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.
One possible reason could be a miscommunication in the fanfiction. Maybe some secrets were kept from Naruto about his parents that made him feel betrayed when he found out, thus leading to hatred.
In some fanfics, Naruto might be made to hate Minato and Kushina due to a sense of abandonment. If the story is written in a way that emphasizes how Naruto grew up alone and suffering, he could project his anger onto his parents for not being there for him. For example, he might think that if they were alive, he wouldn't have had to endure the taunts and loneliness in the village.
It might be due to jealousy. If Minato was getting more attention or praise in the village for his achievements while Kushina felt overlooked, that could create resentment. Say, Minato was constantly being hailed as a hero for his speed and battle tactics, and Kushina, who also had great power, felt like she was in his shadow.
The fanfiction could develop this hatred through the introduction of new characters. These characters might feed Naruto false information about Minato and Kushina, making him question their motives and ultimately hate them. For example, a character who has a grudge against the Uzumaki family could manipulate Naruto.
Fanfiction can explore their relationship by delving into their unfulfilled time together. For example, showing how Minato and Kushina would have raised Naruto. It could also explore their shared experiences, like how they all have a connection to the Nine - Tails. Maybe in fanfiction, they have family adventures where Naruto learns from his parents' skills and wisdom.
Many fanfictions show their relationship as one of mutual respect and admiration. Minato is often portrayed as being attracted to Kushina's strong will and red - hot hair, which is a symbol of her fiery personality. They start as friends, training together and gradually realizing their feelings for each other.
On a more personal level, they could face internal guilt. As Naruto grows up and achieves great things on his own despite their neglect, Minato and Kushina may realize what they've missed out on. This realization could cause them a great deal of internal turmoil and regret for not being there for their son when he needed them.
Naruto's character development in such a fanfiction would likely be very different from the original. He may become more withdrawn at first, hiding his pain of being ignored. But as time goes on, he could develop a stronger sense of self - reliance. Since he doesn't have his parents' support, he has to figure things out on his own. This might make him a more independent and resourceful ninja in the long run.
In many Naruto fanfictions where Naruto meets Kushina and Minato, it often creates a very emotional scenario. Naruto finally gets to meet his parents who he has only heard about. It could be a heart - warming reunion where they share stories, hugs, and Minato and Kushina get to see how far Naruto has come.
In many Naruto fanfictions, Minato is often portrayed as an even more brilliant strategist and a loving husband. He might be shown using his Hiraishin no Jutsu in creative ways to protect Kushina. For example, in some stories, he uses it to surprise her with little gifts or to show up just in time when she's in danger.
