No. In the normal 'Miraculous' series, Cat Noir is a superhero, not a criminal. Fanfiction might deviate from the original, but the general perception of his character is heroic. So, just because it's a fanfiction doesn't mean he's a criminal.
I really like 'The Hidden Bond'. In this fanfiction, Marinette discovers a new side to Cat Noir that she hadn't seen before. It's full of cute moments and some really well - written dialogue. It also has an interesting plot that keeps you hooked from start to finish.
No, it is not appropriate. 'Miraculous Ladybug' is a popular animated series aimed at a wide audience including children. Writing sexual fanfic about the characters goes against the family - friendly nature of the show and can be considered inappropriate and disrespectful to the original work and its fans.
One common theme is the discovery of their true identities. Since they don't know each other's secret identities in the show, a lot of fanfiction focuses on how they find out about each other. Another theme is their relationship development, from friends to something more romantic.
Marinette and Cat Noir have a complex and endearing love story. Marinette is in love with Adrien, not realizing that Adrien is Cat Noir. Meanwhile, Cat Noir is drawn to Ladybug, who is actually Marinette in disguise. They fight side by side against villains in Paris. Their relationship is filled with misunderstandings, yet there are also tender moments when they see the good in each other. It's a love story that is slowly evolving as they get to know each other better in their superhero and civilian identities.
One interesting Marinette and Cat Noir fanfiction could be where they have to face a new villain that has powers they've never encountered before. In this story, Marinette might struggle with her identity as Ladybug while also dealing with her feelings for Cat Noir. Another could be a time - travel fanfic, where they go back in time and meet their predecessors as superheroes.
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.
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.
One key moment is when they first fight together as Ladybug and Cat Noir. It's the start of their relationship as superhero partners. Another is when Cat Noir saves Marinette in her civilian form, which shows his care for her without knowing she's Ladybug. Also, the times when Marinette as Ladybug has to rely on Cat Noir during tough battles are important. These moments build the foundation of their love story.
