Well, in a Naruto born a Saiyan fanfiction, the power scaling would be crazy. Naruto would probably have Saiyan instincts. He'd be more aggressive in battles, like how Saiyans are. His chakra system could be intertwined with Saiyan ki. Maybe he'd have a different way of sensing enemies, more like a Saiyan's battle sense. And his growth would be exponential. Instead of waiting for years to gain new powers like in the original Naruto, he could gain power-ups just from intense battles, like Saiyans do when they recover from near - death experiences.
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.
Well, if Naruto were a Super Saiyan in a fanfiction, the power dynamics would be completely different. Naruto's already strong ninja abilities would be amped up to a whole new level. His Rasengan could potentially have the destructive force of a Super Saiyan's ki blast. And his speed would be incredible, making him even more of a force to be reckoned with in battles against foes like Sasuke or the Akatsuki. Maybe he'd be able to fly too, which would change the way he approaches combat situations in the Naruto universe.
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.
If Naruto was born as a fox demon, the entire plot of Naruto would be drastically different. For starters, his appearance would be more fox - like from the very beginning. He might not be as ostracized in the village as he was originally. Since foxes are often seen as symbols of cunning and intelligence in Japanese folklore, people might be more in awe or fearful of him. His relationship with Sasuke could also be altered. Instead of a rivalry based on human emotions like envy and the pursuit of power, it could be more of a power struggle between two different demon - like entities. Also, his training with Jiraiya would have to be adjusted to his fox - demon nature, perhaps focusing more on his inborn abilities rather than learning new jutsu from scratch.
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.
Naruto would become even more of a powerhouse. His already strong will and determination, combined with Saiyan battle instincts, would make him nearly unstoppable. He might become a bit more brash in combat, like a typical Saiyan. Hinata, on the other hand, would gain more confidence. Her gentle nature could be tempered with the fierce Saiyan spirit, making her a more assertive fighter.
Their relationship could become more intense. Naruto's Saiyan traits might make him more protective of Hinata. For example, his increased sense of justice from the Saiyan side would make him even more determined to keep her safe from any harm.
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 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.
A possible storyline could involve Naruto discovering a new form of power that combines his chakra with Saiyan energy, leading to his Super Saiyan - like transformation. He might then face a new and extremely powerful enemy that only his new form can defeat. Along the way, his friends would be both amazed and a little worried about this new side of Naruto.
