au cross fanfiction reader readerinsert sans underfell underswap undertale undertaleau underverse xtale

what happens if you were there instead of sans in 0.0 ?
what would have happened if cross took a human soul instead?
would it change the entire timeline of underverse or just... leave it as it is?
would you die in a try to stop the x event, or ,will you fail?

...and most of all.. who are you?

------------------------

just an idea i had while wanting to see what would have happened if there was reader insert and there isn't a lot of those online.. 
beacuse all season 2 didn't come out yet I'm going to focus on season 1 trying to not get too lazy and discontinue the story if you like it leave a comment it would mean so much to me see ya in the fanfic

Also, y/n is using all pronouns(didn't want to only do they/them, and is aroace(don't expect ships at all in this fic, it is focused on the story)

yours truly,

New Souls (Cross Sans X Reader) by TheLunarGem

You are a somewhat normal girl that explores with your friend, you are a secretary person until you meet a dashing skeleton by the name of Cross but one thing still remands on your mind, why do you exist if you have no soul? This fanfic will have an abused and depressed reader in it, so if you are sensitive to those topics I'd advise not reading this fanfic. Also, this will NOT. I repeat NOT turn into a lemon, so this book will be mostly age friendly, I mean it will have some gore in it, you have been warned Credit to the cover art https://goo.gl/images/osxoh5

Inky Mistakes. ( Reincarnated!Reader) by UnFlirty

~I don't own the characters, or images, but I do own the plot and headcannons, but if I did own anything popular..

Undertale X Reader [In Remake] by Cat_Maipie

Let's get to the point shall we? So let's look at the list here... You're a... no information? Hm, interesting i guess, I'll have to base it off my observation. Whatever, you're a human, well kind of. You're a human and a monster at the same time, more like in between. Let's say... player? Better than nothing i guess. You're your own person. Sometimes you control frisk, sometimes you don't. You can also move through timelines, and also universes but that may be too risky huh? You'll find more about it soon...

Won't You Stay My Little Honeybun? by Krembell

You were the assistant to Alphys, her co-worker tinkered on a very curious machine in the same department you worked at, incidentally that co-worker was your chosen soulmate. His name? Sans, Sans the skeleton. You didn't really spend any time with him or rather he was purposefully avoiding you, knowing that he also knew you were soulmates tethered by a soulmate connection. The only reason he allowed you to be around was mostly because of your ability to put things into your memory with excellent accuracy to remember important things like a certain blueprint or a recipe for medicinal use. You had tried multiple times to befriend Sans but everytime he looked quite uncomfortable so you stopped trying to force him into a friendly relationship. One night you had been left alone with the curious machine as you had leftover work to do and one event led to another. You wish you hadn't cut the string.

✘ 'Two Connected Souls' Undertale Sans x Reader Soulmate AU by Bunny-Crystal

(DISCONTINUED) 'A young girl has just been living her life normally; until she turned thirteen--the age where you can find your soulmate. That was when this young girl and their parents--found out that her eyes not only changed colour, but she also had a tattoo/soulmark.' 'For years humans have been born with the ability to find their soulmates by eye colour. The first emotion you feel when you turn thirteen is the emotion that causes your eyes to change to your soulmate's.' 'Monsters have been able to find their soulmates by a tattoo of something that represents their soulmate. Humans, however, do not have tattoos unless they are a monster's soulmate. If this is the case, the 'soulmark' as it is referred to as, will only represent the monster soulmate and will be the single soulmark used to find the other half. A monster can find their soulmate by either of them touching the other's soulmark without having any bandage or piece of cloth in between them. Although rare, it is not uncommon for a monster to have a human for a soulmate--so what if Sans did?' WARNING!: This was a basic summary, I will be adding in a bit more information! Although this IS an 'X-Reader' fanfic, (and my first at writing one) I will be giving the reader heterochromia eyes. You will be able to choose what the colour of her right eye is--but for the sake of this story, her left eye will be green. 1st Book in a Series! AND YESS, the reader will be female. (Sorry guys!!!) I Do Not own Undertale, it is owned by Toby Fox! I do not own 'reader,' you do. (The cover art is the soulmark.)
