Underverse Stories

Underverse self insert Includes Y/N's that might actually make sense REWRITE

Born in a void, devoid of all life, Glitch Gaster had nothing. He had to watch as other Au's got to experience lives and outcomes.. While he had nothing. He loathed to have what they had. One day, Glitch Gaster witnessed the power of 'OverWrite'. He became obsessed with the idea of true power.. The idea of becoming so strong nobody could oppose him. He wanted a world of his own.. But not just that. He wanted more.. MORE POWER. He wanted to become god of a world. So with Inks help, Glitch Gaster created his own masterpiece.. the 'Glitch' button. Using it, he created a world of his design. A fake world.. With nothing real in it. All to be his plaything.. To satisfy his hunger for more power. But not everything goes how you want it to.. One of his creations suffers a malfunction. A glitch in the code.. And suddenly. He can feel, see, hear.. He's.. Real? But with a power hungry god ruling over his world, can newfound sentience really overpower raw strength when your whole life has been a lie?

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.

{Sequel to "Can I Have a Say?"} {Credit to the amazing artist!} Killer got what he wanted. He's free from the spell Nightmare had him under, but now he's even deeper. Nightmare still controls him, so Killer isn't sure anything even changed. But this time, Killer isn't the only one that needs help. Cross has something that he decides to admit as well that makes his deal to Nightmare far deeper than it was before. The two must get Dreams help when everyone else is against them if they want to finally be free. {POV: I actually updated this. - 3/6/22}

Btw cover is my old art so it's surprisingly slay. (This is the first book I've ever written so the start is sucky and has spelling mistakes) I haven't updated this in like a year, I'm currently rewriting this so I promise when it comes out it will be better then this version, thank my previous English teacher for teaching me how to write correctly. ⚠Needs editing⚠ Error and Ink may be enemy's, and polar opposites, but they are both more alike than they think. After being attacked by an unidentified enemy, both Ink and Error are badly injured. Once the enemy disappears without a trace, neither Ink nor error can seem to teleport or create a portal out of the anti-void. They now have to work together and find get help in order to get out. From both sides in and out of the anti void everyone must help and research to get ink and error out. Will they find a way out? If so, what happens once they do? Will a truce become permanent? I remember people saying that Blueberry and Swap aren't the same person. But they're actually two different versions of the same character from Swaptale. So initially interpret my Swap sans as whichever design as you want. But the personality is supposed to be of swaps design. I'm just calling him blue. !! TW, this does include the gay and ErrorInk so this might not be for u. This will also includes mild course languages from time to time and mentions of blood!! Ships: Errink (Error x Ink) (There may be more added on later in the story)

This story is about a guardian named Dream, who has a terrible disorder named Tekanus, which can make him cannibalistic if starved for a long time. It occurred during his creation due to a magical imbalance and heavy loss of Nim's blood. Therefore, Nim thought of him as a mistake and neglected him and cared for Nightmare, who cared for Dream. Time flies by, after the Apple Incident, as usual, Nightmare became corrupted while Dream turned to stone. After 495 years, Dream goes berserk due to starvation after a long time but is later calmed down by his brother. He now moves on but keeps his disorder as a secret but is later exposed when Ink Sans starves him for a long time and mocks him for not saving his girlfriend, her sister and his brother.

No. Something's wrong. Why is Dream feeling and absorbing negativity? This is a Sans AU that I randomly came up with at 12am one night. Dream Sans is basically like Dust/Murder Sans, and teams with Nightmare against Ink 'cause Ink's being Ink. Yeah. That's...Really basically it. Enjoy! Or don't. Doesn't change my life. [ Cover Art does not belong to me!! ]

Rurik Liderc, the once feared general who led a division of Asgore's army, now faces the greatest challenge of all: losing the final individual who stuck around through everything. In a timeline in which the toxicity between these two people went unchecked, what dire consequences came as a result? How does a monster really become monstrous? What factors push a man to his breaking point and beyond? And is there anything which can be done about it? I originally wanted this out in October, but I kept changing storylines. Better late than never, I guess! This will be my first attempt at a paced-out, multi-arc story. I want to sincerely thank anybody who has seen my one-shot book, whether it was just to read, leave a favorite, or even a comment. I never thought it would've gained the attention it did and has encouraged me to try different feats of writing. I also want to thank my incredible role play partner, Jade, for a couple of the ideas utilized in this tale. Updates every Sunday.

Christine is banished to darktale (here live all the evil sanses like horror, dust, swapfell, nightmare and cross) for killing the kings and queens of 25 diffrent universes. 'It wasn't me it was the demon inside me (Crystal) the last part of the shadow Phoenix soul'. For years she lived with the demon inside her. Will it ever be possible for her to be free from the shadow or will she'll always be the Shadow Phoenix Keeper?

Dust, Horror and Killer have been friends for as long as they could remember. They wouldn't do any missions correctly unless the three of them were together. All of a sudden, the three of them notice that the feel different around each other. ships included errormare cross x epic dream x ink x blue after death ------‐--------------------------- enjoy! other stories may not include the same ships DISCLAIMER!!!!! none of these characters are mine and all belong to their respectful owners.

Infected has somehow returned from the dead! As he sends viruses out to destroy all AU's everything is affected by his malicious hate and termination and is engulfed in peril. Various Sans's join together to stop this madness from becoming unstoppable. However due to Error falling ill to an unknown sickness,- will they be able to save the multiverse? Or will they have to show infected 404 reasons to fight. ( OC Cover art by me) Error404 and Infected characters belong to; Shadikal15 Cyan!Sans and his different forms (Geno!Cyan, Paci!Cyan, Neutral!Cyan etc.) belong to; Kagami-Shinami Error!Sans belongs to; LoverofPiggies (More credits will be at the end of the book. I can guarantee you that this book will be more than fifty chapters long.) Change-log is edited about every day, new updates are below the old ones.

As classic sans was just minding his own, the different versions of him that he never even knew about brought him into a war he wished that he slept off. All of the multiverses are colliding and collapsing as the sanses clash for survival.
