Prologue
9 years from Present Time
One Orochimaru can be seen looking over the genetic enhancement department of his lab as he is trying to perfect two formulas, one to evolve the body to newer levels of performance and the other to improve the body's processes in the hopes of better regeneration and healing.
"Test run number 19 of the Rebirth Formula for body enhancement and reinforcement." said Orochimaru in a tape recorder as he injects a mouse with said serum as the mouse begins to exhibit heightened aggression as a snake is put in the cage with the rodent.
The two fight and shockingly the Mouse wins as it rips the snake's head off. However before the mouse can do anything it suddenly falls over, mutating into an even more muscular mouse and dying.
"Test 19 failed on mice. It would seem that the subject developed Myostatin in the muscular structure." said Orochimaru as he goes towards a man tired down who is looking incredibly afraid as Orochimaru approaches with said formula as he proceeds to inject the man with the serum.
The man proceeds to gain similar attributes and tried to lunge at Orochimaru to beat him to death only for him to die similarly to the mouse he had used it on.
"Test 19 for humans failed." said Orochimaru as he goes towards a another side of the lab as he proceeds to pour out a vat of the Rebirth Formula as he goes to another part of his lab as he picks up another tape recorder. "Test 41 of the Pinnacle formula for cellular regeneration mouse phase ." said Orochimaru as he injects a mouse whose arm was cut off. It regrows but the mouse soon becomes disfigured savagely as Orochimaru says "Mouse phase onto Humans" as he goes over to a man that had both legs taken off by the knee.
The man screams out in pain as his legs grow back but he is subjected to being grotesquely deformed by the formula. Orochimaru sighs and says "Test 41 is a complete failure. If only I can perfect both these formulas I can gain the results for regeneration." as he thinks of what could be the cause of both formula failures as he goes to place the formulas with his previous versions in a vat would dissolve the two in arctic water.
As he is about to write down something a snake slivers up to his should and whispers into his ear. Orochimaru sighing thinks ' Well It seems that I am no longer a part of this village oh well might as well start my own.' as he abandons the laboratory after disposing of his failed formulas and leaving all data regarding them on the table. However they aren't truly failures as inside of the
Present Time
One 8 year old Naruto Uzumaki can be seen tied to a strange post beaten and bloody as his attackers laugh at his pain and misery as the leader says. "Well demon it's time to die and well be sending you off in a bang." As one of the lights a fuse to something. Naruto with his working eye sees where the fuse is going and discovers that he is tied to one of the rockets for the Kyuubi's day of defeat festival. Naruto struggles and invalid fails to break free as the rockets fuse soon lights the rocket and sends it flying into the air with the blonde haired Jinchuriki.
Naruto screams out in fright and fear as he is going high up into the air. As the rocket soon explodes, sending Naruto falling into the forest into an old complex that sees him land inside a vat of unknown chemicals that seem to be unaged or filthy. As inside of the seal on the exposed stomach of said Uzumaki things are going differently as the unknowing bacterium flows inside of his wounds .
Inside of the seal.
One Kyuubi No Kitsune is laughing its homicidal ass off as it sensed how its container had experienced hell.
'The kit's will is faltering and soon he will be nothing but a memory after he takes in more of my chakra.' thought the Kyuubi as his chakra is flowing into him as he begins to fall asleep from the rapid chakra flow unknown that Kyuubi's slumber will be his permanent until he reforms. As what the Kyuubi doesn't know is his chakra is what Orochimaru was missing in his vat of formulas that the young blonde had crashed into.
Outside of the seal and inside of Naruto's
As inside of the blonde Jinchuriki cellular structure, musculature, brain and overall physiology begins to get hidden abilities that he will have to tap into. As the Kyuubi's chakra seemingly stabilizes these failed chemical formulas and fusing them into his body as the blonde rapidly recovers from the injuries he has sustained from his fall. As the blonde wakes up from his injuries as he slowly gets out of the container. Walking home unaware that his body is experiencing something of superhuman proportions. As his sensor seems to have improved and his thinking process more open minded. While some of the bacterium goes dormant until a trigger needed for his true potential is unleashed..
In an Office of The Hokage
Hiruzen can be seen laughing at the report by a team of closely trusted Anbu for work in something vile and treacherous for him in particular. "Good, you are dismissed." said Hiruzen as he sets the report down.
'Good the brat's conditioning is going nicely. Soon he will be this villages loyal attack dog and protector.' thought Hiruzen as unknown to him their will be a reckoning like no other in the future.
Timeskip 4 years later
Naruto can be seen stealing the forbidden scroll of sealing from the Hokage Tower. As he goes towards the location his sensei Mizuki instructs him after failing the genin exam for the third time. As he stops and opens the scroll he discovers a scroll addressed to himself. He pockets it for later as he soon studies the shadow clone jutsu and the multi shadow clone jutsu.
(Everything Goes the Same as in Canon.)
Naruto at home opens the scroll addressed to himself. As he reads.
Naruto this is your mother Kushina Uzumaki. If you are reading this then I and your father Minato Namikaze the Fourth Hokage are dead from the Kyuubi attack. This scroll contains the greatest secret of the Uzumaki fighting arts and the sum total of the sealing arts of our clan that only you can access on the blood seal on the swirl on the seal. I only wish that you follow your own path and know where you come from. Your father sealed the Kyuubi in you for he didn't have a choice for no other baby was available. He was a good man who didn't want anyone to have the burden you now have. He hoped you would be viewed as a hero but I have a feeling that wouldn't be so due to those of the old guard of thinking in the village regarding power. Tread lightly my son, you will need to be around those in power that would seek to garner your power instead of your friendship and heart.
Signed Kushina Uzumaki.
Naruto for his part, having absorbed that he comes from a clan, his father was the Fourth Hokage, and his mother's warning thinks about his place in Konoha and questions the character of the Third Hokage after his meeting. Thinking back to his mannerisms around him how he talked about forgiveness to the people that have attacked him on several occasions, even how he didn't do anything about his sabotage in the Academy. Thinking on this makes Naruto question what his goal actually is, whether this was his to be exact.
Naruto is thinking hard as he proceeds to go to sleep as he thinks about what secrets he will be looking at in his clan.
