One possible plotline could be Minato teaching Naruto special jutsu early on. Since Minato was a very powerful ninja, he could pass on his knowledge of the Flying Thunder God Technique to Naruto at a young age, which would make Naruto even more formidable in battles against early foes.
A third plotline could be Minato guiding Naruto through the politics of the Hidden Leaf Village. As a former Hokage, Minato has a deep understanding of how the village works. He could teach Naruto how to navigate the complex relationships between different clans and factions, preparing him for his future role as a leader.
One possible plotline could be Kushina teaching Naruto some of her unique Uzumaki clan jutsus early on. This would give Naruto an edge in battles and also a deeper connection to his heritage.
One possible plotline could be Kakashi teaching Naruto some of his unique ninja techniques in more detail, like how to better use the Rasengan. Another could be Kakashi helping Naruto deal with his inner demons regarding being an orphan and the Nine - Tails. Maybe there's a plotline where Kakashi trains Naruto to be a more strategic fighter, not just relying on brute force.
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.
Perhaps the fox starts to develop human - like emotions and behaviors under Naruto's care. This could lead to some really heartwarming moments as Naruto helps the fox understand things like friendship and loyalty. They could then form an even stronger bond that surprises everyone in the village.
One possible plotline could be Obito teaching Naruto some unique jutsu that he learned during his time in Akatsuki. For example, he might show Naruto how to use certain space - time ninjutsu in a different way. Another could be Obito helping Naruto understand the Uchiha clan better, given his own Uchiha heritage.
One interesting plotline could be a time - travel scenario. The Naruto - like character goes back in time and gets to meet Minato. They then have the opportunity to learn directly from him, and perhaps even change some events in the past. This would add a whole new layer of complexity and excitement to the story.
One possible plotline could be Minato having to navigate the challenges Naruto faced as a child, like dealing with the villagers' hostility, but with his own knowledge and skills from his previous life. He might use his experience as Hokage to quickly gain respect and start making changes in the village at a younger age.
One interesting plotline could be Minato and Kushina returning during the Fourth Great Ninja War. They could turn the tide of the battle with their powerful skills. Minato's Flying Raijin would be a great asset, and Kushina's chakra chains could help in restraining powerful enemies. Another plot could be their return and how they interact with Naruto, teaching him new jutsus and sharing their experiences.
One possible plotline could be that Mikoto discovers Naruto at a young age and decides to take him in secretly. She then starts training Naruto in her own unique ways, perhaps combining Uchiha techniques with Naruto's natural abilities.
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.
