It's not appropriate at all. Fanfiction should generally be in line with the general tone and target audience of the original work. 'Star vs the Forces of Evil' is not meant to be associated with sexual content. Moreover, writing such fanfiction may cross ethical boundaries and may not be acceptable in the community of fans who respect the original creation.
In a strange world, there was a bathroom that was a battleground between star and evil. The star was a small but powerful entity. The evil in the bathroom took the form of a shadowy figure that lurked in the corners. When the star entered, the evil figure tried to scare it by making the mirror crack. But the star was made of tough stuff. It used its star - power to repair the mirror and then shone its brightest light into the corners. The evil figure hissed and tried to hide, but the star's light was too strong. Eventually, the evil was driven out of the bathroom, and the star made the place a safe and clean space once again.
Firstly, it is a violation of the ethical and moral boundaries associated with the original work. Since 'Star vs the Forces of Evil' is a family - friendly show, this type of fanfiction can mislead younger viewers into thinking that such content is acceptable within the context of the show. Secondly, it can discourage new fans from getting into the show as they may be put off by the existence of such inappropriate fan - made content. Thirdly, it can cause discomfort among the actors and the creative team behind the show who have worked hard to build a positive and family - friendly brand.
Yes, there is a story in 'Star vs the Forces of Evil'. It follows the adventures of Star Butterfly, a magical princess from another dimension. She is sent to Earth to learn how to use her magic better. There, she meets Marco Diaz, and together they face various challenges, including battling the forces of evil that threaten both Earth and Star's home dimension. The story is filled with magic, friendship, and a lot of fun and exciting plot twists.
There could be a fanfiction that puts Evil Star in a situation where she has to face her own good side. Maybe she gets hit by a spell that makes her see the consequences of her evil actions. This could lead to an internal struggle within her, and the story could explore whether she would change or double down on her evil ways. It would be really interesting to see how the writer develops her character in such a scenario.
The story is set in two main places. There's Mewni, which is Star's home dimension. It's a magical place full of strange creatures and kingdoms. And then there's Earth, where Marco lives.
Fanfiction.net is also a good place to look. There are a lot of 'Star vs the Forces of Evil' fanfictions on there. However, the search function might not be as advanced as AO3, but with a bit of digging around, you can find some great Evil Star fanfictions.
One possible moral could be that positive energy (represented by the star) can overcome negative or 'evil' forces, no matter how scary they seem. Just like in the bathroom, where the star faced the evil presence and won through its own brightness and courage.
Another type of fanfic could be about Star's family. It could explore her relationship with her mother and father in different scenarios. For instance, what if her parents had different reactions to her magical growth? Fanfics can offer various interpretations of these family dynamics.
There are many great fanfictions about Star and Marco. Some might focus on their adventures that could have happened off - screen in the show. For example, a fanfiction could explore a parallel universe where they have different powers but still their strong bond remains.
