I awaken in naruto body as he was experiment with a seal jitus form his mother clan i take over his body.
Absorbing his memories i find i am twin brother to the "child of prophecy" and the one to get the kyuubi chakra as i absorb what naruto read in the clan lib.
I start to lulz uncontrollable and fall out my chair in the library lulz until i pasted out i appear in my new body mind scape.
I see the cage and the kyuubi massive eye open and he or she stare at me for a couple mins and then huff out your not naruto i smirk and turn my head side way and caught my appearance in the water.
Seeing i look like a demon with red eye and pale white skin and tail whipping behind me.
Guessing i dont keep my head down often and i get trapped in a seal and look to see Kushina and Minato in front they stare at me in horror on there face as my real look come undone my blood red horn out my forehead and my blood red tail unwraps around my waist.
They give me more fear full look and started calling me Kyuubi i couldn't help but start to laughter at them you think i am the kyuubi i gasp and laughter harder and as i stop i keep laugh small lulz at them no no you mental retarded ninja i sneered i am what you created neglecting naruto.
All his hate and raged at you neglecting him only giving Naruko attention and train for 11 year you even forgot poor naruto birthday not even a kiss or i love you i sneer and my eye darken and my energy level raise ki flood the area.
My own seal placed all over my body start to glow and KI and energy put out by my body become visible causing some to scream and run there to kill them self.
As i just by will and rage start to move toward Minato Kushina eye widening as i breaking the paralyzing seal on the ground.
Minato look sad and remorseful full raise his hand to a signal and i feel myself completely freeze up and pain come form the kyuubi seal.
The big seal on the ground start to shrink to me i keep myself form smrking as Minato come with in striking distance as he move to touch my forehead and the kyuubi i smirk and he have a second look of shocked on his face as my tail lash out cutting off his arm and travel across his chest cutting him to the bone.
I will not be quite i sneered out at minato i then notice my view shrinking and i black out and awaken in the kyuubi's seal.
Looking at the kyuubi what happen i asked he sneered and look out side the cage to see my memories to being wiped and out side changing to look happy and cheer i sneer in disgusted them most of plannted fake memories into my new mind body.
Going to walk out the gate Kyuubi speak up don't and reach a tail out and past by the gate bar and a different and more powerful shield pop up out side the bars burning his trail until he moved back.
Minato sneered the kyuubi spat his name put up a stronger seal on me thinking you were my fake i sneer at the though of Minato but smirked lightly at taking his arm and cutting him across the chest.
For 3 year later i and my body is 14 do me and kyuubi train and watch some of the prefect son Minato and kushina created.
Are there team sent out on a mission and Naruto is hit with something that destroy the seal placed over the original created/powered by the death god complete destroying it.
The fake naruto appear in the mind scape and freak out for a couple mins at the kyuubi appear he sneer what demon you cant touch me my father and mother add another seal on top of the original you cant do anything to me now.
The kyuubi smirked and looked past him not me but he can as fake naruto goes to turn he scream in pain as arm bust through his chest with his heart in it hand i i sneer and whisper into his ear but i can.
I bite down on his neck draining his knowledge of the last 3 year getting all train his parents did give him this time how close he got to his twin sister i will say form just some of the memories of Naruko "accidental" changing or naked here or there does it appear that Naruko have a crush and lusting on her twin brother the fake one not the original me.
Some the last thing i hear before pasting out or being full pulled into Kyuubi seal was Minato placing seal on my seal to control me if i some how broke out.
Over the 3 year me and kyuubi were able to "damage" the original seal so that will not work any more and some memorie of fake Naruto see that Naruko know those seal for safe reason.
I come to standing in a deep cave with the bad guy that fake naruto was fight smirking as he look at me i let my eye go blood red and in second i am in front of him with my hand through his chest then i bit him on his neck draining his chakra and knowledge.
One the seal on my side start flash and grow as i drain the guys chakra and pump it into the seal once he drain complete he look pale and withered into a mummy.
