Summary
Much as you like animals, you ain't afraid to snuff one out. And when the door’s left unlocked, you let yourself in with the surety that this here cock-holster understands that. Should know his future consists of a bit in the teeth and a grave to match.
Yup, monsters have invaded your home: high-ranking royal steppers, dark romantics, and base shittery that has said neighborhood a’ yours alive with protest. You just got outta jail, and now you gotta make another mess.
In your own house, no less. Just awful. Plain and awful, it is.
***
An unconventional menace of a reader looks to enact revenge over the skeleton that took her home.And later runs over a guy and probably his dog and maybe his wife and just possibly his kids, and, it cannot be confirmed by any means on whose grandma was at the scene but—if she bears any relation to our man of honor—she now bears more relation with the road.
—Hanlon's Razor: never attribute to malice that which is adequately explained by stupidity.

Summary
Your name is Sans Serif. Your identification card says so. Your work permit says so. Your residential assignment says so. Your brother’s dependency papers says so. The Ministry says so, and so it is true.
But when you and your brother are rudely pulled into a peaceful alternate universe at the worst possible moment, the entire foundation of your identity is put into question. You are one of several. One of possibly more. You don't trust any of this, especially not that human, yet you can't help wondering... should you even try to go home in the first place?
Or
An old fic I started in 2018 and decided, hey, why not revisit it in the good old '26? Machine troupe but you are a Sans, and make it an Anti-Harem.
...Oh, and did I mention totalitarianism? -

Summary
ESP: Despertar en una jaula no estaba en tus planes.
Tampoco perder tus recuerdos... ni descubrir que ciertos nombres duelen cuando intentas recordarlos.En un lugar donde la luz del atardecer se filtra entre el polvo y los secretos, dos hermanos esqueleto te observan con más atención de la que deberían. Uno es ruidoso, orgulloso y demasiado protector. El otro sonríe como si nada fuera grave... incluso cuando lo es.
Y mientras tus recuerdos se desvanecen, una pregunta empieza a pesar más que todas las demás:
¿Qué parte de ti no quiere ser recordada?
------
ENG: Waking up in a cage wasn’t part of your plans.
Neither was losing your memories… nor discovering that certain names hurt when you try to remember them.In a place where the light of dusk filters through dust and secrets, two skeleton brothers watch you more closely than they should. One is loud, proud, and far too protective. The other smiles as if nothing is serious… even when it is.
And as your memories begin to fade, one question starts to weigh heavier than all the others:
What part of you doesn’t want to be remembered?

Summary
It wasn’t his fault. Papyrus didn’t know everything Sans sacrificed to raise him when he was little. He was a child himself, all on his own. Nobody ever taught him any better. But Papyrus was here now. He would be the comfort Sans had been seeking for so long. He’d let him pretend he was protecting him. It was the least he could do to cheer him up, to give him a purpose. But until his last breath, he’d protect his brother.
———
A oneshot in which Papyrus takes care of his terribly sick brother.

Being a creator themselves they hated the way that XGaster treated his creations but their wasn’t much they could do about it seeing as it wasn’t exactly real, but reincarnating into UnderVerse they were going to use this opportunity to beat some sense back into Ink, and make sure XGaster lost his life privileges and XGaster’s bitchass was going to pay, and his victims would get JUSTICE. But what was JUSTICE? And what was VENGEANCE? Could they make sure not to fall into VENGEANCE or would they even care if they did?
Also if they might be able to help out a pair of lovers along the way and see one of their favorite ships come to fruition, well, no one could blame them~
But can the others at least stop calling them kid!
