I really like 'Felix's Redemption'. In this fanfic, Felix starts off as a rather antagonistic character, but as the story progresses, his relationship with Adrian evolves. It's interesting to see how they come to understand each other better, especially in the context of the Miraculous Ladybug universe with all its magic and mystery.
Perhaps in the fanfiction, Adrian's death could be a result of a self - sacrifice. He might give up his life to save Ladybug or Paris from a great danger. This would lead to a whole new set of challenges for Ladybug as she has to deal with the loss of her partner and also continue to protect the city without him. His death could also be a catalyst for a new hero to emerge, or for Ladybug to gain new powers out of her extreme emotions.
One popular theme is family secrets. Given their family background in the Miraculous Ladybug world, fanfictions often explore the secrets that Felix and Adrian might be hiding from each other or from the rest of the world. For example, there could be secrets related to their parents' past or the true nature of their family business.
Marinette (as Ladybug) would be devastated. She might isolate herself at first, blaming herself for not being able to prevent it. Alya would be very concerned for Marinette and try to comfort her, but also be in shock at the loss of Chat Noir. Nino would probably be heartbroken as well, since he was friends with Adrian. The other classmates might be sad and confused, and there could be a general sense of gloom over the school.
Well, 'rough lemon' usually implies a more edgy or intense take. So, in 'Miraculous Ladybug Rough Lemon Fanfiction', there might be more complex or darker storylines compared to regular fanfiction. It could involve more conflict or non - traditional relationships.
In my fanfiction, Nino gets the chance to become a temporary superhero. He is given a Miraculous - like device by an unknown entity. With this, he transforms into a hero with a unique look and powers. His main power is the ability to create force fields made of sound. He uses this power to protect the city from Hawk Moth's akumas and to support Ladybug and Chat Noir during tough battles. Nino also has to deal with the everyday problems of being a hero, like keeping his identity secret from his friends and family.
In an akumatized Ladybug fanfiction, the akuma might enhance her powers in unexpected ways. For example, her Lucky Charm could become a more powerful and unpredictable object. Her akumatized form might also have a darker and more menacing look, perhaps with a more aggressive fighting style. Writers could explore how the heroes and villains interact with this changed Ladybug.
He could be shocked at first. I mean, he has been so close to Marinette all this time without realizing she was Ladybug. His reaction might include disbelief and then a quick acceptance as he starts to piece things together in his mind.
