Well, perhaps the fanfiction might be trying to force relationships that don't make sense in the context of the Miraculous Ladybug world. The show has its own set of relationship dynamics and character arcs, and some fanfictions might deviate too much from that. Also, it could be that the fanfiction is too dark or violent compared to the relatively light - hearted tone of the original series.
It could be because the fanfiction might be misinterpreting the lore or the powers of the Miraculous. The world of Miraculous Ladybug has a complex system of powers, magic, and rules. If a fanfiction doesn't respect these and creates a jumbled - up version, it might not be a good idea. For instance, if it gives a Miraculous power that completely contradicts what has been established in the show, it can be off - putting for fans who are well - versed in the series.
It could be about a character in the Miraculous Ladybug universe who feels misunderstood. Maybe they have a secret identity or a hidden power that others are unaware of. For example, a new character who is actually a powerful superhero in disguise but is treated as an ordinary person by Ladybug and Chat Noir.
Perhaps Plagg cries because he feels guilty. He might have made a mistake, like accidentally revealing something to the wrong person about the Miraculous powers or secrets. This guilt could be overwhelming for him. Also, it could be that he's sad about the state of the world in the Miraculous Ladybug universe. There are so many akumas and problems, and he might feel powerless to really change things in a big way.
One thing you might not know is that some fanfiction explores alternate universes and unexpected pairings that add a whole new dimension to the Miraculous Ladybug world. Also, there are fanfics that delve deep into the characters' backstories and motivations, revealing aspects not shown in the original.
First, make sure to really understand the characters. Read up on their backstories, personalities, and how they interact with others in the original series. This way, you won't create a version of them that is out of character. Second, stay true to the overall theme of the show, which is about friendship, love, and fighting against evil in a fun and positive way.
In a Miraculous Ladybug sleepover fanfiction, the characters might have a lot of fun. They could play games like truth or dare, which could lead to some interesting revelations. For example, Marinette might accidentally let slip some of her feelings for Adrien.
In the fanfic, it could be related to an emotional turmoil as well. Adrien has a lot of personal issues and secrets. If something really bad happened, like he found out some truth about his family that shocked him to the core, it might have made him distracted during a fight or a dangerous situation. This distraction could have led to him being in the wrong place at the wrong time and getting caught under the rubble when something like an explosion or building collapse occurred.
One possible reason could be that he got injured during a fight with an akumatized villain. In the Miraculous Ladybug universe, battles can be quite intense and Adrien, as Chat Noir, often puts himself in harm's way to protect Paris. Another reason might be some sort of illness that was magically induced, perhaps by a new villain with a different kind of power that targets the heroes in a non - traditional way. It could also be due to overexertion from using his Cat Miraculous too much without proper rest, which could lead to his body breaking down and him ending up in the hospital.
It could be related to his emotional state. Adrien has a lot of pressure on him, both as a model and as Chat Noir. The stress could have taken a toll on his health, causing him to collapse and be hospitalized. In the fanfiction, this could be the starting point for his friends, like Nino and Alya, to realize how much Adrien has been hiding and struggling, and they could come together to support him in a new way.
It could also be that Hawk Moth has a new scheme. He might have manipulated the situation to make it look like Marinette is a threat. He could have planted false evidence or used an Akuma to make someone accuse her, all in an attempt to get to Ladybug.
One possible plot for a Miraculous Ladybug beach fanfiction is that Hawkmoth sends an akuma to the beach during a big surfing competition. Chat Noir is there to compete, and Ladybug has to show up and they end up having to fight the akuma while also trying to protect the civilians at the beach. They could also have some cute beach - themed banter in between the fight scenes.
