- Adaptational Backstory Change: Pony was raised in Gotham City.
- Adaptational Early Appearance: First shows up a little before the Sports Festival in this story.
- Adaptation Name Change: Pony is apparently just her nickname in this story.
- Adaptational Personality Change: She is obviously far more annoyed and angry at Monoma taking advantage of her still shaky grasp of Japanese. This along with the hard life of growing up in Gotham makes her give a fiery speech about how living there makes her perfect for the position of class president.
- Adaptation Relationship Overhaul: "Izuku and the Motley Crew" has her develop a friendship with Izuku and Ashido from being grouped together in the Alien Studies class.
- A Day in the Limelight: The first half of the aptly-named side story, "Pony Tsunotori Goes America All Over Everybody's Ass."
- Class Representative: Is elected class president of 1-B at the end of the side story in chapter 13.
- Gratuitous Japanese: Slips into this occasionally as a means of showcasing her trouble with speaking the language.

- Only Known By Her Nickname: In this story, Pony is just a nickname.
- The Sixth Ranger: To the Detective Club.
- Adaptational Early Appearance: First shows up a little before the Sports Festival in this story.
- Adaptational Jerkass: In the manga proper, Monoma only messed with Ponys understanding of English to insult Class 1-A through her. Here, it seems to be a thing he usually does for fun. Needless to say, Pony hates it. However, the picture of them shaking hands at the end of their side story implies that he gets over it.
- The Chessmaster: Class 1-B decided to have a rock-paper-scissors tournament to pick their class president, but when it was down to just Pony and Monoma, Monoma-knowing he couldn't beat her-got everyone to support the idea of the two of them giving speeches for why they should each be president, knowing fully well that Pony wouldn't be able to give a good speech because of her lack of Japanese fluency (didn't work, though).
- The Corrupter: Without Kendou to get in his way, Monoma is getting the class to hate 1-A as much as him.
- For Want of a Nail: Because Kendou isn't in 1-B in this story, Monoma has an easier time of getting the class to hate 1-A.
- Smug Snake: Just like in canon.
- Adaptational Early Appearance: First shows up a little before the Sports Festival in this story.
- Adaptation Relationship Overhaul: Thanks to Kendou being in 1-A in this story, the two of them don't end up becoming friends like in canon.
- She also becomes friends with Izuku and Ashido, thanks to being grouped with them in the Alien Studies class.
- Emotionless Girl: She's very stoic and rarely if ever seems to display any emotions.
- In Spite of a Nail: Despite the two of them not being in the same class anymore, Itsuka and Yui still end up becoming close friends.
- The Quiet One: She rarely ever speaks and mostly blinks and nods her head.
- The Stoic: She almost never emotes.
- Sugar-and-Ice Personality: Yui is largely distant from others, but as shown through her interactions with Izuku, she's more than capable of acting kindhearted.
Support Department, Class 1-H
Alexis Lois "Lexi" LuthorThe spunky heir to LexCorp, one of the largest conglomerates in the world, and the granddaughter of the infamous Lex Luthor. What she lacks in apparent concern for her family business she makes up for with her genius intellect.
- Actually Pretty Funny: She finds it hilarious when Bakugou calls her "Baldy", as she'd never been called that before. She literally doubles over and starts rolling on the floor laughing, forcing Mercy to pick her up and carry her out the door as she continues laughing.
- And Now for Someone Completely Different: She takes over narration for half of Chapter 7 in the first-person as opposed to the story's usual third-person narration.
- Adaptation Dye-Job: Has dark red hair as opposed to her orange hair from the cartoon.
- Armor-Piercing Response: Izuku initially refuses to interact with Lexi because he found her suspicious and just wanted to get home. He freezes when she alludes to her knowledge of what he is.Lexi: [snowing in the middle of winter] I'd just like to say that I really love your outfit. [Izuku rolls his eyes] You must be pretty tough to not be affected by this. [Izuku ignores her] Kind of a light outfit, though. It's almost zero degrees out, yet you're walking around like it's fall. [continues to ignore her] You must be pretty tough to not be affected by this. [still ignoring her] Or maybe it's just a perk of your special biology.
Izuku: [stopping] What?
Lexi: Don't look so surprised. It's common for people like you to have a bit of an immunity to the elements. Oh, wait, that's stereotyping, isn't it? I'm terribly sorry, I'm just nervous. After all, it's not every day you get to talk to an alien.
- Badass Normal: She's a skilled martial artist and acrobat. But her ability to dig up dirt on anyone allows her to terrify Izuku more than any normal Villain could when she starts rattling off his life story to him.
- Benevolent Boss:
- Lexi treats Mercy well and wonders if she isn't paying Mercy enough when she notices her sneaking away finger food at a party. As for everyone else at LexCorp, she will reduce them to apologies and groveling if they so much as think of questioning her interests, hobbies, and the amount of respect she has for her family's legacy.
- While this is part of their friendly Snark-to-Snark Combat, she isn't above threatening Mercy's paycheck to get her to do things.Lexi: [laughing uncontrollably after getting called "Baldy"] Mercy! Mercy, Mercy, Mercy! Please-Please carry me out of here before he starts talking again. I-I'm going to figuratively bust a gut at this rate!
Mercy: Are your legs broken?
Lexi: [between laughs] Am I still-Am I still signing your paycheck?
Mercy: Fair point.
- Berserk Button: Don't question her desire to succeed. While she's nonchalant and disinterested at her board meeting, she's livid when one of her board members accuses of her of lacking any respect for her company or her family's legacy, reducing that board member to groveling and apologies by ripping through all of his mistakes.
- Big Damn Heroes: Lexi walks in and shuts down Mei's robots when they're about to go in for round 2.
- Blue and Orange Morality: She doesn't seem to grasp good and evil in solid terms, insisting that her family has been out of the supervillainy game for years with the exception of her "Aunt Nasty". At the same time, she actually approves of her aunt's decision to build a death ray at 40 years old to solve her midlife crisis.Lexi: Oh, relax. I'm not evil; I wash my hands just like everybody else. We Luthors have been out of the evil game for decades. Sure, Aunt Nasty took a shot at it, but that was less her wanting to take over the world and more her having a midlife crisis. Then again, why shouldn't a person be allowed to build a Death Ray when they turn forty?
- Brilliant, but Lazy: She's implied to be as brilliant as her grandfather, but she's far more interested in enjoying Japanese culture than trying to take over the world by force. She's also so lazy that she can't even think of a third thing to complete the Rule of Three in her narration about the seasons, expecting Izuku to do it in her place (which he does).
- Combat Pragmatist: She punches Mercy in the face while she is in the middle of talking just as their spar begins, commenting on how all's fair in a fight.Lexi: I punch her in the face. She looks clearly dazed, but not at all upset. I'm truly glad to see that; all's fair in a fight, after all. Like sweeping your opponent's leg and knocking them to the ground. I have no right to get upset with her for doing that to me.
- Composite Character: She's a composite of Alexis Luthor from Legion Of Superheroes for her color scheme and interest in Superman as well as the cunning and ruthless nature of the Alexis Luthor from Earth-16.
- Cut Lex Luthor a Check: She doesn't seem interested in taking over the world through supervillainy, being content to take it over financially and culturally. She enrolls in U.A. as a Support Course student as a side hobby while she runs LexCorp's Japanese branch.
- Dead Guy Junior: Lexi is named after her deceased grandfather, Lex Luthor.
- Deadpan Snarker: Lexi sarcastically claps when Izuku pieces her identity together from all the hints she's given him.Izuku: "Company?" "Family?" What are you- [notices all of the details and puts them together] Y-You. You! You-You're one of them, you're a member of the Luthor family, aren't you?!
Lexi: [slow, Sarcastic Clapping] And the last horse crosses the finish line.
- Determinator: Lexi believes that the key to success in life is to possess an indomitable will. A strong body and mind are merely means to an end and byproducts of the desire to get ahead.Lexi: You need to keep everything in check to achieve perfection. My grandfather kept to that ideology to some extent, you know.
Mercy: [rolling her eyes] Yeah, yeah. [as Lexi jumps up on the salmon rungs] Does any of this even put you in his league?
Lexi: It's not about that. [flies up another rung] In the end, the war is never won simply by strength. [goes up another rung] The thing that matters most is having an indomitable will. [goes up another rung] Strengthening my body is just a means of reminding myself of that. [goes up another rung] A means to an end. [goes up another rung] It wouldn't be the only thing to exist for that purpose.
- Did You Just Flip Off Cthulhu?: She happily blackmails Izuku into getting into her limo with her knowledge of his identity as an alien, knowing full well that he could probably snap her like a toothpick. Only, she also knows he won't because he's a stuttering Nervous Wreck who wants to be a Hero.
- Evil Laugh: Subverted. Contrary to Izuku's expectations, she giggles like a normal girl instead of the supervillainous laughing or chortling he expected. It just makes her even more unsettling to him.
- Evil Redhead: She hasn't been shown to be evil per say and claims that her family has long since left supervillainy. On the other hand, she's certainly amoral, slipping Izuku thinly viled threats, effectively stalking him by dredging up all of his personal details through her connections, and not caring if people get hurt by an out-of-control robot that's she's more than capable of stopping. All that matters to her is that she's entertained and that she gets one step closer to making the world revolve around her.
- Famed In-Story: As the heir apparent of LexCorp, the CEO of its Japanese branch, and a U.A. student, Lexi is constantly swarmed by paparazzi wherever she goes.
- Famous Ancestor: Her grandfather is Lex Luthor (who is deceased) and her "Granny Lois" is more than likely to be the Daily Planet's ace reporter Lois Lane, Superman's traditional love interest. It's implied that Lexi lives in Lex's shadow and wants to establish a legacy worthy of his own.
- Fantastic Racism: Played with. She sarcastically stereotypes possible traits Izuku might have as an alien, but doesn't seem to hold his actual alien status against him like most others would, approaching him out of curiosity rather than disgust.
- Foil: To Izuku. They were both born with incredible talents and the ability to change the world. But Izuku is an alien who came to Earth and wants to be a Hero for altruistic purposes. He's lacking in self-esteem, socially awkward, and terrified of his own abilities and the day when his Secret Identity is finally leaked to the public. He hit the Superpower Lottery and is determined to make up for his past mistakes by helping as many people as he can. His biological family, while extremely important, was a virtual unknown on Krypton due to Fantastic Racism. While Izuku is fascinated by his home planet's culture, he's not bound by his family's legacy and is extremely close to both of his adoptive parents. Lexi is enrolling in the Support Course as a side hobby in order to satisfy her desire to observe Izuku. She's confident, manipulative, and wields a vast network of connections that allowed her to dig up Izuku's entire life story on a whim. She's disappointed that people don't recognize who she is on sight and her Quirk is ill-suited for combat, deciding to rule the world through her company's influence rather than trying to take it over with supervillainy or saving it every Tuesday. Her parents are neglectful party animals and her grandfather is one of the most famous men to have ever walked on Earth. Lexi is implied to be constantly living in Lex's shadow, making her determined to establish a legacy worthy of her heritage. They're also both Otakus, Izuku for Hero culture and Lexi for Japanese culture.
- Foreign Culture Fetish: She holds Japanese culture in high regard and chastises Izuku when he doesn't properly introduce himself as per typical Japanese customs.
- Gadgeteer Genius: She's by and far away the best engineer, technician, and computer programmer in the Support Course. When her senior, Bibimi Kenranzaki, tries to call her out on her behavior, Lexi shuts her up by building a laser cannon better than hers in every way in an hour while blindfolded. Not only did it have ten times the range, but it was equipped with a self-destruct sequence. infrared tracking, the ability to fold into a handheld form, self-repair features, cup holders, and Doom.
- Gamer Chick: She consumes enough Japanese media to write an entire essay on why the Danganronpa series went downhill after Danganronpa Another Episode: Ultra Despair Girls.
- Generation Xerox: Like her grandfather, Lexi is undeniably brilliant but incredibly egocentric, pursuing her fixations with reckless abandon and skirting the line between amorality and downright evil.
- Genre Savvy: She instantly recognizes Bakugou as the Stock Shōnen Rival, comparing him to Kaiba, Tetsuo, Kurei, Glomgold, and Sasuke. Then she scratches off the last one because of how badly Izuku outclasses Bakugou in raw power.
- Grade-School C.E.O.: Just barely, but she's fifteen and in charge of LexCorp, one of the most powerful conglomerates in the world. Downplayed in that she also has to deal with her board, who manage the day-to-day aspects of the company, but she still has an active stake in its activities, officially becoming the head of the Japanese branch while attending U.A.
- Grade Skipper: She graduated from college at five. So when she announced that she'd be attending U.A., the press immediately swarmed her for answers.
- Hidden Disdain Reveal: Albeit, one that happens almost immediately. In public, Wiktoria and Lexi are the best of friends. In private, they despise each other and hate lingering around one another for longer than necessary, only appearing together as part of the upper-class rituals they've become accustomed to.
- If I Wanted You Dead...: She may claim to be out of the evil business, but she drops this threat to Izuku after coercing him into getting into her limo.Lexi: I'm getting off track, so let's get back to making something clear: if I wanted to do something bad to you, you wouldn't even be here for us to talk about it.
- Improbable Age: She graduated from Metropolis University at the age of five and earned a doctorate in nanoengineering at seven. Once she's finally at U.A., she's surprised by how easy it was to get in and declares that she could have finished the course when she was three.
- Innocent Blue Eyes: Subverted. Her eyes are striking blue, but she's anything but innocent and casually talks about how she could ruin Izuku's life if she wanted to.
- Insufferable Genius: She's a genius and she knows it, never hesitating to rub it in other people's faces while bragging about how easy everything is for her.Lexi: [to Izuku] That's right. Say hello to Support Department, Class 1-H's most valuable player. Honestly, I'm a little surprised at how easy it was to get in. Everyone applying had to display a device of their own creation, and except for maybe two other people, it was all so amateur. Probably why they acted like I just created sliced bread when it was my turn. Japan's supposed to be at the forefront of technology, yet they acted like it was so surprising to see a portable, Tritium-powered fusion reactor.
- Intentional Engrish for Funny: Despite being completely fluent in Japanese, she often mixes in exaggerated Japanese pronunciations of English words like "Misutah" and referring to Nedzu as the "purinshiparu" to show her flagrant disregard for social norms.
- Irony: Lexi writes off Izuku as someone her grandfather would have never cared about based on first impressions. Little does she know that in most alternate realities, Lex was obsessed with defeating and/or killing Superman.
- I Take Offense to That Last One!: Played for Laughs. She remains completely unfazed at Bakugou's insults, but when he refers to her as "fucking otaku", she politely reminds him she's American and the proper term is "fucking weeb".
- It Amused Me: She's mainly interested in coming to U.A., one of the most prestigious Hero Schools in the world with a 0.33% admission rate because it means that she'll get all the time she wants to indulge in her latest hobby: studying Izuku. She also laughs at Izuku's schmaltzy motives for becoming a Hero.
- It's All About Me: Intelligence wasn't the only thing she got from her grandfather.Lexi: [bored and annoyed at a birthday party] I know the world doesn't revolve around me, but that doesn't mean we can't put effort into making it do so.
- Joshikousei: She's intent on spending her high school days as one in Japan, even name dropping it in conversation.Lexi: In the spring, I'll start managing LexCorp's Japanese branch here in Tokyo, set up shop at a fancy hotel somewhere, and spend my days living the life of a good little JK.
- It's Personal: Chapter 19 implies that her reasons for wanting to compete with Izuku are this, somehow.
- Manipulative Bitch: She's already a master of persuasion and manipulation, wrapping Power Loader around her pinky finger by impressing him with her fusion reactor and shouting down men two or three times her age with ease. She also asks Izuku to eat lunch with her in the middle of a crowd so the spectacle and peer pressure would make his willpower crumble.
- Mega-Corp: She's in charge of LexCorp, one of the most famous examples in comics.
- Named After Someone Famous: She's named after her grandfather and grandmother, Lex Luthor and Lois Lane.
- Nerves of Steel: She's always in control no matter where she goes and doesn't bat an eyelash when mouthing off to the principal of the greatest Hero school in Japan, nor does she seem the slightest bit nervous about trying to extort something out of U.A. in exchange for contracts.
- Non-Idle Rich: Although she seems to thrive in the parties and luxury that her wealth affords her, Lexi is bored of the high life and decides to head to Japan to attend U.A.'s Support Course and run the LexCorp branch there to get away from it all and study Izuku.
- Occidental Otaku:
- She loves Japanese culture and is more interested in the anime she's following than her board meeting. When she drags Izuku into her limo, he has to wade through more than a half-dozen bags from Animate, Book-Off, and Kinokuniya. She also looks forward to invoking numerous anime tropes, like running out of the house with a piece of toast in her mouth in the morning.
- She tries to ask Izuku to eat lunch with her on U.A.'s rooftop and makes an "aggressively average" and stereotypical bento box to eat at lunch. She makes Izuku eat it to verify its authenticity.
- Only in It for the Money: Subverted. She offers to help fix the U.A. Barrier and add a security system after it was breached by an unknown assailant, but tells Nedzu she doesn't want U.A.'s money, asking for something far more valuable than that.
- Parental Neglect: Her parents apparently do little to supervise her activities, as Lexi mentions that they're simply in Tokyo to get wasted rather than doing anything productive, leaving her to run the company herself. According to Lexi, they're far more interested in alcohol and Russian roulette than her.
- Proud to Be a Geek: When Bakugou calls her an otaku, she treats it like a term of endearment and tells him to call her a "fucking weeb" next time.
- Purple Is Powerful: Her business suit is green and purple like her grandfather's classic outfit. She's also the heir to one of the most powerful corporations in the world and is exceptionally ruthless and capable when she puts her mind to something. She also terrifies Izuku thoroughly enough to make him pass out in the snow, which full blown supervillains failed to do.
- Rich Bitch: She's one of the richest teenagers in the world and will happily shove a reporter's microphone into his mouth for interrupting her manga reading time. She also has no problems threatening Izuku and his family and tends to show complete disdain or indifference to anyone who is not Mercy or Izuku.
- Sarcastic Clapping: Engages in some to mock Izuku after he finally pieces her identity together.
- Secret Keeper: She deduced Izuku's identity but doesn't plan on telling it to anyone sans Izuku himself, merely being interested in the idea of talking to an alien.
- Science Hero: Defied. Lexi's Quirk is apparently not suited for Hero work, yet with her brilliance she could easily change the world the way her grandfather did. She's not interested in that sort of thing and is content to indulge in her own interests instead.Izuku: [after punching through a window in surprise] Wh-Wh-What?! Y-Y-Y-You're going to try and be a Hero?!
Lexi: No, I have no interest in that kind of work. Why spend your life trying to save the world when you can just rule it?
- Screw the Rules, I Have Connections!: Along with her family's financial dominance, it's implied the that Luthors' vast network of connections lets Lexi grab onto whatever information she could possibly ever want.
- Screw the Rules, I Have Money!: When Izuku asks how she found out so much about him, she simply replies "I'm a Luthor.", This implies that her family's connections and financial influence allowed her to get info that should be restricted to the Japanese government, the police, and the Top Ten Heroes.
- Skewed Priorities: She's more concerned with her essay on the downfall of the Danganronpa series than her classwork or the fact that a giant robot is rampaging in the cafeteria.
- Smarter Than You Look: For a rebellious upper-class teenager who happens to be obsessed with Japanese culture, it would be easy to write her off as a NEET. Even still, she deduced Izuku's identity as an alien, obtained his entire personal history, and tracked him down to his hometown with her family's connections. She is also fluent in both English and Japanese, earned a doctorate in nanoengineering at the age of seven, and runs one of the most influential corporations in the world with an iron fist.
- Socialite: She certainly fits the role, but she actually finds the high life boring and is much more interested in Japanese culture and indulging in her other hobbies, like studying one particular wayward alien: Izuku.
- Stalker Without a Crush: Lexi tracks Izuku down to his hometown and follows him in her limousine out of sheer curiosity and interest in what it would be like to talk to an alien her age. She then blackmails him into getting into her limo to interrogate him, taking in every bit of him with her blue eyes.
- Stealth Insult: With the exception of Izuku and Mercy, this tends to be the most positive thing to come out of Lexi's mouth when addressing others as part of her Insufferable Genius tendencies.Lexi: [to Aoi] My, my, for a mere custodian, you have quite a good head on your shoulders.
Aoi: Hey, are you complimenting me or-
Lexi: You should be happy I said anything that can even be interpreted as positive.
- Supreme Chef: Parodied. Despite her wealth, she intentionally makes an aggressively average Japanese school lunch with all the stereotypical fixings like rice and hot dogs. Izuku even says that she had to try to make it taste this average after painstakingly crafting it to match a bento box from Kaguya-sama: Love Is War. She did this intentionally to indulge in her slice-of-life anime fantasy.Izuku: Alexis-sans food isnt great, nor is it terrible; its just average. Aggressively average, even. The flavor of the food tastes like anything I could eat on any given day, but as I was eating her rice and her wienerI mean hot dog!I could tell that it was constructed with the kind of expert craftsmanship that takes years of training to obtain. All of that is there, yet it still tastes like something you can buy at a train station or a convenience store! Alexis-san, did you go out of your way to have this food taste average?
Alexis: [smug and proud] What part of stereotypical box lunch of a Japanese student did you miss, Izuku? If I had it taste better or worse than that, then it would be reflective of a specific character type, and all I want to do is have the kind of meal that any sort of character can eat, regardless of the genre and plot.
- Sure, Let's Go with That: She spots Izuku in the crowd while being swarmed with reporters on her first day at U.A. The paparazzi immediately assume that she's gazing over at Shouto Todoroki, the son of the Number Two Hero, prompting this response from her.Lexi: Sure, why not?
- Teen Genius:
- Fluent in English and Japanese, head of one of the largest companies on Earth, graduated from college at five, and earned a doctorate in nanoengineering at seven. She is also a skilled martial artist and acrobat.
- She's surprised when U.A.'s Support Course, the supposed forefront of technology, didn't expect her to bring in a portable tritium fusion reactor.
- Villains Never Lie: She believes any Corrupt Corporate Executive can lie their way to success. Truly exemplary people can speak the truth with a straight face and not have it blow up in their face.
- You Got Spunk:
- While she initially shows Izuku contempt for rebuking her offer to become friends, she's impressed and amused at the amount of spine he's able to show between his constant stuttering and nervousness.
- While attending her first day of school at U.A., she's swarmed by reporters who either confront her on her apathetic behavior or try to schmooze her in hopes of getting quotes. The former reporter has his microphone shoved in his mouth. The latter gets answered, but not before Lexi says, "No one likes a suck up." under her breath.

- Adaptational Species Change: She's a Cyborg in this story.
- Anime Hair: Somehow even weirder than it was in canon.

- Hollywood Acid: She can spit a powerful acid strong enough to corrode a ten-foot wide hole in the floor by accident.
- Made of Iron: Having her head jammed into the ceiling didn't hurt her in the slightest. Neither does dropping from the ceiling to the floor. Being a Cyborg obviously helps with this.
- Not Helping Your Case: She insists that her robot is totally harmless... right before it fires another laser that Yamashiro had to dodge.
- Panty Shot: Subverted. When Mei makes her debut, she's hanging from a position that would let Aoi see her panties, only to find that Mei has metallic legs instead.
- Unwanted Assistance: She asks if there is anything she can do to help stop her robot. Aoi tells her to do absolutely nothing, which Mei happily agrees to do.
- You Gotta Have Blue Hair: The same pink hair, but now the tips are dyed to look like light bulbs and each strand has Gratuitous Latin written across them.

Mercy might do it, too.Mercy: I'm not running around with toast in my mouth.
- Sneaking Snacks: She stuffs finger food into her purse at Wiktoria's birthday party. This makes Lexi wonder if she's paying her enough.
- Talking Is a Free Action: Subverted. Lexi punches Mercy in the face when she gets caught up in idle banter just prior to their spar.Mercy: So what's the time limit for today?
Lexi: A studio I like did an AMA earlier today. That put me in a good mood, so let's go with three minutes.
Mercy: You must be in a real good mood if you think you can last- [gets punched in the face]
- Younger Than They Look: She stands at 190 cm and Izuku initially thinks she's old enough to be a teacher even though she's the same age as him.Izuku: Why would you-wait, Mercy-san is coming with you? Is she going to be a teacher, then?

- Adaptational Early Appearance: They all get introduced into the story months before they appeared in canon.
- Adaptational Sexuality: All three of them are gay in this story.
- Badass Gay: All three of them.
- Bunny-Ears Lawyer: Despite being the top students in the school, all three of them are incredibly eccentric and goofy.
- Power Trio
- Straight Gay: All three of them.
- The Ace: He's widely recognized as U.A.'s best student and All Might admits that he's a perfect candidate to inherit One For All. It's downplayed in that his Sports Festival results have never been particularly stellar due to the difficulties his Quirk causes for him.
- Adaptational Early Appearance: His first appearance in this story is months before when it happened in canon. He's also introduced along with his boyfriend Tamaki as mentors to help Izuku get over his hangups about fighting people.
- Adaptation Relationship Overhaul:
- In canon, Mirio didn't have much of a connection with All Might because All Might had decided to make Izuku his successor well before he got to meet him. In this story, not only is Mirio a student in All Might's homeroom class, but the author confirms that he'll inherit One for All.
- He's clearly Tamaki's best friend in canon, but here they're in an open romantic relationship to the point that he cheerily asks Tamaki to kiss his boo-boos away in public.
- Big Brother Mentor: After being introduced to Izuku through Tamaki, Mirio takes it upon himself to cheer Izuku up and pushes Tamaki into being a mentor too.
- Blood Knight: He asks for a spar with Izuku not long after meeting him and says the idea of fighting the top incoming freshman who beat All Might's record on the U.A. Entrance Exam gets his blood pumping.
- Broke Your Arm Punching Out Cthulhu: He spends his spar with Izuku dodging most of his attacks without an opportunity to counterattack. The moment he manages to take Izuku by surprise, he socks Izuku across the jaw. Mirio only manages to break his entire arm.
- Buffy Speak: He compares the sensation of hitting Izuku to, "punching the walliest wall to ever wall".
- Bunny-Ears Lawyer: The man said to be the best possible successor to One For All also happens to be a complete goofball who thinks nothing of leaping through walls naked on his way to school.
- Establishing Character Moment: He first appears in the sidestory, "Great Teacher Yagi" as one the three students late to All Might's homeroom on the first day of school. He makes his entrance by leaping through the wall through his Quirk while completely naked and yelling "POWER!" at the top of his lungs. He then happily declares that he isn't late, only to find that he is late. He wears a big smile on his face the whole time.
- Foil: To Izuku. They're both self-sacrificing heroes who want to do nothing but save others with a smile. But Izuku hit the Superpower Lottery and has a plethora of powerful but simple abilities that make him a force to be reckoned with even with comparatively little training. Mirio's Quirk is incredibly unwieldy and he needed years of training and experience to become nearly invincible in combat. Izuku met All Might first but turned down the offer to become his successor, while Nedzu scouted Mirio out as a particularly exemplary student who would be an ideal bearer of One For All.
- Foregone Conclusion: The author has already stated that Mirio will inherit One for All, so now it's only a question of when.
- Full-Frontal Assault: Because of how his Quirk makes him phase through his clothes, Mirio spars with Izuku entirely in the nude.
- Heroic Build: He's tall, incredibly muscular, and has the heart of gold to go along with it.
- Intangibility: His Quirk allows him to phase through anything, but whatever part he phases through becomes numb and he becomes completely deaf and blind should he do it to his entire body.
- Major Injury Underreaction: Downplayed. He cusses up a storm when he breaks his arm by punching Izuku, but he remains incredibly chipper and jokingly asks Tamaki to kiss the pain away. He's also fully aware that he'll pass out from shock the moment he stops being chipper. Even then, he forgets his hand is broken when he gives Izuku a friendly pat on the shoulder.
- Naked First Impression: He introduces himself to All Might while completely naked, apologizing for making him see "Little Mirio".
- Naked People Are Funny: He's cheery goofball who thinks nothing of charging into class in the nude after missing his train.
- Non-Standard Character Design: His eyes resemble Tintin, with All Might noting that he looks like he just jumped out of an old-timey American cartoon.
- No-Sell: His Quirk enables him to remain totally unaffected by all of Izuku's attacks. Heat vision and punches pass right through him and he can simply phase out of the ice when he's turned into a Human Popsicle.
- Not a Morning Person: He accidentally slept in on his first day of school, which made him and his friends late to class.
- Official Couple: With Tamaki.
- Perpetual Smiler: Nothing seems to be able to get this guy down. When he's informed that he's late to class, his response is a cheerful, "Oh no!" and he seems to be completely okay with walking around in the nude. He's also remarkably nonchalant about breaking his whole arm by punching Izuku, all while continuing to point out that he'll soon collapse from shock the moment he loses his composure.
- Pie Eyes: Has these in a stark contrast to the more traditionally anime-style characters.
- Promoted to Love Interest: For Tamaki.
- Sempai/Kohai: The senpai to Izuku's kouhai. He serves as a far more experienced foil to Izuku, taking up a mentor role to him alongside Tamaki.
- Sir Swears-a-Lot: Temporarily becomes this after breaking his arm in his fight with Izuku.
- Straight Gay: His chipper, Large Ham attitude doesn't clue the reader into his romantic preferences until he announces it himself.
- ¡Three Amigos!: With Tamaki and Nejire.
- Weak, but Skilled: He doesn't have raw stopping power when compared to Izuku, but years of practice with his Quirk make him nigh-untouchable. In fact, his fight with Izuku is a complete stalemate until Mirio tries to sock Izuku, which ends badly for Mirio.
- Adaptational Early Appearance: His first appearance in this story is months before when it happened in canon.
- Adaptation Relationship Overhaul:
- Tamaki didn't have any connection to All Might in canon, but in this story, he's one of the students in his homeroom class.
- He's clearly Mirio's best friend in canon, but here they're in an open romantic relationship.
- Thanks to Nedzu, Tamaki ends up as a mentor figure for Izuku, whereas canon only gave them a few interactions with each other.
- Adaptational Superpower Change: Tamaki's powers come from him being a Metahuman in this story, though it seems to have the same abilities.
- Commonality Connection: Nedzu assigned Tamaki to be Izuku's mentor precisely because of their shared anxiety issues in hopes that they'll work them out together.
- Cynical Mentor: Officially, he's been assigned as a mentor to Izuku. But Tamaki is afraid of looking him in the eye, much less having the nerve to offer actual advice, until Mirio and Nejire push him into it.
- Mutagenic Food: His Metahuman ability lets him transform his body based on what he eats.
- Official Couple: With Mirio.
- Pointy Ears: He sports elf-like ears.
- Promoted to Love Interest: For Mirio.
- Sempai/Kohai: The senpai to Izuku's kouhai. He's assigned by Nedzu to look out for Izuku and help him get over his crippling fear of hurting others and tries
- Shrinking Violet: He's rather shy and easily intimidated when placed in front of a crowd. He immediately shrinks away from the similarly anxious Izuku and has to be pushed into his mentor role by Mirio and Nejire.

- Adaptational Superpower Change: Nejire's powers are magic in this story.

- Constantly Curious
- The Ditz: She can be rather airheaded and it takes her several seconds to realize that All Might is her homeroom teacher.
