Naruto's ninja style would likely be a blend of Sasuke's. He would be more stealthy and precise in his attacks. Since Sasuke is known for his Sharingan and lightning - based jutsus, Naruto might incorporate some of those elements into his own fighting style. He would also have a more calculated approach rather than his usual head - on, brash style in the original story.
Naruto's ninja style would be a unique combination. He would still have his signature Rasengan, but it might be modified under Sasuke's influence. Maybe he would learn to infuse it with lightning chakra like Sasuke's Chidori. His movement would be more fluid and less erratic. Sasuke would train him to be more strategic, so Naruto would be better at analyzing his opponents before making a move, rather than relying solely on his brute strength and willpower.
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.
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.
If Sasuke raised Naruto, Naruto would become very attuned to Sasuke's emotions. Sasuke is not one to show his feelings easily, but Naruto, growing up under him, would learn to read his every mood. Their relationship would also be influenced by the outside world. The other ninja clans might view this relationship with suspicion. However, Naruto and Sasuke would be united in facing any challenges, with Naruto learning from Sasuke's combat skills and Sasuke learning about compassion from Naruto.
It would be very different from the original Naruto story. Maybe Sasuke would grow up with Naruto's positive influence from the start, and there would be no need for their intense rivalry. Their relationship would be more of a father - son bond, and Naruto could teach Sasuke his ninja ways in a more nurturing way.
It could be really interesting. Maybe Naruto had some kind of secret past or mission that led to Sasuke's birth. It might show a different side of Naruto, one that is more fatherly and responsible, while Sasuke could struggle with this newfound knowledge and his feelings towards Naruto.
One possible story could be Sasuke in an alternate universe where the events of 'Road to Ninja' take a different turn for him. Maybe he teams up with Naruto earlier and they face the challenges together, with Sasuke having to confront his inner demons in a whole new way.
It would probably be full of intense training sessions. Naruto would grow up with Gai's energetic and positive attitude. He'd likely learn all of Gai's unique jutsu and fighting styles at a very young age, becoming an extremely physical fighter.
In a 'Naruto Raised in Kumo' fanfiction, Naruto would likely face different challenges. Kumo has its own political situation. He might be trained in Kumo's harsh training regimens. Also, his relationship with the Raikage could be a key factor in his development, as the Raikage's leadership style is quite different from the Hokage's.
In a 'Naruto raised by Kushina' fanfiction, it could be a heartwarming story. Kushina would likely be a very protective and loving mother. She'd teach Naruto about the Uzumaki clan heritage from a young age. Naruto might grow up more confident and less of an outcast as Kushina would be there to shield him from some of the village's harshness.
Well, in a 'Naruto Raised by God' fanfiction, Naruto might gain extraordinary powers. He could have a divine connection that makes him much stronger than in the original story. Maybe he'd be able to use god - like jutsus or have a special understanding of the world's secrets.
