The contrast in their personalities. Sans is laid - back and often has a sarcastic sense of humor, while Aphmau is more energetic and positive. When they are paired in a fanfic, their interactions can be really fun and unpredictable.
There's a fanfic called 'Sans and Aphmau: An Unlikely Bond'. This one explores how Sans and Aphmau, coming from different universes, form a deep connection. It delves into their emotions and how they support each other through different trials. The writing style is very descriptive, which helps the reader visualize the story better. It also has some unique twists that keep you hooked from start to finish.
One characteristic could be the unique blend of the horror and lust elements from the two 'sans' characters. It might play with the contrast between the spooky or menacing nature of horror sans and the more sensuous or alluring aspects of lust sans.
A popular Ink Sans x Error Sans fanfic is 'Shades of Their World'. In this fanfic, the author does an excellent job of exploring the different aspects of their personalities.

One popular sans x sans fanfic could be those that explore their unique friendship in different AUs (Alternate Universes). For example, some might focus on how they interact during a time of crisis in the Underground.

A 'flowey x sans fanfic' is often a creative work within the Undertale fandom. It might explore unique relationships between Flowey and Sans. These fanfics can range from friendship - based stories to more complex and imaginative scenarios. The authors usually take the distinct personalities of Flowey, the somewhat menacing flower, and Sans, the laid - back skeleton, and blend them in unexpected ways.
Another theme is adventure. Since the original content has elements of adventure, fanfics often include Aphmau and Laurence going on quests together. They might face monsters or solve mysteries, all while their relationship develops. For instance, they could be on a mission to save their village and in the process, their bond gets stronger.
A fanfic I really like is 'Aphmau's Heart and Laurence'. In this one, the writer explores the insecurities that both Aphmau and Laurence have in their relationship. It's not just about the romance but also about how they grow as individuals while being in love. Additionally, 'Laurence's Devotion to Aphmau' is a nice read. It shows Laurence's unwavering dedication to Aphmau through various trials and tribulations that they face in the story.
One of the common themes is also self - discovery. As they interact with each other, both Aphmau and Lucinda often learn more about themselves. For example, Aphmau might discover a new side of herself through Lucinda's influence. And of course, the theme of loyalty pops up a lot. They show loyalty to each other in various situations, whether it's facing an enemy or just dealing with the everyday dramas in their world. This loyalty is what makes their relationship so endearing in these fanfics.
