[There is no new chapter, just change the dialogues so that they are better understood, sorry for the inconvenience].

[2.0: This update is due to the fact that the user Druss the Legend has commented that there are paragraphs where Jaune was referred to as a woman. I admit it, English is not a language that I dominate, I depend on translators to be able to do this fanfic].

Hello, if you are here reading this fic, well, it is my first time writing on this page, I almost always write on wattpad, not to say that English is not my native language, because what can be confused.

But I appreciate if you read this fic, I don't know if this can be considered an AU or a crossover, since it is the story of One Punch Man mixed with a bit of the history of RWBY, the characters of the latter replacing most of the first.

But hey, I'm retiring, I hope you enjoy it.

Chapter 1: The Strongest Blond.


Legends.

Stories told through time.

Humanity has become accustomed to telling stories, of heroes, being the good ones, and villains, being the bad ones.

Forgetting that reality is gray, that we descend from a forgotten past.

The human, born from dust, what made him different from other animals? His ability to reason, to want to make sense of things, to be the only one who applies morality.

Although it was difficult to apply reason with the creatures that surrounded him, an inescapable darkness, creatures of destruction.

The Grimm set his sights on the human being and his creations.

These two species collided, and it seemed that the grimms would return the human being to emptiness.

But when people are at their lowest moment, they look for hope in any light, no matter how small, they cling to it.

And with the passage of time, they managed to be at their level, what they found was appropriately called Dust.

Wielding the power of Dust, the human being managed to light his dark path, reaching civilization, and with that, life.

But even the biggest light...can be turned off when darkness overwhelms you.

It was what happened 45 years ago, it is not known exactly what happened, it was in a land of darkness, an arid wasteland, with rocky terrain and huge purple crystals.

In all that darkness, a purple streak of light was shot against the sky, it was so intense that it was seen throughout Remnant, and it was so powerful, it could be seen from space.

From that moment, the phenomenon occurred that only worsened Remnant's situation.

The "Unwanted Evolution."

It all started when a herd of Beowolves stormed an isolated village in the Kingdom of Mistral, the locals struggled but couldn't resist the overwhelming force of the grimms.

But the situation in the village changed when the Huntsmen arrived, elite warriors dedicated to fighting the grimms.

They quickly eliminated so many grimms present, until a Beowolf Alpha appeared, at first, they were not intimidated or worried.

But that feeling of confidence was replaced by amazement and confusion when they heard the Beowolf Alpha speak.

The Grimm were known to be smart, the older they are, the wiser they are, yet they still behaved like an animal, letting themselves be carried away by their hostile instincts.

Never having encountered a grimm capable of speaking, the Beowolf Alpha, thanks to its intelligence and cunning, was able to deceive the huntsmen, and with the support of the remaining beowolves, they murdered them, along with the villagers.

Thereafter Remnant went downhill.

More grimms spoke, they were smarter, they could reason and work better as a team, increasing their lethality and decreasing the number of huntsmen.

From then on, Remnant darkened again.


45 Years later.

We can appreciate a city located on the edge of a huge crater, located in the Kingdom of Atlas, the cold and snow were something everyday.

The gray fog covering the mainly industrial buildings with poor characteristics, their economic situation is not the best, even so, people try to continue with their lives.

But all that would end when a small one, which quickly turned into a gigantic explosion, leaving a huge crater full of rubble.

On top of a mound of earth and rubble, we can see a humanoid figure, resembling a dragon.

It can be seen that he is at least 4 meters tall, his rough, black skin, along with white bone-shaped spines along his body, including his external skull, a rib cage, and rows of spines.

A pair of large translucent red bat wings, along with its tail, accompanied by three bony tips and large claws on its feet and hands.

Its skull has a pair of large prominent horns and six yellowish red eyes. His jaw has teeth that run the length of his neck.

The Grimm looked around, then picked up momentum and jumped powerful, leaving another crater.

Keeping up in the air thanks to its wings, the Grimm extended its arms, from its hands began to generate balls of dark energy with purple glows.

"ROARGH!" The Grimm roared as he released the energy balls, destroying and exploding everything in its path.

Inside a control room full of blinking red holographic displays, some with the word "Alert" while others show images of the city and statistics.

"Its coming!" Shouted one of the workers in black suits looking at one of the screens while typing frantically.

"Who is available!?" Another worker asked.

"We confirm that Mercury Black and Elm Ederne are on the way." A woman replied as she typed quickly.

"I want the threat level!" Demanded a worker who had risen from a chair, with many holographic displays around him.

Upon returning to the city, we can see an unconscious young man on top of a rock, with pale skin, messy gray hair, dressed in a two-tone jacket with a partial slate gray and black zipper that covers the upper body.

The most characteristic thing about him, in addition to having black pants, are the leg prostheses that meet half of his thighs.

Accompanied, a few meters away, we can see an unconscious young adult with his arms outstretched, along with a hammer stuck in the ground.

She young adult is tall and muscular, tanned skin with medium brown hair along with a short ponytail.

She wears an Atlesian specialist uniform, a single-sleeved open white vest with blue accents, and a dark gray shirt. A red belt around her white pants and she is barefoot, except for some martial arts coats.

The Grimm in the distance was walking calmly, until a purple explosion suddenly appeared.

Far from the destruction, we can see a reporter with a safety helmet reporting the situation to the camera, while the civilians flee, we can appreciate that most of them have animal characteristics, such as ears, tails, etc.

"As you can see, there are explosions behind me, the ground shakes and there is a thunderous noise, the explosions do not stop ceasing, the Huntsmen Association is evaluating-"

An explosion appeared, cutting the signal, leaving more than static, which can be seen on a small television, the viewer, a young bald man, watched the television in silence.

"I think you should go."


Upon returning to the city, we can see that the Grimm continues to launch its energy balls, further destroying the city, until it stops when it hears a girl scream.

"Wah...wah...Mommy! Daddy!" The girl with wolf ears on her head cried out between sobs, the Grimm watched her until he walked towards her.

The girl continues to sob, the Grimm extended his right hand, which became five times larger than the girl.

The Grimm closed his hand tightly, but blinked when he saw that the girl had disappeared, while his arm returned to normal, he searched with his eyes, until he found a young man in a yellow cape, carefully lowering the girl.

"You are fast, who are you?" Asked the Grimm, he could see that the guy formed a small smile, then got up and crossed his arms.

It is a young man with light skin, blue eyes and bald head. He wore a long-sleeved black shirt under a bib, white armbands and shoulder pads with gold detailing, a brown belt with a gold buckle, dark navy jeans, brown long gloves, matching boots, and a yellow cape, held up by his shoulder pads.

"I'm just a guy who's Huntsman for fun." He replied with a bored face and a neutral tone of voice.

The Grimm just looked at him, if he didn't have his external skull, he would have frowned at the bald young man's words.

"What...what kind of stupid story is that?" The Grimm said as its wings expanded, giving it a threatening shape.

"My story is better, like my brothers, I was born from the Grimms Pools, but my birth was along with the contamination that you humans and faunus create!"

"I'm Vaccine Wyvern!" When he put a hand to his chest and called out her name, his voice deepened.

"Remnant is a living organism, you humans and faunus are nothing more than viruses that eat your life energy!"

"I was created to get rid of the evil civilization that you have!" As he shouted his speech, his voice became deep, his body started to get bigger, little by little he started to get down on all fours, his arms grew and joined his wings.

"I AM MOTHER NATURE'S WRATH!"

"YOU SAYING YOU DO IT FOR FUN? FOR FUN!?" His body finished growing, the humanoid being has been transformed into a giant quadruped, similar to a dragon.

"HOW DO YOU DARE TO FACE THE APOSTLE OF MOTHER NATURE FOR A SUCH VANAL REASON!?"

"WHAT COULD YOU EXPECT FROM A SIMPLE HUMA-"

POW!

One hit, I only need one hit the young man, so that the Grimm Wyvern has been ripped in half, and with air pressure, the nine nines from the explosions and contamination disappeared.

The young man stayed in the position that launched the hit, while the wreckage of the Wyvern fell to the ground, to later disintegrate.

He looked down at his smoking fist, a bead of sweat trickling down his forehead, as he frowned.

"Not again...I just needed a hit!" He mentally shouted as he fell to his knees and propped himself up with his hands.

"DAMN IT!" I scream with all the frustration in the world.


4 Years before.

"WAH!"

"KYA!"

"Kikikikikiki!"

"It's a grimm, you have to go!" The screams of civilians in the middle of some houses in the city of Vale were present, everyone was running except one.

It is a young man with light skin, blue eyes, messy blond hair, dressed in a black short-sleeved sweatshirt, with separate reddish-orange sleeves and brown wrist-length gloves with exposed fingers and small black plates.

There is a white diamond-shaped plate protecting his chest, along with some shoulder pads of the same color with gussets underneath them.

Blue jeans with a white patch on the left knee, two belts that cross each other in different shades of brown with small bags, black sneakers that have "left" and "right" on each corresponding side in black.

He has a sword tied to his left hip in a scabbard.

"Oh, what is this?"

The expressionless young man, looking without interest at the cause of so much fuss, a grimm, specifically a Beowolf.

A stooped wolf-like being, standing on its two legs, angular head, prominent ears, black skin, emanating a kind of black smoke, wears a bone-shaped mask with red markings.

Bone-shaped spines protruding from its back, arms and knees, its feet and hands are bent with long, sharp claws.

His bright yellow eyes leave a trail of red, proud of his height, as he is twice as tall as the young man in front of him.

"Are you sure you won't run away, kikikiki?" Beowolf asked as he raised one of his arms to attack the young man.

The only answer he had was a sigh from the blond young man, the Beowolf under his arm and he gave a little laugh.

"From what I see, you are a huntsman, on the other hand I was the victim of experiments by scientists, I broke free and ended up killing them." The Beowolf scratched the ground with his claws.

"If you are not running, you should prepare to fight, why don't you? Kikikiki."

The young man looked him in the eyes, still keeping his expressionless face.

"You want to die, is that it?"

"Well...not really, and you're wrong about something." Finally the blond spoke, the Beowolf listened carefully.

"I am not a huntsman, I am just a kid who was going to attend the initiation at Beacon Academy today. I wanted to be a huntsman, so much so that I falsified my documents in order to enter."

The Beowolf bowed his head, for the first time interested in what a human was saying.

"But my realistic side hit me, and I realized how stupid I was doing. Without training, without discipline, just half an hour ago I learned about the existence of the aura. How the hell was I going to be a huntsman?" The blond kept talking, little by little his head was lowered, while he closed his hands tightly.

"So I didn't go to the initiation, most likely it already started...I don't care anymore, and I'm not in the mood to run away...just because you're here."

The tension in the air was felt on the skin.

"What will happen now if I don't run away from you?" The blond asked without even looking at him, the Beowolf laughed, opening his jaw showing his teeth.

"Your eyes have no life, like mine, since we have that in common, this time I will let you live, I retire before a Huntsman comes." The Beowolf walked next to the blond, this turned his head to see him withdraw, for the grimm to stop.

"I recommend you take advantage of this, since the next time we meet, I will kill you, but don't worry, you are not the person I am looking for." The grimm turned his head, his tongue protruding from his jaw, and his eyes blinked in a red light.

"Hmmp?" The curious blond murmured.

"A boy in a white hair suit, and when I find him, I'll cut off his arms!" The Beowolf returned to his head and started walking.

"KIKIKI!" The Beowolf gave a great laugh, which gradually fades away from the blond, who shrugged and continued on his way.


The young man walked thinking about the situation that occurred a few minutes ago, looking around, he saw that he was walking next to a park, although empty of people, the birds singing, the sound of the fountain, a young white-haired man in a suit reading...

The blond blinked and stared at the young man, it seems they are the same age, although he seems a few years younger than him, white hair combed to the left with a small lock, blue eyes, light skin.

He wears a white short-sleeved shirt, the sleeves buttoned above his elbows with navy blue details, over his shirt he wears a light blue vest with a black scarf in the right chest pocket, a black tie, navy pants and black shoes.

You can see that he is reading, but not in a book, but in what looks like a folding holographic tablet.

The young man with white hair noticed the look they gave him, he closed his holographic tablet.

"Any problem?" The white-haired young man asked, a bead of sweat running down his forehead.

"Shit, could it be him?" Wondered the blond.

"Hey boy...don't open a Beowolf upset, right?" Hearing the question, the white-haired young man rubbed the back of his neck and avoided eye contact.

"Well...yes, I dressed him stupidly and took photos of him...don't look at me like that, after I did I realized it was stupid!" The young man tried to defend himself.

"Yes...it's him." The blond sighed.

"Please do not know me, I went to visit Vale without telling my father, I was very stressed and needed a new vision." As the white-haired young man explained his motives, the blond was totally engulfed in his thoughts.

"This one is in serious trouble, what do I do? Can I hide it? Should I protect him...no, I have no training, I can't even protect myself...the least I can do is tell him to leave."

But the blond had no time to say anything, as a wolf-shaped shadow appeared behind him, the Beowolf looked at the young man in a suit, who fell off the bench and tried to get away, so that the Beowolf would jump and land in front of him. The young man in the suit froze, unable to shut his mouth.

"You are mine." The Beowolf raised his arm and lowered it violently, blinking when he saw that the blond had launched himself towards the young man in a suit, saving him from his attack, the Beowolf looked at the small crater he made before looking at the blond.

"What the hell am I doing!?" The blond questioned, as he carefully left the young man in a suit still frozen.

"Child, you better run if you want to live!" The blond screamed, the young man in the suit blinked, then got up and walked away, but the Beowolf jumped into the middle, launched another blow, which was stopped by the blonde's scabbard that had become a shield.

"Hey what are you doing? You are stupid...why do you protect him instead of running away?" Beowolf asked as he walked away a little.

"Wait, I can't allow you to kill someone in my presence, I don't want to have a feeling of guilt, aside, are you going to kill him for a stupid joke?" The blond said with a forced smile, his body gave little tremors.

"You don't understand it, not only do I bother, I humble myself publicly, the members of my pack when they found out about the joke he made made fun of me." The Beowolf said, his eyes slowly bloodshot.

"That snowman dared to dress me like a cheap clown!" The Beowolf screamed as he picked up a device like the one the young man in a suit has, only very damaged, the photo shows on a page of a Beowolf dressed as a clown, a horrible clown.

"DARE TO TAKE PHOTOS OF ME AND POST THEM ON A PAGE!" The Beowolf roared, his eyes turning completely red.

"AND IF YOU ARE GOING TO PROTECT HIM, I WILL MAKE SURE YOU CANNOT ENROLL IN ANOTHER ACADEMY!"

"Hehe...hehe..." The blond's laughter confused the grimm, who had calmed down a bit.

"It's just...hehe, you reminded me of the villain from a comic I read, hehe..." The blond said with a smile, the Beowolf looked at him blankly.

Then launching himself at him and sending him flying with a blow, the Beowolf set his sights on the young man in the suit, who ran with a small shriek.

The grimm was ready to launch himself at him, but stopped when he received a blow to the back of the neck, turned his head, and received a blow to the face.

The blond after hitting him jumped back, his fighting pose is outdated, he held the sword like a club, his shield held him more or less well.

"Stop there, I won't let you kill him." The blond shook his head when he felt the blood pour into his right eye.

"My dream was always to be a hero, to protect people, without expecting anything in return." The blond confessed as he put his hands to his head and thundered his neck.

"That's why I came to Vale, to be a huntsmen, right now I can't do it, but hell, I can't stand idly by!" The blond shouted as he put himself in a better fighting position.

"COME BEOWOLF!"

"You, a hero? Do not make me laugh!" Shouted the Beowolf who threw a strong blow to his face, sending the blond flying, spitting blood in the process.

"You have no chance against me!" He claimed the Beowolf who grabbed him by the ankle and knocked him to the ground, destroying the earth in the process and leaving a crater.

"Your life ends...here!" The Beowolf said approaching a dying blond, to give him a hit, but the blond dodged jumping head-on.

In the jump the blond turns his shield into a scabbard and uncertain it inside the Beowolf's jaw.

The Beowolf blinked before feeling horrible pain, as the blond activated the mechanism and the sheath became a shield, piercing the Beowolf's jaw and head.

"ARRGH!" The Beowolf shouted as he put his hands in an attempt to remove the shield, but the blond hanging from the shield, with his other hand, slashed the grimm's hands with an accurate cut.

The Beowolf stopped screaming and fell to his knees, the blond turned the shield into a scabbard and lifted the corpse of the disintegrating Grimm.

The blond looked at the corpse, panting and trying not to drop his weapons, his blue eyes filled with intense light, the sensation of adrenaline in the battle was present.


Current Era.

Those same dull eyes looked around.

"Four years have passed...I trained so much that I went bald, I always thought that at any moment I would die, but now I am the strongest, a hero who can protect people." The blond thought as he walked through the areas of the city that were not affected by Vaccine Wyvern.

"What is this, what's wrong with me? My goal was to be the strongest, all my emotions pointed to that, so why don't I feel anything?" The blond questioned, looking at the horizon, in these years, he was able to improve his eyesight.

"If my eyes don't lie to me, I see a city, I'm already in Atlas, why not do the shopping?" The blond said before starting to run, leaving a trail of smoke.


Well, this would be the first chapter or prologue, whatever you want to call it, for the record that my way of publishing this, is that I adapt 2 chapters of the manga with scenes that only appear in the anime.

For the next one, the adaptation of a beloved cyborg will appear. Who do you think will take your place?

Well, I'm leaving.
