Chapter 5: Naruto vs Nomu

The tension in the rescue station could be cut with a knife, almost all the villains were defeated by the same students who had gathered at the entrance of the building, however among them were absent Yaoyorozu, Asui, Midoriya, Uraraka and finally Naruto, however it was not difficult to find them since a loud animal roar caught everyone's attention.

"What's that-o!" asked with half Toru who saw just like the others that beast that just a few minutes ago defeated his sensei and one of the strongest of his class, now that being was next to the villains in front of his companions who were behind the Uzumaki.

Returning to where the villains were we see that these were surprised and annoyed by the unexpected appearance of the blond who now showed a strange eye that was previously hidden by the bandages the same as his bandana, "You do not know when to give up right?" asked mockingly Kurogiri who saw an interesting detail, the brat's wounds were healing at a slow pace, was that his peculiarity, regeneration, nothing out of the ordinary, that Quick was varied in some users that could be found.

"You lost to Nomu in just seconds, what makes you think you will win now?" asked this time with annoyance Shigaraki who was impatient at the arrival of All might, he disliked his father wasting time, settling his hand on his face he sighed and scratched the back of his neck, that eye the arrogant blond had was making him uncomfortable.

"Why do I think I can win now?" asked Naruto seriously who tightened his grip on his sword, "do you think you can come and attack my comrades with killing intent? I'm not like the other cape wearing heroes you've met...I'm not going to win...I'm going to kill you" both villains tensed at that threat and for the shinobi to say it so seriously was to be taken seriously.

"Uzumaki-san this is not the time to say that! He is too powerful and he will kill you! We must escape and get help! I ask you to use your reason!" was the shout of Momo who was behind the Uzumaki, she as well as the others were scared, they saw what those villains were capable of. The black hair earned the gaze of the blond who only kept his attack stance.

"You're right, you guys should escape and look for help, I'll keep you busy" replied calmly the shinobi who brought his left wrist to his mouth and easily untied the bandages so that they fell and showed a strange drawing with several strokes.

"But..." the dark haired teenager tried to reply, but the look of the shinobi made her take a few steps back, finally her hand was taken by a nervous Asui who along with Deku and Uraraka were ready to leave with the green hair carrying their sensei, finally the teenagers backed up to run away to where their other companions were.

"You think we'll let them go?" asked Shigaraki irritably who was about to order his prized Nomu to kill the group of students, however he was transported by Kurogiri who opened a portal as shurikens flew at them, appearing in the distance the three villains were in a rocky area of the disaster station.

"Now we can go for the nanny-" Kurogiri could not continue speaking as some papers lit on fire fell on them, the Nomu automatically grabbed their leader and covered him from most of the explosions that came from those strange papers with weird writings, a large cloud of dust rose when the explosions ended, lying on the ground the mist being watched angrily as the metal cylinder that held him together was damaged.

"First with the annoyances" the purple villain opened his eyes in disbelief when he heard the voice of the shinobi behind him, before he gave act his cylinder was pierced by the Uzumaki's sword, releasing sparks this one suffered great damage, "I don't know how to kill you, but these must be important" pulling his sword out of that strange object Naruto kicked it and pushed it away from him, it seemed to kill him seeing that the mist was now dispersed and only a little remained in the metal cylinder.

"Grrrraaa!" the blond had to back up when the Nomu ran at full speed against him, the dark being breaking the ground under him ran against his target and threw a strong right, however this was dodged, hitting the ground he destroyed it creating a large crater, spinning around the Nomu saw how hundreds of shuriken and kunais came against him.

But the dark giant didn't bother to dodge them, all more weapons dug into his body, but didn't get to deepen the cut due to thick skin of the abnormal being that ran again against the Uzumaki that dodged the rain of blows on him, at a speed that normal humans could not follow was seen as the shinobi dodged each blow skillfully, with his sharingan shining with intensity the teenager tightened the grip on his sword.

In a burst of speed he dodged a left that was going to his head, passing under the Nomu he gave a cut in the right side area of the creature, with a scream of agony Nomu saw how blood came out before the great cut he received, but the attack did not end there since the Uzumaki fell on him at full speed and had his sword covered with an electric blue glow that was accompanied by small rays that surrounded the sword.

Giving a horizontal cut the blond was able to cut the left hand of his enemy who tried to cover himself from the cut, seeing the hand fall Naruto was going to attack again, but he had to put his arms as a shield when the Nomu with his right arm gave him a strong blow that made him go back several meters, skidding backwards the shinobi stuck his sword in the ground to stop his skid.

"..." kneeling on the ground he watched carefully as the wound of his enemy had closed while his lost hand grew back, in just a few seconds the strange being was already recovered from all attack, "Regeneration almost instantaneous, has a speed and strength greater than mine ... will not be easy" out of his thoughts he sheathed his sword, forming hand seals saw his enemy came back against him, "We will see how much you can endure" colliding their hands made a glow was born in his hands.

To the disbelief of all the spectators some rays emerged from the hands of the Uzumaki, all these flew against their target hitting the target, the Nomu was paralyzed before the great electric shock that ran through his whole body, trembling before the shocks he stepped back when the shinobi ran against him and gave him a strong blow in the stomach, and then a kick that took him off the ground, flying a few meters from the ground he was returned to the ground before a downward kick of the Uzumaki that landed in front of him.

"Now!" drawing his sword again Naruto gave a big cut to the stomach of his enemy, spinning around he began to give several cuts in different areas of the Nomu's body that was still stunned by the electric shock and the last blows, skidding across the ground the blond was located behind his enemy and gave a cut behind the Nomu's knees, cutting his tendons he saw successfully as his enemy fell kneeling.

Blood was staining the floor and his clothes, but that did not matter now, taking his sword with force he looked for the vital point, the exposed brain on the top of the head, jumping up and down he was going to give the final blow.

Meanwhile with the students we see how they were stupefied at such a demonstration of brutality, some felt the urge to vomit at the sight of the large amount of blood staining the floor and bathing the Uzumaki who was attacking with precision and brutality to his enemy who was screaming in agony at being practically mutilated and with blood spurting from his body.

"He's not planning to kill him, is he?" asked Kaminari in fear who felt disgusted as pieces of flesh fell from the Nomu who kept screaming in pain.

"..." several looked at each other with concern, that thing maybe was a person, it wouldn't be the first time that a person had such a monstrous physical appearance because of its peculiarity, many doubted what to think and could only be spectators of the carnage in front of them.

Falling on enemy Naruto was going to give the final blow with his sword, what he didn't expect is that the Nomu stood up and opening his jaw bit the sword, "Ahg!" losing the air from his lungs the shinobi was hit in the center of his stomach, losing the grip on his sword this was swallowed by the huge being that ran against him, the shinobi could barely cover himself when the giant fists of his opponent fell on him.

"It's useless for you to try to win" in the distance an injured Shigaraki got up from the ground with some minor scratches and burns, the previous explosion came to affect him even as the Nomu received most of the blast, with joy he watched as 'his' creation was savagely attacking the arrogant blond who barely managed to get to cover himself, "Nomu was created with the goal of killing All might, it is designed to withstand even the strongest blows of the peace symbol, you don't stand a chance"

Naruto only grunted when he heard the annoying subject, being on his back on the ground he suffered the severe blows that were burying him in the ground, separating his arms he used them to propel himself upwards and kick the Nomu's chin, falling to the distance he tried to think of a new plan of action, however he did not have time since his enemy was already in front of him.

Being grabbed by his head he was slammed against the ground causing a great roar, the Nomu without mercy began to run with his victim in the palm of his hand, leaving a ditch in his path with the body of the Uzumaki he threw him into the air, jumping up to him and hit him with force causing him to fly at full speed against the ground, falling with brutality the shinobi left a crater when he hit a concrete pillar.

"Grraaa!" but his punishment did not end there as he was tackled by his enemy that went completely through the concrete pillar taking him with him, being taken by his left arm the Uzumaki was smashed against the ground repeatedly. With each blow the shinobi was hurt more and more, with blood running down from his head and back he was taken between Nomu's hands who mercilessly began to squeeze his head to crush it.

With his bones being cracked before the attack he was suffering the blond gritted his teeth in pain, lifting his left arm he knew he was with fractures and with his shoulders out of place, looking angrily at the monster he took out a kunai from his back pouch and using his only useful arm he stuck the weapon in the left eye of Nomu who had to let go before the attack to one of his eyes.

"..." falling to his knees the shinobi tried to recover, only to see his enemy's fist smash into his face, flying off the ground he flew through the air until he hit a wall, getting embedded he saw with blood running down from his mouth, he saw how the creature was suffering from the weapon that hit his eye, looking down he saw that he was only about twenty meters above his classmates, moving forward he let himself fall.

Before he could hit the ground he felt the as a long tongue wrapped around his torso, Asui slowly lowered the Uzumaki to the ground, "Are you alright Uzumaki-san?" asked the frog girl worriedly causing her tongue to return to her mouth, several of her other classmates also gathered around him seeing the shinobi's deplorable state.

"Break down that door... and get out" he said slowly as he remained kneeling, he felt like some ribs were broken and his skull was possibly cracking.

"We can't, it's an armored door that even with our Quick is impossible to break down" explained a serious Midoriya who was thinking of breaking down the door with a single blow with his quirk to the max on one of his arms. "We can help you, you alone can't take him" assured the green haired teenager who was seconded by some of his teammates who were ready to fight.

"You can't, you'll only get yourselves killed" answered with severe seriousness the blond who brought his right hand to his left shoulder, producing an unpleasant sound and rearranging his shoulders, moving his arm he saw that he was already better, "..." opening his eyes wide he heard a roar.

"Here it comes!" shouted Kirishima with force that made his body activate its peculiarity, climbing up the platform the Nomu with one eye less ran against the students, reaching the entrance he ran against his target, however on his way he met Bakugo who pointed his hands against the villain, with the grenades on his wrists glowing with intensity he activated the mechanism.

Bakugo smiled arrogantly, he defeated the thing that had wiped the floor with the Uzumaki, with a trembling arms he took a deep breath, that was the biggest explosion he had produced to date.

But his victory did not last because among the cloud of dust emerged the Nomu that was unharmed, running the great beast attacked the shocked Katsuki who did not even manage to move when he was knocked to the ground by the fist of the Nomu that was now on him, raising his hands the dark being was going to crush the blond explosive that had been stunned and very hurt by such a blow he received.

When the villain was about to finish with the student he was hit on his head by Midoriya who had given a surprise attack using his peculiarity on his right arm, forcing the monster back by the strong sling of shock and force, the green haired teenager fell to the ground to hold his useless arm in pain, "Now Todoroki-san! " with that shout the student threw herself on Katsuki to cover him with a large mass of ice that flew over him and gave a direct hit to the Nomu who grunted as a large layer of ice enveloped him, in just a few seconds he was enclosed in a gigantic tempane of solid ice.

"..." Sighing a cold breath the mixed haired girl lowered her right hand that had some ice frost on it, frowning she saw a mountain of ice that reached up to the roof of the building and had a hacho of tens of meters, "...?" squinting her eyes she watched as the figure inside the ice began to tremble to quickly crack all the ice that began to disrupt the mountain.

With a blast of out brute Nomu broke free and ran against the ice girl who barely saw the monster already in front of her, however at the last second she was pushed out of the way by Naruto who tackled the Nomu to grab him by his torso and pull him off the platform, both fell several meters asta finally crashing into the hard concrete.

"Shit..." getting up the shinobi gritted his teeth as he saw that his enemy was already on his feet.

"Just ask for help, you know that thing has the minimum strength of Tsunade Senju and the superior speed that of a Jounin, even if it is just brute strength it is still a being that can crush you if you keep playing" the Biju's words made the shinobi give a snort, he knew where this would go, "You will let a being inferior to you kill you if you don't give up your pride, you know the magic words" the voice of the nine tailed vixen dry as the Nomu charged at him again.

Using his arms as a shield the shinobi resisted a blow that made him go back a few good meters to fall back to his feet, "I can handle this... without your help" taking his right hand to his seal on his left wrist he made some spheres appear, throwing them to the ground caused a dense cloud of smoke to cover the whole area, "I'm not giving it all yet" with those words the shinobi got lost in the white smoke.

"Where is he?" asked Mineta with fear that like his companions were watching the whole fight, now they could only see the cloud of smoke that was covering the whole area, the silence was sepulchral and the tension was too much.

But all that silence was broken when a strong expansive slingshot was felt, all the smoke was dispersed to reveal how Naruto had connected his fist against the stomach of the Nomu that flew backwards dragging his feet trying to stop his skid, but he didn't manage to do it since behind him appeared the Uzumaki who gave a kick that bent in a disgusting way the back of the giant being that flew against one of the many buildings of the place destroying a building of the disaster area, the whole building of 10 floors shook and fell on the Nomu that remained under tons of debris.

"..." Stomping hard Naruto showed to have had minimal growth in his muscles at the same time his skin turned slightly red and veins began to stand out on his forehead, with his sharingan glowing fiercely the shinobi took attack stance which was to keep his legs apart and bent, while his arms were spread apart, one entando pointing at his enemy with open palm and bent thumb, as for his other arm this was bent at a 45° angle close to his body, "Third gate... Seimon: Kai! (door of life open)" giving a deep breath the shinobi stood his ground, with seriousness he watched as the rubble where the beast was buried began to shake and in an explosion from outside this rubble flew out showing a furious Nomu.

"Grrr" with blood pouring down from his missing eye the Nomu glared angrily at the Uzumaki before him, with an animal roar the being ran at him, this was mimicked by the blond who also ran at him.

Before the eyes of the spectators both opponents collided forming a strong shock sling that slightly cracked the ground and produced a strong air current that knocked down more than one student, Naruto gave a right that was answered in the same way, The two powerful blows collided and countered each other forming a powerful shock sling, grunting the shinobi lost before the battle of forces, retreating the blond dodged another blow and leaning his hands on the ground gave a kick in the center of the stomach of the abnormal being.

Sending his enemy flying the Uzumaki ran and bombarded him with punches and kicks keeping him in the air, running at full speed the shinobi appeared in front of the Nomu and sent him to the ground with a downward kick that created a large crater, raising a large layer of dust the Nomu was buried under the rubble, landing in front of the crater the shinobi breathed in an agitated way.

But his momentary rest was interrupted when among the rubble emerged his enemy that caught the shinobi's face and brutally smashed him to the ground, the Nomu violently raised his big arms and hit his fallen enemy repeatedly causing the crater to grow more with each blow, at the tenth blow there was already a crater of more than 100 meters in diameter and 20 meters deep.

"They are killing him we have to do something!" was the cry of Ochako who heard each blow that shook the ground and created strong expansive slingshots, with horror the chestnut could only cry of anguish to see a boy of his age beaten in this way, this was the same in several of his companions who could only watch.

"Midoriya no!" Shoji had to use his arms to firmly hold the green haired teenager who was planning to take action, "If you act you will not only be a hindrance to Uzumaki-san, but you do not risk your life" with firmness the giant held the arm of the teenager who was ready to go, however everyone turned their gazes to where they heard footsteps.

"..." with a determined and serious expression Shiori was about to jump and take action, she could not stand idly by and just watch, this caused several to look at each other with doubt, they were willing to risk all their lives for a classmate, the answer was given when some walked to stand next to the girl with mixed hair, "We must give it all to gain time... until someone else arrives".

The students nodded their heads at the words of their companion, when they were going to act they heard it, an electric sound and cut the flesh, again in the crater we can see among the cloud of dust a sheet of electricity that was 5 meters long and was formed entirely of electricity, the electric beam gradually faded to show that it came from the right hand of the Uzumaki that gradually rose from the ground.

Before him was his enemy who remained still and motionless, however a red line began to form on his torso, in a grotesque way the being was divided in half, his legs and part of his stomach were separated from his body by a horizontal cut, with the upper part of his body falling to the ground in a heavy way a geyser of blood bathed the feet of the Uzumaki who watched as his sword that was swallowed earlier fell at his feet.

"... "leaning down he took his sword bathed in blood and watched how quickly the enemy was regenerating his legs, without hesitation he raised his sword and pierced the head of the Numo, the whole body of the giant being spasmed and the regeneration stopped, A sepulchral silence was formed when the Uzumaki took out his sword and put it back in its sheath, with a trembling of arms and legs the blond looked at the Nomu that now did not move in the slightest, implying that he was dead, raising his eyes the blond looked at the last villain standing.

"Impossible-e" stepping back Shigaraki scratched the back of his neck hard to the point of drawing blood, 'his' creation was killed, he was supposed to have killed All might, he was supposed to have destroyed the peace symbol, but he, "You..." looking furiously at the shinobi he walked up to him, after only a few seconds both teenagers were facing each other, a tense silence formed between them as their gazes collided.

"No doubt it was difficult, but not everything is brute force" without stopping trembling the shinobi felt his muscles throbbing with pain, the only way to have so close the Nomu to give a direct hit was to increase his strength and resistance with the internal doors, with an attack that would damage enough his enemy with the objective of paralyzing him it was crucial to end his life before he regenerated, "Who sent you? I doubt that someone like you has the ability to alter a person genetically to create that aberration" in an instant the shinobi was holding Shigaraki's neck with his right hand and lifted him off the ground, "I won't say it again... who sent you?" he asked again with a gravelly voice as he tightened his grip on the villain, but his only response was the dry laughter of the masked man.

Slowly the villain put his hands on the arm of the Uzumaki to look him in the eyes, "All for One" with words Shigaraki did it, Naruto had to let go of the villain when he felt the abominable pain in his arms that felt like it was burning, stunned he saw how his skin began to fall apart leaving his muscles red hot and the blood began to come out, choking the scream of pain he fell to his knees, the use of the internal parts and now this strange attack by being touched by the villain made the pain unbearable.

"What the hell did you do!" he asked angrily seeing his arm in such a state, breathing heavily he tried to block the pain from his mind, getting up again he saw the arrogant smile of the villain who stepped back as a portal opened behind him, slowly Kurogiri formed behind his leader and took him away leaving the Uzumaki alone, "Damn!" he should have killed him when he could, he underestimated him, he didn't know that the guy possessed a peculiarity that allowed him to break down flesh at this speed.

Looking around he saw that some of the remaining villains had recovered, however all of them were also spectators of the Uzumaki's capabilities, "Don't kill us" was the whisper of a woman who had her hair formed by snakes, they were all scared knowing that if that guy could kill the best weapon of their organization, they wouldn't stand a chance.

With his arm dripping blood the shinobi looked at the villains who were left behind by their leader, "Why not? You would kill me if you had the chance" those clear words were heard by everyone including the A-Class who didn't know what to think when the Uzumaki thought of finishing off the remaining villains, "You will live... just surrender" understanding the message the villains dropped to their knees and put their hands behind their heads.

Just at that moment the door of the disaster center was blown off by a loud bang, appearing next to the students appeared an extremely serious All might, he looked confused at all the students on the entrance platform, lowering his sight he found the image of a badly wounded Uzumaki who had near him a mutilated body of a dark and huge being, also dozens of people who were kneeling in front of him.

Only seconds later more heroes arrived along with an exhausted Lida who saw the scene before them, All might and other heroes saw how calmly the Uzumaki began to walk to reach the exit of the building, his condition was deplorable, he had wounds in several areas of his body, his right arm was dripping blood to have the flesh of his muscles exposed, he was only wearing part of his torn jacket that was bathed in blood as well as his own hands, Blood dripped down from his forehead and fell on the right side of his face that only highlighted more his shining sharingan, it was an image that would give nightmares to some of the students who moved out of the way of the shinobi, no one moved or said anything when the shinobi limping slightly walked out the front door along with the professional heroes and classmates of his class. A single question was going through the minds of the heroes who had just arrived.

What had just happened?
