Depending on the random "Fun" value your game starts off with, you can encounter some of his followers and even "goner kid". They'll talk a little bit about him and give multiple accounts of what happened to him and why he's out of the timeline.

Goner Kid is a greyed version of Monster Kid - they talk to the PC about what it would be like if someone was removed from the timeline and nobody remembered them.

In his entry for the True Lab, he talks about an experiment regarding photons; this may have to do with light travel. He concludes by saying "What do you two think?" - there's a lot of speculation of who the two are.

sans' one weapon is entitled a gasterblasterin the files. There are also hints of a [REDACTED] (in Wing Dings) encounter tucked into the unused code of Undertale.
