Another aspect is the changed relationships. The strong bonds between the Precure characters could be broken or distorted. Friends could turn into enemies, and the trust they once had could be completely shattered.
Create a unique and engaging plot. Don't just have the villains win easily. There should be a complex sequence of events that leads to the bad end. Maybe introduce a new, more powerful villain or a moral dilemma that the Precure can't overcome.
One idea could be an OC who has the power of music in the Precure world. She could use melodies to heal or empower others. Another idea is an OC from a different dimension who comes to the Precure world with unique powers and has to learn how to fit in and fight alongside the Precure. Maybe an OC that is half - human, half - magical creature and has to hide her true identity while being a Precure.
A time - travel plot in a Precure All Stars fanfic could be really cool. Maybe the Precure travel back in time to the origin of their powers and have to make sure that the events that led to their powers being created happen correctly. It could involve meeting their predecessors and learning about the true nature of their powers.
One idea could be to explore a scenario where friends turn on each other due to a misunderstanding over a valuable heirloom. Maybe one friend was entrusted with it for safekeeping but lost it, and the others think it was stolen on purpose.
One idea could be creating an OC who has the power of music in the Precure world. They could use melodies to heal and fight against the villains. Another is an OC from a different dimension who stumbles into the Precure universe and has to learn their ways to help. And also, an OC that is a hybrid of a magical creature and a human in the Precure world, bringing unique powers and a fresh perspective to the story.
One interesting concept could be exploring alternate endings. For example, what if Walter White had managed to escape the law completely and start a new life. Another could be delving deeper into the relationships that weren't fully explored in the show, like the friendship between Jesse and Badger. Fan fictions might also focus on different timelines, such as a pre - Breaking Bad story showing how Walter got into the whole meth - making idea in the first place.
Well, one interesting concept could be the backstories of original characters (OCs). For example, an OC might be a former student of Mr. White who has a vendetta against him for some reason in the fanfiction. Another concept could be OCs that are involved in the drug trade in a different way than the main characters, like they might be trying to expose it from the inside. Also, OCs could be new family members or friends of the main characters that add new dynamics to the story.
A crossover with 'The X - Files' could be really cool. Imagine Mulder and Scully investigating the strange events surrounding the meth production in 'Breaking Bad'. They might suspect some sort of alien influence on the drugs or the people involved, which would add a whole new layer of mystery to the 'Breaking Bad' story.
One interesting concept could be alternative endings for the story. Maybe in some fanfics, Eragon doesn't end up as a Dragon Rider in the same way as in the original. Another could be exploring different relationships between the characters. For example, how Eragon's friendship with Arya might develop in a different direction.
Some Multiversus fanfics explore the backstories of the characters in greater detail. They might expand on why a character has certain abilities or what their life was like before being part of the Multiversus roster. This can add a whole new layer of depth to the characters we already know and love.
