The TRUE story behind the Fierce Deity. Involves the Tetraforce, OoT, and the Adult timeline.

"Every day I miss you, so every night I howl my heart for every moonlight." #Myquotesarebad

The barrier has been broken for a few years now. Monsters and humans have been living in peace together . . . for the most part. There are rumors about a monster who can somehow change his appearance into a big, scary dragon like skeleton thing. His name is Sans, and as you find out, he's not really that scary, just scared. This is my first ever X Reader, so keep that in mind. Please be kind and if you have any suggestions, let me know! Also, I guess it's kind of a slow burn . . . Art belongs to me. I don't own Gaster Blaster Sans. If you like this story I'm also working on the back story to how Gaster Blaster Sans came to be. It takes place long before this story when W. D. Gaster was still the royal scientist. You can now ask Gaster Blaster Sans: https://www.wattpad.com/story/76026518-ask-gaster-blaster-sans/parts

What is wrong with Sans, and who is Gaster? This is such a reused Description. Undertale belongs to Toby Fox.

*Inspired by werewolf readers x Sans* Your parents had been killed when you were young. Assassination, plain and simple. Thanks to your father, you had inherited the recessive gene he and his father had possessed, making you a vampire, your mother only being a half-fang, having earned a love bite from your dad when they were together. Now 16, you decided to leave the small home you lived in with your now senile grandfather in order to try and explore further points of the world. This led to you falling through a hole in Mt Ebbot onto a bed of flowers, thus starting your adventure in Undertale. Cover by @raindropsandunicorns :D thank ya
