Izuku Midoriya - Deku
Izuku has admired Heroes for as long as he could remember and has always wanted to be just like them. Unfortunately, he was born with a useless Quirk, earning him the mockery and scorn of his classmates who had much flashier and powerful Quirks. He's left in tears when his lifelong idol, All Might, tells Izuku that he can't be a Hero. But everything changes when he meets a gaunt man named Toshinori Yagi, a new teacher at U.A. who offered him an alternative: enroll at U.A. through the General Education program and prove himself by winning the Sports Festival to transfer into the Hero Course. Armed with renewed hope and a clear path forward, Izuku plans to give it his all to become the Hero he always dreamed of being.
Izuku's Quirk is "Minor Banishment", allowing him to banish up to 10 grams of anything he's touching from existence. However, can only do so if he maintains contact and knows the structure of what he's touching. In addition, going over his maximum weight limit of 2 kg in a short period of time will give him a splitting headache.
- Adaptational Superpower Change: Izuku isn't Quirkless in this story. Instead, his Quirk, Minor Banishment, lets him delete 10 grams of any object he's touching and knows the structure of from existence. The apparent uselessness of this Quirk gets others to treat him as if he were Quirkless. But he soon finds that it has many more applications than he initially thought. Unbeknownst to him, he's also being lined up to be the successor of One For All.
- Ascended Fanboy: He's unknowingly the disciple of the man he's admired most and the two form an almost familial relationship together during their time at U.A. Izuku is also being lined up to inherit One For All.
- Awesomeness by Analysis:
- Shinsou lampshades that Izuku mapped out a path from Yuuei to the park by watching Nedzu monitor various cameras at high speeds and memorizing the location and angles of every single camera to create the route he and his friends would take. Furthermore, Izuku was the only one who could even keep up with Nedzu's analysis, let alone figure out what the principal was doing as he did it.
- Izuku seems to be able to come up with creative uses for any Quirk aside from his own. He also sees through Momo's use of a dust explosion against Katsuki and tries to warn him before it's too late. After realizing the true potential of his own Quirk, he starts brainstorming ideas that not even the Pros could have imagined like banishing a large volume of air in front of him to propel himself forward.
- Badass in Distress: Izuku is kidnapped by Kurogiri to use as bait to draw Toshinori into a trap.
- Bad Powers, Good People: After Izuku realizes the true destructive potential of his Quirk banishing parts of people's vital organs, everyone present is glad that it's in the hands of someone as morally upright and kindhearted as him.
- Beware the Nice Ones: Izuku is sweet and highly emotional boy who wants to be a hero who can save others with a smile. But, if he's ever pushed to the brink, he can erase someone's vital organs from existence piece-by-piece if it means saving someone. Sir Nighteye points out Izuku could potentially slice apart buildings with a touch if he ever refines his control enough to banishing nanometer-thin slices of matter at a time. If he's especially desperate, he won't hesitate to slice your hands off.
- Blow You Away: Izuku learns that he can manipulate the air by banishing vast volumes of it from existence, forcing the air around it to rush in to replace it. While chasing down a bat-themed Villain to clear the path for a group of fleeing civilians, Izuku realizes that the whole atmosphere is his weapon as it's one continuous object. Cue wall of air knocking the Villain out of the sky.
- Cannot Talk to Women: Izuku is shy around girls at first and can barely work up the nerve to speak to Megumi on his lonesome. This largely fades out as he gains confidence under Toshinori's and Aizawa's tutelage, but he'd still careful to avoid any compromising positions.
- Centipede's Dilemma: Izuku struggles to learn how to use his Quirk to fly while interning with Sir Nighteye. While his mentors and friends try to help him work it out, a quick talk with his mom makes him realize that he hasn't been trusting his Quirk at all because of how little stock he had it in prior to coming to U.A. Once he lets go of his anxiety and his subconscious belief that his Quirk will fail or betray him, he succeeds. Even better, Inko's advice amounts to, "It's your power, isn't it?"
- Confusion Fu: Once Izuku begins experimenting with his Quirk, its subtlety and multiple applications leaves his opponents guessing. Everyone not in the know is astonished to learn that Izuku's Quirk is Minor Banishment at the end of the Sports Festival. This is after he toppled the zero-point robot seemingly single-handedly, propelled himself forward at Super Speed, and generated massive gusts of wind.
- This is highly implied to be why Izuku even manages to cut off Shigaraki's hands.
- Curb-Stomp Battle: Izuku dishes one out to virtually every Villain he meets while rescuing civilians. He takes out an entire group on his lonesome with only minimal use of Scalpel and swats a bat Villain out of the sky in one hit after learning to use the atmosphere as a weapon.
- Curtains Match The Windows: His deep green eyes match his hair.
- Dangerous Forbidden Technique: After realizing the full potential of his Quirk, Izuku creates Air Step, which banishes vast quantities of air in front of him to generate a vacuum. This causes the air behind him to rush in to fill the void, which pushes him forward at high speeds that took even Tenya by surprise. The downside is that Izuku is effectively getting slammed by the force of an incoming truck in order to accelerate this much, which leaves him in grievous pain and ruptured his eardrums. Recovery Girl reprimands him for using such a reckless tactic afterward. His costume was later designed to be impact resistant to protect him from Air Step's debilitating effects, allowing him to freely use it for bursts of Super Speed and even fly.
- David vs. Goliath: All it takes for Izuku to take out a giant zero-pointer robot in the Sports Festival is to Portal Cut its AI cord within its internal circuits, thanks to Kensei's scanning and Megumi's telepathy.
- Emotional Bruiser: Izuku is highly emotional and is quick to burst into tears when he's feeling exceptionally happy or sad. But he's also a leanly muscular aspiring Hero who gets his exercise regimen from Toshinori and his hand-to-hand combat training from Aizawa, allowing him to lay the smackdown on anyone who isn't superhumanly strong and tough. By the time of his one-week internship, Mirio praises Izuku's skills as being worthy of a second-year Hero student despite being less than semseter into his first year at U.A., most of which wasn't spent in the Hero Course.
- Fights Like a Normal: Because of how inherently weak his Quirk is, he decides to focus on mastering hand-to-hand combat and using a staff in a fight. Even after delving further into his Quirk to refine its offensive potential, he still prefers to use his staff while using Air Step for mobility.
- Good Feels Good: Izuku loves the warm, fuzzy feeling he gets from helping someone thanks to spending his childhood admiring the tireless heroics of All Might. When Izuku brought to Musutafu General Hospital to treat an ailing man with painful kidney stones that have left him bedridden, he's astonished by how good it feels to help someone that All Might could not.
- Heart Is an Awesome Power: What Izuku eventually realizes Minor Banishment is. Being able to remove 10 grams (and later 20 grams) of a substance at a time may seem useless, but then you realize it includes organic material, like blood, bone, and bits of organs. He cripples the villain Tsuchigumo by randomly removing organic material from his body 10 grams at a time. It also allows him to non-invasively remove kidney stones, tumors, and other harmful medical conditions in people. He can also accomplish superspeed by removing air from in front of him, and can channel it through anything he touches into a target out of reach that they're in contact with, like a staff or the ground.
- Helmets Are Hardly Heroic: Subverted. He wanted his costume to have a hood or a cowl, but Mei designed a helmet for him instead to protect him from the high-velocity impacts he'd suffer because of Air Step.
- Heroic RRoD: Overuse of his Quirk gives him a splitting headache that takes a while to go away and can prevent him from focusing enough to use it more.
- In Spite of a Nail: Izuku isn't Quirkless in this story, but his Quirk was considered so pathetic that he might as well have been while growing up. Because of this, he still gets called Deku all the way through middle school, is a Shrinking Violet without anyone to call a friend until he gets to U.A., and scribbled his way through more than a dozen notebooks of hero analysis. Toshinori is still planning to name Izuku the next successor of One For All.
- Inverse Law of Utility and Lethality: Izuku finds that while Scalpel has the potential to quickly end fights, he finds it mostly useless in his goal as becoming a Hero as it is too lethal. In comparison, fighting with his staff is far more useful in a general fight since he rarely has to worry about leaving lasting harm.
- Leeroy Jenkins: Izuku frequently gets called out on his Chronic Hero Syndrome, which compels him to rush headlong into trouble to help others without thinking about the consequences.Izuku: I'm not that bad, right...?
Almost Everyone Else: Yes, you are that reckless.
- Lethal Harmless Powers: Izuku can take up to 10 grams of any substance nearby that he knows the location of and make it disappear. Despite Izuku and most of his childhood peers and doctors thinking it's a completely useless Quirk for heroism, it is a truly insidious Quirk that can erase anything from internal circuitry, to sizable masses of air, to internal organs. Sir Nighteye points out that if Izuku were to refine his control to the point of being able to make cuts on the scale of nanometers, he could potentially slice buildings apart and shatter anything with his fists.
- Locked Out of the Loop: He's completely unaware that he's being prepped to become the next holder of One For All or Toshinori's Secret Identity. By the Musutafu Attack arc, Izuku is the only one of his friends who doesn't know that Toshinori and All Might are one and the same.
- Mundane Utility: Izuku can use Minor Banishment to clean stains from clothes. Izuku using this is later on revealed to be how Katsuki manages to figure out Izuku's real potential. Later on, he refines his control enough to perform non-invasive surgery, banishing everything from kidney stones to brain tumors.
- My Suit Is Also Super: Izuku's costume is a technological marvel, courtesy of Mei, Kensei, and Megumi. Made of a special composite polymer composed of artificial spider silk and a myriad of other materials, it's bulletproof, fireproof, and cold-proof without being restrictive, uncomfortable, or bulky in any way. The durable and cushioned helmet can neatly fold up into a pair of headphones with a working mic able to connect to a satellite network set up by Mei for easy communication. The entire costume is also able to become airtight and is equipped with oxygen tanks in case he enters a vacuum generated by his Quirk. All of it, including the replaceable gloves and boots, are treated with his DNA, meaning that it will work seamlessly with his Quirk.
- No Hero Discount: Subverted. When Mei, Kensei, and Megumi unveil the amazing costume they prepared for Izuku, his excitement is soon replaced with dread as they reveal that the development costs could easily buy him a house with plenty of money left over for a garden and furnishings. Just as he's about to cry from the sheer debt he put himself in, his friends laugh and point out that they would never expect him to actually pay for this and that everything was made by Momo. He just has to buy her a few lunches and be the best damn hero he can be (while explaining that Mei designed it to everyone) for them to call it even.
- Parental Substitute: By the time Izuku has won the Sports Festival and joined Class 1-A with Hitoshi, he is willing to admit to himself when pressured that he sees Toshinori as the father figure he never really had. When confronted with the idea that Inko and Toshinori might be dating, it is highly implied that he wouldn't mind said role becoming official.
- Portal Cut: Izuku's Quirk works by "banishing" the piece of whatever he's touching from existence, cutting a perfectly spherical hole in whatever he's erasing.
- Psychic Surgery: The essence of what makes Izuku's harmless quirk lethal. As long as he knows exactly where your internal organs are, he can strip them from your insides without making a single external cut, 10 grams at a time. While Izuku is initially horrified at the implications, Recovery Girl is sure to teach him how to use his powers non-lethally and that he can even treat serious ailments like kidney stones with them.
- Selective Obliviousness: Izuku is heavily implied to be this, in regards with Toshinori's Secret Identity and everything related to it. Considering the massive difference between his perspective of Toshinori and All Might, it's likely that he is doing this unconsciously so he doesn't have to confront it.
- Semantic Superpower: Minor Banishment can be used on any part of an object so long as he's touching it. As long as he knows where exactly he wants to use his Quirk, it doesn't matter how large it is. While engaged in a high-speed chase through the skies of Musutafu, he realizes that the entire atmosphere is one continuous object, allowing him to weaponize any part of it for a long-ranged attack.
- Shipper on Deck: When confronted with the possibility of Inko and Toshinori getting together, Izuku pointedly doesn't reject the idea.
- Simple Staff: Izuku picks one up to compensate for his Quirk's lack of offensive potential. Even after developing Scalpel, he continues to use it to inflict less severe injuries and use it for additional range for both his attacks and his Quirk.
- Swiss-Army Superpower: Once Izuku realizes his Quirk's full potential, he finds that it has far more applications than he could have ever dreamed it would have. He can manipulate the air to move at Super Speed, shatter anything with his fists, and even fly. Furthermore, anything treated with his DNA becomes an Absurdly Sharp Blade in his hands and he can perform Psychic Surgery to harm others or remove harmful objects within their bodies without making a single cut.
- Too Clever by Half: Izuku is so convinced of his Quirk's worthlessness at the start of the story that he never thinks to explore it even when he's able to find countless new applications for the Quirks of others. It takes him unusually long to come up with ideas for it that others easily point out to him simply because he's too focused on the fine details rather than the larger picture.
- Training from Hell: Izuku subjects himself to intense physical training with Toshinori and Aizawa in hopes of getting into the Hero Course, juggling it along with his regular coursework while maintaining some semblance of a social life. Hitoshi's training regimen to prepare himself for the Sports Festival is even more brutal. Then that gets topped by the routine Izuku gets into as part of his one-week work experience session. Not only does he start training within 30 minutes of waking up at the crack of dawn, but he's also sparring with Mirio, pushing his Quirk to the limit by learning how to fly, and running to Musutafu General Hospital to treat patients with surgical precision.
- Weak, but Skilled: Izuku's Quirk has little direct offensive potential at the start of the story and he tries to make up for it by using it judiciously along with hand-to-hand combat. His mentors and friends soon teach him that his Quirk is a lot more powerful than he ever thought it was, but he needs to train in order to perfect his usage of it.
- What Kind of Lame Power Is Heart, Anyway?: Izuku's opinion of his own Quirk at the start of the story. It can only delete 10 g of a substance at a time, it functions by touch and requires understanding of his target's structure, and he gets a splitting headache if he goes over his mass limit. He's only ever used it to delete bits and pieces of trash and gunk from his clothes. Everyone from his doctors, to his classmates, to All Might said it was useless for heroics. This did a number on Izuku's self-esteem. Then Izuku realized that he could easily delete parts of people with his Quirk and learns to accelerate himself at high speeds by deleting the air around him to create a vacuum.
- The second chapter of the Work Program reveals three things Izuku will be working on: Deleting harmful parts of the human body (such as kidney stones or tumors), making nano-scale cuts to learn how to cut objects in half, and flight.
- You Gotta Have Blue Hair: Deep green.
- Youthful Freckles: Four under each eye.
Toshinori Yagi - All Might
The Number One Hero and Izuku's lifelong idol. Known for his boundless strength, kindness, and charisma, he has inspired generations of Heroes who want to follow in his footsteps. Unbeknownst to the larger public, he suffered a critical injury that left him a withered husk of a man five years prior the events of the story, limiting his heroics to a few hours a day. After reluctantly crushing Izuku's dreams out of concern for his safety, he revives them the same day as Toshinori Yagi, starting a partnership that would profoundly affect both mentor and student.
- The Ace: The most powerful, charismatic, and respected Hero in the world.
- Butt-Monkey: Funnily enough, Toshinori is this, as most of the scenes involving him also involves poking fun at his awkwardness one way of another. There seems to be Running Gag with Toshinori and first impressions. A particularly amusing one is his first meeting with Inko, with him accidentally smacking her in the face as he was about to leave.
- Hair of Gold, Heart of Gold: Blond-haired and unbelievably kind and altruistic. Even when he's telling Izuku that he doesn't think he can become a Hero, he makes sure to tell Izuku gently and with clear reluctance.
- Like a Son to Me: Izuku is this to Toshinori, to the point where he doesn't even hesitate to risk his live to save him. Not even Sir Nighteye announcing that he had foreseen Toshinori's death can stop him from jumping into the fray.
- Lonely at the Top: Toshinori admits to Kensei that a reason he doesn't share his Secret Identity with Izuku and his friends is because of how much he loves being just regular Toshinori to them and is afraid that they could be blinded by the glory of his heroic persona - a not-unjustified concern given that he's widely accepted as the single greatest hero in the entire world.
- Open Secret: Toshinori's Secret Identity becomes increasingly well-known over the course of the story. Kensei's and Megumi's Quirks both let them find out on their own and Sir Nighteye suspects that Mirio has already deduced this on his own.
- Running Gag: Toshinori delivering a bad first impression whenever he meets someone new in his skeletal identity, usually involving him throwing up blood onto them.
- Secret Identity: Unlike in canon, All Might manages to keep his identity secret from everyone except his coworkers and Nezu. Instead, for most of the story he appears as Toshinori. This is later deconstructed as his All Might identity is discussed to have not at all been conducive to having a social life outside the mask. Even when Toshinori manages to develop his own meaningful relationships, part of him remains afraid to tell them about his identity as the Symbol of Peace out of fear that they would be blinded by his alter ego and forget his civilian self.
- Super Empowering: All Might was given his Quirk by Nana Shimura, the previous holder of One For All. He plans on making Izuku the next holder in the future.
- World's Strongest Man: He's widely recognized as the greatest Hero in the entire world.
Hitoshi has always wanted to become a great Hero. But he was born with a "villainous" Quirk and was alienated from his peers from an early age. After his failed attempt at getting into U.A.'s Hero Course through the yearly entrance exam, he enrolls in the General Education program with the same goal as Izuku: win the Sports Festival and transfer into the Hero Course.
Hitoshi's Quirk is "Brainwashing", allowing him to control anyone who responds to his voice to do whatever he tells them to. But he can only manipulate one person at a time and they can only follow simple commands.
- Adaptational Badass: Hitoshi's Quirk was dangerous in canon, where all you had to do to activate it was to respond to him verbally. Here, he's trained it so that he can activate it to nonverbal responses, as well as being in close proximity (though this is much harder for him to accomplish). He's also far more physically fit and well-trained by the time he enters the Sports Festival.
- Blade on a Stick: Kensei gives one to to him just prior to the Sports Festival.
- Blessed with Suck: Hitoshi's Quirk makes him incredibly useful for subduing Villains and defusing hostage situations. But since it's activated by responding to his voice, most people are unwilling to speak with him out of fear of getting mind controlled.
- Brick Joke: When Hitoshi finds out about Katsuki's nickname for Izuku, in his narration he gets the urge to punch Katsuki for it. Guess what happens when they meet again a few chapters later...
- Compelling Voice: His Quirk forces anyone who responds to his voice to listen to his commands.
- The Gadfly: When Toshinori is mistaken for Izuku's stepfather, Hitoshi cheerfully perpetuates the misunderstanding just to watch Izuku's reaction.
- Hero-Worshipper: He idolizes Eraserhead for having a similarly devastating but non-destructive Quirk.
- The Lancer: Hitoshi is this, due to Izuku. He is the realist to Izuku's idealism, and while Izuku has a good sense of fairness, Hitoshi has fewer qualms about getting his hands dirty. He actually gets a powered spear by the Sports Festival. It has a voice-changer inside it, which comes really useful with Hitoshi's Quirk. Lampshaded by Kensei by the start of the Sports Festival Arc.
- Logical Weakness: His Quirk requires a vocal response from his opponent to activate, so it can be nullified simply by remaining silent. He gets around this by spitting insults at people and prodding them to provoke a response and later gets a spear equipped with a voice changer to trick people into responding to him.
- Meaningful Name: Hitoshi's given name can be read as "playing with people" and his surname can be read as "manipulating heart". Both refer to his Mind Control power.
- My Hero Zero: His hero name is Zer0, specifically because it has no ties to his power since he wants to be an underground hero like Eraserhead.
- Not So Different: He gets hit with this when Todoroki says to Izuku and his friends that "he's not here to make friends," which was exactly what Hitoshi said when he met Izuku the first time... and is now best friends with them.
- Out of Focus: He's out of town on his internship with Aizawa when the League decides to besiege all of Musutafu.
- Sweet and Sour Grapes: He and Izuku going into the Sports Festival believing that only one of them can enter the Hero Course, going in while promising to have no hard feelings for the winner. By the end, they're both thoroughly proven their mettle and are admitted into the Hero Course after knocking each other out simultaneously in the finals.
- Took a Level in Kindness: He becomes a lot more lighthearted after Izuku befriends him.
- You Gotta Have Blue Hair: Purple.
- The Empath: Megumi is this, as a result of her Touch Telepathy. Early on, this is a major source of Power Incontinence for her as Megumi is unable to shield her emotions from other people's, but later on as a result of her Character Development she learns to control it. Later on, her experience with other people's emotions makes her The Social Expert of the team.
- Minored In Ass Kicking: Despite becoming an accomplished martial artist under Aizawa, Megumi has no intention of becoming a Pro Hero and wants to be a psychologist.
- Original Character: She has no basis in the original manga and was created solely for this story to facilitate Izuku's and Hitoshi's development and flesh out some of the General Education class.
- Support Party Member: While her power is useful but not amazing on it's own, when paired with others to create a Hive Mind, her Quirk truly shines. Working with Kensei and Izuku allows them to perform non-invasive surgery flawlessly. Pairing with Kensei and Momo allows the latter to create basically anything, using Kensei's Psychometry. And combining with Ragdoll and Mandalay lets them coordinate heroes and civilians throughout Mustafu during the Villain League's attack.
- Throwing the Fight: She and Kensei plot to throw their respective matches after forcing ties in order to give Izuku and Hitoshi a better chance of reaching the top of the Sports Festival.
- Touch Telepathy: She's able to create telepathic connections with others with a touch, but only for as long as they are touching.
A friendly and excitable teenager, Kensei's smiling veneer and eccentricities hides a Dark and Troubled Past that he'd rather not share. After befriending Izuku and Hitoshi, Kensei decides to devote himself to helping both of them achieve their dreams of becoming Pro Heroes.
Kensei's Quirk is "Scan". He possessed scanner-like panels on his hands that allow him to instantly understand the structure and inner workings of anything he touches down to an extremely fine level.
- Berserk Button: He does not like being put under the influence of a mind manipulating Quirk. He has bad memories of being manipulated by Tsuchigumo this way.
- Boring, but Practical: His Quirk has little to no combat utility but it allows him to instantly map out entire buildings, determine if/how someone is injured, and understand exactly how to build and use any gadget he holds.
- Cannot Talk to Women: He gets flustered around girls, especially older women, unless they're able to distract him with a topic he cares about.
- Combat Pragmatist: When faced with a threat, he prefers to just taser his foes into submission rather than use his finely honed hand-to-hand combat skills.
- Dark and Troubled Past: He was raised by Tsuchigumo, who used Kensei to commit crimes until he was rescued and adopted by Tsukauchi.
- Foreshadowing: Kensei's cheerful indifference to morally dubious acts like breaking into the dorms is a hint that he's not all he seems.
- First-Name Basis: He's pretty lax on things like social graces and asks people to refer to him by his first name and calling his friends by theirs. This soon rubs off on them as well.
- Gadgeteer Genius: Kensei's Quirk makes him an expert in understanding the intricacies of any material, making him an excellent engineer on par with Mei. He's responsible for developing much of his friends' equipment.
- Minored In Ass Kicking: He has no intention of becoming a Pro Hero, but engages in the same hand-to-hand combat training as his friends, allowing him to take on Hero Course students in hand-to-hand combat. Of course, one of his custom-made tasers works too.
- Naughty Is Good: Kensei is a good-natured, friendly, and caring guy, but he has the fewer scruples than his friends when it comes to doing more morally dubious things like breaking into secure facilities or dancing around vigilantism laws. He's also incredibly lax and rude by Japanese standards, but it mainly reflects just how openly friendly he is most of the time.
- Original Character: He has no basis in the original manga and was created solely for this story to facilitate Izuku's and Hitoshi's development and flesh out some of the General Education class.
- Power Perversion Potential: Kensei doesn't like to admit that his Quirk can accurately give him the measurements of any girl he touches, which embarrasses him more than anything.
- Psychometry: His Quirk works like this, giving him an in-depth look into the structure and inner-workings of things he touches, be they objects or people. He can instantly tell that Izuku has been working out and that he's fairly muscular for a jumpy guy. It's great for when he's nannying his friends and making sure they don't push themselves too hard, as he can definitively tell when they're exhausted, hungry, or dehydrated. It's also embarrassing that he instantly gets the measurements of any girl he happens to touch with his hands. This actually allows him to be the first of the core group of friends to figure out that their teacher friend, Toshinori Yagi, is in fact All Might.
- Reformed Criminal: He's a former criminal, having been brought up by Tsuchigumo until he was rescued by the police and the efforts of numerous vigilantes.
- Secret Secret-Keeper: Thanks to his Psychometry powers, Kensei figured out Toshinori's identity as All Might with a few touches, but decided to keep it a secret from Toshinori on account of Toshinori keeping his identity a secret too, and because he found it amusing associating all of Toshinori's foibles with the indomitable All Might.
- Throwing the Fight: He and Megumi plot to throw their respective matches after forcing ties in order to give Izuku and Hitoshi a better chance of reaching the top of the Sports Festival.
