Perhaps Wilson is a character in a particular series or a book. He might be the protagonist who has a special connection with the stories he reads, like using the stories to solve problems or gain wisdom in his own life.
Susan Wilson could be many things. She might be a local hero in her community who has done great things like starting a charity or helping the environment. Or she could be an entrepreneur who has had a unique journey in building her business. Without more context from the story, it's hard to say precisely who she is.
Since I don't know the specific story, it's difficult to say exactly who Mrs Wilson is. She could be an ordinary woman with an extraordinary story, or she might be someone well - known in a particular community or field.
As I don't know the story, it's hard to say exactly who Angel B Wilson is. It could be an ordinary person with an extraordinary story, or it could be a fictional character created for a particular narrative.
Without more information, it's hard to say exactly who Bill Wilson is. He could be an ordinary person sharing his life experiences, or he could be someone known in a specific community or field.
One idea could be that his dad initially reacts with shock and disbelief. He might start to question how he didn't notice all the signs before. Then he could try to use Adrien's identity as Chat Noir to further his own business or social standing in some way, creating a lot of internal conflict for Adrien.
Maybe a mysterious new character in the fanfiction. This character could be from Adrien's family's past, someone with a vendetta against his family, and decides to start by getting Adrien arrested to disrupt the family. For example, if Adrien's family wronged this character's family long ago, they see Adrien as a target to take revenge on the whole family.
It could be Ladybug. If Adrien turns villain, Ladybug would be the natural antagonist as she represents the good side. Their relationship would be completely flipped from what it was before. She would have to try to stop him from causing more harm, all while probably still having some feelings for the old Adrien.
These fanfictions usually show Adrien with a lot of flaws. He might be painted as being manipulative, using his charm to get what he wants without considering the feelings of those around him. Sometimes, he is shown as being irresponsible, not taking his role as a superhero seriously enough. They really dig into the idea that he is not as perfect as he seems in the original series. They may also show him as being overly jealous, which can cause problems in his relationships. For instance, if he is jealous of another character getting close to Ladybug, he might act out in a negative way.
Nathalie might be a character in these fanfictions too. Given her role in Adrien's life in the original series, she could be involved in the events leading up to his akumatization. Maybe she accidentally triggers his negative emotions. And then there's Gabriel, Adrien's father. His actions or lack of actions towards Adrien could be a major factor in Adrien getting akumatized. So, he could be a key character in the fanfiction, either as someone who realizes his mistake and tries to help or as someone who makes the situation worse.
