In this fanfic, Naruto may develop unique abilities related to the Uzumaki clan. Kushina's influence would mean he has a deeper understanding of their power. For example, he might be able to use the Uzumaki's natural resilience in a more offensive way. Also, his connection with the Nine - Tailed Fox could be more harmonious as Kushina had experience with the tailed beasts. She could help Naruto form a better bond with the fox, leading to new and more powerful forms.
Naruto could have a greater control over his chakra. Since Kushina would be there to guide him, he would likely avoid some of the pitfalls he faced in the original story. His physical strength might also be enhanced as Kushina could train him in ways that utilize his Uzumaki bloodline more effectively.
He'd probably be more confident. Kushina's love and support would make him feel secure. He wouldn't have that same loneliness - driven need for attention like in the original story.
Naruto would likely be more confident. Growing up with his parents, he wouldn't face the same neglect and ostracism. So he wouldn't have to constantly seek attention in a loud or brash way.
His physical abilities would be enhanced. Constantly running, climbing, and fighting in the forest would make him stronger and more agile. His stealth skills would be top - notch as he'd have to hide from the forest's predators.
His relationship with Iruka would be different. In the original, Iruka was like a father figure to Naruto. But if Naruto was raised by Minato and Kushina, Iruka would be more of a regular teacher. With Sasuke, they might not have that initial rivalry based on loneliness. Instead, they could be friends from the start. And Naruto's relationship with the village elders would also change. Since he was raised by the Fourth Hokage, they might treat him with more respect and have different expectations of him.
His chakra control would probably be better. In a temple, he might learn meditation techniques that help him master his chakra more effectively. Also, his physical abilities could be more refined in terms of balance and grace, like a monk's movements.
Naruto's combat style would be more refined. Sakumo was a highly skilled ninja, and he would teach Naruto better swordsmanship skills perhaps. Naruto's taijutsu could also be more precise and calculated. Also, Naruto might develop better chakra control earlier, as Sakumo could instill in him the importance of efficient chakra usage from a young age.
His personality would likely be more stoic. Kisame is a rather reserved and tough character, and growing up with him would probably make Naruto less exuberant. He might not be as quick to trust others as he is in the original story.
Naruto's training would likely be more intense and survival - based. Zabuza was a tough and unforgiving trainer in his own right. He might push Naruto to his physical and mental limits from a young age, making Naruto more resilient in combat. For instance, instead of the relatively structured training in the Hidden Leaf, Naruto could be thrown into real - life combat situations early on to learn quickly.
His sense of humor would be different. Anko has a dry and sometimes dark sense of humor. So Naruto might crack jokes that are a bit more on the sarcastic side and less goofy. For instance, instead of his usual over - the - top pranks, he might play more calculated and sneaky pranks inspired by Anko. Also, he would be more confident in his own abilities from an earlier age, as Anko would encourage him to trust his instincts.
In such a fanfic, Naruto might grow up with a much stronger sense of family. Kushina could pass on her Uzumaki tenacity and unique skills directly to Naruto. He might be more confident and less of an outcast as Kushina would surely protect him from the villagers' scorn.
