One possible plot twist could be that when they travel back in time, they accidentally change a crucial event that alters the future in unexpected ways. For example, if they prevent a key battle from happening, it might lead to a different power structure in the ninja world.
Well, perhaps the time travel is a result of some jutsu gone wrong. In the fanfic, Naruto could end up in a time when Yoshino was just starting to develop her skills. They could team up to face a threat that was present in that era but was long forgotten in Naruto's time. This would create an interesting dynamic as they combine Naruto's future knowledge and Yoshino's understanding of that time period.
One possible plot twist could be that Naruto and Tayuya travel back to a time when the Hidden Leaf Village was first founded. This would put them in the middle of the early power struggles and they might have to use their future knowledge to prevent a great disaster. For example, they could stop a rogue ninja from stealing important village secrets that could have changed the course of the village's history.
One possible plot twist could be that their time travel messes up the existing timeline in ways they didn't expect. For example, they might accidentally prevent important events from happening in the past that were crucial for the future they came from. Another could be that they find out they were meant to time travel all along to fix a long - hidden problem in the ninja world's history.
One possible plot twist could be that when they travel back in time, they accidentally change something that makes their future relationship even more complicated. For example, they might prevent an event that was crucial for their initial bond. Another could be that they end up in a time where their personalities are very different, like a more war - hardened Naruto in the past, and they have to re - learn to love each other. Or perhaps they travel to a future where their love has been forgotten, and they have to rekindle it while also dealing with the new world they find themselves in.
Well, one plot twist could be that fem Naruto, due to her different personality as a female, might form alliances in different ways during the time travel. For example, she could use her charm to get closer to some characters that male Naruto might not have. Shikamaru, on the other hand, might use his intelligence in new ways. Maybe he figures out how to change the future in a more subtle way that no one expects. Another twist could be that their relationship changes. In the original, they were friends, but during time travel, they could become something more, like romantic partners, which would completely change the dynamics of the story.
Maybe Naruto travels back to his own childhood days. He could use his knowledge as Hokage to help his younger self become stronger faster. He might also be able to prevent some of the hardships he faced, like not having enough food sometimes. This would not only change his own life but also the relationships he had with people like Iruka - sensei, who took him under his wing when he was a lonely kid.
One common plot twist could be that Naruto and Anko's time travel alters the future in unexpected ways. For example, they might accidentally prevent an important event from happening in the past that was crucial for the future they came from. Another could be that they find out they are related to some important historical figure in the past they travel to, which changes their perspective on their own identities. And sometimes, they may discover that the reason for their time travel was not what they initially thought, like being sent by an enemy to change the past for their own evil purposes.
Well, perhaps a really cool plot twist is that Naruto and Shizune time travel to a future version of the ninja world that is on the verge of destruction. They then have to figure out what went wrong in their own time to cause this and find a way to prevent it from happening. Or, they could travel back to a time when Orochimaru was still a good guy, but their presence somehow starts to corrupt him, leading to a whole new set of problems. Another idea is that they time travel and end up in the body of other characters, which is really strange and they have to adapt to these new identities while also trying to find a way back to their normal selves and their own time.
One interesting plot twist could be that when they travel back in time, they accidentally change a major event that alters the entire ninja world. For example, they might prevent the Uchiha massacre, which would have a huge impact on characters like Sasuke and Itachi. This could lead to a completely different power dynamic in the hidden villages.
One interesting plot twist could be that when they travel back in time, they accidentally change an event that was crucial for the formation of their friendship. So instead of being friends or at least allies later in life, they become enemies in the new timeline. Another could be that they go back to a time when their villages were at war, and they have to work together secretly to stop the war without revealing their time - traveling identities.
