    Underfell Sans is abused by his brother Papyrus and he just wants it all to end. He has been told he is useless and worthless and other things like that so many times he has started to believe them. This is my first book thingy and I'm only doing it for fun and to vent a bit. Don't expect anything good, it's going to be a shitty book

    Summaries... my worst nightmare... Anyways, the characters of this book are not mine, they are from their creators of Undertale, Underswap, Underfell, etc. etc. Ever since the Alternate Universes of Undertale found out about each other, they started to come together in one place that lets all monsters from all Universes in. Only a few do stay there. Cover Art was created by me, DO NOT USE IT FOR ANYTHING ELSE, thank you.

    [^w^;] So... New description and cover art! Yay! Ok, let's go! "What's the point in existing, when you're worth nothing?" We all know that the Underfell Underground is one hell of a place to live in, literally! So why should someone as weak, yet adorable, as Sans be living there? He's trapped, he can't get out and all he has left is his brother, Papyrus, who he calls Boss. Not that Boss is helpful, all he does is degrade him and make everything worse. Why should he have to suffer as much as he does? Why can't he just have a better life? ... Why can't he just disappear? Be careful what you wish for, they say... GAH! I STILL SUCK AT SUMMARIES! BE READY IF THIS SUMMARY SUDDENLY CHANGES! {News flash: It did. ^^^} (READ) Changed it, no fontcest, or at least, it wasn't intended that way. However, you guys can still interpret this the way you want! Also first chapter is all my tags because wattpad won't accept them T^T Why wattpad? Why...?

    Geno is a lonely thief, resident of a small sea village. His past is covered in darkness. Somehow he can't recall who he was or his parents. He only had his 2 younger brothers. But he lost them long ago in a pirate attack. Only he barely survived from the 3. Since then he became cold, close to himself and without someone to care, loosing even almost the ability to feel. Stuck in the island, he steals food to live. Everyday is almost the same, thinking he'll just rot and die here with no family. But fate had other plans for him An old prophesy writes that he must go to the 'Tearful Cave'. Stories say that it keeps abandoned cursed treasures. That it's the gate for a kingdom deep down below. And that if he doesn't go, something terrible will happen as he had been seeing in his nightmares for years And before he even realises it, he gets involved in a great adventure. But not alone, as he gets stuck with the Reapers, one of the most famous and fearsome pirate crews. Just great. Nothing worse than pirates. Geno hates them so much, sometimes he's surprised with himself But as the time will pass, he'll realise that in this crew, everyone has an interesting story to tell of their lifes before becoming pirates. Unexpectedly with them he'll make the biggest friendships he could ever make, see new lands, face dangers and enemies. His associating with them, especially with an enigmatic priest, will teach him to cooperate, soften his hatred and anger, heal his broken soul, feel again solidarity and for the first time, he will fall in love But through that adventure as he will travel, he will also discover himself, uncover the story of what happened long ago including his past, learn who he truly is, understand his connection with the kingdom in the depths, become even more determined to save the seas and the world and reach his destiny But what if when an adventure ends in reality it's still at the beginning?

    ...I'm Undertale trash. This is basically going to be the story of Undertale retold as the Underfell version. I'm sure something like this exists already...but whatever. The story is told from Frisk's point of view, and it's the Pacifist version because Genocide scares me. Anyways I hope you like it!

    It was the roaring 20's. Swing music was at it's prime. The atmosphere of New York couldn't be more lively. Gang wars were also at its peak. The Gaster brothers were at the top of their field. However, little did they know, and old friend of the eldest Wing-Dings Gaster, was coming out of Retirement, and we wanted to play the game once again. Along with him, he brought, the innocent looking Doness Shapple. Seemingly human enough, but what the humans of new york city didn't comprehend at the time, was those pure angelic looks, could be of deviously deceiving. (Inspired by StaringBacks "Sooner or later, you're gonna be mine)
