One common plotline is Ladybug having to take on more responsibility while Chat Noir is injured. She might have to fight akumas alone and also take care of Chat Noir at the same time.
In many fanfictions, Marinette might get injured during a battle with an akumatized villain. For example, she could be caught off - guard while trying to protect someone. Her injury could then lead to some really emotional moments, like Adrien finding her and being extremely worried. This could also be a turning point in their relationship, making Adrien realize his true feelings for her.
Well, it could be about the characters from Miraculous Ladybug having a chat while under the influence of catnip in a fan - created story. But without reading it specifically, it's hard to say exactly.
In the Miraculous Ladybug group chat, Ladybug and Chat Noir were casually chatting. Ladybug typed, 'We need to be more vigilant about Hawk Moth's next move.' Chat Noir replied with a cat emoji and 'Sure thing, m'lady. But we could also use some time for fun.' Then Rena Rouge joined in, 'I heard there's a new akuma victim in the park. We should check it out.' And so, they planned their next adventure right in the group chat, ready to save Paris once again.
One possible scenario in this fanfiction could be that Ladybug and Chat Noir are injured during a battle with a particularly powerful akuma. Maybe they underestimated the akuma's new abilities. For example, the akuma could have a power that disrupts their Miraculous powers temporarily, making them more vulnerable to attacks. Their injuries might lead to a moment of self - discovery as they realize their limits and have to rely on each other in a different way, like Chat Noir having to protect Ladybug while she tries to figure out a new strategy to defeat the akuma without relying fully on her usual powers.
In many such fanfictions, Chat Noir might get hurt during a fight with a powerful akuma. Maybe he's outnumbered or faces a new and dangerous power. Writers often use this to create drama and show Ladybug's concern for him.
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.
Common themes include the impact on relationships. If Chat Noir is injured, his relationship with Ladybug might change. She could become more protective or he could feel like he's a burden. Additionally, the theme of facing fears is often present. The injured character has to face their fear of not being able to fight again, or of being permanently damaged, which adds depth to the fanfiction.
In a fanfic, Adrien might collapse injured because of some sort of curse or negative magic. For example, a new villain discovers a way to target the Miraculous holders directly. Adrien, being Cat Noir, is affected and his powers start to backfire on him, causing him to collapse. His partner, Ladybug, then has to figure out how to break the curse and save him.
