Some people believe that it is Kyuubi Ninetails that gives 火影忍者 some power. And without him, he would most likely die. Than again he is the main character with will power to never give up regardless the challenges put before him. 火影忍者 Uzumaki always seems to overcome challenges regardless the odds. As a matter of fact Ninetails does play a big role in Naruto's strength. And powers.
