Perhaps Adrien has read some fanfiction himself. This might give him insights into how fans perceive the characters and storylines. He could also be using this knowledge to interact with fans in a more engaging way, understanding the different interpretations and scenarios that fans create in their fictional works.
Another thing that could occur is that their relationship dynamic would completely change. Instead of the usual cat - and - mouse game between Adrien and Marinette (where Marinette is shy around Adrien), Adrien could be more open and direct with her. Since he knows her big secret, he might feel a stronger connection to her and try to get closer in a different way than before.
They could also start training together more often. Since Adrien is aware of Marinette's identity, they can practice their superhero skills without the worry of revealing themselves. This would make them a more formidable team. They could learn from each other's strengths and weaknesses, and Ladybug and Chat Noir would be able to defeat akumas more quickly and efficiently.
If Adrien were Hawkmoth in fanfic, it could change the dynamics of the story completely. It might explore his internal conflicts and the impact on his relationships with other characters.
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.
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.
Once upon a time, Marinette and Adrien's big day finally arrived. The city of Paris was adorned with flowers and ribbons. Marinette, in her beautiful white gown, walked down the aisle. Adrien, looking dashing in his suit, had tears of joy in his eyes. Their friends and family watched with love. As they said their vows, the whole place was filled with an air of magic. And then they were pronounced husband and wife, sharing a passionate kiss as confetti rained down on them.
There is a fanfiction called 'Kagami and Adrien's Unseen Adventures'. This one takes the readers on a journey through various adventures that Adrien and Kagami have.

Well, in Adrien Agreste depressed fanfiction, it often delves deep into his complex character. His depression could be due to his strict family life, especially his over - controlling father. Fanfiction writers might explore how he copes with his dual identity as a model and a superhero. They may show his isolation and how he tries to hide his true feelings from his friends.
