If Naruto were Itachi's twin in fanfiction, it would have a huge impact on the plot. Naruto would grow up with different values perhaps, influenced by the Uchiha clan's way of thinking. His goal might not be just to become Hokage in the traditional sense. He could be more focused on avenging the Uchiha clan or restoring its honor. The power balance in the village would shift too. The Uchiha clan might have a stronger standing with Naruto being part of it. And the mystery surrounding Itachi's actions would take on a new meaning for Naruto, as he'd be directly related. He might be more involved in uncovering the truth about Itachi's motives much earlier in the story.
If Naruto was Itachi's twin brother in this fanfiction, Sasuke's relationship with both of them would be extremely complex. Naruto would be Sasuke's family in a different way than just a friend. He might be more protective of Sasuke from the start. And Sasuke would view Naruto not just as a rival to surpass but also as part of his family's mystery. Since Itachi was Sasuke's brother, Naruto being Itachi's twin would put Naruto in a strange position in Sasuke's eyes, perhaps a mix of suspicion and a longing for family connection.
Well, first of all, his abilities should set him apart. He could have a natural talent for genjutsu, while Naruto struggles with it. His personality traits can be explored in relation to Naruto. If Naruto is the sunny optimist, the twin could be the brooding type, with a darker sense of humor. His relationships with the other villagers would also be a factor. He might not be as well - liked as Naruto at first, but as the story progresses, he earns their respect in his own way. Additionally, his reactions to Naruto's fame and how he carves out his own identity within the shinobi world are crucial for developing his character.
As the story progresses, they could start to realize that they are stronger together. They might face a common enemy that forces them to work as a team. Through shared experiences like training together and fighting side by side, their relationship turns into a strong bond of brotherhood.
I really like 'Itachi's Unseen Love'. In this fanfic, Itachi's love for Sasuke is portrayed in a very emotional way. It shows how Itachi sacrificed so much for his younger brother. The writing is very engaging and it makes you feel the depth of their relationship.
The twin brother's character might be developed based on his past. If he had a difficult childhood, it could make him more reserved or cautious. But as he gets to know Naruto and Sakura, he starts to open up. He could start as a loner type, but as he gets involved in their adventures, he becomes more social and confident. He might also develop his character by exploring his own unique abilities and how they can be used for good.
Another plot point is often family drama. The Uchiha clan has a lot of internal politics and expectations. So, the OC and Itachi might face different pressures from the clan. Maybe the clan favors Itachi more, and the OC has to struggle to prove himself. Also, their relationship with their parents can be a big part of the story. The parents might have different expectations for each of them, which can cause tension. And finally, there could be a plot point where the OC has to step in and protect Itachi or vice versa, especially when Itachi is given the difficult task of massacring the clan. The OC's reaction to this event and how he tries to save his twin or deal with the aftermath is often explored.
A good way to create a compelling character for the twin brother is to make his powers have a cost. For instance, every time he uses a powerful Devil May Cry - style attack, it drains his chakra like in Naruto. This creates internal conflict as he has to balance when and how to use his abilities. Also, give him relationships that are complex, like having a love - hate relationship with a character from the Naruto world who is suspicious of his Devil May Cry powers, and at the same time, having a mentor - like figure from the Devil May Cry world who is trying to help him control his Naruto powers.
Sure. A lot of these fanfictions delve into how Naruto's life could be different if he was actually Itachi's brother. For example, they might change the way Naruto is treated in the village, or how his ninja training progresses. Some also explore how the Uchiha clan massacre would be affected and what role Naruto could have played in preventing it or dealing with the aftermath.
One possible fanfiction idea could be that Hinata's twin brother is a prodigy in a different ninja art than Hinata. He might be more focused on offensive taijutsu techniques, while Hinata is known for her gentle fist. This could create an interesting dynamic within the Hyuga clan as they both grow and develop their skills.
