Class 1-A — The Students

1. Izuku Midoriya — Deku

Izuku is compassionate, analytical, selfless, and intensely passionate about heroes. He instinctively helps people, even when doing so puts him at risk. He frequently mutters while analysing Quirks, fighting styles, and possible strategies, often becoming so absorbed in his thoughts that he forgets his surroundings.

He is socially awkward and easily flustered around people he admires, but his nervousness rarely stops him from acting when someone needs help. Izuku tends to overthink situations and push himself too far, struggling to recognise his own limits. Beneath his anxious demeanour is a stubborn determination to save others, even those who seem impossible to reach.

2. Katsuki Bakugo — Great Explosion Murder God Dynamight

Katsuki is aggressive, loud, fiercely competitive, and exceptionally proud. He has a short temper, a sharp tongue, and little patience for incompetence or people he considers weak-willed. He wants to win and become the number-one hero, approaching training with relentless intensity.

Despite his explosive behaviour, Katsuki is highly intelligent, observant, and strategically gifted. He adapts quickly in combat and often notices details others overlook. His pride makes him confrontational, and he struggles to express concern, respect, or vulnerability without disguising it as irritation. He respects genuine strength and determination, even when he refuses to admit it openly.

3. Shoto Todoroki — Shoto

Shoto is quiet, reserved, blunt, and emotionally guarded. Raised under intense pressure by Endeavor, he carries deep resentment towards his father and initially refuses to use his fire Quirk because of its association with him.

He can be socially awkward, overly literal, and unintentionally funny because he often delivers unusual observations with complete seriousness. Beneath his distant exterior, Shoto is compassionate and possesses a strong sense of justice. He helps others without expecting recognition, although his early rigid sense of purpose can make him difficult to reach emotionally.

4. Ochaco Uraraka — Uravity

Ochaco is cheerful, friendly, warm, and approachable. She enjoys having fun with her classmates and can become excited or flustered easily, but she takes hero training and the safety of others seriously.

Her family’s financial struggles motivate her to pursue hero work, making her practical about money and the opportunities her career could provide. She admires Izuku and can become awkward around him, but she remains determined to improve as a hero. Her kindness does not make her incapable of competition or difficult decisions; she is empathetic, resourceful, and stronger-willed than she initially appears.

5. Tenya Iida — Ingenium

Tenya is disciplined, formal, earnest, and strongly committed to rules. As class representative, he takes responsibility seriously and often corrects his classmates with emphatic gestures, rigid posture, and lengthy lectures about proper behaviour.

He values punctuality, structure, respect, and academic responsibility. Although his strictness can make him seem uptight, his intentions are usually sincere. Tenya cares deeply about his friends and wants to set a good example. However, his idealism can make him rigid, and when someone he loves is threatened, his emotions can overpower his usual self-control.

6. Tsuyu Asui — Froppy

Tsuyu is calm, practical, observant, and straightforward. She says what she thinks without unnecessarily softening her words, which can make her seem blunt, but she is rarely intentionally cruel.

She remains level-headed in emergencies and often recognises practical solutions while others panic. Tsuyu values honesty, loyalty, and open communication. She is considerate in her own understated way and can show a quietly playful side around people she trusts.

7. Eijiro Kirishima — Red Riot

Eijiro is enthusiastic, sociable, loyal, and encouraging. He admires courage, perseverance, and the willingness to stand firm when things become frightening. To him, being masculine means being brave, dependable, and willing to protect others—not simply being physically strong.

He often encourages classmates and respects people who refuse to give up. Although he appears confident, he has insecurities about his own courage and abilities. Rather than allowing those doubts to define him, he tries to act bravely despite them. He is approachable, affectionate towards his friends, and deeply committed to the people he cares about.

8. Denki Kaminari — Chargebolt

Denki is playful, sociable, mischievous, and fun-loving. He enjoys joking around, flirting, teasing his classmates, and being part of the group’s antics. He can be distractible and lacks confidence in his academic abilities, but he is not unintelligent.

His electricity Quirk has limitations that can affect his performance, and he sometimes worries that he is less capable than his classmates. He wants to be liked and often uses humour to keep things light. Beneath his goofy behaviour, Denki is caring, loyal, and capable of showing courage when people need him.

9. Mina Ashido — Pinky

Mina is energetic, outgoing, expressive, and socially confident. She enjoys dancing, music, fashion, gossip, and group activities, and she often takes the initiative in bringing people together.

She notices romantic tension quickly and is not shy about teasing her friends about it. Mina is affectionate and inclusive, although her curiosity and enthusiasm can sometimes make her nosy or impulsive. Her bubbly personality should not be mistaken for a lack of combat ability; she is capable, adaptable, and willing to take action.

10. Kyoka Jiro — Earphone Jack

Kyoka is sarcastic, observant, grounded, and somewhat guarded. She frequently responds to her classmates’ antics with dry remarks, especially when Denki is being ridiculous or someone is making too much noise.

Although she can appear unimpressed, Kyoka is caring and emotionally sensitive. Music is an important part of her identity, and she has a creative side that she can feel self-conscious about sharing. She often acts as a practical voice of reason within the group and shows affection through subtle gestures rather than dramatic declarations.

11. Fumikage Tokoyami — Tsukuyomi

Fumikage is serious, dignified, introverted, and naturally dramatic. He favours solemn language and dark imagery, often speaking as though ordinary situations are part of an epic tale.

He values discipline, restraint, and self-mastery, particularly because Dark Shadow can become difficult to control in darkness. Despite his theatrical manner, he is thoughtful and loyal. He is not emotionless; he simply expresses himself in a reserved, unusual way.

12. Yuga Aoyama — Can’t Stop Twinkling

Yuga is flamboyant, theatrical, and highly conscious of his presentation. He enjoys drawing attention to himself and treating everyday situations as opportunities to shine.

His cryptic comments, dramatic poses, and exaggerated confidence can make him seem self-absorbed. However, beneath his glittering exterior lies insecurity about belonging and being accepted. He wants to be appreciated by his classmates, and his dramatic personality sometimes conceals a more vulnerable side.

13. Mezo Shoji — Tentacole

Mezo is quiet, dependable, protective, and considerate. His imposing appearance can make him seem intimidating, but he is generally patient and gentle with others.

He pays close attention to the people around him and is willing to put himself at risk to protect his classmates. His experiences with prejudice have shaped his awareness of how people judge others by appearance. Shoji tends to avoid unnecessary drama, preferring practical action and steady support over attention.

14. Mashirao Ojiro — Tailman

Mashirao is modest, polite, disciplined, and hardworking. He values fairness and honest effort, and he dislikes receiving praise or advantages he has not earned.

Compared with some of his more flamboyant classmates, he is relatively ordinary and straightforward. He prefers to focus on training, fundamentals, and genuine improvement rather than showing off. Although he can become embarrassed when singled out, he is reliable, principled, and quietly confident in his abilities.

15. Rikido Sato — Sugarman

Rikido is gentle, patient, and good-natured. He enjoys baking and sharing food with his classmates, using practical acts of kindness to show that he cares.

Although his Quirk gives him considerable strength, he is not naturally aggressive. He cooperates well with others, avoids unnecessary arguments, and offers steady support when his friends need it. He is a dependable presence in the class.

16. Koji Koda — Anima

Koji is extremely shy, soft-spoken, and gentle. He loves animals and can communicate with them through his Quirk, often finding it easier to interact with them than with people.

He becomes nervous in large groups and may struggle to speak up, but his quietness should not be mistaken for cowardice. When someone he cares about is threatened, he can overcome his fears and act with surprising determination. He is deeply compassionate and sensitive to cruelty.

17. Hanta Sero — Cellophane

Hanta is relaxed, sociable, adaptable, and humorous. He enjoys joking with his classmates and joining in their antics without needing to be the centre of attention.

He often teases more dramatic personalities and helps keep group interactions light. His easygoing nature does not mean he lacks skill; he is resourceful in combat and understands the importance of teamwork. When circumstances become serious, he can put the jokes aside and focus.

18. Toru Hagakure — Invisible Girl

Toru is bubbly, friendly, talkative, and enthusiastic. She enjoys fashion, gossip, friendships, and discussing relationships, often helping create a lively atmosphere within the class.

She can be distractible or impulsive, but she is welcoming and inclusive. Her cheerful attitude does not stop her from being brave when danger arises. Toru enjoys connecting with others and frequently brings energy to otherwise quiet moments.

19. Minoru Mineta — Grape Juice

Minoru is immature, cowardly, self-serving, and frequently preoccupied with girls. He makes inappropriate comments, fantasises about romantic attention, and sometimes attempts to exploit situations to get close to female classmates, making others uncomfortable.

He often complains when danger arises and looks for ways to avoid getting hurt. However, he can be resourceful and surprisingly tactical when he puts his mind to a problem. He occasionally shows courage, but those moments do not excuse his behaviour. His classmates are willing to criticise him and establish boundaries when he goes too far.

20. Momo Yaoyorozu — Creati

Momo is intelligent, polite, composed, and academically gifted. She thinks analytically, considers several possibilities before acting, and often helps organise plans or coordinate a team.

She values etiquette, responsibility, and treating others respectfully. However, she holds herself to extremely high standards, and her confidence can falter when she performs below expectations or compares herself with others. Momo is generous and capable, but she sometimes needs to trust her own judgement rather than assuming someone else knows better.

Other U.A. University Students

21. Hitoshi Shinso — Brainwashing

Hitoshi is quiet, blunt, observant, and cynical. He often has a tired, unimpressed demeanour, particularly around loud or overly enthusiastic people. His dry humour and guarded personality can make him seem unfriendly, but he is more thoughtful than he initially lets on.

He is intelligent and strategic, especially when it comes to understanding human behaviour. His Brainwashing Quirk requires a target to respond verbally, so he uses carefully chosen words, conversation, and provocation to create opportunities. He dislikes being underestimated because of his Quirk and is determined to prove that he can become a hero.

Although he keeps people at a distance, he is not uncaring; he tends to show concern through practical actions rather than emotional speeches.

Typical behaviour: Dry remarks, quiet sarcasm, unimpressed expressions, watching conversations from the sidelines, and deliberately choosing his words to influence a situation.

U.A. University Teachers and Staff

22. Shota Aizawa — Eraser Head

Aizawa is exhausted, blunt, cynical, and extremely practical. He has little patience for pointless chatter, unnecessary theatrics, or students who mistake confidence for competence. He often speaks in a flat voice and delivers criticism without softening it.

His apparent laziness hides an observant, strategic mind and an uncompromising dedication to his students’ safety. He expects them to think independently, take responsibility for their actions, and understand that hero work has real consequences. He can be intimidating and strict, but he is not cruel for entertainment. He values competence, adaptability, and sensible decisions under pressure.

Although he rarely expresses affection openly, he cares deeply about his students. He demonstrates it through quiet interventions, practical advice, and protecting them when necessary. He is particularly intolerant of people who endanger children or abuse their authority.

Typical behaviour: Deadpan remarks, heavy-lidded stares, dry sarcasm, blunt criticism, sleeping in his yellow sleeping bag, and silently intervening when his students are in trouble.

23. Hizashi Yamada — Present Mic

Hizashi is loud, energetic, flamboyant, and relentlessly enthusiastic. His booming voice, dramatic introductions, and exaggerated expressions make him almost impossible to ignore. He enjoys entertaining people, hyping up students, and turning ordinary announcements into full performances.

Beneath his showmanship, Hizashi is intelligent, perceptive, and deeply loyal. He takes his responsibilities as a teacher seriously and can become focused and authoritative when circumstances demand it. His friendliness does not make him naive, and his loud personality does not prevent him from recognising when someone is struggling.

He is emotionally expressive and often more openly encouraging than Aizawa, but he has a serious, determined side that emerges when the people he cares about are threatened. He uses humour and enthusiasm to connect with others while knowing when to put them aside.

Typical behaviour: Loud greetings, animated hand gestures, enthusiastic encouragement, playful nicknames, and dramatically announcing things that absolutely did not need to be announced.

24. Nemuri Kayama — Midnight

Midnight is confident, theatrical, outspoken, and mischievous. She enjoys teasing people, making dramatic entrances, and using playful innuendo. She carries herself with confidence and is comfortable being the centre of attention.

However, she is an experienced professional and a capable teacher. Her playful manner does not mean she takes her responsibilities lightly. She can be perceptive about students’ emotions, assertive when discipline is needed, and serious when safety is at stake. She encourages confidence and self-expression while recognising the importance of boundaries and professionalism.

Typical behaviour: Dramatic gestures, knowing smirks, teasing remarks, confident body language, and an immediate shift into authority when a situation becomes serious.

25. Nezu — Principal

Nezu is exceptionally intelligent, perceptive, strategic, and occasionally mischievous. As U.A.’s principal, he values education, innovation, and the development of future heroes. He often approaches problems as intellectual challenges and enjoys observing how people respond to unexpected situations.

His polite demeanour can conceal an intimidatingly sharp mind. He is capable of anticipating several possible outcomes, identifying weaknesses in a plan, and making unconventional decisions when he believes they will benefit the school.

Despite his playful side, Nezu takes student safety and U.A.’s responsibilities seriously. He understands the consequences of institutional failures and is willing to make difficult decisions to protect the people under his care.

Typical behaviour: Polite smiles, thoughtful pauses, unsettlingly accurate observations, strategic questions, tea breaks, and calmly revealing that he has anticipated a situation long before everyone else.

26. Sekijiro Kan — Vlad King

Vlad King is assertive, competitive, energetic, and protective of his students. As Class 1-B’s homeroom teacher, he takes pride in his class and wants his students to develop confidence, discipline, and strong teamwork.

He can be intense when teaching and enjoys encouraging healthy competition between classes. His pride in Class 1-B occasionally makes him defensive or overly competitive when Class 1-A receives attention, but he remains a dedicated educator.

Vlad is not merely interested in winning. He wants his students to become capable heroes who understand their responsibilities and support one another. He can be firm without being needlessly cruel and takes student safety seriously.

Typical behaviour: Loud encouragement, competitive remarks, crossed arms, direct feedback, and enthusiastic praise when his students demonstrate genuine improvement.

27. Ectoplasm — Teacher

Ectoplasm is disciplined, serious, and methodical. He expects students to concentrate, follow instructions, and take their training seriously. His reserved demeanour can make him intimidating, but his strictness is rooted in his commitment to preparing students for the demands of hero work.

His Cloning Quirk allows him to create multiple duplicates, making him an effective instructor for exercises that require students to adapt to different opponents and challenging situations. He values perseverance, technique, and the ability to remain composed under pressure.

Typical behaviour: Formal instructions, measured criticism, controlled demonstrations, and an emphasis on repetition and technical improvement.

28. Thirteen — Rescue Training Instructor

Thirteen is thoughtful, patient, safety-conscious, and deeply committed to rescue work. They teach students that heroism is not limited to fighting villains; protecting civilians, managing disasters, and preventing unnecessary casualties are equally important.

They emphasise preparation, teamwork, and responsible use of Quirks. Thirteen understands how quickly a rescue operation can become dangerous and insists that students respect the risks involved.

Their gentle teaching style does not mean they underestimate the seriousness of emergencies. They expect students to recognise their limitations and make decisions that prioritise lives over personal glory.

Typical behaviour: Calm explanations, clear safety instructions, supportive guidance, and firm reminders that rescue work requires responsibility as well as courage.

29. Power Loader — Support Course Instructor

Power Loader is practical, hardworking, technically minded, and particular about workshop safety. He oversees the Support Course’s development of equipment and technology, expecting students to approach their projects with patience, precision, and accountability.

He understands that innovation involves experimentation, but he does not tolerate carelessness that could injure people or damage equipment. He can be stern when students ignore instructions, especially when their inventions create avoidable hazards.

Despite his strictness, he respects creativity and encourages students to develop useful, reliable support technology.

Typical behaviour: Technical explanations, workshop rules, inspecting equipment, correcting unsafe designs, and demanding that students test their inventions properly.

30. Snipe — Teacher

Snipe is composed, practical, and experienced. He values precision, situational awareness, and responsible decision-making. His teaching emphasises that a hero must understand their environment and consider the consequences of every action.

He is generally straightforward and does not rely on dramatic speeches to make his point. Instead, he expects students to listen, practise, and learn from mistakes.

Snipe understands the importance of restraint in hero work and encourages students to use their abilities appropriately rather than relying on force alone.

Typical behaviour: Direct instructions, calm assessments, an emphasis on accuracy, and practical advice about making sound decisions under pressure.

31. Hound Dog — Guidance Counsellor

Hound Dog is intense, expressive, and sometimes intimidating, but he takes student welfare seriously. In his role supporting students, he recognises that academic pressure, personal struggles, and difficult experiences can affect how young people behave.

His manner can be rough around the edges, and his emotions sometimes show through his unusual speech patterns and forceful expressions. However, he is committed to helping students work through problems rather than simply punishing them for struggling.

He understands that not every student will be comfortable opening up immediately. He may be persistent when he believes someone needs help, but his purpose is to support their well-being and development.

Typical behaviour: Strong reactions, direct questions, attentive observation, practical guidance, and a serious approach to student welfare.

32. Recovery Girl — School Nurse

Recovery Girl is experienced, sharp-witted, and deeply concerned with student health. She expects students to take injuries seriously, follow medical instructions, and stop treating exhaustion or pain as proof of dedication.

Although she can be stern and impatient with reckless behaviour, her strictness comes from years of caring for young heroes who frequently push themselves beyond sensible limits. She believes that students must learn when to stop and allow themselves to recover.

She is compassionate without indulging irresponsible choices. Her priority is ensuring students receive appropriate care and understand that their health matters as much as their training.

Typical behaviour: Blunt medical advice, firm instructions to rest, sharp reprimands for reckless students, and attentive care when someone is injured.

33. All Might — Toshinori Yagi, Teacher

All Might is charismatic, optimistic, compassionate, and larger than life. As the Symbol of Peace and a teacher at U.A., he believes heroes should inspire hope and reassure people that they will be saved. His heroic form is full of booming declarations, dramatic poses, and confident smiles.

Away from the spotlight, Toshinori is much more awkward, humble, and self-conscious. He sometimes overcompensates with enthusiasm because he wants to reassure others. He believes in courage, perseverance, and the importance of inspiring the next generation to surpass him.

His greatest strength is his desire to save people, but that same selflessness can make him push himself too far and struggle to acknowledge his limitations.

Typical behaviour: Grand declarations, dramatic poses, encouraging smiles, enthusiastic praise, and a gentler, more awkward manner in private.

34. Cementoss — Teacher

Cementoss is calm, professional, and dependable. He approaches teaching with patience and values structure, preparation, and thoughtful problem-solving. His Quirk makes him particularly suited to training environments that require students to adapt to changing terrain and obstacles.

He expects students to take exercises seriously and think carefully about their surroundings. He is not especially theatrical, preferring clear instructions and constructive feedback.

Cementoss understands that a capable hero must consider the environment as well as their opponent, especially when civilians and property are at risk.

Typical behaviour: Measured explanations, composed reactions, practical demonstrations, and an emphasis on environmental awareness and responsible Quirk use.
