One possible reason could be Naruto's independent nature. He has always strived to make his own path and not rely on his father's legacy too much. So in the fanfic, he might refuse Minato to show that he wants to be his own person, not just Minato's son.
Naruto's character development includes learning about sacrifice and the importance of bonds. In the fanfic, his refusal of Minato could be a sign that he has outgrown the need for a father figure in the traditional sense. He has formed deep bonds with others like Iruka, Kakashi, and his friends. These relationships have made him strong enough to face Minato and say no if he feels it's necessary for his own growth and the protection of those he cares about.
Well, it depends on the specific fanfic. Some fanfics might really emphasize Naruto's growth to be on par with Minato in terms of smarts. They could show Naruto learning from Minato's memories or having some sort of spiritual connection that transfers knowledge. However, other fanfics might focus more on other aspects of Naruto's character and not necessarily make him as smart as Minato.
Kushina could be an important character even though she's dead in the original story. In this fanfic, her spirit or memories could play a role in Naruto's upbringing. For example, Minato could tell Naruto stories about Kushina's feisty personality and her love for the village.
There's a fanfic called 'Minato's Return'. In this story, Minato somehow returns and gets to see Naruto's growth. It's really interesting to see how he interacts with Kushina, who is also there in the story, and how they both guide Naruto in new ways. The descriptions of their family bond are heartwarming.
Well, Naruto has had the advantage of learning from many great shinobi over time. He also has a unique bond with his friends which could potentially give him more strength. Minato, on the other hand, had a shorter lifespan to develop his powers. Naruto has had more time to grow and surpass his father in strength.
One interesting fanfic could be where female Naruto, with her father Minato alive, has to face new threats in the ninja world. In this story, she might train under Minato, learning his signature jutsu like the Rasengan in a whole new way. It could explore how having a father figure changes her path from the original Naruto's story.
Yes, there are many non - adult - themed Naruto Minato fanfics. You can find them on various fanfic platforms. For example, on Fanfiction.net, there are stories that focus on Minato's heroic deeds, his relationships in a platonic or family - like way, such as his role as Naruto's father and his contributions to the Hidden Leaf Village. These fanfics often explore his character development, his training, and his interactions with other important characters in the Naruto universe without any inappropriate content.
There are likely fanfics that depict Naruto and Minato having a deep emotional bond. It could be centered around Naruto learning more about his father's past and how that knowledge shapes their relationship. For example, they might go on a journey together to discover a long - lost family secret.
In this fanfic idea, when Minato summons Future Naruto, it could also be for emotional reasons. Minato missed out on seeing Naruto grow up. By summoning Future Naruto, he gets to see the strong and capable man his son has become. Future Naruto can then tell Minato about his life, his friends, and all the adventures he's had, filling Minato with pride.
