Undertale Gaster and Fallen Child Theory (Spoilers) · 4:44am Dec 27th, 2015
Again, (Spoilers if you've done 100% playthrough of the game)
So we all know about W.D. Gaster, right? Former royal scientist before Alphys, and the the being can only be found when you tampered with the game files. However we have no idea what he is and where he fits into the story. All we know is that his disappearance happened a few years before the start of the game. However, is it possible that Gaster only disappeared sometime after the first child?
