The writing style is crucial. A good fanfic will have smooth and engaging prose. It won't be full of grammar and spelling mistakes. For this pairing specifically, the interactions between the two should be believable.

Also, a bit of humor or emotional depth can really enhance the fanfic.

One main theme is identity. Since it's an underswap, their identities are different from the original, and exploring how they adapt to these new roles is a big part. For example, if Papyrus is more like the original Sans in some aspects, how does he deal with that change.

The clash of personalities. Underswap Papyrus is usually quite positive and energetic, while Underfell Sans has a more edgy and guarded nature. This contrast can lead to really engaging interactions in the fanfictions.
