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.
Karin herself is very interesting. Her kind - hearted nature despite being a vampire makes her stand out. Then there's Kenta, her love interest. He's a normal human but he accepts Karin for who she is. Their relationship dynamic is really engaging. Another interesting character is Anju, Karin's sister. She has a different personality compared to Karin and her actions often lead to interesting plot developments.
Zero Kiryu can be really interesting. His struggle with his vampire side in the original 'Vampire Knight' makes him even more complex in fanfiction. If reborn, he could have a whole new perspective on his identity. Another one is Kaname Kuran. His powerful and mysterious nature gives a lot of room for creative interpretations in fanfiction. A reborn Kaname might have different motives or relationships.
Obviously, Hinata herself is a very interesting character in these fanfictions. Her character from her original source material brings a certain innocence and determination that gets explored in new ways in the Vampire Knight setting. Then there are the vampire characters like Kaname Kuran. His complex personality and his relationship with Hinata can be really captivating in fanfiction. Another interesting character could be Zero Kiryu, especially when his story intersects with Hinata's, given his own struggles with his vampire side.
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.
Edward is also a fascinating character. His struggle with his vampire nature and his growing feelings for Bella can be explored in more depth in the fanfiction. Maybe we'll see new aspects of his character, like his relationship with his vampire siblings in the context of Bella being in their lives.
Rose is always an interesting character to focus on. Her strong - willed nature and her growth throughout the series make her a great centerpiece for any fanfiction. You can explore her further development as a dhampir and her relationships in more depth.
Tsukune himself is quite interesting. He's a human in a world full of vampires, which makes him an outlier. His journey of adapting to this new world and developing his powers is always engaging. Moka is also a great character. Her dual personality, with the sweet outer self and the more powerful vampire self, adds a lot of depth. Inner Moka especially is a force to be reckoned with. And then there's Kurumu, the succubus. Her pursuit of Tsukune in the fanfiction can lead to some really fun and flirty storylines.
Lestat is definitely one of the most interesting. His flamboyant and often self - centered nature provides a lot of material for fanfiction writers. Writers can explore his complex relationship with other vampires, like Louis. Another interesting character is Claudia. Her tragic story as a child - turned - vampire can be delved into more deeply in fanfiction, exploring her feelings of being trapped in a child's body while having an adult's desires.
Rose Hathaway is really interesting. She's a strong and feisty Dhampir. Her loyalty to her best friend Lissa and her complex relationship with Dimitri make her stand out. Dimitri also is a great character. He's a skilled Guardian with a sense of honor. And Lissa, the Moroi princess, is interesting with her powers of spirit and the way she copes with the pressures of her position.
I think Klaus Mikaelson is one of the most interesting characters. He's an original vampire, extremely powerful and feared. His backstory is filled with tragedy and his quest for power and revenge shapes many of the events in the story. Caroline Forbes is also great. She starts as a rather shallow character but her transformation into a vampire and her growth into a strong, independent woman is really engaging to follow in the novel.
