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
So, the general idea of this fanfic is that Chara never commits suicide and because of it they are still alive when the other humans come to the Underground.
They still hate humanity, but nevertheless aren't willing to commit suicide as they don't wish to leave their family behind, even if that selfishness means Monsters remain trapped in the Underground.
Then four years into their era the second of the eight humans arrives to the Underground, the one who arrived didn't trust Monsters and had in fact come to confirm whether the first human was dead, the fact that they weren't may be the only reason some peaceful resolution can be attained one day...unlikely, however.

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…

Summary
A post‑Pacifist slow‑burn Sans/Reader romance about healing, magic, prejudice and found family.
You work in a bookstore. He’s a skeleton with a soft heart, dangerous magic and a talent for making you laugh, even when the world feels heavy. Papyrus adopts you immediately (and with great enthusiasm).
As monsters struggle to integrate on the surface, you’re pulled into Snowdin’s orbit: political tension, magical injuries, protective brothers, ensemble chaos and a relationship that grows from banter and awkward sweetness into real vulnerability… and eventually, shameless smut.

Summary
"Roman heard the others make noises of agreement and stepped up to their doorway. It had a red frame, as made sense, but despite there not being a door, no light could actually pass through. They stepped in, and the first thing they noticed was the smell of cinnamon. “Oh…” they breathed. It was their mom's house."
Roman and Remus face their regrets and learn that they are not unlovable because of what they did as children.
