Summary
Catti had told Noelle about this blog. One that had started fetishizing the degradation of cervid monsters and made it their kink.
She had resolved to use her following, albeit small, in order to call out these people and get them to stop.
Little did she know, the site's admin was none other than Kris.

Summary
The real world can be a cruel place.
There is no Dark World. No Lightners. No Darkners. No prophecy to set forth a chain of events to whisk away tears and make everything right. No chain of coincidence to magically and miraculously mend broken bonds and build friendships anew.
In the Real World, there is only Kris—lifelong loser and social outcast. Amidst a broken home, an unrequited childhood crush, and the myriad other struggles of adolescence, they want nothing more than to live a regular life—to be normal—to blend in.
Or: Kris weathers the decadence and melodrama of modern suburbia.

Summary
A hundred years after dying, Chara wakes to a world that has already learned how to live without them.
The Dreemurrs, Frisk, and the people around them try to make room anyway. But for Chara, kindness feels unbearable, safety feels stolen, and survival is not the same thing as wanting to stay.

Summary
What if Toriel never left the castle?
What if she faced the issues of her kingdom?
In Undertale, Toriel is introduced as a kind and responsible mother who couldn't bear stay with her husband. Blinded by revenge, Asgore started a war to give hope to their people. Toriel saw this and couldn't bring herself to change his mind.
However, we often overlook just how irresponsible she was at times: abandoning her responsibility and her people instead of confronting her spouse's obsession; leaving a child alone in the Ruins, just hoping they'll stay there; all but forcing a friend into a promise that puts his people in danger and makes him a traitor.
And so, here we'll see how the Underground could've been if its queen kept governing with the king.
Is it better? A bit, but things will be much harder for our human.
No one saved her from Flowey.
No one guided her through the Ruins.
No one asked for a promise.
We'll see all this through the eyes of Aissa, a young girl who won't yield until she finds out all the truth about the monsters that coexisted with humans centuries ago.
(No Toriel bashing!)

Summary
The city of Daiport has many things to brag about. It's ancient history, the beautiful mountain ranges and of course, the glistening ocean beaches that hug a good portion of the city's outskirts.
It's also the home of the monsters that emerged from deep within Mount Ebott.
You, having left your strict family upbringing to chase after your love for the ocean and a dream to become a professional dance choreographer, find yourself in a city quite unlike any other. But life continues much as it always has since you moved here. You work in the local surf shop, train for the biggest dance competition of your life, and spend all of your free time in the water. That is, until a chance encounter leads you to meet a monster who turns up the heat in your life.
As for said monster? He's never met a human with hair as bright as his flames. He finds himself drawn to you for reasons he can't fully understand. So the question you both have to wonder is:
What happens when water and fire collide?

Summary
Hope can be a difficult thing in the face of adversity. Hope can be painful.
For some, it's easier to let go of the pain of what could be different and focus on the wall of pain that is. For others, hope is needed to hold back the landslide behind a fragile wall, so they can keep moving forward and make that hope into the reality they want to see.
A very vague summary to avoid spoilers, because this is a continuation of a large cliffhanger in this series.
**This is NOT a stand-alone fic and can't be read as such! But it does mean there’s plenty more story to read first!**

Summary
I'm just gonna explain a few things about this series.
This story will be a month or 2 after Frisk fell down.
Everyone is still underground. (For now hint hint)
My oc will be a little girl named Charlotte that was hiking with her mother but ended up getting lost and fell into the hole.
Charlotte has long brown hair, red eyes, a scar that goes across their left eye, 5 years old, extremely talented, loves singing and playing intrsuments, survivalist, doesn't show emotions very good, adult like attitude, Empatheitc, helps others when wants too, and only talks when she wants too.
Charlotte's parents aren't the best. (Literally)
Some things may be confusing in the story, but please roll with me! Thank you!
I think that's it for an explanation.
The story will start with Charlotte finding the hole and falling.

Summary
(rewritten)
Trapped in a hostile cold war between humans and monsters, you've been left behind in the city of Ebott, cordoned off as a monster-zone. Too young and too penniless to move away, you and your brother survived mostly on the kindness of Grillby, who gave you a job in secret.
But secrets never stay hidden for long in a city like Ebott. Especially not around a nosy skeleton who's decided not to be lazy for 'human-hunting' any longer.
my take on a darker aftermath of the true ending.

Summary
Certativus: [kɛr.taːˈtiː.weː] In order to stir up strife, combatively.
For years Mt. Ebott has swallowed the sorrow, the mourning, the grief that mankind has gushed. Legends pass through the air, for those that enter, whether that be glory or greed, none return. Children disappear in the depths of night. Forgotten.
They do not remember the trek into the forest, nor the fall that followed it. But, for a mountain supposed to be empty, they are certainly not alone.
