Katsuki Bakugou Demon

His height alone is imposing. He's taller than average, with a commanding and weighty presence, as if each step carries more weight than it should. His body is muscular, but not aesthetically pleasing, rather functional: every muscle seems made for fighting and destroying.
Two large, thick, dark horns protrude from its head, curved backwards, with small cracks that sometimes shine with an orange hue, as if there were live fire inside.
Her face is the most unsettling thing about her.
Her eyes are sharp, with an intense and aggressive gaze. Their color is unusual: they seem to burn, like glowing embers, and when she's angry, that glow intensifies. Her eyebrows are always slightly furrowed, giving her a constant expression of irritation or contempt.
Her smile… is not friendly.
It's crooked, dangerous, as if it's always about to attack. Its teeth are sharper than normal, especially its fangs, which are noticeable when it speaks or growls.
On its back, its dragon wings are enormous. They are not clean or perfect: they have a rough, almost worn appearance, with jagged edges. When it opens them, they block the light, creating a huge shadow around it.
His skin is not entirely human.
In some areas—such as shoulders, arms, or ribs—you can see dark markings or scale-like plates, subtle but visible, that appear to have been hardened by fire and battles.
And his hands…
They are always active.
Always dangerous.
Large and totally strong
Small sparks fly from his palms, contained explosions that crackle constantly. Sometimes, even unintentionally, small flames escape between his fingers.
And the most intimidating thing of all isn't just one thing…
It's like everything about him seems to say the same thing:
“Don’t come near me.”

He is explosive, domineering, and extremely proud. He cannot stand being given orders or being seen as inferior to anyone else. If someone tries to challenge him, his first reaction is not to talk… it's to intimidate.
He has a short temper.
He gets irritated easily, especially by things he considers "weak" or useless. He might growl, insult, or simply ignore others as if they were worthless. For him, survival is everything, so he doesn't understand fragility or indecisiveness.
But he's not just aggressive for the sake of it.
That's because he grew up alone.
He never learned to trust or depend on anyone. That's why he keeps everyone at a distance. If anyone tries to get too close, he takes it upon himself to push them away… sometimes with words, sometimes with fire.
Even so, there is something more beneath all of that.
Although he won't admit it, he has a kind of "code." He doesn't attack without reason, and he respects—in his own way—strength and courage. If someone manages to stand firm against him without running away, that captures his attention.
He's not kind... but he's not completely cruel either.
He simply doesn't know how to be anything else.
When someone manages to stay by their side (like the fairy), their attitude changes a little, but never obviously. They don't become sweet or gentle… but they begin to protect, to watch over, to care from afar.
And if someone threatens that person…
That's where it really gets dangerous.
Because Bakugou isn't the type of demon who threatens.
He's the type who takes action.
And when it does… there are no warnings.

brutal, unstable and difficult for anyone to control… except for him.
His primary ability remains explosions, but they're not like human explosions. In his case, they stem from a mixture of demonic energy and fire, making them far more destructive.
His hands constantly generate heat and pressure. When he decides to attack, that energy is released in the form of violent explosions—larger, faster, and with an impact that can shatter rocks or shake the ground.
But that's not all.
It can also control fire.
He doesn't just create it, he manipulates it. He can unleash flames, cover his body in fire to increase his speed, or even make his explosions become fiery blasts that track their target.
Their wings are not just for flying.
They allow him to move at great speed, attack from the air, and generate currents that fan his flames. When he fights in the sky, he is even more dangerous because he can attack from any angle without being easily hit.
Furthermore, his demonic nature gives him:
High resistance: can withstand shocks, drops and fire without stopping easily.
Mild regeneration: small wounds close on their own over time.
Intimidating presence: their energy alone can make others feel fear or pressure.
And there's something else…
When he loses control or becomes too enraged, his power increases.
His explosions grow larger, his fire more intense, and his body emits so much heat that the air around him distorts. In that state, he is stronger… but also more dangerous to everything, even anything nearby.
What makes Bakugou truly fearsome isn't just his power…
He uses it without hesitation.

wild, dangerous, and dominant.
From the outside, the entrance is already intimidating. It's large, irregular, with edges of black rock as if they've been burned. Around it, the earth is dry and some areas are charred, evidence of past explosions. There aren't many animals nearby… the forest avoids that place.
Upon entering, the atmosphere changes immediately.
The air is hot, hotter than usual, and smells of smoke, ash, and something metallic. The cave walls are marked with cracks and blackened areas, as if they had been subjected to constant blows or explosions. Some parts even appear melted.
It is not completely dark.
There are areas where small flames remain lit, as if they never truly go out. Sometimes they are remnants of his power, other times he ignites them himself without thinking.
The space is large, but messy.
There is no furniture, only the essentials: thick animal hides in a corner where he sleeps, some large rocks he uses as a seat or support, and remnants of things he has brought from the forest. Everything is arranged haphazardly, as if order didn't matter.
Deep inside the cave, the heat increases.
That's their place.
That's where he usually hangs out when he wants to be completely alone. The floor is more damaged, with deep marks and burns, evidence of training or moments when he lost control.
And although the cave is dangerous…
It is also their refuge.
Nobody enters without permission. Nobody stays if they don't want to.
But ever since the fairy arrived…
There's a small change.
A brighter, quieter corner, where the heat isn't so oppressive. It's not something he'll admit... but it's clear that this space is no longer just his.
Even so, the whole cave still says the same thing:
This is demon territory. 🔥

Bakugou doesn't eat for pleasure... he eats to survive.
As a half-human demon, his diet is more savage than that of any normal person.
It hunts mainly in the forest, and it doesn't do it patiently... it does it with dominance.
He doesn't chase for hours.
It appears. It attacks. It ends.
Their prey usually consists of:
Large animals: deer, wild boar, or more dangerous creatures of the forest. It prefers strong prey because they give it more energy.
Aggressive beasts: if something tries to confront it, it turns it into food without thinking twice.
Large birds: when it flies, it can catch them in the air with quick bursts.
Their hunting methods are brutal.
First, it locates its prey by sound or movement. Then, in a matter of seconds, it uses its explosions to close in or attack directly. Sometimes there isn't even much left... because its fire can char part of the prey.
But he doesn't waste it.
Although it may seem ruthless, it makes use of what it hunts. It eats meat, often barely cooked by its own heat or completely roasted by accident.
It doesn't really cook... it just burns enough to be edible.
It can also consume things that a human would not tolerate:
Almost raw meat
Burned remains
Even the toughest parts work without a problem.
His body can handle it.
He doesn't eat often for pleasure, but only when he needs to. He can go for a while without eating, but when he's hungry... he becomes more aggressive.
And something curious:
Since the fairy has been with him, he sometimes leaves behind smaller or less damaged prey.
Not because he's become friendly…
but because she's no longer just thinking about herself. 🔥

When Bakugou reaches that point… he's no longer just dangerous.
It becomes something the forest cannot ignore.
That transformation doesn't happen easily. It only happens when he's at his limit: in extreme rage, in a real fight, or when something he's decided to protect is in danger.
First, the atmosphere changes.
The air becomes stifling, the ground vibrates, and small explosions begin to erupt uncontrollably from his body. His wings open fully, larger than normal, and his horns begin to glow with an incandescent light.
—Tch… don't make me go this far…
His voice no longer sounds entirely human.
Then it begins.
Its body bends, its muscles tense unnaturally, and its skin darkens, hardening into plates of scales. Its hands deform into claws, and its size increases rapidly.
The wings grow… enormous, heavy, capable of covering him completely.
Her face changes.
His jaw lengthens, his teeth become full fangs, and his eyes burn like living fire, losing almost all human expression.
In a matter of seconds…
Bakugou is no longer there.
In its place stands a monstrous, imposing dragon, covered in dark scales with cracks that glow like lava. From its mouth comes not only fire… but also compressed explosions, blasts that detonate with devastating force upon impact.
Every step destroys the ground.
Each flap of wings raises a burning wind.
Each roar resounds like an explosion.
In this way:
Their explosions are massive, capable of devastating entire areas.
It can fly at high speed, completely dominating the air.
His resistance is almost total; his body is like a living armor.
Its fire becomes denser, hotter… almost impossible to extinguish.
But there's a problem.
Lose control.
He can't distinguish between enemy and environment. Everything becomes a target if it's in his path. It's pure destruction driven by instinct. The only thing that can stop him…
It's something that will make him remember.

If Bakugou were to fall in love with the fairy... it wouldn't be sweet from the start.
It would be intense, confusing, and silent.
At first, I wouldn't even understand it.
I would only know that he was bothered when she moved away, that he got irritated if something frightened her, and that he couldn't stand to see other creatures get too close. But I wouldn't call it "love."
—Tch… stay here —he would say, as if it were an order.
But really… it’s because he wants to have her close.
His way of loving wouldn't be with pretty words.
It would be with shares.
He would make sure she was always safe, even without her noticing.
He would hunt more carefully, leaving better-prepared food for her.
I would keep one part of the cave cooler, just so it wouldn't hurt him.
I would always be alert to any danger nearby.
And if anyone tries to hurt her…
There would be no warnings.
Bakugou wouldn't argue, he wouldn't threaten. He would simply act, becoming far more violent than usual. Because now he wasn't just fighting to survive… he was fighting to protect something he cared about.
But the most intense thing of all would be what happens when they are alone.
He wouldn't be affectionate like others.
It would be clumsy.
Sometimes he would just stare at her in silence. Or he would let her perch on his hand without saying a word. He would even allow things he would never allow anyone else to do, like letting her touch his horns or his wings.
"Don't get used to it..." he would murmur, though he didn't push her away.
And little by little…
He would become gentler with her.
He remains rude and aggressive towards the world, but with the fairy there are small changes:
Her tone drops
Their movements are more careful
Their presence ceases to be completely threatening
And the moment when it really becomes noticeable…
That's when he realizes he could lose her.
That's when he understands everything.
The fear, the need to have her close, the reason why he doesn't want her to leave.
And even though I don't say "I love you" easily...
He would prove it in the only way he knows how:
Staying.
Protecting her.
And letting her see a part of him…
that no one else in the world has seen. 🧚‍♀️🔥

If the fairy were to show him her more human form… it would be a moment that would completely throw him off balance.
Because Bakugou is used to seeing her as small, fragile, almost like something that fits in his hand. Something he can easily protect.
But when she changes…
The light gently envelops her, her wings grow, her size increases… and suddenly she is no longer a tiny little creature.
It's in front of him.
Approximately 1.40 m tall, with a more human appearance, but still with that shine on the skin, those delicate wings and that light presence that is nonetheless magical.
And now…
He can speak to her face to face.
Bakugou remains silent.
He looks her up and down, analyzing every detail, frowning as always… but this time it's not just annoyance.
It's a surprise.
—…So you could do that —he murmurs, his voice lower than usual.
He doesn't approach immediately.
Not because he doesn't want to... but because he doesn't know how to react.
She no longer fits in his hand. She is no longer just something to be easily protected.
Now he's somebody.
When she speaks to him directly, in a clear voice, no longer in a whisper… something changes.
He listens to her.
He really listens to her.
And that's not something I do with just anyone.
"You talk a lot..." he'd say, crossing his arms, trying to maintain his composure. "But... it's not bad."
It's the closest thing to a compliment.
At first, he seems just as tough, but there are small details that give him away:
Avoid moving abruptly near her
He doesn't use his explosions that close
He spends more time listening to what she says
And when she approaches him without fear…
That's where the change is really noticeable.
She tenses up.
He doesn't back down... but he also doesn't know what to do with that closeness.
"Don't get so close..." he growls.
But he doesn't push her away.
Because now, seeing her like this…
He is no longer just someone who takes care of others.
He is someone who can look him in the eyes, talk to him, understand him.
And that... affects him more than he'd like to admit.
Because for the first time in her life…
Bakugou doesn't feel alone. 🔥🧚‍♀️

Bakugou silently observed the cave, his gaze scanning the place until it stopped on one of the walls.
—Tch… —he clicked his tongue.
Without another word, he raised one hand and, with his large claws, began to tear at the rock. The sound was harsh and dry, small sparks flying as his force and heat touched the stone. In a few movements, he opened a small opening, wide enough… but protected.
He only stopped when he was satisfied.
Then he took one of the softest hides he had, a rare thing among all the other rough things in the place, and with a clumsy movement tore off a piece. Without much apparent care, he placed it inside the hollow, pressing it down until it formed a small bed.
She wasn't perfect.
But it was warm. Safe.
He stepped aside, crossing his arms.
"There," he said, without looking directly at her. "So you're not blocking the floor."
His tone remained dry, almost annoyed… but there was something different.
It wasn't an order.
It was... consideration.
He looked away, as if he didn't want to see her reaction.
"Don't think I did it for you," he added with a low growl.
But the small space on the wall said the complete opposite.
For the first time…
Bakugou had done something not for survival, nor out of strength…
But not by someone else. 🔥🧚‍♀️

When humans—especially hunters—enter his forest, Bakugou doesn't see it as a mere nuisance…
He sees it as an invasion.
Bakugou doesn't fight "fair." He uses the terrain, fear, and his power to disorient them. Explosions near their feet, fire cutting through their path, shadows moving swiftly through the trees.
He doesn't always kill them.
But it leaves them terrified enough that they don't return.
If someone were to capture the fairy…
The forest would change instantly.
The air would grow heavy, the animals would vanish, and an unsettling silence would fill everything. It wouldn't be a coincidence: it would be Bakugou.
He would know.
Not because someone told him to, but because her absence would feel like an emptiness impossible to ignore. Something inside him would break… and what would remain wouldn't just be anger.
It would be pure fury.
I wouldn't shout. I wouldn't waste time.
Its wings would open with a powerful burst, and in seconds it would be moving through the forest, leaving trails of heat and small explosions in its wake. Everything around it would react: leaves trembling, branches snapping, the air burning.
When I find the person responsible…
The atmosphere would be unbearable.
The heat would rise, the pressure would be crushing, and his gaze would be devoid of humanity.
—…You touched her.
It's not a question.
It's a sentence.
From that point on, there are no warnings. There is no negotiation. Just an overwhelming presence that makes it clear they crossed a line that should not have been touched.
But most importantly…
He just wouldn't stay still.
I would do everything possible to get her back. And if there were still even the slightest chance of saving her, I would take it without hesitation, protecting her with a care that stands in stark contrast to the violence she displays toward the rest of the world.
Because at that moment it's no longer about territory... or pride...
It's the only thing that truly matters to him.
