In this fanfiction, the story could take an interesting turn if Naruto and Sasuke have different ideas about what kind of wife the character should have. Naruto might think a cheerful and energetic woman would be perfect, while Sasuke would lean towards someone more reserved and intelligent. Their conflicting opinions could lead to a series of humorous and heart - warming events as they try to find the right match for their friend.
One way could be through a kekkei genkai transfer jutsu. If a powerful ninja, perhaps an old hermit with knowledge of ancient jutsus, decides to transfer Sasuke's Sharingan to Naruto for the greater good of the village. This jutsu might be risky but in the world of fanfiction, anything is possible.
The plot could involve the main character having some specific requirements for a wife. Naruto and Sasuke then embark on a journey to find such a woman. They could travel to different villages in the ninja world. Along the way, they encounter various challenges, like rival ninja groups who try to stop them because they don't want their women to be taken away.
Perhaps Fem Sasuke is brainwashed by an enemy. This enemy could use some sort of mind - control jutsu on her. They plant false memories or ideas in her head, making her believe that Naruto has become a danger. She then betrays him, but as the story progresses, she starts to break free from the mind control and realizes her mistake.
In some fanfictions, Naruto's determination helps break the ice between Sasuke and Sakura. Naruto's unwavering belief in their friendship encourages Sasuke to open up more, and Sakura, with her growth in medical ninjutsu and her own strength, becomes more confident around them. They start to have more friendly banter and support each other on missions, much like a real team should.
One type could be a fire - based curse mark. Given Sasuke's natural affinity for fire - style jutsu, a fire - based curse mark might enhance his existing abilities to an extreme level. It could make his fire jutsu more intense and uncontrollable at first. For Naruto, a wind - based curse mark could be interesting. Since he already has strong wind - style techniques, this curse mark might give him the ability to create more powerful and unique wind attacks, like a tornado - like jutsu with a dark twist.
In fanfiction, Naruto and Sasuke might become friends when they have to protect someone important to both of them. Let's say it's a young orphan who reminds them of their own difficult pasts. Naruto's positive attitude and Sasuke's protective nature would kick in. They would work together to keep the child safe. Through this shared experience and the emotions it stirs, they start to see each other in a new light and become friends.
In some fanfictions, Naruto might be indifferent to Sasuke if the author wants to explore a different dynamic. Maybe Naruto has had a life - changing experience that makes him focus more on other things like the well - being of the village as a whole rather than just Sasuke. It could also be due to a misunderstanding or a new friendship that overshadows his previous intense connection with Sasuke.
There are indeed some 'Naruto cheats on Sasuke' fanfictions. These are usually created by fans who want to experiment with different relationship dynamics. But from a traditional Naruto fan's perspective, it can be quite jarring as Naruto and Sasuke's relationship is a cornerstone of the series. Their relationship is built on years of battles, reconciliations, and a shared understanding of each other's pain. So these fanfictions are a very different take on their relationship.
In a fanfiction scenario, perhaps a love interest could be a cause. If Naruto fell in love with someone who had a strong hatred for Sasuke, and Sasuke refused to make amends or change his ways for Naruto's sake, it could create a rift. Also, if Sasuke's power-hungry nature made him try to steal Naruto's power source, like the Nine - Tails, it would be a huge betrayal and could result in Naruto severing their bond.
Perhaps in a fanfiction, Sasuke discovers a new and extremely dangerous power that he can't control and it starts to endanger Konoha. Naruto tries to stop him but in the heat of the battle, accidentally kills him. Overwhelmed with guilt and feeling that the village will never understand, Naruto leaves. But this is a very different take on their relationship and the Naruto world as a whole.
