The main characters are obviously Naruto and Minato. Naruto is the protagonist of the Naruto series, a young ninja with the Nine - Tails sealed inside him. Minato is Naruto's father, a very powerful ninja known as the Fourth Hokage. In this time - travel fanfiction, their interactions form the core of the story.
Well, in this type of fanfiction, a cool plotline might be Naruto and Minato having heart - to - heart conversations about Naruto's mother. Minato could share stories about Kushina that Naruto has never heard before. Also, they could work together to change some past events that had a negative impact on the future. Maybe they prevent a certain tragedy from occurring in the past, which then changes the present in a positive way. For instance, they might stop the death of an important shinobi who was crucial for the stability of the Hidden Leaf Village.
In a Naruto time - travel Minato fanfiction, Minato could be sent to the future. There, he would see how the village has changed, and might be shocked to find out about the Akatsuki and their actions. He could then work with Naruto and the others to fight against the Akatsuki using his unique skills and knowledge of the past. For example, he could teach Naruto some new jutsu that was lost over time.
If Minato time - travels, it could change a lot. For instance, if he prevents the Nine - Tails attack, Naruto would grow up in a very different environment. He might not be the underdog he was in the original story. Also, if Minato changes things during the Uchiha clan's situation, Sasuke's story would be completely different. Konoha's political situation would also be altered. There would be less animosity between different clans perhaps.
In many Naruto fanfictions where Naruto meets Kushina and Minato, it often creates a very emotional scenario. Naruto finally gets to meet his parents who he has only heard about. It could be a heart - warming reunion where they share stories, hugs, and Minato and Kushina get to see how far Naruto has come.
It would be very close. Naruto has always longed to know his father, so when he travels back in time to meet Minato, they would quickly bond. They'd probably start training together right away.
Well, it could be that Naruto finally gets to experience a real family moment. Since Minato is his father, Minato could introduce Naruto to his mother, Kushina. This family reunion in the past could be filled with emotions. Naruto might learn about his family's past, like how his parents met and fell in love, which is an important part of family history.
One great 'Minato x Naruto Time Travel Fanfiction' is 'A Father's Chance'. In this fic, Minato travels back in time to Naruto's childhood and gets to be the father he always wanted to be. It's really heartwarming to see their interactions.
Jiraiya is likely to be a popular character. He was Minato's teacher and has a strong influence on Naruto as well. In a time travel fanfiction, he could provide a lot of wisdom and help in the different situations they encounter. Also, Tsunade could be important. Her leadership skills and medical ninjutsu could be very useful when they are in the past, and she has her own history with both Minato and Naruto's family.
One possibility is that Naruto's presence in the past would disrupt the timeline significantly. However, it could also lead to a strengthening of Konoha. He and Minato could work together to improve Konoha's defenses and train the next generation of ninjas earlier. This could potentially change the entire future of the ninja world, making it a more peaceful place with Naruto's knowledge from the future.
