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 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.
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.
Well, she could have enhanced strength like other Originals. Since she was already quite tenacious as a human, as a vampire, her strength might be off the charts. Maybe she could also have a unique form of mind control, not just over humans but also over other vampires. This could be related to her empathetic nature as a human, now amplified as a vampire.
She could have the power of elemental control, such as controlling fire, water, air or earth. For example, if she can control fire, she could use it for protection or to create light in dark places. If it's water, she might be able to manipulate it to form barriers or even use it to heal. The power of air could let her fly or create strong gusts of wind to blow away enemies. And with earth control, she could make the ground move or create shelters out of rocks and soil.
Well, it might be the way the relationships are portrayed. If it's a different kind of vampire fanfiction, the relationships Bella has with other characters, be it vampires or humans, could be very different. For example, instead of the typical love triangle, there could be a complex web of alliances and rivalries that Bella is at the center of, making the story stand out.
If she has a powerful combat - related power like super strength, it might make other characters either fear or respect her more. They would be cautious around her, knowing that she could easily overpower them if she wanted to.
One common power she might be given is telekinesis. This allows her to move objects with her mind, which could be really useful in various situations in the fanfiction world, like during battles or when she needs to retrieve something out of reach. Another power could be enhanced intelligence, beyond what she already has in the original story. This would make her an even greater force to be reckoned with when it comes to solving complex magical problems or outwitting her enemies.
She might discover her powers accidentally. For instance, she could be in a moment of extreme danger or stress and suddenly find herself using the power without even realizing it at first.
He could have the power of lightning, like Zeus. Maybe he can control it better than other demigods. Also, he might have enhanced strength and speed, similar to Zeus's own capabilities.
He might have had the power of super speed. This would allow him to move from one place to another in an instant, which would be useful for hunting or escaping danger.
