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.
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, 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.
Naruto's personality would be a blend of his own natural exuberance and the more composed natures of Minato and Kushina. He might be less impulsive as Minato's strategic thinking would influence him. Also, Kushina's strong - willed nature would make him more determined and less likely to be swayed by others' negative opinions.
Their relationship would likely become more of a partnership. With the power of the Rinnegan, they would be equals in a sense. Kushina would no longer just be Naruto's mother but also his comrade in arms. They would rely on each other's unique abilities that come with the Rinnegan, sharing knowledge and strategies.
If Kushina was alive in a fanfiction, Naruto's relationship with his father, Minato, would be different. They could all be a proper family, and Naruto would grow up with both his parents. His relationship with his friends might also change as he would have a more stable home life. For example, he might be more confident around Sakura and Sasuke, and his bond with them could be less about seeking acceptance due to his lack of family.
In terms of the overall ninja world, Kushina's survival could have a ripple effect. Her presence could have deterred some of the villains or influenced their actions differently. For example, Orochimaru might think twice about attacking Konoha if Kushina was there to defend it. And the Akatsuki might have to reevaluate their plans since Kushina's skills in sealing jutsu could pose a significant threat to their goals.
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.
If Naruto was the son of Kronos in fanfiction, it would completely upend the Naruto storyline. Kronos is from Greek mythology and has powers like time manipulation. Naruto might inherit such abilities, which would make his battles very different. He could potentially manipulate time to dodge attacks or age his opponents. His journey to become Hokage might be overshadowed by his newfound divine heritage and the powers that come with it.
