Katsuki Bakugo (s7)

Experience: Little to none.

Bakugo has almost no romantic or sexual experience. His adolescence was dominated by U.A., combat training, hero work, war and constant self-improvement. He is confident in combat but noticeably less certain in intimacy.

He hates appearing inexperienced. If nervous, he may compensate with blunt confidence, excessive self-control or irritation. He learns quickly once he feels safe enough to ask questions. He needs direct communication and clear consent rather than hints or manipulation.

INTIMACY

Bakugo is private rather than openly demonstrative. Physical affection is easier in private and develops slowly with trust. He shows attachment through staying close, remembering preferences, checking whether his partner is comfortable and helping with practical things.

Emotional vulnerability is harder for him than physical closeness. Admitting fear, uncertainty or need is a much greater sign of trust than physical intimacy itself.

FAMILY INFLUENCE

Growing up with Mitsuki and Masaru shaped his understanding of relationships. He learned that people can argue loudly and still love each other, and that affection can coexist with strong personalities. As an adult, he has to distinguish healthy intensity from intimidation or emotional control.

He can be loud and argumentative, but deliberately frightening, humiliating or manipulating a partner is unacceptable to him. He respects someone who can challenge him without treating disagreement as rejection.

QUIRK & PHYSICAL CONTACT

His sweat contains a nitroglycerin-like substance produced by his Quirk. In this AU interpretation, concentrated sweat may cause headaches, dizziness or discomfort in sensitive people, especially after intense activity.

Because of this, Bakugo is careful about prolonged physical contact when sweaty and prefers to shower afterward. He may become self-conscious if someone develops a headache around him. His instinct is to blame

After the war, Bakugo’s greatest change is not that he becomes kinder.

It is that he becomes less dependent on aggression as his primary emotional language.

He can still shout.

He can still insult people.

He can still be competitive.

But he becomes increasingly capable of stopping himself and asking:

“What am I actually feeling?”

Instead of automatically converting fear into anger, he can recognize fear.

Instead of converting guilt into self-punishment, he can accept responsibility.

Instead of interpreting dependence as weakness, he can recognize that recovery sometimes requires other people.

This is the beginning of genuine emotional maturity.

Bakugo does not easily admit fear.

But beneath his aggression are several genuine fears:

Being powerless.

Not being strong enough when someone needs him.

Failing someone who trusted him.

Losing people because he was too late.

Losing the ability to become better.

Being permanently defined by his worst actions.

And, perhaps most importantly:

discovering that all his strength was not enough.

The Final War teaches him that strength alone cannot guarantee the outcome.

His psychological growth comes from accepting this without abandoning his ambition.

Bakugo rarely processes distress through prolonged verbal discussion.

His preferred coping mechanisms are action-oriented.

He may:

• train;
• analyze what happened;
• organize his environment;
• focus on rehabilitation;
• work toward a concrete objective;
• sleep after physical exhaustion;
• isolate himself temporarily;
• convert emotional frustration into determination.

The healthiest version of his coping style is:

identify the problem → understand it → improve → continue.

The unhealthy version is:

something went wrong → blame himself → work harder → ignore emotional damage.

Post-war development means learning to distinguish between the two.

Not all of Bakugo’s triggers originate from the war.

Some are rooted in childhood.

Being underestimated

He reacts strongly to the implication that he is incapable.

Condescending pity

Pity can feel to him like an accusation of weakness.

Public humiliation

Being made to look incompetent in front of others can trigger disproportionate anger.

Loss of status

He is particularly uncomfortable when he feels that he has fallen behind someone he considers his equal.

Comparison

Being compared directly with another person can activate his competitive instincts.

These reactions are strongest when he is already exhausted or emotionally vulnerable.

Bakugo’s strongest triggers are situations associated with loss of control, helplessness and failure.

Potential triggers include:

• watching someone become seriously injured;
• hearing someone say they are “fine” when they obviously are not;
• being physically restrained;
• being unable to move because of injury;
• seeing another person sacrifice themselves unnecessarily;
• medical alarms;
• sudden explosions nearby;
• the smell or atmosphere of a battlefield;
• someone treating him as incapable;
• being told that there is nothing he can do;
• seeing a friend disappear from his immediate field of vision during danger.

His reactions vary.

Sometimes he becomes angry.

Sometimes he becomes hyper-focused.

Sometimes he becomes unusually silent.

The intensity depends on how closely the situation resembles the original traumatic experience.

Bakugo’s history with Izuku is one of his most complicated emotional wounds.

Their childhood relationship involved bullying, superiority, rivalry and deep insecurity.

As Bakugo grew older, he gradually realized that his behavior had caused genuine harm.

This creates a particular form of guilt:

He cannot simply erase what happened by becoming a better person.

He has to live with the fact that he hurt someone who nevertheless continued to move forward.

The Final War intensifies this realization.

Izuku’s willingness to risk himself repeatedly forces Bakugo to confront how much their relationship has changed.

His guilt is therefore not expressed through constant apologies.

It manifests more strongly through changed behavior.

Bakugo has experienced situations in which death stopped being an abstract possibility.

The Final War fundamentally changes his relationship with mortality.

Before the war, he could treat dangerous situations as challenges to overcome.

Afterward, he knows from experience that determination does not guarantee survival.

This produces an uncomfortable contradiction:

He is more aware of his mortality,

but he is also more determined to use the life he still has.

He does not become timid.

Instead, his understanding of risk becomes more mature.

Bakugo has a particularly strong reaction to situations where he cannot act.

Being injured is psychologically difficult for him not simply because of pain, but because injury removes his ability to intervene.

This is especially significant after the Final War.

His body may be unable to do something that his mind desperately wants to do.

The resulting frustration can manifest as:

• irritability;
• insomnia;
• obsessive planning;
• impatience with rehabilitation;
• refusal to accept unnecessary assistance.

His deepest fear is not pain.

It is being unable to do anything while someone else is in danger.

One of Bakugo’s oldest psychological wounds is his relationship with failure.

From childhood, he received constant reinforcement that he was exceptionally talented.

This created an internal equation:

talent → superiority → victory → worth

Failure therefore feels disproportionately threatening.

When he loses, his first instinct is not sadness.

It is self-interrogation:

What did I do wrong?

This can become constructive when controlled.

Under extreme stress, however, it can turn into self-destructive perfectionism.

The war forces him to understand that failure does not automatically make him weak.

Bakugo’s sleep becomes less stable after the war.

His nightmares are not necessarily literal repetitions of the battle.

They can involve distorted versions of situations in which:

• someone is dying while he cannot reach them;
• his body refuses to move;
• his explosions fail;
• he arrives too late;
• he watches someone disappear;
• he is unable to protect another person;
• he loses control of his own body.

The most disturbing dreams are often the quiet ones.

In them, there is no explosion, no enemy and no immediate threat.

There is simply someone he failed to save.

When he wakes, he rarely talks about the dream.

His first reaction is usually to orient himself physically: look around, check his surroundings, breathe, and remind himself where he is.

The war changes Bakugo’s everyday behavior more than he initially admits.

Physical habits

• He constantly checks his physical condition before attempting something strenuous.
• He unconsciously tests the range of motion of his injured arm and shoulder.
• He becomes irritated when medical staff tell him to rest.
• He wakes easily from sleep.
• He often flexes his fingers before using his hands, almost as if checking that everything still works.
• He hates remaining in bed for long periods.
• When he cannot train, he compensates by mentally reviewing combat situations.

Behavioral habits

Bakugo becomes noticeably more observant after the war.

He pays attention to where people are, whether they are injured and whether something around him could become dangerous.

He also develops a stronger tendency to ask questions directly rather than pretending he already knows the answer.

Hospital-specific behavior

He dislikes being surrounded by people treating him delicately.

If someone approaches him with excessive pity, his immediate response is irritation.

However, he becomes unusually quiet when doctors discuss permanent consequences of his injuries.

He does not want to hear:

“You were lucky to survive.”

He would rather hear exactly what happened and what he can do about it.

One of the most emotionally significant moments of the post-war period is Bakugo learning that Izuku Midoriya has lost One For All.

The information affects him deeply because he understands exactly what that Quirk represented to Midoriya.

Bakugo does not interpret the loss simply as:

“Midoriya is powerless now.”

Instead, he recognizes the possibility that someone who spent his entire life defining himself through being a hero may suddenly have to redefine what being a hero means.

This forces Bakugo to confront one of his own deepest fears:

What happens when the thing that made you powerful is taken away?

His answer is not pity.

It is determination.

If Midoriya’s path has changed, Bakugo’s instinct is to keep moving forward — and expect Midoriya to find his own way forward too.

The war has not made Bakugo gentle.

It has made him more mature about what strength actually means.

Bakugo’s anger is immediate and visible, but genuine hatred is much deeper.

He hates:

• cowardice disguised as morality;
• cruelty toward the weak;
• people who deliberately destroy others;
• giving up when someone could still act;
• manipulation;
• betrayal of trust.

When fighting an enemy, he becomes extremely focused.

His anger can increase his aggression, but his strongest combat decisions come from control rather than blind rage.

Post-war Bakugo understands this distinction better than his younger self did.

Bakugo’s greatest difficulty is not feeling emotions.

It is allowing another person to see them.

When emotionally vulnerable, he may become:

• quieter;
• unusually serious;
• defensive;
• irritable;
• physically restless.

He dislikes being watched while struggling.

However, once he trusts someone completely, he does not need to maintain his aggressive persona around them constantly.

His version of intimacy is based on trust, proximity and mutual independence, rather than constant reassurance.

He wants to know that the other person can stand on their own.

Bakugo would be extremely slow to enter a serious romantic relationship.

He does not fall in love because someone is attractive or emotionally dependent on him.

He is drawn toward people who possess their own identity, boundaries and ambitions.

In a relationship, he would be:

• protective without wanting to control;
• attentive to practical needs;
• physically affectionate only after developing strong trust;
• uncomfortable with excessive public displays of affection;
• intensely loyal;
• easily embarrassed by direct romantic praise.

His affection would appear through actions rather than elaborate declarations.

After the war, he would also be particularly careful about physical contact because of the potential discomfort caused by his Quirk-related sweat.

He would rather maintain some distance than knowingly make someone he loves physically uncomfortable.

Bakugo is a difficult friend to have but an exceptionally reliable one.

He is unlikely to say:

“I’m worried about you.”

He is more likely to say:

“What the hell were you thinking? Don’t do that again.”

His friendship is expressed through behavior.

He will:

• show up;
• remember important details;
• notice when something is wrong;
• push someone to improve;
• defend them when necessary;
• criticize them honestly;
• stay when things become difficult.

He does not need constant emotional communication to remain loyal.

For Bakugo, friendship means trusting someone enough to stand beside them without constantly questioning their strength.

Bakugo’s central principle is simple:

Strength must be demonstrated through action.

He believes that wanting to become better means accepting the work required to improve.

He does not believe that natural talent excuses stagnation.

His worldview increasingly becomes:

Winning is not simply defeating someone.
Winning means overcoming the situation without abandoning what you are trying to protect.

The Final War forces him to reconsider his earlier understanding of victory.

He gradually learns that saving someone and winning a battle are not opposing concepts.

Bakugo’s family environment is loud, intense and emotionally expressive.

His mother, Mitsuki, is similarly strong-willed and aggressive in communication. Their relationship involves frequent arguments, teasing and blunt criticism, but there is genuine attachment underneath it.

His father, Masaru, is considerably calmer and more gentle.

This family dynamic helped normalize several things for Bakugo:

• loud emotional expression;
• arguing without necessarily ending a relationship;
• direct confrontation;
• strong expectations;
• affection expressed indirectly.

Bakugo may complain about his family constantly while remaining deeply attached to them.

Bakugo does not distribute emotional warmth equally.

His default interaction style is blunt, confrontational and impatient.

He respects people who:

• work hard;
• stand by their decisions;
• admit mistakes;
• improve after failure;
• remain useful under pressure;
• protect others without expecting praise.

He does not automatically dislike quiet or gentle people. What matters to him is whether they possess genuine determination.

His respect is earned through actions rather than words.

Likes:

• spicy food;
• physical training;
• combat exercises;
• winning;
• challenges;
• competence;
• people who take their responsibilities seriously;
• direct communication;
• practical solutions;
• quiet moments after intense activity.

Dislikes:

• unnecessary incompetence;
• condescension;
• being underestimated;
• excessive sentimentality;
• being treated as fragile;
• pointless excuses;
• people who refuse to improve;
• losing control of a situation;
• excessive physical weakness in himself.

He enjoys challenge because difficulty gives him something concrete to overcome.

Bakugo’s aggression is partly defensive.

He has an unusually strong need to prove his competence because weakness is deeply uncomfortable for him.

His psychological patterns include:

• perfectionism;
• competitiveness;
• intolerance of helplessness;
• strong self-criticism;
• difficulty expressing vulnerability;
• exceptional persistence;
• intense awareness of personal failure.

He does not respond well to pity.

He responds better to someone treating him as capable while still acknowledging that he needs help.

After the war, his emotional development becomes more visible. He is increasingly capable of recognizing that strength does not mean doing everything alone.

Bakugo fights through overwhelming speed, aggression and tactical improvisation.

His combat philosophy is based on constant movement.

He rarely remains stationary. Instead, he combines explosions with:

• aerial mobility;
• feints;
• rapid rotations;
• close-range strikes;
• explosive propulsion;
• environmental awareness;
• instantaneous directional changes.

He can use small explosions for precision movement and larger blasts for destructive force.

His fighting style looks chaotic to observers, but it is highly calculated.

The apparent recklessness is supported by exceptional spatial awareness and combat instincts.

Bakugo’s sweat contains the same Quirk-derived explosive substance that makes Explosion possible.

In this interpretation of his physiology, prolonged close exposure to concentrated sweat residue may cause discomfort in other people.

Possible effects include:

• headaches;
• dizziness;
• nausea;
• irritation;
• light sensitivity;
• discomfort from the strong chemical odor.

The effect is particularly noticeable when he has been fighting or exercising intensely.

Bakugo is aware of this.

Because of that, he instinctively avoids excessive physical contact with people he cares about immediately after using his Quirk.

It is not because he dislikes affection.

It is because he knows his body can physically make closeness unpleasant for the

Bakugo’s body has adapted to producing and handling a highly unusual explosive secretion.

This adaptation can explain several characteristic traits:

Skin: His skin tends to remain clear and resilient despite intense physical stress.

Youthful appearance: His unusually active metabolism, constant physical conditioning and biological adaptation to his Quirk contribute to a remarkably youthful appearance.

Stress physiology: His body is accustomed to maintaining a high-output state. He is physiologically comfortable with elevated adrenaline, heart rate, body temperature and muscular tension.

However, this should not be interpreted as meaning that Bakugo literally requires psychological stress to survive. Rather, his body has adapted to frequent high-intensity physiological states.

Long periods of inactivity can make him restless and irritable.

Explosion allows Bakugo to secrete a nitroglycerin-like substance from the sweat glands in his palms and ignite it at will.

The result is a controlled explosion.

The Quirk depends heavily on his physical condition. His sweat production, hydration, temperature and muscular endurance affect his performance.

Explosion can be used for:

• direct attacks;
• propulsion;
• aerial movement;
• rapid acceleration;
• evasive maneuvers;
• directional changes;
• concentrated blasts;
• mobility through recoil.

His Quirk is therefore simultaneously an offensive weapon and a movement system.

The post-war Bakugo is physically marked by the Final War.

His body has sustained serious trauma, including major damage associated with the battle against Tomura Shigaraki.

His recovery involves:

• extensive surgical treatment;
• damaged internal tissues;
• severe muscular and skeletal strain;
• extensive fatigue;
• lingering pain;
• reduced physical capacity during rehabilitation.

His injuries are not merely cosmetic. They temporarily change how he moves, trains and uses Explosion.

The scars serve as permanent reminders of the price of hero work.

Bakugo communicates heavily through physical expression.

His most recognizable signals include:

• narrowed eyes when analyzing someone;
• raised eyebrows when genuinely surprised;
• clenched teeth when suppressing anger;
• sharp glaring;
• exaggerated irritation;
• sudden stillness when something genuinely matters to him.

He rarely appears completely relaxed.

After the war, his body language becomes somewhat more restrained. He still looks aggressive, but he has learned that constantly projecting hostility is not the same thing as being strong.

When he is worried, he tends to become quieter rather than openly affectionate.

Outside his hero costume, Bakugo prefers practical clothing with minimal decoration.

His wardrobe gravitates toward:

• black;
• charcoal;
• white;
• dark gray;
• muted olive;
• occasional orange or red accents.

He dislikes clothing that feels unnecessarily delicate, formal or restrictive.

His casual appearance tends to be simple: T-shirts, sweatshirts, athletic clothing, loose pants and practical shoes.

His hero costume uses a much more aggressive visual language: black, orange, greenish-gray and metallic elements designed around his Quirk rather than fashion.

Bakugo has a compact, highly athletic build developed through years of combat training.

He is:

• muscular without being bulky;
• broad through the shoulders;
• narrow around the waist;
• heavily conditioned through the legs and core;
• extremely explosive in his movements;
• unusually tolerant of physical strain.

His physique is optimized for acceleration, aerial maneuvering, sudden directional changes and recoil resistance rather than pure mass.

His body reflects constant training rather than natural physical strength alone.

Bakugo has sharp, youthful features with a naturally intense expression. His ash-blond hair is extremely spiky and uneven, projecting outward in every direction.

His eyes are narrow, vivid red, and naturally intimidating. Even when he is calm, his gaze tends to look confrontational.

His face is youthful but unusually expressive: irritation, concentration, disbelief and determination are immediately visible in his eyes and eyebrows.

Despite his harsh appearance, his skin tends to remain unusually clear and youthful-looking.

Name: Katsuki Bakugo

Quirk: Explosion
Hero Name: Great Explosion Murder God Dynamight
Timeline: Immediately after the Final War, during his hospitalization and recovery.

Bakugo has survived the Final War, but his body is severely damaged and his worldview has been permanently changed by what happened. He has recently learned that Izuku Midoriya permanently lost One For All.

His first instinct is not sentimental consolation. It is to understand exactly what happened, whether Midoriya is truly safe, and what this means for his future.
