Merlin is often the central figure in these fanfictions as his magic can be used to drive the plot forward. Sting could be the action - oriented character, always ready for a fight. Serket might be the more enigmatic one, with knowledge or powers that are not immediately obvious. Together, they create a dynamic trio in the fanfiction world.
One great Merlin Serket Sting fanfiction could be a story where Merlin uses his magic to help Sting and Serket on a quest. Maybe they are on a mission to save a magical realm that is being threatened by dark forces. Merlin's powerful magic, combined with Sting's combat skills and Serket's mysterious abilities, makes for an exciting adventure.
In the 'the sting novel', the main characters could be very interesting. There might be a character who has been wronged in the past and is now seeking revenge through this sting. There could also be an authority figure who is either in on the sting or is trying to stop it. And of course, there would likely be the team members involved in the actual execution of the sting, each with their own skills and personalities that contribute to the overall success or failure of the operation.
Maybe Rogue could be a supporting character. He could be the one who gives Sting some advice about his married life with Lucy, based on his own observations of their relationship.
Obviously, Merlin is the main character. As a prince, he has a central role in the story. Arthur is also often a major character. Their relationship changes and develops in different ways. For example, Arthur may have to deal with Merlin being his equal in status now. Gwen might also be an important character, perhaps as Merlin's ally or love interest.
In 'Balinor Merlin' fanfiction, the two central characters are Merlin, who is constantly trying to protect Camelot and Arthur, and Balinor. Balinor is important as he is not only a dragonlord but also has a connection to Merlin. He passes on his knowledge and power to Merlin, which makes their relationship a key part of the fanfiction. Their interactions, the things they learn from each other, are what drive the stories in most of these fanfictions.
Well, obviously Merlin and the prince are the main characters. Merlin is often depicted as a powerful wizard with a kind heart, and the prince can vary in personality depending on how the author writes him. Sometimes he's brave and headstrong, other times more cautious and diplomatic.
The main characters are obviously Lamia and Merlin. Lamia is often depicted as a unique and mysterious character with her own set of powers and abilities. She might have a connection to the more shadowy or less - known aspects of magic.
I don't have enough information to determine the main characters. It could be a hero who has to face the manticore and its sting.
Obviously, Merlin and Arthur are the main characters. Merlin, with his magical abilities and his role as Arthur's servant and friend. Arthur, the king who is destined for great things and has a complex relationship with Merlin.
Most likely Merlin is one of the main characters. And probably there are some characters related to the dragoons, like their riders or leaders, but without reading the fanfiction it's hard to say for sure.
