One possible fanfiction could involve Chat Noir being akumatized after a major argument with Ladybug. Maybe he feels constantly overshadowed or unappreciated. The akuma could enhance his negative feelings, making him more aggressive and less in control. His powers might become distorted, and he could start causing chaos in Paris. Ladybug would then have to find a way to reach out to the real Chat Noir inside the akumatized form and purify the akuma.
One great Miraculous Ladybug Chat Noir x OC fanfiction is 'The New Hero in Paris'. It has an interesting OC who has unique powers and a great dynamic with Chat Noir. The story is full of action and mystery.
She would also be very determined to bring him back to the good side. Ladybug might search for a way to break whatever spell or influence has made Chat Noir evil. She could look for a special power - perhaps from another Miraculous or a magical item - that can reverse the change. And in the meantime, she has to be careful not to get hurt by Chat Noir while still trying to protect Paris.
One popular 'Miraculous Ladybug x Chat Noir fanfic' story could be those where they reveal their identities early on and have to deal with the new dynamic. Another might be ones that explore their relationship in a different time period, like in the future. There are also fics that focus on their teamwork in really difficult akuma battles.
One interesting idea could be exploring different alternate universes where Ladybug and Chat Noir have different relationships. For example, in some fanfictions, they might have to deal with their identities being revealed in a more complex and emotional way compared to the original show. Another idea is the exploration of their powers in new and unique situations that the show hasn't covered yet.
First, create a well - developed OC. Give them a unique personality, backstory, and powers if applicable. For example, an OC could be a shy artist who discovers a new Miraculous. Then, focus on the relationship with Chat Noir. Build it slowly, like having them start as friends and gradually develop deeper feelings. Also, keep the tone and style similar to the original show. Use vivid descriptions of Paris and the action scenes.
How about a fanfiction where there's a new villain in Paris who has the power to nullify the Miraculous? Ladybug and Chat Noir would have to find a way to regain their powers or find new ways to fight this powerful enemy without relying on their usual abilities.
You can start by looking on fanfic websites like Archive of Our Own. They have a large collection of 'Miraculous Ladybug x Chat Noir fanfic' and you can filter by popularity, rating, and genre. Another option is to check out fan communities on social media platforms. People often share their favorite fics there.
Another plot could involve Chat Noir being akumatized by an akuma that was specifically designed to target him. Hawkmoth could have studied Chat Noir's behavior and weaknesses. Once akumatized, Chat Noir could start to turn Paris against Ladybug. He could spread false rumors or use his charm in a negative way. Ladybug would then need to prove her innocence and save Chat Noir from the akuma's control. This would require her to dig deep into their relationship and find a way to reach the real Chat Noir.
Ladybug and Chat Noir themselves are very popular. Writers love exploring their relationship, both as superheroes and the possible romantic feelings between them.
