Yes, there might be such a fanfiction. In the Naruto fandom, with its large and diverse range of fan - created works, various out - of - canon scenarios are explored. However, this goes against the original storyline where Hinata and Neji have a complex relationship that is more about growth, understanding, and family bonds rather than such a violent act.
Naruto and Neji's friendship in fanfiction often delves into their past traumas. Naruto understands Neji's pain of being in a rigid clan structure, and Neji realizes Naruto's loneliness from being an outcast as a child. This mutual understanding cements their friendship. They support each other in battles, with Naruto relying on Neji's strategic mind and Neji depending on Naruto's raw power and determination.
Their relationship could develop from initial distrust to mutual respect. Naruto might be the one to break the ice with his friendly and outgoing nature, while Neji would slowly open up as he sees Naruto's growth and determination.
One common element is Naruto's growth. He usually has to reach a new level of power or understanding to defeat Madara. For example, he might gain a new jutsu or a deeper connection with his inner chakra.
Another possibility is that Naruto could defeat Kakashi if the latter was in a weakened state. Maybe Kakashi had just come out of a tough battle with other powerful enemies and was low on chakra. Meanwhile, Naruto was at his peak, full of energy and ready to fight. In this situation, Naruto's sheer determination and his own strong abilities could lead to his victory.
In a more psychological approach, Naruto could have grown so much as a character that he no longer fears Kakashi's reputation. This new - found confidence could change the dynamics of their fight. He might be able to read Kakashi's moves better and anticipate his attacks. Combined with his own ever - improving skills, Naruto could defeat Kakashi in this state of mental superiority.
There are fanfictions where Naruto teams up with other powerful characters like Jiraiya. Together, they come up with a plan to trap Orochimaru and then Naruto delivers the final blow. Naruto might use his Sage Mode skills, if he has them in that particular fanfiction, in combination with Jiraiya's knowledge and power to outwit and defeat Orochimaru.
Well, one way Naruto could defeat Iwa in fanfiction is through strategic alliances. He could team up with other ninja villages or powerful individuals who have a grudge against Iwa. Together, they could plan elaborate attacks and outwit Iwa's military strategies. Also, Naruto's ability to inspire others might lead his allies to fight more bravely, giving them an edge in the battle.
Neji might gain a significant boost in power. Without the seal suppressing him, his chakra flow could become more natural and stronger. He could potentially unlock new abilities or improve his existing ones, like his Gentle Fist technique becoming even more potent.
In many fanfictions, Naruto might use his unique chakra, perhaps enhanced by his Uzumaki heritage or the Nine - Tails' power. His strong will and connection to his friends could also play a role, allowing him to find a way to break the seal through sheer determination and his belief in Neji's potential.
