PRODIGY? lol what would he do without Kurama?
Well, without Kurama... How many people were shown to master Senjutsu??? Hashirama - the god of shinobi, Jiraiya - legendary Sanin, Kabuto - Had to freaking experiment on his own body cos normally it wouldn't be able to handle Senjutsu...
Like I said before in some threads, Naruto learned summoning jutsu on a large scale at the age thirteen, he mastered sage mode at age seventeen, created new jutsu Rasenshuriken, in sage mode he's a sensor as well, Kuchiyose no jutsu gives him access to one of the most dangerous genjutsu technique. People say he has little jutsu which is not true, different variations of rasengan are different jutsu, just like for example, Chidori and chidori Nagashi...
And he's learned by now how to use his Kagebunshin really effective... and there's more... Anyway only dumb person would recognize Naruto being gifted especially in chakra manipulation techs...
Without Kurama he's still a prodigy in a way
