Maybe Naruto gives advice to a group of ninjas on how to handle a difficult mission. He could talk about the importance of teamwork, like how he relied on his friends in Team 7. He might say things like 'Always trust your teammates, know their strengths and weaknesses, and communicate clearly during the mission.'
A fanfic plot could involve Naruto giving advice to a ninja from another village. Naruto, being a symbol of peace, would tell the foreign ninja about the power of forgiveness and understanding. He could share how he forgave those who once wronged him in Konoha and how that led to a stronger and more united village. This would show the foreign ninja a different way of thinking and help them deal with internal conflicts in their own village.
One possible plot could be Naruto learning new and unique jutsus from Kurenai. Since Kurenai is skilled in genjutsu, she could train Naruto in the ways of genjutsu, which he is not very good at initially. This would open up new storylines as Naruto struggles to master this different form of combat and uses his own creativity and determination to adapt genjutsu to his fighting style.
Another plot could be that Zabuza's sword ends up in the hands of an enemy of Konoha. Konoha sends a team of ninjas, including some of the younger generation like Naruto and his friends, to retrieve it. Along the way, they learn about Zabuza's legacy and the true strength of the sword. They have to battle the enemy who has already started to unlock some of the sword's powers, but in the end, they manage to get it back and decide what to do with such a dangerous weapon.
One possible plot could be Naruto being transported to the Claymore world. He might initially struggle to understand the unique rules and the existence of Yoma. But with his ninja skills and never - give - up attitude, he could start training Claymore warriors in new combat techniques, like his shadow clone jutsu. This would change the power dynamics in the Claymore world as they now have a new way to fight Yoma and Awakened Beings.
One possible plot could be that Naruto finds himself in the world of Kenichi and decides to train at the Ryozanpaku dojo. He could bring his unique ninja skills and chakra techniques, which would amaze the masters there. Maybe he'd get into friendly sparring matches with the disciples, teaching them some of his ninja tricks in return for learning their martial arts. 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.
A possible interesting plot could be Naruto discovers a hidden ninja village where parkour is the key to unlocking ancient secrets. He has to master new parkour skills to traverse the village's dangerous terrains filled with traps and challenges, all while facing off against a rival ninja group who also wants the secrets.
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.
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. For example, he could use his shadow clone jutsu to chop ingredients really fast. His unique style of cooking, influenced by his ninja life, would surprise the judges and the other contestants.
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. They end up forming an unlikely alliance to face a common enemy that is threatening both the ninja world and the mummy's resting place.
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.
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.
