Well, in a toddler Naruto fanfic, you could have a plot where Naruto discovers a hidden power within himself at a very young age. For example, he might find out he can communicate with plants, which is something no one else in the village can do. This could lead to him making new friends among the plant - like creatures in the forest. Also, a story about toddler Naruto's first encounter with a simple ninja tool, like a shuriken, and how he plays with it in an innocent yet dangerous way would be interesting.
A toddler Naruto fanfic could center around Naruto's relationship with the other toddlers in the village. Maybe there's a toddler who is always getting into trouble, and Naruto tries to be a good influence on him. Or it could be about Naruto's first day at a toddler - only ninja training session, where he's excited but also a bit scared. He could make friends with a shy toddler during the training, and together they learn the basics of being a ninja, like how to hide and seek in a ninja - like way.
One plot idea could be Minato somehow being brought back to life for a short time and getting to spend precious moments with toddler Naruto. He could teach Naruto some basic ninja skills that Naruto would later forget but unconsciously use in his training. Another idea is a story where toddler Naruto is in danger and Minato's spirit appears to protect him, guiding Naruto to use his own latent powers. And perhaps a story where Minato's memories are transferred to toddler Naruto, giving him flashes of his father's life.
One idea could be a time - travel fanfic where Naruto or Sasuke go back in time and try to change certain events. This would allow for a lot of creative storytelling as they interact with their younger selves and try to prevent future tragedies.
One idea could be to create an alternate universe where Naruto has a different elemental affinity from the start. For example, instead of wind, he has lightning. Another could be a fanfic focused on the relationships between the characters outside of the main plot, like how Sakura and Ino rekindle their friendship in a more in - depth way. Or you could write about Naruto's training journey with a different mentor, say Jiraiya's long - lost brother who has a completely different teaching style.
One idea could be a fanfic where Naruto travels to a different dimension where the Akatsuki are the heroes. Another could be a story about Naruto's kids growing up in a world where there's a new threat that they have to face without their parents' immediate help. And a third idea is a fanfic where Naruto discovers a hidden bloodline within himself that gives him unique powers.
In 'naruto wings fanfic', often there are ideas related to the origin of the wings. Are they a result of some new form of chakra? Or perhaps they are a gift from a mysterious entity. The fanfic might also delve into how the wings affect the character's relationships. For instance, do their friends become jealous of their new powers, or do they attract new allies who are interested in the wings' capabilities?
Another interesting aspect could be femto Naruto's impact on the ninja world. Since he would be different in this form, he might introduce new jutsu or ways of thinking. He could inspire younger ninjas to think outside the box and break traditional boundaries in their training and combat.
Another idea is a crossover where the world of Naruto is invaded by Honkai. The shinobi have to learn about Honkai technology and powers quickly to defend their villages. Sakura might study Honkai biology to find a way to counter the threat, while Sasuke could be intrigued by the dark powers of the Herrschers and struggle with the temptation to use them for his own goals.
One interesting idea could be how the laws of the Naruto universe are explored. For example, how the ninja code functions as a form of law among the ninja clans. It might also look at how different villages have their own rules regarding things like chakra use and shinobi behavior.
One idea could be Naruto becoming a mentor to a new generation of ninja. He could pass on his unique skills and the importance of friendship and hard work.
A fanfic could also focus on a character from Kuroinu coming to the Naruto world. This character could be initially confused but then starts to understand the concept of ninja and tries to adapt. Maybe they form an unlikely alliance with Naruto to achieve a common goal, like saving both their worlds from a greater threat.
