Mistakes were made, but by Rhythm-is-best-pony reviews
They have known each other for a long time. They fought often, they each lost and won an equal amount of times. It was a routine of theirs. Destroying Alternate Universe, fixing them, destroy, fix, again and again. There seems to be no stop. No one would dare get in their way, no one dared to help nor did any others tried to reason with them. And this story is no exceptions...

Under Tail by F14M3RZ reviews
Life is weird, but at the end of the day, we've gotta keep moving forward and all that. Join this unnamed protagonist as they traverse through a familiar land encompassing an unfamiliar sin. Hilarity, tragedy, gijinka/anthro (humanized), and various pop culture references will ensue. Rated M for lemons, language, and puns. Adopted from the OG theirself, Mushroomstoryperson.

My Undertale by Abyssal Angel
This story is not for general consumption. It's not even really a story. Not truly. It's more a stream of conscience in the form of a story that I needed to get out of my head so it would stop bothering me. So if I'm posting this for anyone, I'm posting it for me. It's not a happy story. Feel free to give it a miss.DISCLAIMER: If you recognize it, I don't own it. I only own myself.

Skeletons and self harm by MNLMFangirl
Rated T for self harm and such things. Meant to be more of a comfort story with more chapters in progress. The skeletons find out that the reader is harming themselves and they want to help the reader with this. In their own ways though all with the same goal to help out the reader who they care about so much. Too much to let them be hurting even if they are doing it to themselves.

The Golden Quiche by Sophtopus reviews
For Monsterkind, the Surface represented freedom. For Frisk, it's a return to some uncomfortable realities. It all began with a simple wish. When that wish faded, Frisk tried to move on. Except, 'moving on' was not so simple. Emerging from the Underground had put them in a worldwide spotlight. From an unknown child, they had become an icon of great value.

The Purest Soul by CornOnTheJob
A prophecy, whispered between darkness. A child, born of light and shadow. A promise, given only to men and beast. A war, breaking them apart. A perniciousness, resulting from the taint of an Angel. Scores of tragedy and pain. A story of many lines, many events. A cursed catalyst to unite them all. Frisk's rise to power fails.

Growthspurt by IrishPlagueDoctor reviews
It's just another late night for Gaster. Not something he's fond of doing, but at least his oldest is old enough to care for his youngest. But when the Royal Scientist finally enters Snowdin, everything is closed, all the lights are off-as it should, for the ungodly hour Gaster was arriving in-but all the lights in his house were still on. Something wasn't right. GB AU
