Naruto isn't powerful/the child of prophecy because the manga is named "Naruto"....the manga is named "Naruto" because he is the character that kishimoto wanted to be the powerful child of prophecy. I wasn't surprised in the least bit when I first saw Naruto defeat top class shinobi like the akatsuki, or completely control kuramas power. People shouldn't complain/get butt hurt when Naruto succeeds in any way. Narutos fate has been sealed from the beginning to be one of the greatest ninja ever.
