One important thing is to stay true to the original characters' personalities. For Frisk, even in an 'abuse' scenario in fanfiction, their core traits like determination should still be somewhat evident. Another aspect is the tone. It should be handled carefully as abuse is a heavy topic. You don't want to glorify it but rather explore how it might affect the character and the story world. Also, make sure the plot makes sense within the Undertale universe.
To make 'undertale abuse frisk fanfiction' engaging yet not overly dark, you could explore Frisk's internal struggle. Instead of just showing the physical or emotional abuse, show how they fight with their own thoughts and beliefs. You can also add some elements of redemption. Maybe the abuser has a change of heart later on. And use vivid descriptions of the Undertale world, like the beautiful yet sometimes eerie landscapes, to draw the readers in and offset the darkness a bit.
However, some might argue that it's a way to explore complex human emotions and relationships in the context of the 'Undertale' universe. But overall, for many, the concept of an abusive relationship involving Frisk is not pleasant and can be quite disturbing.
Some fanfictions focus on the relationship between Frisk and Chara in a more emotional way. For example, Chara might be haunted by their past actions, and Frisk tries to help them come to terms with it. It shows how their bond can be both complex and heart - warming, as they support each other through difficult times.
One interesting fanfiction could be about Sans and Frisk going on an adventure in an alternate Underground. In this story, they might encounter new monsters and have to solve different puzzles together.
There might be some fanfics out there that deal with this concept in an appropriate way. However, it's important to note that such fan - created content may vary greatly in quality and adherence to the original spirit of 'Undertale'. You can start by looking at some well - known 'Undertale' fanfic platforms and filtering through the stories there.
You can try websites like Archive of Our Own (AO3). It has a large collection of Undertale fanfictions, including ones about Sans and Frisk. There are different categories and filters you can use to find exactly what you're looking for.
One common theme could be the power imbalance. Since Frisk has unique powers in the 'Undertale' universe, an abusive relationship might explore how others could misuse that power differential. For example, a character might try to control Frisk's actions using threats related to their powers.
Well, Frisk could be cautious at first. Since Chara in Underswap is different, Frisk might be on guard. However, as they get to know each other, they could become friends. For example, they might share stories about their friends in their respective worlds. Frisk could talk about Sans and Papyrus, while Underswap Chara could talk about their own versions of the characters. Eventually, they could team up to face some challenges in the Underswap world.
Frisk and Chara have a complex relationship already in Undertale. When Error enters the picture, it gets even more interesting. Frisk might be the mediator between Chara and Error. Chara could be hostile towards Error initially, seeing him as a threat to their own existence or plans. Error would likely be dismissive of both of them at first, thinking they are just insignificant parts of a world he might want to destroy.
