Humorous Sanster. I made this on a plot generator, please don't murder me. not NSFW, so enjoy. (I will possibly write a full sloppy-ass story of it later.)

An alternate version of W.D. Gaster from Undertale, Perfectionist doesn't vary too much from the mysterious and popular character, except... he never died. Perfectionist is a version of W.D. Gaster who never perished within his own creation, and otherwise last creation, the CORE, and reached the surface along with the help of the human, Frisk. Except, when he came to the surface, all he saw was chaos. Sure, he saw this in the Underground too, but, he figured it might've been due to their circumstances, being locked in a cave and all. Surely that would have a negative effect on one's character? Alas, even in the openness of Ebott City (for lack of a better name), the cruel ways still slithered into the minds of all Gaster faced. He could not stand this, he could not fathom it any longer... something had to be done. Gaster... -no, Perfectionist took matters into his own hands.

In the undergrowth,time has reseted.As usual,Sans is the only one who remembers Frisk and how they freed them,only for the world to weirdly reset later on in the year.He knows what will happen in this reset.Frisk will come,kill everyone,kill his brother and then he would fight them and end up dying. But what if this time he was wrong? What if this time it was different? What if this was the last reset and the power of the direction it went, laid in the hands of just a teenage girl? ____________ ((I havent seen the ending or played the game yet. I only know half the Genocide and Pacisfist endings.If I ask questions please answer in the comments if you have time :) Also, there may be some trigger warnings and some of the characters personalities will be modified throughout the book.

When Stars's past was dark and confusing, someone came to help and give some clarity. After that, Stars never saw the stranger again, until he is in the void. A Fanfiction about Stars and my OC Z, just for fun Stars by Bunnymuse Z by me

The fall lasted for mere seconds, and yet it felt like an eternity. The adrenaline rushing through your veins proved useless, as there was nothing you could do. You hit the ground with a hard thud, instantly knowing that it was very possible you could've broken a few bones. However, astonishingly, as you flexed your tense muscles, you were fine. No broken bones, but not without bruising or aches. Opening your eyes, you took in the endless black void surrounding you; and yet, you couldn't believe your eyes. And, as a hopeless feeling started to set in, your eyes fell upon a small light object in the distance. Undoubtedly, it was a home. A bright, big house in the dark abyss. Without hesitation, even in your pained, confused and terrified state, you started to set off in the direction of the house. You knew it was your only hope in a place like this. But, what you didn't know was that you were going to get much more than a shelter to stay under. Much, much more. All credit goes to Bunnymuse for the Gaster Gang! Photos not mine unless said!

One day, Sans fell sick. His sickness came out of nowhere and it cannot be cured no matter how many medicines Gaster gave him. Because of the sickness, Sans stayed still on the bed, just laying down or sitting on it under the blanket. The sickness can be seen from his face, half of his white skull was a little bit darker than the rest. Gaster and Papyrus had no idea what kind of illness Sans has, but they decided to take care of him no matter what, hoping that the sickness will soon gone either because of the medicines Gaster gave him, or disappears itself. But alas, The sickness gotten worse... -------- UNDERTALE (c) Toby Fox --------- This have nothing to do with Undertale's canon characters or story. This is just a fan story I made because the idea stuck in my head for a few while and I'd like to share it with all of you. So, enjoy!

It was a pleasant night for (Y/N), that is until a portal traps her in a place with magic talking skeletons. Will she be able to leave or will she be stuck there forever? If she is stuck, then will it be a good thing or a bad thing? The gaster gang, music, and art aren't mine. I will state if the art is mine.

Even though the Underground is now empty, except for some people, you still stupidly managed to fall in the once prison for monsters. Who knew you would get away from the prison with someone following you behind your back? Who would have known an echo flower would have revealed too many things? Who would have known you'd fall in love again? Words count: 55.608

"No no, my ego would never leave. It's part of my charm~" "I'm pretty sure that charm is just bullshit.
