    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.

    There's only one rule for those capable of AU hopping: never bring a real person into the Undertale multiverse. But, like all rules, it was destined to be broken. | - Error Sans x Female Reader - Young Error - take places not long after he becomes Error - so he mimics his canon version more closely at the start before molding into my fanon version with experience - This intentionally doesn't follow the exact plot of Aftertale either - Achingly slow burn - I abuse Y/n more than necessary (oops) and Error is toxic pre-character development. This isn't meant to portray a perfectly healthy relationship, but show that perhaps even the worst person can change - The friendship dynamic is: bffs that insult each other for fun (while not meaning a word of it) & I include a lot of what's deemed 'filler' content b/w Y/n & Error (y'all just 'hanging out') bc there has to be a solid foundation for Error of all people to care about someone else - Expect a heaping helping of banter 👍 (I couldn't help myself)

    [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

    INSPIRED My name is Cross, I live in an apartment with my husband, or rather ex-husband, Epic. We separated for legal reasons ten years ago but we're still together, the reason being the debt Epic had put over us. However I still called him my partner. Despite the fact we're in debt because of him, I work two jobs to help. He works an office job. It's the way my life's been now. But something changed. There was a customer at the coffee shop. He was apparently a regular. I hadn't paid much mind to him at first. Until it all changed one day. My Poison Apple

    This is a rewrite of my other book Musical Souls, which is still up on my profile if you'd like to read it :) I'll add in a more personalized description as I get further in, but for now here's just a few little facts. This is a sans x reader! Pretty much normal Undertale Au but with a few small changes. Nothing to notable. Main character is a musician with a rough past, and lots of depression and anxiety issues. She loves to sing and share her ideas, as well as give advice; but tends to only open up when she is wearing her mask. A bit of a slow burn, but not annoyingly slow, as I tend to get bored with writing the same content over again. For a good while they will both be rather oblivious though. Animals (specifically cats and dogs) are common in all of my books especially this one. There will almost always be a cat with the main character throughout the entirety of the book. Sans will interact with normal main character as well as her alternate ego, and for the most part stays clueless in the beginning. Chapters tend to be anywhere between 950 words and 3000 words. I like to find a natural close to each chapter and sometimes it takes a while. Anyways I hope you enjoy.

    You were adopted by the Bad Sanses as a kid because- well, you were a baby so you'd die alone if they didn't take care of you. You grew up with them becoming like a family to you. It's your birthday, you make a wish as you blow the candles, tomorrow is your first mission, corrupting Dream so that no more positivity exists. Quite a lot to take in right?

    She was born a princess, but her name became the reason the world below was sealed away. When a monster from Mt. Ebott took her as a child, her father's fear became a blade. He cast the entire monster kind beneath the mountain and raised a magic barrier over the only cave leading out, trapping them underground for eternity. The surface healed. The Underground did not forget. Years passed. Y/N grew up behind castle walls, a gilded prisoner in her own home. Then came the betrothal-Prince Adrian, polished and powerful, the alliance her father had waited for. But the heart doesn't ask permission. In the shadow of her duty, Y/N found herself falling for someone she wasn't allowed to want: Connor, the castle's knight. Loyal, quiet, and the only person who ever saw her instead of the crown. With him, the walls felt less like a prison. With him, she remembered what it meant to breathe. Adrian saw it. And he ended it. Connor was gone. And Y/N was bound to the man who took him from her. Marriage to Adrian became a gilded cage with sharper edges. Every day was a reminder of what she'd lost, and every night was a fight to keep her spirit from breaking. Until one day, when the impossible happened. The knight she mourned returned. Not as a memory. Not as a ghost. But as the man she loved most in the world.

Afraid, of the faith might brought on to them they just braced for the best. This fanfic is made around 2022-23 so don't expect good things especially at the first few chapters of this book!

    You know...she really thought that'd be it. That after obtaining as much power as she did, she'd be left alone. No more insane adventures, no more confusing places...just her and her Underverse she protected. Waking up in a dark forest with limited power was NOT on her to-do list.
