The hero will be an important, beloved and influential person in the shinobi world at the same time he has an important, untold past. The hero will be strong, but he will not be that strong, excessive strength that came without explanation, just under the guise that he is the hero of the story. The hero will go through moments of weakness and strength and will face everything with strength and weakness as well. If you were to say why is he a hero, from my point of view as an author I do not consider the hero a hero if he does not have moments of weakness and strength and has great strength because of a dark past in which he was weak at one time for example : Naruto, Itachi, Kakashi, Sasuke, and many others in the story.
