One of the most interesting vampire characters is Remus Lupin as a full - blown vampire instead of a werewolf. It completely changes his backstory and relationships. He has to deal with different prejudices and his own new set of powers and weaknesses. Another great one is Ginny Weasley as a vampire. Her normally feisty and brave nature is transformed in a unique way when she becomes a vampire. And Bellatrix Lestrange as a vampire is often depicted as an even more terrifying and unpredictable character in fanfiction.
It could be a new character created specifically for the fanfiction. Maybe a vampire who has been living in the Forbidden Forest for years and has stayed hidden until some event brings it to Harry's attention.
It could be an entirely new character created just for the fanfiction. Maybe a long - lost wizard who was turned into a vampire and then gained enough power to become a king among them.
Van Helsing from 'Dracula' is very iconic. He's a knowledgeable and fearless vampire hunter, using his medical and occult knowledge to combat Dracula. Another is Buffy from 'Buffy the Vampire Slayer' series. She's a modern - day slayer, a girl with super strength and skills to take on vampires. And D from 'The Vampire Hunter D' series, with his mysterious dhampir nature and his cool sword - fighting skills against vampires.
Luka is sometimes a popular vampire character in Miraculous Ladybug vampire fanfiction. His laid - back nature in the original series can be an interesting contrast to his vampiric side. Fans like to explore how his musical abilities might be affected or enhanced by his new vampire nature.
The main character is most likely the 99th vampire princess. Since the title has her mentioned specifically, she should be the central focus of the story.
I don't have specific information about the author of the 'Luther Vampire Novel'. It could be a relatively unknown author or a new writer in the vampire genre. You might need to do some research in vampire - related book databases or libraries to find out.
