Another aspect could be the duality of power. In the Naruto series, power is often seen as a means to protect or gain status. However, in 'naruto duality fanfiction', power could be shown as both a curse and a blessing.

It might create a more morally gray area compared to the relatively clear - cut good vs. evil in the original story.
