Naruto In My Hero Academia

A sleepless night.

It would be worth it though, seeing as he had to get Momo off this island as soon as possible. To do that, he would have to finish the mission, as much of it as he could, by himself and think up a plan to get off the island. He was going to be tired in the morning, but it was far more than worth it. Naruto looked at all of the documents that he had been able to take from the records, there were so many records of their illegal activities. Not like normal records, these records were testing data, data that was being used to record the progress of their illegal experimentation.

The Seed Bed.

It would seem that Kaguya was doing some independent actions, she planned on creating cloned children using her students, once they had reached the peak of their powers. She would then strategically place those children in orphanages across the world. Each child was going to be cloned and modified, so that inside each of their ċhėsts they would hold a chemical weapon that would explode and infect entire cities. The chemical weapon containing Kaguya's own DNA in it, and with her DNA all over the world, she would be in direct contact with everyone on the planet. She would be able to use her Quirk to rapidly absorb all of the energy from everyone, thus forcing the world's population to give in to her greatest wishes in order to survive another day.

"She's a sick fuċk... she's choosing to clone girls who are good looking, and with good Quirks, so that they are more likely to get adopted. Every student at this school thinks they are joining her army... but they are just pigs to the slaughter..." Naruto whispered to himself as he read over the documents. Reading these, he knew that this was the evidence that they needed to end the school, and put Kaguya away for the rest of her life. There was no way that any country would be able to ignore this, nor ignore the fact that Kaguya had already hacked into their citizen registry and created hundreds of false identities for her Clone Bombs. "... No... she has a back up site... if something happens to this school, she's going to escape to site B." Naruto read further into the file.

She had back up plans, and some of the information on the file was missing as well.

"So, it seems like there is a rat among us, time to exterminate."

Naruto grinned, and turned his head to see the true Kaguya standing behind him. His Hoshi no Tama was resting safely between Momo's sleeping brėȧsts, so Kaguya wasn't going to be able to steal that from him. Naruto turned around and faced her, before he put the file safely away under his shirt. The woman looked surprised that he was here, but the fact that all of her guards in the room were knocked out, showed her that her opponent was a skilled fighter, or a stealthy one. Naruto raised his fists up, and prepared for a fight.

"Come at me you pasty bitch." Naruto spat at her.

Her literally spat in her face when he said it, ending his sentence by giving her face a new coating of saliva. A vein bulged on her forehead, and he saw the signs of her Quirk activating, her horns glowing and the third eye on her forehead opening up.

"I'll drain your energy completely."

Naruto threw a punch at her, and she reached out with a surprisingly long reach, and grabbed his shoulder. Their battle started in an instant, and Kaguya felt a rush of potent life energy rush out of Naruto's body and into her own through her horns. Then, Naruto's punch connected with her face, and sent her flying backyards, though she landed on his feet. He was already running towards her, and she kicked him in the face as he let loose a powerful punch to her stomach.

"Try it, take as much as you think you can." Naruto sent her flying again, another chunk of his energy was gone. She slammed into the wall, bleeding from her split lip, but she wiped it away.

She sent him a gleeful look.

"You... you... your energy is absolutely massive... I've been stealing energy for over 160 years now... I'm going to suck you dry." Kaguya couldn't believe it. Even the girl from earlier, Naruko, couldn't even begin to compete with the amount of energy this boy had. This boy had enough energy in his body, through both being naturally gifted, and no doubt a life time of impossible levels of training, that he was like an ocean of power waiting to be drained.

She was going to suck him until he was a husk, all of that energy, if she added it to her own... no... he had so much energy, that if she suċkėd it all, she could gain his Quirk forever. She could become a deity with all of his power.

She could use it better than him anyway.

Kaguya's body started to glow blue, and she started to cover her body in years of stolen energy.

"I have a girlfriend, and she's been trying to do that for weeks now... get in line." Naruto stated, and he blocked a punch from her.

She drained more of his energy.

"No... I should let you live... you'll become a great battery for me... so be a good boy and SIT!" Kaguya shouted as she traded blows with Naruto. Increasing her strength beyond human levels with her stolen power. She looked at Naruto, expecting him to get sent flying by her might.

He tanked her attack, and headbutt her in the nose, pushing her back so that the two of them could punch each other in the faces.

"Take all the energy you want, but you won't put me down. I'm going to be All Right, and you can't change that." Naruto could feel power getting drained from his body. Through sheer willpower, he kept going forward. Every time his fists hit her, he had energy drained from him. Whenever she hit him, even more energy was pulled out of his body.

Several Kaguya guards entered the room.

"Master!"

"There, more power!" Kaguya's clones... they turned into raw energy and entered Kaguya's body. The glow around her body became brighter, and Naruto felt her energy absorption get stronger as well.

That didn't matter.

They continued to trade blows, faster and faster, her enhanced power slowly starting to match his own strength. Naruto took a hit to the nose that broke it, and pushed him back. Slowly, his attacks were no longer hitting her either, as her third eye started to move and track his movements.

'... I'm starting to understand... to steal energy, she needs that third eye open... her horns are the conduit for stolen energy, and her DNA is the vessel. Whatever energy she steals, she can use to enhance herself... the longer I fight her, the stronger she gets.' Naruto thought as he wiped his bloody nose and took a brief. He noticed something else.

Kaguya's injuries were vanishing as well, the glowing energy healing the injuries that he was giving her.

"My Quirk has granted me immortality, and I'm unmatched in physical combat. Just allow yourself to slip into an infinite dream. Defeating me is impossible." Kaguya taunted him when her injuries were finished healing.

Naruto smirked.

Impossible.

"... Then, I guess I can't be a real hero until I beat you... and if I defeat you, then you aren't an impossible challenge... I'll have to challenge myself further." Naruto spoke with a grin on his face. Naruto rushed towards her, stance changed, and when she threw a punch, he matched it with his own punch.

Naruto could hear the voice in his head.

Run!

"Boy, I am a goddess!" Kaguya proclaimed to him, and she punched him in the forehead. Her fist stopping and absorbing his power constantly now, since Naruto stopped moving, and just closed his eyes.

He took a deep breath.

-Inside Naruto-

Infinite darkness, Naruto could feel a festering hatred unlike any other all around him, consuming him. He could see two giant red eyes open up behind him, and he just glanced at them.

"... So... my Quirk really is sentient... hey... Monster Fox... for once in my life, shut the fuċk up. You're My Quirk and you better start acting like it. This is my body, you're just apart of it." Naruto turned and faced the red eyes, a confident grin on his face.

"You're nothing without your Quirk, you need our power!"

"... Dumbass... did you forget... this entire fight... I've been doing it... without my Quirk?" Naruto questioned himself, since his Quirk was just apart of himself. This voice was nothing more than apart of him, his darkest parts, but a part of him all the same. "... With or without my Quirk, I'm All Right... aren't I?" Naruto stared into the abyss.

He reached out into it, and pulled out a glowing light.

"Fine... just this time... use our power without hatred."

-Outside Naruto-

"This energy, it's amazing! Even after stealing so much, you're a monster!" Kaguya couldn't be more excited when she continued to steal Naruto's energy for several minutes straight, while he stood in place.

Naruto opened his eyes.

"I'm not a monster..." Naruto grinned, and showed his canines were longer than before, his eyes opening to show he had glowing blue eyes with slit pupils. Kaguya suddenly felt far more energy come out of Naruto's body, so much power that it was unlike anything she had ever suċkėd before. Naruto's whisker marks thickened, and Kaguya saw as his arms transformed, gaining golden, glowing fur on them, with black markings. "I'm a Monster Fox... now... eat this. Nine Tailed Smash!" Naruto punched her.

Kaguya summoned every single ounce of stolen energy, including all that she stole from Naruto, and guarded herself with it.

"WOAH!"

Toshinori, and Izuku, covered their faces with their arms when an unbelievable amount of power split the sky above them, and the ocean in front of them. They were literally able to see the split ocean, and the clouds move out of the way. They were just training Izuku to use his Quirk better, when suddenly an unbelievable amount of raw force shook... everything. Toshinori had to transform and use a full power punch of his own to fight back against the shock wave, to try and send it into the air.

"What was that!?" Izuku, he could see the shockwave was still travelling, All Might's punch having only been strong enough to change the direction of where the shock was travelling.

A powerful wind followed, and the ocean slowly started to return to normal, massive waves churning, the clouds still being moved.

"... I don't know... I've never seen anything that a full power punch wasn't able to overpower before..." Toshinori turned back to normal, and looked into the distance. He couldn't even see the source of the attack, it had been so far away.

No.

For some reason, he felt a sense of pride fill him, and he had no explanation why, for some off reason, he felt Naruto was responsible.

-Back with Naruto-

"Fuck... FUCK!" Naruto shouted as he looked at his practically destroyed right arm. Then, he looked at the damage that he had done. Half of the entire island had just been blown away by his attack, and he could see the moonlight in the once cloudy sky. His attack had destroyed half the island, and thankfully it looked like he had missed the school seeing as his attack was aimed outward from the school.

He really hoped that his attack's shockwave didn't make it back to Japan, that would really suck... it was pure luck that he didn't kill anyone at the school... well... looking at Kaguya's remains, he couldn't say that. All that remained of her was one of her horns and part of her skull.

So... that was how strong he could be if he mastered his Quirk.

Naruto dropped to his knees, and he could see Kaguya starting to regenerate from his attack. The little energy she had left was being used for that, so Naruto forced himself to stand back up, his transformation ended.

Next time... you will be consumed be your hatred.

"Hey Kaguya... I guess I'm not ready to be a hero yet... that challenge you gave me... was too easy..." Naruto spoke to nothing as he passed by her. No doubt he had woken the entire academy up with that attack, so he was going to have to get to Momo as soon as possible.

"Stop, intruder!"

It would seem getting back to Momo was going to be another challenge.
