Another theme is the subversion of gender roles. Since Chucky is typically male - associated, having a female version allows for a play on how gender is perceived in horror. For example, a female Chucky might use different tactics to terrify her victims compared to the male one. Also, the theme of motherhood or sisterhood can sometimes be explored in these fanfics, where the female Chucky has a relationship with other characters that is based on these family - like bonds in a very twisted way.
One popular female Chucky fanfic is 'The Girl and Her Doll'. It explores a unique relationship between a young girl and the Chucky doll in a rather spooky and mysterious setting.
One common theme is horror. Given the nature of Chucky and his Bride, the stories are often filled with spooky elements like dark magic and violent scenes.
One idea could be that Andy, now grown up, has to face Chucky again when Chucky resurfaces in a new, more devious form. Maybe Chucky is using modern technology to his advantage, like hacking into security systems to get to Andy.
One common theme could be her struggle with her identity, given her father is Chucky. Another might be her trying to break free from the evil legacy associated with her family.
Well, a big theme is transformation. The female Chucky might start as a menacing figure but then transform into something more positive. Another common theme is isolation. Because of her nature, she may be isolated from others, and the fanfiction explores how she copes with that. And relationships are also a theme. Whether it's her relationship with other Chucky - like figures or with normal humans, it's often explored in these stories.
First, think about the relationship between Chucky and Andy. Are you going to continue the antagonistic relationship from the original? Or are you going to create a new dynamic? Then, come up with a basic plot. It could be as simple as Chucky escaping from a place and Andy trying to stop him.
Their relationship is chaotic. They both love each other in their own deranged way, but they also constantly fight and try to one - up each other. It's a relationship full of power struggles.
The plot could be that the Bride of Chucky is after some powerful jutsu in the Naruto world. She teams up with some of the villains there. Naruto and his friends initially don't understand her powers. As the story progresses, they learn more about her and come up with a plan to defeat her and send her back to her own world.
