Error's done. Fate has been in control of his life for too long. He doesn't want to do this forced job anymore. No more. So he takes a risk.A risk that eventually makes Error terrified of what's to come. More for the ones he calls family than for himself.
Ink realises he's not the only one suffering from fate. He's just as trapped as Error is in this forced job. So Ink does the best thing he could think of. He helps. Well... That leads to more problems for both of them.
Fate will never go easy on them again.

FGOD Error and Ink are taken by Fate because Error broke the rules, and Ink discovered that Error is experiencing the same struggles as him. The multiverse Sanses must rescue them.

Summary
Welcome to Crossover's Peak Academy! A school used for students from different worlds- Wait, what do you mean we have new students enrolling today?!
Basically, this is a What IF scenario where the UMT cast was brought into an abandoned school building instead of the island, thus leading into different scenarios unlike the original.
This fanfiction is inspired by Danganronpa: Ultimate Meme Team! and Game of Life & Death (Fandom Danganronpa), although it's fine that you don't check either of them. (It's more fun that way)

Summary
Between every Player and every instance of Undertale, standard or AU, is a SOUL. What if that SOUL wasn’t the Player’s? Wasn’t Chara’s, wasn’t Frisk’s? What if it had been plucked from a dying timeline, thought to be inert, and used as our connection?
Featuring a living Chara that’s suspicious of the SOUL they recognize, a living Frisk that’s always willing to give a second chance, a disturbed Sans who remembers memories of a him that in this timeline never was, and a Papyrus who knows more than he lets on.
And a SOUL that vaguely remembers the timeline before it was snatched away. But not what came Before That.

Summary
What if the player never existed?
What if instead of Kris, Noelle fell into that dark fountain with Susie?
What if Kris has no association with the Knight and knows nothing of the dark worlds?
What if the soul that was desperately needed to seal fountains was Kris's and Kris's alone, yet the human is blissfully unaware of how desperately they are needed? Of the leadership fated for them?
...
Kris watched as Noelle walked out of the classroom with Susie, sighing softly.
Whatever. Honestly...they knew they should care more but...Susie never bullied Noelle anyway....
However...for some reason after that, Noelle and Susie completely disappeared for the rest of the fucking day!?!?! And for some goddamn reason when they came back Noelle is randomly seeking them out and Susie is acting weird as fuck, and they're somehow a lot closer??? And for another unknown goddamn reason Susie WILLINGLY asked to do their project.
What the fuck is going on??????
Whatever. They don't need to be a part of this bullshit. At least Berdly is just as confused as to what the hell is going on with their project partners.

Summary
“Pardon?”
“Your native tongue,” Ink repeats. Dream tilts his head, allowing himself to be pulled down into another kiss. It’s quicker this time. Sweet. Sultry. “Talk dirty to me in your native language. You know the trope? You could be telling me you want me to mewl like a cat in heat or that you want me to do your taxes. I wouldn’t be able to tell the difference so it would, uh, take some of the pressure off of you. I…”
“...Just want to hear your voice,” Dream finishes his thought, somehow managing to sound completely free of hubris.
Ink has learned Dream's language. Dream is unaware.

Summary
Every time you close your eyes, you wake up somewhere else — in a world of monsters, magic, and echoes of forgotten kindness.
The Underground welcomes you like a dream that remembers your name. You meet Toriel by her fire, Sans in the snow, and each night feels more real than the waking world you leave behind.
But when morning comes, you vanish.
To them, you fade.
To you, it’s just waking up.Yet the world doesn’t stop when you’re gone.
The cracks in the ruins heal, the snow keeps falling — and the monsters you left behind are starting to wonder why the human who keeps “dreaming” their world always disappears before dawn. -

Summary
You, dear reader, have been transported into your own AU — as Sans.
Just when you’d begun to settle into this new, bone-white life, one small mistake sends everything spiraling.A malfunctioning machine, a flash of blinding light, and suddenly you’re falling through worlds — each one a reflection of stories you once imagined, and others you never dared to write.
Gaster calls it an experiment. Papyrus calls it an accident.
But Sans — your Sans — knows it’s something deeper.Every jump takes you further from home, and closer to the truth behind the tether binding your souls.
Will you find your way back… or lose yourself to the story you created?Whatever happens — the worlds will never be the same now that you are part of them.

You fell.
Which honestly sucks ass.
You had been feeling weird, in your chest, for a while now.
Not sure how you ended up in a world of monsters but you do know one thing.
Your chest is pulling you towards something. And the closer you get, the more whole you feel.
You just hope you don't have to keep dying to get what your SOUL desires.

Summary
Frisk Starling should've been used to cases like these. After all, it was her duty to investigate. Give the victims their voice back, catch the sick freak who did it and give the broken families the justice she couldn’t have for herself.
That is until a string of murders throughout the county begin to appear. Women used like toys, mutilated and disposed of for the cops and journalists to find with only the tiniest slivers of useless evidence and the glaring fact that all the women...
Every…
Single…
One…
Look almost exactly like her… Frisk begins to wonder if maybe… the monster she's hunting down has turned her into the hunted.
And God, does she make the most exhilarating, delicious prey yet…
