Hidden Genes

Summary: There is a type of jutsu only one shinobi could use,the Shodaime became famous for it being impossible for anyone who doesn't have his DNA, and even then it was rare. Sharingan is an Uchiha doujutsu,so no one can have it unless an eye is given, so why does the Kyuubi vessel have both?Why does he move like the Yondaime?

Naruto, much to his own confusion, arrived just in time to save a terrified Sasuke from the snake like man who seemed to be stalking the Uchiha like a predator. When the older boy looked up to him, his eyes were full of fright and an unbearable pain, his left hand clutching his right shoulder, from where Naruto could smell some blood slowly dripping from some wound. The strange churning of Sasuke's chakra that he could feel made him worried and curious enough to ponder risking the last secret he kept from Sasuke being found out just to see what was tormenting his friend, but the older ninja attacking Team 7 never gave him a chance as he attacked the newly arrived blond.

From the corner of his eye as he let Kurama's battle instinct take over his body and he easily avoided the man's attacks, Naruto saw Sakura trying to drag Sasuke away while said preteen seemed to be crippled under the wound to his shoulder. Naruto worried that the freak had managed to do some serious muscle damage but he knew he won't be given a chance to check until much later, if he manages to chase this freak away. He seemed unhealthily fixated on Sasuke when Naruto had arrived but that fixation - or a good portion of it - had now shifted to him and Naruto knew he was in for a nasty fight. One where he will definitely need some of the techniques he had learned in secret if he wanted to get out of this damned forest alive.

"Katon: Gokakyu no Jutsu!" Naruto finally gave in and used the fire technique when the Kusagakure ninja got too close and he was unable to dodge him fast enough. He rarely used fire techniques because they weren't in his chakra nature but his often use of Sharingan had enabled him to use them as though he were a real Uchiha. The fact that his chakra nature was actually wind, if Kurama is to be believed (and he is), definitely helped in making most of those techniques far deadlier than if someone else who didn't have fire natured chakra were to use them, the natural order of things helping the fire along. Naruto might be better suited for wind (his chakra nature), water and earth (due to his Mokuton) but he could still use fire pretty damn well, which the freak that had attacked them learned the hard way, if his hissing was anything to go by. He really was like a snake.

When he emerged from the fire, half of his face seemed to be peeling off, making the Uzumaki shudder. Just what the fuck was wrong with this guy? And his eyes ... they were golden and so reptilian like that Naruto froze for a moment and nearly got pierced by the Shuriken Kage Bunshin no Jutsu that the man threw at him, had it not been for Kurama's quick reflexes, the Kyuubi propelling him further away from the snake man. The face that was now showing from beneath the first layer of skin was almost deathly pale and the forehead protector was slashed, obviously from the struggle Sasuke had put up to keep their scroll until the creep did whatever he did, but the mark on the hitai-ate was a note, not the symbol for Grass.

"Kukukukuku." The man chuckled as Naruto landed on a tree ten feet away from him. A three foot tongue slipped out of his mouth in a very snake-like fashion and Naruto shuddered at the disgusting sight while alarm bells suddenly started ringing in his head from Kurama's place in his mind space. "The same technique getting me twice." A hand came up and yanked off the first layer of skin, making Naruto and Sakura blench from where they were watching, the kunoichi now supporting a barely conscious Sasuke. "How amusing. It seems I've underestimated Konoha's two most famous orphans."

Naruto, get the fuck out of there! He nearly jumped when Kurama yelled inside his head. The fox had never sounded so worried and on edge as he did now. The blond Jinchuuriki instantly knew something was not right.

'You know who he is,' it was a statement, not a question, but Kurama still replied, all the while pumping enormous amounts of chakra into his host.

He's Orochimaru of the three Legendary Sannin. He defected some ten or nine years ago, if memory serves. You were too young to know what the adults were talking about back then but I remember them saying he ran away after the Hokage found one of his underground labs with inhumane experiments going on in search of immortality. The Kyuubi explained, never taking off his senses - and his eyes, through Naruto's, which were now a bloody red - from the Snake Sannin. Orochimaru was not an opponent to be underestimated. Naruto, remember me telling you not to use any of your Kekkei Genkai?

'Yeah,' the boy uneasily answered, already reaching for both his and Kurama's gifted chakra, having a bad feeling he knew where this was going.

Fuck that right now. If we want to get out of this alive, you're going to need to use those in order to survive. Just the fact that Kurama was condoning the use of his Kekkei Genkai around other ninja was enough for Naruto to know they were possibly in some deep shit and that there was to be no holding back if they wanted to stay alive. It had helped them in the past, when some bloodthirsty, religious lunatics had invaded Konoha's territory and they had somehow stumbled upon Naruto's tree in the forest. Had he held back then when Kurama told him to go all out, they would have been one dead Jinchuuriki and one dead biju pair.

'Rodger that, dattebayo.' The blond replied, once more focusing fully on their enemy. In his head, a few minutes have passed, but in the real world, not even a full second has so Orochimaru had not had all that much time to do anything, even if he were hailed as a legendary ninja genius. "You're not here for our scroll. What do you want?"

Orochimaru chuckled at the blond's observation, bringing a hand to run it through his hair as he flipped it over his shoulder and out of his way, a sign he was still very much planning on continuing this fight. "You're correct, bozu. I'm here for something much more valuable."

Naruto's eyes narrowed as his mind raced for what the man could possibly go through all that hassle for. He looked over to his teammates and it dawned on him as soon as he saw Sasuke and his crippled state. Not even bothering to suppress his anger, Naruto let red chakra start boiling out of him. ''You're here because of Sasuke.''

''Very good, Naruto-kun. Perhaps you're smarter than people give you credit for.'' The Sannin mocked, chuckling in that creepy way of his once again, making Naruto grit his teeth as he was covered in the first level of the Kyuubi chakra cloak. ''Although, you would be an equally desirable prize. Still, you're just a bother to me right now. I will come for you later. For now, be a good boy and give Sasuke-kun over to me.''

Throwing one more glance at his friends - Sasuke was obviously out cold but his body was twitching in a worrying way and Sakura was trying to calm him down as it appeared he was having a seizure of some kind, so she wasn't paying attention to the soon-to-start fight - Naruto made his decision. Using the speed Kurama provided him with, Naruto charged at Orochimaru, allowing his eyes to gain the three tomoe and hoping he will be fast enough to be a blur to Orochimaru so he won't notice that his eyes weren't red just because of Kurama's influence.

The first hit landed spectacularly, Orochimaru obviously not expecting him to have such speed at his disposal so young and untalented as far as the world was concerned, and it sent the man flying through twenty trees and far away from the rest of Team 7, which had been Naruto's first intention. The second Orochimaru tried to dodge, but experienced shinobi he might be, he was not alive long enough to have ever seen Uchiha Madara fight so he stood no chance against those few twisting moves Naruto knew how to do, and with Kurama's chakra enhancing all his muscles, his flexibility was up to par with what would be needed for some of the shit Madara used to be able to do. Even when Orochimaru tried to strike back, Naruto's Sharingan allowed him to read his movements even before he tried to make them so he easily dodged or countered before they could land, obviously frustrating the Sannin that a kid was beating him this soundly.

When he got his bearings back together enough to summon chakra into his own feet for speed, Naruto decided he wasn't going to allow that, briefly putting his hands together in the all too familiar prayer-like position and allowed his chakra to seep into the tree he and Orochimaru were fighting for. His chakra easily pushed into the tree's bark, his Mokuton easing the way and changing the tree's texture to his will. When Orochimaru tried to effortlessly slide across the surface of the bark, he was met with intense friction that slowed him down significantly, so he had to spend more chakra on speed, where Naruto then allowed the bark to become as smooth as if though it were a new branch, which made Oreochimaru slide straight over it like a beginner. Naruto allowed himself a brief moment to enter his mind space just to laugh his head off with Kurama for a couple of minutes in there before returning to the real world not a blink later.

Aggravated didn't even begin to explain what Orochimaru was feeling and he quickly put his hands together, summoning three giant snakes to attack the Jinchuuriki. Naruto glared at the creatures, putting his won hands together and creating ten Kage Bunshin for each snake while he himself charged at the summoner of the creatures. The clones went for the snakes and Orochimaru saw Naruto coming, quickly making a new set of hand seals.

''Fūton: Daitoppa!'' A great ball of wind spiraled towards Naruto at great speed and he crossed his arms over his neck and head to protect them while the first tail of his chakra cloak sprung out at his behind, wrapping around him to shield him from the damage the attack could cause. Seeing that his opponent couldn't see him due to shielding his face, Orochimaru quickly did another series of hand seals for his second jutsu. ''Katon: Gokakyu no Jutsu!''

Naruto still felt the rise in chakra before the jutsu was preformed and recognized the heat that was coming out of Orochimaru's chakra, so he was ready, thanking Kurama for drilling into him the ability to recognize chakra nature signatures as his first sensor's training lesson. ''Suiton: Teppadama!'' The two attacks collided, filling the part of the forest they were fighting in with mist and steam. Allowing himself the risk of upping the Sharingan into its Mangekyo stage, Naruto searched through the clearing for any sign of Orochimaru. He easily spotted his chakra in the bark of the tree, using what Naruto was sure was Doton: Moguragakure no Jutsu to hide from him and try to attack him unawares. Naruto was very disappointed that he hadn't seen the signs needed for the technique. It would be very useful.

Still, Orochimaru had made a great mistake of going into the trees. Trees were Naruto's domain and he was going to show that to Orochimaru. Crouching down on his branch and channeling his chakra into the tree, Naruto made the wood all around Orochimaru become so hard that not even the strongest jutsu would be able to break it, not even that lightning jutsu Kakashi-sensei had used in the Land of Waves when he had almost killed Haku.

But the part of the branch where Orochimaru precisely was was still of the same density and strength, very easy for a chakra enhanced punch to break through, as Naruto soon demonstrated to the Snake Sannin, almost breaking Orochimaru's skull when he punched him. In fact, Orochimaru would have been dead had he not used those strange regeneration abilities he has.

Naruto allowed his eyes to fade back to normal - well, if you can call a split pupil normal. Simply put, he just deactivated his Sharingan since he was standing still and had the risk of Orochimaru seeing the should-be-Uchiha-only doujutsu. ''Had enough yet?'' He taunted the other shinobi, keeping his senses wide open in case Orochimaru tried anything sneaky, like he no doubt would.

The snake only glared at him. ''Don't get so haughty, you little rat. I admit, you are stronger than I expected you to be, but that doesn't say much, now does it. You'll still die here, today. And I'll make sure it is as gruesome and as painful as I can make it.''

Sharp, red eyes glared down at his opponent, the blond huffing and crossing his arms in the manner Kurama's memories always showed him Madara do. Man, but that guy was cool and Naruto very much liked some of his gestures, even if he turned out kind of evil in the end. Naruto had no plan in following in his footsteps, but the only other option he had from Konoha's founders was Hashirama and despite being hailed as the God of Shinobi and the best ninja up to date, that guy was so uncool it hurt to watch Kurama's memories of the man. So, yeah, Madara's gestures. It seemed to sure as hell irritate Orochimaru with how superior it made him look.

He hmphed. ''As if you could kill me that easily.'' He very much enjoyed the barely surpassed growl that left Oorchimaru's mouth and Naruto fought down a grin. ''Face it, Oorchimaru. A genin is whipping your ass. You're obviously not as great as you claim to be. Maybe old age has finally gotten to you. It kind of tends to happen.''

Surprisingly enough, Orochimaru smirked at this, a very creepy smirk. It sent chills down Naruto's back and he allowed a second tail to manifest just in case. The fact that Kurama was currently suggesting a third, too, didn't reassure him.

''You're right, Naruto-kun. But that is, after all, why I have come here today.'' The blond cocked his head to the side inquisitively, not understanding what he meant. Orochimaru just chuckled in that sick manner again, making Naruto's stomach churn. ''This vessel has become inadequate and I need a new one. I am so lucky to have already found one. It is now only a matter of time.''

The Uzumaki was very disturbed by the grin that split the Sannin's face not a second later. ''What-?'' But his question was cut off when, suddenly, Oorhcimaru opened his mouth so wide it would have cracked a normal person's jaw and a sword flew right out of his mouth, extending and extending until it hit Naruto right where his heart was. The chakra cloak - bless it and Kurama - slowed the sword's way towards his skin and heart and Naruto's eyes widened.

'W-what?!' That had never happened before. The cloak always protected him! 'What's going on?!'

Shit, it must be a Kusanagi Sword! Kurama grumbled, pushing more chakra into Naruto, the third tail forming. That thing can pierce almost anything! You need to manifest more tails!

'We can't!' The blond protested, allowing his Sharingan to activate instead since he was now a hundred or so feet above the forest, more than far enough for Orochimaru not to see this - or ant other - particular Kekkei Genkai he might use. 'The proctors will see! Everyone will sense it!'

If we don't, that thing will kill you!

'We just need to avoid the tip!'

Then what do you suggest!? The aggravated Kyuubi demanded of his host, worry overlapping with anger. In answer, all Naruto did was put his hands together and form as thick an armor of wood around his torso and on his hands as he tried to push himself away from the sword. The sword still sliced right through the wood and into Naruto's skin, but Naruto was able to push away a bit from the tip before it could do more than just prick his skin and the first layer of muscle over his heart. There was a moment of triumph, but it lasted for only a second as the blade continued sliding through the wood and the flesh. Naruto and Kurama nearly really did manifest the fourth tail in their panic but suddenly, the sword retreated.

(He will later learn it is because of Anko's arrival to the scene: she had found out her old sensei was back and out for trouble and had come to fulfill her duty, but Orochimaru had reactivated her cursed seal and had made his escape before ANBU operatives could catch him.)

With nothing supporting him in the air anymore, Naruto started plummeting towards the earth and he knew, without a doubt, that he would die, either from the impact or from a stray branch or trap skewering him if he doesn't act fast.

So, throwing caution to he wind, eyes a bloody red from two different powers, Naruto put his hands together like he was going to pray and actually prayed he'll make it.
