One possible plot twist could be that Sakura discovers a hidden weakness of Madara's during the fight. Maybe it's a chakra point that, when struck, temporarily paralyzes him, giving her an upper hand.
The moment when Naruto first unleashes his new ultimate attack against Madara would be really exciting. Maybe it's a combination of his Rasengan and some kind of Sage power that creates a huge explosion of energy that Madara has to struggle to defend against.
Well, one possible plot could be that Naruto discovers a new jutsu specifically designed to counter Madara's powerful Sharingan abilities. This jutsu might be related to the Sage of Six Paths' power that he already has. With this new power, Naruto engages in a series of intense battles with Madara, each time getting closer to figuring out Madara's weaknesses.
In such a fanfiction, Naruto could potentially win by using his new Sage of Six Paths powers to their fullest. He might be able to overpower Madara's Rinnegan abilities. For example, Naruto could use his massive chakra reserves to create countless shadow clones and overwhelm Madara in a battle of attrition.
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.
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.
They would likely have a complex relationship. At first, they might be wary of Madara as he has been their enemy in the past. But as they train under him, they would start to respect his skills and knowledge. Naruto might try to understand Madara's motives and see if there's any good in him. Sasuke, having an Uchiha connection, might feel a stronger sense of kinship but still be cautious. Madara, for his part, would probably see them as tools at first but gradually develop a strange sort of respect for their growth.
In many fanfictions about Naruto fighting Sasuke during the Chunin Exams, it often showcases their intense rivalry. One common aspect is the display of new jutsus that they might have developed secretly. For example, Naruto could have a new form of the Rasengan, and Sasuke might have evolved his Chidori in some unique way. This makes the fight more exciting as it goes beyond what we saw in the original series.
Another theme is the clash of ideals. Sasuke has his own set of goals and beliefs which may not always align with the village's or Sakura's. Fanfictions often explore how this difference can lead to a fight, like in stories where Sasuke's thirst for revenge clashes with Sakura's hope for peace and unity in the village. This can make for a very engaging plot as they try to convince each other or just fight it out.
One interesting fanfiction could be where Sasuke and Sakura have a sparring match in a post - war Konoha. They both use their unique skills, Sasuke with his Sharingan - enhanced jutsu and Sakura with her superhuman strength. It shows their growth as shinobi and also their complex relationship.
