I think I've finally found the willpower to wrench myself back into fanfiction! Rejoice!

...No one?

Okay.

This one has been loitering around in my head for a short while now. I'm putting a slightly new spin on the idea of an Avatar/Naruto crossover (Well not at first, but I have some pretty nifty plans for later on the fic) so I decided I might as well take a swing at it.

I apologise for the prologue being shoddy, I just really couldn't focus re-writing something that's happened in fanfictions a few thousand times. I know, such a cliche way of getting Naruto into another world, but it had to be done. I needed to keep it at a point in time where Naruto isn't overly powerful, but line it up with a big enough chakra blast that he could be popped into another world. My writing is sub-par for this chapter, but I doubt that will continue in future chapters, or at least I hope it won't. I also wanted pre-timeskip Naruto to be the one sent to the other world. Not that I have a problem with the whole post-timeskip Naruto ending up in other worlds, I've done it in my own fics, but I wanted Naruto to be rather weak, immature and young when sent into the Avatar world. His intended pairing wouldn't work if he was any older.

The next chapter should be up pretty soon, so I beg you to stick with me through the prologue. Heck, you can probably skip this prologue and it not affect the story you read at all.

Peace.

Disclaimer: If I owned Naruto or Avatar: The Last Airbender my bank account would be plump...unfortunately it's comparable a void.

Let the fic...Begin!

Prologue:

Our story starts in a valley, somewhere in the vast country known as Hi no Kuni.

The valley was a historical site, known to be the location where the two leading founders of the first great ninja village fought their last battle against each other. Hashirama Senju, and Madara Uchiha. They were two of the strongest men in their time, and many even believed if they were to be resurrected they would still be among the most powerful humans today.

It was in this valley that the two collided for the final time, with Madara controlling the Kyuubi- the nine tailed demon fox spirit that was rumoured to cause natural disasters with a flick of its tails- and Hashirama fighting back with the power of nature itself, his wood-release ability granting him control over nature's trees which he used to combat the corruptive power of the demon.

The valley had not come into existence until this battle occurred. The two men had changed the landscape with the power they possessed. The valley itself was a serene looking place, with a river running through it and two statues modelled after the great men, a sign of respect and remembrance to the heroes of a previous age. Or rather, that is what the valley had been a couple of hours previously.

Now it was a battlefield, it's serene nature disturbed by two new titans. Ironically, the two that had ruined this historical site were related to the men that battled here previously, and once again the valley was the location of a devastating fight between the two warriors.

The first of the warriors was the thirteen year old Sasuke Uchiha, a young ninja with black messy hair that clumped together into thick bangs. Due to him relying on a cursed seal for power - a seal created to give the user great power at a great price- his skin and hair had taken on an ashen gray tone and a star shaped black mark expanded from the centre of his face, along with the whites of his eyes having turned dark black. His irises were blood red, and three coma-like marks spread out from his pupils. Emerging from his back was a pair of hand-shaped wings. His horrific appearance was evidence of the corruption of the cursed seal.

Across the river was a boy of the same age with shocking wild blond hair. His eyes were typically bright blue, however they had taken on a crimson tone with animalistic slit-shaped pupils due to the power he had to use to match his old friend, the power of the nine tailed fox spirit that created the very valley they were fighting in. He was surrounded by a viscous, bubbling shroud of red energy that had fox like ears and a single tail. The boy himself looked almost like he had been raised by animals, with thick whisker markings on his face and claws as sharp as a katana. On top of this his neon orange jumpsuit was a mess, with a hole on the left side of the torso that exposed a steadily healing wound that had once gone clean through his chest. Additionally, his left arm hung limp at his side due to the corrosive nature of his power having damaged it beyond use. His name was Naruto Uzumaki.

It is here that we join one of the heroes of our story. We join him at this specific time because this is the day that Naruto Uzumaki vanished from the face of the Elemental Nations, never to be seen again.

The two teens stood on opposite sides of the river, the tension between them, coupled with their corrupt powers being enough to leave all silent except the waterfall, as no wildlife could stand to stay in the area.

Sasuke's face took on a bored expression as he observed his rival. "I'm not going back Naruto, I've made my choice. Nothing will stand in my way. Leave, before I'm forced to kill you." His statement only angered the animalistic Naruto further. His voice came out as a low growl, with a hint of remorse.

"Don't you get it, asshole? I'm taking you home, even if it kills me." The blond looked conflicted, but he began to form a chaotic orb of purple energy in his right hand, preparing to end the fight. Sasuke, true to his nature, looked unfazed by blond.

"You've become strong, I'll give you that. You can't match me, but who knows, if you leave now you might still become Hokage. Just give it up Naruto." there was a hint of fondness in his voice. Sasuke would never admit it, but he was proud of the growth of his teammate. Who'd have thought that the loser, the dead last of their class would be the only one able to stand equal with him in a landscape-destroying battle.

Naruto did not notice this at all, and his body tensed up. In preparation to fight back, black lightning formed in Sasuke's palm, screeching as it bit at the ground around him.

The fox-ninja slowly looked up and spoke in a near-whisper. "Give up...on telling me...to give up." A few tears rolled down his cheeks as he tensed up. It was at this moment that he realised it was completely possible that he would have to kill the one he considered a brother. He was a danger to the village, and despite Naruto not being the most academic ninja, he knew a threat had to be put down.

"Sasuke!" Naruto's voice came out as more of a roar than a shout as he pushed off from the rock with enough force to crack the cliff face. Sasuke merely screamed as he pushed off with just as much force, beating his wings to build up speed. Both teens flew at each other faster than most could track, their respective techniques held in front of them. Naruto's technique was an attack modelled on a blast from the spirit beasts, and Sasuke's was a specialised assassination technique.

"Chidori!" Sasuke thrust out his arm, a torrent of black lightning covering it.

"Rasengan!" Naruto's typical blue technique turned red as it mixed with the energy of the malevolent fox.

All was silent for but a split seconds, before the collision rocked the valley. One would think the heavens had been torn asunder. The two colliding attacks formed a black, purple and white sphere of swirling energy, the two teens struggling to overpower each other within. Black and blue lightning arced up into the sky, whilst swirling purple and red energy tore trenches in the ground.

Inside the dome of energy Naruto realised his attack wouldn't hold out much longer. The Kyuubi's chakra had done too much damage to his body, and whilst it healed him at the same time it was beginning to take its toll. This was it. Both attacks had lost a fair amount of energy clashing against each other, but coupled with the damage to his body, Naruto could not continue and his Rasengan gave out. With wide eyes he watched as Sasuke plunged what was left of his Chidori into his chest. It didn't bite as deep as the first time, but it still pierced right into his right lung. He coughed out a small amount of blood in the instant they began to fall.

The orb they were suspended within began to shudder. Lightning arced, tearing vicious paths between the land and the sky. Water began to rise into the air, defying gravity as the wind howled and tore at the valley. And then, in the blink of an eye, it was gone. The sphere, the water that had been levitating around it, the lightning, all gone.

God, that prologue was a pain to write. Sub-standard to my normal stuff but I couldn't stand re-writing even a small portion of the valley of the end fight.
