Disclaimer: First Chapter
Gelel Stones is created a LOT like a philosopher's stone, only the end results are... better in a way.
Story Start!

"So... we are just going to run away then. We aren't even going to try and fight!?" Yang shouted at Naruto, the very person who ordered that they run away. Naruto gave her a hard look, they were still on the boat going back to Vale, and thanks to some rough waves it would be over half an hour until they got back from this point. Yang, in her rage, had mostly gotten over her sea sickness... that and she had remembered she brought some pills for sea sickness.

It was mostly the pills.

"Yang, shut up." Naruto told her, not willing to put up with her questioning him at the moment.

She grit her teeth and looked down at him, he was sitting and she was standing, a look of anger in her eyes. The other men on the mission were still humiliated from their little lapse in judgement.

"What is up with you? You have been looking at that rock since we lost sight of the island?" Blake asked as she glanced at the Stone of Gelel that was in Naruto's hands. He looked at it with a frown on his face, he had yet to let go of any of the smaller or large fragments of the stones he had gotten. They were all with him, and he knew what they were too.

They were fragments of Haido's Gelel Stone, mere fragments but still powerful enough to grant immortality and infinite reserves.

"This rock... I know what it is, and I don't want to talk about it." Naruto told them, making sure they heard the fact he did NOT want to talk about what it was. Of course, he knew his friends, his friends could be very nosy about what they did.

"Wait, I thought it was Dust?" Velvet asked, and Naruto gripped his hand against the stone.

"No, this stone was struck by lightning while next to dust, fusing them together. This is in no way dust, it is evil." Naruto told them with his frown only growing more grim than before. He hated the fact that this world had one of his world's most dark secrets, one of humanities greatures failures.

The creation of Gelel Stones.

Demonis stones made through extremely demonic means.

"You know you will have to tell us eventually anyway right? The General is going to search through your memory and learn what they are." Penny told him, and Naruto sighed in annoyance for a second, before he nodded.

"This is a Stone of Gelel, these stones grant the people that use them amazing strength, speed, regenerative powers, and powers unique to the person using them." Naruto admitted, and he moved his hand away from Coco when she reached out to look at the stone. His reaction seemed to surprise everyone, mostly because he wasn't even letting them touch the stone.

"Whoa, what is with the hostile reaction?" Coco asked with a truly surprised look on her face. She hadn't expected him to reject her so much, when all she wanted to do was look at the stone.

"Power doesn't come without cost. Power you get by training costs you the time you took the train. Power given to you by another comes with the cost that person decides. What is the cost of the power of the Gelel Stone?" Pyrrha asked when she figured out what Naruto's problem with the stone was. She was surprised when Naruto shook his head, denying her statement.

"No cost, using this power has no cost to the user in the slightest. Gelel stones are just... evil." Naruto told them with a glare at the palm sized stone in his hand. He gripped it, but he made sure not to destroy it. His heart was filled with the most heated emotion in relation to the stone, a feeling of pure rage.

"Evil?" Velvet asked, not sure how a stone could be evil.

"How do you even know all of this? There has never once been a recording of anything even close to being called a Gelel Stone." Blake told Naruto, history being one of her good subjects. A stone of the power Naruto is talking about would be famous, or infamous. The boiling emotion rushing off of Naruto's face, clearly visible and truly palpable was rage.

"What does Gelel even mean?" Ruby asked, her own sea sickness pill finally taking affect, letting her move about normally.

"It means Gelel, that is literally the name of the stone. I don't want to explain why or how, at least not yet. Yes, these stones are evil." Naruto told them, and he could see that some of them... all of them were completely unsatisfied with his answer.

"Why are the stones evil?" Yang asked, trying to get the answer out of him with a constant barrage of questions.

"The ingredients in a Gelel Stone are not just natural. There is only one non-evil ingredient, and that is liquid energy from the Gelel Vein, which was located underneath the Isle of Demons." Naruto told them, and a crack appeared on the Gelel stone from the force of his grip. Naruto loosened his grip, because he knew that breaking it right now would be unwise.

Destroying a Gelel Stone through physical contact was unwise, it was best to use a strong energy attack to destroy it... and to free the beings inside of it.

"The... evil ingredients?" Fox asked, not completely sure he even wanted to know what was inside of the Gelel Stone.

"The flesh and blood... of children." Naruto told them, and they all gasped in shock.

"Chi-children!?" Ruby asked with wide, tear filled eyes. She had thought that the stone was pretty, but to think that the stone was actually the body of a child... she felt sick to her stomach.

"That is wrong." Yang said with a frown on her face, she wasn't saying he was wrong, she was saying what they were made of was wrong in the moral sense. It disgusted her.

"Those stones need to be destroyed!" Pyrrha demanded of Naruto, and he frowned.

"The children's spirits in these stones have been trapped for over 200 years... they have been forces to serve evil people who murder those who don't agree with them. They have gained power, become part of the stone... if the stone is destroyed the spirits release..." Naruto hinted at them, and it would seem that nobody got what he was hinting at.

Nobody at all got the fact that these children had been trapped for 200, technically way longer than that, years inside of stones... forces to suffer in anguish for eternity.

If you place an apple in a fridge, given enough time, that apple will rot.

The souls of the children inside of the stone were corrupted, tainted. The children inside of the stone had long since because pure evil. He couldn't sense it, but his gut told him that destroying the stone was a bad idea. That was releasing evil into the world with no way of destroying it... releasing the souls of evil children was bad, just bad.

The stone in his hand was snatched from him by Yang, and her eyes glowed red and her hair was on fire with golden flames, raising into the air.

"These stones HAVE to be destroyed! These children HAVE to be released!" Yang shouted as she palmed the stone with one hand, and gave her strongest and most angry punch with the other. The stone shattered into a dozen pieces, and it lost most of it's glow that very second.

Shadows started to come out of the broken gem, and Naruto grit his teeth.

"Yang, you idiot! You just release the souls of children that have become EVIL! Children you have been tainted by hundreds of years of evil power, and have had their resentment of the world bottled up for centuries!" Naruto shouted at her, and the gasps were heard. The shadows seemed to react to his words, his voice, they seemed to recognize who he was based on his passion. His face, they seemed to rush at him, and Naruto crossed his arms.

Not that it did him any good.

The shadows fazed through his arms, before they entered his chest. Naruto blinked in surprise, and his guard relaxed when he didn't feel anything wrong with himself.

Destroy!

Shit! He could hear their voices ringing inside of his very soul... it wasn't a child, it was every since child that had been killed by the man that had created this stone. The hatred of thousands of children tainted by the stone, and the years of pain and enslavement to the desires of others... never being able to see their family ever again.

Destroy!

Naruto fell to his knees and he grabbed the sides of his head.

The children, they couldn't take control of a human body because of the souls of this world were very different. Despite being born in this world, Naruto's soul was originally from the Chakra World, meaning that his soul was compatable with both this world and that world. The children had been able to sense this, recognizing him, and had entered his mechanical body.

He didn't even have chakra to force them out of him, and he didn't have a flesh body that he could truly control.

Destroy!

Naruto's eyes began to turn yellow against his will, and he lost the red tips in his hair. Naruto lost the concentration it took to keep his hair the two toned color. Naruto pushed Yang and Ruby away from him when they tried to come next to him.

"Damnit... Yang! When I say something... LISTEN TO ME!" Naruto shouted at his sister, who had acted going only by emotion.

If she had listened, then he would have continued and told her that when you placed a person from his world in a box for too long, and they weren't masters of their darkness like he was... then they turned evil. Even children, as pure as they were, turned evil when placed inside of a corrupt stone made from their bodies. They were tortured with the inability to move, and the terror of being trapped.

DESTROY!

It wasn't by Naruto's will that his hand started to raise, and while he was still fighting back against their complete control... his body was that of a machine. He couldn't fight them and control his body at the same time. His body needed his full concentration, or at least his ability to think clearly, to control. He could barely think with the thousands of children's voices in his head, baring down on him with the full force of their Gelel empowered might. Their rage and hate for the entire world.

"Yes... the power... The Powweeeer!" Naruto's changed voice, tainted by the voices of all if the other being inside of him, came from his mouth.

The others were pushed against the side of the boat, and Naruto covered his torso with his arms and let out a silent scream of pain.

6 arms came out of his arm, and they grew in size until each arm was over 10 feet long and the hands big enough to graso people with ease. The arms grabbed the sides of the boat when golden chains came out and wrapped around the wrists of each arm. A feral howling came out of Naruto's back, and the then more started to come out of his back... not just more, but darker... the evil coming from him was truly something to behold.

3 large skulls connected to a spine started to come out of his body, and they grew in size as a rib cage formed around his body and connected to the spine. The arms were already attached to shoulder blades, and chains wrapped around the rib cage several times. 6 large double ended battle axes were connected to the, and the skulls started to gain glowing red eyes in the middle of their empty sockects.

The skulls... were not humanoid.

They were fox skulls, each skull large enough to bite the boat in half with ease. One of the mouths were closed shut with chains, showing that Naruto had yet to unseal that face of his power. The right head was the head of rage, seeing as it seemed to be pure evil. The head in the middle seemed angry, but it was a cool anger.

His Semblence was fully evolving now, or rather, mutation thanks to the evil souls trying to corrupt Naruto's soul... they were corrupting his very Semblence with their evil taint.

The Fox-Asura Bone Avatar ripped itself out of Naruto's body, and it gained legs made out of bone that were able to stand on top of the water. The giant Asursa Fox stood at over 40 feet tall, and it roared with enough force to push the boat against the waves.

Vale was in sight by this point.

'What... is that!?' Many of Naruto's friends and allies thought when they came face to face with the giant being standing on the water.

It reached out with a single hand, before it grabbed Lumber and crushed him in it's grip. It roared loudly, and they were all forced to cover their ears or risk going deaf. The avatard grabbed Naruto, before it placed him on top of it's skull. Chains shot up, before they wrapped around Naruto's arms and legs, trying him to the middle skull.

"Aaaaaaaaaah!" Naruto shouted out, and the fox raised it's arms up, before it slammed down onto the boat. The boat split in two, and everyone was sent flying, only their aura protecting them from being killed. They splashed into the water in various spots, while Naruto let loose a primal scream of rage again. Black energy comes his body body and the third head of the avatar shatters the chains around it's mouth, all three heads roaring now in responce to Naruto's call of battle.

Destroy the world!

'NO!' Naruto shouted in his own mind, but the very act of fighting them out of his soul prevented him from stopping them from controlling his body.

Like a puppet, the skeletal asura fox moved it's body in responce to Naruto moving his arms, and it tensed it's legs, before it started to run towards the city of Vale. It ran over the water, and it was only a matter of time before it got there. Naruto was forced to watch this, but he was stuck.

He left his soul open to corruption and stop it, or he continue fighting their attempts at corrupting his soul and let them keep control over his body for the moment.

Destroy the world that killed us!

"Aaaaaaaah!" Naruto shouted out, unable to do much else but scream at this point.

Kill everything!

'Damnit! I didn't even know my Semblence could make a full body Asura!' Naruto thought as he tried to split his concentration, and he barely succeeded in stopping the movements of the skeletal asura fox. Naruto felt them pressure his soul even more, and it was harder to fight while running two seperate goals at the same time.

There were both upsides and downsides to being human, but the same could be said about being a machine.

No being was perfect, but at least with a human body it would be easier for him to resist being possessed like this.

Hate! Get out! Destroy! FREEDOM!

Naruto jerked his arm up, and the fox punched itself in the face and cracked one of it's skulls. Naruto felt pain in his own head when he did that, and the pain caused the spirits in him to shout out in pain. They were affected by his pain as well, but Naruot was forced to go back to completely defending his soul from them when they tried to take over it.

"Orgia Mode!" Naruto called out as his fans started to spin at their max speed, and the black joints on his body started to glow bright orange. Naruto could feel his abilities increase in responce to his max power mode activate. He didn't have long, but for the moment all of his systems were running at their most optimum. For a brief period of time, Naruto was able to force them out of both his mind and his soul. His body glowed as he forced the spirits out of him, and Naruto moved his arm up and he opened up his chest with it.

He could see land not very far away, so having the skeletal fox grab his body, Naruto ripped himself free of the fox avatar using it, the chains snapped. He had the fox throw himself, and the second he got a certain distance away from the bone fox it vanished into nothing. Naruto was still flying towards Vale at a high speed though. Naruto looked towards Beacon, something he could lock onto, and with his target in sight, Naruto ripped his soul orb from his chest and threw it full force towards Beacon.

Towards Ozpin's office.

His body shut down without his soul powering it, and his chest plating shut and sealed itself again. The spirits screamed as they left his body without having a soul to feed on, they simply faded away into nothing without a source to feed on. They needed a constant supply of energy.

Naruto had years of experience, he had been able to figure that out quickly and take advantage of it.

Naruto's motionless body crashed through a building, before it exited the other side of the building and smashed into the streets below, flipping over several cars and destroying another one.

His smoking body inside of a crater, just waiting for somebody to pick him up.

Not that he knew that, he was shut down.

He was at the mercy of the first person to find him.

Chapter End!
Please Leave Me Lots Of Nice Long Reviews, But No Flames Please!

The reason why Naruto needs a robot body: His Semblence
Naruto's Semblence works by giving him traits to make HIM an Asura. Naruto has 2 human arms, so his Semblence have him 4 aura arms to add up to 6 arms. It also gave him 2 extra faces, but he didn't know he could manifest them.
It works by taking what Naruto does NOT have, and giving ito him.
If Naruto lost his leg, he would form 4 arms and 1 leg.
If he lost both legs and both arms, he would form 6 aura arms and 2 aura legs.
That is why his Semblence kept him alive, it simply gave him an aura body in places he lacked an Asura's body.

Now that Naruto has NO human body period, his Semblence thinks he completely lost his body... and thus Naruto can now summon a full Asura Avatar once he learns he can do it.
