naruto with 5 elements

I don't know if he'll really be able to. I believe it was mentioned by Kakashi that a person can only have two chakra elements at most, so having all the elements as one's chakra's nature would be unlikely. But it's Naruto we're talking about anyway, he who had mastered the sage mode at such a young age and even protected he's village and friends so many times and did the amazing things to prove himself and help others, I guess that time will come. But I still think it would be too Gary Stu if he did. ^^

Well, he is a stubborn and determined fellow just like his teacher, so I think if he has the will, he will be able to master them all.

Hello. In the manga, he started as a naughty boy. But little by little he changes and becoming more dependable (in his own way). Now (in the manga series), he already mastered the form of the beast with the guidance from Uncle Bee (the eight-tailed jinchuuriki). Although his beast form isn't like Uncle Bee but the form resembles more like The Sage of Six Path. Hence, I conclude here that he (Naruto) might be able to master all the elements just like the Six Path sage (man, if he mastered all 5 elements, he'll be like the Avatar).

If he'll try to master those other elements, i'm sure he'll be able to. I know Naruto have lots of potential in the series and he can really achieve something if he'll try to attain it. Believe it.. :)
