This will be purely NarutoXKurumu, no harem. Might throw in some TsukuneXMoka here and there, but anything more than that is doubtful. As far as update speeds go, I won't make any promises. It shall be updated when I feel like it. More reviews will make me more inclined to update faster though so keep that in mind. Flames shall either be ignored or used as an offering to the Firehawk. Those of you who understood that reference, here's a cookie (::) Those that didn't; play more games!

Chapter 1: Rebirth

"Naruto! Naruto, are you okay?!" shouted Yamato as he stood over the form of a teenage boy with wild blond hair. The boy grumbled something unintelligible as he rolled over to reveal his face to those nearby. Everyone gasped as they caught a glimpse of the young jinchuuriki. What once resembled whisker-like scars on his cheeks, were now much thicker and more pronounced. His spiky hair was now wilder and his canines were extended causing them to protrude slightly from his mouth giving him a rather feral look. The largest noticeable change however came when he opened his eyes to reveal pools of deep crimson with slit pupils.

"K-Kyuubi?" One of the ninja asked tentatively. The boy raised an eyebrow as he regarded the ninja that spoke.

"What the hell are you talking about, I'm Naruto. What happened?" Naruto ran his clawed fingers through his hair as he tried to make sense of the situation and remember the events leading up until now.

[Flashback]

"Stop being so damn stubborn you stupid fox, just give me your chakra!" Naruto yelled as he and the great bijuu sealed within him appeared to be having some sort of tug-of-war with a string of chakra.

"Insolent brat! I will devour you!" The enormous fox yelled as he gave a particularly hard tug and pulled the boy closer to him. They seemed to go back and forth like this for what felt like hours, but in actuality was only a few minutes. They seemed to be getting nowhere until a hard tug caused the boy to stumble and give the fox the edge he needed to pull him and his chakra closer. Regaining his footing, Naruto grit his teeth as he tugged harder causing the fox demon to growl as his nine tails thrashed about behind him violently.

This continued to drag on until something happened that nobody had expected, nor had they thought it a possibility. Somehow, the warring chakras began to collect in a single mass and pull the combatants in. Both had wide eyes as they tried to maintain their footing futilely as they were pulled into the swirling vortex of chakra. Each of them released a feral growl as flesh and fur were ripped apart and broken down by the dense chakra. Eventually, the energy began to converge and take form. The form just so happened to be that of the blond boy with some subtle, and other not-so-subtle, differences.

[Flashback End]

"I think..I merged with Kurama somehow." Naruto stated calmly as he observed the sharp claws extending from his fingers. Feeling some discomfort ffrom the way he was laying, he slowly got to his feet, bringing about more gasping, as well as fainting in one ninja's case.

"Naruto, who is Kura- oh my god!" Yamato started to ask before looking behind Naruto. Raising an eyebrow at the strange reaction, Naruto turned his head to see 9 golden tails flowing freely behind him. As if using this as a trigger to make themselves known, 2 distinctly fox-like ears revealed themselves atop his head.

"Hmmm I should probably be surprised by this, and yet it feels normal somehow. Must be due to Kurama's memories. Also, to answer the question you were about to ask Yamato, Kurama was the kyuubi's true name. That seems irrelevant now however seeing as he no longer exists." Naruto spoke with a calmness that was very unusual for him. Chalking it up to the apparent fact that he somehow merged with the great demon, Yamato went over this new information in his head. 'Well, it's not EXACTLYwhat we were going for, but perhaps this can work to our advantage.' Clearing his throat, Yamato turned back to address the blond.

"So, does this mean you have full access to the fox's chakra?" Naruto took on a thoughtful expression as he tried to figure out the best way to answer that question.

"Yes and no. I have complete access to Kurama's power-" "That's great! Let's go help the others fight the-" Yamato interrupted before stopping as Naruto raised a hand. "As I said, yes and no. I have full access..but no understanding of how to utilize it." Yamato raised an eyebrow in confusion.

"I'm afraid I don't understand. Can't you simply use it the same way you did before?" Naruto sighed as he crossed his arms with an expression that showed he was clearly annoyed with something.

"Unfortunately, no. I'm unaware if the seal was the cause of changing the form of Kurama's energy, but before he was sealed, as well as now, his power is not actually chakra. Being a demon, his power comes from a form of energy that, going by his memories, is apparently called youki. It seems to rely almost entirely on what would normally be the spiritual energy that helps create chakra. I have a basic understanding of it from his memories, but unfortunately, not enough to use it effectively. The most I can do right now is transform into my fox form and I MAY be able to use a bijuudama. That however is mere speculation at this point as, like I was saying, I do not understand this energy very well."

"Well fox's power aside, you still have your old techniques don't you? If we use those in combination with the bijuudama then-" Yamato was once again interrupted by Naruto holding up his hand.

"Unfortunately, that is not the case. I no longer contain chakra so any of my previous techniques are out of my reach. At the moment my abilities are limited to what I stated previously, superior strength, speed and reflexes, and immortality. Though those are more traits than abilities I suppose," Naruto stated casually as if being immortal was as natural as breathing.

"Wait, you're immortal?! How are you so calm about all of this?" Yamato wasn't sure how many more surprises he could handle before he had a heart attack. The boy who used to be so loud and emotional about everything had just told him he was immortal without the slightest hint of emotion showing on his face.

"Yes, I am immortal. As for how I am so calm, please keep in mind that Kurama and Naruto Uzumaki have become one being. As such, all of their memories are commonplace to me. However, I am neither Naruto Uzumaki, nor am I Kurama." Yamato was sad to hear that the happy boy he once knew was seemingly gone forever, but there was nothing that could be done about that now.

"So if you aren't Naruto anymore, who are you?" Naruto took a moment to think this over. He might not be Naruto Uzumaki anymore, but he couldn't call himself Kurama either.

"Youko. Naruto Youko. Yes, that feels appropriate." Yamato nodded in understanding and they both turned to address the others. After a brief discussion, they decided they would leave to rejoin their comrades in the fight against Madara and the masked man named Tobi.

It was a long trip back to the mainland to rejoin the others, but Yamato was happy to see some parts of the old Naruto showing through on the journey back. The boy still seemed to blatantly disregard the idea of listening to his superiors. Though, after a chuunin tried to pull rank, nobody else had any intention of trying that again. Naruto was now by far their superior in terms of power, and had no qualms with proving that fact. Yamato had somewhat expected this given the fact that the fox saw humans as little more than insects, but hadn't expected to need to stop Naruto from killing the poor kid from Kumo that tried to talk down to him.

As if to prove he had no intention of listening to anyone, Naruto had completely discarded his forehead protector and claimed he would only serve his own purposes. He had no intention of harming anyone from the Konoha, nor any other village so long as they did not provoke him, but he would not be subservient to anyone. He had also discarded his shirt and jacket claiming he did not hold his former self's obsession with the color orange and that the constricting material was a nuisance. He now wore nothing apart from black ANBU pants and the necklace from Tsunade. His footwear had also been discarded showing that his feet also sported claws instead of normal nails. Standing on the bow of the boat, a fanged grin crossed his face as they approached the coastline. He would finally be able to teach a lesson to those who had hunted his former selves.

"Are you ready, Naruto?" Turning his head toward the man who called out to him, he gave a slightly unnerving smile to the wood-user that showed his excitement for the upcoming battle.

"Just point me in the right direction and make sure everybody that wants to live stays out of the way." Naruto replied as his tails waved about excitedly.

All fighting came to a stop as a wall of wood appeared in the middle of the area separating the allied shinobi forces from the army of Zetsu clones and the remainders of the Akatsuki. Turning around, Tsunade saw several figures approaching. Seeing Yamato, she walked towards them with an expression that clearly showed her irritation.

"What the hell are you doing here, Tenzo? And where is Naruto?" She asked as she noticed that the young blond was not amidst the group. Yamato was about to answer her, but was cut off by the sound of his wall shattering. Turning around, everyone saw a boy with wild blond hair coming down just past his shoulders standing there with his 9 tails swaying violently behind him.

"Naruto Uzumaki, so good of you to join us. I must say I am quite surprised by your appearance, but thank you for bringing me the kyuubi and saving me the trouble of searching for you," called out the resurrected form of Madara Uchiha as he stood alongside the masked man known as Tobi.

"Is that really, Naruto?" Tsunade asked, but her answer came from the blond himself instead of the man she had asked.

"I'm afraid I have to disappoint you on several accounts, Madara. I am not Naruto Uzumaki, nor have I brought you anything. It gives me great pleasure to inform you that your goal is no longer possible and all of you are going to die shortly." Naruto replied with a fanged smirk as he stared down his former selves' greatest enemy. Madara narrowed his eyes. "What do you mean, boy?"

"I mean exactly what I said. You won't be alive much longer so telling you has no merit..though I suppose those behind me are curious as well so I shall explain anyway. Naruto Uzumaki and Kurama the kyuubi no longer exist. Through unforeseen circumstances, the 2 have merged to create myself, Naruto Youko. Your goal is no longer possible because you need Kurama's chakra, which no longer exists." Everyone was dumbfounded by this news. Tsunade turned to Yamato for verification and received and nod to confirm it was in fact true.

"If that's the case, I can just take your chakra instead," Madara stated as if it were obvious. The condescending laughter he received in return was not what he had expected.

"That may have been possible, if I possessed chakra." This further confused everyone apart from those that were present at the island.

"What are you talking about? Everybody possesses chakra. If you had no chakra you wouldn't be alive," Madara argued not seeing what the boy was talking about.

"Correction; every HUMAN possesses chakra. You appear to be under the mistaken impression that I am the same as you pathetic mortals," Naruto stated as he leveled a glare at Madara. Many present were disbelieving of that statement. Madara himself was having a hard time believing it, but things weren't looking to be in his favor when his sharingan revealed that he, in fact, had no chakra flowing through him.

"…What are you?" Madara asked as he tried to come up with a new plan to resurrect the juubi. Naruto's smirk turned feral as he turned to give a nod to Yamato. Seeing this, Yamato immediately told everybody to get back and form their strongest barrier. Tsunade and several others moved to protest not understanding why they would need a barrier, until they saw why.

After signaling Yamato, Naruto began his transformation. The remnants of akatsuki watched in a mixture of horror and fascination as the young blond's body began to change shape as golden fur spread across his entire body. Soon enough, they were looking at a human-sized golden fox with 9 tails. Then he began to grow.

And grow…

And grow…

By the time he was finished, he was roughly the same size as Kurama had been during the attack on Konoha. Seeing this, the allied shinobi forces immediately moved to follow the instruction of using the strongest barrier they could manage.

"Now then, I believe you had asked me what I was. To answer your question, I am the immortal king of demons, the great nine-tailed fox. But, most importantly for you, I AM YOUR DESTROYER!" Naruto spoke in a bone-chilling voice that sent shivers down everyone's spine. Once he had finished his announcement, he moved forward with immense speed and struck out at Madara with his right paw. The undead man's body was easily ripped through by the sharp claws before being knocked away by one of the massive tails.

Getting to his feet a substantial distance away, Madara frowned as his undead body repaired itself from the damage it had received. His companion however, had no such luxury. Tobi had been so fixated on the attack on Madara that he failed to notice the tail snaking its way upon him from behind. Before he had the opportunity to utilize his intangibility, he found himself with a tail protruding from his chest.

Pulling his tail back, Naruto wasted no time as he prepared his next attack. Tobi could only gasp for air as hundreds of orbs of black and red energy poured out of the fox's body. As he brought his tails in front of his face, the orbs began to collect into a single mass of dread. Once satisfied with the size, Naruto ate the orb. His body exploded outwards impossibly as smoke poured from his body.

Opening his mouth, Naruto unleashed the torrent of energy upon his enemies. The allied shinobi forces had to shield their eyes from the light of the explosion the occurred. Opening them again afterwards, they looked on in disbelief at the destruction. The, once massive, army of Zetsu clones was now nonexistent and there was absolutely no sign of Tobi.

"Damn, that's it? I guess I still can't control my youki at all," Naruto mumbled. Those who heard this were floored by the fact that this wasn't even his full potential. The lack of control however proved costly as Naruto reverted back to his normal form and collapsed to his knees panting. The fight seemed over until Madara pulled himself out of the crater that had formed as a result of the blast.

"I guess there's no other choice left," Madara said as he began a long string of handseals. Once finished, he called out "Fire Style: Armageddon!" Looking into the sky, several massive asteroids could be seen falling rapidly towards them.

"You insane son of a bitch! Not even your edo tensei body can survive that!" Naruto yelled as he tried to gather his strength.

"That's the idea. If the moon's eye plan has failed, then there's no reason to let this world survive. Every living thing shall be completely destroyed as if it never existed." Madara watched with a straight face as his attack got closer. There was no way to stop it. Looking over to see the people who were so important to his former self, Naruto couldn't push away the feeling that he had failed.

"I'm sorry," he whispered as he closed his eyes.

Finding himself unable to move, Naruto slowly opened his eyes to find himself in worse shape than he had expected. Everything below his chest had been completely destroyed as well as his left arm and shoulder. As his body slowly began regenerating what it had lost, he turned his head to see the extent of the damage from Madara's final attack. True to his word, absolutely nothing had survived. There was nothing but charred wasteland as far as he could see.

"They're all gone, huh…" Naruto whispered as he laid back and looked into the smoke-filled sky.

He was completely alone.

A/N: I randomly decided to write this in the car when I was on my way to see family so it might have a few issues here and there that I missed. Like I said at the beginning, updates will come whenever I feel like and that will be faster or slower depending on how many reviews there are. I lose my desire to write a story if it's not as popular as I'd like it to be. So with that said, leave me some nice long reviews.
