Stiles is the central figure in this fanfiction. Since he's a born vampire, he has his own set of characteristics and story arcs. His father could also be a significant character. In many fanfictions, the relationship between Stiles and his father is explored, especially when his father starts to suspect that something is different about his son. Additionally, if there are any vampire mentors or antagonists in the story, they would be main characters as well. They would either guide Stiles in his vampire journey or try to stop him from achieving his goals.
The main character is Stiles, being a born vampire. However, in a fanfiction, there could be a love interest for Stiles. This character could be someone from his human life before he fully embraced his vampire side, or it could be another supernatural being. This love interest would be a main character as their relationship would shape Stiles' decisions and actions. Also, any vampire elders or leaders in the story would be main characters. They would have their own agendas regarding Stiles, whether it's to protect him, use him, or get rid of him.
There could also be some sort of vampire elders or leaders that are part of the story. Since Edward is a born vampire, they might be interested in him or have some sort of plan regarding him. Their presence would add to the complexity of the story and the relationships within it.
Well, Bella is obviously one of the main characters. Since it's about her being born a vampire, she will be central to the story. There might also be other vampires that she interacts with, like the Cullens if it follows the Twilight universe to some extent.
One possible interesting plot line could be Stiles struggling to hide his true vampire nature from his friends. For example, he might have to constantly come up with excuses for his super strength or aversion to sunlight. Another could be his discovery of an ancient vampire prophecy that he is a part of, leading him on a journey to fulfill it or avoid it. Maybe he also has to deal with vampire hunters who are specifically targeting him because of his unique 'born vampire' status.
Obviously, Harry Potter himself would be the central character as he is the one undergoing the transformation into a born vampire. His friends like Hermione and Ron would also be important characters. They would likely play a role in either helping Harry adjust or being conflicted about his new state.
Stiles is a must - have main character. Then, depending on the direction of the fanfiction, characters like Simon Lewis could be important. Since Simon is a vampire in the Shadowhunter universe, his interactions with Stiles, who is new to this world, could be really interesting. Also, characters like Luke Garroway, the werewolf, might play a role, especially if the story involves the relationships between different Downworlder groups and Stiles' place in all of that.
In many 'Stiles is not human fanfiction', Malia could play a significant role. Given her own complex backstory and her were - coyote nature, she might be able to relate to Stiles in some ways if he's not human. She could either help him adapt to his new state or be in conflict with him. Kira could also be involved. Her kitsune powers and her kind nature might lead her to try and understand Stiles. And the Sheriff, Stiles' father, is bound to be in the story. His relationship with Stiles would be put to the test as he discovers his son is not what he thought he was, and he'd have to deal with his own emotions and the potential danger that Stiles' non - human nature could bring.
Another vampire, an older and more powerful one, could be an antagonist. This vampire might see Percy as a threat to his power or territory. Maybe he wants to either kill Percy or make him submit to his rule.
The main characters are Stiles and the Cullens. Stiles is known for his ability to adapt in strange situations. When he meets the Cullens, their interactions will be centered around how they deal with each other's differences. The Cullens' vampiric abilities and Stiles' human (or whatever he is in his original context) nature will play a big part in their relationships in the fanfiction.
Well, obviously Stiles is one of the main characters. He's the one being hurt by the pack. The members of the pack would also be main characters, though we don't know exactly which ones without more context. It could be Scott, as he's often a central figure in the pack. There might also be other characters like Derek who could be involved in either causing the hurt or helping Stiles deal with it.
Stiles is the key character here. He's the one through whose perspective we usually experience the story. In the pack, Scott is a must - he's the werewolf who has a long - standing friendship with Stiles. Derek, with his alpha - like presence, also plays a major role. Additionally, characters like Allison, who has her own arc related to the supernatural world, could be part of the main cast as well. They all interact with Stiles in different ways when he meets the pack.
