This is a question I have been thinking about for a long time. I cant understand why Naruto chakra mode is different from the other tailed beasts. Is it because his Yin-powers was sealed away by the 4 hokage, and that he just have Yang-powers? but when he was in his fight against orochimaru, Naruto transformed into the normal bijuu mode.
Here you can read about narutos nine tal chakra mode: http://naruto.wikia.com/wiki/Yang_Release
I would appreciate if you write your opinion.
