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.)

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?

After breaking the Barrier, Frisk knew there was one soul that needed to be freed, going deep inside himself, he frees the girl trapped in his soul. But instead of thanking him, she tries to kill him! It's up to Frisk and friends to show her Love is not so bad after all (Completed)

"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

Las cosas habían cambiado para ambos. Tras su espada cortarle el brazo, ella supo que no había nada que pudiera hacer para derrotarlo, ni a él ni a ninguno de sus amigos mientras estuvieran juntos. Sus planes se desmoronaron, así que desapareció y nunca más la volvieron a ver, o eso creían todos. Su vínculo nunca podría romperse; porque estaban entrelazados por el destino.

Things changed for both of them. Right after his sword cut her arm off, she knew there was nothing she could do to defeat him, nor anyone as long as they were together. Her plans crumbled, so she vanished, never to be seen again, or so they all thought. Their bond could never be broken; because they were intertwined by Fate. Frisk chased after her, Betty met him each time as well.

Sans tries to use a new strategy to save his world from the being that is trying to wipe out all of monsterkind. This backfires tremendously when a human from the real world (that doesn't even know about Undertale) gets transported into his universe. Will this result in friendship, a game of cat and mouse…or the absolute?

The power of Determination is a strength that humans have in spades. It's what let you journey through the Underground, it's what kept you going in spite of it all. It's what drove you to try and SAVE Asriel... by any and all means. But what happens when that Determination falters? What happens when Determination rots under the weight of what you've done?

A touching story about how a short skeleton, waking up and looking out from his guard post, discovers a warm hat on his head…

His hands wrap around the block of ice, tight but careful. He doesn't want to, can't afford to forget what it's like to hug the queen.

Did I ever mention that her bare arm bore the 8 of vaccination? That I loved her hopelessly? That she was only fourteen? Lolita V. Nabokov Dedication: A character who, in my opinion, is the best in Lolita - a dog. Guf.

The butterfly effect is known as "a property of chaotic systems by which small changes in initial conditions can lead to large-scale and unpredictable variation in the future state of the system." The smallest of changes make the largest of impacts. So… What if when Angel and Frisk fell… they fell into different locations? Squeal "One World, Two Souls", and "One World, Many Souls".

This is a sequel to my old story, Integritale, which you will find in my profile. I don't know if this could be considered an AU to the Undertale Universe, since I did add a lot of stuff, but still tried to adhere to the canon as much as possible. In any case, please, enjoy! Any feedback is welcome!

A Multiverse Phenomenon drags Nightmare to a place that should be unreachable. Yet it changes the course of this Multiverse irrevocably.

"It's only thanks to you that I could change from a sadistic ogre to what I am now. I feel alive for the first time. I can't thank you enough, but I can write down my story." Chara narrates how they accompany Frisk from a Genocide Run to a truly happy ending.
