If Naruto did not have the kyubi then my thoughts are that possibly Minato may not have died(not to say he wouldn't have had to seal it somewhere else) But say he didn't need to seal it. He would be under the teachings of his Father who is Hokage which leads me to think that he would not have turned out to be immature and become more considering. So then and there he would already become more of a stratigest. Not to mention he also has a large amount of chakara to begin with, without the kyubi. Then there is sage mode. So he would pretty much dominate.
And again, even if his parent's still died, more than likely he would have been told who his parents where and then he wouldn't be so troubled with loneliness because no one would have a reason to loath him.
Either way he would still dummy everyone just due to natural strength, intelligence and the fact he is to proud to give up.
Example: Have you not noticed his recent attitude change when he realized who his father was?
I realllly think so toI really think Naruto has a chance of becoming the Hokage now, in terms of skill. If granny Tsunade ever dies, look out world!
He just seems fit for the job. But one thing is, that it would seem to perfect if he became hokage. Like he mentioned, when him and Sasuke fight next; they will both die. Which concerns me because there goes the series... But I think that was a warning to explain that the end is near. Which I really hope it isn't
ANYWAYS I'm getting off topic. But back to Naruto being Hokage, if he did, I think after Tsunade passes away (which I hope she doesn't) It will be Kakashi, then later down the road when Naruto is old enough, he will be Hokage with Kakashi. But as I mentioned... It is either he becomes hokage and sounds cliche, or he and Sasuke dies and sounds cliche... I think Naruto is trolling us.
