There might be a 'little naruto fanfiction' where Naruto discovers a hidden jutsu from his parents' past. This jutsu could potentially change the way he approaches battles and his relationships with others in the village. For example, it could be a jutsu that allows him to understand the true feelings of his opponents, leading to some unexpected alliances.
One interesting 'little naruto fanfiction' could be about Naruto having a secret animal friend that only he can communicate with. It adds a new layer to his adventures in the Hidden Leaf Village.
There could be a fanfiction where Naruto's little sister is sent on a special mission. She has to go undercover in an enemy village. Along the way, she makes new friends who are initially suspicious of her but come to respect her as they see her determination and kind heart. She also uncovers a plot that could endanger both her village and the one she's infiltrated.
One interesting 'little naruto time travel fanfiction' could be where Naruto travels back to the time when the Uchiha clan was still intact. He tries to prevent the massacre by befriending Itachi earlier and changing the course of events in Konoha. Another might involve Naruto going back to his own childhood and using his future knowledge to train harder and avoid some of the early embarrassments.
One interesting storyline could be Minato teaching Naruto some of his signature jutsu from a young age. For example, Minato could start showing Naruto how to form the Rasengan at a much earlier stage in his life. This would not only strengthen their bond but also make Naruto a more formidable ninja earlier on.
One interesting concept could be new jutsu created by the characters. For example, they might combine different elemental jutsu in unique ways that we don't see in the original Naruto series. Another concept could be different relationships between the characters. Maybe Naruto has a different kind of friendship with Sasuke, or a new character in the Little Garden fanfiction changes the whole dynamic of their relationship. Also, the fanfiction might explore different settings within the Naruto universe, like a hidden village that has a completely different culture and way of life compared to Konoha.
One interesting aspect could be the unique character interpretations. Fanfiction often takes the existing Naruto characters and puts them in new situations or with different personality traits. It might explore relationships between characters in ways not shown in the original manga or anime.
One idea could be Orochimaru taking an unexpected interest in Naruto's growth not for his power but for his unique way of seeing the ninja world. Maybe Orochimaru starts to secretly guide Naruto in some unorthodox ways of chakra control, which Naruto initially resists but later realizes could be useful.
In this fanfiction, perhaps the plot takes a wild turn. Since Naruto is 'a little crazy', it might involve him making some really unexpected decisions. Like, he could decide to challenge all the Kages at once just for the fun of it, which would completely change the power dynamics in the Naruto universe.
One interesting crossover could be the ponies having to face ninja - like challenges. For example, Rainbow Dash might use her speed in a way similar to how Naruto uses his. Another could be Twilight Sparkle learning some of the chakra - based magic from the Naruto universe. It would be really cool to see how the different magical elements in My Little Pony interact with the ninja techniques.
One idea could be that little Naruto gets lost in the forest and Kakashi has to find him. Along the way, Kakashi discovers Naruto's secret hiding place filled with his dreams and wishes written on little scrolls.
One interesting Little Nightmares 2 fanfiction could be about the backstory of Mono. Maybe it dives deep into his life before he met Six and how he came to be in that strange and terrifying world. It could explore his fears and his hopes in that desolate place.
