Kakashi's relationships with the enemies he faced during the Kannabi Bridge mission would also be different. If he changes the outcome of the mission, some of those enemies might not become his enemies at all. For example, if he prevents certain events from happening, some ninja from the opposing side might end up becoming his allies. This would completely shift the power dynamics in the ninja world and his place within it.
If Kakashi time - travels to the Kannabi Bridge, his relationship with Obito would be very different. Instead of the tragic end they had in the original timeline, Kakashi might be able to save Obito. This would lead to a much closer bond between them, and they could become a powerful duo in the ninja world. They might also be able to change the future of the Uchiha clan together.
His relationship with Rin would also change. With Obito alive, the love triangle situation could develop in a completely new direction. Maybe Rin would develop feelings for both of them, or Kakashi would step back to let Obito have a chance with Rin. And his relationship with Minato - sensei would be different too. Minato would be impressed by Kakashi's knowledge from the future and might start training him in new ways.
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.
Another plot twist could be related to Kakashi's own abilities. Since he has knowledge of the future, he might try to use some jutsu or skills that he hasn't learned yet in his original time. But this could come with a cost, like draining his chakra too much or attracting unwanted attention from powerful enemies. He could also accidentally teach his past self some skills that change the course of his own development.
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.
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.
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 Naruto and Kakashi switch roles, Naruto's relationship with his students would be a major shift. He'd be the one imparting wisdom, and his students would look up to him in a different way. His friendly and open - natured self would make the learning environment more fun yet still challenging. Kakashi, on the other hand, would have to navigate Naruto's relationships with his friends. He'd have to deal with the tight - knit group that Naruto had. His more solitary nature might initially make it a bit difficult, but over time, he'd find his place within that group.
Naruto is often a common character. Since Naruto has a strong bond with Kakashi, he might be involved in Kakashi's time - traveling adventures. Sasuke could also be there. Their relationship with Kakashi in the original story makes it likely for them to show up. And of course, Guy would be a great addition. His friendly rivalry with Kakashi would add some humor and action to the time - travel scenarios.
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.
His relationship with Sasuke might improve. Since Kakashi would be his adoptive father, he could better mediate between Naruto and Sasuke. Also, with Kurenai around, Naruto might become closer to Hinata as Kurenai could encourage their friendship. And his relationship with the other Konoha 11 would be different too. He'd be part of a family that has strong ties in the village, so they might look at him in a new light.
