Chara believed themself to be a Demon who should Erase the world. They were wrong. They believed that they could easily move on to the next. They were wrong. They believed that there was nothing in the Void. The Shade Lord plans to show them just how wrong they are. Or... Chara fights The Knight with too many titles.

An AU where the Glitchtale verse and One Punch Man verse are combined. Get ready for an insanely action packed series!

what would happen if sans somehow managed to break the game and a new human had to navigate this broken world?

This fucking sucks PLS dont read it

after the barrier was destroyed all the monsters in the underground were free and happy but for the humans well they weren't happy at all not even in the slightest because as it turns out the only reason why they created the barrier was to not because they hated the monsters but to keep four Pacific creatures trapped inside that's a danger to everything and everyone and now there free

***CLOSED UNTIL FURTHER NOTICE*** Cover photo drawn by SodiePawp. One half of a pic that I commissioned. And what you see here is Chara is tickling MK's feet. ;) Just like my Main Series of Undertale stories, my Side Series of Undertale stories, and my Deltarune Stories/Prompts. Only this time, they're requested by you; the readers! :D Yes, in addition to writing my own personal ideas for stories, I am also open to ideas from fans. So please, feel free to make one or more requests if you'd like. :) But before making a request, please make yourself of aware of the rules listed in the book itself. It's very important that you follow each and every one of them!

For centuries, monsters have been buried beneath the earth, trapped by a magical seal that only seven human souls can break. But the Royal Scientist is tired of waiting for the surface world to fall. To shatter a barrier forged by the strongest human mages in history, he has decided to stop following the rules of the living, and start rewriting the laws of the dead. From a sliver of ancient bone and a vat of concentrated magic, Subject H4Y.D3N is born. He is a ghost of a god-like race, a draconic monster brought back to a world that has forgotten his kind. But life engineered in a cold laboratory comes with a price. As Gaster carves the path for two more "vessels" to follow, he realizes that power is not easily tamed. Toby Fox is the creator of undertale, I only created this AU and Hayden is my creation

Temporary cover, I will be updating it later! This will eventually become a skeleton lodge style fic, maybe papyrusxocxsans haven't fully decided yet Sans was a survivor, he had to be, for both his brothers and the memory of his home, he had to keep carrying on. But this might be his most deadly situation yet. Facing cosmic storms, metiorites, and new excperiences without comunication from earth, can he perservere? AKA: a sans au with some similarities to outertale I think. But with more angst and cosmic horror, hopefully. The other aus wont be joining us until much later, I want to develop this oc's lore first. Spoilers for the storyline below only read if you'd like to know where I plan to take this story. Sans hadn't planned to be the last survivor of earth, he especially didn't plan to get stuck drifting through space without the guidance of his team back on earth with a damaged shuttle and an unknown entity outside, and most of all he didn't expect to get warped through a black hole into an alternate universe. which apparently has happened before if the other skeletons in the lab... basement thing...

Leiko Kamade never meant to become a legend. He doesn't speak-but his soul does. When Leiko falls into the Underground, he expects pain, fear...maybe even death. What he doesn't expect is to fall again-and again-through worlds that should not exist. Silent behind a bamboo muzzle and guided only by mercy, Leiko carries a rare Lilac Soul, a soul of guardianship and quiet strength. He refuses to fight, even in universes where kill or be killed is law. From the familiar warmth of Undertale, to the brutal fury of Underfell, to the role-swapped chaos of Underswap, Leiko walks a path no one else dares to take-one paved with forgiveness, resilience, and love. As monsters hardened by fear begin to change, and powerful beings take notice of his impossible soul, Leiko discovers a truth far more dangerous than any battle: Mercy can reshape worlds. But the multiverse is watching. And not every universe wants to be saved. Lilac Soul is a story of quiet defiance, found family, and a boy who proves that strength does not come from killing-but from choosing kindness, even when it hurts.

I think the title says enough

I died. But I soon found out that I'd been transported to a post-pacifist Undertale timeline. Now as Zen, a goat-like monster. I'll do my best to ensure this world lives on! .... ..... ............. ................. Wrong, something is truly wrong. Terrorist keep attacking. There's something up with Frisk. The most renowned human prophet has gone mad, saying that the world is doomed. The Dreemurs have adopted a new human child named Kris and some of my memories have been erased by a completely unknown being. I needed time to think, so I went for a walk. But then I saw it, a melting black shadow eerily smiling at me only to disappear right after. Seriously, what the f*ck? *Check out my YouTube: https://www.youtube.com/@aDiCaprio6
