alphys asgore asriel crossover dreamsmp flowey papyrus sans tommy tommyinnit toriel tubbo undertale undyne

A large project I've been working on for about a month. 
------------------
Tommy runs from exile, and decides to hide in a cave in the mountains. Until he falls down into a hole and into a mountain, where he stumbles upon the world of Undertale. Now he has to find a way out of the underground and back to the surface while also keeping up with his memory of everyone he knows.
------------------
Preview:

Tommy continued to run up the mountain until he came upon a shaded edge along it. There was a large opening that looked like it would lead to death if you fell down it, so he knew he had to be careful. 

He carefully walked along a path, that looked like it was human-made, but then, he heard a noise. 

It sounded like a skeleton so he quickly swung out the iron sword he had with him as a chance of protection. He thought he heard the noise from behind him so he turned around to look. 

He was then suddenly struck by an arrow to the shoulder, and he fell down the mountain... 

Falling.... For what seemed like like forever.All Rights Reserved

Undertale:Secrets by ItIsComic

Remaster on my page - check it out! Sans has had an interesting past. A past that even his beloved brother barely even knows of. A past that he wishes could remain a secret. But when the questions start being asked, what does he do? These questions seem so little, yet they cause so much to happen. One little question. "Who is ??????" can change so much. A chain reaction from a single sentence can cause an entire world to crumble. Or maybe two. This is my first book so dont expect anything great.

A Tree, For Us (Sans X Reader) by TheAbandonedQuiche

CONTAINS SPOILERS FROM BOTH PACIFIST AND GENOCIDE RUNS After a horrible situation, I (Y/N) scaped from home to avenge my (sibling). In a failed attempt, I got lost and fell through a hole, in there I found another world... "the underground". I meet many friendly monsters, one, specifically, changed my whole life. Both of us will try to give the monsters the liberty they deserve. And this is how all happened... (Cover made by me :3)

L.O.V.E. (Yandere Fem Undertale x Child Reader) by Unidentified562

You live in Ebott City and you hear a story at the beginning of summer about the cursed mountain next to the city. You wanted to do something exciting for the summer and to you... What was more exciting than going to a mountain with a monster on it... Try falling into a hole into the kingdom of monsters where they accept human boys and men with open arms, but treat human girls and woman like the enemy due to them being sealed away by them.

Most Powerful Monster by thundersnake2375

I'm writing a fanfic on the popular game, Undertale. You fell down into the Underground at the age of 11, but little do they know that you had secret powers, at least until you got carried away. None of the pictures or videos belong to me.

A Strange Feeling (Sans X Reader) by Sak423

Do not expect consistent uploads as I am a college student🙃. This is rated mature because of strong language. You are a 24 year-old in college and have loved Undertale since the beginning. You enjoy all the aspects of the game; the story, the lore, the music, the backgrounds, and most importantly the characters. You've started having a strange, almost malicious feeling related to the Genocide run and that creeps you out. So, you start a pacifist run and after a while, you fall asleep. You wake up in Undertale and thus begin your new journey. Through your travels, the strange feeling comes back, but as a different emotion. Perhaps the only one that can help you with this feeling, is a certain punny skeleton. (I tried my best I'm not very good at summaries 🥲.) (Also I am so sorry for the kinda weird writing this is my first time writing a story. So I welcome constructive criticism.) Started: January 26, 2025 Ended: ???

Knock Knock {A Sans X Reader - Undertale} by LittleFluffyAlpaca

You were always a curious child. One day, your curiosity took you too far. You lived not to far from a mountain, MT. Ebott, and always wanted to see what was on the top. Your parents had told you stories about the mountain and you had always wanted to see if they were true, being the naïve child you were. One day, you reached the top after a while of climbing. You looked around, not realising where you were walking and fell into a gaping black hole. You woke up to a soft voice of a goat-like monster who, ever since that moment, took care of you and loved you. She taught you magic and all sorts of recipes. Everything she knew and you loved it. But what happens when you grow up more?

Bloodfall (An Undertale AU) by BlackStormWolf

Ever since the death of his younger brother. Things have gone downhill in the surface world for Sans. Alphys died a few months after Papyrus to a disease, Mettaton and Undyne, especially Undyne, had fallen into a depression. Flowey dissapeared into mt. Ebott, not to be found and Sans is fighting depression and insanity. One day, Sans discovers a suspect to his brother's death. A being that is trapping anyone who had either fallen into Mt. Ebott or stayed behind in snowdin for a while. Sans, along with Frisk and Undyne, go into the underground themselves to confront this being. They must encounter the Bloodfall that traps and kills anyone who dares pass by waterfall. (This takes place after a true pacifist run if one killed Sans in a Genocide run, but reset their game before getting to Asgore(I did this in a way to quit the Genocide route). This is if Frisk choses to do this the Pacifist way. I might make a Genocide one in Story Shorts. Also, My Sans is a human, but feel free to interprate him as a Skeleton if you ever choose to use this AU. Just credit me!)

Universal Surface Angel by Lithriel

Reader insert. What if W.D Gaster didn't just get split between time and space, but actually ended up in your world in an abandoned hospital you called home? Your were a young child he decided to use as experiments to test human determination in said world and breaks physical laws to test human possibility? He knows of the powers you gained from his experiments... all but one, this one allows you to tear realities just enough to teleport into them. Knowing of Undertale you felt bad for the monsters stuck below in their world and wish to help them, but something goes wrong and you end up going to certain AUs and helping them, gaining the attention of some bad skeletons who now desire your power for them-selfish-selfs.

Royaltale Season 1 by Uni_Da_Queen

This is an Undertale AU I originally planned on making back in 2019 but, I wasn't capable of making all the character designs and forgot about it for two years. A few months ago, I thought about redrawing the only two designs and reviving it as well as changing most of the original plot and instead of making a comic series, I'm writing it so it will be easier to think about more designs. OCs are included in this AU. If you would like yours to make an appearance, message, or tag me to discuss when they can appear. This is season 1 of the series and it will basically follow the events of Undertale because there was a strange, unexpected reset after 10 years of living on the surface. Now, it's up to Frisk to help her friends remember their lives before the reset and save the world before Flowey tries to kill all of humanity as well as monsterkind and Mystickind. Can the determined human survive yet another perilous journey through the Underground or will everyone fall to Flowey's hands (leaves?)?

Repo Man (Mafia!Sans x Reader) by morrow-

In a startling post-apocalyptic world, society is divided into two orderly classes. The human race stands on top, untouched by nuclear war in the city of Chicago. Monsters are at the bottom of the food chain, confined to live in run-down apartments, minimum wages hard to come by, the backbone of the work force in Chicago. They often find themselves the victims of senseless violence, dropping by the dozens each day. Tensions rise and anger grows between the two groups, a civil war seems all too likely. And with humans and monsters so scarce after a nuclear war that ravaged the planet, they cannot afford anymore losses. All at once, at the wrong place at the wrong time, a human finds themselves thrown into the midst, and the fate of the planet may rest in their hands.
