In some fanfictions, a great plot twist is that Bella's transformation into a vampire is not as smooth as in the original story. She might struggle with a different kind of thirst that is not for blood but for something else, like the life force of plants or the energy of humans without actually drinking their blood. This would make her an outcast among vampires. Additionally, it could be that her transformation unlocks memories from a past life, which leads her to a hidden vampire society that has been lost in time and has different rules and hierarchies.
One interesting plot twist could be that Bella's transformation into a vampire gives her a unique power that no other vampire has. For example, she might be able to control the weather. Another twist could be that instead of joining the Cullen family right away, she runs off on her own to explore the vampire world. Maybe she discovers a whole new coven that has different values and ways of life compared to the Cullens.
Well, a cool plot twist might be that when Bella turns, she has a premonition of a future threat to all vampires. This makes her not just a regular new vampire but someone with a mission. Also, it could be that her transformation somehow affects the relationships in the vampire world. For instance, it could cause jealousy among other vampires who don't have a 'human - turned - vampire' in their coven. And perhaps she can communicate with animals in a way that other vampires can't, which changes the dynamics of how vampires interact with the natural world.
One interesting plot twist could be that Bella, as a new vampire, discovers she has unique powers that no other vampires have. For example, she might be able to control the elements in some way.
One interesting plot twist could be that Hermione, as a vampire, still retains her thirst for knowledge. Instead of blood, she discovers a way to feed on knowledge energy. For example, she might visit ancient libraries at night and absorb the knowledge stored in the books, which gives her a different kind of 'nourishment'. Another plot twist could be her relationship with her friends. Harry and Ron might initially be scared of her, but then they realize that she's still the same Hermione deep down. They could then team up to fight against vampire hunters who see Hermione as a threat just because of what she's become.
In some fanfics, a possible plot twist is that Bella, as a vampire, has a different sire than Edward. This could lead to a whole new set of alliances and rivalries. Maybe her new sire has a dark past or is part of a vampire clan that is at odds with the Cullens. This would force Bella to re - evaluate her loyalty and her place in the vampire world.
Well, one common plot twist could be that the kidnapper is actually a long - lost relative of Bella's with a hidden agenda. Another might be that the kidnapping was a set - up by a jealous vampire from another coven who wants Edward for themselves. And sometimes, it could turn out that Bella has some sort of hidden power that the kidnapper is trying to either use or suppress.
One common plot twist could be that the kidnapper is actually a character who was thought to be dead in the original Twilight series. This sudden revelation can completely change the direction of the story.
Well, a plot twist might be that the baby has a special connection to an ancient vampire clan that no one knew about. This could lead to a whole new storyline where they try to claim the baby. Also, Bella could experience a vision during the birth that reveals a future event that changes the course of the 'Twilight' world. Maybe she sees a great war coming and this knowledge makes everyone around her change their plans. It could also be that the baby's birth causes some sort of magical ripple effect that starts to change the abilities of other vampires in the area.
In this fanfiction, perhaps there's a plot where Bella's transformation causes a stir in the vampire community. Some vampires might be jealous that Damon turned her, while others might see her as a threat. Also, her human friends could react in different ways. Some might be scared and avoid her, while others might be intrigued and try to stay close. And Bella could have to learn how to navigate this new world of vampire politics and secrecy.
One interesting plot could be Bella's struggle to control her new vampire instincts. For example, she might have a hard time dealing with her sudden urge for blood while trying to maintain her relationships with her human friends and family.

One common plot twist could be that Bella's assassin skills are discovered by the Volturi, who then try to either recruit her or eliminate her because they see her as a threat to their power. Another might be that Bella discovers a secret society of assassins within the Twilight universe that has been manipulating the events all along, and she has to decide whether to join them or fight against them.
Often, a plot twist might involve the nature of the baby. In some fanfictions, the baby could have powers that are not just a combination of vampire and human, but something entirely new. It could be a power that is so strong it attracts other supernatural beings, not just vampires. This would change the dynamics as Bella and Edward would have to protect the baby from new threats.
