"Long ago, two races ruled over Earth: Humans and Monsters." One race feared for their strong souls, the other for their magic, and the mages caught between them feared for both. All silently knew that war would be inevitable. The only thing that mattered was surviving it. One crimson mage understands that well, and is determined to keep herself and those she cares for alive.

The power to reset the timeline, and the determination to move forward no matter what the cost. These are the two things that keep a young girl moving forward in the mysterious world of the underground. She could be the key to their salvation, but would it all be worth it? Especially if the one person that matters most remains trapped and alone. (I don't own Undertale.)

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?

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.

Sans is putting himself through hell - not knowing that there's someone out there who wants to save him. Based on the Dusttale AU.

Frisk and Eve were supposedly just average kids, living in a world where the human monster war never happened. However, when they find out about alternate universe, it is a literal race against time, to save not just their world, but others too.

With a quick use of Sans' magic, we had returned to our home on the surface. The lovely three-story home sat quietly among the trees under the moonlight. Sans always loved to teleport just outside the door and glance at it before walking in. He was a little less lazy since coming to the surface. So much to learn. So much to do. So much to love. SEQUEL TO "TWO WORLDS, TWO SOULS"

One of twenty-one - A young man named Carter - was pulled into Undertale under the command of different W.D. Gasters. When he comes across a Genocidal human, he has only one path laid before him - Fight, or die. (Spinoff of XWolf26's Doubletale. Final time I'm rewriting this one, I promise.)

After thousands of resets, Frisk succeeded in doing what everyone, including Sans, thought impossible: bringing back the lost prince and destroying the loop that was causing them so much suffering. Two years later, now an ambassador, he seeks to restore human-monster relation, while fighting against an evil that seems to be spreading in Ebott and threatening his new family.

A "shortcut" gone wrong results in Sans and Papyrus swapping bodies. But the greatest scientific breakthroughs often start as accidents—and this might be the key Alphys needs to save Chara and Flowey. (Includes Soriel, Papyton, and Alphyne as ships. Crossposted from AO3)

"The little girl just could not sleep because her thoughts were way too deep, her mind had gone out for a stroll and fallen down the rabbit hole." - A life of fear is not what Frisk ever expected to have. - Warning: this is a dark AU that tackles mature themes and is not recommended for sensitive readers.

What if the war never happened the way it did; Monsters enforced a peace back into the land after and now many years later, things take place in a new stadium, in a new life. Frisk in the care of a very motherly Monster, Asriel dealing with his father's new less than legal business, All the while juggling an offer he is to give.

Six years later, things have changed, but evil still lives. Chara's determination for revenge against the cruel world drives her to return. Frisk now must do what she can to protect her people from humanity's twisted views of monsters and avoid becoming the host for Chara's revenge

"El jugador" ha muerto... Y ahora todos quieren JUGAR. En la peligrosa Ebott City, radica una constante inconformidad por habitar monstruos y humanos en un mismo lugar., desatándose conflictos delictivos que atentan con la vida de los habitantes. Sin importarle las advertencias de su madre, Frisk decide ir a la ciudad y tener su florería junto con su compañero y mejor amigo Flowey

Everything has a story. And sometimes, those Stories don't start like you expect Part of We All have Stories Series, Cross posted wattpad and Ao3

Frisk is a 18 year-old young man who just graduated high school. He arranges a hiking trip with his best friend Jack, which leads to him falling in a mysterious hole. Can Frisk survive the monster realm?

HELLO! PLEASE READ! Just give it a... chance... I'm sorry lol. (if you wanna. Also sorry its a foo foo cover, I'll make it cooler when I have the time.) Things may seem fine now, but what will you do when all hope is lost? When there's only the slimest of chances. All across different AU's some of our beloved characters are becoming aware of a new and threatening presence.

If she could go back in time she would grab that USB, jam it into her computer and download that stupid game. To hell with exams and getting into uni. This was a matter of life and death. From before the war to its aftermath and the game.

Recordar el pasado debería tratarse de risas, nostalgia y alegría, algunas veces tristeza. Al menos eso es lo que Asriel Dreemurr solía creer, antes de que su hermana terminase perturbándole hasta lo más profundo de su ser. Para Chara, su hermano se está volviendo loco, y quizás tiene razón. Pero cuando no puedes confiar en tus propios recuerdos... ¿entonces en quién?

Reminiscing about the past should always be about laughs, nostalgia and joy, sometimes sadness. Atleast, that's what Asriel Dreemurr used to think, before his sister ended up shaking him to his core. To Chara, her brother is going insane. Perhaps it's the truth... but when you can't trust your own memories, then who can you trust?

The Riverperson is a very mysterious person in the Underground. Letting Frisk ride in their boat wherever they need it. They are always so carefree, but what if there is more underneath the surface.

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.

Frisk woke up. What had happened? They soon found out they were not in control of their body. More to their dismay, the one controlling them wasn't a very merciful person. If Frisk doesn't get control back, who knew what would happen to the Underground? They would soon find out…

No one messes with his family. Not even a homicidal 12-year-old who can't talk.

What if two humans were in the Underground at once? What if one human was DETERMINED to stop the other? What if they could both SAVE? What happens when an Unstoppable Force meets an Immovable Object? When a certain scientist pulls enough of himself together, he finally finds a way to stop the destruction of his world. (Undertale AU. Rewrite of DT.)
