I am completely enamored with this character right now. Finally, someone I can unleash my 'dad' kink on~ They are most likely not going to be canon to his character at all, but I'll try to keep some things straight. But I am sticking to the theory that Sans and Papyrus are his kids. Hope y'all like em! :3 Cover art isn't mine!

Hi guys! So this is actually my first time writing a adventure story (and xReader), so I am kind of sorry if it looks crappy!! ****** A long time ago, people were missing when they climb up Mount Ebott. They say there was magic, got lost, or even died. But when you discover the secrets of the mountain, you will get attached to it, and even maybe meet a new 'friend'... ||an W.D. Gaster x Reader fanfic|| •I do NOT own any type of artwork that is included here in the fanfic, all art goes to thier respective owners.•

There was once a scientist who went by the name of Dr. W.D Gaster. He was a great scientist who served under the king of the Underground, until his life was cut short due to an invention he made.
