Toshinori Yagi - All Might
Debut: Issue 3 - If This Be My Destiny...!
Japan's greatest Hero and Izuku's lifelong idol. A man known for his incredible strength, boundless kindness, and unbelievable charisma, he's the Hero everyone aspires to be. His work in bringing down crime in Japan has led others to call him the "Symbol of Peace".
- 100% Heroism Rating: He's almost universally beloved for his heroism and kindness. The only people who don't like him are Villains and Endeavor.
- The Ace: He's the most powerful and respected Hero in Japan, beloved by the public and making short work of even the most dangerous of Villains in an instant.
- Adaptation Relationship Overhaul: In the original My Hero Academia, Izuku becomes All Might's successor and they develop an almost familial relationship that All Might describes as thicker than blood. Here, All Might has already found his successor but chases down Izuku to encourage him to become a Hero anyways.
- Arson, Murder, and Lifesaving: He confronts Izuku about running in to save Peter. At first he talks about how reckless and dangerous Izuku's actions were and asked what was going through Izuku's head when it happened. When Izuku explains that his legs moved on their own, All Might grins and says that this behavior is exactly what makes an amazing Hero.
- Big Damn Heroes: He shows up when the Prowler is threatening to blow a hole in Mount Lady's neck after Izuku interfered, swiftly defusing the hostage situation until Mysterio shows up.
- Blood from the Mouth: He frequently coughs up blood as one of the many consequences of his injury.
- Boisterous Bruiser: His entrances are heralded by his booming laughter and he's more than happy to call any Villain on their bluffs.
- The Chooser of The One: He has chosen his successor to the sacred torch of One For All, a unique Quirk that grows in power as it's handed from user to user.
- Demoted to Extra: In the original My Hero Academia, All Might is one of Izuku's closest confidants as the previous holder of One For All, frequently appearing in the story to offer him advice or explain more about the Quirk. Here, he has already found a successor, leading to far fewer appearances as they simply don't have the same relationship that they do in canon.
- Dynamic Entry: He makes his first in-person appearance in the story by appearing out of the blue and punching Prowler down the street while swiping the detonator from her hands.
- Game-Breaking Injury: Years before the story began, All Might lost his digestive system and half of his respiratory system in a titanic battle with his nemesis, All For One. As a result, his condition has been steadily deteriorating and he can only remain a hero for three hours a day, after which he's reduced to a husk of his former self.
- Hair of Gold, Heart of Gold: Has a head of golden blonde hair and is the kindest Hero imaginable.
- Heroic Fatigue: He became tired and cynical after years of being the Symbol of Peace thanks to the stress of being everywhere for everyone, maintaining his secret, and having to choose his successor. His passion for heroics was only restored when he witnessed Izuku rush into the fray to help Peter.
- Hope Bringer: His job is to bring hope to everyone in need with his arrival. When All Might is on the scene, saving the day becomes a certainty rather than a possibility.
- In a Single Bound: He usually gets around by leaping enormous distances with his Quirk.
- Incurable Cough of Death: All Might is frequently coughing because of his injury and he knows his time will come eventually. He lampshades it, lamenting how his new co-workers at U.A. see him as a man who could kick the bucket at any time rather than the Symbol of Peace he aspires to be.
- Lightning Bruiser: He's fast enough to create sonic booms when he's running at full speed and powerful enough to shatter androids with a single punch. He's also tough enough to be almost totally unscathed after a miniature rocket exploded in his face.
- Nothing but Skin and Bones: His "true form" after his injury is a shriveled husk of a man as the loss of his stomach and lung allowed his once powerful physique to waste away.
- The Paragon: His heroics have inspired entire generations of Heroes, including Izuku, to take up the mantle.
- Perpetual Smiler: He's known for having a wide grin on his face at all times to assure people that everything is going to be alright.
- Personality Powers: The archetypal superhero and The Paragon just so happens to have incredible Super Strength.
- Secret Identity: His real name and the nature of his Quirk are both kept from the public, which is a rarity among Heroes in the modern day. This is to prevent news of his injury from reaching the public and potentially destabilizing society.
- Showy Invincible Hero: Has a reputation for this thanks to his Large Ham tendencies and incredible power, but due to his injury the truth is much more complicated.
- superheroSobriquets: "Symbol of Peace" and "Number One Hero".
- Superman Substitute: Wears red and blue, keeps up a Secret Identity, and is the premier example of The Cape on his Earth. This is on top of being The Paragon and the World's Strongest Man.
- Super Strength: His Quirk gives him enormous strength, creating sonic booms as he approaches and easily dispersing a cloud of fog with a Shockwave Clap. He also tears through Mysterio's androids as if they were made of papier-mache.
- World's Strongest Man: He's by and far away the most powerful and successful Hero in Japan, if not the world.
- You Are Better Than You Think You Are: While it initially seems like he's going to chew out Izuku for intervening in the Prowler's attempt to kill Peter, he assures him that this willingness to rush in without a second thought is what will make Izuku an amazing Hero.
Nezu - Principal
Debut: Issue #7 - Boy Falls From The Sky
The principal of U.A. Although he's some kind of furry animal, his Quirk, "High Specs", grants him intelligence and calculation power far surpassing any human on Earth.
- Amplified Animal Aptitude: His Quirk gives him intelligence surpassing humans.
- Animal Superhero: He's a non-human Pro Hero of a school designed to train the next generation of superheroes.
- Being Tortured Makes You Evil: Downplayed. He was experimented on for being a rare animal with a Quirk and takes some sadistic pleasure in watching his students squirm. But he remains good-natured and is a respected Pro Hero. In fact, he shielded Izuku from the government, who would have "tested" him and his powers in hopes of replicating the process. That said, he's implied to be heavily enjoying having scientists prod Izuku in non-invasive and harmless ways, including conducting tests that require Izuku to remain unmoving while Strapped to an Operating Table and stripped to his underwear while conducting CT scans and other medical procedures.
- Big Good: As the principal of the top Hero school in Japan, he's informally this.
- Cartoon Creature: He's supposedly a mouse, but is the size of a dog and possesses a cat-like tail. Then there's his ability to hold onto things without a problem despite lacking opposable thumbs.
- Fully Dressed Cartoon Animal: He's fully clothed like any human despite being an animal.
- Good Is Not Dumb: Aside from being the smartest thing on Earth, Nezu is wary enough to background check all potential students at U.A. He's suspicious of Izuku's vast array of Combo Platter Powers from the get-go and decides to investigate them above All Might's complaints about it being unnecessary.
- Intellectual Animal: His Quirk is Super Intelligence, making him the smartest thing on Earth.
- Large and in Charge: Inverted. He's the size of a dog and the head of U.A.
- Mundane Utility: Super Intelligence is great for managing a world-class school and conducting investigations, but it's also great for figuring out how to hold things without opposable thumbs.
- Reasonable Authority Figure: He's wary enough to perform background checks on all prospective students but puts their welfare first above all. After determining that Izuku didn't get his powers from a certain suspicious individual, he tells Izuku that his admission was never in-doubt and that he'd simply be monitored closely as an unprecedented case, as he's more than earned his place at U.A.
- Rodents of Unusual Size: He's supposedly a mouse, but he's the size of a dog.
- Rugged Scar: Has one running across his eye as a memento of his days as a lab rat.
- Super Intelligence: His Quirk, "High Specs", makes him smarter than any human on Earth. This lets him run the finest Hero school in Japan, work as a Pro Hero, and even learn how to hold things without opposable thumbs.
- Surveillance as the Plot Demands: He has the testing grounds for the U.A. Entrance Exam littered with cameras to eye particularly promising aspiring students and watch out for cheating. The walls are also littered with sensors to track the output of certain Quirks and make sure they match what's been put onto the forms. Izuku's ability to make these sensors go haywire by phasing through them is what tips Nezu off that Izuku's powers aren't from a Quirk.
- They Would Cut You Up: As an extremely rare animal with a Quirk, Nezu was experimented on in the past, as evidenced by the scar running across his eye. This has made him understandably wary of the government, prompting him to shield Izuku from their "testing" by promising to have U.A. monitor Izuku's abilities instead.
Nemuri Kayama - Midnight
Debut: Issue #7 - Boy Falls From The Sky
The S&M-themed R-18+ Hero and a teacher at U.A. While she's passionate about both of her jobs, her devotion to staying in-character can rub her co-workers the wrong way. Her Quirk, "Somnambulist", lets her emit a sleep-inducing fragrance from her body.
- Bunny-Ears Lawyer: As devoted as she is to staying in-character while on the job, she's a fantastic teacher and Hero.
- Double Entendre: Keeping in with her theme, a good portion of what comes out of her mouth is this. All Might considers it a wonder that she hasn't been hit with a sexual harassment lawsuit yet.Midnight: These boys are certainly showing their stuff. If we whip them into shape, they'll become amazing in
Midnight: Come on, Ectoplasm, can't a girl crack a joke? [shrugs] Still, I'm curious. What the heck are they feeding kids nowadays for bodies and stamina like that? Because their parents are doing several things right! [collective groaning]
- Dressed Like a Dominatrix: Despite her heroic profession, she carries around a whip and struts around in a white bodysuit with thigh-high stockings and heels and carries a whip as a weapon.
- Hot for Student: Played for Laughs, but she's impressed by the "stamina" of various examinees, including Izuku and Bakugou, and believes that they'll be amazing once they're whipped into shape.
- Meaningful Name: Her real name contains the kanji for "fragrance" and "sleep", while her Hero name has a double meaning: both "midnight" as in bedtime as well her moonlighting as a Hero who caters to an adult crowd.
- Ms. Fanservice: Just look at her.
- Rapunzel Hair: Her hair goes down to her waist.
- Superhero Sobriquets: "R-18+ Heroine".
Shouta Aizawa - Eraserhead
Debut: Issue #7 - Boy Falls From The Sky
The Underground Erasing Hero and homeroom teacher of Class 1-A. While he may be generally apathetic and lazy about things that do not interest him, he has an eye for talent and ingenuity while having zero patience for any student that doesnt take U.A seriously. His Quirk, "Erasure", allows him to nullify others' control over their Quirks just by looking at them. Blinking dispels the effect of his Quirk and using it gives him dry eye.
- Brutal Honesty: Instead of letting the students believe his threat to expel the student in last place was a ruse, he outright tells them he would have expelled Mineta and even all of them if they didnt show they had potential.
- Celebrity Is Overrated: Dislikes the attention of the media, believing that it gets in the way of his job as a hero. This results in him being very obscure to the general population. He also doesnt sponsor many products, and the only one he does in order to make money is a powerful coffee brand.
- Cloth Fu: His scarf isnt just a fashion statement. Its a support item he uses to tie unruly students like Bakugou and Villains up.
- Cruel to Be Kind: His way of teaching is that it's better to be mean and unfair to the students to help prepare them for the future of dealing with natural disasters and villains.
- The Eeyore: He's a killjoy who constantly drops the cold reality of a situation and pops bubbles of naivete wherever he sees it.
- Heroic RRoD: He suffers from dry eye while using his Quirk because he has to stare at his opponent for so long.
- I Lied: Subverted. Aizawa tells his students that he was not joking about expelling the last student if they didnt meet his standards.
- Jerk with a Heart of Gold: While Aizawa is generally unpleasant to be around with his apathy and no-nonsense behavior towards heroism, he does take his job seriously and tells Mineta that he does have the potential to become a Hero due to how he used his Quirk in a unique way.
- Lazy Bum: Refuses to leave his sleeping bag unless absolutely necessary and insists on crawling to class instead of getting out and walking. Its a joke amongst Japans Heroes that if he hadnt become a Hero, Aizawa wouldve never left home.
- Odd Friendship: He and Yamada are best friends even though their personalities are complete opposites. They've known each other since they attended U.A. themselves as students.
- Paper-Thin Disguise: He rarely seems to take off his costume, consisting of a dark, long-sleeved shirt, pants, his scarf, and goggles. But he's so obscure that he just looks like a disheveled man with a big scarf so long as he's not wearing his goggles. Even Izuku, a hardcore Hero nerd, fails to recognize him at first.
- Power Nullifier: His Quirk effectively nullifies another person's Quirk, as long as it's an emitter or transformation Quirk and not a permanently active mutation Quirk. However, because Izukus powers are not from a Quirk, Aizawas ability has no effect on him. In fact, using his Quirk on Izuku felt like opening his eyes in a pool.
- Red Eyes, Take Warning: His eyes glow red and his hair stands on end when he's using his Quirk.
- Red Oni, Blue Oni: The dour and depressing blue to Present Mic's loud and lively red.
- Seriously Scruffy: His appearance is always disheveled and he's almost always deadly serious.
- Sink-or-Swim Mentor: He has incredibly high standards for what makes a Hero, including the ability to grow and adapt one's Quirk to numerous situations. Failing to meet any of his standards will result in immediate expulsion.
- Stern Teacher: He's by and far away the most stern teacher at U.A., to the point of expelling entire classes should they not meet his standards.
Hizashi Yamada - Present Mic
Debut: Issue #7: Boy Falls From the Sky
The "Voice Hero" and an English teacher at U.A. High School. He's well-known for his loud, exuberant personality and runs a weekly radio show. His Quirk, "Voice", lets him amplify the volume of his voice to ear-splitting levels.
- Anime Hair: His hair manages to be three times longer than his head and sticks up backward like some sort of reverse pompadour.
- Big Word Shout: Thanks to his Quirk, he shouts of "YEAAAAAAAAAAAH!" can be used as a weapon.
- Cool Shades: Is always seen wearing gold-tinted shades while in costume.
- Dumbass DJ: He seems to be treated like this by his co-workers, who simply can't keep up with his energy.
- Gratuitous English: While it's not visible in the text due to being written in English, his dialogue is peppered with English words like "YEAH!" when compared to the Japanese-speaking characters.
- Large Ham: He has No Indoor Voice and always tries to bring life to any occasion with his dramatic gesturing and shouting, even in serious situations like proctoring an exam. Unfortunately for him, his efforts aren't always appreciated by his co-workers or students.
- Make Me Wanna Shout: He can use his Quirk amplify the loudness of his voice to disorient others. He's had it from the moment he was born, rupturing the eardrums of his parents and the doctors with his cries. The speakers on the front of his costume let him direct it so he isn't a hazard to his allies or innocents.
- Odd Friendship: He and Aizawa are best friends even though their personalities are complete opposites. They've known each other since they attended U.A. themselves as students.
- Red Oni, Blue Oni: He's the loud, lively red to Aizawa's dour and depressing blue.
- Superhero Sobriquet: "Voice Hero".
- Mean Character, Nice Actor: His character for his cooking shows is a lot ruder and more curse-happy than the one who asks Izuku and his friends how they are enjoying their meals. Lunch Rush also provides food to victims of natural disasters.
- No Celebrities Were Harmed: The mention that he curses at professional chefs in his show makes him similar to Gordon Ramsay.
- Supreme Chef: He has studied how various cultures cook rice in order to create the best possible recipe for it. His rice is so good that Uraraka goes in-depth praising it.
