When Worlds Combine ~ Sans X Reader by Geekgamergirl101

Frisk was a good friend of mine, despite the age gap. About a week ago, they disappeared, only recently found. It wasn't long for Monsters to return as well. I, in all honestly, am scared. The world will be changing, and change never comes easy. Frisk seemed happy, though, in fact so far it's been okay. Frisk introduced me to all the monsters, becoming great friends with many of them, in fact... I've even fallen for one. Unfortunately, I doubt love between a human and a monster will ever be okay, especially when humans have already started to react towards the monsters negatively.

One stormy night she found a castle and entered it to hide from the storm. Not knowing who was the owner she proceeded. Hearing whispers in the dark she ran until she collided with someone.

UnderBound: The Fallen Monster by GumballFan13

We all know the story of Undertale, about a human who falls into the underground, befriends everyone or kills everyone, but what if during the war between humans and monsters, the monsters won? This is the world of UnderBound, a tale about a monster who falls into the underground, and meets various humans. Except, these humans are various Earthbound/Mother characters. Join the fallen monster as he goes through the underground, encounters strange humans, and make friends.

Warning! There is a chance that there will be spoilers for the pacifist run of undertale. I recommend finishing that before reading this. There won't be any spoilers for the no mercy run, so don't worry about that! Also, don't worry about anything NSFW/lemon if that's not what you're into-there won't be any of that here. You're a human that's fallen down into the underground. You've decided that you'll stay instead of going home after fighting Asgore and sparing him. Now, you had made some great friendships while in the underground-but one of those friends in particular was one you'd like to be a little more than friends with... Aaaa an X reader fic! I haven't done one of these before, but I hope you still like it!

All the monsters have been released from the underground but what happens when creatures full of lust meet some smexy humans Note: was originally inspired by written love on quotev BUT does contain a plot COMPLETELY different to it so if you have the audacity to comment about this READ THE FIC FIRST and then tell me it's similar to something you have read before

It's Not Possible ( Nightmare x Killer ) by jesus_davito13

It's almost the end of highschool for Killer, an 19 year old student at a human and monster school on the surface. Killer isn't ready to leave the highschool yet as he's afraid he can no longer see his English teacher again. So he decides to spend each and every day with his English teacher as mush as he can. But how will others think of this close relationship with the high school English teacher?

Undertale: Guardian on the Surface by BrandenSchneider

Branden and the Monsters have finally gotten to the surface. But things aren't as simple as they hoped it'd be once they got out of the Underground. Humans fear the monsters more then they did before and force them to live out of their city behind a wall. Monsters are patient and understand that they are a frightening sight after so long, and leave it to the ambassador to try and make things right. Frisk still has much to do though, as she and Asriel we accepted to go to school in the city while their brother, Branden, continues to train and protect all of Monsterkind. Eventually, his patience runs thin and starts to take things in his own hands, but will he make things better? After all, Frisk, Sans, and Branden all remember what happened before getting out, vividly. Will they be able to make things better, or will they get Monsters even more problems?

A story of friendship, trust, heart break and high school life. A group of friends survive their last year in high school and each go through a stage of challenges testing their friendship and trust. Will they all find their happily ever after?

When Frisk falls into the Underground, she is horrified to discover the world of monsters is every bit as evil and broken as she had been told her entire life. But when she meets Sans, she wonders if there is love inside some of the monsters after all...

An Undertale AU where Monsters won the war instead of Humans. Both continue to live in peace. Atleast, that is to be believed.
