Well, if Naruto was born with the Sharingan, it would completely disrupt the original power dynamics. He'd have an edge in combat from the start. For example, he could quickly copy jutsu like Sasuke does with his Sharingan. This might make his early training with Iruka and Kakashi very different as he'd already have a powerful dojutsu at his disposal.
If Naruto was born with Mokuton, the story would change significantly. For one, his relationship with the Hidden Leaf Village might be different. The Mokuton was a feared and powerful ability due to its connection with the First Hokage. Naruto could be seen as a greater threat initially. He might also have been trained differently. Instead of focusing on the Rasengan and Sage Mode, he could have been taught more nature - based jutsu related to Mokuton earlier on. This could have led to him being more powerful at a younger age and potentially changing the outcomes of many battles, like the fight against Orochimaru where he might have been able to defeat him more easily with Mokuton - based attacks.
Well, if Naruto was born in Iwa, the whole story would be flipped on its head. For one, he'd grow up with different values and training methods from Iwa. His relationships would be completely different. Instead of having friends like Sasuke and Sakura from Konoha, he'd have Iwa comrades. His ninja way might be more in line with Iwa's harsh and competitive environment. Maybe he'd be more aggressive in his fighting style. Also, the relationship between Iwa and Konoha would be more complex as Naruto could potentially be a bridge or a source of conflict between the two villages.
If Naruto were the son of Kakashi and Rin, his backstory would be completely rewritten. He would no longer be the orphan ostracized by the village for being the Nine - Tails' jinchuriki. Instead, he'd be part of a family with a strong ninja heritage. His development as a ninja would be shaped by Kakashi's teachings, which are more strategic and precise compared to what he learned in the original story. His social status in the village would be higher, and he might not have the same drive to prove himself. This could also change the way the Akatsuki views him. They might target him differently or even try to recruit him in a different way because of his family ties. The story would deviate from the original plot in many significant ways.
Well, if Naruto were Sarada's father in fanfiction, it would completely change the family dynamics. For one, Sasuke's role would be very different. Sarada's character might develop different values and abilities, influenced by Naruto instead of Sasuke. The relationship between the Uchiha and Uzumaki clans would also take on a new form, perhaps leading to new alliances and political situations within the Hidden Leaf Village.
If Naruto was born the same age as Itachi, the story would be drastically different. Naruto would be more mature and skilled earlier. He might have been involved in the Uchiha massacre situation. Maybe he could have even tried to prevent it, given his nature of not wanting to see people suffer. This would also change his relationship with Sasuke. Instead of being an older peer, he would be more of an equal in age, and their rivalry could take on a different dynamic, perhaps more of a mutual understanding from the start.
If Naruto was born a Saiyan, the entire Naruto storyline would be completely different. For starters, he'd likely have a tail and the ability to transform into a Great Ape. His power level at a young age would be much higher than in the original story. Instead of learning ninja techniques like the Rasengan, he might focus on mastering Saiyan ki blasts. His goal might not be to become Hokage but rather to become the strongest Saiyan in the universe, or at least on Earth. Also, his relationships with characters like Sasuke would change. Sasuke might see Naruto as an even greater rival, not just in ninja skills but also in raw power.
If Naruto was born as a girl in fanfiction, the initial dynamic with Iruka might be different. Iruka could be more protective. Also, Sasuke might view her in a different light, perhaps with a more complex mix of rivalry and underlying affection. And Naruto's relationship with Sakura could be more of a sisterly bond rather than a love triangle situation. It could also lead to different interactions with Jiraiya, who might train her differently or have different expectations.
Well, if Naruto was Ino's twin brother, it would completely change the dynamics in Konoha. For starters, Naruto might not have been as isolated as he was in the original story. Since Ino is from the Yamanaka clan, Naruto could have had early access to some of their clan techniques and knowledge. This could have made him a more formidable ninja from the get - go. Also, his relationship with Sasuke might have been different. Maybe he would have been more focused on his relationship with his sister and the Yamanaka clan rather than being so obsessed with Sasuke's approval.
Well, in a fanfiction where Naruto is born before the Third Shinobi War, it could mean that the prophecy about him might have been known earlier. This could have led to different training methods for him. Maybe the Sannin would have been more involved in his upbringing. Jiraiya could have started training him much earlier, and Tsunade might have been more focused on his physical well - being. Orochimaru, on the other hand, might have seen him as an earlier opportunity for power and tried to manipulate him much sooner. All these changes would have a huge impact on the overall Naruto storyline.
Well, in such a fanfiction, Naruto being a Kryptonian would mean he has heat vision. This new power could be used in battles against the Akatsuki. Instead of using Rasengan, he could simply use his heat vision to take out opponents. Also, his invulnerability would make him a force to be reckoned with. He could walk through most attacks without a scratch. His character might also change as he has to deal with these new powers and the responsibility that comes with them. It's an interesting concept that would mix the Naruto world with the Kryptonian lore.
