Well, if Naruto was trained by Kushina in fanfiction, it could make him a lot more in - touch with his Uzumaki heritage from the start. He might learn unique Uzumaki jutsus earlier, like some powerful sealing techniques. Also, Kushina's feisty personality could be passed on more directly, making Naruto even more determined and head - strong in a different way than in the original story.
In a fanfiction where Naruto is trained by Kushina, there would be several major changes. Firstly, Kushina's own fighting style, which was probably a blend of Uzumaki and Konoha - style ninjutsu, would be passed on to Naruto. This could give him an edge in combat that he didn't have in the original story. Secondly, Kushina being his mother, their bond would be extremely strong. She could have guided him through his emotional turmoil related to being an orphan and the jinchuriki of the Nine - Tails in a more motherly way. This might have made Naruto more stable emotionally at a younger age. Also, she could have introduced him to Uzumaki - specific training methods for chakra control and reserves, which could have made him a more formidable ninja much earlier in the story.
If Naruto were trained by Kushina in fanfiction, it would likely result in a different Naruto. Kushina was a strong - willed and skilled ninja. She could have taught Naruto things Minato didn't get the chance to. For example, she might have instilled in him a deeper understanding of the Uzumaki clan's history and traditions, which could have influenced his values and goals. This could lead to a Naruto who is more connected to his roots and perhaps more respected within the village earlier on because of his unique knowledge and skills.
Naruto would become more confident in his abilities. With Kushina's training, he would have a better understanding of his Uzumaki heritage and the power that comes with it. This new - found confidence would show in his battles and his interactions with others.
If Kushina were alive in Naruto fanfiction, it could change the story in many ways. For one, Naruto would grow up with a mother figure. He might not have faced so much loneliness and discrimination in the village as Kushina could have protected him. Also, Kushina was a powerful kunoichi. She could have trained Naruto herself, perhaps passing on unique Uzumaki techniques earlier. This could have made Naruto even stronger, more quickly.
In such a fanfiction scenario, the village of Konoha would be affected too. Minato is a respected figure. His abandonment could cause a scandal. Naruto might not have the same level of protection from the village elders. This could lead to different power dynamics within the village. Maybe other ninja clans would try to take advantage of Naruto's situation. Also, Kushina's family might react in various ways, some might try to find Minato and some might focus on taking care of Kushina and Naruto.
He could learn powerful sealing techniques. Kushina was known for her sealing skills, and she could pass them on to Naruto. This would give Naruto an advantage in battles and also in containing the Nine - Tails' power.
Well, one possibility is that Kushina might teach Naruto some unique Uzumaki clan techniques. For example, she could pass on her knowledge of sealing jutsus. Since she was a powerful kunoichi, she could train Naruto in combat skills that are specific to the Uzumaki style, which would give Naruto an edge in battles.
Well, in such a fanfiction, the Naruto world would be a chaotic mess. Naruto as Kushina's father would mean the timeline of events related to the Uzumaki clan and Konoha would be all jumbled up. His relationship with Sasuke would also be affected. They were rivals because of their different family situations and goals. But with this new family setup, Naruto's motives and Sasuke's perception of him would be very different. And Naruto's status in the village might be completely different too, as his relation to Kushina would give him a different kind of standing in the Uzumaki - related matters in Konoha.
This fanfiction could also change the relationships with other characters. For example, if Kushina hates Minato, the Third Hokage might have to step in more often to mediate between them. And the other villagers might also take sides, creating a divided village atmosphere that is quite different from the united one in the original story.
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.
Well, if Naruto got Kushina pregnant in a fanfiction, it would completely mess up the original timeline. Naruto was born to Kushina and Minato in the original story. If this were to happen out of the normal sequence, it could lead to all sorts of changes. For example, Naruto might not grow up as an orphan. He might have a very different upbringing with Kushina around. Also, the relationships he forms in the village could be different. His training with Jiraiya might not happen in the same way or at all, which would then impact how he develops as a ninja and his ability to face the various threats to the village.
In this fanfiction scenario, Naruto's training with Minato and Kushina would be intense. Minato, being a prodigy, would push Naruto to his limits in terms of combat skills and quick decision - making. Kushina would focus on Naruto's inner strength and the connection to his Uzumaki roots. This could result in Naruto having a more well - rounded set of skills from the start. He might not struggle as much with basic jutsu control and could potentially even master some advanced Uzumaki - specific techniques earlier. For example, he could have a better grasp on sealing techniques which are a big part of the Uzumaki clan's abilities. This would give him an edge in battles against opponents like Orochimaru or the Akatsuki members who often use or are affected by sealing jutsu.
