An appropriate fanfic idea could be centered around Hinata's own growth as a ninja. You could write about her mastering new jutsu, her relationships with her teammates in a more positive and respectful way, and how she becomes a stronger and more confident character. Also, a fanfic about the backstories of the various ninja clans in the Naruto world would be really interesting. It could explore their histories, traditions, and how they interact with one another in different situations.
Another idea could be a story where Naruto meets Grayfia in a different dimension. At first, they are at odds because of their different backgrounds, but then they learn from each other and become friends. They could exchange knowledge about their respective worlds, like Naruto teaching Grayfia about chakra and Grayfia showing Naruto some magic spells.
A Wendy fanfic could also focus on her musical journey. Maybe she joins a band and they work together to write a song that will save their small town from losing its cultural heritage. They have to overcome differences in musical styles and personal conflicts to create the perfect melody.
The idea of 'birth fetish' in fanfiction is inappropriate and often goes against ethical and moral standards. Some great alternative Naruto - related fanfiction themes could be exploring different character backstories, like how Kakashi became so skilled at a young age. Another could be focusing on the relationships between the characters in non - inappropriate ways, such as the friendship between Naruto and Shikamaru. And there could also be fanfictions about new adventures that the Naruto characters could go on, like exploring a new and mysterious land outside of the Hidden Villages.
A celestia fanfic could be centered around her relationship with her fellow ponies in a non - romantic, more of a mentorship way. For example, how she helps a young pony discover their own unique magical abilities.
One idea could be a story about Blake's adventures in a new part of her world, where she discovers ancient secrets. For example, she could stumble upon an old ruin that holds the key to a long - forgotten power. This would involve her using her skills and wits to unlock the mysteries within.
A fanfiction where they discover a hidden part of the real world that has a connection to the Other World. Maybe an old, abandoned house in their neighborhood that holds secrets and ancient magic. They explore it together, trying to figure out how it relates to the events in the Other World they already know.
One alternative could be a fanfic where Lily Potter appears as a spirit guide to Harry. She gives him advice and helps him make difficult decisions, like when he's facing tough moral choices during the fight against Voldemort. This would show their strong bond and how her influence can still be felt even though she's not physically present.
Another type of good Naruto fanfic is the one that delves into the post - war era. It could be about how the different ninja villages collaborate to rebuild and how the new generation of ninjas are trained in a more peaceful yet still challenging environment.
One great alternative could be a fanfic about Bulma's scientific achievements. She's known for her intelligence and her inventions in the Dragon Ball series. You could write about her creating a new amazing device that helps the Z - Fighters in a battle. Another idea is a fanfic focusing on her relationship with Vegeta. How they interact, support each other, and grow as a couple. It could show their domestic life or how they handle challenges together.
A positive fanfic could be set during a time of crisis in the Hidden Leaf Village. Naruto and Tsunade have to work together to come up with a strategy to protect the village. Along the way, they learn more about each other's strengths and weaknesses, and their bond as comrades in the village grows stronger as they face the threat together.
