What Lies Inside (Gaster!Sans x Reader ) by Jaethefallenhuman

"You know sweetheart, lying doesn't get you anywhere with me." He said lighting a cigarette and placing it in between his teeth. Vanilla, leather, and smoke is quite the intoxicating smell. "I'm not lying, also who gives you the right to judge if I'm lying or not?" Something flickers inside me, a warm burning feeling that fuels my anger with this asshole. Walking up closer to me he pins me against the wall, smoke dances around his skull in a vary of swirls and curves. "Let's get something straight dove, I am your worst nightmare and I am your best daydream. I can see right through people, ironic right? There's something about you, I know you're hiding something inside." He really is good at seeing through people, but the thing is I'm not like anybody else. The media I use in this book does not belong to me, they belong to their rightful owners! Gastersans is NOT my original character ! He was created by Borurou Undertale was created by Toby Fox Highest rankings #1 Gatersansxreader #1 Gastertale #19 Gastersans

Gaster x Reader by MoonReader109

Pretty self explanatory. This takes place after the Pacifist route in Undertale. Through determination, Frisk was able to bring back Chara, Asriel (Asriel is Flowey per say), and Gaster. I believe that Gaster is the father of Sans and Papyrus. I also don't believe that Chara is evil. The monsters are on the surface, and although they are amongst humans, most humans have accepted them.

Underborn by AkiJabarosa

What if Undertale suffered a major glitch? Like you were glitched into the game serious? What if you were able to change the hearts of the citizens of this now twisted world? Which will you choose... Fight or Spare?

[HIATUS] Don't Forget [Sans x Female Reader] by GabrielXander

You would think that with how shit your luck is, you would've been dead day one since falling into the Underground filled with scary monsters and a few spooky skeletons. However, much to your surprise, that did not happen (yet). You know how you ended up here, but you don't know... HOW. You're actually in the GAME Undertale now. And to make matters worse, there are some people who KNOW. You're surviving the best you can, but things are only going to get weirder from here on out. Gaster apparently needs your help? You're using the DJ to go to different AU's? You are gay now?- Okay, maybe that last one is just a joke, but still! You can only hope that your instincts are enough to keep you alive in these trenches. On God, they tryin' to drown you in this hoe! {Available on Patreon, Quotev, and Ao3 under GabrielXander}
