Sans

Sans is a character from Undertale who frequently cameos in the Dorws CYOA, but yet to appear in person. He's one of senok's defining characters, which justifies his random, out of place appearances. He can be a picture on the wall, a doll in a bedroom, or a strange cloud that looks suspiciously like him.

Several characters appear as different versions of Sans, such as Epic Sands and Arms and Head Sans. No explained reason for these malformed clones exists, they simply are there.

Cameo Appearances

 * The Sans Cloud often appears in the background, along with many other symbolic clouds. In nighttime, it's replaced by the Sans Constellation.
 * The Mysterious Room has a doll of Sans on the table.
 * In Bakseet, there's a whole golden statue of him, and it's stated that he's a major figure there, and that many of the residents looks similar to him, which the backgrounds can occasionally reflect.
 * Undertown is entirely dedicated to Sans-es who thought they were above Bakseet. The background is completely full of Sans variants, as well as the known residents.
