The power to reset the timeline, and the determination to move forward no matter what the cost.

Limits of Determination by Ulrich362 reviews
After getting to the surface countless times Frisk finally decided to tell Sans and Alphys what would inevitably happen, though that's when a desperate plan was suggested. If one soul isn't powerful enough to stop the resets, then maybe three will be. The only question is, how can those three souls meet, and will even that power be enough to stop the endless cycle of resets?

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 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.
