Minato could also teach Naruto about leadership. As the Fourth Hokage, he led Konoha. He could share his experiences on how to make tough decisions for the good of the village and its people. He might tell Naruto stories of past battles and how he strategized to win, which would help Naruto in his future as a leader in Konoha.
In some versions, Minato might start by showing Naruto a simple demonstration. He could create a small mark and then suddenly disappear and reappear near it, catching Naruto's attention. Then he'd explain that Hiraishin is about using these special marks to instantly transport oneself to a marked location.
Minato, being a prodigy himself, might teach Naruto to trust his instincts more. He could share his own experiences of relying on his gut feelings during battles. His teaching would focus not just on the physical skills but also on the mental aspect, which is crucial for a ninja. He would encourage Naruto to think outside the box and be creative in his ninja techniques, something that Minato was known for.
One challenge could be controlling the chakra flow for creating the marks accurately. Naruto has a large amount of chakra, but it's wild. So, he might find it difficult to precisely form the marks required for Hiraishin.
One popular theme is Minato getting to know Naruto in the afterlife. Since Minato died when Naruto was a baby, fanfictions often explore their relationship in a spiritual realm.
In fanfiction, Naruto and Minato often represent a connection between generations. Minato was a great ninja in his time, and Naruto is following in his footsteps. Fanfictions can explore how Naruto lives up to his father's reputation.
I'm not sure if there is such a specific fanfiction. Fanfiction can cover a wide variety of themes and scenarios, some of which might be rather strange or controversial. However, Naruto fanfiction often explores different relationships and alternate storylines, but this particular one seems a bit unorthodox and I haven't personally come across it.
One of the main similarities is their self - sacrifice. Minato sacrificed himself to save the village and his son. Naruto has also shown that he is willing to put himself in harm's way for the greater good. He's always the first to jump into a dangerous situation if it means protecting those he loves. Another aspect is their leadership qualities. Minato was a great leader as Hokage, and Naruto has developed into a great leader as well, inspiring those around him.
You can try websites like Fanfiction.net or Archive of Our Own (AO3). They have a vast collection of Naruto fanfictions. Just search for 'Minato' and 'Naruto' in the search bar, and you'll get a list of relevant stories.
Minato would likely be extremely shocked. Naruto is his son, and the idea of Naruto attacking him would be completely unexpected. He would probably try to talk to Naruto first, to find out what is wrong and why he is being attacked.
