It could be a new villain created specifically for the fanfiction. Maybe someone who has a vendetta against Chloe and targets her because she has the Miraculous.
One possible plot could be Chloe's journey of self - discovery with the Miraculous. Maybe she starts off using it for the wrong reasons, like for personal gain or to show off, but then realizes the true power is in helping others.
One common theme is redemption. Since Chloe is often portrayed as a bit of a bully in the original, many fanfictions focus on her becoming a better person. Another theme is friendship. How she interacts with the other Miraculous holders and forms new relationships.
I think Sabrina could be paired well with Chloe in a fanfic. Sabrina is Chloe's sidekick in the show, but in a fanfic, their relationship could evolve. For example, Sabrina could start to stand up to Chloe and this could lead to a whole new dynamic between them. Also, Luka could be paired with Chloe. Luka's calm nature could contrast with Chloe's brashness and it could make for an interesting story of how they influence each other.
One possible scenario in this fanfiction could be that Marinette and Chloe start off as rivals as in the original series. But then, through a series of events, like working together on a school project. They begin to understand each other better. Marinette realizes that Chloe's brash behavior is often a cover - up for her insecurities. And Chloe starts to see Marinette's kindness and determination not as weaknesses but as strengths. This new understanding could lead to a tentative friendship, which would be a great development in the fanfiction.
One idea could be Chloe's redemption arc in a fanfic. Maybe she starts to realize the error of her ways after a particularly harsh event. For example, she could lose her status among her peers and have to start from scratch to earn their respect. Another plot could be Chloe getting a new Miraculous and learning what it really means to be a hero. She might struggle at first with the responsibilities but grow into a great hero over time.
Sure. One popular Chloe Bee Miraculous fanfiction is 'Chloe's Redemption'. It focuses on Chloe's journey to become a better person. Another great one could be 'Chloe and the Miraculous Team' which shows her interactions with the rest of the team in unique ways.
They could be paired up for a hero - training exercise. Since Marinette is Ladybug and Chloe has been Queen Bee in the past. They have to learn to work as a team. This forces them to put aside their differences. They might start to see each other in a new light. For instance, Marinette could learn that Chloe has a lot of knowledge about Parisian high society that could be useful in fighting villains. And Chloe could see Marinette's strategic thinking as Ladybug.
Perhaps Chloe is wrongly judged in some sort of afterlife court and is sent to hell. Once there, she meets other souls who help her realize that there's a conspiracy behind her being sent there. So she starts to fight against the system of hell to prove her innocence.
Perhaps in the fanfiction, Nathalie gets a Miraculous that has a special connection to her past. As she uses it, she starts to remember things from her childhood that are related to the Miraculous. This could lead her to question her loyalty to Hawk Moth and start to work towards a more positive side.
