WD Gaster (named after the fonts WINGDINGS and Aster) is a secret character in the RPG UNDERTALE by Toby Fox

Nobody knows much about Gaster, we don't even know what he really looks like, but we know that in the game he was the former royal scientist of the underground

abilities: unknown

Possible appearance: a possibility of what DR Gaster looks like is a goopy noseless Skeleton with a crack going up his right eye and another going down his left eye, he wears a black lab coat and a white sweater, and appears to either have a big hole in both his hands or his hands are closed/ in a fist

it is widely believed that Gaster is the father of sans and papyrus ( the skelebros named after the fonts comic sans and papyrus)
another belief is Gaster created the skelebros by cutting a hole in each of his hands and using what he cut out to clone himself (creating sans and papyrus)
another belief is after Gaster was shattered across space and time he was split into 2 beings therefor meaning sans and papyrus could be 2 halves of Gaster

nobody knows how or why Gaster was erased from his timeline and shattered across space and time

some believe he fell into the core (a giant power converter that converts lava into power that Gaster created)

some say he was pushed in

some say he was sucked into a black hole during one of his many experiments.

W.D. Gaster is a character from the game that made it to the top game lists of 2015, Undertale. This character is very rare and hard to find unless you have a certain software. There have been many theories about W.D Gaster such as him being Sans and Papyrus's dad. There are other theories such as him being Sans and Papyrus mixed together, or being a scientist that created Sans and Papyrus. He is called W.D. Gaster is because he speaks in WingDings (W.D.)
