Rodrigo, who just began playing Undertale for the very first time, has to find out which way is best as he ends up in the actual Underground. But when a Fallen Child's soul inhabiting Rodrigo's body tries to drive him to violence, will someone help guide him down the right path? Contains spanking, and minor mention of death, you don't have to read if you don't like that.

Human magic before the Barrier was achieved through the Cooperative Connection, a bond wherein a monster gifts his or her memories, and thus a part of their soul, to a human. Discovered when Queen Toriel gifted a blind prince a blanket which she weaved in her memories of describing the starry sky far above her castle in the Monster Capital.

Cheyenne et sa petite sœur, Neelam, prennent leur indépendance après quinze années passées en famille d'accueil. La plus âgée ne réussissant pas à trouver un travail, Papyrus, leur charmant voisin, lui propose de surveiller son frère, Sans, atteint d'une maladie qui lui fait perdre peu à peu la mémoire. Un travail en apparence facile qui pourrait bien être plus trompeur que prévu.

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.

Thanks to a visit from an alternate Gaster, Frisk now has the power to heal the AUs, but something is trying to stop her. Can she succeed in her quest? Done as a request for dream1990. :)

This is just some fluff with the pairing Charisk (Chara x frisk) Rated T for safety.

Will contain lemon and the like, M rated. After a wet dream, Cherry Red awakes to find herself in the beginning of Undertale! But this time, all the characters are female! But with a very problematic issue involving her being a hermaphrodite, Cherry needs to get through the Underground in one piece... and hopefully not get killed or get fucked in the process. Keep it in your pants!

Littleverse: a multiverse in which most, if not all, of the main characters are children. Small children. Some of which have never had parents to guide them. FMD Ink: a psychopath. What will happen when these two forces meet? Well..a lot of adoption, fluff, and angst, apparently. We do not know how this happened. Go check out Clichély on AO3 and Wattpad!

In which Chara Dreemurr sacrifices herself to save the monsters from extinction.

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"

When Dr. Alphys decides to send letters for her Slumber Party, she couldn't wait for all of her friends to Come! But when she was about to give up... A Certain Fish decides to join the Fun.

A single choice has a huge impact. Not just on one person's life, but on everyone around them. In the Underground, there are many paths one can take. But when Frisk makes a choice that takes them off all the known paths, the world is changed forever, and Frisk becomes intrinsic to the fate of not just Monsters, but the whole world.

Light and dark. Positivity and negativity. The latter keeps swarming, and threatens to consume everything. And only the heroes shining with the light of HOPE may vanquish the assailants, bringing peace and balance back to this world and those surrounding it. The Multiverse is vast and wide, infinite and strange. If peace cannot be achieved... Everything shall perish.

A twist of fate? The path set by destiny? Or some kind of a prank played by the gods? For one reason or another, you've lost everything yet gained so much more. You have the knowledge and the power to change the world, so use it wisely. Follow your heart, seek out the answers and don't forget - you are not alone.

Le créateur ne s'était jamais senti aussi mal, étais ça ? Était-ce le poids à porté pour avoir une âme ? Le destructeur avait des sueurs froides. Pourtant, il n'avait pas peur de grand-chose, et pour cause, il n'avait pas grand-chose à protéger, mais en cet instant, il se sentait sur le point de tout perdre.

Frisk had been pushed into a corner, he was blinded and was chased for a long time, it wasn't supposed to be like this! he was a prodigy that this Era of war needed. Alas, jealousy had killed one of humanity's hopes, Or has it?

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.

You are dropped into the underground world, home to many monsters when a very voluptuous goat mom approaches you and takes you in. There are many mysteries centered around you. It is up to you if you wish to uncover them. This thicc monster lady would like to help, but she wants quite a bit from you. Will you be able to satisfy her overwhelming needs like her husband? Could what yo

(Being Continued) Down into the dark, Chara fell. Down into the dark, an experiment was run. What if she got to go home? But what if it wasn't to the world as she knew it? What if she was placed into another, at another time? What if that happened to be a version of Underfell?

Trois ans après leur sortie des Souterrains, les monstres a été réduit en esclavage. Lysange, professeur documentaliste en école primaire, se retrouve bien malgré elle responsable d'un squelette nommé Papyrus, que l'école s'est procuré pour nettoyer et l'aider à gérer la bibliothèque. Deux mois plus tard, le directeur souhaite le revendre. Mais Lysange peut-elle le laisser partir ?

Gaster and Sans are teaching Papyrus how to use shortcuts, and he's doing extremely well. But when he gets excited and starts thinking about showing his girlfriend, Frisk, what he can now do, things go hilariously wrong. Just a silly little oneshot set in the Hopes, Dreams, And DETERMINATION universe, but it can be read alone.

Once again, the child goes to begin it all again, and finds the universe has had enough. When SAVE and RESET fail, and the earth chooses a new fallen child, a good father gets the chance to be free...and, of course, a sh*t ton of incredibly improbable (and usually traumatic/toothy) things try and stop him. Cover art by yours truly, with credit…obviously.

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.

Just a regular day in the adult lives of Chara and Frisk. A little Charisk slice of life drabble based on a Tumblr prompt.
