Have you notice the Change in the fox Power? When the Fox had it, it was red color poisonous to the touch, Evil. Outside the Fox and in Naruto its white color, warm and life giving. Like a blanket with two sides. Or is the the user? Chakra it self is neither good or evil its just energy its colored by the User The Fox is a Demon, it hates and that hate makes the chakra red color, evil cold and deadly to the touch. Naruto is child like Good Nature always striving to find the good and do the good so the chakra takes on a pure nature giving life and warm to the touch. What do you think is it the user of the chakra that makes the chakra change in power and look?
That sounds right man, and i believe its the user now, or a bloodline specialty, i mean it only makes sense that he's a distant relative of the senju so naruto might have opened up a new level of jinchuuriki when he poured the kyuubi's chakra into the section it remains, Because, Perhaps their really is a so6p correlation thats still a mystery. On the other note, that possibly its the user, maybe it was just love to make naruto the way he was, cuz we know KB uses the cloaks with tails, and naruto just gets a super saiyan power up, a little mystery, none we cant solve.
This leaves me on another not, to where if it is the user, or a bloodline, what if sasuke got a tailed beast and he got the same cloak as naruto gained, but his revolved around his eyes only to make the conspiracy true that naruto is the body, and sasuke is the eyes.
