There could be a fanfiction where Sasuke and Naruto accidentally travel back in time and meet a young Itachi. They then try to change certain events that happened in Itachi's life to prevent the tragedies that followed. This would involve them trying to understand Itachi's situation better, and also dealing with the challenges of time travel. They might face opposition from those who want to keep the timeline intact, but their determination to save Itachi and improve the future could drive the story forward.
One interesting storyline could be a story where Sasuke, Naruto and Itachi have to team up against a new, powerful enemy. They put aside their differences and combine their unique skills. Naruto's positive energy and powerful jutsu, Sasuke's sharingan - based techniques, and Itachi's strategic mind make them a formidable force. This kind of story could explore their growth as characters and how they learn to trust each other more deeply.
A great fanfiction plot could be set in an alternate universe where Itachi didn't have to make the difficult choices he did in the original story. In this universe, he, Sasuke and Naruto could train together from a young age. This would lead to a different dynamic between them. Sasuke wouldn't be as consumed by revenge, and Naruto would have two very strong comrades from the start. It would be interesting to see how their relationships develop and how they influence the ninja world in this new scenario.
Another storyline could be a time - travel fanfiction. Sakura somehow travels back in time and meets a young Itachi. She tries to prevent the Uchiha massacre by working with Itachi. In this process, she might also learn more about the Uchiha clan and their secrets, which she can later use to help Naruto in their present - day battles.
In a more complex story, Female Itachi could be part of a prophecy related to Naruto. The two of them are fated to join forces to defeat a greater evil. Their journey involves them learning about each other's powers and pasts. Female Itachi might have her own secrets about the Uchiha clan that she reveals to Naruto as they grow closer in their fight against the common enemy.
Perhaps a fanfiction where Naruto and Sasuke are in a bit of a feud again, and Sai has to play the mediator. Sai, with his detached yet observant nature, tries to make Naruto and Sasuke see each other's points of view. This could lead to a series of events where they all grow as characters, learning about friendship, forgiveness, and the power of unity.
One great fanfiction is 'The Bonds Beyond Blood'. It delves deep into the complex relationships between Sasuke, Naruto, and Itachi. It shows how Naruto's unwavering friendship tries to reach Sasuke even as he is haunted by Itachi's actions. Another is 'Sasuke's Redemption Path' which has a lot of emotional moments between Sasuke and Naruto as they both come to terms with Itachi's true motives.
Some fanfictions focus on Sasuke finally understanding Itachi's true motives completely. For example, in a story, Sasuke discovers a hidden diary of Itachi that reveals all his selfless sacrifices for the village and for Sasuke. This leads to a very emotional reconciliation between them.
One interesting storyline could be Naruto finding baby Sasuke alone in the forest and deciding to take care of him. Naruto, with his big heart, would do his best to protect Sasuke from any harm that might come their way, like facing off against wild animals or rogue ninjas.
Another unique idea is time - travel. There are fanfictions where Sasuke travels back in time and tries to prevent the tragedies that happened to his family. This creates a whole new set of interactions with Itachi and Naruto.
One common theme is redemption. For example, Itachi's actions are often explored in a way that he tries to atone for his past deeds. Naruto usually helps in this process as he believes in the good in people.
A plot could involve Itachi coming back to life and trying to make amends with Sasuke while also having to deal with Naruto's newfound power. Itachi sees the bond between Naruto and Sasuke and tries to help them strengthen it further for the sake of the Hidden Leaf Village. He could train them in some of his unique jutsu.
Well, in some fanfictions, Itachi might seem to be cheating on Naruto in the sense that he's forming closer alliances with other characters for strategic purposes. For example, he could be getting involved with another ninja clan to gain information or resources for the greater good, but Naruto misinterprets his actions as being unfaithful in their friendship.
