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 ;)

The Doorman and The Skeleton by IvyW1nters

Summary
Working as a Doorman is a dangerous enough job as it is, without attracting the attention of a doppelganger. Now it's become a dangerous game, trying to keep the skeleton outside of the apartment building where they can't kill anyone including them. After all, the skeleton is a doppelganger and surely wants the Doorman dead. Especially since they keep stopping him. And yet that look in his eyes doesn't match the murderous intent that other doppelgangers have had in the past. Surely he wants the doorman dead. No other motive or reason, right?

Summary
You have had a tough life that has left you scarred and untrusting of others. Growing up in a mage family obsessed with power and ensuring their lineage, you are the black sheep of the family, possessing a green soul of kindness and excelling in healing and growth rather than the combat magic your family specializes in. Trapped in a loveless relationship with a controlling, abusive partner chosen by your family to ensure a 'proper' match, you live in fear of triggering his anger, often resorting to your magic to heal yourself. Every aspect of your life is controlled by someone else, leaving you resigned to survival and scraping together what happiness you can.
What you could never foresee is the way a miserable night out with your fiance would lead you to a drunken one night stand with your soulmate.
Nor could you predict you would have 9 more soulmates out looking for you.

Summary
On the day of their 13th birthday everyone has a name appear somewhere on their body. A script different than their own, but still familiar and comforting nonetheless. It's said to be your soulmates handwriting and, when you make physical contact for the first time, it's to change to the color of their eyes. Or so the rumor goes. But everyone knows that's just an old wives tale since finding yours is so far and few between.
But then there's you. What the hell are you supposed to do with 12 soulmates?? At least your odds are better than most...

Summary
Sometimes life throws you a curveball. For you, your curveball was going to bed looking like a human, and waking up looking like a monster.
A skeleton monster to be precise.
With the barrier breaking, a large surge of magic descended on the town you live in, and transformed you overnight. Unsure what to do with you, and the others changed, you're ushered into a facility until a monster with similar magic can take you to teach you how to wield the now uncontrollable magic you've been given. After waiting in this place for four years, you'd given up hope that anyone would ever want to take you.
What a surprise for you when you find out that someone does. A lot of someones.

Summary
You should be dead. Everyone else in this god forsaken city died as soon as the barrier came down and these creatures, these MONSTERS, invaded Ebott City. You got lucky, or maybe not.
You had the bloodline of a mage. Which meant you could create barriers. In a moment of panic you had created a barrier in your apartment, locking you and your neighbor inside, and the monsters out.
But now the clock was ticking and you had a group of skeletons sniffing around your apartment, telling you that they couldn’t wait to drag you back to their den.
They meant as food…. r-right?

Summary
A mutation has spread across the globe when monsters were released, humans either dying as their bodies couldn’t handle it or mutated with the rest.
The mutation was simple really, a change of dynamics. Humans started taking more unusual forms, growing more than a few ears, eyes, arms, legs, shit even a head at one point. Or body morphing differently altogether. Turning into their worst nightmares.
Y/N being a young child at the time of the outbreak changed with the rest of her family, half of her family died or killed themselves resulting in her being an Orphan at a young age, left alone in the world as her body shifted and changed. Body becomes leaner, smaller…cute. Cat-like ears and tail sprouting from her body, legs breaking and reforming into back hind legs of a cat's, fur covering her legs stopping at her waist.
Not only that, but she is an Omega.
Of course she doesn’t know oh no no no blissfully unaware, well that is until an over caring human Frisk decides to visit the Orphanage dragging along her friend Chara. Whom in turn absolutely dreads the visit. Let's say…frisk was the door to meeting a rowdy group of skeletons…
