In Miraculous fanfics, the concept of Adrien and pain often goes hand - in - hand. If 'blackness' is introduced, it could be a symbol of something negative that's causing him pain. It might be a dark power that he's trying to resist, or it could be emotional pain from a past event that's now resurfacing and is symbolized by this 'blackness'.
The connection between Adrien, blackness, and pain in a Miraculous fanfic can be complex. 'Blackness' could potentially refer to a state of mind, like depression or a sense of being lost. This state could then lead to Adrien experiencing pain. For instance, if he feels isolated or different from others due to this 'blackness' within him, it can cause emotional distress which is the pain aspect in the fanfic.
It could be that the 'blackness' is a curse or some sort of negative energy that's afflicting Adrien, thus causing him pain. For example, it might be a magic - based affliction that saps his strength and causes him physical and mental pain.
There's a fanfic called 'Female Adrien's Adventure'. It's set in an alternate universe where Adrien is female. The story focuses on her as a Miraculous holder and how she copes with the responsibilities. It has some really cool action scenes and also some sweet moments where she interacts with her friends. It's a must - read if you like this concept.
In a fanfic, Adrien might collapse injured because of some sort of curse or negative magic. For example, a new villain discovers a way to target the Miraculous holders directly. Adrien, being Cat Noir, is affected and his powers start to backfire on him, causing him to collapse. His partner, Ladybug, then has to figure out how to break the curse and save him.
This event in the fanfic could also lead to new characters emerging. Maybe someone would try to take on Ladybug's mantle in a different way. Or new villains could rise, seeing the opportunity in the chaos. The magic of the Miraculous might be affected too. Since Ladybug was an important part of the magical balance, her death could have unforeseen consequences on the powers and the Miraculous themselves.
A good fanfic in this case often has strong character development. For example, the female Adrien should have a distinct personality that still retains some of the charm of the original character. It should also have an engaging plot. Maybe she has to face different challenges because of her gender in this new version.
One possible plot could be that Adrien gets hit by a villain's special power that makes him go limp. His friends in the Miraculous team then have to find a way to reverse the effect while protecting Paris from other threats. Maybe Ladybug has to use her creativity to come up with a new power - up or a new strategy to save him.
It could also be a case of misinformation in the fanfic. Adrien might think Ladybug has turned evil or is about to cause great harm. So, in his attempt to save the city or his loved ones, he makes the tragic decision to kill her, believing it's for the greater good.
Another possibility is that an akumatized character becomes the main antagonist in this fanfic. For instance, a jealous classmate of Adrien's who gets akumatized. Their power could be to drain the energy or mobility of others, and they choose to target Adrien first. This would create a more personal and complex conflict within the story, as the akumatized character has a pre - existing relationship with 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.
Well, in the fanfic, Adrien could be in the rubble hospital due to a battle gone wrong. Maybe he got seriously injured while fighting an akuma. The hospital setting might be a place for him to have some self - reflection and also for his relationship with Ladybug to develop further, like she could visit him secretly.
