Well, it could mean Naruto adopting the Uchiha's sense of pride. He might start showing off his skills more like an Uchiha would, with a certain arrogance. Also, he could become more brooding and mysterious, similar to Sasuke, an Uchiha. Maybe he'd even start wearing clothes in the Uchiha style, with a dark color scheme.
His relationship with Sasuke would be really different. Instead of trying to bring Sasuke back to the village as a friend, he might see Sasuke as a rival in a more intense way, like two Uchihas competing. With Sakura, he might be more distant, as the Uchihas are often more reserved in their emotions. And his relationship with Kakashi could become strained, as Kakashi has his own history with the Uchihas.
It could be Sasuke's sister, if there was one in the fanfiction world. She might share some of Sasuke's traits but also have her own unique personality that attracts Naruto.
In a Naruto act like Near fanfiction, Naruto could develop Near's attention to detail. He'd be more likely to notice small things that others miss, like hidden traps or the slightest change in an enemy's behavior. This would give him an edge in battles and missions. Also, his decision - making might become more based on careful thought rather than just gut instinct.
One possible plotline could be Naruto trying to mimic Kakashi's calm and collected demeanor during a difficult mission. For example, when facing a powerful enemy, Naruto might hold back his usual冲动 and instead analyze the situation like Kakashi would. He could start using Kakashi - style strategies, like setting up elaborate traps or using misdirection to gain an advantage.
Maybe he's on a secret mission. He could be trying to infiltrate an enemy group that Tobi was associated with. By acting like Tobi, he hopes to gain their trust and gather information.
A Naruto as an Uchiha prodigy fanfiction would likely involve Naruto having to adapt to a whole new set of powers. He might struggle at first, not being used to the Uchiha way of doing things. But as time goes on, he could combine his own unique skills with the Uchiha powers. For example, his shadow clone jutsu could be enhanced with the Sharingan's abilities. And his relationships with other characters, like Kakashi who has a connection to the Uchiha, would also change in fascinating ways.
One reason could be for strategic purposes. Itachi was a highly strategic ninja. So, in fanfiction, Naruto might act like him to outwit a particularly difficult enemy. For instance, when facing an enemy who is a master of deception, Naruto could adopt Itachi's calm and calculating demeanor to see through the enemy's tricks.
Maybe Naruto is put in a situation where he feels that Hiruzen's way of handling things is the best option. For instance, if there is a major crisis in the village that requires a more traditional and experienced approach, Naruto might choose to act like Hiruzen. Also, he could be influenced by the stories he has heard about Hiruzen and wants to fill his shoes in a way.
