The fanfic could be interesting because it might introduce new plot twists and turns. For instance, the oc's methods of bringing down Danzo could be completely unexpected. It could also show the consequences of Danzo's downfall on the village and the other characters, which could lead to a whole new set of storylines and character developments.
Well, it could be through having some unique jutsu or abilities. Maybe the oc has a special power that can counter Danzo's Sharingan-based techniques or his political influence within the Hidden Leaf. For example, if the oc has a power to expose all of Danzo's secrets at once, it would undermine his authority and bring him down.
One possible motive could be revenge. Maybe the oc or someone close to the oc has been wronged by Danzo in the past. So, to seek justice, the oc decides to take him down.
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.
In this fanfic, the oc could bring Danzo down by winning the loyalty of those who were previously under Danzo's command. If the oc is able to show these people that Danzo's ways are wrong and offers a better alternative, they might turn against him. This would weaken Danzo's power base and eventually lead to his downfall. Additionally, the oc might be able to use Danzo's own paranoia against him. By creating situations that make Danzo act rashly, the oc can expose his true nature to the rest of the village.
Obviously, there would be the original character (oc) who is the central figure in bringing Root down. There might also be some well - known Naruto characters like Kakashi or Tsunade who could be involved in some way, either helping or hindering the oc's mission.
A great fanfiction is 'Danzo's True Legacy in Root'. It portrays Danzo in a more sympathetic light. It tells the story of how Root was originally founded to protect the village from threats that the regular shinobi forces couldn't handle. And Naruto, through his own journey of understanding the darker side of the village, comes to realize that there was some good in what Danzo was trying to do, and he helps to reshape Root into a more positive force.
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 plot is crucial. A good fanfiction might have a plot that involves uncovering the secrets of Root. It could show how Danzo's actions, although controversial, were part of a bigger plan for the village's survival. For instance, in a fic, Naruto could be on a mission to discover the truth about Root and in the process, he has to face his own prejudices. This kind of plot keeps the readers engaged as they are eager to know what the real deal with Root and Danzo is.
The setting also plays a big role in such a fanfic. If the story is set in a time when Root is under more scrutiny from the village leaders, it might be easier for the OC to escape. For instance, if there are political tensions and Root is trying to keep a low profile, the OC could take advantage of the chaos. Also, the OC's knowledge of the Root's hideouts and routines would be essential for a successful escape. They might have memorized the patrol schedules or known the secret passages within the Root's base.
