What are some interesting plot ideas for a Coraline and ParaNorman fanfic?

Maybe a powerful demon that has been lurking in the shadows of both universes. This demon is attracted by the unique magic in both Coraline's and Norman's worlds. It starts to possess the people and creatures in both places, and Coraline and Norman must find a way to exorcise it. The demon could be very cunning, disguising itself as friendly beings at first.

Some interesting ideas for Coraline fanfiction could involve Coraline's relationship with her parents after the events of the movie. Maybe she tries to get them to understand a little bit of the magic she experienced without scaring them. Or you could write about Coraline meeting other children who have had similar experiences with other worlds. This could lead to a whole new adventure as they try to figure out the secrets behind these strange worlds.

An idea could be that the button eyes are a portal to another dimension within the other world. Coraline discovers this accidentally and has to navigate through this new and even stranger place. It would add a new layer of mystery and adventure to the story.

One idea could be a crossover with "Alice in Wonderland". Coraline could fall through a different kind of portal and end up in Wonderland. She could meet the Cheshire Cat and have some interesting conversations about the strange worlds they both come from. Another idea is a crossover with "The Nightmare Before Christmas". Coraline might visit Halloween Town and be both intrigued and a bit scared by the spooky inhabitants.

One idea could be that Norman and Aggie team up to solve a new mystery in Blithe Hollow. Maybe there are strange disappearances that only their combined abilities can figure out. Another plot could be Aggie wants to experience modern life and Norman has to show her around, leading to some comical and heartwarming situations. And they could also face a new supernatural threat that is more powerful than the ones they've encountered before, forcing them to rely on each other more than ever.

One idea could be exploring the backstories of the other cyborgs in more detail. For example, what was their life like before becoming a cyborg? Another could be a time - travel plot where Cyborg 009 goes back to change a crucial event in the past that affected all the cyborgs. Maybe a story about how they interact with normal humans in a world that is starting to accept them more, and the challenges that come with that.

One idea could be a story about a new rookie firefighter joining Station 19. They face challenges in fitting in with the tight - knit team while also dealing with their own personal fears related to the job. For example, they might be afraid of heights but have to overcome it during a high - rise rescue.

One idea could be a story where one of the dalmatian puppies gets lost during a family outing and has to find its way back home by following the scents and memories of the places they've been. It could face various challenges like crossing a busy road or avoiding other unfriendly animals.

One idea could be a mystery in the Catswold where a valuable object is missing and the main character, a cat, has to solve it. Maybe it was a magical collar that gives special powers.

Another plot idea could be a 'what if' scenario. What if the main character in Apathytale made a different choice at a crucial moment? This could lead to a completely different story arc, with new allies and enemies emerging. It could also explore how the relationships between characters change as a result of this one decision.
