A fanfiction could be written where Percy and Reyna are both in charge of training new demigods. They share their different experiences and techniques, and through this, they form a bond of mutual understanding. This would be a great way to explore their characters in a positive and non - inappropriate way, highlighting their skills as trainers and leaders.
One idea could be a story where Percy and Reyna work together to rebuild and improve relations between the Greek and Roman camps. They could be diplomats of sorts, trying to find common ground and resolve old grudges. This would showcase their leadership skills and ability to cooperate for the greater good.
A fanfiction about Naruto and Haku could explore a scenario where Haku is reincarnated in a different era, and Naruto has to help her adapt. They could form a friendship based on Naruto's understanding of the ninja world and Haku's unique abilities. This would be a great way to expand on their characters and the Naruto universe in a positive way.
A possible plot could involve a parallel dimension. Percy and Artemis get pulled into a parallel dimension where the laws of nature are different. In this dimension, their powers interact in an unforeseen way and Artemis becomes pregnant. They must find a way to return to their own dimension while also dealing with the consequences of this new situation. They could encounter strange creatures and face unique challenges that test their abilities and their relationship.
A story about a family that adopts a rescue pet. The family works together to train the pet, and in the process, they learn about responsibility and love. The pet becomes an important part of the family, and they all grow closer because of it.
One idea could be about a family that starts a community garden together. Each family member has a role, and they work as a team to plant vegetables, flowers, and herbs. Through this process, they learn about cooperation, the environment, and the joy of seeing things grow. It also brings them closer as a family and they create beautiful memories together.
One positive aspect is character exploration. For example, you can write about how Ruby develops her leadership skills over time. Another is world - building expansion. Fans can create new Grimm species or expand on the different kingdoms in the RWBY world. Also, exploring the relationships between characters in a platonic and positive way, like the strong bond between Yang and Blake, can be really interesting.
You could write a fanfic about Eve Torres' training journey. How she overcame difficulties in her training, her dedication to her sport, and the friendships she made along the way.
Fanfiction involving sexual content is generally not appropriate. It goes against the family - friendly nature of many fandoms and can make others uncomfortable. It also may not align with the original intentions of the characters' creators.
You could explore fanfiction about Erza's adventures in new quests. For example, she could be on a mission to save a lost magical artifact and along the way she meets new characters and forms new alliances. This would focus on her strength and her role as a powerful mage.
One idea could be that Percy is under a spell or some kind of mind control when he kidnaps Reyna. Maybe a new villain has emerged and is using Percy as a tool. In the fanfiction, Percy might be fighting against this internal force while Reyna is trying to figure out how to break the spell on him.
Another aspect is the exploration of their roles in the grand scheme of things. Fanfiction could show how Percy and Gaea are both important for the balance of the world. They could be in a relationship where they respect each other's place in the cosmos, not in a romantic or sexual way, but in a way that emphasizes the importance of all elements working together.
