If Sasuke tries to steal from Naruto in fanfiction, the story might take a dark turn. Naruto could become vengeful and go after Sasuke with all his might. This could lead to a series of battles across different locations. Meanwhile, the rest of the ninja world might start to take sides, some believing Sasuke has a good reason, while others stand firmly with Naruto. The stolen item could also be a key element that has the potential to change the balance of power in the ninja world, so many would be interested in it.
In fanfiction, if Sasuke tries to steal from Naruto, it could lead to a major conflict. Naruto might be deeply hurt, considering they are friends (or frenemies depending on the plot stage). This could trigger a chase or a battle between them, and other characters might get involved to either stop Sasuke or take sides.
Well, Naruto and Fem Sasuke's relationship could start with their mutual understanding of each other's pain. They've both had difficult pasts. Naruto, being the lonely kid, and Sasuke, with his clan's tragedy. In a fanfiction, Fem Sasuke might be more in touch with her emotions. They could start as rivals still, but gradually, Naruto's unwavering determination to bring Sasuke back could turn into a deeper affection. Maybe during a mission together, they could share a moment of vulnerability and realize their feelings for each other.
Their relationship could develop through mutual respect. Naruto respects Sasuke's power and Sasuke starts to respect Naruto's unwavering spirit. Sai, as he spends more time with them, earns their respect too. This could lead to a deeper bond between the three.
Well, it could start with Sasuke joining the Akatsuki with the sole intention of protecting Naruto from within. He could form alliances with some of the less - evil members who might also have a grudge against those who want to harm Naruto. For example, he could team up with Zetsu, who has his own motives and might be persuaded to help protect Naruto in exchange for something.
One way it could develop is that the baby has some special powers that attract the attention of villains. Naruto and Sasuke then have to protect the baby while also trying to teach it right from wrong. As the baby grows, it could start to have its own dreams and goals, which might be different from what Naruto and Sasuke expect, adding more drama to the story.
The Hidden Leaf Village would surely launch a rescue mission. This would involve characters like Kakashi, Sakura, and the other ninja. Their efforts to find Naruto would be a major part of the story. Meanwhile, Sasuke might be moving Naruto from one location to another to avoid being caught, which would add more twists and turns to the plot.
Often, it develops through shared hardships. For example, they might be captured by a powerful enemy and have to escape together. During this time, they learn to trust each other more deeply.
Naruto might initially be shocked and confused. He has always considered Sasuke as a friend, so Sasuke's sudden attempt on his life would be a huge blow. He may try to talk to Sasuke first, to understand why he is doing this.
In the original, Naruto and Sasuke had a very competitive and often strained relationship. But in a Dark Naruto and Fem Sasuke fanfiction, their relationship could start off with more of an understanding. Since Fem Sasuke might be more empathetic than the original Sasuke, she could see the pain that Dark Naruto is going through and try to help him from the start. Instead of the rivalry, it could be a partnership based on mutual respect and a shared sense of being different from the norm in the village.
In the fanfiction world, it could be due to a deep emotional bond between Naruto and Sasuke. Their connection could be so strong that in a moment of extreme danger or a spiritual awakening, Sasuke's Sharingan essence is transferred to Naruto. For example, if Sasuke was on the verge of death and his chakra merged with Naruto's in a desperate attempt to save Naruto, the Sharingan could be part of that transfer. This would also add a whole new layer to their relationship and Naruto's character development as he would have to learn to control this new power.
