I'm not sure who the main characters are as it's not specified. It could be the heroes from the Miraculous series or some original characters created for this fanfiction.
They might get seriously injured or die. In fanfiction, such a catastrophic event can lead to various plot developments, like other characters trying to rescue them or the discovery of hidden powers that help them survive.
Obviously, Marinette and Adrien would be key characters. Marinette could be the host of the sleepover, and Adrien might show up unexpectedly, either as himself or as Chat Noir. Their interactions would be the focus, whether it's some cute and awkward moments between them.
Obviously, Ladybug and Cat Noir are the main characters. Their immortality would likely be a central focus of the story. They would be the ones experiencing the changes and challenges that come with living forever.
Ladybug and Chat Noir are still the main characters. They are the ones who have to face the challenges related to the robots. There might also be new characters like the creators of the robots or people who are affected by the robotic events.
Well, Ladybug is always a central character. She's the one with the Ladybug Miraculous and the responsibility to save Paris. Chat Noir is right there beside her, with his charm and combat skills. Traibih, in these fanfictions, is often a character that adds more depth to the story. She might be a new hero or someone with a special connection to the Miraculous world. There could also be other characters like Alya, who is Ladybug's friend in the original series and might play important roles in the fanfiction as well.
Mostly, it's Ladybug and Chat Noir. However, sometimes other characters like Alya, who has a passion for journalism which can be related to detective work in some ways, might also play important roles. For example, she could help Ladybug and Chat Noir by gathering information or providing insights based on her observations around Paris.
The main characters would most likely be Ladybug and Cat Noir. They are the central figures in the original Miraculous Ladybug series, so it's logical that they would be the main focus in this type of fanfiction as well, even when they are shrunk.
Obviously, Rose is one of the main characters. And usually, Marinette and Adrien also play important roles as they are central to the Miraculous Ladybug universe. They often interact with Rose in different ways, either as friends or allies in the fight against villains.
Most likely, we'll see the Puppeteer as a central figure. Alongside her, Ladybug and Chat Noir are bound to be there as they always are to save Paris. Also, Alya might be involved as she often helps Ladybug. Since the Puppeteer has a history of using dolls, perhaps there could be a new character who is an expert in doll - making or some sort of antique doll collector who has some connection to the Puppeteer's powers or origin.
Well, the main characters are usually Marinette and Adrien. Marinette, as Ladybug, is the hero who has to save Paris from the akumas. Adrien, as Chat Noir, is her partner in fighting crime. In the Heartstrings fanfiction, they might have some new character traits or face different challenges compared to the original series. There could also be other important characters like Alya, Marinette's best friend, who might play a bigger role in uncovering secrets or helping Ladybug.
