Naruto's fighting style would change significantly. Itachi's influence would likely lead to a more calculated approach. He would be more patient in battle, waiting for the right moment to strike. Kisame's brute force would add an element of power. Naruto might develop a new signature move that combines his chakra - control skills with water - style jutsu. His use of shadow clones could also be different. Instead of using them as a distraction or for mass attacks, he might use them to set up genjutsu traps, taking advantage of Itachi's expertise in that area.
If Naruto were raised by Itachi and Kisame, his fighting style would be a blend of their skills. Itachi's precise and strategic genjutsu usage would make Naruto more of a mental combatant. He could use genjutsu to create openings for his attacks. Kisame's proficiency in water - style jutsu and his raw strength would also play a part. Naruto might learn to manipulate water in ways he never did before, like creating large - scale water attacks similar to Kisame's. His overall fighting style would be less straightforward and more about outsmarting opponents through a combination of illusions and powerful water - based strikes, rather than his typical in - your - face combat style in the original story.
His fighting style would be more stealth - based. Itachi was a master of genjutsu and Kisame was strong in close - combat and water - style jutsu. Naruto might learn to use genjutsu more effectively, which is something he wasn't very good at in the original story. He could also incorporate water - style techniques into his attacks, making his combat more diverse. Instead of relying mainly on his shadow clones and Rasengan, he might use illusions to disorient opponents before going in for a kill with a water - enhanced physical attack.
His fighting style would be more diverse. With Tsunade's teachings, he might incorporate more precise and powerful physical strikes. And from Kushina, he could inherit some unique Uzumaki techniques. He would probably be more strategic and less reckless in combat.
Naruto's character development would be drastically different. Itachi's calm and strategic nature might temper Naruto's impulsiveness. He could learn to think before acting more often. Kisame's brute strength and loyalty could also shape Naruto. He might become more physically powerful in a different way than with Jiraiya's training. His view of friendship could change too. Instead of the large group of friends he had in the original story, he might be more reserved and have a closer, more exclusive bond with a few individuals, similar to the relationships within Akatsuki.
She could incorporate more stealth into her fighting. Zabuza is a master of assassination, so she would probably be trained in sneaking up on her opponents. This would be a contrast to Naruto's more upfront and brash fighting style. She might use the environment to her advantage more often, hiding in shadows or using mist (like Zabuza's Hidden Mist Technique) to surprise her enemies.
Her fighting style might be more refined. Kakashi is a very technical fighter, so he would likely instill in her a sense of precision. Unlike the male Naruto who often relied on brute force in the beginning, she might start with more calculated moves. For example, she could be better at using kunai and shuriken with deadly accuracy from the start.
His fighting style would likely incorporate more fire - based jutsu. Since the Uchiha are known for their fire - style techniques, Naruto would be trained in those from a young age. He might also use Sharingan - like abilities, even if it's not the real Sharingan. For example, he could develop a way to predict his opponents' moves more accurately, similar to how the Sharingan works.
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.
His fighting style would be more brute - force based. Instead of using all those ninja techniques in a strategic way, he'd just charge in and start slashing like Kenpachi.
Naruto's character would likely become more reserved in some ways. With Itachi's influence, he'd think more before acting. But he'd also become stronger and more confident. Kisame's tough training would make him physically tougher. Naruto might also start to question some of the things he learned in the village, as Itachi and Kisame have different perspectives.
His fighting style would probably incorporate a lot of puppetry. He'd use puppets in combat like Sasori does. Maybe he'd also use some of the unique poisons that Sasori is known for. His style would be less about brute force and more about strategy and misdirection.
Naruto's social skills would also be different. Instead of being the lonely outcast, he would be part of a family. He would interact with other ninja kids in a more positive way. His parents could also guide him in making friends. He might be more diplomatic in his relationships because he has seen how his father, as the Hokage, dealt with people. This would all contribute to a very different Naruto compared to the one we know from the original series.
