Fonttale by MegynHamilton

Fonttale is an AU where skeletons have a special power related to their font name. A Normal Font Comic Sans for example, can force people to laugh. However, Papyrus is a Horror Font and they're much different from Normal Fonts. This is where and why the story begins. Papyrus is a sadistic murder whose main goal is to protect his one HP brother Sans. By day he pretends to be an obnoxious idiotic skeleton obsessed with puzzles and spaghetti, but at night he teams up with Flowey and patrols the area for humans in order to collect souls to break the barrier. When he isn't doing that he visits the MTT Resort where his brother does his comedic acts and kills monsters he finds in the alley in order to keep Sans safe. Unfortunately as time passes and more and more monsters disappear, the "Resort Killer" becomes everyone's favorite topic...including Undyne's. When Papyrus decides one day to take a chance, something goes wrong and Sans discovers more than he ever wanted to about Papyrus, the Underground, and even himself. The line between right and wrong becomes a blur, and his relationship with his brother is tested as he tries to help him overcome his apparent madness. But is it really Papyrus that needs help?

Conduit Tale-An Undertale Fanfiction Novel by Serena_Walken

(Complete)Hopeless and in despair, Sans never thought he could escape the resets and continues caused by FRISK that tormented his life. But, when he thinks the kid is possessed and stops FRISK once and for all he finds out ... that he never really knew anything after all. No more resets. No more saves. No more hiding. Life will never be the same for the Underground. Souls and Science can be an unforgiving bitch. Relationship: Because of the nature of the way this fanfiction works, there are several Frisks. He knows all of them, but Sans only falls for one, and she is definitely over the age of 18. This doesn't blossom until some time later though, as this is way more than a sweet romance. Buckle up for some tragic dramatic scifi-twisting to the fantasy world of Undertale!

One month before Frisk falls into the Underground a different human falls, someone that is not from this world, but from ours, and now they have the power to change the world as they please.

Into Hell - Book Two of Into The Game >> (Sans X Reader) by Melody4164

(Y/N) is finally ready to go back to the monsters she holds so dearly. After about a year of mental and physical training she has finally gotten her emotions under control. But has she gone emotionless? After plugging the thumb drive with her save file on it into her computer, (Y/N) soon discovers something. In a desperate attempt to save themselves, or maybe just a way of revenge, Chara corrupted the save file. Now, all the monsters that (Y/N) befriended are out to kill her. Can (Y/N) survive? Will she defeat Chara and find a way to get her friends back to normal? Or will she instead join Chara and erase everything? Find out in Into Hell. Once again I'm making the gender pronouns she because it makes it so much easier to write, which means quicker updates. I'm really sorry if your a male.

Haunted!Tale (COMPLETE) by sapphiremoon86

What if the story of Undertale had gone a bit differently? What if Flowey was the harbinger and dealer of misery and pain manipulating the ghost of a long lost child and a hate filled monster to bring about the spread of misery and pain to the underground as well as above? Follow Frisk the seventh soul as she inherits the house with a portal to the underground in a haunted houses basement. Don't mind the smell and watch your step as we enter the Haunted!Tale's house. Cover: By Me, picture actually taken in the Wizarding World of Harry Potter in one of the shops. :P

A Different Kind of End - Book One - Reset by Toasty-Writer

Hatred is like an infection, if left to fester it only spreads and becomes worse, until there is little to no hope of return. Frisk had abandoned her life on the surface, she had no expected to survive the fall, even less so make friends with the monsters rumoured to live under the mountain. So what happens when she leaves and is all alone once again... What happens if she listens to the flowers advice..... Book one of A different kind of end. I do not own Undertale, or the characters used, simply the story concept.

Red Eyes [Chara X Reader] by CouldYouJust

This story is inspired by many other works and may bear some resemblance in certain places. However, I will endeavor to make this story it's own. 2 years ago monsters were released from the underground, ending their centuries-long imprisonment at the hands of ancient humans. Not a soul remains in the underground. But that doesn't mean no one's there. Be it chance or fate, The First Fallen will soon meet an all too curious human as he ventures into the deep beneath. The Reader or [Y/n] is male and Chara is female. I apologize if this bothers you it's just how I've always seen the character. Disclaimer: I don't own these Chara-cters nor do I own Undertale. This is just for fun. This story's rating is [M] for explicit language, violence, suggestive or sexual themes, and fantasy/fictional violence. My lovely reader @NightTheDemon1 told me that the artist of the cover is a Twitter user known as @A___IRAA. Thank you!

Reckoning Tale-An Undertale Fanfiction Novel by Serena_Walken

(Complete)Eighteen years ago, Frisk left the Underground, but there was another barrier to face before the monsters were freed. When Frisk comes back as an adult though, she must pass tests that 'destroy her human soul' in order to save the monsters, and Toriel won't allow it. Banished and unable to return, Frisk is stuck back on the surface. Knowing that freedom can only be won with 'humanity', Sans goes to the surface to trade Frisk some of his 'monster' for her 'humanity', so he can help too. However, neither of them know where these tests will lead . . . or how far the truth really goes. A barrier is more than a gateway . . .

Into The Game >> (Sans X Reader) Undertale FanFiction by Melody4164

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 *

FurtherDown by THEANIMATEDFOX4

Was this truly the last RESET? Sans wondered. But he knew only Frisk would tell, only this young girl would decide his future. He hated the thought of it at first, but hatred began to grow numb after he figured out he had no say in his own future. He had to admit though, Frisk was pretty reasonable, it was Chara who was the maniac. But she was gone now, so what was the anticipating, eerie, feeling that he had in his bones? The feeling that something wasn't right, of course, this timeline was already incredibly strange. The feeling sat in his in the pit of his stomach, tying itself into knots, until that fateful rainy day when all of his questions would be answered. So basically, this is a fanfiction of a fancomic of the game Undertale. Look, I'm gonna admit, I'm little stuck in the Undertale fandom, so this is my of slowly crawling out of it. Anywho, I strongly suggest you read the fancomic which this fanfiction is based off of, DeeperDown, before reading my story. Here, I'll give you a link. http://gettingdeeperdownwithundertale.blogspot.com/ Anyway, enjoy the story, it took me about 11 months to write, so please consider enjoying it, seriously. - Ya Boi, Fox
