was going to happen soon anyway, and instead of dying, he vows to live and be there for Midoriya.
  • Moment of Weakness: In Chapter 1, he nearly abandoned Bakugo to a supervillain because he had reached his daily limit. Seeing the Quirkless Midoriya rush said villain in an attempt to save Bakugo convinced All Might to break his limit regardless of the risk to himself to save the day. This incident was what convinced All Might that it was time to pass on the torch and that Midoriya was a prime candidate for it.
  • More than Just a Teacher: Despite being the most powerful hero in the world, he takes a job at U.A.
  • Mr. Fanservice: Fitting for someone based off Superman, he was incredibly ripped and buff underneath that suit of his as a hero, and suffered Clothing Damage on quite a few occasions. Just look at him!
  • Mundane Utility: Sometimes he transforms into his muscular hero form momentarily just to look cooler, such as one instance where he transformed as a greeting.
  • My Significance Sense Is Tingling:
    • By Chapter 303, he can faintly sense when Midoriya is interacting with his shade in the Mind Hive of One For All due to physically holding on to the unconscious Midoriya's hand at the time while the OFA users were communicating together. Because of this he is able to intuitively understand the communication between the One For All users through his vestige self.
    • In chapter 413 All Might is able to sense the lingering will of Star and Stripe telling him through his vestige of the mental wound she left behind in Shigaraki's psyche after their fight. He can also feel that the power of One For All is being unraveled during Midoriya and Shigaraki's climactic fight.
  • My Suit Is Also Super: Two Heroes reveals that All Might's outfit was specially designed by David Shield to be incredibly durable, allowing it to withstand the incredible force of One For All and even that of a full blown natural disaster like a tornado.
  • Nice Guy: All Might's warm heart is as big as his muscles, and he's as kind as he is powerful. To him, giving people hope, joy and kindness is just as important, if not more so, than smacking villains into the ground.
  • Non-Standard Character Design: To go with his Large Ham personality, he is drawn in a thicker outline and has more shading than everyone else. He specifically has character design elements associated with the comic book creator Rob Liefeld, including a variant of the "Youngblood's disease" as his eyes are often hidden in heavy shadow or appear to be glowing. Ironically, this also means that despite being most inspired by a comic book art style it means he looks a more like a villain or morally dubious individual than he is intended to. His "true form" is also very different from everyone else, but in a more conventionally cartoonish and lanky sort of way. A few students even acknowledge this when he enters class for the first time.
  • Nothing but Skin and Bones: His "true form" is this. His body has wasted away after losing most of his respiratory system and having his entire stomach removed.
  • Not Quite Flight: All Might is able to do this thanks to his super strength being powerful enough to create blasts of wind and air. He is able to pseudo fly by punching and/or kicking the air and then allowing himself to be propelled in the opposite direction by the momentum of the air blast.
  • "Not So Different" Remark: Reveals to Midoriya that he used to be Quirkless himself before getting "One For All" and pretty much had the same drive he did when he was younger.
  • Obi-Wan Moment: Being dragged through the air by All For One to get to Izuku, All Might realizes he has one last chance to catch his nemesis unawares and further aid his protege in his mission to save the world. He reiterates his dream, being much like Izuku's own to become a great hero, before using the last remaining pieces of Hercules tech on his wrist mimicing Bakugo's Explosion as a Suicide Attack. This becomes a Defied Trope once All For One destroys the gauntlet, instead hoping to kill All Might himself for the entire world to see. Cue Bakugo rising up just in the nick of time to save him.
    All Might: I also can't abandon my dream. My dream to be the Symbol of Peace...
  • Oblivious to Hatred: He seems to view Endeavor as an acquaintance. However, Endeavor hates him and always brushes him off due to his desire to one-up him.
  • Occidental Otaku: Inverted. His costume, visage, and attacks all pay tribute to the United States of America, the birthplace of Quirk-powered heroes in the setting.
  • One-Man Army: In his prime, All Might could trounce dozens of villains in one go, save 62 different cities and towns in one day, and work for 72 hours continuously. Over the decades, he single-handedly destroyed All For One's criminal empire, with many of the villain's followers being imprisoned or in hiding.
  • Only Known by Their Nickname: Sort of. "All Might" is his hero name; but even in-universe nobody knows his real name, except for Gran Torino. Since he seeks to be seen as a symbol first and foremost, he conceals any kind of personal information about himself.
  • O.O.C. Is Serious Business:
    • When he arrives during the League of Villains' assault on USJ, All Might isn't smiling. This is All Might we're talking about here; he is always smiling while in hero mode, to the point where some fans had theorized that a permanent rictus might be a part of his transformation. The fact he isn't smiling makes it clear how he feels about the villains trying to get at him through his students.
    • When preparing for the mission to rescue Bakugo from the League of Villains, he expresses the desire to use a darker version of his "I am here!" catchphrase; rather than announcing his arrival in a way that makes people feel hope, he wants it to instill fear in the villains about how he's going to make them suffer for abducting his student.
    • All For One's very name fills All Might's mood to the brim with anger, given the villain's Lack of Empathy and manipulative tendencies. It's worth noting that All For One is the only character he refers to with "kisama", an extremely hostile and rude word for "you", in Japanese.
  • Origins Episode: Two Heroes tells, among other stories, All Might's backstory as a young hero. Volume 0, a tie-in manga released with Two Heroes, shows how All Might lost his mentor at the time, Nana, and moved to the U.S. to train far away from All For One.
  • Out of Focus: A rather tragic example. After losing his powers in his final battle with All For One, All Might retires. As such, he can no longer remain an active participant in the plot. He's well aware of it too and curses the fact that he can no longer help as the villains are only growing stronger. That said, he still does provide Midoriya with much needed advice on One For All, as well as continued moral and emotional support.
  • Papa Wolf: As the villains who attacked Class 1-A found out, trying to hurt his students is an easy way to get on All Might's bad side.
  • The Paragon: All Might isn't the Symbol of Peace just because he's incredibly strong, but because he's devoted to inspiring the good in others. Many of the world's other heroes and heroes-in-training aspire to follow his example. This is shown to have serious consequences once he finally has to step down, with the news filling the airways and inspiring long-suppressed criminal organizations to rise up again.
  • Parental Substitute: His interactions with Midoriya are akin to a father-son relationship. In Two Heroes, he says that the thing that connects him and Midoriya is thicker than water when Midoriya questions why All Might is inviting him to go to I-Island instead of a family member. (This often becomes outright official in fanfiction, with many stories having All Might start dating Inko and eventually becoming Izuku's stepfather.)
  • Parodies for Dummies: During their training, All Might goes around telling the students simple yet helpful advice. Aizawa is impressed at how capable All Might suddenly seems at teaching. He then immediately notices All Might's back pocket holding a book that's titled Even Dummies Can Be Teachers!, much to his surprise.
  • Passing the Torch: How One For All works. It's a unique Quirk that is nurtured and passed down from generation to generation.
  • Perpetual Smiler: In his powered up form, he nearly always has a giant grin on his face, though this is usually an act in order to reinforce the idea that he's an unassailable symbol of peace and justice.
  • Person of Mass Destruction: He's strong enough that, even when he only has the dying embers of One For All powering his body, his fist clashing with All For One caused this. An entire ward of Tokyo was devastated by their battle.
  • Phenotype Stereotype: Subverted. His blonde hair and blue eyes fit his Westernized All-American Face image, but he's actually Japanese.
  • Physical God: He's such a massive step up in power from the rest of the heroes that he's practically a deity in comparison, and the reverence that he receives from the public as the "Symbol of Peace" means that he is essentially worshiped as "the god of heroes". It's to the point where, when Midoriya and Bakugo faced him during their final exam, the normally arrogant Bakugo could only look stunned at him, and think to himself "he isn't just powerful, he is power." The fact that the normally arrogant and self-assured Bakugo could only describe All Might as power incarnate says all. Much less that this is against an All Might who's both past his prime and restrained by weighted wrist and leg bands so as to make the test at least theoretically winnable for the first year students.
    All For One: He's a true superhuman who is in another league compared to the rest of the heroes. A Deus ex Machina who seems to defy the laws of physics and fate itself at every turn.
  • Powered Armor: It turns out his Hercules car can transform into a suit of powered armor with weapons and powers based and named after all the Class 1-A students' Quirks. As Armored All Might, he uses it to fight All For One in one final battle.
  • Pre-Asskicking One-Liner:
    • During his fight with Nomu:
    "So, you were made to fight me, big guy?! If you can really withstand me firing at 100% of my power... then I'll have to go beyond that and force you to surrender!"
    • During his fight with All For One, just before delivering United States of Smash:
    (in response to his opponent's comment that his punch's gotten weak) "That's because I didn't put my back into it! United...States of... SMAAAASH!!"
  • Primary-Color Champion: As seen above, his hero costume contains blue, red, yellow and white.
  • Psychologist Teacher: Midoriya isn't the only student All Might tries to mentor after joining U.A.'s faculty as Bakugo and Todoroki also bring out his mentor side. He is also shown to be very encouraging to pretty much all his students.
  • Pyrrhic Victory: He managed to defeat All For One twice, but both times came at a very high cost to him and the public at large. The first time, All Might's respiratory organs and stomach were irreparably damaged, leaving him permanently weakened despite multiple attempts to repair the damage. The second time, he lost all access to One For All's power, was forced to retire from heroism. Despite successfully hauling All For One into custody, the chief of police declared the second round "a draw" between heroes and villains.
  • Rapid-Fire Fisticuffs: He beats the USJ Nomu by punching him 300 times.
  • Recoil Boost: New Hampshire Smash has All Might punch the air to redirect himself, often leading into an elbow strike. Even while holding way back, the force of this attack nearly snaps Midoriya's spine.
  • Red Baron: Known as "The Symbol of Peace" (平和の象徴, Heiwa no Shōchō).
  • Renowned Selective Mentor: Passing One For All is done very selectively, considering its power. Even without involving One For All itself, All Might has very strict standards for taking on an apprentice thanks to the dangerous secrets that any apprentice of his would inevitably have to learn. Of course, this is all done in secret with only a few in the know. The public at large knows he's only ever had two sidekicks, but they don't know that the reason is to make sure as few people as possible know about One For All rather than just because he's picky.
  • Required Secondary Powers: Those thick muscles aren't just for show. All Might has no issues with damaging his own body using One For All, unlike the lean teenage Midoriya, implying a superhuman level of durability to match his strength. Indeed, he can take things like Bakugo's explosions with some pain but no real danger.
  • Right for the Wrong Reasons: All Might gave One For All to Midoriya because the boy was a Quirkless person with a strong sense of justice, just like him making him mentally and emotionally fit as a successor. What All Might did not know at that time was that Midoriya, despite his scrawny frame, was the only candidate physically fit to inherit One For All. Had All Might transferred One For All to a Quirk user like Mirio, the strain of housing it in addition to his natural Quirk would have drained his vitality so much that he'd die of "old age" within a few years. Since Midoriya is one of the rare people in his generation born Quirkless, he is effectively an "empty vessel" that can hold One For All without suffering this effect, letting him carry it on indefinitely.
  • Samaritan Syndrome: In the aftermath of the mall incident, Midoriya asks him if there's anyone he hasn't been able to save. All Might acknowledges that he can't save everyone, but that's only even more reason to keep on a brave face for the world. In his prime, All Might was so determined to save as many people as possible that he rarely took time to sleep.
  • Scissors Cuts Rock: The first Nomu was designed to match the strength of his punches and absorb the impact of 100% of his blows. All Might responds by going beyond 100% to overload the Nomu's absorption capacity and send it flying.
    He said your Quirk was only shock absorption, not Nullification. That means there's a limit to how much you can take, right?
  • Screw Destiny: When Sir Nighteye predicted his demise, and he had never predicted wrong, All Might quite literally said that he would just change his own fate.
  • Secret Identity: Vigilantes reveals this is how he hid his weakened body from the public: by spending his time as All Might's "Secretary Manager" under his real name.
  • Secret Identity Vocal Shift: He speaks in a booming and enthusiastic voice fit for a superhero; as civilian Toshinori Yagi, he sounds tired and deadpan. This has less to do with preserving a secret identity and more to do with keeping up his image as the tireless symbol of peace and justice.
  • Showy Invincible Hero: What he is In-Universe. All Might is the strongest hero who is known for always winning his battles and saving everyone once he appears as the Symbol of Peace. Of course, the truth is a little more complicated. As the Symbol of Peace, he can't ever lose a battle or else the public's faith in him (and by association, the hero system) will be shattered.
  • Signature Laugh: One of the first heralds of his arrival is a loud, energetic belly laugh to reassure anyone who's in trouble that everything is fine now that All Might is here for them.
  • Sink or Swim Mentor: If you think Aizawa is bad, All Might is even worse. Any poor soul paired up with him as their teacher/mentor for the day should expect a merciless beating. Doesn't matter if you're only in your first year, All Might will take you as seriously as he would a villain. Gran Torino says that All Might isn't relying on this method by choice, but because he doesn't know how to be a proper teacher.
  • Slave to PR: Being a major source of inspiration for up and coming heroes for future generations in addition to being the Symbol of Peace and Hope, All Might doesn't show his weaker side to the public as it would destroy that image. When his secret is revealed to the public, however, they still respect him.
  • Smoke Out: Not traditionally, but whenever All Might transitions between his 'hero' and true forms, the effort involved in maintaining said state apparently causes a burst of stream to generate, obscuring him from view, which has come in handy a few times when his Hour of Power ran out and his secret was nearly exposed. Later revelations about the true nature of One For All imply that this might have actually been Yagi subconsciously accessing the 6th's smokescreen Quirk, in response to his desire to hide the true state of the 'Symbol of Peace'.
  • Smug Smiler: While this is usually never the case for his trademark smile as a hero, Chapter 396 has his Armored All Might form deliberately leave his mouth unguarded so he can rub his confident smile in All For One’s face which greatly angers him as planned.
  • So Proud of You:
    • Expresses this in as many words once he confronts Izuku after his reckless, but brave, intervention during the Kamino Incident that rescued Bakugo, thus clearing the way for him to fight All For One without having to worry about him as a hostage.
    • During the Final Battle, All Might reflects on the beginning of his journey with Izuku, with his final thoughts before his Suicide Attack against All For One being of his protege and how he's always been capable of being a hero. He expresses his pride and love for him as his adopted son before gripping All For One tight in a bear hug, initating his Heroic Sacrifice in an effort to lessen his burden as the last One For All user.
    Izuku (flashback): Can someone without a Quirk become a hero like you?
    All Might: You can.
  • Spin Attack: Oklahoma Smash.
  • Stepford Smiler: Puts on a brave face in hero mode to live up to his reputation as a symbol of justice, but is all too aware that he's a fallible human being and that the day is rapidly approaching when he can't be a hero anymore. Chapter 92 reveals that he does this on the encouragement of his mentor, who argued that the people he rescues have been through a lot of trauma, so he should smile so as to save their hearts as well as their lives.
  • Stock Shōnen Hero: He was a Quirkless underdog who ended up becoming The Ace who wanted to be the #1 hero. His skills are so amazing that he was the most successful wielder of One For All, became the World's Strongest Man, and held the Quirk longer than his predecessors who died young. Furthermore, while his predecessors struggled against All For One and died, All Might is the only one who actually defeated All For One, twice, albeit he sustained severe injuries in both battles. Heck, he even managed to maim All For One in their first battle. He even has his own Stock Shōnen Rival in Endeavor. Horikoshi has revealed that All Might is somewhat inspired by Son Goku, who is the shonen hero.
  • Story-Breaker Power: In his prime, he could defeat anyone except for All For One without any trouble at all. Even in his greatly declined present-day state, the plot often still requires a Drama-Preserving Handicap just to give other characters something to do.
  • Strong and Skilled:
    • All Might has Super-Strength, Super-Speed, and Super-Toughness, which he combines with his keen tactical sense and refined punch techniques. The official guide lists him as the only hero who has 6/5 points in every hero category (power, speed, technique, intelligence, cooperativeness). Even though he is way out of his prime, he is still the top ranked hero in the world. This is later played with when it's revealed that he never had any affinity for the more metaphysical aspects of One For All, and as such he could never interact with the vestiges nor gain their Quirks. However, he mastered the physical enhancement aspect of One For All so completely that he was able to defeat All For One twice using just this one fragment of the power.
    • As Armored All Might, he makes up for being weaker than he used to be by being very skilled with the weapons and powers of the suit. This is why he makes it a point to get into melee range of All For One and stay there, as he has a gigantic edge against All For One in terms of melee skill.
  • Suicide Attack: His mad rush against All For One using his Hercules Powered Armor before he can reach Izuku and Shigaraki amounts to this, taking a consistently horrific beating but striving to wear down his old enemy enough for him to rewind out of existence thanks to using a copy of Eri's Rewind on himself. And once All For One proceeds through the last stretch of his journey to reach the two young men after stripping away said armor, All Might whips out the last ace up his sleeve: a gauntlet bomb strapped to his wrist he triggers on himself and All For One in midair as a final act of resistance. However, All For One anticipates this and destroys the bomb before he can, explaining he doesn't want All Might to choose how he wants to go out. All Might instead comes very close to being split in half before Bakugo rises from Edgeshot's emergency medical attention, ready to save his mentor while Izuku deals with Shigaraki.
  • Super-Speed: In his massively declined present-day state, roughly half the speed of sound (as he was able to cover 5 KM/3.1 mi in 30 seconds, which equates to roughly 600 KM/H or 375 mph). All For One notes that this is much slower than he used to be - during Vigilantes he once traveled from the site of a case in Hokkaido back to his headquarters in Tokyo (about 1300 km/812 mi) in a matter of minutes.
  • Super-Strength: One For All. The strength boost also provides Super-Speed and In a Single Bound.
  • Super-Toughness: To a degree. He is able to take a point blank blast from Bakugo's explosive gauntlets without slowing down and is able to get blasted through several city blocks worth of buildings and keep on fighting. Although beings on his level of power such as All For One can hurt him, he's basically Nigh-Invulnerable for almost anyone else.
  • Superheroes Wear Tights: Every hero costume he has is a variation of this.
  • Superior Successor: As One For All is cumulative in nature, every successor becomes stronger than their predecessor. In All Might's case, he was by far the most successful wielder of One For All- he wielded One For All for forty years, ruled as the number one Pro Hero of Japan and defeated All For One on two occasions, crippling the villain. Although Midoriya is destined to surpass All Might in power, the latter was far better than Midoriya in other ways. He was able to use One For All perfectly the moment he got the power and had near infinite confidence. His successor's luck with using the power so far has been a trainwreck that has nearly crippled him and is burdened with severe self-esteem issues. Luckily, Midoriya still has a long road ahead.
  • Superman Substitute: All Might is the My Hero Academia universe's Superman equivalent. In his prime, he was far and away the strongest hero in the setting, boasting immense strength, speed, endurance, and courage (making him closer to the Golden Age version of Superman, lacking his other powers such as Flight note  and Eye Beams). He uses those powers to inspire hope in others, making himself into the Symbol of Peace. He also has a somewhat similar outfit, being a Primary-Color Champion dressed in a tight full-body suit. Although he's Japanese, he does have a strong American influence, having trained in the USA and naming his attacks after the States.

    T - Y 
  • Tactical Withdrawal: Volume 0 shows that once All For One killed Nana Shimura, All Might was his next target. Gran Torino intervened and sent him abroad as soon as he graduated U.A. so he could train and gather experience somewhere where All For One had less influence and wouldn't be able to go after him so easily.
  • Take a Third Option: After defeating All For One, the remnants of One For All in him run out, and he's facing retirement. That said, the world still needs a Symbol of Peace before the torch is fully passed to Midoriya. Thus, he says "Next, It's your turn" towards the camera, and delivers it in a way that does both; the general public think he's out to get any other villains out there, inspiring hope for the people and fear from the villains, but Midoriya knows he actually means it'll soon be his turn to be the Symbol of Peace.
  • Taking You with Me: While aware it won't kill All For One directly, he does this in spirit at the climax of the series, operating on his conviction that wearing the man down enough will give Izuku a better chance to win instead of contend with two fully powered villains possessing the All For One Quirk.
  • The Teetotaler: After losing a good chunk of his digestive tract in his first duel with All For One, he has no idea whether or not what's left can safely process alcohol, so he's sworn it off to be on the safe side.
  • Technology Marches On: invoked He mentions this when he notes how Hatsume's special gloves for Midoriya are quite compact compared to the larger and bulkier stuff he used back as a rookie hero:
    All Might: So this is how compact they can make it these days...
  • Two-Timer Date: A variant. Tsukauchi arranged for meeting All Might, but had to settle with Mr. Yagi, All Might's "Secretary Manager". But things kept happening outside which caused Yagi to repeatedly excuse himself to the toilet, be All Might and save the day. In the end, it's the fact that he forgot to return the cat he just saved and failed to button his shirt and cover his All Might costume that tipped Tsukauchi that Yagi is All Might. Thankfully, he agreed to be his Secret-Keeper.
  • The Unchosen One: Like Midoriya, he was born without a Quirk into a world where being Quirkless was rapidly disappearing with no way to fight injustice, and only became All Might because he proved he was truly heroic. But unlike Midoriya and his predecessor, Nana, All Might has almost no compatibility with the esoteric aspects of One For All and remained ignorant of the Quirk's true power.
    Nana: Take more pride, Toshinori! You're not like the others who're born with what they have. You worked hard to win your power!
  • Unskilled, but Strong: Retroactively revealed to be this. He had no idea about the true depths of One For All, so he never was given the chance to use any of the powers within it, and only had the surface level abilities given to him. He mastered the raw power of the Quirk without using its greater skills.
  • Unstoppable Rage: Upon seeing All For One again after their last battle, he's seen visibly more pissed off than anyone has ever seen him be. All For One then proceeds to push a soft spot for All Might by mocking his master Nana Shimura, which makes him even more angry.
  • Vague Age: Subverted. Initially, his age was all but unknown, and All Might himself has never spoken of it. It is confirmed by the One For All predecessors that he wielded One For All for forty years. If Midoriya is to be used as a point of reference, All Might inherited One For All around the age of 15-16 and is presently in his mid 50s.
  • Variant Power Copying: During the Final Battle, All Might compensates for having burnt out all of his Quirk's power by wearing a suit of Powered Armor. This armor has various functions that imitate the Class 1-A students' Quirks, named after their hero aliases, such as Red Riot armor plating, Uravity and Ingenium jet thrusters, and the Great Explosion Murder God Dynamight, a last-resort suicide bomb.
  • Victory Through Intimidation: In spite of being rendered powerless after losing every remnant of One For All, he still caries the willpower of Japan's number 1 hero. Just him advancing towards two mooks with a resolute Kubrick Stare is enough for them to flee immediately, despite All Might having no realistic way to fight them off.
  • What the Hell, Hero?:
    • All Might often gets this about his teaching method toward Midoriya. Recovery Girl and Aizawa have both chewed him out for not going far enough to teach Midoriya how to use One For All without hurting himself and Gran Torino outright says that All Might is a terrible teacher. He gets chewed out again by Recovery Girl after his brutal spar with Midoriya and Bakugo came within a hairs-breadth of permanently disabling both boys.
    • He gives one to Midoriya for going with some students to rescue Bakugo despite the risk of injury, even hitting him with a Texas Smash in his weakened form. This is then downplayed as All Might turns the scolding into a So Proud of You speech, praising Midoriya for finding a way to rescue Bakugo without actually fighting any villains, and thus not technically breaking the law by doing hero work without a license. He promises to be a better teacher now that he no longer has One For All anymore.
  • What You Are in the Dark:
    • His initial Wax On, Wax Off training with Midoriya involves... cleaning up a trash-covered beach. All Might proceeds to explain that being a hero isn't just all about the big flashy stuff - the small, unglamorous things are important too.
    • His injuries and emaciated real form make most of his heroics a case of this. As his real form isn't recognizable as the great hero All Might, he can (and does in the first chapter) stand unnoticed in a crowd of civilian onlookers watching a villain rampage. When Midoriya, who's in the same boat, chooses to do something anyway, All Might realizes he's failing this particular test.
  • Why Won't You Die?: Played with. All Might as a hero is no more, but the ideals he instils in other heroes ensures his legacy lives on. All For One in particular hates this, as every hero that resists him from thereon makes it as if he's fighting All Might again, to the point of cursing one such hero as a 'spectre of All Might'.
  • Worf Had the Flu:
    • In Two Heroes, All Might is running on fumes due to the strain of maintaining his muscle form all day long, preventing him from just ending the fight as soon as he's freed from his restraints.
    • Every fight he has in the series proper is one he likely wouldn't have struggled against if he hadn't passed One For All onto Midoriya or suffered his injury. He states at his strongest he could've defeated the first Nomu in five hits rather than the over three hundred it took now.
    • His rematch with All For One is this. He has to spend most of the fight holding back to avoid harming civilians on top of being on the lingering embers of One For All. By the time he can go all out, he's at his limit. He still wins.
  • Workaholic: We never see him do anything that isn't related to training to be a hero, heroics, or trying to train others to become heroes. Back in his prime, he worked for 72-hours straight at least once, and is about to catch some much-needed shuteye when he gets a call for help from Osaka, instantly jumping back into uniform and leaping all the way over.
  • World's Strongest Man: All Might had Super-Strength and was the #1 ranked hero until his retirement. Throughout his career All Might remained undefeated, although he nearly lost his life when he fought All For One and sustained debilitating injuries. Nevertheless All Might's prowess was of another ilk. The insurmountable difference in the abilities of All Might and the second ranked hero Endeavor caused the latter to have a One Sided Rivalry with him.
  • You Never Asked: He justifies the fact that he hadn't told his protégé that he also used to be Quirkless this way, revealing it very casually. He also never told Midoriya that he once used support gear or that he doesn't use 100% power all the time.
  • Your Days Are Numbered: Sir Nighteye urged him to retire because his Foresight saw All Might dying a gruesome death. While there's some nuance to Sir Nighteye's Foresight, it's never been wrong before; as of current, All Might has between one to two years to live. But he and Midoriya are trying to change that fate. With Midoriya finally proving one of Nighteye's visions wrong, it's now possibility that All Might won't have to die in battle or from his injuries. It's also possible that Sir Nighteye's vision was undone before Midoriya proved it was possible, as All Might lost his ability to fight after defeating All For One.
  • Your Size May Vary: All Might's neck in his normal form ranges from normal, to noticeably long, to grotesquely long. He'll also vary from being almost as large as his towering muscular form to merely being a bit taller than most other characters.

"The people, the heroes, even the villains, I stand to set fire in their hearts."
