Summary
A long time ago... humans and monsters lived in harmony. Until war broke between the two races.
The humans were victorious and sealed monsterkind deep underground with a powerful spell, that could only be broken with the power of seven human souls.
This was the tale of Mt. Ebott, and the tale trascended into legend. Those who climbed the mountain, weren't seen again.
And so, begins the tale of the fifth human soul to fall into the land of legend, to fall... into the Underground.
This is the tale of the Purple Soul... Sunny Suzuki.

Summary
The Seven (Plus Chara) have done it; they've ended the imprisonment of all monsters. With Frisk as their ambassador (and Papyrus as mascot), things are sure looking up!
But in the background, things are at play, events that could threaten everyone's happy ending.
After all, just because one story ends it does not mean the Tale has.

Summary
Angel has succeeded in doing what was thought impossible, eliminating the prototype. But at what price, all his friends and toys are dead. So a mysterious entity invites him to return to the past to change the destiny of the Hour of Joy and its consequences.
For those of you who'll be there for the Undertale content, it's there to explain a number of events in the story. The human characters from the Undertale game are mentioned several times in certain chapters, and Frisk begins to appear in chapter 14. If you don't know Poppy Playtime, you can still try reading the fiction and see how the company is responsible for the events in the game.

Summary
“Not so fun being stuck in some loop right? Trying to fight to protect what ya got, not getting a choice in it. If I had the choice I wouldn't remember either.” The words oddly felt comforting. Link let out a slow breath, closing his eyes for a brief moment.
He didn't feel alone for the first time in a long time.
And that?
That was terrifying.
“To be honest, I kinda gave up a while ago. Just sat back and let the chaos go on, felt like nothing I did mattered anymore. Everything would just be reset anyways. Stopped caring what happened, that was until you showed up.” The skeleton’s eyes bore back into the Hylian.

Summary
A tap of fingers on the counter. Sans doesn't react. There's a strange noise, reminiscent of a buzzer, and then a more insistent tap, right next to his auditory canal. Sans doesn't stir.
"Sans Undertale," a strange voice above him says. It's difficult to even call it a voice, it's more so a sound of plastic and metal clicking together, audio distorted as if played back through a broken record. "Don't you know how to greet an old pal? Open your eyes and shake my hand."
Well. He's heard that before.

A Tale of Stars And Time by Pikapuff30
Fandoms: Undertale (Video Game), Deltarune (Video Game), In Stars And Time (Video Game)
12 Dec 2025

Summary
A Tale of Stars And Time is a crossover AU/AT that combines both Undertale and In Stars and Time. Originally inspired by a few memes/fanworks of Siffrin in Undertale, this concept does exactly that – take the characters from ISAT and shove them into Undertale and see whatever the heck happens next.
The general plotline involves Siffrin going through their usual time looping shenanigans in their own world when, mysteriously, a strange grey door appears in a hallway that definitely wasn’t always there. Upon closer inspection, Siffrin and co. are suddenly thrust into the very beginning of the Underground. They are soon met by Frisk, a strange child with more to them than meets the eye. Now, the six of them will journey through the Underground, meeting familiar friends and dangerous foes, with plenty of surprises along the way.
A new play is about to begin, so get on stage, stardust~!

Summary
Sans did not remember his previous name, only that he had been human. Rebirth in Undertale was novel, but he adapted, until he realized that the universe he was in was not the original one.
Unfortunately, it was too late when the machine took him to another universe, into a room full of skeletons.
——————————————————————————————
Sans no recordaba su nombre anterior, solo haber sido un humano. Renacer en Undertale fue una novedad, pero se adaptó, hasta que cayó en cuenta de que el universo en el que estaba no era el original.Lamentablemente, ya era tarde cuando la máquina lo llevo a otro universo en un cuarto lleno de esqueletos.
Nota: Sé que suena como tragedia, pero en realidad es una historia bastante esponjosa de curación, o al menos eso intento. Nuestro protagonista tiene mucho trauma y lo va a sanar en una mansión llena de esqueletos incómodos

Summary
The Multiverse isn't as unreachable as one might think. Sometimes, all it takes is one aware person to tip the scales for another to find out about it. But when one isn't ready for it, returning to their own world is relieving and best for the psyche.
Humanity's thirst for knowledge is near insatiable. How far would they be willing to go to learn more about their new magical coinhabitants on the surface? How far would they go if they could weaponise their magic?

MY ANGEL -ADRIENNE LENKER
Basically the end of the genocide run, but instead of chara being angry or scary, theyre mostly just sad, then frisk comforts them in a silly way because theyre a little kid, then smooches. can be viewed as platonic but (spoiler) chara peppers kisses on frisks face and one on lipsfor my awesome king ALEX ‼️

Summary
Wake up buried in snow, alone, and with no memories?
Check.Keep seeing numbers, words, and random text floating around every object and surface as far as the eye can see?
Also check.Why does every person he meets say he needs help?!
He’s perfectly fine, if you ask him.“I wonder what determination tastes like.”
---
Note from the author:
This is my take on Fatal Error — a much more non-canon,[this isn’t even OOC, this is just straight-up a different person with the same name]
amnesiac version of him.
He’s also not fully canon-compliant in terms of power scaling and may even have a different origin and and backstory.It’s my reimagining of him with a completly diffrent story.

Summary
(A neater, reheated iteration of a work I almost abandoned. Between the 10th Anniversary Undertale stream and Deltarune chapters, I found inspiration to return to it. We'll see how long that lasts.)
You have a new name after burning your old one, and the bridges that led to it. You simply go by Y now, and you are a financial advisor in what used to be a moderately busy tourist hotspot. West Ebbot and Greater Ebbot, a township and city within view of a grand lake and mountain, are husks of their former selves. You know better than to over-confidently think yourself an economic lynchpin, here at your humble banking job, but you do the best you can.
When the polluted lake gets cleaned up, it's too late for the tourism to return. Some years after though, something happens at the mountain that makes it the main attraction instead. The panic of pressure to preform is secondary to the relief of your assuredly continued usefulness, and therefore employment.
Money is necessary for goods and services. It's what society agreed to run on first and foremost, right?
Other sensations are luxuries.
