Sasuke is often a popular character in these fanfictions. He might play a role in helping Naruto against Madara or have his own motives during their battle. Kakashi can also be a prominent figure, perhaps using his Sharingan in a crucial moment to assist Naruto. Another popular character could be Hashirama, as his connection to Madara is a key part of the original story and can be further explored in fanfiction.
One interesting plotline could be Naruto discovers a new form that gives him an edge over Madara. For example, a form that allows him to nullify Madara's Sharingan abilities. Another could be Madara having a change of heart due to Naruto's unwavering belief in him. Maybe he starts to question his own motives for destruction.
In such a fanfiction, Naruto and Sasuke might win. They are both extremely powerful and their combined strength, like Naruto's Rasengan and Sasuke's Chidori, could overpower Madara.
In this kind of fanfiction, Naruto being 'godlike' gives him a huge advantage. He might have powers far beyond his normal capabilities. So, Naruto would likely win. He could use his super - enhanced Sage Mode, or maybe some new jutsu that he has acquired in this 'godlike' state to overpower Madara.
In this fanfiction, 'godlike naruto' might have the power of absolute healing. No matter how severe the injury, he could heal instantly. He could also have the power to absorb and redirect any chakra - based attacks that Madara throws at him. This would make him almost invincible in the fight against Madara.
In such fanfiction, Sakura might be depicted as more alluring and perhaps more bold in her interactions with Madara. Madara could be shown as having a certain charm that draws Sakura to him.
Choji can be an interesting addition. He has a long - standing friendship with Shikamaru and his unique eating - based jutsu can be a valuable asset in battles in the fanfiction. With Ino, he can provide some comical relief as well as a different type of fighting style. Also, Kakashi could be paired with them. His vast experience and diverse jutsu knowledge can guide Ino, Shikamaru and the others, and his laid - back but serious attitude can be a great influence on the group.
Sakura might also be paired with Shikamaru. She could be in need of Shikamaru's help when she is facing a medical emergency in a battle situation and Shikamaru uses his shadow blade to fend off the attackers while Sakura tries to save a wounded comrade.
Well, in fanfiction about Shikamaru and Kiba, their relationship can be explored in various ways. Shikamaru's laziness in a sense can be a foil to Kiba's eagerness. Maybe in some fanfics, they start off not getting along because of their contrasting natures. But as the story progresses, they learn to appreciate each other's strengths. They could be paired up in a team - like situation, where Shikamaru uses his intellect to guide Kiba's brute force in battles or tasks, making for an exciting read.
