They would likely have to rely on each other more. In a normal Naruto story, they are separated by time and death. But in this fanfic, they are brought together in this unique situation. Minato would have to learn to see Naruto in a new light, not just as his son but also as someone who is going through a very difficult and strange experience. Naruto would also see Minato as more than just the hero he always idolized. Their relationship would grow deeper as they face this challenge together, sharing their fears, hopes, and frustrations along the way.
Through shared experiences. For instance, they could participate in a special event in the game world that forces them to trust and depend on each other. This would be a great start to developing their relationship.
At first, Naruto might be in awe of his parents, especially Minato who is a legend. But as time goes on, they would become more like a normal family. They would have arguments over small things like any family does. However, their love for each other would always prevail. Kushina would be the emotional anchor of the family, while Minato would be the strategic thinker. Naruto would grow up with a strong sense of family values, and they would all be there for each other through thick and thin, which is very different from Naruto's lonely upbringing in the original story.
Well, for Sasuke, Minato's reanimation could change things. Sasuke might see Minato as a symbol of the village's past that he once despised. But seeing Minato's relationship with Naruto could make him rethink his views. As for Kakashi, he would be overjoyed to see his sensei again. This could strengthen the bond between Kakashi and Naruto as they both have a connection to Minato. And for Hinata, she would be happy for Naruto to have his father back, which could also bring her closer to Minato in a way, as they both care about Naruto.
In a fanfiction, an overprotective Minato would be like a storm cloud over Sasuke and Naruto's relationship. Minato's actions, driven by his concern for Naruto, would constantly disrupt the natural development of Sasuke and Naruto's friendship. Sasuke would see Minato as an obstacle to his connection with Naruto. Naruto, while loving Minato, would also feel caged by his overprotectiveness. This could lead to a downward spiral in their relationship if not resolved. But if they all sit down and talk things through, it could transform into a more positive and understanding dynamic.
The relationship can be developed by having Minato appear in Naruto's memories more vividly. For example, Naruto could start having flashbacks of Minato's training sessions or family moments that he didn't know about before. This would make Naruto feel closer to his father.
Another way is to create a common enemy that forces them to quickly adapt to each other's power systems. If a villain has the ability to nullify either ki or chakra, Goku and Naruto would have to find a way to use the other's power system. So Naruto might start using ki - based attacks while Goku tries out some basic ninjutsu moves. This would make for an interesting exploration of their different power systems in the fanfic.
Bash may approach the pregnancy with a strategic mindset. He would plan for the future, like ensuring they have a proper home and enough resources. Kenna would be more focused on the present, dealing with the physical and emotional changes. She might be more in tune with the baby's movements and development. They would need to communicate a lot during this time, as there would be so many decisions to make, from medical choices to lifestyle changes for the sake of the baby.
The emotional bond would be stronger. Naruto wouldn't have to face the pain of growing up without a father. Minato could be there to cheer him on during his training and be a source of comfort when Naruto faced difficulties, like when he was bullied as a child. He could also help Naruto better control the Nine - Tails' power from the start.
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.
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.
