Summary
The Multiverse isn't as unreachable as one might think. Sometimes, all it takes is one aware person to tip the scales for another to find out about it. But when one isn't ready for it, returning to their own world is relieving and best for the psyche.
Humanity's thirst for knowledge is near insatiable. How far would they be willing to go to learn more about their new magical coinhabitants on the surface? How far would they go if they could weaponise their magic?

Summary
It wasn't easy bringing the monsters back to the surface.
And against all odds, Frisk managed to do it.

And when an unforeseen surprise causes some new additions to the family, Frisk realizes they might've taken on more than they could handle.

Summary
The strong nuclear force is defined as the strongest of the four fundamental forces of nature. It is the force that binds protons to neutrons inside of an atomic nucleus. On the quantum level, it also binds quarks of similar charge and direction together in order to form protons and neutrons.
The summer after her graduation from undergrad with dual degrees in biotechnology and theoretical physics, the world around Vera Jefferson changed. An entire new race of people poured out of Mt. Ebott, the namesake for her university. The monsters that now populated the militarized zone around the campus and base of the mountain were strange, but kind. Having made quick friends with the sarcastic bartender/owner of the restaurant across the back alley from her apartment, it seemed as though her world had changed for the better.
Once she starts the first semester of her PhD, she realizes just how true that is when she meets some of the other monsters around campus. Life may not be easy, but with the help of the people she went through undergrad with and her new friends from underground, she feels for the first time that she just might make it through.

Summary
“Not so fun being stuck in some loop right? Trying to fight to protect what ya got, not getting a choice in it. If I had the choice I wouldn't remember either.” The words oddly felt comforting. Link let out a slow breath, closing his eyes for a brief moment.
He didn't feel alone for the first time in a long time.
And that?
That was terrifying.
“To be honest, I kinda gave up a while ago. Just sat back and let the chaos go on, felt like nothing I did mattered anymore. Everything would just be reset anyways. Stopped caring what happened, that was until you showed up.” The skeleton’s eyes bore back into the Hylian.

Summary
So I've seen someone else do this and asked myself, why not? I have loads of ideas/situations for fanfics yet have no time to write them or I end up just procrastinating for two years after posting the first chapter (if you're looking at my other fanfic no you aren't). So here goes nothing I guess.
Some will be longer than others, some I might expand on and make multiple chapters, but I don't think I'll make them into full fanfics. Some will have more oc's or more lore/backstory and some won't have any. Some will be about specific skeletons, others will be about all of them. There will be different tropes, jobs and personalities for Reader, and I might make them into a bit of a self-insert sometimes.
Again, if anyone likes any of these, please feel free to use them! But do tell me, mostly to read the end result ;)

Summary
Augmented Human (as opposed to Monster) C4-621 wakes up in the clutches of a notorious new "handler."
... They've experienced way worse than her. And the job she has in mind is probably the cushiest gig they've experienced in quite some time. One might almost call it fun.
Too bad their past is here to catch up with them in a big way.
---------
An unfinished (if long) first chapter for a brainrot induced crossover fic I'll probably never continue. I figured I'd post it here for funsies. Join me in imagining what could have been. I talk about the plans I had in the end notes and second "chapter," where I also show off a little concept art.

Summary
Ever wondered what happened after the true pacifist ending, ever wish you could see all your favourite characters live out their happily ever afters on the surface, want to see what life is like when humans and monsters start living side by side again,
Well, since it seems like a proper sequel to undertale is never gonna happen, I've decided to make my own version that encapsulates everything I loved about the original game and how I think things would play out after the ending,
Hope you enjoy the story.

Summary
Falling into the Underground wasn’t on your to-do list. Falling for two skeletons definitely wasn’t either.
Blue is sunshine bottled in bone—sweet, loud, and determined to make you smile even if it kills him. Rus is quiet, steady, and the kind of person who remembers your favorite tea. Between the two of them, you’re constantly flustered, overfed, and very, very loved.
When both brothers realize they’ve fallen for you, chaos ensues—except it’s the polite, apologetic kind of chaos where no one wants to hurt anyone else. What starts as a tangle of awkward affection becomes something honest and warm: a relationship built on trust, laughter, and a whole lot of skeleton hugs.
“WE CAN SHARE THEM!” Blue insists, bright as ever.
Rus sighs. “That’s not how dating works, bro.” -

Summary
Between set schedules, filming, script readings, proof-editing, dress rehearsals, and his own hang-ups about those star-studded events, Tenna rarely makes a public appearance. This time, though, there was no saying 'no' to the offer of a lifetime: an extravagant, exclusive invitation to an all-expenses-paid gathering of high-profile award winners.
Mettaton and Tenna find themselves in the same limousine, where their first meeting takes a sharp left turn as they find themselves caught dead in the middle of an assassination attempt.
Real drama! Real bloodshed! Real Pippins! Real... Feelings?! Scrap that last part.

Summary
Mettaton is a recluse, and while he does find solace in his cousins, and a couple strangers who knock at his door, he finds the most satisfaction from a television the pair give to him.
The warmth from the screen, the programs he feels like it is purposely showing him, it's weird but... he feels like the TV loves him, in a way that he hasn't been loved before...
He fingers himself to a TV I'm not gonna lie lol
