Well, it really depends on the creativity of the fanfiction authors. In some Twilight fanfiction with 'Caveman Edward', he could be shown as being overly protective in a very primal way. For example, he might be more territorial about Bella, which is different from his more refined character in the original. It can be an interesting exploration of his character if done well.
There are likely some Twilight fanfictions that feature 'Caveman Edward'. This could be a really fun concept as it allows the author to play with the idea of Edward's vampiric nature in a more extreme way. His vampiric instincts, such as his possessiveness and need to protect, could be magnified and presented as more 'caveman - like'. It might also lead to some interesting interactions with other characters, especially Bella, as she has to deal with this more intense version of Edward.
One common theme could be the primal protection of Bella. Edward might act more on his basic instincts to keep her safe.
Well, in some fanfiction, Edward might be tortured by a misunderstanding. For example, if Bella were to believe a false rumor about him and turn against him, that would be a form of torture for him. He's so in love with her that her rejection would be agonizing. Also, there could be a story where Edward is tortured by a new vampire power that he can't control, and it causes him to struggle with his identity and relationships within the Twilight universe.
One interesting fanfiction could be about Edward and Bella's adventures in a different time period. Maybe they end up in the Victorian era and have to navigate their relationship while dealing with the social norms of that time.
One interesting plot idea could be Renesmee growing up and facing the challenges of being a half - vampire in the human world. Maybe she tries to fit in at school but her special abilities keep getting in the way. Another could be Edward's struggle to protect Renesmee from the Volturi while also allowing her to have a normal life. For example, he has to decide how much to shelter her from the vampire world's politics.
One interesting aspect is getting to see the story from Edward's perspective. We can understand his internal struggles with his vampire nature and his love for Bella more deeply. For example, his constant battle between his thirst for blood and his desire to protect Bella.
In some fanfictions, Bella meets Edward in a time - loop scenario. Every day, she has to re - meet him and try to figure out why this is happening. This type of story can explore their relationship from different angles each time they meet, and also add an element of mystery and suspense as Bella tries to break the loop.
There's also 'A Father's Love: Carlisle and Edward'. This fanfic focuses on the deep, father - son bond between them. It shows how Carlisle's unwavering support helps Edward through various challenges in their vampire existence. It has some really heart - warming scenes that show their connection on a different level than just being maker and made.
In Twilight fanfiction, Edward is often depicted as the brooding, vampire hero. He's complex, with his struggle between his love for Bella and his vampire nature. Jacob, on the other hand, is the warm - hearted werewolf. Fanfictions might explore their relationship in different ways. Sometimes they are rivals, fiercely competing for Bella's love. In other stories, they might find a way to coexist or even become friends, despite their natural enmity in the original series.
In the context of fan - created ideas, it can be normal. Fanfiction often explores different aspects of characters that the original work might not have delved into deeply. So, if we consider the world of fan - created scenarios, it's a fun and interesting idea for Edward to read Twilight fanfiction.
In some Twilight fanfiction, Edward might be blamed because of his over - protective nature. He often makes decisions for Bella without fully considering her own desires, which can be seen as controlling and thus draw blame.
