Alone in a condemned world where monsters and humans fight for power constantly, Y/N survives off of the wood's riches and the small scraps of shelter she can find in ghost towns. Allies and friends have come and gone during the war, either killed or have parted ways. It's not all that bad. She could be dead, after all. One afternoon when shipments from the Human Capital come on a train, she meets a mysterious stranger who saves her life. He's a monster, no doubt, a skeleton to be exact. Y/N is intrigued by the monster and decides to follow him into the next town over where he disappears into an abandoned warehouse. Y/N follows him in only to be pinned to the wall for questioning. After answering all his questions, introductions are made and Y/N learns that the skeleton's name is G. Y/N likes G despite his hateful nature and somehow convinces him to let her come along on a quest he's taking to save his brother from the Monster Capital where they took him for war. After surviving assaults, the government, and Mother Nature herself, Y/N and G start to form a special bond that neither of them wants to break. But when everything goes wrong and neither of them is strong enough to prevent it, Y/N finds that the capitals that she had always hated are far more sinister than she could've ever imagined.

(This story contains 18+ subjects. Please read the tags.) You're at your limit. Life has never been the kindest, in regards to you. But now, it's just getting to be too much....something has to give. So, you decide to make a change.... ....and as a result, fall down a giant hole. Yeah, life's funny like that.

Humanity is divided over one thing---the Monsters' reappearance. Some believe that they should stay aboveground, and others think that they should be sent back to where they came from. Then, there are those like you who don't quite know what to think yet. What will happen once you become acquainted with two skeleton brothers? Will you finally decide your standing on this issue? And is it possible that you will find love along the way? Thanks to crispicroissant on DeviantArt for letting me use their artwork as the cover of my story!

You're a human that has fallen into Mt. Ebott on the year where all humans dress as monsters...Halloween. So how will the monsters know if you're a human or not?

You were working with Alphys in the lab in Undertale when chaos strikes! In a freak accident, concentrated determination is mixed with an unnamed concoction and blow you through a dimensional rift. When you reawake, you find yourself in what seems to be the beginning of Undertale once again. Upset but not overly surprised, you make your way back to Alphys's lab... Only to find her lab assistant is no longer you! Working with Alphys now is a tall, punkish skeleton with two cracks in his skull and a snarky attitude. As they help you find your way home, will you find more than that? *I DO NOT OWN UNDERTALE OR GASTERTALE!!! I WISH I DID BUT I DO NOT! THIS IS JUST A FANFICTION!!*

Monsters always fasinated you. Ever since Frisk broke the barrier and freed the monsters, humanity didnt take it too well but they are slowly getting used to it. Slowly. Very...slowly. (btw Chara is depicted as a female in this story, and so is frisk. Dun be triggy) HEY ALL! This is my first fanfiction EVER! so dont judge. [NC 16] at some parts :>

It was just a normal Saturday. (Y/N) was playing Undertale for the millionth time. She was obsessed. (Y/N) had played all of the routes. True Pacifist, No Mercy/Genocide, Neutral. She experimented with killing certain characters doing different things. Then, as (Y/N) started a new game, she felt a falling sensation, as if she just fell out of her chair. She blacked out soon after. When she woke up, she was lying on a bed of golden flowers. She knew this place. (Y/N) was in the game. She had taken the place of Frisk and was in the Underground. •Disclaimer I do not own Undertale. It belongs to Toby Fox. I do not own you. You own yourself. I do not own the cover or any of the pictures that will show up in this book• *If you're reading this as a guy please just change the pronouns to he/him/his. I find if a lot easier to just put female pronouns. Thanks! :3 *

It had been a couple months since your little sister went missing. Guess how surprised you were to see her on the news with the headline "Young Girl Helps Monsters Escape". When you meet the friends she made in the underground you can help but to love all of them, especially a skeleton with a love for puns and stars. Sorry I'm not that good at summaries X3 This is my first story so please tell me if I misspelled anything. I view frisk as a female so I apologize if you view them as male or both.

> Your just a regular human that fell down the hole that supposed lead to the underground, you come across many obstacles and find yourself in much of a sticky situation, more or less your tied up. •IMPORTANT• Hello wattpad users, this is actually the first story I'm actually making. So I'm sorry if it's suckish or terrible, but it's my first try I'm sorry! Ahem.. Anyways... I'll try to update once or twice a week and if I ever forget, then....then... I don't actually know what I would do...but anyways enjoy!
