The plot would shift. In the original, Bella's transformation into a vampire was a major plot point. But if she starts as a non - human, that whole arc is removed. Instead, new plotlines could involve her exploring her non - human identity, like if she's a werewolf, dealing with pack politics or if she's a faerie, exploring the faerie realm.
If Bella is not human in fanfic, the love triangle dynamic changes. For instance, if she's a vampire, her relationship with Edward might be more of an equal power - based relationship rather than the human - vampire dynamic in the original. And her connection with Jacob would be less about protecting her as a human.
The male Bella Swan in the fanfic might face different expectations from society within the story. In the original, Bella had to deal with being the new girl in town. As a male, he might have to deal with different social hierarchies, like being part of male groups or facing different forms of competition. This would also impact the overall plot.
In fanfics, an autistic Bella Swan can significantly change the Twilight narrative. For example, her different perception of time might make her react differently to Edward's sudden disappearances. Instead of just being heartbroken in the traditional sense, she might struggle more with the disruption to her routine.
Well, it completely flips the dynamic. In the original, their relationship was central. Here, with Edward leaving Bella pregnant, it becomes a story about Bella's self - discovery. Instead of relying on Edward, she has to rely on herself, which is a huge departure from the original where she was often seen as dependent on him.
It changes it a great deal. For one, it adds a new layer of complexity to Bella's relationships. Instead of just the Edward - Jacob love triangle, now there are Jared and Paul involved. It also affects the werewolf pack dynamics as their loyalty and actions are now tied to Bella in a different way.
It changes the power dynamics. Instead of being the damsel in distress, Bella becomes a force to be reckoned with. For example, in many fanfictions, she can protect Edward instead of always being protected by him.
It gives Bella a whole new level of strength and independence. She takes charge and makes bold choices that weren't in the original.
Well, it changes the romantic aspect completely. Instead of the love triangle with Edward and Jacob, it focuses on Bella's relationships with female characters. This alters the whole dynamic of the story. For example, her interactions with her family and friends would be different as they react to her new - found sexual orientation.
Well, it completely changes Bella's family dynamic. In the original, she's a human girl with a normal family, but in this fanfiction, being Aro's sister makes her part of the vampire world from the start. This would likely change her relationship with the Cullens. Instead of being an outsider who they protect, she might have her own power and influence within the vampire community.
Well, in many Twilight fanfics, if Edward leaves Bella, she often goes through a deep emotional turmoil. She might become very sad at first, feeling a sense of abandonment. She could also be angry, feeling betrayed by Edward. And she might become more withdrawn, isolating herself from her friends and family as she tries to deal with the pain of his departure.
If Bella Swan and Sam Uley had a love story, it would turn the Twilight world upside down. Firstly, Bella's character arc would be different. Instead of being drawn into the vampire world, she'd be immersed in the werewolf pack's culture. The Cullens and the werewolves' relationship would be more complex, as the Cullens might see Bella's choice as a threat. Also, Sam's relationship with his pack might change as he'd have to balance his love for Bella with his pack responsibilities. It would be a whole new set of dynamics in the Twilight universe.
