"So I was looking up some Sans pictures and found this one au (alternate universe) where Sans turns into a Gaster Blaster sort of like a Werewolf sort of concept. Where W.D Gaster Experiments on Sans and gives him the Gaster Blasters plus makeing him one himself, so I looked more into the au and started to really like it. So I decided to draw a little drawing of Gaster Blaster Sans.....Hope you like >~<"
