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
Monsterkind is finally free. Everyone is at the surface now. A happy ending is it not? To the little cowpoke’s surprise he is alive again! And it seems he was not the only one that was brought back to life.
Clover may not know why he’s alive again but one thing for sure is that going on another adventure wouldn’t hurt him at all, it’s time for him to bring Justice once again. Meanwhile the darkness seems to grow darker, yet darker.

Summary
This the story of Kingdomtale, an au I created that's essentially Undertale if it took place in the medieval century. It's not historically accurate but it's my take on this popular concept. I have already posted a series for this au but have grown dissatisfied with it. I know I can write something better. This is the new and improved Kingdomtale, and it's going to come back even stronger and better than before. My hope is that this story can feel nostalgic in a way, like you are experiencing Undertale all over again for the first time.
Here is just a quick snippet of the plot: The year is 15XX, and another human has fallen down Mount Ebott. This human is no more than a child, having woken up in a bed of golden flowers. How did they get there? They'll soon discover a world of monsters, magic, and much more. Can one human child bring peace between two different races that have been forced to share one Kingdom? Well, you'll just have to read to see if the story is still as you remember it.

Without History (maybe some things should stay forgotten) by Human_with_no_life
Fandoms: Undertale (Video Game)
15 Dec 2025
Tags
Summary
After the barrier breaks, Monsters and Humans have learnt to live together on the surface, there is still many mysteries hidden in the underground. Most of them will stay forgotten or buried forever.
Until a ‘promise’ Sans made with Frisk leads to him telling a long and complicated story. His story, well not exactly 'his', but with as many questions as it answers, it seems to raise more. One thing is for sure; this tale will change everything.

Summary
After the events of the true pacifist route in Undertale Red & Yellow (with Frisk choosing to stay with Toriel):
Monsterkind has been living peacefully on the surface among humans ever since a young child, Frisk, saved them from their long captivity in the underground.
All is well for Frisk and their friends. All except Clover, a young boy who was recently brought back to life by Asriel Dreemurr as gift for his selfless sacrifice in the underground. While he appreciates his second chance at life, he has never gotten over a friend he wishes he had never had to say goodbye to. Chara Dreemurr, the first human to fall into the underground, and one of two ghosts, alongside Clover, who guided Frisk through their journey, has not forgotten about her friend either. Unlike Clover, Chara was not given a second chance at life, and continues to watch over Frisk on the surface. While she enjoys Frisk’s company, Clover has always been at the forefront of her mind. Unknowingly to Clover, there is one way for Chara to return to the living realm. However, Chara has been hesitant to act on this.
After all, such an act would require a permanent marriage of souls.

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
The barrier was shattered and monsterkind finally got their freedom, but what of the humans that came before?
They deserve a happy ending too.
But with so little power left remaining after destroying the barrier, a half-measure would have to be taken.
Better than nothing, right? And for some of them, much more preferable to how they were before and certainly during their deaths.
The Sixth and final SOUL is the last to awaken, and by that point, things have been quiet in the Underground for quite a while.
But there is still one more thing to be done, one more person to save, and in many ways they're tied to that Sixth SOUL as well as the Underground's self proclaimed caretaker.
A second chance and a happier life awaits Clover and Kanako if they can just grasp it.
