In certain fanfictions, Naruto's father could have left behind hidden jutsu or knowledge that Naruto discovers as he grows up. Regarding Sakura's parents, they may have had their own struggles within the village politics.

Another alternative is that Naruto is found by a mysterious hermit who lives in a hidden part of the village. The hermit teaches him ancient and powerful ninja techniques that have been forgotten by most. Naruto then uses these skills to make a name for himself and change the perception of those who once shunned him.

In a Sasuke and Sakura parents fanfiction, it could show how their parents' personalities influenced Sasuke and Sakura.
