I thought that Naruto would be changed because of Kyubi being sealed in him, didnt they say it would change his chakra pathway or something?

Anyway isnt Naruto going to eventually merge with Kyubi completley, meaning that he will have the demon in his blood = passing on of the plood to his kids........at least thats the way I see it!

Advanced bloodlines wise I dont think they just evolved, MY theory is that they first advanced bloodlines began with the mixing of demon and human blood. I recon a random demon took a human shape got it on with a random girl or guy and hey presto CRAZY demon powers! Well thats the way I'm theorizing it, but hey I'm probs completley wrong
