Another aspect to consider is that it could be a way to develop his character further. Through his injuries and the pain he endures, we can see his growth, his vulnerability, and how he copes with difficult situations. This can add depth to his character in the fanfic.
A common plot device is the miscommunication that leads to Chat Noir getting hurt. For example, if he misunderstands Ladybug's intentions and rushes into a dangerous situation.
Maybe it's because he's such an interesting character. Writers are more likely to write good fanfics about him, and so there are more good ones for him to see.
It could mean that Chat Noir, perhaps from a particular fictional universe like Miraculous Ladybug, has a knack for coming across high - quality fan - created fiction. Maybe he's just lucky in finding well - written stories by fans that are engaging and true to the spirit of the source material.
Chat Noir is often extremely helpful in fanfics. He uses his superpowers like cataclysm to protect the city and the people he cares about. For example, in many fanfics, he might save a civilian from a falling building by using his agility and acrobatic skills. His helpful nature also extends to his relationships, as he is always there to support Ladybug, whether it's in battles or in dealing with personal issues.
One common plotline is that Ladybug has to take on a more challenging role in protecting Paris alone while Chat Noir is injured. She might struggle with the extra pressure and worry about her partner. Another could be Chat Noir dealing with his injury and trying to hide it from Ladybug so as not to worry her. For example, he could keep getting into dangerous situations while still hurt, thinking he can handle it.
It often drives the story forward. For instance, when he sees good in a villain, it might lead to a redemption arc for that character, changing the whole dynamic of the conflict in the fanfic.
It can strengthen their relationship. Ladybug may become more protective of Chat Noir, showing a deeper level of care. For instance, she might be more hesitant to let him engage in battles until he's fully recovered.
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 example could be when Chat Noir befriends a character who is initially seen as a troublemaker in the fanfic. He sees past their rough exterior and discovers their love for art, which no one else bothered to notice.
