This is going to be a Naruto/Lord of the Rings Crossover but only Naruto will be added to the Lord of the Rings world. As for pairings I am not sure about that . Message me with ideas on pairing if you want them .

(Prologue)

In a massive depression in the earth lay the battered and bleeding body of the strongest ninja of all time in the elemental nations with the exception of perhaps the Rikudou Sennin himself . The man who was virtually immortal and who could bend time itself was finally defeated and killed by the combined strength of the student's of Jiraiya , Minato , Tsunade and Orochimaru . It had been a long and bitter fight where old differences had to be put aside for the achievement of a common objective . The destruction of the psychopath otherwise known as Madara Uchiha the strongest Uchiha to ever exist .

Even with their combined might they had barely scraped through to win . Madara truly was a man with no equal . A man who could bend and defy all the laws of nature . Naruto the resident seal master and one of the four people who had fought together to kill the Uchiha Patriach could not help but respect the deceased Uchiha. Madara was not just a man with a lot of hot air, he had a bite to go with his loud bark . If Madara had not been actively seeking his demise for the completion of his goals Naruto knew for a fact that he would not have dared go against the strongest Uchiha to ever live.

Oh Naruto knew that if other people found out his line of thinking they would scoff and call him a coward . The truth was that there is no cowardice in accepting the fact that there are some obstacles which you can't overcome. Naruto knew that as he was now there was no way he could singlehandedly defeat the dead Uchiha . And this is why he respected and to a certain extent even admired the deceased Uchiha . He was powerful insanely over powered at that and power deserved respect according to Naruto .

Naruto did not even remember how many different training techniques he had employed in the hopes that he would be able to match Madara . All of that was for nought as Naruto realised his progress was too slow . He knew at the rate he was going he would need another five decades at the very least to even hope to match Madara . In desperation Naruto had turned to the only thing he had which could help him match Madara . The Kyuubi a being with almost infinite chakra but no intelligence what so ever to use said chakra . Kyuubi just like all tailed demons were creatures of impulse whose natural intelligence was no more than that of the most intelligent animal that existed on the planet apart from humans . The tailed demons despite all their strength and chakra were nothing more than overgrown animals which had a very basic and simple thought process . Hunger , territory , threat, etc was the only thing they could comprehend . Even basic speech was beyond these colossal creatures . The only way these creatures communicated was through grunts and roars .

Naruto in his desperation had altered the seal holding the Kyuubi so that it would send larger amounts of Kyuubi's chakra into his chakra coils to increase his chakra reserves and regenerative abilities . Even though Naruto was a seal master he was dealing with an extraordinarily complicated seal which he had practically no prior experience with . So it was natural he would mess up . Even though the mistake was minor it had drastic consequences . The new seal instead of sending increased amounts of purified chakra into his system pumped large amounts of unpurified demonic chakra into his system continuously. This had the added effect that the demonic chakra after a while started overpowering his human chakra . To cope with the strain of this new energy his body continuously started mutating to handle the pressure from this vastly different energy source . This caused him to slowly evolve into a demonic entity . It would take a couple of years but if nothing was done soon Naruto would change into a full fledged demon with no way of reverting back into a human. In time he would even gain all the Kyuubi's chakra and energy. Not that Naruto was complaining he rather liked the idea of becoming immortal and never having to age .

This part of the deal Naruto liked . But the part Naruto did not like was the fact that along with the chakra the Kyuubi's spirit and personality were also merging with his . The seal of course made sure that his was the dominant personality while the Kyuubi's was recessive . What annoyed Naruto was even though the Kyuubi's personality was recessive it still had an impact on him . His thought process had become more primal in nature . Mind you he did not lose any intelligence on merging with Kyuubi . No what had happened was his thinking had become more like that of a cave man . He started to believe that the strong deserved to rule over the weak . That all threats to his existence needed to be removed and so on . In short he had become a lot darker and more vicious .

Naruto had done a very good job of hiding all these changes both physical and psychological from his few acquaintances and the general public of Konoha . He had taken to wearing gloves and shades to hide his claws and rapidly changing eye colour . His eyes had slowly started becoming more and more slitted and their colour had changed from the deep blue into violet . He knew in the coming months his eyes would become slitted like a cat's and colour would change into bloody red exactly like the Kyuubi's eyes had been. Naruto had gone so far as to even stop socialising with the small number of people he liked. In this way he hoped that no one would notice his changes and sudden shift in his personality . He hoped he would be able to continue to keep his secret safe in the future .

"Finally it is over" said Sasuke Uchiha .He was being supported by his pink haired ex team mate Sakura Haruno . Too much use of his Mangekyo Sharingan had left him dizzy and his vision hazy .

"No, it is not over yet there is still one other thing left to do" said Naruto his eyes hardening while his mouth clenched .

Sasuke and Sakura turned towards their third team mate with a curious look .

Before anyone could ask what he meant by that Naruto pulled out two kunai from inside his jacket sleeves faster than anyone could see and plunged them into his two ex-team mates chests and straight into their hearts .

Shock was the only thing that could be registered by the two dying Ninja .

"Why" was all that Sasuke managed to wheeze out before dying .

"Naruto have you completely lost your mind" screamed Kakashi Hatake the Jounnin sensei of their Gennin team . Kakashi had been paralysed with shock by the unforeseen betrayal of his student .

Naruto started to walk slowly towards where Kakashi was laying on the ground trying to recover from chakra exhaustion .

"No I have not lost my mind sensei . The Mangekyo Sharingan of an Uchiha can control and restrain the power of the tailed beasts . This also means that Sasuke could control me . I couldn't allow that" said Naruto in a dead tone . His facial expression showing not a trace of emotion .

After a small pause Naruto continued " Especially after Sasuke proved himself untrustworthy on multiple occasions in the past. Yours and Sakura's death is regrettable but I can't possibly allow word of my actions to get back to Konoha . This is nothing personal but I simply won't allow any threat to my existence to remain ."

Kakashi looked down . The pain he felt was too much to bear . When had Naruto fallen into the darkness Kakashi wondered . Had he finally snapped from all the strain put on him due to his being the Kyuubi jailor wondered Kakashi . He wondered if things would have been different if he had spent more time with his knuckle headed student . Got him to open up more . Perhaps if he had helped Naruto to see the world and helped him realise that there was more to life than training and missions . He realised how lonely an existence Naruto led . With no friends or family only his own thoughts to keep him company . Kakashi knew that there were barely a handful of people who even dared to socialise with the demon container . Most didn't want anything to do with him while the rest were driven away by the social stigma of being associated with Naruto . Had he the legendary copy cat Kakashi been so badly fooled by his student's false laughs and smiles that he did not even realise when madness had overtaken him . What saddened Kakashi was that he like the other members of his team had not even bothered to get to know Naruto outside of missions . They had always been too busy with their own lives to spare some thought for their other team mate . After some thinking Kakashi realised with some shock that it was quite a miracle that such a thing hadn't happened long ago . After all man is a social animal . He is meant to love and be loved by others . With no one willing to love him it was only natural that Naruto would grow to love only himself . It was ironically funny in a sick kind of way thought Kakashi . When he had been twelve years old Naruto had fought and defeated Gaara of the Desert who had been a person who loved only himself and had no one who cared for him . On defeating Gaara, Naruto had preached about the importance of love and bonds . Five years later Gaara had the love and respect of the whole sand village while Naruto had grown to love only himself . It was strange how life could throw these curve balls . It seemed that in life Naruto had gotten the shortest stick there was .

Kakashi shook himself . There was no point in crying over spilt milk . What could or possibly would have been had no effect on the here and now . He had to stop Naruto now so that he did not become a threat to every person alive .

Kakashi took all his remaining chakra and pushed it into his Sharingan eye . When he opened his left eye it had taken the shape of his Mangekyo Sharingan .

Naruto stopped walking and tilted his head to the side in a gesture of curiosity and asked "Who are you trying to fool sensei ? You don't have any energy to stand up . There is no way you could use your Sharingan let alone your Mangekyo Sharingan at this point of time . You are just wasting chakra."

Not giving a response Kakashi gathered every last ounce of chakra left in his being and prepared to use his final attack . He knew that that he was not going to survive this . After he used this attack he would have nothing left . Not even a little chakra would be left . He was going to die but he had every intention of taking Naruto with him .

Naruto seeing that Kakashi was not turning off and covering his Sharingan thought that this might not be a bluff after all . He quickly took out his kunai and rushed to deliver the killing blow to his sensei .But before he got between a dozen paces of his sensei's position a massive tear opened in the fabric of reality two paces behind Naruto which started pulling everything around it towards the tear . Naruto's surprise worked against him and thus he was unable to ground himself with chakra in time and was pulled into the tear along with a lot of debris . The tear in the reality closed as Kakashi no longer had the chakra left to sustain it .

"Finally it is over" was the last thing Kakashi spoke before dying .

To this day no one in the elemental nations ever found out what actually transpired that day.

AN: I am stopping here because I want to refresh my knowledge of Lord of the Rings .I read the books four years ago so it is natural I might have forgotten something . Anyways what I really want you people to do is tell me which timeline should Naruto appear in . I personally am leaning for after Sauron's death . I will have to do many alterations to the normal plot line so that the story will work .
