Naruto is a staple of modern anime. It features an incredible world, reliably entertaining side characters, and one of the most beloved shnen protagonists of all time. Naruto went from a lonely, mischievous little kid, to the hero of his village, and eventually, he became the Hokage that he always wanted to be. He did so through a myriad of power-ups and new forms, but surprisingly, there was only one form that he actually earned himself: the original Sage Mode.
