One common theme is misunderstanding. For instance, they might misinterpret each other's actions or words, leading to the growth of hatred. Another theme could be jealousy. If there is a new character involved, either of them could become jealous and that could turn into hatred.
One fanfic could be 'The Rift between Bella and Edward'. In this, their mutual hatred stems from a misunderstanding about Bella's future plans and Edward's overprotectiveness. Another might be 'Bella and Edward: Enemies at Last' where a new vampire in town creates jealousy and animosity between them.
A common plot could be revenge. If they start hating each other, one or both of them might seek revenge. For instance, Bella could try to expose Edward's vampire secrets to the human world as a way to get back at him. Another plot is competition. They could be competing for something, like a powerful vampire artifact or the love of another character, which makes them rivals and fills them with hatred.
Well, in fanfiction, anything can happen. Maybe a writer decides to explore a different side of their relationship. It could be due to a misunderstanding that spirals out of control. For example, Edward might misinterpret Bella's actions as being self - centered or manipulative, and Bella could see Edward as overbearing and controlling. This would completely change the dynamic from the original love - story in Twilight.
They might tease each other through their words. For example, Edward could use his knowledge of Bella's thoughts (in some fanfics where he still has that ability) to make little remarks that make Bella blush or get flustered.
One way is through the use of humor. For example, they could constantly try to one - up each other in ridiculous ways, like Edward changing all the books in the library to face the wrong way just to annoy Bella who loves order in the library. Another interesting development could be through the introduction of a common enemy. They might be forced to put aside their hatred when a bigger threat, like a new vampire or a bully in school, emerges. They gradually realize that they are not so different after all while fighting this common foe.
In fanfics about Edward and Bella, their love - hate relationship can be complex. Sometimes, the 'hate' might be a misinterpretation due to misunderstandings. For example, Edward's over - protectiveness could be seen as controlling by Bella, leading to some tension that might seem like hate but is actually rooted in their deep love.
In fanfic, the love between Edward and Bella is often idealized. They are seen as soulmates. The 'hate' is then used to add some realism. It could be small things like differences in opinion or actions. For example, if Bella decides to do something risky and Edward opposes it strongly. This creates a bit of 'hate' but in the end, the love always seems to win out as it is the foundation of their relationship in these stories.
No. Fan - created content that involves promoting hate or negative and inappropriate themes like this is not acceptable. It goes against the positive spirit that fan - created works should have and can also be offensive to fans of the original Edward and Bella story.
It could be that a very small number of people have a warped view of the characters. Instead of seeing the love and positive aspects of Edward and Bella's relationship, they want to explore a negative and inappropriate side for some strange or deviant reasons. However, this is not in line with the general perception of the story and its characters.
