The Nine Tailed Fox is a beast to be feared. With one blast he can destroy a lot of stuff! Of course Naruto’s far faster and at this point….far Stronger! With one blast Naruto can destroy whole mountains. Naruto can also make shadow clones which would definitely overpower The Nine Tailed Fox. The Nine Tailed Fox has always been inside Naruto, but that will be his downfall. He just didn’t have the skills to take Naruto down, but that’s because he’s helped Naruto improve so much. Without him Naruto may not be as tough as he is now. Naruto wins.
