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.
Minato might show his protectiveness by always being near Naruto in spirit. For example, he could leave behind some kind of jutsu or power that activates when Naruto is in great danger, like a hidden seal that releases a powerful defense.
At first, Naruto and Kushina might start to distance themselves from Minato. They could avoid him and not talk to him as much. As time goes on, the hatred might grow deeper. Naruto could start to oppose Minato in public or in important village matters. Kushina might also try to influence others in the village against Minato.
Minato being alive in fanfiction could mean more guidance and protection for Naruto. It could also lead to new alliances and conflicts within the ninja villages.
Another good one is 'Hidden Feelings'. In this fanfic, the author slowly builds up the relationship between Minato and Naruto. It starts with small interactions and gradually develops into something deeper, with great character development along the way.
Another way is through training. Naruto might be trained by someone who knew Minato well, like Jiraiya. They could teach Naruto the same strategies and ways of thinking that Minato used. Also, Naruto could study Minato's past battles and learn from his techniques and decision - making processes. This would gradually make him as smart as Minato in terms of battle intelligence and leadership skills.
There might be a fanfiction where Naruto discovers some hidden secrets about Minato through a special jutsu. For example, he could find out about Minato's unfulfilled dreams and then strive to achieve them in his father's name. It would add an emotional depth to their relationship within the story.
There are also authors who focus on creating unique scenarios for Naruto and Minato. They might come up with ideas like Minato teaching Naruto some super - rare jutsu that was lost over time. These kinds of creative authors are great in the Naruto and Minato fanfiction world.
Well, if Naruto fought Minato in a fanfiction, Naruto could win. He has the Nine - Tails' chakra and has trained with some of the greatest shinobi. But Minato is no slouch. He was a prodigy in his time. However, Naruto might have a chance if he combines his Sage Mode with the Nine - Tails' power. This could overpower Minato's speed - based techniques. It's all speculation though, as it's a fanfiction scenario.
