In a fanfiction, a character's personality after becoming a vampire can transform significantly. Let's say a character was a social butterfly before. As a vampire, they might become more nocturnal and withdrawn from their old social circles. Their sense of time could change, making them more patient or impatient in different ways. They could also develop a sense of superiority due to their enhanced abilities. Their emotions might be more intense, especially when it comes to anger or passion. And they may start to view humans in a different light, perhaps as prey at times, but also with a newfound understanding of human fragility.
A once shy character might become more confident and assertive as a vampire. The newfound power can boost their self - esteem. For example, if a meek person is turned, they could start taking charge in situations. Also, they might become more secretive because they have to hide their vampire nature. Their values could shift too, like their view on life and death due to their immortality.
They might become more withdrawn. Since vampires are often associated with secrecy, the maknae could start to keep their thoughts and feelings to themselves more. For example, they may not share their newfound struggles with bloodlust with their friends right away.
Percy might become more brooding. As a vampire, he's now part of a world that's often associated with darkness and mystery. He may also become more possessive, which is a common trait among vampires. For example, he could be overly protective of his territory or the people he cares about.
His personality might become more brooding and mysterious. Vampires are often associated with being deep thinkers and having a certain allure. JK might be more withdrawn as he tries to hide his new nature from others.
He may become more solitary. Since vampires are often depicted as loners in many stories, Jacob could start to distance himself from his former friends and allies. His personality might also become more brooding and mysterious, as he tries to hide his new vampire nature from those around him.
It's likely that Naruto, now a girl, would be more perceptive. In the male form, he was sometimes oblivious to the subtleties of relationships. As a girl, she might pick up on the unspoken feelings between characters more easily. This could lead to her playing a different role in the group dynamic, perhaps becoming a mediator or a source of emotional stability within the team.
The character might become more in touch with their emotions. As a girl, they could be more likely to express vulnerability. For example, they might cry more easily or be more open about their feelings of fear or sadness.
He'd probably be more innocent. The snobbish and often cruel Draco we know would be replaced with a more naive and curious version. He might not have the same prejudices as he does as a teen or adult.
His diet changes. Instead of regular food, he now has a craving for blood. His sleeping patterns might also be different. He could become more nocturnal.
His relationship with Tails would be strained. Tails would be confused and a bit scared at first. Sonic would have to hide his new vampiric urges from Tails, which would create distance between them. With Knuckles, there might be more of a distrust as Knuckles is very protective of their world. Knuckles might see Sonic as a threat now that he's a vampire.
Naruto's character would change in several ways. His sense of loyalty would be tested. As a vampire, he might be more tempted to put his own needs (like finding blood) first. Emotionally, he could become more brooding. He's used to being the energetic one, but now he has to hide his vampiric nature. This could lead to him distancing himself from his friends. Also, his ninja skills would take on a different aspect. His stealth might improve because he has to move in the shadows more, but his use of some jutsu that require sunlight or open areas could be compromised.
