What could be the plot if Naruto is trained by Pein in fanfiction?

His understanding of pain and suffering could deepen. Pein has a complex relationship with pain, and through his training, Naruto could gain a new perspective on it. This might make him more empathetic towards his enemies, or it could fuel his determination to end the cycle of hatred in a different way.

A possible plot for such a fanfiction would be that Naruto, being raised by Pein, is initially very loyal to the Akatsuki. But as he goes on missions and sees the real impact of their actions on innocent people, he begins to have doubts. He might then meet some of the Konoha ninjas secretly and start to understand their side of the story. This could lead to a big internal struggle within Naruto as he has to choose between the man who raised him and the village that his birth parents came from.

Well, one possible plot could be that Naruto starts to adopt Pain's view on justice. He might see the world as a place full of suffering that needs a radical change. He could begin to question the traditional ways of the Hidden Leaf Village and try to implement some of Pain's ideas in a more positive way, like finding a new system to ensure peace that doesn't rely solely on the power of the ninja villages.

One possible plot could be that Naruto is wrongly accused of something after the Pein attack. Maybe the village leaders believe false rumors that Naruto was in cahoots with Pein somehow. As a result, he is banished. He then goes on a journey to prove his innocence and in the process, he discovers new powers and allies. He might also encounter some of Pein's former followers who have their own motives and secrets related to what really happened during the attack.

One possible scenario in a fanfiction where Naruto becomes Pein could be that Naruto is exposed to some dark jutsu that alters his mind. This jutsu might be related to the Rinnegan's power. As a result, he starts to adopt Pein's ideology of bringing pain to the world in order to create peace. His friends would be shocked and try to bring him back to his normal self.

One possibility is that Naruto's new 'godlike' powers after the Pain arc are seen as a threat by the village elders. They fear he might become uncontrollable, so they banish him. This could lead to Naruto exploring new lands, meeting new allies or enemies, and potentially finding a way to prove his worth and return.

Well, in such a fanfiction, it might be that Naruto becomes extremely powerful like a god. Since he is trained by the Kyuubi, he could gain unique powers and abilities. Maybe he masters the Kyuubi's chakra in ways no one else has. He could use this power to defeat powerful enemies, protect his village in extraordinary ways, and perhaps change the entire shinobi world with his new - found god - like strength.

In this fanfiction, perhaps Hiruzen realizes Naruto's potential much earlier and decides to train him privately. He might take Naruto on secret missions to build his experience and confidence. This would not only strengthen Naruto's skills but also their bond, which could have a huge impact on the village's future.

Well, perhaps Naruto could learn some unique and powerful jutsu from Muu. Maybe Muu has a special training method that focuses on Naruto's chakra control and helps him unlock new levels of power. For example, Muu might teach Naruto how to better utilize nature chakra in a different way compared to what he learned from Jiraiya.

One possible plot could be that Itachi, seeing Naruto's potential and his importance for the future of the Hidden Leaf, decides to secretly train him. Itachi might teach Naruto advanced jutsu, especially those related to chakra control and unique Sharingan - inspired techniques. Naruto, under Itachi's tutelage, would grow not only in power but also in his understanding of the ninja world's complex politics and the Uchiha clan's history.
