Don't Forget [Sans x Female Reader]
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}

Universe Tale
Remember when Chara killed Sans? What happened if instead of him dying, Gaster pulled him into a different dimension and was able to heal them with a healing pink fountain. Sans doesn't understand how everyone in beach city is okay with him around so he bothers no one and tries to find Gaster. Steven Universe was surprised to see Sans like this, since he visited a memory of Sans being happy and without the red scarf. Will Sans be healed, or broken worse than he already is? Is Papyrus really gone? I don't any of these characters but I do own the plot, enjoy! I will add music.
