Well, in this fanfiction, Naruto could be sent back in time due to some kind of time - space ninjutsu gone wrong. Once in Uzushiogakure, he realizes that the village is on the brink of destruction. He decides to use his experience and his Uzumaki heritage to his advantage. He may find a way to boost the natural defenses of the village, such as strengthening the seals around it. He could also try to influence the training methods of the shinobi in Uzushiogakure, teaching them new techniques or improving the old ones. And of course, he would be in the middle of all the political drama and rivalries, trying to keep the peace and ensure the survival of the village.
Naruto's character would likely become more in - touch with his Uzumaki roots. In his own time, Uzushiogakure was already destroyed, so going back and seeing it in its glory would give him a deeper connection to his heritage. He might also become more patient and strategic. Instead of his usual head - on approach, he has to be more careful in the past as any wrong move could change the future drastically. For example, he can't just go around using his most powerful jutsu without considering the consequences on the timeline.
Well, it could be that Naruto discovers some ancient evil is threatening Uzushiogakure. So he uses his signature jutsu like Rasengan and Shadow Clone Jutsu to fight off the villains. Maybe he teams up with some of his friends or discovers some new power within himself along the way.
There could be some of the older Uzushiogakure ninjas who survived the previous disasters. They would play an important role in guiding Naruto about the secrets of the village. And maybe some new characters could be introduced, like a young Uzushiogakure ninja who looks up to Naruto and helps him in his quest to save the village.
In some fanfictions, Naruto might use his strong influence and the power of his bonds. He could convince the other villages to help, pooling resources like building materials and ninja manpower. With his own Uzumaki heritage and knowledge of Uzushiogakure's past, he'd guide the reconstruction process.
One possible scenario in this fanfiction could be that female Naruto, with her knowledge of future events, is able to prevent Minato's death. Maybe she uses her skills and the element of surprise to change the course of the battle where Minato was supposed to sacrifice himself. She could also have some unique abilities or jutsu that she uses to outwit the enemies and keep Minato alive.
In some fanfictions, Naruto might save Obito during time travel by using his strong will and the power of friendship. Naruto could convince Obito to change his ways before he goes too far into the dark side. He might show Obito the future of the village and how his actions are causing more harm than good.
One popular plot could be Naruto using his knowledge of future events to prevent Rin's death. For example, he might stop her from being in the wrong place at the wrong time. Another plot could involve Naruto teaming up with past versions of his friends to protect Rin. He could use his advanced jutsu skills that he has learned in his own time to fend off the threats.
He might encounter unique and dangerous beasts in Uzushiogakure. Fanfiction often has new and exciting creatures for the protagonist to face, and Uzushiogakure's different environment could be home to such beasts.
One possible scenario in such a fanfiction could be that Harry uses a time - turning device to go back in time. He might first have to figure out exactly when the Marauders are in danger. Once he gets there, he could use his knowledge of magic from his own time to save them. For example, he might know a more advanced defensive spell that wasn't known during the Marauders' era.
