His taijutsu might be more refined. Rin, having trained with Kakashi and Obito, could pass on some unique close - combat techniques. Naruto might also have a better understanding of chakra control from an earlier age. Since Rin was good at medical ninjutsu, Naruto could potentially combine that with his own chakra - based attacks in creative ways.
Naruto's ninja skills would see a major transformation. With the Uchiha Clan's influence, he'd have a greater understanding of the Sharingan's capabilities and how to counter it. His training would focus on using his chakra in a more efficient and deadly way. Instead of his mass - produced shadow clones, he might learn to create clones with more specialized functions, similar to how the Uchiha use their Sharingan - enhanced clones. His physical combat skills would be enhanced with the Uchiha's taijutsu training, which emphasizes speed and accuracy. Also, his ability to sense chakra would be sharpened as the Uchiha Clan has a strong sense of chakra awareness within their own clan members.
His view of the ninja world could be more idealistic. Rin had a certain purity about her. Naruto might strive for a world that is even more harmonious than in the original story. He could also be more focused on the well - being of his comrades, as Rin always put others first. For instance, he would be quicker to offer medical help or emotional support to his friends in difficult times.
His ninja skills would be different in several ways. Firstly, his chakra control would be more advanced as Kurama could guide him from an early age. He'd probably have a more natural affinity for using the Nine - Tails' chakra in combat. His stealth skills might be lacking since Kurama isn't exactly known for being stealthy. And his taijutsu would likely be more brute - force based, taking advantage of his enhanced strength from Kurama.
His ninja skills would be more focused on stealth. Vampires are known for their ability to move quietly and undetected. So Naruto would likely incorporate that into his fighting style. He might also have enhanced speed, which would make his attacks faster and more unpredictable.
Sakura's medical ninjutsu skills would likely be more refined. Since Rin was an experienced medical ninja, she could teach Sakura advanced techniques early on. Sakura might also be more proficient in stealth and perception skills as Rin could have passed on her own knowledge in those areas.
Naruto's character would likely be more complex. He'd be less naive perhaps. Growing up with Obito and Rin, he'd have a different understanding of the ninja world. He might be more secretive too, as Obito has his own secrets.
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.
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.
