    !(Undertale as well as Deltarune was made by Toby Fox, while Glitchtale is an AU made by Camila Cuevas, only my OC is added to the stories. An AU. Male OC x UT, GT, DR) Long ago, two races ruled the world. HUMANS. and MONSTERS. They lived beneath the same sky, until war tore that world apart. Humanity emerged victorious. The monsters were sealed beneath the earth. And the world forgot them. But beneath the surface, another legend survived. A legend of LIGHT. A legend of DARK. A legend of DREAMS. And a legend of HOPE. For millennia, Light and Dark existed apart. Yet neither could exist forever without the other. And when their balance finally began to fracture... The world began to remember. The forgotten. The fallen. The souls that refused to disappear. And somewhere between Light and Dark... One soul awakened. A soul unlike the others. Not born from Determination Not born from Fear. But from something far more fragile. HOPE.

    After witnessing countless Genocide Routes across endless timelines, Sans finally breaks. Convinced that humanity is beyond redemption, he abandons everything he once stood for. By embracing LOVE and accumulating EXP, Sans transforms himself into the very monster he once warned others about. After reaching LV 20, he exterminates the entire Underground, defeats Omega Flowey to end the possibility of Resets, and wins a cataclysmic final battle against a Determination-fueled Frisk-a battle so devastating that it ends with the destruction of the Solar System. Believing he has finally erased humanity forever, Sans dies in peace. ...Only to awaken in Hell. Instead of eternal punishment, he finds a city overflowing with laughter, greed, violence, and indulgence. Humanity still exists as Sinners, seemingly free from the consequences of their actions. To Sans, Hell has failed its one purpose. If Hell won't judge humanity... He will. Armed with soul-destroying magic capable of permanently erasing Sinners, Sans begins a ruthless crusade through Pentagram City, becoming one of the most feared beings in Hell. While Princess Charlie Morningstar fights to redeem lost souls, Sans believes redemption is nothing more than a lie told to monsters and sinners alike. As mysterious disappearances spread across the Pride Ring and powerful Overlords begin vanishing without a trace, Charlie and the Hazbin Hotel are forced to confront a terrifying truth: This isn't just another Sinner. This is a broken judge from another universe who has declared war on humanity itself. Caught between redemption and retribution, hope and hatred, Charlie must find a way to save the one soul who no longer believes anyone deserves saving... before his twisted sense of justice plunges all of Hell into chaos. Because everyone gets judged... And in Hell, Sans has become the judge, jury, and executioner.

    The barrier is broken, freeing monsters from the Underground to the Surface... Only the Surface isn't as Frisk remembers. Apparently, heroes are taking the stage now, Earth's most mightiest and most dangerous. Sans is being flagged as one for his immense well of magic power. How will this ragtag team that can barely hold themselves together do when you throw a lazy, pun loving skeleton into the mix?

    [Cover belongs to me] Error is the (forced) god of destruction, Ink is the god of creation. Both are needed to keep the balance, but while one is loved the other is hated. Ink together with the judges elaborated a plan to finally stop Error. A deadly trap. Impossible to escape even for the feared destroyer. But someone is not following the plan. Things get out of control. Error gets out of control. Although things don't go exactly as planed, and the results are more chaotic than they should. It still worked. Error was finally gone. Lost into the VOID, scattering across time and space. But someone had their eyes on the broken destroyer for a long time, and they were waiting for this moment. Now they can finally act. And take care of their chosen child. ... Error woke up at the sound of his own crying. What? What's this sound? Why can't he speak? Wait, where is he? Why can't he get up? ...Uh? Why is he... so small? ...what happened to him? _________________________________ - Error!Sans is a variant of the character Sans from the game Undertale. Error!Sans was created by LoverofPiggies aka CrayonQueen - This story is inspired by 'Healing what has been broken' by harrish6. Although it happens in a different way, Error will still fall into the VOID. But instead of just falling into a different Multiverse something else happens. - fgod Error concept belongs to @harrish6 - Undertale belongs to Toby Fox Mar 8, 2020

    So I had just started my Undertale obsession (and I didn't feel like playing the Genocide route for YouTube). I enjoyed the game so much that I decided to make an Undertale fanfiction! Nine-year-old Meg loves her mother more than anything else. No matter how hard life is for her, she always hugs Meg, makes her smile, and tells her an amazing story... one about the world of humans and monsters. But then a war broke out between the two races, and the humans won, sealing the monsters underground. Meg loves hearing this story, and it inspires her to be a kind person. But when her mother dies, Meg is forced to live with her abusive father and stepmother. They yell at her for every mistake she makes, call her by her real name (even though she hates that), and worst of all, they keep trying to erase her mother from her life. Eventually, Meg can't take it anymore, so she runs away to a mountain.... and falls in. During her time under the mountain, she quickly learns that her mother's story was true all along. And now she must find a way to give that story the happy ending it deserves. Chapter titles are named after the background music of Undertale (The story is gonna be converted to a comic version, so be prepared for those changes) Credits TobyFox (for creating this amazing game) SpiraRed (for convincing me to draw the art and for Jim the Froggit) RoseAngelino (for improving my drawing of the barrier)

    The soft piano music playing in the background makes you take a small breath, you stare down the man in front of you and take a deep breath. Maybe what he said the first time you met has some real meaning. Judgement will come, and it's here for you today. The cover is not mine, it is by TheHorrorPainter on DeviantArt This story contains mentions of sexual assault, explicit sexual acts, self-harm and suicide, panic attacks and violence and swearing. Take caution when reading and keep in mind that there will be lots of detail. Also note that in the story I have chosen to take a few creative liberties with the readers appearance, such as eye color, hair color and length along with a few other things as they come to mind. And please do not be deterred by the very short first chapter, I promise that they get longer.

    One year ago, the Wild Easts famous North Star proclaimed his love for a sweet human hiding out in Snowdin and -much to his surprise- they reciprocated that affection, marking the beginning of their long-distance relationship. Today marks their one-year anniversary and the Sherrif couldn't be happier, or more nervous. Everything has been planned right down to the finest details. Now... if only he could figure out what exactly you should give your beloved partner on your first anniversary... (For some context, all characters who are canonically dead in UY will be alive in this. I won't say who to avoid spoiling those details for people.) Credits: As always, if I have not given proper credit, please let me know so I can go back and fix it. I do not own Undertale Yellow, I just really love this game and wish there was more Starlo content. He is such a cute little dork! I highly advise playing the game, there was a lot of work put into it and the developers are very talented. I believe that it was led by a developer that goes by Master Sword and the team behind it is listed on the Undertale Yellow Wiki page. I chose to use the cover art for the Undertale Yellow game, which can be found on the wiki page as well.

    The adventures may be over, but Bo-ran, Voblyss, Vonn, Levi, and the family are far from done causing chaos. 😂 From Vonn's unforgettable first birthday to Goku dropping in for an epic battle show, and Levi discovering some seriously suspicious Undertale coincidences, these bonus stories are packed with laughs, wholesome family moments, and completely unexpected surprises. No prophecies. No cosmic apocalypse. Just the family being the family. 🎂⚡😂

    Cinco anos após a libertação dos monstros do Subsolo, a Superfície provou não ser o conto de fadas que todos esperavam. Na dividida cidade de Ebott, a frágil paz entre as duas raças está desmoronando sob o preconceito e o medo. Do lado mais sombrio da humanidade, ergue-se os Capuz Cruzados: uma legião extremista e cruel armada com uma misteriosa magia corrompida, cujo único objetivo é o extermínio total dos monstros. No centro desse barril de pólvora está Frisk (16 anos), que atua como embaixadora oficial. Exausta, frustrada e com o psicológico profundamente comprometido pela impotência política, ela carrega um um grande fardo. A força policial local, liderada por Undyne e pelo primo e único familiar de Frisk, Ryan, luta uma guerra perdida contra vilões que a lei comum não consegue parar. Mas o jogo muda drasticamente com a chegada de três primos órfãos à cidade: Mary Soury (25 anos), a protetora e lider da familia; S/N Soury (16 anos), um garoto de coração gentil e magia de fogo; e Kaza Soury (16 anos), um prodígio arrogante, descontraído e absurdamente forte, capaz de controlar forças de atração e repulsão gravitacional. Quando os caminhos desses adolescentes se cruzam nos corredores da Escola de Ebott, faíscas colidem. Enquanto o deboche de Kaza se torna a distração necessária para aliviar o estresse de Frisk e irritar profundamente a paranoia de Chara, a bondade pura de S/N estende a mão para salvar o psicológico da embaixadora. Agora, marcados como alvos principais do implacável capuz cruzado, humanos e monstros precisarão entender que a Determinação sozinha não basta mais quando o mundo decide sangrar.

But she discovers something that immediately sets foot and makes a huge issue surround her and her family. (PLEASE NOTE / READ: 1. This is a multifandom / crossover story. But that doesn't mean that some characters you're expecting to be in this story, is going to appear in it. 2. Most of the characters IS NOT MINE. Most of these characters are from indie video games and shows. Please give credit to the actual creators of the characters. Original game / show names are the tags. 3. Even though there won't be certain characters in this story, there will be references. 4. PLEASE DO NOT BOTHER IF THE CHARACTERS DON'T "seem like themselves in the game/show". I'm trying to make most of these characters at least lore accurate but this is my story. These characters who I don't own, will seem slightly different in the story but I promise you, I'll make them halfway accurate but they'll need to lean more into the lore.)

This is here for anyone who's interested in my funny writing. By the way, I use a big clunky computer that was made in 2011 to write and post these, I felt like including that.
