So i got this interesting idea when i was reading a Naruto fanfiction one..
(Before i start, this shouldn't be an evil Naruto who just kills everyone that looks at him wrong, i want a naruto that is cold and intelligent and uses any advantage he can get to survive)
What if Naruto was smarter then everyone believed but hid it because of the hate.
What if Naruto figured out that he he was the Jincchuriki of the nine tailed demon fox.
After he failed his exam, Mizuki approached him and told him about the 'second test'
What if Naruto stole the scroll and ran away from the village...
What if Naruto was branded a missing-nin and went into hidding.
What if Kurama contacted Naruto after he ran away and told him the whole truth.
(You could also make Kurama like Naruto or they made a deal where Naruto will release him before his death so they can work together)
He learned all the jutsus, seals and techniques in the seal and became a shinobi to be feared...
After he finds about the truth about his parents death he honors his parents sacrifice and decides to protect konoha
