Summary
"your bro?" Red-guy said suddenly, eyelights bright and alert. "you're lookin' for him aren't you?"
"uh, yeah." He blinked, startled out of the already fading memory.
"tall, loud 'n screechy maybe?" Red-guy leaned in, now uncomfortably close and he started to miss when he kept his distance like a defensive stray.
"…not the way i'd put it." he said and the third significant realization of the night hit him like a truck "well if we're talkin' 'bout the same guy i'd say we have to be brother's too."
"i…guess?" Red-guy's already cat-like sockets narrowed at him in consideration "maybe we were estranged or somethin'."
He nodded along.
That sounded about right, Red-guy seemed like the kind of guy you'd want to be estranged from. Not that he had many options in terms of companionship at the moment, so he exhaled and sluggishly got to his feet.
"welp. i'd say that doesn't really matter anymore." He said and let out his hand to help his brother up.
"…guess i could do worse." red-bro said from where he was still poised underneath the tree.
Or
Red and Comic get dropkicked through space and time into a jungle with a bad case of amnesia. Obviously they must be twins.

Summary
You wake up as someone who has nothing left to lose, stranded in an Underground that's slowly dwindling in life. Despite being capable of crossing the barrier, you don't dare to, when you have a personal endeavor and promise in mind.
It's a different story when you're transported into an ideal alternate timeline, where your oath is rendered void. Here, with your various counterparts, you don't appreciate reliving the life of a prisoner-- especially when it's enforced by a reflection of what your Sans could've been.
(OR: In a pacifist timeline, an alternate Sans possessing a human soul appears, risking the newly established peace between humans and monsters. If Classic Sans had hair, he's pretty sure he'd still end up bald.)
[A Various x Sans!Reader fic.]

Bookmarker's Notes
(7/??)
Reader is sans o al menos quien tiene el control del cuerpo mientras sans está dormido (;parece que sans Hiba a ser polvo si oc no hubiera a aparecido, alma de sans dentro del alma de perseverancia del oc)
Reader es un sans con marcas moradas, gafas moradas y pantuflas moradas el resto es blanco la clásica ropa de sans sin contar la bata ( ese sans se casó con alphys en una linea neutral, quien le dejo un reloj después que ya no pudo estar para que siempre sienta que ella está con el , se fue a una linea de tiempo pacífica donde Comic arreglando la máquina saco a más hermanos pero nunca a uno que pudiera atravesar su barrera, en esta todos los monstruos esqueletos que llegaron no pudieron salir de la casa cabaña de Vainilla -

Summary
You were so tired of the lies and abuse. Ever since you took Jessica up on that offer, you had been living in a nightmare. Now you wanted out.
It's time to confront Sans with your truth. How, you might ask?
Why by whipping your soul out.

(Continuará? 2025)
Au Undertale casa de los esqueletos
Versión alma gemela (pero no destaca por eso sino porque mc es culpada de hacer cosas horribles por Jessica la novia de los esqueletos)
Pero mc tiene un alma hermosa y se rebela la verdad (parece que todos descubrieron que mc era su alma gemela pero mc les tiene miedo por todo el abuso verbal , físico y emocional pero no los odia)
Mal o mejor momento vinieron los Sans y papyrus de Horrortale (mc al ver cómo los discriminan como hicieron con ella se llena de VALENTÍA) -

Summary
You were just walking home. A tear in reality split open underneath your feet and suddenly you were falling.
Falling
FallingThen you fell up and onto the tiled floor of a basement lab.
Now all of a sudden you're in another world and surrounded by 6 strange skeletons (plus one's brother).
Being terrified of all things horror and monsters, what are you to do?*Will contain mature themes but no smut*

Au Undertale pacifista
Versión Almas gemelas (resonancia)
La casa de los esqueletos el clásico de traer versiones tuyas pero está vez solo de Sans (de un tipo específico de Sans, horrortale, Flowertale , Dustale , Error y Ink )
El Oc tiene miedo a los MONSTRUOS (de fantasía, en su mundo no hay monstruos ) se adapta
Esqueletos flechadoz automáticamente o en proceso
