Okay, some will most likely see the similarities between this work and MaelstromBankai's story by the name of Demon King of Fairy Tail. In truth the original idea is his, and I am using it with his permission. I was trying to think of a unique reason to make Naruto immortal and I came across his work a while ago and was enamored by his skill and unique ideas.

I became interested in what would happen if he were to stay in his dimension and live on until he came upon a future timeline. Now I'm having trouble deciding which timeline I should go with so I've decided to leave it up to a poll. The details are at the end.

By the way, some of the things happening in the story may bear resemblances to other fics which considering there are over a thousand of these...not my fault. I'm just saying I'm not copying anyone and if I use something specifically from someone's story I will ask if it's alright with them and give them credit in the chapter it happens in.

With that in mind, I give you: The Immortal.

On what was once land filled with trees and lush vegetation there was reduced to a barren scar. Two men stood side-by-side staring with disinterest at the throng of allied shinobi that stood before them.

The first man hardly resembled a human in appearance at all. Hair as white as snow and his skin a light gray, protrusions from his back and shoulders resembled the collar and coattails of a haori, two horns extended from his forehead, the one on his right slightly longer than that on the left. Six markings resembling magatama were displayed on his chest resembling a necklace and around his back there was a halo of eight black orbs. Another orb hovered behind his left hand and in his right he clutched a shakujo with six rings that jingled whenever he moved or a soft breeze would brush against them.

His right side was covered in a pattern that resembled the scales of a reptile, further adding to his inhuman look. The iris of his right eye was colored a crimson red, three black tomoe surrounding the black pupil like the blades of a pinwheel. His entire left eye was purple, concentric circles surrounding the small pupil like ripples on the surface of a pool.

His name was Obito Uchiha, the man to single-handedly declare war on the Elemental Nations. He had only recently become the host of the Juubi and learned to control his powers and had been doing the largest portion of the recent fighting against the greatest warriors of Konohagakure, the resurrected kages of old along with Naruto Uzumaki, jinchuuriki of Kurama, the Kyuubi, and Sasuke Uchiha, Naruto's former teammate and once a traitor of the village.

At his side stood a man that once lived during the founding of the village they now faced. A tall, fair-skinned man with spiky, black hair grown to waist length in the back with shoulder-length bangs framing his face, his right eye hidden by the black curtain. While his body appeared to be relatively young, prominent creases had developed under each of his eyes that betrayed the aging of a warrior that had spent most of his life locked in an endless war.

His clothing closely resembled the armor of the samurai of Tetsu no Kuni, red plating with his back left open to reveal the symbol of a red and white fan embroidered into the black body suit he wore underneath. In his right hand he held the bandage-wrapped handle of a large crimson gunbai with black trim and decorated with the same pattern as his and Obito's eyes.

He was Madara Uchiha, one of the founders of Konohagakure and the old rival of the Shodaime Hokage, Hashirama Senju.

Directly in front of the duo stood Naruto without his chakra cloak, Sasuke and Tobirama, Hashirama's younger brother at his side. His father, Minato, had just used his fuinjutsu to merge the yin chakra of Kurama he had sealed into himself the day of his death and the yang chakra in his son to form the completed Kurama within the seal on Naruto's body and it was taking a moment for the bijuu to fully settle his chakra.

"Do you still consider us to be weaklings?" the boy asked, his eyes shifting once more to display the marks signify his usage of the sage arts.

Obito simply stepped forward, preparing to engage the group yet again, never noticing that his teacher had begun forming the handseals for a jutsu as he did so. The jutsu was one he had developed with his brother, Izuna, during their battles in the war between his clan and the Senju as a way to restore his eyesight if he had not perished on the battlefield soon after. Its concept had been to allow the wielder to selectively assimilate certain traits of enemy shinobi that he would find desirable into his own body and had been the only thing that had kept him alive after his battle with Hashirama that had created the place now referred to as the Valley of the End. At least until he managed to unlock the Rinnegan and gained access to the body of the original Juubi.

Now he was planning to utilize his jutsu by assimilating the final remaining jinchuuriki in existence, Naruto and Killer Bee, host of the eight-tailed bijuu, Gyuki. He still required the final two if he wished to complete the Juubi's revival as he had no intention of becoming the jinchuuriki of an incomplete bijuu.

He was just forming the last seals when he was forced to kick away a random shinobi thought had been attempting to place a seal tag on his back. 'Fool,' he thought. 'Did they forget that I am a sensor?'

Disregarding the newly dead corpse of the would-be hero the resurrected Uchiha clan head resumed forming his jutsu. However, due to his momentary lapse in concentration he was unable to realize that he had formed some of the seals incorrectly, thus changing the focal point of the jutsu.

The shinobi were about to launch another offensive against the new incomplete jinchuuriki when Madara chose that moment to speak. "Ninpo: Douka no Jutsu."

As the words left his lips strings of chakra were sent flying out toward the allied shinobi but the moment he felt his body become wracked with pain he knew something was wrong. Obito sank to his knees, clawing at his chest in pain while all around them the shinobi were dropping to the ground with cries of anguish.

"What's….going on?" the resurrected clan head growled out through teeth grinding in pain as he fought to stay standing. His eyes lifted to observe the others around him and that's when he saw something that would have made his blood run cold if he were still alive.

Naruto Uzumaki was standing alone, clutching his head in his hands as he screamed his agony to the dark heavens above. The vast net of chakra strings, including the ones extending from the Uchiha's own chest were all entangling themselves around his body.

'No,' he thought. 'Why is he the one absorbing them?'

Unable to hear Madara's mental ranting, Naruto was crying out mentally to his partner. 'Kurama! What the hell is going on?'

'I don't know,' the fox roared, he too was suffering from the pain of the jutsu. Memories were rushing into both of their minds, making them feel overloaded with information. Kurama forced as much of his chakra through the seal as he could, hoping to jumpstart his host's healing properties in order to stop what was happening only to make it gain in speed. Soon the pain became unbearable and Naruto found his vision swallowed by darkness.

"Naruto," his vision flickered and he opened his eyes to find himself surrounded once again by the bijuu and their jinchuuriki, although now they had been joined by the last member of the group, Shukaku the sand spirit. "Naruto, you need to listen there isn't much time."

The boy turned to Son Goku, the four-tailed monkey and the first to tell him his name. "What's going on Son?"

"Whatever it was that Madara did it's making you the focal point of a massive jutsu," he answered, his voice rumbling like a landslide. "All of the shinobi forces, including Madara and Obito are being absorbed into your body as we speak."

"That includes the Juubi as well," Matatabi, the two-tailed cat said. "Kurama is fighting to keep you stable right now so we can't pull him in to talk with you but unless you're there to exert your will you'll be swallowed by the mixture and become something else, someone else."

"Wait, if the Juubi is being absorbed what's gonna happen to all of you?"

"We intend to use our own will to influence the jutsu," Gyuki said, Bee perched on his nose like he tended to do quite often. "While all of the humans merge with you, we are going to merge with Kurama. He is the strongest of us and he should be the dominant personality when it's over."

"But then won't you guys disappear?"

"We're not sure," Son said, shifting on his feet. "It could be that we'll make up different parts of the old fox's personality or you may even be able to temporarily split us up long enough for a battle. There's also the chance you'll just absorb all of us and become a biju in human form."

"We can't really predict what will happen," Isobu commented. "All we really know is that even we cannot escape this technique."

Naruto sighed and sat down, crossing his legs as if he were preparing to meditate. "I'm sorry I couldn't keep my promise."

"They don't blame you," Han said, his deep voice fitting perfectly with his large armored frame. "None of us do. Nobody could have predicted this, we do appreciate what you have done for us in trying to rescue us. Now let us help you."

The seven jinchuuriki all dropped to the ground and approached the last living member of their group. As Naruto stood to meet them each one placed one of their hands on his shoulders, Fuu and Yugito each grabbing one of his hands.

"We have each learned to utilize our bijuu's powers," Roshi explained when the blond looked at them curiously. "By absorbing the parts of us that remain with our partners you will retain our knowledge and be better able to use all their powers as well."

"That's right," Fu chirped. "All their powers had to come from somewhere so the big bad one probably had all the same abilities as well."

Naruto smiled and nodded as the place where their palms came in contact with him began to glow with a soft white light. Strings of chakra grew from his body, wrapping around the jinchuuriki surrounding him and pulling them closer. Before he returned to the conscious world he heard Son give one last bellow. "Good luck kid!" he yelled. "Give 'em hell for us!"

Naruto's eyes snapped open and he found that most of the shinobi had already been absorbed. He felt countless memories and personalities pressing in on him and had to grit his teeth to keep from blacking out again. Grunting with the effort he forced himself to stand once more and spread his arms wide1. "Ain't no stupid jutsu gonna take me down!" he yelled. "I'm number one and I'll stay that way!"

'Kit, what are you doing?'

'Kurama, no matter what happens I need you try and help me stay in control.'

'What are you talking about?'

'When I blacked out I met with the bijuu again. They said whatever that jackass did backfired and now we're absorbing everyone, including the Juubi. I need you to help me regulate this so I stay in control.'

'….Alright, but you better pull through with this kit. So help me if you disappear and get replaced my Madara or his little butt buddy I swear I will personally hunt you down to whatever part of the afterlife you go to and kick your scrawny ass before dragging you back here to take control.'

'Wouldn't have it any other way,' he responded, smiling despite the pain. 'Now let's get started.'

The blonde sage closed his eyes and relaxed his body, leaving only enough tension to stay standing. The chakra wrapping around him began to slowly solidify, taking the same appearance as the white version of Zetsu. The white solid chakra dripped off of his arms and fell to the ground, pooling around his feet and crawling up his legs. Within minutes his entire frame was covered and the ooze began to swell outwards, growing thicker and harder as the seconds ticked by.

When the last threads faded into nothing, where Naruto had stood was a white cocoon of pure chakra that squirmed and bubbled. The smooth shell would randomly shift, a tentacle now and then nearly breaking the tension of the surface to escape but drawing back before it could fully breach. Eventually it stopped altogether, hardening to the point of a solid block of granite.

How long did it take for something to happen, no person would ever know. There was none alive to keep track, but if anyone were to ask about that day, no matter where it was they would all say the same thing. They would say it was like the entire Earth had grown still. Like nature itself was waiting to see the outcome of something that would later decide whether or not it would continue to exist.

Suddenly five figures dropped into the cleared battleground. It was the kages, restored by Karin Uzumaki under Orochimaru's orders. Onoki let his gaze travel across the area, taking note of the discarded clothing scattered about as if the shinobi and kunoichi had simply discarded them and walked away. Finally they rested on the solid white boulder that stood alone in the space.

Curiosity getting the better of the old man he used his flight ability to hover closer and inspect it up close. Finding no crack or deformity in its surface he reached out to touch it only for a another hand to grab his wrist before his fingers could brush against it.

"I wouldn't do that if I were you," the familiar voice of the white half of Zetsu spoke.

Onoki quickly jumped back, hands ready to unleash a technique should the artificial human choose to act aggressively. However he simply held his hands up in the universal signal of surrender.

"What are you doing here creature?" the Raikage demanded.

Zetsu lowered his hands and grinned cheekily at the shinobi and kunoichi that stood before him. "I was just warning shorty here that he might not want to touch the rock."

"And why not?" Onoki inquired, choosing to ignore the slight against him. The white clone of the Shodaime Hokage simply smiled and explained what had happened. Needless to say the kages were left speechless at what Madara had done.

"So Naruto is trapped in their huh?" E growled. "Well let's break him out of there."

"It's not that simple you muscle-bound fool." The group turned to see the black half of Zetsu rise from the ground. "The jutsu Madara used is designed to assimilate his targets into his own body, granting him the same powers and knowledge as them. When the jutsu activated he intended to absorb Obito and the two remaining jinchuuriki. Instead the jutsu has gone awry and now Naruto Uzumaki is now the host of the entire force of the Shinobi Alliance."

"Don't forget the Juubi either," the white half chirped, giggling softly to himself. "Little Naruto has all that swimming in his head...I wonder who'll be on top when he wakes up?"

"You still haven't explained why we cannot touch this thing," Gaara said, cutting off the black half from making his usual biting retort. "What prevents us from coming into contact with it?"

"The jutsu is still in effect."

"How do you know that?"

"I am Madara's will. A clone made with his memories and knowledge, including the technique he created with the intent to save his brother long ago." He paused long enough to let that information sink in and then continued with his explanation. "When the jutsu activates, a growth similar to the spore clones my white half uses covers a certain amount of the caster's body. The more the caster is absorbing from the target the larger and more compact the growth is."

"Eventually the growth is absorbed into the skin, signifying the end of the technique. A normal absorption is the genetic material required to assimilate a bloodline which is actually rather small and lasts a few minutes at maximum. Naruto Uzumaki has absorbed almost the entire shinobi alliance. A full body, all the muscle mass, ligaments, genetic code, memories and personalities depending on its size could take days or even weeks depending on the complexity of the subject."

"Add to that the entire Juubi along with the nine bijuu locked inside of it and you've got one hell of a long wait," Tsunade finished for him, biting her lip in thought. "In the end he will be practically a god but considering the facts and add on that we've lost all but the low-ranking shinobi from our villages and the medical shinobi and we've suffered a devastating loss."

E nodded, crossing his arms as he pondered their predicament. "We won't be able to keep our villages up the way they are," he said, garnering the attention of his fellow kages. "The Daimyos will not wait for us to regain our strength. They'll move their soldiers into action and start taking over."

Onoki sighed. "We'll be reduced to little more than party favors and old relics in a matter of a couple of years. Still, what can we do to prevent it?"

"We could take our shinobi and band together," Gaara said.

"But where would be go?" Mei asked.

"I think I may be able to help with that little problem." Everyone turned to see Orochimaru standing nearby, his arms crossed and lips curled in his usual confident smirk. "After all, my village is the only one that's actually...a hidden village."

"So you would offer us the use of your facilities just like that?" Sand began to trail around their feet like snakes as Gaara addressed the former member of the sannin. "What do you gain out of this?"

"Well I would appreciate if somebody would break my little successor out of the genjutsu a certain Uchiha placed him in. I'll even throw in my cute former apprentice and the Mokuton experiment."

Tsunade narrowed her eyes. She would never trust her old teammate again, but they needed everyone they could possibly get in order to keep their way of life alive. Sighing she agreed to the terms to which the man responded by summoning a giant snake with orders to take the kages to Kabuto's former hiding place. Gaara took a moment to wrap an giant sphere of sand around the boulder holding his oldest friend which he made follow them to the cave.

There Tsunade freed Kabuto from his dream of endless combat, separated Yamato from the tree he'd been forcefully merged with and cured the paralysis holding Anko in place. Once they were ready she then created two shadow clones with orders to retrieve everyone from the medical tents and move them into cover until she contacted them and they were off.

"My bases are a temporary solution Tsunade," Orochimaru said as they walked out of the cave, Naruto's sphere still floating behind them. "These shinobi will require a more protected place soon."

"Would you happen to have any ideas," Mei asked, her eyes never leaving the trees as she scanned for a possible ambush.

"As a matter of fact I do. Uzushiogakure to be exact."

"The home of the Uzumaki clan?" Onoki scoffed. "The place is in ruins, what good would it do to go there?"

"Well, I have been studying fuinjutsu quite avidly since my former sensei managed to seal my arms away as has Kabuto. Add to the fact that I have the five number one shinobi from each of the five great nations I'm sure we can come up with something."

The old man grunted but nodded in understanding. The Uzumaki homeland, how ironic the place his village along with Kiri and Kumo had fought so hard to destroy would become their chance at survival. If only his predecessor could see him now.

Seeing the others follow the Tsuchikage's example, the snake sannin summoned another serpent with orders to take them to Uzushiogakure. They traveled through the night and into the next morning just to reach the coast and didn't reach the island nation itself until late that afternoon.

"We'll need to get rid of the ruins first," E said. He glanced at his traveling companions and couldn't help the small smirk his lips were forming. "Care to see who the best at causing collateral damage is?"

His fellow village leaders simply grinned before they all vanished in a shunshin. For the next several hours all Yamato, Anko and Kabuto could see was an endless dust cloud with the occasional glimpse of the kages in action. E flying through the air shrouded in lightning, demolishing stone and wood with ease, Tsunade kicking entire buildings over with a single kick, Mei melting great stretches of property with her lava and corrosive mist with Onoki lifting massive chunks of earth and letting them drop. Among all the chaos was Gaara, his sand neatly gathering and piling separate piles of carved stone and wood for later use. Although let it be said that many a pile of wreckage was engulfed and ground down by the former jinchuuriki of Shukaku.

When most of the area was clear, Gaara moved Naruto's prison to the center of the island, beneath where the tower of the leader of the Uzumaki clan was located. There Onoki used his mastery of Doton jutsu to create a stone sphere as big as two-story house with the prison inside of it. Then Orochimaru and Kabuto began to meticulously cover the entirety of the construct in a complex sealing array designed.

"What's this meant to do exactly," Mei questioned the sannin as he added the last brush strokes to the seal and stowing away his equipment.

He glanced at her momentarily and turned his eyes back to the sphere. "The main purpose of the array is to gather chakra from nature and use it to reinforce the dome from the outside. Zetsu should still be able to phase through it, leaving him the ability to check on the stages of Naruto's recovery and should we come across anything that should be stored there then he can drop it off during a visit."

"Everything is ready Orochimaru-sama," Kabuto called. The sannin nodded in acknowledgment and turned to Gaara who clapped his hands together and called upon his control over sand to bury the tomb over a mile underground. He then used the sand to pull up great pieces of stone and put them together beneath him, leaving a circular area of sand as evidence of what was buried beneath.

"He is safe now," he said and then turned to Yamato. "Erect the tower."

The Anbu officer nodded and quickly went through a small series of handsigns, ending with both hands clasped tightly before slamming them down on the ground. "Mokuton: Shichuka no Jutsu!"

Wooden planks erupted from the earth in front of him, weaving together to form a tower similar to the mansion where the kage of each village lived. Instead for the symbol of one of the elements, the tower was marked with the symbol of the Alliance. The kanji that stood for shinobi.

"One down and a whole village to go," Tsunade quipped, chuckling at the downcast expression on the jonin's face. "But don't worry, one of my clones is on its way to Nami no Kuni to order supplies and the others are leading any refugees back here."

"Then what's next Hokage-sama," Anko asked. The six kage level shinobi sighed and turned to walk away.

"Now, we return to our villages and get our people out of there before the Daimyos can make their move," Onoki growled. The others could have sworn they heard him mutter something about stubborn old coots who couldn't mind their own business but wisely chose not to point out the irony of the moment.

"Anko, I need you and Yamato to stay here. Keep an eye on things and start looking for anything salvageable after our little...ground work," the female member of the sannin ordered. Said kunoichi and shinobi nodded and set about their task while the six leaders prepared to make the long journey back to their villages. All the while praying their hero would beat the odds again and wake up.

Unfortunately that was not to be...not in their lifetime at least.
