In some fanfictions, Naruto defeats Orochimaru by mastering a new and powerful jutsu. This jutsu could be something he discovers on his own during intense training, allowing him to overpower Orochimaru's snake - like techniques.
Well, it varies in fanfics. Sometimes Naruto could have outsmarted Orochimaru with strategic planning and teamwork with his friends.
Well, in some versions, Naruto might use his new and improved Rasengan techniques. He could have combined it with his Sage Mode powers to overpower Orochimaru. Maybe he also uses his quick thinking and the element of surprise, since Orochimaru is always so full of his own schemes.
In this kind of fanfiction, Naruto might have used his new and powerful jutsu that he developed secretly. Maybe it was a super - enhanced Rasengan with some special chakra nature added to it, which was strong enough to overpower Orochimaru.
In some fanfictions, Naruto might gain the power to defeat Kaguya through intense training in a hidden realm. This realm could have special chakra - enhancing properties that allow him to reach new levels of power.
Naruto could be related to Orochimaru in a fanfiction through a family - like bond. Maybe Orochimaru has a past connection to Naruto's family that was previously unknown. It could be that Orochimaru had a debt to Naruto's father or some other relative, and this leads to an unexpected relationship where Orochimaru feels obliged to protect or guide Naruto in some way.
Some fanfictions might depict Naruto as having a deeper understanding of the chakra system than ever before. He could have found a way to disrupt Madara's connection to the chakra source, or maybe he was able to use his own chakra in a way that nullified Madara's powerful jutsus. Also, Naruto's experience from all his previous battles might have led him to anticipate Madara's moves and strategies, allowing him to stay one step ahead and ultimately defeat him.
In fanfiction, Naruto might be shown as having a similar thirst for knowledge as Orochimaru. He could be constantly seeking out new jutsus and ways to improve his skills, just like Orochimaru was always interested in expanding his power through knowledge.
Well, Orochimaru's immortality would mean that his influence would be long - lasting. He could continue to conduct his unethical experiments over a very long period. This might lead to the creation of new and dangerous ninja techniques or even new forms of life. In the long run, it could change the way ninja are trained and how the ninja world views power and knowledge. For example, some might start to see immortality as the ultimate form of power and strive for it at all costs. Naruto and his friends would have to constantly be on guard against Orochimaru's schemes.
Well, in some fanfictions, Orochimaru might use some forbidden jutsu. He could have combined his knowledge of resurrection techniques with some unique chakra sources. Maybe he found a way to reverse the death process by using the power of the snakes he has a connection with. For example, he could have used the regenerative abilities of the snakes' chakra to bring Naruto back to life.
In certain fanfictions, Naruto could approach the paperwork in a more diplomatic way. He might convince others in the village, like his friends or some of the ninja clans, to help him with the paperwork. By using his charisma and leadership skills, which he has developed over time, he gets everyone to pitch in. And with their combined efforts, they manage to defeat the mountain of paperwork. After all, Naruto is not just a powerful fighter but also a great leader who can inspire people to work together.
