Sans has lived through countless timelines. He's seen the kid make friends with everyone, only to give up in the final moments. He's seen the kid killed, over and over and over again. Sometimes, he'd even done the killing himself. And no one ever remembers. Not even the kid herself. It's an exhausting cycle, one that never seems to end. But there's something different about this run. Another human's fallen down... the kid's sister. Please note the the story is primarily on Quotev, so updates to Wattpad may be late, or lag behind that of Quotev. The story also has the potential to become mature. (I haven't decided yet.)

You're a human who has fallen down into the underground. There you meet a certain skeletal scientist and his sons. Will you get close to the family or will you become their enemy. Loosely based on TheBombDiggity666 Dadster comics (which you should totally check out if you haven't already) and occurs before frisk's appearance. Also artwork is not mine~

The reader is a wizard, beings with the shape of humans but the magic of monsters. Wizards were forced into the war between humans and monsters by the humans. There, she meets the monster general, Grillby. Cover photo belongs to: http://ask-grillby.tumblr.com

It is a undertale genocide run but has some major tweaks in it.anything undertale related belongs to DAT BOI TOBY FOX..And some of the ocs is obviously mine, but try to follow along And don't hate. Idk If I will continue it your guys choice really...enjoy! It wasn't a normal genocide run like you have seen it before .The human was confused but didn't care that there were more new important monsters. It means more EXP and LV for them . Now they have to face a more difficult monster that is angered at them for killing his two sons and daughter. Who will win this battle to the death? Chara or Gaster?

Frisk has gone back to hell to visit her friends, but, something is askew this time. But no one really knows what. They eventually find out. Not before many people are hurt. The cover is taken from the Undertale AU Wiki and is edited to me, shout out to the original author for this amazing art, sadly I could not find their name or page. This is a sequel to Immortality, so please check that one out first for a bit more contest than diving into this head first. But hey, if you do dive into this head first, good luck.

You never want to test a wolf's loyalty to the pack. Especially if they are willing to decorate the walls with you. They always say ignorance is bliss, and it is when it comes to a certain family. Just don't overstep your boundaries. No one has ever seen or heard the boss of this mafia, but everyone knows them. Be careful which family you mess with, or the last thing you'll be seeing are red eyes.

In the business of human trafficking, mercy isn't a well known word. You and your crate mate, a child named Frisk, are obidiently waiting to be released to a 'master' when havoc breaks out around you. Guns are fired and you're doing your best to protect Frisk when your crate is pried open by unfamiliar faces. How will you fair with your first 'friendly' experience?

[There aren't a lot of stories that I've seen about this ship... And since I ship Sans x Frisk, it seemed appropriate for my tastes. If you don't ship it (Like you Mettaton x Papyrus fans) then don't read it!] Thank you~ Edit: This is incredibly old and cringy so read at your own risk XD

It's about a human Princess who fell below and meets a monster Prince. They didn't know they were actually in love. Go with the Princess to meet new friends, discoveries and the history about the humans and monsters from the past. Will she be able to get her happy ending? • • • {under editing <---sequel will be published on September 2018} [Cover is mine ^^]

We all have it... the tattoo that will bring us to our mate... but.... is that easy? they can be really far away... but what if he/her actually really close without we knowing it?
