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.
They could develop a mentor - mentee relationship. Itachi uses his knowledge of the Sharingan to teach Naruto new combat techniques. As they train together, they bond over their shared experiences of loss and their desire to protect the people they care about. Naruto might also help Itachi come to terms with his past actions and find some peace within himself.
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.
A third idea is that in a post - war scenario, Naruto and Female Itachi are part of a group rebuilding the ninja villages. They have to work together to allocate resources and help the survivors. At first, there are tensions because of the different clans they belong to. However, as they interact more, they realize they have a common goal of creating a better future for all ninjas. They might face challenges from other ninja groups who oppose their ideas of unity, but together they stand strong and form a bond that is both a friendship and a partnership in the reconstruction efforts.
Definitely include Obito. His complex relationship with the Uchiha clan and his own history with the Anbu - like Akatsuki could create some interesting plot twists. Additionally, Kurenai could be added. She could be involved in a mission where she has to work with Itachi and Naruto. Her genjutsu skills might come in handy during a crucial part of the story. And don't forget about Rock Lee. His determination and unique fighting style could add some action - packed scenes to the fanfiction, especially if he gets involved in a mission with Itachi and Naruto.
Yes, there are likely such fanfictions. Many fanfiction writers like to explore the idea of Itachi coming back to life with his memories intact. This allows for interesting character interactions, especially with Naruto. Itachi could use his wisdom and skills once again, and his relationship with Naruto could further develop in new and unexpected ways.
