Summary
Alexander Koskinen is not a perfect man, but he’s lived his life to what he believes is the best he could. But after falling into the underground, that belief is shattered, and the guilt that has built up over the years has come crashing down, a weight he can no longer bear alone like he has for so long. Now it’s up to Chujin Ketsukane, patriarch of the Ketsukane household, to help pick up the pieces of this lost soul’s life, lest he be consumed by the past that’s been haunting him for all these years.

Summary
My attempt at the "Deltarune Yellow" concept, a world where familiar characters from the beloved fan game are living on the surface with ever so slightly different lives. Given another chance, a failed soul ventures back into the world of Deltarune, but finds itself in unexpected story. How will the prophecy unfold with a new trio of heroes? Will they be strong enough to stop the roaring? Will they live up to the prophecy's demands? Only time will tell.

Clover gets moderately hurt falling into the Dark Ruins. Instead of resetting, Flowey gets the idea to offer his help a little (a lot) more directly than usual.

Summary
Well.
This was new.
Chara was not accustomed to being see-through. After all, being corporeal had been their natural state for most, if not all of their life.
Did that make this non-life or undeath?
They were doubly unaccustomed to seeing another human in the Underground.
Were they dressed as a cowboy????
------------
Basically: Undertale Yellow if NarraChara was still prevalent! What will change? What will stay the same? And WHY is this flower following them around so intently?!Note: This is not connected to a (possible) DND project, it's just connected via being Cocoapowder related.

Summary
(A cross-post of an Undertale Crossover on DeviantART of mine that I'm re-working into a fanfic)
While out on a mission in the Ebott Exclusion Zone to deal with a rogue Mechanloid, Axl finds himself curious about a legend surrounding the place and decides to stay behind to explore after convincing Alia that he'll be careful.
Things go wrong and soon Axl finds himself lost in a world of Monsters and with a strange newfound power. With no way to contact HQ or teleport out, Axl must journey through the Underground on foot. Along the way, meeting new friends and foes while also learning that listening to his trigger finger isn't the only option to solve a dispute.
Will he become the savior that Monsterkind and a group of outcasted Reploids speak of in an ancient prophecy or will he perish like the human children that came before him?

One Step Forward by Electric_Wind

Summary
Everyone deals with grief differently, some ignore it, others can’t find the strength to, and others become numb to themselves after so much of it. This story looks at how the lives of Clover’s friends change in the time after their death, and how they deal with their loss, one step at a time.
Angst and grief won’t be all that’s featured, I hope to balance it with a healthy amount of fluff, character development, and maybe some plot. Figured I should clarify that Clover has They/He pronouns in this fic just to clear up any confusion.

Child Of The Sun by GamerXZ

Summary
Clover had done everything he’d set out to do. He had found out what became of the Fallen Children, helped his new friends resolve their issues, or at least put them on the road to doing so, and now all that was left to do was to finish his journey…and face the destiny that awaited him at the end of the road he had chosen.
But what if, instead of immediately hopping right to giving up his soul, he took the time to stop and weigh all his options? Along with the pros and cons of each? And in doing so, what if he realised there was still one more loose end to tie up? Perhaps even one more soul that needed saving?
It's not like this one deviation from the script will change all that much, right?
….Right?

They don't pass through the barrier as a single entity and die at the hands of humans.Years later, the Underground hones a judgement system for the humans who fall. They are watched, observed, sometimes guided before being taken to King Asgore and having their soul judged. It is their actions that ultimately decide whether they are to live or die. Those that are pure are temporarily free to live out their lives in the Undeground, whereas those who are not...
Their souls are taken for the Barrier. Their bodies are laid to rest in the royal cemetery.Clover is the seventh human to fall down.
Or, UTY Cocoapowder AU where Chara is alive and well and Flowey doesn't have save and reset powers yet.

It Takes A Village by DiamondDeputy (EllaMayLowell)

Summary
All Clover wanted when they entered the Underground was to find the missing children. Instead, they found a legacy of pain and hostility that helps no one. They can’t be sure of what they should want.
All Clover wants now is to live peacefully with their friends, perhaps excluding the one that wanted to kill them. But she’s far from the only one: a human in the Underground is only good for their SOUL. They can’t be sure they’ll ever get what they want.
It only takes seven to free all of monsterkind. But in the meantime, the Royal Guard is on the hunt, Kanako’s status is still a mystery, and Clover’s absence is felt back on the Surface.
(Or: Clover lives AU, and the dynamics and conflicts that follow)

Summary
December 16th, 10:30
Monsters and humans live peacefully on the surface, without any grudges. In the era of progress, monsters completely abandoned magic, as it was no match for new inventions.
This day was very special for one fox - Kanako. As this was her first... trial? That's right, this story will be different from the rest. Here, she will face opponents not in a fight, but in court. Kanako's a defense attorney, trying to find truth and deliver justice to the ones who are really guilty. On her way she will face serious enemies, but she's supported by her mother, Ceroba and "uncle", Starlo. Will she be able to solve the mystery around her father?
This fanfiction is inspired by Ace Attorney games, but don't worry. Cases are designed from scratch (exept for the first one, more details in notes). Also, huge thanks to the whole KanaClover Discord server for advice! (Some ideas for cases were taken from them).
