Naruto is influenced by a powerful, antagonistic entity named the “Nine-Tails” because some powerful wizard-like ninja named “The Fourth Hokage” had sealed its power into Naruto when he was newly-born during the attack. This legend precedes the timeline of the series. Just like Harry, when Naruto was old enough, scars of the Nine-Tails attack drove everyone away from him because they see the evil in him.

Wanting to be accepted, the entire series circles around Naruto’s adventure towards being the greatest Hokage of the village, facing off against many other ninja clans and entities to defend his village and the world while trying to control the monstrous power from within him.
