Maybe Naruto discovers a hidden scroll that has a spell or technique specifically for dealing with paperwork. He then uses this new - found knowledge to make all the paperwork disappear or transform into something more manageable, like a single small scroll that contains all the important information in a condensed form.
Another way could be that Naruto enters a special mental state, similar to when he taps into the power of the Nine - Tails. In this state, his mind works at an incredible speed, and he can read and process the paperwork at a superhuman rate. He can then make decisions and complete the necessary tasks in a fraction of the time it would normally take. This shows his ability to use his powers in unexpected ways even when it comes to non - combat situations like paperwork.
One consequence could be that the village runs more smoothly. With the paperwork out of the way, decisions can be implemented faster.
Perhaps he uses some ninja techniques like a shadow clone jutsu. He could make multiple clones to help him sort through and complete the paperwork quickly.
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.
In some fanfictions, there might be a scenario where Naruto and Zabuza are forced to team up against a common enemy first. During this time, Naruto learns Zabuza's fighting style inside out. Then, when they have to face each other, Naruto uses this knowledge to his advantage and defeats Zabuza in a very strategic battle.
In some fanfictions, Naruto wins the war through a prophecy. It was foretold that he would be the one to end the war, and so he is given special powers or artifacts that help him achieve victory. These powers could be something like the ability to control time briefly during battles or to summon ancient and extremely powerful creatures that tip the scales in his favor.
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.
In some fanfictions, Naruto defeats Iwa when he is on a mission to protect something important. Let's say Iwa is after a powerful artifact, and Naruto is tasked with safeguarding it. He uses his skills, along with the help of his friends, to fend off Iwa's attacks. During the battle, Naruto discovers a unique way to counter Iwa's jutsu by combining his own jutsu in an unexpected way. This gives him the upper hand and he manages to defeat Iwa. It's a classic underdog - turned - hero scenario that many fans like.
A common plot is Naruto using his friendship bonds to gain an edge. For example, in many fanfics, his bond with Sasuke becomes a key factor. Sasuke may return to Konoha and fight alongside Naruto against the Akatsuki. Another popular plot is Naruto unlocking some new, super - powerful form. Maybe a combination of all his different power - ups throughout the series that makes him nearly invincible against the Akatsuki.
One interesting way is when Naruto absorbs chakra through his shadow clones. In some fanfictions, the clones can be used not just to gather information or attack, but also to absorb the chakra of the opponents they interact with. Then, they transfer this absorbed chakra back to Naruto, making him more powerful.
Another plot twist might be that Pain has a hidden motive for attacking Konoha that is completely different from what was originally thought. And Naruto, in the process of defeating him, uncovers this truth. For example, Pain could be under the control of a more powerful enemy who wants to test Konoha's defenses through Pain's attack, and Naruto has to deal with this new revelation as well as defeat Pain.
