Zero is a top choice. Writers can explore his internal struggle with his vampiric urges while still trying to uphold his duty as a hunter. Yuki is often written about because of her unique position between the two worlds. She can be a bridge or a source of conflict. Kaname, with his air of mystery and his long - standing influence in the vampire community, is also highly popular. Additionally, the Night Class students like Aidou are also quite popular as they add an element of charm and playfulness to the otherwise often - dark stories.
Zero is definitely one of the most popular. His complex personality, being a vampire hunter yet having the vampire curse within him, makes for great storytelling. Yuki is also popular. Her torn feelings between her human side and her connection to the vampires, especially Kaname, give a lot of room for emotional exploration. Kaname himself is a favorite. His mysterious nature and his role as a powerful vampire leader provide many angles to write from.
Zero is often very popular. His complex character, being a vampire hunter with vampire blood himself, makes him full of contradictions and depth. Fans are intrigued by his internal struggle between his human side and the vampire instincts within him.
Louise is at the top of the list. Her growth throughout the series, from a somewhat clumsy and insecure mage to a more confident one, is fascinating to write about. Saito, as the familiar of Louise, is also a key character in fanfiction. His ability to adapt to the magical world and his unique skills, like his swordsmanship, are often focused on. And Tabitha is popular too. Her quiet and mysterious nature, along with her powerful magic, gives writers a lot of room to explore her backstory and her relationships with the other characters.

One possible fanfiction could be about Kiryu's backstory in 'Vampire Knight Zero'. Maybe it delves into his early days before coming to the main events of the story, his family life, and what led him to be the person he is in the series.
A fanfiction could explore Kaito's past and how it intersects with Zero's. Maybe Kaito has some secrets that could either help or hinder Zero in his fight against vampires. It could be a story full of mystery and revelations as they dig deeper into their intertwined histories.
Fine is also a popular choice. Her position as a vampire yet having some sympathy towards humans offers a lot of room for exploration. Fanfiction can delve into her internal conflicts, such as her loyalty to her vampire kind and her growing connection with humans.
Rose Hathaway is a very popular character to write about. She's strong, brave and has a complex personality. Writers can explore her further adventures or her relationships in different scenarios.
One of the popular themes is the complex relationship between Zero and Yuki. In many fanfics, it delves deeper into their unspoken feelings. Another theme is the struggle against the vampire world's rules. Since the Vampire Knight series has a strict vampire - human hierarchy, fanfics often explore how Zero and Yuki might break or change these rules. Also, the theme of self - discovery is common. As both characters grow throughout the series, fanfics expand on their individual journeys of finding out who they really are and how their relationship with each other affects that discovery.
One popular trope is the 'forbidden love' trope. Given Zero's status as a vampire hunter and his vampire blood, a relationship with a pure - blood vampire like Yuki can be seen as forbidden. Another trope is the 'redemption' trope. Writers often explore Zero's journey to redeem himself, either from his past actions or from the 'curse' of his vampire blood. It adds depth to his character.
Yes, there might be. The 'Vampire Knight' fandom is quite large, and it's possible that some fans have created fanfiction involving Zero being in a situation related to pregnancy. However, not all fanfictions are easy to find, and the content can vary greatly in terms of quality and adherence to the original story's themes.
