You could create a Root OC who has a unique relationship with Danzo. Maybe they are starting to question his extreme methods and are on a journey of self - discovery within the strict and secretive Root. This would add an interesting internal conflict as they have to balance their loyalty to Root and their growing moral compass.
The 'root naruto fanfic' often has a darker and more mysterious tone compared to the main Naruto story. This is because Root itself is a secretive organization. The fanfics may explore themes like loyalty, sacrifice, and the price of power within the context of Root. They can also introduce new jutsus or abilities specific to Root members, which adds to the uniqueness of these fanfics.
Create a special fighting style for your OC. Instead of using the typical ninja weapons and jutsu, they could use something completely different. For example, they might use musical instruments as weapons, and their jutsu could be related to sound waves. This would make them stand out not only in combat but also in the overall Naruto fanfic world.
It could be Naruto and Sai. Sai was from Root originally. They could form a deadly duo as Naruto has his powerful jutsu and determination, while Sai has his unique ink-based abilities and his own growth in understanding emotions and bonds, which could complement Naruto's personality well.
A major theme is redemption. Given that the Root Anbu are often involved in some rather shady deeds, a lot of fanfics focus on their journey towards redemption. Also, power struggles are common. There are always power dynamics within the Root Anbu and between them and other Naruto factions in these fanfics. It makes for some really interesting stories as characters vie for control and influence. And of course, friendship and camaraderie can also be a theme. Despite their tough exterior, some fanfics show the bonds that can form between the Root Anbu members.
One possibility could be that Naruto is kidnapped by Root agents and forced to undergo their harsh training regime. They might try to break his spirit and turn him into a tool for their shadowy operations, but Naruto's strong will and his belief in his friends could help him resist and eventually find a way to escape.
Well, in a 'oc brings root down naruto fanfic', it could be that the oc is a ninja with extraordinary abilities that Root has underestimated. The story might involve the oc uncovering some dark secrets of Root and using that knowledge to undermine and eventually bring them down. It could also explore the relationships the oc forms with other Naruto characters during this process, like Naruto himself or Sasuke, who might be either allies or foes depending on the plot.
