Summary
It's really late when you get home from work, only to come face to face with your empty fridge. Barely anything is open at this hour, just a small shop that mostly sells booze, but you'll have to make due.
The cashier is a big, rude, skeleton. Which wouldn't have been a problem if you weren't so tired and hungry, but it really ticks you off. Leaving the store in a fit of rage, your stomach is still growling.
Fine.
You go back to apologise and buy some cheap cookies for dinner. Hopefully that's the last time you'll see his stupid face.
(I've written ahead, hoping to post regularly) -

Summary
After a little accident, Sans ends up with an unreliable connection to the internet on the surface. If anything, it's at least good for a bit of fun.
Or:
You bond with a random guy on the internet who leaves awful puns under your posts.

Summary
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.

An octopus is calling you “Moonbeam”, go figure. by Vin_cant_sea

Summary
Reader is a time-traveler, a universe-hopper, whatever you want to say. They often wake up with a need to explore consuming them, so they do what they do best, go off into random universes and multiverse, and well, fuck around. Problem is: now they’ve caught the eye of a certain God, who looks a bit too much like a slime covered octopus for you to take them seriously. Said octopus has decided that they’ll die before they let you out of sight and is now chasing you through the multiverse.
Basically: You’re a literal chaos incarnation, and you’ve caught Nightmare’s eye. We don’t know if he wants you dead, or if he just wants you—but you fucked around, and now you’ll probably find out.

Alternative Title: I Found Myself In An Isekai Styled Game Of A Game I Barely Know
How’d I get so lost that I found myself in a different dimensional plane?
—
“why is it… every time i see you, your flavor text is always written as ‘confused’.”
“… It’s my default….”
“i find it funny how you sound both confident and confused with just that.”
—
Basically you fell in the middle of the Underground and you just remembered this is a game you played once and never thought about it again. No amount of isekai mangas, reincarnation manhwas, and magical manhuas could ever prepare you for what you should do in situations like these. Because honestly, the fact that you know absolutely nothing outside of playing the neutral route was already a disadvantage.However, you can’t remember if there was an element to the game that included the enslavement of the whole monster race after they got out of the Underground.
Nor can you remember that there was any sort of color to the status windows that keep randomly popping up out of nowhere. Not that you were complaining since these status windows are what keep you alive from this… chaos…

Summary
You’re not sure how you fell into the anti-void but all you want to do is go home. Can you find it in a multiverse of infinite realities? Do you still belong there?
Maybe accepting help from this group of weird skeletons was a bad idea.

The only reason for your own mind hasn’t done such was because you were currently working on a medicine to help the sick borrowers.

By Choice {A Chara x Reader Undertale Fanfic} by imtooshortforyou
Fandoms: Undertale (Video Game)

Summary
Y/N was never the type to be around people. She didn't have many friends besides her sister, but she didn't mind. It wasn't until Frisk and the Dreemurr family came along and became the family she had once lost.
Through Frisk, Y/N is able to realize the power of their determination. One night, as Y/N is hanging out with Frisk and Asriel, the topic of Asriel's dead sibling, Chara, comes up.
For some reason, the conversation led Y/N to want to explore the underground, for maybe there's a lonely ghost wandering around all alone with nobody to talk to.
Reader, Frisk, and Chara use She/They pronouns

But despite the jokes, deep down you were excited at the prospects of an entirely new and fantastical species, plain and simple.
One unlucky day as you're caught in the rain with only a bar to seek refuge in, you get introduced to the monsters within: one of which has definitely caught your eye
