Acoording to my research, Dr W.D. Gaster has 2 sons ,the elder is Sans, and the younger is papyrus. I can barely think of how Gaster died/disappear.

1. He fell from the tower in the CORE and shredded in do million, trillion pieces of dust.

2. He sucked into a time machine and started his 'experment'.
