GreatestSin wrote: as far as i remember he gaved him his remaining chakra, it was right before he tried to attack madara and use hashis jutsu, but he was killed, than, kabuto healed him with medical ninjutsu and hashi dna so that his body could regenerate faster, this would also explain why naruto isnt ghetting the rinngan, sasuke gained it with hashis dna (asura chakra), and since naruto didnt gain indra chakra he cant awaken it...

btw, madara had indra chakra despite the fact that sasuke was the new host, he used the rinnegan and had the super-life force + healing which he gained from hashi dna (asura chakra) ^_^ CORRECT!! Both Naruto & Sasuke received six paths chakra(Indra/Asura chakra). Sasuke awakened rinnegan cause he has the sage's eyes. Naruto never got rinnegan cause he only possessed the sage's body. Naruto lacks the things needed to awaken a dojustsu.

Asking why naruto didnt awaken the sage's eyes is same as saying why sasuke didn't awaken the sage's body.
