There could be a story where Catwoman discovers a hidden treasure in Gotham that has the power to heal the city. But she has to race against some non - villainous rivals to get to it first. Along the way, she has to use her wits and her acrobatic skills. This kind of story would be exciting and suitable for all ages.
One idea could be that Batman and Catwoman have a daughter who discovers her parents' secret identities. She could struggle with the duality of their world and try to find her own place in it. Maybe she has her own unique set of skills that combine elements of both Batman and Catwoman.
One idea could be Harry starting a magical gardening project at Hogwarts. He could be growing all sorts of magical plants and using them for potion - making and to beautify the school grounds. It would be a fun and positive story.
One idea could be a story where Tony Stark mentors a young genius. He could pass on his knowledge and wisdom about science and technology, while also teaching the youngster about responsibility. It would be a heartwarming story of growth and friendship.
One great idea could be stories that explore the further adventures of the characters after the end of the series. For example, how Harry, Hermione, and Ron continue to protect the wizarding world from new threats. It could also involve the next generation learning magic at Hogwarts and facing their own challenges in a way that stays true to the original values of the series.
Another family - friendly idea is Mega Man teaching other robots how to use their abilities for good. This could involve some fun training sequences and heartwarming moments of friendship and cooperation.
A fanfiction where Sarada has trouble with a new ninjutsu technique and Sasuke helps her master it. Along the way, they have heart - to - heart conversations about what it means to be an Uchiha and the responsibilities that come with it. This would show their relationship in a positive light and also focus on Sarada's growth.
One idea could be fanfiction about the Powerpuff Girls going on a new adventure in a different city, like saving a famous landmark from a new villain. Another could be them having to deal with a magical creature that has escaped from a hidden realm.
A family - friendly 'Fireboy' story could be about Fireboy helping his family prepare for a big festival in their village. He uses his fire powers to light up the lanterns and create beautiful fire - based decorations.
One idea is for families in different climates to swap. For example, a family from a cold, snowy area could swap with a family in a warm, sunny place. They can enjoy new outdoor activities like skiing in the cold area or beach volleyball in the warm area.
How about a fanfic where the Vault Hunters decide to start a school in Pandora to teach the locals how to defend themselves? It could be full of humorous moments as the tough - as - nails Hunters try to be teachers. Also, a story about a little creature from the Borderlands that befriends a human and they go on a journey to find a magical artifact that can heal the land.
