Summary
A series of dialogue. A set of numbers.
After a slew of countless RESETs, Flowey is driven out of sheer desperation to commit a taboo he has never tried before.
While Papyrus vows to try to help and understand his friend…the truth comes to light when Flowey expresses that he will never feel the same way any other monster can.
Flowey comes up with his own solution for this, and it's not a pleasant one. But apparently that's okay since consequences are usually beyond Flowey.
…But now things are suddenly escalating beyond his control. Not that Papyrus ever had any control to begin with.
Flowey, the Human…is who is in control really the point?
…So then…what's left?
Only the Pretty Poppy can decide now.

Summary
waking up in the body of a skeleton wasn't exactly what you were expecting. the last thing you remember was... the Only thing you remember was a deep, freezing cold (like you would never be warm again), disorienting, blinding, swirling white, and a flash of burning pain. then... nothing. nothing about who you are, who you were. though... the two skeletons in front of you seem familiar, like a memory you can't quite reach. here's hoping you can figure out Something.

Summary
“i’m doctor w-” he cut himself off, reaching up to grab at his jaw. That wasn’t how he spoke. That had never been how he spoke, not in all his years of life. His hands did the speaking where his mouth did not, and it had been that far too long for him to recall whether he couldn’t or merely didn’t. With the sick feeling of magic rising in his trachea, he attempted to sign, hands trembling nearly too hard to form words.

Sans and Papyrus are two halves of a forgotten whole. Sans refuses to let that lost SOUL go.

Summary
After the fall of the Barrier, life on the surface has begun to settle—but not all wounds heal with freedom. Frisk and the monsters navigate the quiet rhythms of a new world while remnants of the Underground’s past ripple beneath their feet. Between sleepless nights and strange seismic readings, old instincts stir, and a journey begins—one that may unearth more than just stone.

Summary
[ It's around seven years since the sixth human fell into the underground. With six human souls captured but no luck in obtaining a seventh, the monsters in the lab decide to start on a new project. ]
OPERATION NEW SOUL
The plan to create a human soul.What if they combined a monster soul with a human one. It seemed silly really, but what could they say, no? So they tried it, They gather fragments of the previous human souls and infuse them with determination.
With half of a monster soul, and half of a human soul—they made…well, a soul. A stable one, maybe? No one really knew.
Some urge immediate use, fearing it will wither like the others. But the lead scientist insisted, “We must wait until its determination is strong enough to break the barrier.”
It seemed foolish. How could a soul, cobbled together in a lab, be strong enough?
Until you’ve opened your eyes.

Summary
(An Underfell illustrated story by ElenArtsy.)
This story is about Frisk's journey through a destroyed and hateful Underground in which they are not welcome. As they struggle to survive the many enemies on their way, they are forced to witness the tragic consequences of the Tyrant's long dictatorship over the citizens' souls and minds... The rules are strict in this merciless world: it's Kill or Be Killed. Will the young human be able to change to fit and survive this cruel reality? Or will they give in to the unstoppable circle of violence?
Based on the comic Underfell by me. (https://www.deviantart.com/elenartsy/art/Underfell-Intro-1-3-A-long-long-time-ago-816753512) You can also read the story and find all of its illustrations on my DeviantArt profile.

Summary
After everything went to black, Clover asked themselfs if this was how death was. If they had anyone to wonder.
It was too dark to see, too silent to hear, too empty to even think about it. A little more and they could feel the cold, hard glass of the container they're inside, trapped for who knows how long. It could be hours, it could be days, or it could be centuries.
It feels like centuries, until it doesn't.
And a dark, misterious ceiling with a light too bright welcomes them. It's not a warm welcome.

Summary
The world choked on war, but for Chara, Kager’s attack was the true devastation. Raiden, her love, didn't just die; his Lumina—his very essence, memories, him—was shattered. Gone. In that void, something cold and sharp awakened within Chara.
Determination. For her, it's not hope; it's power. A RESET. Her one chance to fix this goddamn mess, even if it means tearing reality apart. Love is the raw, constant ache. But HATE, a dark, intoxicating power she's now embracing, will be the edge of her knife. Kager will pay. Raiden will be made whole.
This path is blood and betrayal. She’ll navigate a world of deceit, facing enemies in guises she should trust—even a twisted version of her own damn face from a timeline drowned in LV. Expect gritty magic, brutal fights where survival is the only rule, and the unsettling feeling that any memory could be a breaking point. Or forge her into something worse.
This is Chara's war. Her burden. Her one fractured hope.

Summary
After defeating Asriel in battle for what felt like the thousandth time, something new finally happens. Instead of disappearing, a new magic consumes the human souls and gives them life once again. With the barrier broken, they'll be able to go home and get their own happy endings, right? Unfortunately their families were disturbed by the way they came back to life, and because of the time gaps some felt too old to be parents again.
So where do they go? With the monsters that killed them, to "make amends."

Summary
Was perhaps from the moment that Monsterkind were hurled down Mt Ebott like trash that W.D. Gaster knew humans were rotten creatures? Or maybe it was instead during the war when he had been but a young child. Forced to flee from all he's ever known as battle raged across lands, then later as he grew up to create weapons of mass destruction. Perhaps, it was before he was even born that he had know this truth. Gaster was, after all, one of the smartest monsters to have ever lived, and most certainly was the smartest monster in the Underground.
Because humans were dangerous, after all. They were miserable, miserable creatures that were powerful yes, but miserable.
And his next invention would be the bridge to that gap between their two races. No. Rather then gap it was a chasm.
He would create the first biological weapon, and once the barrier was destroyed then nothing would get in its way.

Summary
The fallen human had had enough of being messed with. Having their body possessed every time they entered the underground was worse than any nightmare. But once they made the choice to fall, falling was always their fate. Perhaps, though, they could change something, just before they lose control...
