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.)
