Some fanfictions might handle it by exploring Adrien's inner turmoil in great detail. They could show his gradual descent into hopelessness through his thoughts and interactions. For instance, by depicting his lonely nights and how he contemplates his worth.
In such a fanfiction, one possible reason could be the intense pressure he faces as a model and son. Constantly having to meet high expectations and having little personal freedom might drive him to despair. For example, his father's strict control over his life and his public image could make him feel trapped.
Moreover, in certain fanfictions, Adrien's chastity can be a plot - driving force. It could be that an antagonist targets his chastity, seeing it as a weakness or something to be exploited. This creates tension and conflict in the story, as Adrien has to fight to preserve his values while also protecting the city as Chat Noir.
A great fanfiction idea could be that Adrien and Kagami are paired up for a school project. As they work on it, they start to realize that they have more in common than they thought. They could share their dreams and fears, and this new - found closeness might make Adrien question his feelings for Ladybug a bit more.
One possible story could be that Adrien gets akumatized because he feels constantly overshadowed by Ladybug. In this fanfiction, Hawkmoth might prey on his insecurities. As an akumatized form, Adrien could have enhanced physical abilities like super strength and speed. His akumatized look might be a dark version of his Chat Noir costume, with a more menacing appearance.
Adrien in fanfiction is often the sweet, kind-hearted model who is also a superhero. He's the boy next door type. Felix, on the other hand, is usually characterized as more of an enigma. He may be more calculating and less open than Adrien.
His character could become more withdrawn. Normally, Adrien is charming and outgoing, but drugs in a fanfic might make him isolate himself from others as he gets caught up in this new and dangerous world.
There are many interesting fanfictions out there about Adrien's car in Miraculous Ladybug. Some might focus on Adrien using his car to go on secret adventures while being Chat Noir. For example, he could use the car to quickly reach a location where an akuma attack is about to happen. The car could also be a place where he has some private moments to think about his double life and his feelings for Ladybug.
There's also 'Marinette's Hidden Talents'. In this fanfic, Adrien discovers some unique skills that Marinette has been hiding. It's a really interesting take as it builds on their characters and the bond between them. It has a lot of cute moments and a bit of mystery too.
I think Adrien's confession in fanfiction can be really exciting. It often adds a new layer of depth to his character. In some fanfictions, his confession might be a long - awaited moment for Ladybug, and it can lead to some really sweet and romantic scenes. For example, the way he might finally express his true feelings after many seasons of pining can be very heart - warming.
Another amazing one is 'A Different Perspective'. This fanfiction shows the story from Adrien's point of view. It gives new insights into how he sees Marinette and how his feelings for her start to change from just friendship to something deeper.
