A/N: As far as I am concerned, I own nothing but the numerous plot bunnies roaming about in the pastures of my brain..
Kyuubi, a centuries old menace of pure Chakra and malice, undefeated by just about everything ever in the history of the shinobi nations. Everyone knows how he was created, when the Sage of Six paths broke the 10 tail into 9 smaller, more managable demons, the Kyuubi no Yoko being the strongest of the 9 so it held the majority of the 10 tails power..
However not many know the 10 tails was known by another name oh so long ago, in a different shift of time It was known as the Black Beast and after it devoured all of it's original shift..past, present, future, everything it shifted itself into this plane where it ran afoul of The Sage of Six paths and was split.
However I am getting off topic it appears..This is naught but a small amount of back story that led to the events of the life of Naruto Uzumaki.
The sounds of battle could be heard all around, along with the cocophany of roars and the sounds of the earth itself shaking with each movement the giant kitsune took...Minato sighed looking out over the battle from atop his summon, Gamabunta. He kneeled, patting the giant toad on his head. "You ready for one last fight old friend?"
The toad boss hummed slightly while chomping on it's pipe slightly. "As ready as I'll ever be. Ar you sure Minato? You know Kushina would kill you if she were alive to see this?.." He spoke sadly to his long time friend, the Yondaime of Konoha.
The blonde haired man nodded, his face like stone as he steeled himself for what he was about to do. Gamabunta rushed forward, hopping at a speed not many saw the old toad produce, his blade drawn as he clashed with the Kyuubi no Yoko, blocking a tail or two with his blade, as his summoner worked on his head, doing one handed seals while drawing in blood on the newborns stomach, his eyes glowing an eerie cerulean blue, even the sclera having change color. He almost lost his concentration when a tail caught the toad off guard, tearing a long gash through his eye and down his face, the wound bleeding freely but soon it was quiet, time almost seaming to have stopped for Minato and Kyuubi, the seal on his son's stomach glowing bright white. "SHIKI FUIN!"
The last thing Kyuubi felt in it's physical form was..peace..peace from the constant hate it had felt all of it's rage gone as it was absorbed into it's new jailor. Shinigami floated above the three blade in it's mouth as the transfer worked, He looked at Minato, a Hero to many but also a Demon in the eyes of an entire country..Willing to sacrifice everything, including his own son to save this village he loved with all his heart and soul.
The Shinigami took pity and floated closer to the Kyuubi's essence, draining into the newborn, he saw the powers that the boy would have and quickly inscribed a seal into his arms and back, connected with the shiki Fuin on his stomach, implanting the memories the boy would need into the Kyuubi.
Happy with his work he finished the process, taking Minato's soul into himself, before gently lowering the boy onto the ground, seeing the old man, the Sandaime rushing to the scene, before disappearing, leaving Naruto to his fate.
"You're gonna pay fro what you did to this village demon, You're gonna pay slow.." The sadistic nin almost cackled as his helpers, civilians, held the boy down and he extracted the long, shart kodachi from his back, letting the boy see the gleam of the metal blade in the light from the festival behind him.
The seven year old boy took a deep breath to scream just s the fireworks began, illuminating the night sky and drowning out his sobs and cries for help..The blade was lowered slowly, razor sharp edge pressing to the boys right arm, at about mid bicep, slicing as it touched skin, easily going through the thin fabric of his shirt.
He felt the blade sinking into his arm, screaming in pain as blood gushed from the wound, pooling on the alley floor, having sliced an artery. Soon the blade touched bone and the nin forced downwards, hearing a snap and crackle as the bone broke and the arm was cut off completely leaving the boy a bleeding stump behind, he sobbed uncontrollably, blubbering and making noises of pain and agony. He had never felt anything so painful in his life.
The nin above him stabbed the blade into the ground and pulled out a kunai. "Stop fucking staring at me like that you damn Demon!" and he proceeded to cut the boys left eye clean of the socket, taking the boys, beautiful cerulean blue and stomping on it.
There was almost an audible snap as all sound from the boy ceased, he was surrounded by black and red energy, it didn't feel like chakra and it didn't feel like the kyuubi either, the energy congregated on his lost limb and he found himself rising, the men that had been olding him down, bacing away in terror.
"You'll Pay.." His voice was raspy, full of pain, his now gone left eye socket began glowing red and the black energy that took on the form of an arm grew deep red claws, and he grabbed the nearest civilian, growling as he absorbed the very life force from him, healing the other mnor wounds they had inflicted first.
He dropped the dead civ like a sack of potatos and in a second was on the nin that had taken his arm, the fire works still hiding the screams that came from the alleyway, this time though they were notthe screams of a terrified and tortured boy..they were screams of terror as each and every adult in the alley was torn limb from limb, their injuries healing him whenever he inflicted them upon them.
Every time he drained energy his hair gained more and more silver until they were all dead and the power dissipated, leaving the boy coated in blood, it in his hand, on his clothes, and all over his hands..He looked at his right arm, and instead of flesh he found nothing but black metal and leather belts wrapping around it, his seal was still intact on the arm bt faded from black on his skin, to white on his new arm, he prodded it and felt the touch that he would have from his old arm, and almost sobbed in relief as he found his left eye there once again.
If any one looked at him they wouldn't see the Naruto they had become accustomed to, they would see sunkissed blonde hair streaked with snowy silver, his left eye having turned red instead of cerulean blue. It wasn't more than a few seconds later when he ran out of the alleyway, trying his best to avoid the crowds on his way back to his apartment, he didn't wnt a repeat of this..from now on people would have to earn his trust or he would be forever wary of them..
But now..Now Naruto had power, he wouldn't let anyone hurt him or anyone close to him again..Now he just had to train.
A/N: Hope you guys like the chapter, I went through three different versions of how Naruto gained the first of his new powers, but this one just came out the best, lots of gorey detail too and if you didn't enjoy it i'm sorry :3
