Well, in this kind of fanfiction, perhaps they time travel to the early days of the ninja academy. Kakashi could be a really cool teacher there, sharing his advanced ninja knowledge. Sakura might befriend some of the characters who later become important, like Naruto's parents. They could also learn a lot about the origin of the ninja world and the secrets that were lost over time. And when they come back to their time, they use this knowledge to make the ninja world a more peaceful place.
In a Sakura and Kakashi time travel fanfiction, they could end up in the past during a major war. Kakashi would be a great asset with his Sharingan and combat skills. Sakura, on the other hand, could help the wounded soldiers. Their presence in the past could change the outcome of the war. For example, they might be able to save some important characters who were supposed to die. This would then lead to a completely different future when they return to their own time.
In a Sakura and Kakashi time travel fanfiction scenario, they could be sent back to the time of the First Hokage. Here, they would encounter a much different ninja world. Sakura could learn about the original medical ninjutsu techniques from that era, while Kakashi could study the combat styles of the early ninjas. They could also play a role in some of the historical events, like the founding of Konoha. Their actions in the past would surely create a ripple effect that would change the future they came from.
One possible interesting plot could be Sakura time - traveling to a point where Kakashi is a young ninja still struggling with his past. She could use her modern - day knowledge and medical skills to help him in ways that change the course of his life. For example, she might be able to prevent some of the traumas he endured. Another plot could involve Sakura traveling to a future where Kakashi has become a Hokage, and she has to adapt to this new world while also dealing with her relationship with an older, more experienced Kakashi. A third plot could be Sakura getting stuck in a time loop that always brings her back to a crucial moment in Kakashi's life, and she has to figure out how to break the loop while also making sure Kakashi's future is secure.
One common theme is redemption. For example, Sakura might go back in time to correct mistakes or save Kakashi from a certain fate, thus redeeming herself or others. Another theme is the exploration of their relationship. Since time travel disrupts the normal flow, it allows for a deeper look into how they feel about each other.
Well, if Sakura and Kakashi time - travel, their relationship could become more equal. In the original story, Kakashi is Sakura's teacher, but in the time - travel scenario, Sakura, as an Anbu, has more skills and experience. They might start to see each other as true comrades, sharing equal responsibility in whatever situation they face during the time - travel.
Sakura's character often develops in significant ways in these fanfictions. When she time - travels, she is usually forced to rely on her own wits and skills more than ever. For example, if she travels to a time before she had her advanced medical training, she might have to relearn basic medical techniques while also using her future knowledge to make improvements. This can make her more self - reliant. Also, her relationship with Kakashi can cause her to become more empathetic. If she sees Kakashi in a vulnerable state, she may learn to understand his pain and grow as a more compassionate person.
There's also 'Time's Twist' which delves into the time - travel concept with Sakura and Kakashi. In this story, their relationship develops as they face the challenges brought about by the time - travel situation. The author does a wonderful job of exploring their characters in this new context. They have to deal with past events and how their knowledge of the future affects their actions and feelings towards each other.
One idea could be that Sakura, as an Anbu, travels back in time and tries to prevent certain tragedies in Kakashi's past. Maybe she stops Obito from 'dying' initially, which would change the entire Naruto storyline in a major way.
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.
I think Rin would be an interesting character to pair with Kakashi in time travel fanfictions. Since she was an important part of Kakashi's past, their relationship could be explored further. Maybe Kakashi travels back to save her from her tragic fate, and they end up having a different kind of relationship as a result.
I really like the fanfic 'Time - Twisted Bonds'. In this one, Kakashi and Naruto are sent back to a crucial point in the history of the ninja world. It has a lot of action scenes and also delves deep into the relationship between Kakashi and Naruto. It's exciting to see how they use their skills and knowledge to navigate the past.
