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.
One possible plotline could be Kakashi using his knowledge from the future to prevent Sakumo's suicide. He might try to change the events that led to Sakumo being shamed in the village. For example, he could expose the real reasons behind certain missions' failures that were wrongly blamed on Sakumo. This would not only save Sakumo but also potentially change the entire future of the Hidden Leaf village, as Kakashi's own life and development were deeply affected by Sakumo's death.
One interesting story could be about baby Kakashi's first training session with Sakumo. In this fanfiction, Sakumo might be teaching baby Kakashi basic ninja skills like how to hold a kunai properly. It could show the cute and clumsy attempts of baby Kakashi as he tries to mimic his father.
Their bond can be shown through silent communication. Since Kakashi is a baby, he can't talk much, but Sakumo can understand his needs and wants just by looking at his expressions. For example, if Kakashi is reaching for a certain object, Sakumo immediately knows what he desires. Another way is through shared dreams. In the fanfiction, it could be written that they have a special connection where they sometimes share the same dreams, which could be about their future ninja adventures or just happy family moments.
A possible plot is that Sakumo discovers Kakashi has an extraordinary talent very early on. So he tries to find the best way to nurture it without pushing the baby too hard. For example, he might give Kakashi a small kunai to play with and notice that he has an unusual grip and focus on it. Then, he could start introducing very basic ninja concepts related to the kunai, like balance and aim. Or perhaps there is a story where Sakumo has to leave baby Kakashi with a friend for a short time and when he comes back, Kakashi has learned something new and unexpected from that person.
Sure. There's a fanfiction where Sakumo instills in baby Kakashi the importance of loyalty to the village and family. He tells Kakashi stories of their ancestors and how they always protected Konoha. This story emphasizes how family values are passed down through generations in the Hatake family.
One great Sakumo Hatake time travel fanfiction is 'Back in Time with Sakumo'. It shows Sakumo going back to his early days and using his future knowledge to change things. It has an interesting plot and well - developed characters.
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.
Since Naruto has more knowledge of the future, Kakashi might start to rely on him more, which could shift their relationship. Naruto could also see a different side of Kakashi from the past, and this new understanding could deepen their connection. For example, they might have to face some challenges together that make them trust each other more than before.
Another great Kakashi back in time fanfiction idea is him going back to the time right before Obito's 'death'. He could then change the events that led to Obito's fall to the dark side. This would rewrite the entire future for the Ninja world, as Obito played such a crucial role in many of the later events, including the Fourth Ninja War.
