Well, a great plot for a Naruto x Konohamaru fanfic could involve Konohamaru getting into trouble and Naruto having to rescue him. This could lead to Konohamaru feeling a bit ashamed at first but then being inspired to train harder. Also, they could discover a hidden part of the village together that holds a secret about their ninja heritage. And they might have to face off against an old enemy who has returned with a new vengeance.
One idea could be a story where Konohamaru is kidnapped and Naruto has to use all his skills to rescue him. It could show Naruto's growth as a protector.
One idea could be a crossover where Naruto's world and the world of X - 23 from the X - Men collide. Maybe X - 23 is on a mission and accidentally ends up in the Hidden Leaf Village. She has to learn to adapt to this new place with its different culture and ninja ways. Naruto could be intrigued by her and her abilities, and they could team up to face a common enemy.
Perhaps Neo could teach Naruto about the concept of the digital world, which Naruto then uses to create a new form of jutsu. Meanwhile, Naruto could show Neo the power of friendship and teamwork in the ninja way, changing Neo's perspective on fighting.
One idea could be that Inari, inspired by Naruto's determination, decides to train hard and develop his own unique ninja skills. He could then join Naruto on a small mission in the Land of Waves and prove his worth. Another plot could be a time - travel plot where Naruto is sent back in time to when Inari was a child and he has to protect Inari and his mother from Gato's men in a different way, changing the course of history in the Land of Waves.
One idea could be that Naruto and Erza are brought together by a powerful magic spell that transports Naruto to the Fairy Tail world. They initially misunderstand each other due to their different backgrounds and abilities. But as they face common enemies, they start to learn from one another. Naruto could teach Erza about his ninja way of never giving up, and Erza could show Naruto the power of magic and the importance of friendship within the guild.
A plot where Naruto and Boruto have to team up to fight a new, powerful enemy that neither could defeat alone. This would allow for some great father - son bonding moments and also show how their skills complement each other. For example, Naruto's brute strength combined with Boruto's unique ninja techniques. It could also explore how Naruto imparts his wisdom about the ninja way to Boruto during the battle.
Maybe they meet in a parallel dimension where their respective kingdoms are at war. At first, they are enemies, but as they get to know each other, they realize that there is a greater evil at play. They then team up, with Naruto's ninjutsu and Corrin's dragon powers making them a formidable duo. They fight side by side, learning from each other's strengths and weaknesses.
Maybe in a post - war scenario, Shizune is involved in some medical research and Naruto, having some lingering health issues from the battles, becomes her patient. As she takes care of him, she discovers new sides of Naruto. They start to have long conversations about life after war, and how to build a better future for the village. This shared purpose and the time they spend together lead to a romantic relationship in the fanfic.
Another idea is that in a strange twist of fate, the characters from Naruto have to participate in a Yugioh tournament. Naruto, Sasuke, Sakura etc. would have to learn the rules of the game quickly. Naruto's determination and never - give - up attitude would help him in the tournament, while Sasuke's strategic mind could make him a tough competitor.
One idea could be that Gabriel, with her angelic powers, somehow gets transported to the Naruto universe. She could meet Naruto and be intrigued by his never - give - up attitude. Maybe she decides to help him in his quest to become Hokage, using her unique abilities like healing or protection magic. Another plot could involve a common enemy that both Naruto and Gabriel have to face together, which forces them to combine their different fighting styles.
