After getting through the entirety of Undertale and Undertale Yellow, the latter being able to be beaten on every route, Scarlet Johnson wakes up from a slumber to find himself in the body of Frisk and being joined by Chara. And after learning he's in the Undertale universe, but with nods to Undertale Yellow, he needs to get through or die trying. T rated for language and innuendo.

After doing everything the right way in the first timeline, Frisk was compelled to do the genocide route for what they felt were "good" reasons. In doing so, they have broken utterly and become something new. Something absolutely devoted to Sans, and not remotely sane. Now they are striving to fix everything and find their path forward. What the hell is Sans supposed to do now?

Luna ends up in the Underswap universe. Done as a request for paradise dazzleshine. :)

just a few one shots for my OC of ErrorSans, Sol Reapa. one of the few known as a traveler. that means Sol can move though the void between multiverses. I have expanded this to an ability to move around the entire multiverse, regulating undertale AU multiverses to a 'pocket verse'. this way it is easy for him to go to other fandoms. so large crossovers will happen.

The world is destroyed. Strange creatures no one has seen before have swarmed the planet, killing everything save a small band of Monsters, and soon, even they will be gone. Their only hope, a thousand years in the past. Traveling back to the war of humans and Monsters, Frisk and their friends hope to change the outcome of the war to avert this horrible future.

Does not contain the word 'f-ck'. (sh!tpost)

According to all known laws of aviation, a bee shouldn't be able to fly... (sh!tpost)

You know, being dead for a couple of centuries gives you time to think. About your choices. About those you hurt. And for me, it gives me the opportunity to mourn and fester in the guilt of being unable to save the ones you love.

And ends the world. (sh!tpost)

Basically a literary port of a YouTube video, which itself is a parody of the SLACKICiRCUS techno cover of the song by the 4 Non Blondes. Papyrus accidentally absorbs Frisk's soul, and, now bursting with DETERMINATION, grows fabulous hair and cannot hold his urge to SING! (sh!tpost)

Obvious spoilers. My thoughts on Undertale. (sh!tpost)

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.

Years pass. People grow. The world moves on without you. However, through the threads of time, a connection is established.

However, four years after the monsters are freed, time reloads by a few hours.

This is a self insert undertale yellow fic, but since undertale yellow wasn’t a category I just put undertale
