One possible plot could be Naruto struggling to control the power within Danzo's arm. Maybe the arm has some unique jutsu or abilities that Naruto has to learn to master. He might face challenges from those who fear the power of the arm or want it for themselves.
In this fanfiction, Naruto could initially be repulsed by having Danzo's arm. But as he discovers the secrets it holds, like hidden techniques or a connection to an ancient power, he starts to see it as an opportunity. He could use it to protect his friends and the village in ways he couldn't before. However, he also has to deal with the negative reputation associated with Danzo while having his arm.
One possibility is that Naruto, as Danzo's apprentice, would be exposed to a different side of the shinobi world. He could be trained in more stealthy and dangerous jutsus. However, his nature would likely conflict with Danzo's ruthlessness, leading to internal struggles within Naruto as he tries to figure out where he stands.
Another aspect could be that the successor discovers some long - hidden secrets left by Danzo. These secrets could be related to powerful jutsu or ancient ninja lore. And as they uncover these secrets, they have to decide whether to use them for the good of the village or keep them buried to avoid causing chaos.
Well, one possible plot could be Naruto growing up under Danzo's influence. He might be trained in more underhanded and secretive shinobi techniques. For example, he could be taught to prioritize the village's security above all else, even if it means using morally gray methods. This would put him at odds with some of his friends who follow more traditional ninja values.
Well, one possibility could be that Naruto grows up with Danzo's strict and secretive ways. He might be trained in more underhanded ninja techniques. But at the same time, he could inherit Danzo's sense of loyalty to the village, though in a more extreme form. Maybe he'd struggle to balance the dark side of Danzo's teachings with his own desire for friendship and acceptance, which was a big part of his character in the original series.
One possible plot could be that Danzo, seeing Naruto's potential, decides to take him under his wing secretly. He could train Naruto in more underhanded and strategic ways compared to the normal ninja training. Naruto might initially resist but then start to see the value in learning different perspectives of being a ninja.
One possible plot could be that Danzo, despite his controversial nature in the original Naruto series, sees potential in Naruto. He might train Naruto in the ways of stealth and intelligence gathering. This could lead to Naruto having a more diverse skill set, different from what he learned from Jiraiya. Maybe Danzo would teach Naruto some of the Root's unique jutsu, which Naruto could then adapt to his own style, making him an even more formidable ninja.
Well, perhaps Danzo kidnaps Naruto because he sees Naruto as a threat to his secretive and often unethical operations. He might fear that Naruto will eventually expose his wrongdoings. So, he takes Naruto to a hidden location and tries to keep him there, but Naruto's friends like Sasuke and Sakura would then start a rescue mission.
The plot could involve Danzo falling in love with a female jonin. He might initially hide his feelings as he is a very private person. But as they are assigned on a mission together, they start to bond. He could be attracted to her combat skills and her strong will.
One possible plot could be that Naruto, with his godlike powers, is able to see the good intentions behind Danzo's actions that were previously misconstrued. He then works with Danzo to bring about a new era of peace in the ninja world. Danzo, with Naruto's influence, starts to use his resources and influence for the greater good instead of his own political gain.
One possible plot twist could be that Naruto has to struggle with the dark legacy of Danzo while still trying to uphold his own ideals of peace and friendship. He might face distrust from the village at first because of his relation to Danzo.
