What are some interesting plot ideas in bittersweet twilight fanfic?

Well, a possible plot idea for 'a bittersweet potion fanfic' is that the potion is created by an inexperienced wizard. The wizard doesn't realize that the potion has the power to make people experience their greatest fears and joys simultaneously. As the story unfolds, different characters drink the potion accidentally, and we see how they deal with these intense and conflicting emotions. It could also be that the potion was meant for a noble purpose, like curing a plague, but has some bittersweet consequences like changing the appearance of those who take it.

One idea could be to explore the bittersweet relationship between the main characters in a different time period. Maybe they meet in a modern-day setting but still have the same complex emotions as in the original Twilight. Another idea is to focus on the 'bittersweet symphony' aspect more literally, like having music play a crucial role in their relationship, perhaps a song that represents their love and the difficulties they face.

Another plot could revolve around a mystery in Bittersweet Apple Acres. Maybe there are strange happenings in the orchard at night. Is it a supernatural force or just some mischievous animals? The characters could team up to solve this mystery, which would also strengthen their relationships.

One idea could be a story from the perspective of a minor character in the Twilight series, like a werewolf from a different pack who has an encounter with the Cullens. It could explore how they view the vampires and their relationships in Forks.

One idea could be a new vampire character arriving in Forks who has a unique power that disrupts the existing power dynamics between the Cullens and other vampires. For example, this new vampire might be able to manipulate time briefly, which could lead to some really interesting situations like preventing certain events from the original 'Twilight' series from happening or changing the way characters interact.

Another plot could be a time - travel twist. A character accidentally travels back in time and has to navigate the world of Nightfall Twilight in a different era. They might meet younger versions of the main characters and change the future in unexpected ways.

A great plot could involve the inmates of the asylum unknowingly being experimented on by a secret group related to the Twilight lore. They start to develop strange powers or behaviors similar to the supernatural beings in Twilight.

One idea could be exploring the backstories of the characters in more depth. For example, delving into their past relationships, traumas, or what led them to be in the situation during the Emerald Twilight. Another could be a 'what if' scenario, like what if a different character had made a crucial decision during that time. Maybe a fanfic where a minor character steps up and changes the course of events.

One idea could be a story about a new wolf joining the pack and having to prove their worth. Maybe they have a unique ability that the pack initially doubts but later comes to rely on.

A cool plot for a Harry Potter Twilight fanfic could be a competition. The wizards from Harry Potter and the vampires and werewolves from Twilight compete in a series of challenges. These challenges could test both magic and the unique abilities of the Twilight characters. Or perhaps a love triangle between a Harry Potter character, a Twilight vampire, and a Twilight werewolf. It would be interesting to see how the different cultures and powers interact in matters of the heart.
