Their relationships would likely become stronger. They would have to rely on each other more in the unfamiliar past environment. For example, Naruto might look up to Kakashi even more as he sees how much Kakashi has grown and changed. Sasuke might be more open to the idea of teamwork as they face challenges together in the past.
Well, initially there could be some confusion. The past versions of themselves might not understand the future versions. But as time goes on, they would start to work together better. Sakura could learn from her future self how to be a more confident and powerful kunoichi. And Kakashi would have a chance to mentor his team in a whole new way, which would deepen their bond.
The time - travel experience would bring them closer in a unique way. They would share memories and experiences that no one else in their world has. This would create a special kind of camaraderie. Naruto and Sasuke might have a different dynamic as they see how their actions in the past can affect the future. And Kakashi would be like a guiding light for them, but also learn from their fresh perspectives, further enriching their relationship.
Their friendships could become stronger. Facing the unknown future together would likely bring them closer. They would rely on each other more than ever.
If Team 7 went back in time, Naruto and Sasuke's relationship could become stronger earlier. Maybe Naruto could understand Sasuke's pain from the past better and be able to prevent some of the rifts that formed between them. Sakura might also be more confident around Sasuke in the past, knowing what she knows now. Their bond as a team could be tighter as they work together to change things in the past without making big mistakes.
With Minato, Kakashi's relationship could also shift. If Sakumo is alive, Kakashi may not be as eager to prove himself in the same way. Minato might see a different side of Kakashi, one that is more at peace with himself. This could lead to a more mentor - mentee relationship based on mutual respect and understanding rather than Kakashi's need for validation.
If Kakashi travels back in time, his relationship with his father would be completely different. Instead of the strained relationship due to his father's perceived failure, he could support his father and build a strong bond. With his students, if he travels to the future and then back, he might have a new perspective on how to train them. He could be more lenient or more strict depending on what he saw in the future of their development.
Kakashi's abilities would likely be enhanced in the past. He has all the knowledge and skills he's gained in the future. So, his combat skills would be more refined. His Sharingan would be even more powerful as he would know better how to use it. He might also be able to teach his younger self some new jutsu that he learned over the years.
Their relationships would become much stronger. Kakashi would no longer have to bear the guilt of Obito's 'death' and Rin's loss. Obito would be extremely grateful to Kakashi for saving his life and would likely view him as an even greater friend and ally. Rin would also be happy to have both of them by her side, and they could form a very tight - knit team.
If Kakashi goes back in time, his relationship with Rin would be complex. He might try to protect her more, which could lead to a different dynamic between them. He would be more aware of the threats she faces and could be more proactive in her safety. With Guy, he could be a better friend from the start. He could join Guy in his challenges and competitions more often, strengthening their rivalry - friendship. And when it comes to the Third Hokage, Kakashi could offer more insights based on his future knowledge. This might make the Third Hokage rely on him more, and Kakashi could become a more important figure in the village at an earlier stage.
When Boruto goes back in time, say to the era of the Third Hokage. His relationship with the village elders and the teachers at the ninja academy would be completely new. He would be seen as an oddity since he has knowledge and skills that are not from that time. He might form unexpected friendships with some of the young ninjas of that era. His relationship with his own family members in the past, like his grandparents, would also be very interesting. He could learn a lot about his family's history and values from them, which would change how he views his family in his own time.
Well, one possibility is that they could use their future knowledge to prevent some of the tragedies that occurred in the original timeline. For example, they might be able to save some characters who died. They could also change the relationships between different ninja clans, making the ninja world more harmonious. And perhaps they would train harder in the past to become even more powerful ninjas in the future.
Well, for Naruto and Sasuke, their relationship might become even stronger earlier. In the past, they could train together more and understand each other's pain from the start. Sakura might be more assertive in her relationship with Sasuke, as she has the knowledge of what will happen in the future. She could try to prevent Sasuke from going down a dark path right from the beginning. And among the other members of Konoha 12, they might form closer bonds as they rely on each other more in this strange new situation of being in the past.
