One interesting plot could be that Naruto fails to save Sasuke in their final battle and realizes he made a crucial mistake. So, he somehow gets a chance to go back in time. He then uses his knowledge of the future to train harder, understand his enemies better, and tries to prevent Sasuke from leaving the village in the first place. He focuses on building stronger bonds with Sasuke from the start and also works on improving his own jutsu in new ways that he didn't think of before.
Maybe Naruto dies during the Pain invasion because he made some hasty decisions. But then he's given a second chance. This time, he decides to take a different approach. Instead of charging in alone, he works with the other ninja in the village more closely. He spends time learning more about Pain's motives before engaging in battle. He also tries to master new forms of Sage Mode that he didn't have time for before, which could potentially change the outcome of the battle and save the village without as much destruction.
A possible plot is that Naruto messes up his first attempt at becoming Hokage. He realizes that he focused too much on popularity and not enough on the real issues the village faced.

He also focuses on improving the ninja academy, making sure that future generations are better trained. He forms alliances with other villages earlier in his tenure as a way to strengthen Konoha and show that he's a different kind of leader.
If a character like Sasuke, who has made many mistakes, wants to be redeemed, he could start by apologizing to those he has hurt. For example, he could go to Naruto and admit that he was wrong in his quest for revenge. Then he could use his skills to help protect the village instead of trying to destroy it. He could also mentor the younger ninja, teaching them about the importance of not being consumed by hatred.
Well, it could be that Naruto's friend from another village, who has been like a brother to him, has to go back to his own village for good. Naruto, being the emotional and kind - hearted person he is, decides to sing 'See You Again' at the border as a way to say goodbye. This song could also symbolize the hope that their friendship will endure despite the distance. And during the singing, there could be some emotional exchanges between Naruto and his friend, like promises to visit each other in the future.

One possible plot could be that Naruto somehow gets transported to the Pokemon world. There, he meets a group of Pokegirls. They initially misunderstand him as a threat but later realize he can be a great ally. Together, they embark on a journey to stop an evil organization that is trying to capture all the Pokegirls for their own malicious purposes. Naruto uses his ninja skills like shadow clone jutsu to help in battles and outwit the bad guys.
In a 'naruto impmon fanfic', the plot could revolve around Impmon being a spirit guide of sorts to Naruto. Impmon has a different way of looking at things due to his digital world origin. He could guide Naruto through some difficult moral decisions. For instance, when Naruto is faced with the choice of using a powerful but dangerous jutsu that could harm innocent people, Impmon could share his experiences from the digital world where there were similar choices about using powerful digital powers that had consequences. This could lead to Naruto finding a new and better way to handle the situation.
One possible plot could be that Naruto is on a mission in an ancient tomb and accidentally awakens a mummy. The mummy, instead of being hostile, has some unique chakra that Naruto is curious about.

One interesting plot could be Naruto entering a cooking competition in the Hidden Leaf Village. He might use his ninja skills, like speed and precision, to prepare amazing dishes.

One possible plot could be Naruto being summoned into the DxD world by some sort of magic accident. He might initially be confused but quickly adapt his ninja skills to the new environment. He could team up with some of the DxD characters to face a common enemy, like a powerful fallen angel or a rogue devil. His Rasengan and shadow clone techniques would be quite unique in this world.
Well, perhaps Kirby is seen as a sort of spirit animal in the Naruto fanfic. The ninjas believe he has some sort of special chakra or power. Kirby teams up with Naruto, and together they go on adventures. Kirby's ability to float and move quickly could be useful in battles and in traversing the various terrains in the Naruto world. He could also use his inhaling power to clear away debris or obstacles during rescue missions.
One possible plot could be that Naruto finds himself in the world of Kenichi and decides to train at the Ryozanpaku dojo.

This would create a lot of comical and action - packed moments as Naruto's high - energy ninja style clashes with the more traditional martial arts of the Kenichi universe.
