The appeal lies in the contrast of their personalities. Marinette is often clumsy and sweet, while Kagami is more stoic and direct. When they come together in fanfiction, it creates an interesting dynamic. For example, in many fanfics, Marinette's creativity and Kagami's discipline complement each other.
Some popular Marinette x Kagami fanfictions often explore their relationship development outside of their rivalry for Adrien. One good one might be 'The New Bond' which delves into how they start to understand each other's insecurities and form a deep friendship that could potentially turn into more. It shows their shared love for fencing and how that becomes a common ground for them.
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.
Well, this kind of fanfiction could start with Marinette making a mistake while using the Miraculous. Then she finds herself in the form of a Kwami. She might be really tiny and have to find ways to get around. She could hitch rides on people's shoulders or use her small size to her advantage when it comes to spying on Hawk Moth. And she would definitely have to deal with the fact that she can't just transform back into her normal self right away, leading to all sorts of comical and tense situations.
One possible fanfiction could be about Marinette's daily life with Tikki. For example, Marinette could be having a tough day at school, getting bullied by Chloe. Tikki, being her kwami, tries to cheer her up by suggesting they make some special macarons. They then spend the evening in Marinette's room, sharing stories and laughing, which helps Marinette forget about her bad day.
One possible scenario in a fanfiction could be that Lila finally realizes the error of her ways and decides to make amends with Marinette. She might see how Marinette's kindness has always been genuine despite her lies, and they could gradually become friends. This would be a big character development for Lila.
A really interesting fanfiction idea could be that Lila and Marinette switch personalities for a day. This would be a comical yet thought - provoking situation. Lila would have to deal with Marinette's responsibilities and kindness, while Marinette might struggle with Lila's devious ways. It could lead to both of them having a new perspective on each other.
One common plotline is about Luka helping Marinette deal with her feelings for Adrien. He becomes her confidant and through that process, they start to develop deeper feelings for each other.
It could be part of a plot device to show that she's being affected by a new villain's power. Maybe the villain has a power that makes people feel nauseous or sick, and Marinette, being Ladybug, is one of the first to be targeted. This would create a sense of urgency to find a way to counter the villain's power.
A simple reason for Marinette's depression could be the stress of her double life. Juggling school, friends, and being Ladybug is just too much for her, so she gets depressed.
