Im not saying he becomes Hokage at his current age, it wouldn't make sense. Akatsuki will be gone by the time Naruto is Hokage and the leaf village is under as much threat from Akatsuki with naruto just being there as it would be if he was hokage. Naruto has the greatest chakra capacity out of any other ninja except possibly kisame. Give him the years he needs for experience to improve his jutsu and taijutsu added with the kyubi chakra and you got yourself the next yondaime with a 9 nine tails demon fox inside him. Kakashi has said twice he thinks naruto will surpass the 4th also I noticed a few issues back in the manga Kakashi looking at Naruto training and and an image of the 4th above Naruto appears, is kakashi the first person ever to really notice an uncanny resemblance between the two?
