I don't think it works like dat, the bijuus have different character, look @ the one tail, he is a funky one, the 8 tail is considerate, the 9 tail fool of pride. I won't say the 4 tail is weak.
i mean, the prophecy says that naruto will bring a great change to the ninja world. To fufil the prophecy, i think that he should not only be in konoha he should move around the world so as to bring the balance to the ninja realm. Do u get the message of this post?
