If Naruto was a full - blooded Uchiha in fanfiction, it would completely rewrite his story. His connection to the Uzumaki clan would be gone, and instead, he would be part of the Uchiha legacy. He might have to deal with the Uchiha's dark past, like the massacre. His ninja path would be different, perhaps more focused on the Uchiha's style of combat and their unique jutsu. And his interactions with other characters, especially those related to the Uchiha like Itachi, would take on new meanings.
In fanfiction, if Naruto were a full - blooded Uchiha, it would have far - reaching implications. Firstly, his appearance might change to fit the Uchiha look more. His abilities would be centered around the Uchiha's genetic gifts, such as the Sharingan and Fire - style jutsu. His role in the village could also be different. He might be more involved in Uchiha - related affairs and have a different standing among the clans. Moreover, his emotional and mental development could be influenced by the Uchiha's values and history, which are quite different from the Uzumaki's. This would lead to a completely different Naruto, both in terms of his abilities and his place in the Naruto universe.
It would mean a major shift in his character dynamics. For one, his relationship with Sasuke would be on a different level as they would be from the same clan. Also, he would likely have access to the Sharingan and all its powers from the start. This would change how he approaches battles and his overall growth as a ninja.
In some fanfictions, Naruto could be made a full - blooded Uchiha through various creative plot devices. It might involve things like magic or some sort of genetic manipulation that rewrites his origin story. However, this is completely different from the original Naruto story where he is an Uzumaki.
If Naruto were a full - blooded Saiyan in fanfiction, his entire story would change. His growth would be different. Instead of chakra, he'd have ki. He could sense other powerful beings more easily. His training would likely involve more physical combat and less of the ninja - style training. Also, his Saiyan heritage might make him more of an outcast in the ninja world initially, as he'd be so different from everyone else.
Yes, there are some fanfictions out there with this concept. It's a really interesting take as it completely changes Naruto's heritage in the Naruto universe. It can lead to all kinds of different storylines, like how he interacts with the Uchiha clan members, and how his new identity affects his relationships with Sasuke and others.
The Uchiha might initially be filled with anger. Their trust in Naruto, if it was there before, would be completely shattered. They could start to plot revenge against Naruto, believing that he has wronged them. This could lead to a lot of tense moments in the fanfiction as the Uchiha gather their strength and resources.
A possible plotline is that Naruto's Uchiha blood gives him unique insights into the Sharingan and its powers. He might be able to unlock new forms of the Sharingan that no other Uchiha has. This could lead to him being hunted by other villages who fear his power. In the village, he might have to fight against the prejudice that still exists towards the Uchiha. His friendship with other characters like Shikamaru and Choji could also be affected as they now see him as an Uchiha with a different status.
If Naruto saved the Uchiha clan, the story of the Hidden Leaf Village would be rewritten. The history of the Uchiha's massacre would no longer be a dark stain on the village's past. The Uchiha would contribute their unique skills and abilities to the village's development. For example, their Sharingan abilities could be used for better security or in battles against common enemies. There would also be a change in the relationships between characters. People who were once enemies of the Uchiha might have to learn to work with them.
In this kind of fanfiction, Naruto might grow up with a very different set of skills and values. He could be more attuned to the Uchiha's Sharingan - related techniques. Maybe he'd be more brooding like the typical Uchiha, instead of his usual energetic self. Also, his relationship with Sasuke would be really interesting, as they would be more like brothers from the start rather than rivals.
Well, he might gain access to the Uchiha's powerful jutsu. For example, he could learn Sharingan techniques earlier. And he would probably grow up with a different sense of family and loyalty, more in line with the Uchiha values.
Well, one possibility is that he'd have the Sharingan from the start. He might grow up with different training methods, more focused on Uchiha techniques. Maybe he'd be more of an outcast in the village not just because of the Nine - Tails, but also because of the Uchiha's reputation. And his relationship with Sasuke would be completely different, perhaps they'd be rivals in a whole new way, competing over who is the true Uchiha heir in terms of power and abilities.
He would be more aggressive. Saiyans are known for their warrior - like nature, so Naruto might be quicker to anger and more eager to fight.
