There are many interesting fanfictions about Marinette and Luka. Some might focus on their relationship development outside of the superhero chaos. For example, a fanfiction could explore how they go on a simple date, sharing their interests like Marinette's fashion design and Luka's music.
In a fanfiction, Luka as the snake could have a special connection with the Miraculous that goes beyond what we've seen in the show. He might be able to communicate with the kwami in a different language or understand its deeper secrets. This could lead to him playing a more crucial role in the fight against Hawkmoth. He could also use his musical talent in combination with his powers. For instance, he plays a certain melody on his guitar that enhances his snake powers, like making him faster or stronger.
Well, a fanfiction about Luka getting akumatized might start with a misunderstanding. Maybe he sees Marinette and Adrien together and misinterprets their relationship. As an akumatized character, he could have a really cool and menacing design. His akuma form might be named something like 'Melodic Mayhem' and his powers could involve disrupting the harmony around him, not just in a musical sense but also in people's relationships. This would force Ladybug and Chat Noir to think differently when fighting him.
One common theme is the exploration of their unrequited love. In the show, Marinette has a crush on Adrien, but in fanfictions with Luka, she may start to realize her feelings for him. Another theme is the power of music. Since Luka is associated with music, it often plays a role in bringing them closer, like Luka writing a song for Marinette.
The plot could involve Luka's snake powers being stolen. He then has to team up with Ladybug and Chat Noir to get them back. Along the way, they discover that the thief has a connection to an ancient Miraculous holder. Luka has to rely on his wits and his natural snake - like instincts to track down the thief.
One interesting plot point could be Luka's internal struggle. Even as an akumatized villain, his good nature might be trying to break through. For instance, he might hesitate to cause real harm to Ladybug or Chat Noir. Another point could be the way his friends try to reach out to him. Juleka might be especially desperate to bring her brother back, and this could lead to some really heart - wrenching scenes. Also, his akuma form's powers evolving as his emotions intensify during the fight would be an exciting plot element.
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.
There are indeed. Fanfiction writers often come up with creative stories involving the wolf miraculous in the Miraculous Ladybug world. They might explore how a new holder of the wolf miraculous interacts with Ladybug and Chat Noir. It could be about a character who discovers the power of the wolf miraculous and has to learn how to use it to fight against Hawk Moth's akumas.
