Twilight's friends like Pinkie Pie, Rainbow Dash, Rarity, Fluttershy, and Applejack can also be part of these fanfictions. They might be shown in flashbacks or回忆 related to Twilight's past, perhaps showing how they first met or how Twilight's view of them changed as she got to know them better over time.
Edward is often involved. Since he's so close to Twilight, he would be there to support her or sometimes be a source of conflict as he tries to help in his own way but might not always understand what she's going through. Bella's family, like Charlie, could also be main characters. Charlie might notice the changes in Twilight and try to figure out what's wrong. And then, her vampire friends like Alice could play a significant role. Alice might use her ability to foresee things related to Twilight's PTSD, either to help or sometimes make things more complicated.
Bella and Edward are often main characters in such fanfiction. Since their relationship is central in the original Twilight series, in fanfiction about sacrifices, they could be the ones making sacrifices for each other. For example, Edward might sacrifice his vampiric nature to give Bella a more 'normal' life if she so desires.
Often, the reincarnated human is a main character. They are the ones going through the big change and experiencing the new world. Then there are the regular MLP characters like Twilight Sparkle, who might help the human adjust to the pony world. Pinkie Pie could also be involved as she's always friendly and curious, so she'd likely be interested in the human's story.
Her friends like Pinkie Pie, Rainbow Dash, Applejack, Rarity and Fluttershy are likely to be main characters. Pinkie Pie might bring her usual cheer and parties to celebrate Twilight's new form. Rainbow Dash could be both impressed and a bit competitive, trying to keep up with Twilight's new abilities in her own way. Applejack would offer her down - to - earth advice and support. Rarity might be excited to create new outfits for Twilight as an alicorn. And Fluttershy would be there with her gentle nature, providing a calming presence.
The Volturi leaders also frequently show up in these fanfictions. Aro, Caius, and Marcus. Their actions and decisions can be completely different in an alternate ending. They could be more benevolent or perhaps more devious. Their relationship with the Cullen family and Bella can take on new twists and turns.
Bella herself can also be part of these fanfictions in terms of how she reacts to the muscle growth of the male characters. Her perspective, whether it's admiration, fear, or something else, can add depth to the story. Also, sometimes in unique fanfictions, she might even have some form of power - related muscle growth herself.
The Cullen family members are often main characters. Edward, with his brooding nature and ability to read minds, is likely to be involved. Bella might also be there as she is closely tied to the family. And Carlisle, being the patriarch, often plays a crucial role.
Ron could also be there. He might be in charge of something like the Gryffindor Quidditch team or be a part - time teacher teaching the younger students about the magical history of the Weasley family's inventions. His humor and loyalty would be a great addition to the story.
Often, other Decepticons like Starscream might be involved. Starscream, always vying for power, might see Megatron's condition as an opportunity to finally take over. So he could play a major role in the fanfiction, either causing trouble or having a change of heart. And then there could be some human characters who get caught up in the events, perhaps scientists or soldiers who are trying to understand what's going on with Megatron.
In many 'Stiles is not human fanfiction', Malia could play a significant role. Given her own complex backstory and her were - coyote nature, she might be able to relate to Stiles in some ways if he's not human. She could either help him adapt to his new state or be in conflict with him. Kira could also be involved. Her kitsune powers and her kind nature might lead her to try and understand Stiles. And the Sheriff, Stiles' father, is bound to be in the story. His relationship with Stiles would be put to the test as he discovers his son is not what he thought he was, and he'd have to deal with his own emotions and the potential danger that Stiles' non - human nature could bring.
