The main characters could be Ladybug and Chat Noir, who are now experienced heroes. However, the fanfiction could also focus on a new group of heroes that they are training. These new heroes could come from different backgrounds and have unique personalities. There might also be some characters from the past that have turned into antagonists due to some past grudges or misunderstandings. And of course, the Kwamis would still be there, guiding the new and old heroes alike.
Maybe Ladybug and Chat Noir have finally defeated all the major villains and they are now retired. They could be passing on their Miraculous to a new generation of heroes. Paris has become a much safer place with the lessons they've taught about good and evil.
Obviously Ladybug and Chat Noir would be the main characters. They could be joined by other Miraculous holders like Rena Rouge or Carapace as they enter the gaming realm.
Ladybug and Chat Noir would obviously be main characters. They could be portrayed by two students in the school play within the fanfiction.
The friends of the next - generation Ladybug and Cat Noir could also be main characters. For instance, the child of Alya and Nino might have a Miraculous too. They could bring in different skills and perspectives. Maybe this character is really into technology because of their parents' love for media and music.
Ladybug and Chat Noir would likely be main characters as well. Since it's a Miraculous Ladybug fanfiction, they are important figures in that universe. They would interact with the son of the villain, either as enemies at first or as potential allies. And then there could be the villain parent. This character would have a big influence on the son's life and actions, constantly pulling him towards the path of villainy.
Adrien and Chat Noir could also be the main characters. Adrien is a model with a lot of public image to maintain, and Chat Noir is a flirty and carefree superhero. If they switched, there would be a lot of drama. Adrien might struggle with Chat Noir's more laid - back attitude towards his superhero identity, and Chat Noir would have to deal with Adrien's strict family life.
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.
