"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.

Decidido a vivir como desee, un chico cae accidentalmente por el monte Ebbot, sonde obtiene la capacidad de convertirse en fantasma, habilidad que aprovechara al máximo.

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.

[Horrortale AU] After their fight against Omega Flowey, Frisk left the Underground to get help and save their friends. Unfortunately, humans are not as comprehensive as monterkind and they didn't believe them. How to change their mind ? In the Underground, the situation is getting worse. Toriel and Undyne are fighting for the throne, and chaos is taking place in the Kingdom.

At the end of the war, monsters don't have the choice : they have to join Mont Ebott for survive another day. Sans and Papyrus, forced to run away after the attack of their village, are delivered to the horror of the war without any help and this one objective. But as sons of the royal scientist, W.D Gaster, they are an easy target. Both of them start a dangerous journey.

[Underfell AU] Undyne is weird, and Papyrus doesn't like it. But by the time he tries to understand why, Undyne gives him the lead of the Royal Guard and disappears from his life. But why? Papyrus investigates, as some people try to dissuade him too. Probably because all the tracks are leading to Asgore, and that if he doesn't give up, he might lose way more than his job.

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"

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.)

"My name is Asriel Dreemurr. Six years have passed, and we made it to the Surface. But the world around us is much more dangerous and complex than we initially thought. To reach true reconcilation between Humans and Monsters, we need to help improve the hurt world around us. It will be a difficult struggle for me and my loved ones...but it will all be worth it in the end."

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.

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.)

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.

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?
