Well, it would completely turn the story upside down. The family relationships are so crucial in Naruto. If Naruto were Kushina's grandfather, it would mean a whole new set of character dynamics. For example, Minato's relationship with Naruto would be extremely different. Instead of being his father, he would be some distant relative. And Naruto's connection to the Uzumaki clan would be much more complex and ancient. It could also change how Naruto obtains his powers. Maybe he would inherit some ancient Uzumaki abilities in a different way than in the original story.
In the fanfiction, a possible backstory could be that Naruto, after achieving great power and peace in his own time, decided to use his abilities to explore the past. During this exploration, he accidentally or purposefully got involved in the lives of his ancestors. He might have fallen in love with a woman from the Uzumaki clan in the past and had children. These children then passed on their genes through generations until Kushina was born. It could also be that there was some sort of experiment by an ancient shinobi that went wrong or right (depending on how you look at it). This experiment somehow connected Naruto's future self to be Kushina's grandfather by altering the fabric of time and family relations in a very strange way.
He could be a powerful and respected shinobi from the Uzumaki clan. Given the Uzumaki's reputation for strong chakra and unique abilities, Naruto's grandfather might have been a key figure in the clan's history.
In Naruto fanfiction, Kushina's pregnancy can be a significant plot point. It could explore the anticipation within the Uzumaki family and the village. For example, Minato might be extra protective, and the village might be looking forward to the birth of a potential powerful shinobi. Fanfic authors might also delve into how Kushina copes with the physical and emotional changes during pregnancy, adding depth to her character.
Another aspect could be that the fanfiction delves into how Kushina's presence affects Naruto's relationships with others. For instance, his relationship with Sasuke could be different. With a strong maternal figure in his life, Naruto might be more stable emotionally and be able to approach Sasuke in a more understanding way, which could potentially change the whole dynamic of their rivalry and friendship.
Yes, in many fanfictions, Hashirama is often depicted as Naruto's grandfather. Fanfiction writers like to create such family relationships to add new storylines and depth to the Naruto universe. It can lead to interesting plot developments, such as Naruto inheriting some of Hashirama's unique abilities or having a closer connection to the founding of the Hidden Leaf Village.
One idea could be that Naruto's grandfather was a great shinobi who had a unique jutsu that was lost over time. In the fanfiction, Naruto could discover some hidden scrolls that lead him to learn about this jutsu from his grandfather's past.
Yes, in certain fanfictions Jiraiya is indeed Naruto's grandfather. This alteration of the original Naruto storyline in fanfiction can create a whole new set of character dynamics. For example, it could mean that Jiraiya had a more direct role in Naruto's family history. It might also change how Naruto views his own family and his place in the ninja world. This kind of creative change in fanfiction can bring fresh perspectives to the well - known Naruto story.
Well, at first, it might be a bit awkward as they adjust to being husband and wife. But as time passes, they start to understand each other on a deeper level. Kushina could help Naruto deal with his insecurities and Naruto could support Kushina in her goals for the village. They might have small arguments here and there, but overall, their love and respect for each other would grow.
Kushina's training in the fanfiction might also impact Naruto's mental state. Knowing that his mother is there to train him gives him more confidence. He feels more connected to his family and his Uzumaki heritage. This new - found confidence reflects in his battles, where he is more fearless and decisive.
