In a Naruto joins the Uchiha clan fanfiction, he could be adopted by an Uchiha. For example, if Sasuke had a change of heart early on and decided to bring Naruto into the clan. Naruto would then be exposed to the Uchiha's dark past and their thirst for revenge. He could use his own positive attitude to try and change the clan's perspective. And he'd surely have to train hard to keep up with the Uchiha's high standards in combat and ninja skills.
Perhaps in this fanfiction, a powerful enemy forces the Uchiha clan to accept Naruto in order to gain strength. Naruto, being the hero he is, would bring his own set of skills and values. He could teach the Uchiha about friendship and loyalty in a different way. With his chakra reserves and his ability to learn quickly, he could master the Uchiha techniques and even help revive some of the lost arts. His presence might also bridge the gap between the Uchiha and the rest of the village.
In a Naruto joins good Akatsuki fanfiction, the story could start with Naruto seeing the potential good in the Akatsuki. Maybe he realizes that some of their members were just misled or had no other choice. So, he decides to join them to reform the group from the inside. Naruto's positive attitude and his never - give - up spirit could inspire the Akatsuki members. He might start training with them and sharing his own ninja techniques, which could lead to the creation of new and more powerful combined techniques for the group as a whole.
The fanfiction could explore how Naruto Uchiha's character changes as the son of Zeus. He might become more confident, yet also more burdened. His relationships with his family and friends could be completely transformed. For instance, Sasuke might see him as a threat now that he has divine heritage. And Naruto would have to prove himself not just as a ninja, but as a worthy son of Zeus, perhaps by going on a quest to retrieve a powerful artifact that is important to both the ninja and godly worlds.
Well, one possibility is that Naruto would be trained in the unique Uchiha techniques. He might learn how to use the Sharingan in ways that no one expected. Also, he could gain a new family within the Uchiha clan, which would change his whole perspective on life and belonging.
It could be that in this fanfiction, Naruto is on a mission with an Inuzuka member and they get into a difficult situation. Naruto shows extraordinary courage and loyalty during this mission. This impresses the Inuzuka clan so much that they start to consider him as one of their own. He then starts training with them, learning how to communicate better with the Inuzuka dogs and using their clan - specific jutsu, and he also becomes part of their family - like structure within the clan.
Well, it could mean Naruto adopting the Uchiha's sense of pride. He might start showing off his skills more like an Uchiha would, with a certain arrogance. Also, he could become more brooding and mysterious, similar to Sasuke, an Uchiha. Maybe he'd even start wearing clothes in the Uchiha style, with a dark color scheme.
Well, in this fanfiction scenario where Naruto kills the Uchiha clan, it would mean the end of the Sharingan bloodline in a very unexpected way. This would have huge implications for the ninja world. Without the Uchiha, there would be no potential for the Mangekyou Sharingan or the Eternal Mangekyou Sharingan. The balance of power in the ninja world might shift as the Uchiha were quite powerful. And Naruto himself would be a very different character. He's always been about protecting and saving people, so this act would make him a much darker and more complex figure, almost an anti - hero.
One possible plot twist could be that Naruto, being adopted by the Uchiha clan, discovers a hidden connection between his own family and the Uchiha. Maybe his parents had some secret pact or relation with the clan that was unknown before. This could lead to a whole new set of adventures as he tries to uncover the truth.
One possible plot twist could be that Naruto discovers his Uchiha heritage through a long - lost scroll or a prophecy. This would completely change his relationship with Sasuke, as they would now be related in a way. Another twist could be that Naruto has to deal with the dark side of the Uchiha legacy, like the Curse of Hatred, which has been passed down in the clan.
If Naruto joins the Uchiha clan, his character would develop in several ways. He would have to adapt to the clan's hierarchical structure. This could make him more respectful of traditions. His relationship with Sasuke would take on a whole new dimension. They could become more like brothers within the clan, and Naruto would have a stronger sense of family. Also, his understanding of power and responsibility would grow as he learns about the Uchiha's power - hungry past and how it led to their downfall.
One possibility is that Naruto would have to adapt to the unique abilities of the Aburame clan. Since the Aburame are known for their insect - related jutsu, Naruto might struggle at first to work in harmony with the bugs. For example, he'd need to learn how to communicate and control them, which is very different from his normal combat style of using shadow clones and rasengan. He could also bring a new perspective to the clan, with his never - give - up attitude inspiring the more reserved Aburame members.
