There's a fanfiction called 'The Miraculous Origins'. It delves deeper into the backstory of the Miraculous. It explores how the Miraculous were created and how they came to be in the hands of the current holders. It's a long read but worth it for fans who want to know more about the lore of the Miraculous Ladybug Cat Noir universe.
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.
Definitely Tikki and Plagg. These Kwamis are essential to the Miraculous universe. Their interactions with Cat Noir and Ladybug, as well as their own little quirks and personalities, can make for really fun fanfiction. Additionally, Sabrina, Chloe's sidekick, can be an interesting character to include. She could have her own story of breaking free from Chloe's control or getting involved in the hero - villain drama in some unexpected way.
To write a good Miraculous Ladybug Cat Noir fanfiction, you should start with a strong concept. It could be a 'what - if' scenario, like what if Ladybug and Cat Noir's identities were revealed early. Then, build your story around that. Also, pay attention to the relationships between the characters. The friendship and budding romance between Ladybug and Cat Noir are important elements. Don't forget to add some twists and turns to keep the readers interested. Maybe a character they thought was a friend turns out to be working for the villain.
One possible fanfiction could involve Chat Noir being akumatized after a major argument with Ladybug. Maybe he feels constantly overshadowed or unappreciated. The akuma could enhance his negative feelings, making him more aggressive and less in control. His powers might become distorted, and he could start causing chaos in Paris. Ladybug would then have to find a way to reach out to the real Chat Noir inside the akumatized form and purify the akuma.
She would also be very determined to bring him back to the good side. Ladybug might search for a way to break whatever spell or influence has made Chat Noir evil. She could look for a special power - perhaps from another Miraculous or a magical item - that can reverse the change. And in the meantime, she has to be careful not to get hurt by Chat Noir while still trying to protect Paris.
One great Miraculous Ladybug Chat Noir x OC fanfiction is 'The New Hero in Paris'. It has an interesting OC who has unique powers and a great dynamic with Chat Noir. The story is full of action and mystery.
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.
Well, you could have a fanfiction where Ladybug loses her Miraculous and has to rely on her wits and the help of her civilian friends to get it back. Maybe there's a plot where Chat Noir gets corrupted by an evil force, and Ladybug has to find a way to save him without using their usual powers. Also, a story where the Miraculous holders swap their powers permanently and have to adapt to new fighting styles and abilities.
Definitely Ladybug. You could show her growth from an ordinary girl to a powerful superhero. Then there's Alya. She could be interesting to focus on as she tries to uncover the identities of Ladybug and Chat Noir. And don't forget about Tikki. As Ladybug's Kwami, she has a wealth of knowledge and a unique relationship with Ladybug that can be explored in different ways in the fanfiction.
