Perhaps she has the power of mind control. In the fanfiction, she might be able to influence the thoughts and actions of others, which could be really useful in various situations. For example, she could make an enemy vampire stop attacking her friends by simply using her mind control power.
In fanfiction related to Tsukune's powers in Rosario Vampire, writers often explore his relationship with other characters through his powers. His powers can be a source of conflict or cooperation. For instance, his growing powers might make some of his human friends wary, while also attracting the attention of more powerful vampires who want to either use him or destroy him. It's a rich area for creative storytelling.
A vampire in a Naruto fanfic might possess the power of hypnotism. This could be used to manipulate other characters, much like the Sharingan in some ways. They could also have the ability to transform into a bat - like form for quick movement or stealth. Additionally, they could have a regenerative ability that is much faster than normal Naruto characters, which is related to their vampiric nature.
Female good vampires with powers are often independent. They don't rely solely on male vampires. In some books, they are the ones leading the fight against evil. Their powers can range from being able to fly to having a sixth sense about danger. They are also known for their loyalty, especially to their friends and family. This is shown in how they use their powers to protect those they care about in the fictional worlds they inhabit.
The Sharingan in Naruto is a powerful ability that allows the user to copy jutsu, predict movements, and in some cases, use powerful genjutsu. In contrast, the pureblood vampires in Vampire Knight have the power to control other vampires. If we were to compare these in a fanfiction sense, it could lead to some interesting scenarios. For instance, a fight between a Sharingan - using character and a powerful pureblood vampire would be intense. The Sharingan user would have to rely on their combat skills and jutsu, while the vampire would use their natural abilities and control over others.
If we consider Naruto's shadow clone jutsu, as a vampire, he could create clones with vampiric powers too. Moka, on the other hand, has her unique vampire powers. They could interact in a way that Naruto's clones could be used to distract enemies while Moka sneaks up and uses her powers to incapacitate them. Also, Naruto's chakra control might be affected by his vampiric state and could be combined with Moka's energy in some new and interesting ways.
Another power that could be explored in Bella's vampire fanfiction is her control over the elements. Maybe she can manipulate fire or water to her advantage. This would add a whole new dimension to her character. For instance, she could use fire to defend herself against other vampires who are afraid of it, or use water to create barriers or distractions.
In some fanfictions, Bella has the power of invisibility. This power gives her an edge in spying or sneaking around. She can observe her enemies without being detected, which is very useful in a world full of danger like the vampire world. She might use this power to uncover plots against her family or friends.
Superboy's powers of flight and super hearing could give him an edge in a confrontation with a vampire. He could use his flight to quickly close the distance or escape from a vampire's attack. His super hearing would allow him to detect the vampire's movements even when it's trying to be stealthy. On the other hand, a vampire's ability to transform into a bat or a mist could be a challenge for Superboy. If a vampire turned into a mist, Superboy's physical attacks would be useless. But his heat vision might be able to disperse the mist. And when it comes to a vampire's hypnotic gaze, Superboy's strong will, which is a part of his overall powers, would likely help him resist it.
Kagome has her spiritual powers like purifying arrows. In the Vampire Knight world, vampires have their own abilities such as enhanced strength and speed. They could combine powers by Kagome using her purifying arrows to weaken enemies that are resistant to the vampires' physical attacks. For example, if there's a powerful dark creature, the vampires could hold it in place while Kagome fires her arrows to purify it.
