Well, if Naruto takes Itachi's place, the Akatsuki would be in for a big surprise. Naruto's combat style and his never - give - up attitude would change the dynamic within the Akatsuki. He might try to reform some of the members from the inside, using his talk - no - jutsu. Also, his relationship with Sasuke would be completely flipped. Instead of being Sasuke's rival and friend, he would be in a position where he has to keep secrets from Sasuke, which could lead to some really intense and different interactions between them.
In a fanfiction where Naruto takes Itachi's place, the story would likely deviate greatly from the original plot. Naruto's values and goals are different from Itachi's. Naruto would probably focus on protecting the village while also trying to find a peaceful solution for the Uchiha. He may not be as stealthy as Itachi, but his raw power and determination could make up for it. His presence in the Akatsuki could also lead to different alliances and rivalries within the organization. For example, he might befriend some members who were originally Itachi's enemies, and his actions could potentially split the Akatsuki into different factions based on their views of Naruto.
One possible outcome is that Naruto, being in Itachi's place, might have a very different approach to dealing with the Uchiha clan situation. Naruto is known for his strong belief in redemption and friendship. He could have tried to reason with the Uchiha clan instead of the events that Itachi had to go through. This might have led to a different relationship between the Uchiha and the village.
In such a fanfic, Naruto might have to carry out Itachi's mission to protect Konoha in a different way. He may use his own unique ninja skills and positive attitude to face the Akatsuki. For example, instead of using Itachi's Sharingan techniques, he would rely on his Shadow Clone Jutsu and Rasengan variations.
Well, one possibility is that the 'new' Naruto, who is actually the original Naruto in a different role, could change the course of events in the Hidden Leaf Village. Maybe he would approach missions and training in a completely new way, leading to different power-ups and relationships with his comrades.
In this fanfiction, Itachi might take Naruto for various reasons. Maybe he sees some potential in Naruto that he wants to cultivate away from the academy's normal teachings. It could also be part of a larger plan to protect Naruto from unseen threats in the academy environment.
The storyline would change a lot. For starters, Naruto doesn't have the Sharingan like Itachi. So, all the battles and strategies that relied on Itachi's Sharingan abilities would be different. Naruto would have to rely on his own skills, like the Rasengan and his Sage Mode. Also, Naruto's interactions with the other characters in Itachi's world would be different. People in the Akatsuki might not trust him as easily as they did Itachi, or they might be more curious about him because he's so different.
One thing that could happen is that Naruto's influence might make Itachi more open about his feelings. Itachi has always been a very private person, but Naruto's outgoing and empathetic nature could break down those walls. They could also combine their abilities in combat in unique ways. Naruto's Rasengan and Itachi's Fire - Style jutsu could create some really cool and powerful attacks.
Well, Naruto might be shocked at first. He'd probably notice the resemblance to Itachi right away. And then he'd start thinking about his own relationship with Itachi.
In fanfiction, if Naruto takes Madara's eyes, he might gain incredible new powers. For example, he could potentially combine the power of the Sharingan or the Rinnegan with his own Sage Mode. This could make him an even more formidable opponent, able to predict attacks more accurately and use powerful genjutsu.
In this fanfiction, Naruto might gain some unique jutsu skills from Itachi. Itachi is extremely powerful, so he could teach Naruto advanced genjutsu or ways to better control his chakra. For example, Naruto might learn how to quickly break free from strong genjutsu attacks, which would be a great advantage in battles against tough opponents.
Perhaps Itachi sees Naruto as a key to unlocking some hidden power or knowledge. He could be planning to train Naruto in some way, away from the influence of the village. This would be a strange turn of events considering their previous interactions.
There could be a situation where the inn is under attack by a common enemy. Itachi, Sasuke and Naruto have to put aside their differences and work together to defend it. They use their unique skills - Itachi's genjutsu, Sasuke's fire - based jutsu and Naruto's shadow clones - to fend off the attackers. This experience bonds them in a new way and they leave the inn with a newfound respect for each other.
