Perhaps he'd use his knowledge from his own time to help female Naruto. For example, if there were any upcoming battles or challenges that he knew about from his past, he could share that information. He might also be a bit shocked by some of the cultural differences that come with being female in this new world. He could end up being a mentor figure to female Naruto, teaching her some of his ninja skills in a new way.
Well, one possibility is that Naruto might be really confused at first. He'd see this different version of himself as a female and might not immediately understand the situation. He could try to figure out how this time - travel happened and what it means for his world. Maybe he'd start to learn about the differences in how female Naruto is treated in this new world compared to his own experience as a male.
Well, in a fanfiction where Naruto travels to the past, he could meet his parents when they were young. He could also learn new jutsu from the past ninjas that were lost over time. Maybe he'd even be able to influence the early development of the Hidden Leaf Village in ways that would make it stronger in his own time.
One possibility is that Naruto enters an AU where chakra doesn't exist. Instead, there are other forms of power. He would have to learn how to use this new power from scratch. Also, the relationships between different ninja clans could be very different. Naruto might end up making new alliances and enemies based on this new dynamic. This could be a great opportunity for character development as he faces challenges that are completely different from what he's used to in his original world.
One possibility is that Naruto and Naruko are on a mission to save the multiverse in this fanfiction. They travel through dimensions to collect some special artifacts or powers that are scattered across different realities. Along the way, they might face challenges from the rulers of those dimensions who don't want them to take those things. This could involve epic battles and the forging of new alliances as they strive to complete their mission.
In this fanfiction scenario, Naruto could bring his ninja skills to the Def universe. He'd probably have to adapt to the new environment. For example, if the Def universe has different laws of physics, his usual jutsu might not work the same way. He might also learn new techniques from the Def universe and combine them with his own.
One possible outcome is that Naruto would completely mess up the timeline. His presence in the past might cause unexpected butterfly effects. But on the positive side, he could form an even stronger bond with his father Minato. He might also influence Kakashi in a new way, making him less of a lone wolf. And he could introduce some jutsu from his time to the past, which would be really cool.
He'd probably be super surprised. I mean, seeing yourself as the opposite sex is not something that happens every day. He might blurt out something like 'Who are you? You look like me!' and then start to realize the situation. He could be a bit embarrassed too, especially if female Naruto had some different mannerisms or ways of dressing.
Well, if Naruto travels to the future in fanfiction, he may encounter his descendants or versions of his friends that have changed a great deal. Maybe he would find that Konoha has evolved into a super - high - tech ninja village. He would need to learn about the new political situations, new enemies, and new ways of being a ninja. For example, he might have to deal with ninjas who can control artificial intelligence as their weapons. He would be confused at first but then use his determination and strong will to figure things out.
In such a fanfiction, Naruto might try to prevent some of the tragedies that occurred in the past. For example, he could stop the Uchiha massacre. He would use his knowledge from the future to change things. Maybe he'd also be able to save some characters who died early in the original story, like Jiraiya. And he could potentially have a huge impact on the relationships between different clans, as he'd know about future conflicts.
Another thing that could happen is that Naruto would change the relationships in the village. He could start to influence the older generation, like the Third Hokage, at a very young age. He might tell them about the future threats and get them to start preparing earlier, which would change the whole dynamic of the village.
He might try to change certain events. For example, he could prevent some of the tragedies that occurred in the original story. Maybe he would stop the Uchiha massacre by warning the clan or finding a way to resolve the conflict between the Uchiha and the village leadership.
