Frisk Launtee, an 18 year old kid from Glasgow, wakes up with newfound powers in a world where fictional characters, from a couple of video games he's played recently, are real. While in this world, his past, present and future will change him as he uncovers the true reasons why he woke up in another world.

A story we're all familiar with, the story of Undertale - only Frisk is replaced with Suction Cup Man.

Knowing a kindness never shown to him before, Vergil walks amongst the Earth as a man, the call to power long since faded. He bears his heart against the veil of Fortuna, their own hearts dimmed. "Show them the impossible, that invisible feeling that cannot be known by mind heart or sight. Show them their souls, show them their sublime." "Bury the light, no more."

Everyone calls Victor's creation a monster, so the creation decides to come to Mount Ebott. (Might end up being a one shot.)

"The heart of man will always be dark. There will always be evil people. The problem is that there is nothing we can humanly do to change them." -Leon Bridges (Sequel to Devil May Fall and Devilish Fortune)

The Underground had seen an incalculable number of resets. Frisk, Sans and Flowey are tired of each reset, but in one reset, two new people fall into the Underground. Will these two break the cycle or will they become a part of it?

The end of the world of war... and the Beginning story of Magnum to rebuilds her homeland, after the World War III... the unexpected thing is... that she wasn't born as a human anymore... (WARNING! THERE'S A LOT OF BAD WORDS! AND ITS NOT A GOOD STORY!)

After completing the 2 main Undertale routes. Lincoln isn’t the same person anymore. As something happens to him that even slightly changes his appearance. How will his sisters react? Will they accept him for having determination powers after being gone for so long?

"This was never meant to happen, you should have just brought them back." Player said as he went to delete her , but then something caught his eye. The Monika lover smiled as he looked at the Heart. "Maybe you can still learn." He moved her file over to UNDERTALE and opened it's files. He was finding a spot to put her, hovering over Frisk's. Then the lightning struck them..

Ruby Rose recognized that person in the tree. They certainly stood out with their disheveled hair, tattered yellow and green shirt and sharp red eyes; yet she couldn't place where she had seen them before. They also had a strange name, and coming from a family with names like theirs that was saying something. Really, who names their child Chara? What kind of color is that?

After leaving BC Freedom Academy because of it's toxicity, Andou had to find a new answer to the troublesome necessity of finding herself a highschool. And what place could be the answer if not ambitious highschool far away south with talented students, questionably powerful leader and new Sensha-do team being created from leftovers? (AU after Das Finale)

How long had it been since she last slept? How long had it been since she went down this path of atonement? How many more of her own self must she bury, before the genocides cease? All she needs to do is look at the stick on her hip, and the LOVE-less Dreemurr knows she can't stop; not now, not ever.

Who knew dying could offer new possibilities to monsters? Or more like a second chance like humans have? Now, it sounds cool if only it wasn't for the fact that I have been transported to Hell... as a Human itself. And why is this other smiler so interested in me? Oh well, at least it's a beautiful day outside.

Frisk succeeded in freeing the Underground from the Barrier, and all is freed back to Tamriel... too much they see is wrecked with strife from the Thalmor, and now a Dragon Menace. Teamed up with Jin, a former Soldier of the Imperial Empire, and the fated Dragonborn, they all travel to stop the Dragon Meance, and the Thalmor in a unlikely alliance. (Pairings Undecided)

/\A Two Kinds x Undertale Crossover/\ On the journey to the Basitin Isles, Trace's voyage is intercepted by a mysterious storm, which was not predicted by Captain Eric's navigator.

"Every year, when the days become shorter and the nights longer, Cats have told stories about the revenge seeking ghost of murderous Cats, who will take you out if your out alone when the moon is at its highest"

What if Frisk was in kny? Will they teach humans and demons to live in peace? Or will she slay them all?

The town called Hometown isn't Papyrus's home. But until he can find his way back to his universe, he'll cheer up the melancholy ghost who sounds like Mettaton. (Papyton AU where Undertale's Papyrus ends up stranded in the Deltarune universe.)
