It can create a sense of urgency. Other characters will then be focused on helping him recover. Ladybug, for instance, might be more determined than ever to defeat the villain responsible. It can also lead to character development for Adrien. He might have to face his own vulnerability and learn to rely on others more while he's injured.
When Adrien is wounded in Miraculous fanfiction, it usually drives the plot forward. It makes the situation more serious and tense. His injury can be a catalyst for the other characters to come together and work towards a common goal, like finding a way to heal him and prevent further harm. It also gives the author a chance to explore different aspects of the characters. For example, how Chat Noir's enemies react to his weakened state, or how Ladybug copes with the fear of losing her partner.
It can create a sense of suspense. The other characters will be worried about him and the readers will be eager to know what will happen next. For example, if Ladybug sees him motionless, she'll try to figure out what's wrong and how to help him, which drives the plot forward as she investigates.
It could change the power dynamics. If he's severely wounded, Ladybug might have to take on more of the hero duties alone, which could lead to her making some hasty decisions. This might put Paris in more danger as she doesn't have Chat Noir to balance her out.
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.
In many fanfictions about Lila and Adrien, their relationship can be quite complex. Sometimes, Lila tries to manipulate Adrien to get closer to his famous family or for her own gain. But Adrien, being the kind-hearted person he is, might initially be deceived by her lies, only to gradually realize her true nature as the story progresses.
Well, in this fanfiction about Adrien's confession, it could go in different directions. If it's set during a battle, he might blurt it out unexpectedly. For example, he thinks they're about to be defeated by an akumatized villain and he doesn't want to die without Marinette knowing how he feels. Or it could be a more planned confession, where he has prepared a whole speech and even gets her a special gift, like a handmade charm related to their Ladybug and Chat Noir adventures.
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.
In an Adrien's mom fanfiction, she might have left behind secrets. For example, she could have hidden some important Miraculous or knowledge. The story could revolve around Adrien discovering these secrets and learning more about his mother, which in turn helps him in his battles as Chat Noir.
If Adrien is in the hospital, it could create a sense of urgency for Ladybug. She might be more determined than ever to defeat the villains on her own, as she doesn't have her partner by her side. This could lead to her making some risky decisions in battles. Also, she would probably be worried about Adrien's well - being, which could affect her focus during normal life situations as well.
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.
