In this fanfiction, Ladybug could be ill and in bed. Chat Noir, being the caring partner he is, tries to take care of her. He brings her soup (even though he's not very good at cooking) and tries to cheer her up. Ladybug, on the other hand, is a bit frustrated at being sick but is also touched by Chat Noir's efforts. They end up having a deep conversation about their feelings for each other, but still keep it within the boundaries of their superhero partnership.
Perhaps in this fanfiction, Ladybug is injured and has to stay in bed. Her friends, like Alya, come to visit. Alya brings some of her favorite snacks and they talk about the latest fashion trends. Meanwhile, Chat Noir might be outside the window, leaving little gifts for her to find when she wakes up. It's a chance to show the different relationships in Ladybug's life.
In some fanfictions, Marinette might fight against an alternate version of herself. This could be a version that has been corrupted or turned evil. It would be a really intense battle as she has to face someone with the same skills and knowledge as her. She'd have to dig deep and find the strength within herself to overcome this internal conflict.
One idea could be Ladybug and Chat Noir having a heart - to - heart conversation in bed after a particularly tough battle. They could share their fears and insecurities that they usually hide behind their superhero personas.
One possible scenario could be that Hawkmoth finally achieves his ultimate goal which leads to the death of Ladybug. Maybe he gets hold of both the Ladybug and Cat Miraculouses and uses their combined power in a way that causes a catastrophic event resulting in her death.
One popular storyline could be Marinette having a dream about her future with Adrien while in her bed. In the fanfiction, she might see them getting married and living happily ever after. Another could be Chat Noir secretly visiting Ladybug while she's resting in bed and leaving her a small gift as a token of his affection without her knowing it was him right away.
A truth scenario could be that Ladybug has to tell Chat Noir the one thing she dislikes most about being a superhero. This could lead to a deep conversation about the sacrifices they both make and how they deal with the stress of protecting Paris. It would also show a more vulnerable side of Ladybug, which is not often seen.
Another theme is the power dynamics within the superhero world. How Ladybug's leadership as the main superhero affects the others, and how Chat Noir supports her. Fanfictions can explore different scenarios where they have to make difficult decisions regarding their powers and responsibilities, such as when they face a villain who is stronger than they expected and they have to figure out new strategies using their powers.
Well, one interesting plot could be about Ladybug and Chat Noir having to face a villain who can manipulate time. This would put their skills and relationship to the test as they try to outwit the baddie and protect Paris. Another plot might involve a new Miraculous holder emerging and how they interact with Ladybug and Chat Noir, whether it's as an ally or a potential adversary.
One interesting plot could be an alternate universe where Ladybug and Chat Noir have different powers. Maybe Ladybug has the power of ice instead of her usual creation abilities. Another plot could be a time - travel story where they go back to the very beginning of Hawk Moth's reign and try to stop him before he becomes too powerful. And there could also be a story where Ladybug and Chat Noir have to team up with their civilian selves to solve a mystery.
There could be a fanfiction where Ladybug and Chat Noir swap their Miraculous permanently. Chat Noir, now as Ladybug, has to learn how to be more strategic and responsible, while Ladybug, as Chat Noir, discovers the freedom and playfulness that comes with his role. They face challenges in adapting to their new identities and powers, and it also affects their relationship with each other and their friends.
