In a Marinette - missing fanfiction, it could be that she has amnesia and has wandered off. She might not remember who she is or where she lives. The other characters would notice her absence quickly. Tikki would be especially worried and try to guide Chat Noir to find Marinette. The city of Paris would seem a little less bright without her, and the story could focus on how everyone comes together to find her and restore her memory.
She could have been kidnapped by a new villain who wants to use her skills as a fashion designer for some evil purpose. Since Marinette is so talented, this villain might think she can create special costumes or items for their evil plans.
One possible scenario could be that Marinette gets injured during a fight as Ladybug and is rushed to the hospital. In the fanfiction, her friends might come to visit her, and there could be some sweet moments between her and Adrien as he's worried about her. Maybe she has to keep her identity a secret even while in the hospital, which adds an extra layer of tension.
There's also 'The Luka - Marinette Connection'. In this fanfiction, the connection between Luka and Marinette is explored on a deeper level. It starts with Luka noticing Marinette's little quirks and how she tries to hide her feelings. As the story progresses, they start to open up to each other more. The author creates a really engaging story by adding in some mystery elements related to the Miraculous and how it might affect their relationship.
One great fanfiction could be about Marinette getting the Peacock Miraculous in a unique situation. For example, in a world where all the Miraculouses are scrambled among the characters, Marinette discovers the Peacock Miraculous while on a solo adventure. She has to figure out how to use its powers, which are different from the Ladybug Miraculous she's used to. This could lead to some really interesting character development as she tries to master a new set of abilities.
One possible fanfiction could be about Marinette transforming into a mouse - themed Miraculous holder. Maybe she discovers a new mouse - themed Miraculous in a hidden part of Paris. This could lead to her having new powers like super - speed and the ability to fit into small spaces. She could use these powers to outwit Hawk Moth's akumas in a really unique way, and her relationship with Adrien might also take an interesting turn as she tries to keep her new identity a secret from him.
In Miraculous Ladybug fanfiction, Marinette in a bikini could be part of a beach - themed story. Maybe she's on vacation with her friends. It could be a fun and light - hearted scenario where she shows off her confidence and style while enjoying the sun and sand.
I really like 'The Hidden Bond'. In this fanfiction, Marinette discovers a new side to Cat Noir that she hadn't seen before. It's full of cute moments and some really well - written dialogue. It also has an interesting plot that keeps you hooked from start to finish.
There are many fanfictions where Marinette sings. In some, her singing might be related to her expressing her feelings for Adrien. For example, she could sing a song she wrote herself about her secret love for him. It adds a creative and emotional aspect to the story.
One possible fanfiction could be about Marinette using her flexibility in a new way to design fashion. For example, she might create a line of clothing that is both stylish and allows for maximum movement, inspired by her own experiences as Ladybug. She could hold a fashion show where models are shown doing acrobatic stunts while wearing her designs, highlighting the flexibility aspect of the clothes.
