One popular 'castle oc fanfiction' story could be about an original character (OC) who is a detective in the Castle universe and teams up with Castle and Beckett to solve a mystery. There are also those that focus on the backstory of an OC, like how they got into the world of crime - solving in Castle's world.
The story could focus on a friendship or a budding romance between Akane and the OC. Since Akane has her own personality and responsibilities in Castle Town Dandelion, the OC could either help her with those or introduce her to new ideas. For example, the OC might be from a far - off land and have different ways of doing things. This could lead to interesting interactions and character development for both Akane and the OC.
To make it a good fanfiction, give the OC a unique voice. Don't make them a carbon copy of other characters. For the relationship with Akane, think about how they can support each other. Maybe the OC has a problem that Akane can help with, or vice versa. And finally, proofread your work carefully to eliminate any grammar or spelling mistakes, and make sure the story flows smoothly from one scene to the next.
First, come up with an interesting original character. Decide their personality, backstory, and what makes them unique in the Castle universe. Then, think about a plot that can involve this OC with the existing characters like Castle and Beckett. Maybe start with a simple mystery that your OC can help solve.
Some popular castle fanfiction might include those that explore different romantic scenarios between the main characters. For example, stories that focus on their early days of partnership and how their relationship could have developed differently.
The castle might be a grand and ancient structure. It could have high turrets reaching towards the sky, with thick stone walls that have withstood the test of time. There might be a large moat around it, filled with mysterious creatures. The interior could be filled with secret passages and rooms, just like Hogwarts. There could be a great hall with a long table for feasts and a fireplace that always has a warm fire burning.
Well, it really depends on the specific characters. For example, Castle himself might be flattered by some of the fanfiction that portrays him as an even greater detective or a more charming writer. Beckett, on the other hand, might be a bit more reserved in her reaction. She could be critical of any fanfiction that strays too far from the facts or that misrepresents her in a way she doesn't like. And the other minor characters like Ryan and Esposito might just have a good laugh about it all, enjoying seeing themselves in different fictional scenarios.
One great fanfiction could be one where Beckett discovers Castle's pregnancy and they navigate the challenges together. It might explore how their relationship changes as they prepare for a new addition to their family.
Castle would probably be shocked at first. He'd be thinking 'Why is my daughter doing this?'. Then he'd start trying to talk to her, using his charm and wit to figure out what's going on.
