One interesting Sasuke x Hinata Madara fanfic is 'The Unlikely Bond'. It explores a unique scenario where Sasuke, Hinata and Madara are brought together in a complex plot. The characters' personalities are well - written and the story has a good flow.
Finding a good 'madara x hinata x sasuke fanfic' depends on your personal taste. Some people like fics that focus more on the emotional relationships between the characters, while others might prefer action - packed stories. You can start by searching for these character names in combination on different fanfic sites and then explore the ones that seem the most appealing based on their summaries.
One possible plotline could be that Madara, Hinata and Sasuke are forced to team up for a mission. Along the way, they start to understand each other better and develop unexpected bonds. Maybe Hinata's kind nature starts to soften Madara's hardened heart, and Sasuke is caught in the middle of this new dynamic.
One key element is the exploration of new relationships. Since Sasuke, Hinata and Madara don't have a traditional relationship in the original work, fanfics get to create unique bonds between them. For example, they might be forced into an alliance in a fanfic and have to learn to trust each other.
Another theme could be the power dynamic. Madara is a very powerful character, and Hinata has her own unique abilities. Fanfics might play with how their powers influence their relationship, like how they protect each other or train together.
I'm not sure about a specific 'itachi x hinata x sasuke fanfic' to recommend. You could try searching on fanfiction websites like Archive of Our Own. They usually have a wide variety of fanfics, and you might be able to find one that involves this particular pairing.
Power is a common theme. Both Madara and Sasuke are extremely powerful characters, so fanfics often explore how their powers interact or complement each other. Another theme is redemption. Madara has a complex past, and Sasuke has his own journey of redemption in the original story, so this can be explored in their relationship in fanfics.
Love triangles also appear quite often. Given Hinata's feelings for Naruto and the complex relationship between Naruto and Sasuke, writers play around with the idea of how these relationships can develop in different ways, adding a touch of romance and drama to the stories.
I really like 'The Trio's Destiny'. It starts with a strange event that binds Naruto, Hinata, and Sasuke together. As the story progresses, their individual goals start to blend with their newfound connection. It shows how their different personalities can either clash or complement each other in a really interesting way.
Maybe in the fanfic, Itachi returns from the dead in some sort of magical or mysterious way. Sasuke is initially conflicted about his brother's return, and Hinata, with her kind heart, tries to bridge the gap between the two Uchiha brothers. Along the way, feelings start to develop between all three characters, and they must navigate their new relationships while also dealing with threats to the Hidden Leaf Village.
