In this type of fanfiction, anti - heroes can be quite popular. They might be characters who are not entirely good but are forced to do the right thing in the face of the dark elements in the story, like a thief who has to help save the town from the dark snow - related threat. These characters add an interesting layer of complexity to the story.
Some of the native characters of the snowy setting can also be popular. For example, an old hermit who has lived in the mountains covered in snow for years and has knowledge about the dark secrets of the snow. His wisdom and connection to the land can be a focal point in the fanfiction, and his interactions with other characters can drive the story forward.
There are also side characters in Dark Dark Fruit fanfiction that gain popularity. These could be characters who are friends or allies of the Dark Dark Fruit user. They might have unique abilities that complement the powers of the Dark Dark Fruit, and their relationships with the main character add depth to the story.
In 'Jon Snow Dragons' fanfiction, Bran Stark could be a significant character. With his greenseeing abilities, he might foresee the importance of Jon's connection with the dragons. Tyrion Lannister could also be there, using his wits to advise Jon on how to handle the dragons or deal with the political implications of having such powerful creatures by his side. And of course, the dragons themselves can be considered characters in a way, each with their own personalities and quirks.
Mercury herself is of course a central character. Often, her friends or allies from the original story also play important roles. For example, if it's in a certain universe, characters like Sailor Moon might be in the fanfiction trying to save or stop Mercury.
The Strangers are also popular. Fanfiction writers might explore their culture, their reasons for creating the Dark City, and their relationship with the humans from a different perspective. They can be portrayed as more sympathetic or even more menacing in fan - created stories.
In dark arthur fanfiction, Arthur is the main focus, of course. But characters like Guinevere can also be important. In some stories, she has to deal with the changed Arthur. Lancelot might also be involved, perhaps as a rival or an ally in the complex world of a dark Arthur. Mordred is another character that often shows up, as his relationship with Arthur is already complex in the original legend and can be further explored in the dark versions.
Often, the main protagonists from the original Dark Skies are popular in fanfiction. They are the ones that fans like to expand on and give new adventures to.
Often, the main protagonist from the original Dark Labyrinth is still popular in fanfiction. Their journey through the labyrinth, facing various obstacles, makes them a central figure. For example, if there was a brave adventurer in the original, they would be a key character in many fanfictions.
I'm not sure as I haven't read the actual story. But it could be a lone traveler who is caught in the dark snow and has to find a way out.
The main characters would likely still include Snow White and the Evil Queen. But in a dark version, there might be more focus on the Huntsman who could be a more developed character with his own moral dilemmas. And of course, the dwarfs would also be main characters, but perhaps with different personalities, like being more gruff or having their own agendas.
I don't know as I haven't read the story. It could be a lone adventurer in the snow, or a group of friends who get into trouble in the snowy environment.
