There could also be a sidekick character who is a human beyblade expert but has to help the vampire - turned - blader adjust to the rules and culture of the beyblade world. This character serves as a bridge between the two different aspects of the story, the beyblade community and the vampire nature of the main character.
Often, there's a young beyblade protégé who discovers he has some sort of vampire connection. For example, Tyson could be reimagined as having a vampire ancestor in some fanfictions.
Often, there is the itaasu vampire itself as a main character. It might be a male vampire with a brooding and mysterious personality.
Obviously, Morty is one of the main characters. He's the one who becomes a vampire in most of these fanfictions. Rick often plays an important role too, either as Morty's protector or as someone who has to deal with Morty's new vampire state. Sometimes, other characters from the Rick and Morty show like Summer or Jerry might also be involved.
Well, of course, Harry Potter is often one of the main characters. He brings his own set of skills and his reputation as 'the boy who lived'. Then there are the vampire characters. They can be original creations or sometimes based on existing vampire lore. For example, a common type of vampire character might be a brooding, centuries - old vampire who has a lot of knowledge about the hidden parts of the magical world.
Well, of course, Conker is often the main character. Whether he's the hero fighting against vampires or a vampire himself, he's central to the story. Sometimes his friends from the original Conker games might also make appearances, like his girlfriend Berri. They could be involved in his adventures, either helping him or being in need of his help.
Well, Tsukune himself is obviously a main character. He is the Vampire Lord around which the story revolves. Then, his friends from the school like Moka are often there too. Moka has her own unique charm and powers, and her relationship with Tsukune is always an interesting aspect to explore in the fanfiction.
Well, the members of U - Kiss are usually the main characters. Each member can be given unique vampire traits. For example, one might be the strong and silent type with enhanced strength, while another could be more of a charming vampire with the ability to hypnotize.
Sonic, of course, is often one of the main characters, either as the vampire or having some sort of encounter with the vampire. And the werehog is also a main character. There could also be other characters from the Sonic universe who are part of the werehog camp.
The main characters can vary depending on the writer's preference. However, Elena is usually a central figure as she was in the original series. Her interactions with the vampires and her role as a human - turned - vampire (in some fanfics) are often explored. Damon's dark and brooding nature also makes him a favorite to write about. Additionally, characters like Jeremy, with his connection to the supernatural through his sister and his own experiences, can be a main focus in some fanfictions.
There is often a vampire protagonist. This character is usually complex, with a troubled past. They might be struggling with their vampire nature.
Often, there's the vampire cowboy himself. He's usually a complex character, strong and fearless but also dealing with his vampiric urges.
