The advantage of having such a huge adoptive family is that you're never lacking a place to stay. But sometimes the learning curve on "how to care for your tiny human" can be a little steep.

Lucifer is an abused child who loves to play Undertale. The major problem with that is that he love to play the Genocide run of the game. What happens when a familiar blue hoodie wearing skeleton drags him into the game to end him once in for all. Will Lucifer survive, will he change his ways, and most important will he have a bad time.

The last Sans ever saw of Papyrus was his agonised expression. His hand was outstretched, reaching for him but too far away to hope to even graze his own hand, and he was shouting. Error found it maddeningly hilarious. UNDERSWAP

Sans always watched the timelines reset. Because of a freak incident, the timeline was contaminated. A mysterious figure told him he had to go in and destroy the hate, but this timeline was more than contaminated. Everyone was dark, twisted. One by one, Sans must save the Underground, before the Underlord destroys him...but who is the Underlord? UnderFell AU

The barrier's broken, and Frisk is living a peaceful life with her new family. She still has a huge challenge ahead of her. He has six yellow petals and tends to verbally abuse anyone who dares to even look at him. She's too determined to give up, but she just can't break through to him. Maybe she doesn't have to. Maybe someone else can get to him. Someone who understands him.

Just a drabble I made of Sans fully breaking the fourth wall and talking to the player/reader as they play undertale. Also in doing so, Sans figured out how to reset. I'm not sure if I'll finish it, but it was a fun concept idea and it is actually near 11pm now so, have fun reading it.

"Hey look, it's monster girl!" Some people bully Frisk, and Sans gets very angry about it, which leads to some sad conversations, and a narrow avoidance of a very uncomfortable one. BROTHERLY AND PROTECTIVE SANS! CONTAINS THE F WORD, DON'T READ IF YOU'RE VERY YOUNG AND GENTLE. FRISK GOES BY THEY, AND "MONSTER GIRL" IS MEANT TO BE MISGENDERING.

Frisk comes down with pneumonia and they are very unhappy about it. The monsters try their best(?) to help. (Part 3 of my Dreams of the Past and Present series) (Cover Art courtesy of dogpu on tumblr!)

Sans is gonna give whoever is bullying Frisk at school a bad time. Gender neutral Frisk, post pacifist run.

A series of one-shots in the Undertale universe. See individual chapter for details. Chapter 4: Cause we're snowed in, get it?

Hello all, this is my Medieval Au for Mystery Skulls animated. Only my oc's are mine, MysteryBen owns his.

An AU where monsters were not banished to the underground, but rather, live in their own restricted areas. The relationship between monsters and humans is tense, and the two races mostly keep to themselves, so what happens when a runaway human child gets adopted by monster parents and enters a new school filled with many strange and quirky monsters?
