Summary
One day, or is it night, you wake inside a basement with a familiar skeleton staring down at you in shock. To your surprise, you know him, and the others that live within the complex. Each skeleton has a secret. Including you.
How would they react if they learned they are nothing more than fandom created characters from a beloved game? What would they do if they ever learned you were once a human?

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
It’s fun being dead.
Or undead, rather, as your sister likes to correct you. Your dear sister is the kind of person who took her dark arts very seriously. Or, her necromancy, rather. You’ll be the first to admit, you don’t know a lot about her school of magic. She doesn’t know much about yours either, but it’s always enjoyable to discuss magical theory with her. She says it’s not her specialty, but she tends to under credit herself.

Summary
Nathaniel Walker was an ordinary man who worked as a construction worker to support his elderly parents, but unfortunately met a sudden end during an accident at work. Upon awakening in what he assumed to be limbo, his regrets and attachment to his life keep him from passing on yet unable to go back since no one could undo death. In the end, the void takes his soul and he fades into nothing.
...Only for him to wake up in an underground lab, confused and afraid, while questioning why he's a skeleton... and a child at that.
Nathan has never heard of Undertale, so he's experiencing this world for the first time, unaware that his mere presence has a drastic change on the story you might be familiar with. Regardless, his goal eventually aligns with all of monsterkind, which is to reach the surface so that he may try and find his family again. However he may just find a new family while he's down there.

Summary
Life is a funny thing. Sometimes people grow up and go to school and have a career, some become travelers, and some find solace in a domestic lifestyle. Others are born and then turn into a Monster when they were seven. (Hey. Thats you.)
Monsters were released from the mountain 16 years ago and when they were released, boom! A small percentage of the world turned into monsters overnight. You considered yourself a monster more so than a human. Especially after your mother dropped you off at the facility, and didn't look back. And after all this time, all there is to do is look forward.

Summary
It was cold, so cold, too cold.
You were draining, slowly, as an orange whose juice would be taken....
the warm juice, the warm and red juice. Leaking, through a dam's rift.
You felt like an empty Shell, empty of what it contained, empty, too empty.
You couldn't see anymore, couldn't hear anymore, couldn't feel anymore.
You were surrounded by emptiness. An emptiness that took everything, and nothing at once. Then, Came the light.
and you were no longer… empty.

As a necromancer, you’re used to suspicious stares and whispers of heresy from the townsfolk. It only gets worse after you’re killed and walk Ebott Empire as an undead skeleton. When you hear rumors of a strange settlement that worships the undead, it’s too tempting to resist. The locals treat you better than you’ve ever been treated. That is, right until the moment where you’re dressed up and tied to an altar as a sacrificial bride for their skeleton gods.
Despite their advanced technology and magical prowess, you’re doubtful of their divinity. What kind of gods blush whenever they see a bit of bone?

Summary
This story takes the trope where Monsters have been on the surface for about four, going five years. Then, of course, a skeleton tinkered a bit 𝘵𝘰𝘰 much and brought in several versions of him and his brother. Then not even a year after that, he tinkered with it 𝘢𝘨𝘢𝘪𝘯. But instead of bringing (Y/N) into their world, 𝘵𝘩𝘦𝘺 got transported into 𝘩𝘦𝘳 world.
A world where Humans, some sentient Mobs species 𝘢𝘯𝘥 hybrids roam the many biomes in this strange place. Co-existing not so peacefully; wars tend to happen often, and who's to blame them? Sabotage and betrayal happen, whether it be intentional or unintentional. Nevermind the fact that instincts between species collide with each other. But it helps keep you alive and hey! Most only live thrice!
A story where Reader is a sentient skeleton, is the head chief of a small village, finding out about a jumble of skeletons, goes to skeletons, befriends them, and not so subtly coaxes them into joining her village, and tries to help them get used to her world. Keyword, 𝘵𝘳𝘪𝘦𝘴 𝘵𝘰. Can't these boneheads recognize the 𝘐𝘕𝘛𝘌𝘎𝘙𝘐𝘛𝘠 in her actions? Its not like she's got ulterior motive- or seeking a datemate- well, not yet anyways... Wait what?

This is basically a rewrite of Anti-harem to yandere + obsessive harem.

I'll also be revising and rewriting the smut and other chapters to improve them.

Summary
The world was turned on its head when monsters emerged from Mount. Ebott. Not only because of the whole other civilization that laid forgotten under the mountain, but the magic that was released with them. It didn't just change the world, it changed the people. Literally. Over a third of the world's population turned into monsters, horns and fur and tails sprouting from their skin. The lucky ones were further away from the mountains, their turning being gradual and generally painless.
You were unlucky enough to be in Ebott City when the monsters emerged. Your turning was recorded as one of the worst cases, turning you into a skeleton. The turning was so bad that you had stayed behind in the converted mental hospital for a full year, learning how to cope and adjust to your new form.
You can't stay forever, though, and it was now time to go out, to be released back out into the real world. It was time to get back to it. And you had a very generous house of monsters ready to welcome you in and help you get back onto your feet.
Content/trigger warnings will be at the start of every chapter if they apply.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

At least, that’s what you thought until you were somehow pulled into another universe. Oh, but at least there are a few more skeleton monsters than there were in your last universe! You thought you were the last one. It’s nice to see some new boney faces. It's also a swell opportunity to hang up the ol' coat as a bounty hunter.
It's a little weird that all these new skeletons share names with your former targets though.

Summary
'ALIENS ARE REAL IN ENGLAND', the headline rolling across the bottom edge of the television screen read. the news reporter babbled something unintelligible in their own excitement, before pausing to pivot and look at something off-screen. turning back with a wide grin to face the camera, they hurriedly urged the cameraman to swerve to focus on whatever it was that had caught their interest.
a spaceship, completely and utterly inhuman in design.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
or, in which you are an alien with an appearance strikingly similar to that of a skeleton monster. with a tongue that speaks only in an alien script, you are reluctantly relocated under heavy security to live with monsters that may be able to read your intent rather than the enigmatic language you keep throwing around orally.
━under the condition that they report anything and everything they manage to translate from you to the government.
