One possibility is that Itachi finds Naruto in a vulnerable state and decides to take him in as a pet. Naruto might initially resist but then come to understand Itachi's motives. It could be a story of Naruto learning from Itachi's skills and wisdom while being in this unique 'pet' relationship.
Naruto's character could become more reserved. Since he is in a subservient role as a pet, he might learn to be more patient and observant, like Itachi. His brashness might be toned down as he follows Itachi's lead.
In many Naruto fanfictions, the ages of Naruto and Itachi can be quite flexible. Sometimes, authors might change their ages to create different story dynamics. For example, an author could make Itachi younger to explore a different version of his character development, perhaps showing him still in the early stages of his ninja training while dealing with the dark secrets of the Uchiha clan. Naruto's age might also be adjusted, like making him older to be in a more equal power dynamic with Itachi from the start.
Another teammate often included in fanfiction is Kakashi. Some fanfictions might create scenarios where Itachi and Kakashi interact during missions or even in their off - time. It could be interesting to see how their different skills and personalities clash or complement each other. For example, Kakashi's laid - back attitude contrasted with Itachi's more serious and reserved nature.
Naruto would adapt to Itachi's life in several ways. Socially, he'd have to get used to Itachi's connections and rivalries. For instance, his relationship with Kisame would be different as Naruto. He might try to influence Kisame in a more positive way. Emotionally, he'd have to deal with Itachi's internal struggles. Itachi had a lot of guilt and secrets, and Naruto would have to either come to terms with them or find a way to resolve them. And in terms of combat, he'd practice Itachi's signature moves over and over to make sure he could use them effectively in battle.
In fanfiction, having Naruto as Itachi's partner can lead to some really interesting scenarios. Naruto's positive and determined nature could contrast with Itachi's more reserved and burdened personality. They might work together to uncover secrets within the ninja world or face powerful enemies. Naruto could also learn a great deal from Itachi's skills and wisdom.
I'm not entirely sure if there is a specific well - known fanfiction with that exact premise. But considering how fanfiction works, someone may have written a story like this. It could explore some really complex emotions and new storylines. Imagine Naruto growing up with Itachi's teachings and how that would shape his view of the ninja world, and also how the other characters would react to this new relationship. It would be a very different Naruto story for sure.
In some fanfictions, yes, itachi can be written as Naruto's father. Fanfiction allows for a lot of creative reinterpretations of the original Naruto story. Writers might create this relationship to explore different character dynamics and plotlines.
Itachi's protectiveness can make Naruto more confident. Knowing that someone as powerful as Itachi has his back gives Naruto a sense of security. This allows him to take more risks in his training and battles, which in turn helps him grow stronger. For example, he might attempt more difficult jutsu without fearing too much about the consequences of failure because he believes Itachi will step in if things go really wrong.
Itachi's teaching style, being calm and strategic, would likely have a profound impact on Naruto's growth. He might teach Naruto to be more patient and observant. For example, Itachi could show Naruto how to analyze an opponent's moves before acting impulsively, which is a big change from Naruto's usual head - first approach.
