They know they will be missed, but they cannot go back to the living world At least, not for now. Charisk Tales - Part IV (Final)

Undertale characters react to Man on the Internet's Musical. When something more sinister comes to their attention, what will they do? I do not own Undertale or Undertale the Musical.

An Undertale AU, where the Multiverse have created a creature that goes against nature. Read it to know what will happen. (My first story ngl)

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?

The timeline was reset after a Merciless Run. As far as the monsters underground knew, it was just another ordinary day. But beings that no longer existed knew better. The key to either saving or destroying the world in its current state... is Alphys. (Contains elements of the Underswap AU's general concept and the Othertale animation.)

(My own Underfell Take.) A lone human child falls into an underground world out for their blood... and their SOUL. With no friends except for a beaten-up flower, will the child be able to maintain their staunch pacifism? Or will they be forced to accept the motto of their new environment: "Kill or be killed"? (Rated T, just in case.)

Even after the barrier fell and the starved monsters found help and acceptance into the human community, Sans struggles to move on. But maybe things can get better. Even if all you can offer is steadiness and patience. Still, monsters are weird. You can see OC as any gender if you prefer. Kind with perhaps a patient soul. Warnings for panic attacks, PTSD, psychosis, injury.

I left my village to pursue science and magic. I left my village to see a better life than that of my own. I see the cities, I see the new technologies. Cars, lights, electricity. I see it all. And now, just a few weeks into my new life here in this big city, I wake up again living in my objective poverty. Now I must wake up again, to see more of this beautiful world.

Chara gets an uninvited, though not unwelcome, guest.

The barrier is broken. Monsters are free. Take a deep breath, because between securing monster rights, integrating into a new society, and reviving the lost art of magic there's a lot to worry about. Meanwhile Frisk and their ghost friend Chara realize exactly what is needed to revive Asriel: no less than seven human souls, all given willingly. Sequel to How to Save a Soul.

Papyrus, despite common belief, notices things. Especially things pertaining to people. Especially-especially things pertaining to the ups and downs of his brother's well-being... even when Sans would prefer he not notice these things.

What if you didn't destroy the reset button, but rather the menu? How does the world work when you cease to exist? What story will it piece together then? Hateful Glitch explores that question with a new set of characters and enemies alongside some well know past characters who are...A little different. Second Story.

It's been a good many years since Frisk freed the monsters from the underground. She is beginning High School and adjusting to life on the surface with her family. Things are going great until a new kid appears in her class. Arin, a loner, trouble magnet, compulsive liar who doesn't seem to have any friends. What will happen when a dark secret from the past rears its ugly head?

Sans' threat may have not caused any problems with Frisk, but the human in front of him when he makes his threat isn't Frisk. Sans' threat caused a seemingly pacifist to reset into a genocidal timeline.

A human falls into the Underground, and quickly realises that everyone there is either drunk, stoned, or completely off their face. Will they succumb to the temptations of the Underground or stay sober? [Contains a lot of drug use, swearing and graphic depictions of violence] {cover image by u/ipoststupidthings on Reddit)

Chara and Frisk embark on a journey through the underground. The only thing that's different than every other universe where they do this is...

Frisk is hanging out with their family when they accidentally fall through the fabric of the universe and end up somewhere else completely. ...Whoops? Well, at least Azzy's there too. Bittybones!AU! Platonic relationships! Azzy and Frisk are siblings!

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.

After the great Reset, a metanarrative change so violent that it tore the universe apart and recreated it into a completely different narrative.

Time is their enemy, as past events occur an
