A new vampire who is jealous of Edward's relationship with Bella could be the antagonist. With Edward having amnesia, this new vampire could try to take advantage of the situation and win Bella over. They could also try to turn Edward into a more 'evil' version of himself while he is vulnerable.
One idea could be that Edward wakes up with amnesia and forgets his vampire nature. He starts living as a normal human, going to school and making new friends. This would lead to a lot of comical and also heart - wrenching moments as he slowly discovers his true self again.
One popular storyline could be Renesmee's coming - of - age in the vampire world with Edward as her protective father. She might face challenges in school among humans while hiding her true nature, and Edward would be there to guide her through it. Another could be a time - travel scenario where they go back to a significant moment in vampire history and have to deal with the consequences of changing something. There could also be a story where Renesmee discovers a new power and Edward helps her master it while facing opposition from other vampire clans who fear her power.
Sure. Fanfiction writers are very creative. They might come up with all sorts of ideas, like making Edward Cullen be Cedric Diggory. It could be an interesting concept. Maybe they would explore how the traits of Edward from the vampire world of 'Twilight' would combine with Cedric's characteristics in the wizarding world of 'Harry Potter'. It could lead to some unique stories.
Family unity is also a big theme. The Cullen family comes together to support Edward, Bella and the new baby. They all contribute in different ways, like Carlisle with his medical knowledge and Esme with her motherly care, to ensure the well - being of the baby and the family as a whole.
Another could be a cross - over where Hermione stumbles upon Forks while on some sort of international magical research. She meets Edward and they start to exchange knowledge about their different worlds, like Hermione teaching Edward about complex spells and Edward sharing vampire lore.
One example could be a fanfiction where Edward's overprotective nature is exaggerated to the point of annoyance for the other characters, and they constantly call him out on it. For instance, Bella might get fed up with his controlling behavior and start to rebel more strongly than in the original story.
Jealousy is another big theme. His possessive nature makes him easily jealous when other characters get too close to the one he loves. This jealousy then drives a lot of the plot, leading to conflicts and resolutions. In some fanfictions, his jealousy can be quite extreme and lead to some really tense situations.
One great 'Edward Cullen crying' fanfiction is 'The Tear of the Vampire'. It delves deep into his emotional turmoil after Bella's near - death experience. The author does an amazing job of portraying his inner struggle and the way his vampiric nature clashes with his human - like emotions.
