Asgore Stories

The untold story of the evacuation-- from Alphys's point of view. Attempts to remain as close to canon as possible. Cover image is from her official artwork in the Undertale Arcana set. Rights belong to the artist.

Corporal Adrian Shephard, a US Marine Corps soldier assigned to the HECU division, was sent off to Black Mesa for 'cleanup duty'. Despite the hell he went through, the marine somehow manages to escape the dangerous, alien-ridden facility against all odds and, after being 'detained' by the ever elusive G-Man, is then assigned a new mission many years later... to the UNDERGROUND! Accompanied by Chara Dreemurr, the first fallen human turned apparition, the two journey through the unprecedentedly large Underground for one, very specific goal... but what exactly was it? And is that all there is to it? In... time, all will be revealed.

If given the chance, would you start over? After falling into a timeline where nobody was murdered, his mother never died, and his father was never erased, Sans should be ecstatic that he has a second chance with his loved ones. But there is no denying the trauma he'd been through, either. Everyone is supposed to be dead, after all. What if Frisk comes back to take it all away again?

Lord Beerus, the God Of Destruction, finds himself in the Underground with a small child. With no way to leave, he travels the Underground with the strange child he met, meeting new beings known as monsters. Will he do what he does best and destroy everything in his path to get out? Or will he find some new friends on his journey?

We know the story, The Angel looses their vessel, possess The Cage, meet The Girl and The Prince, and an adventure of friendship and mystery ensues...but this isn't that story. This story begins 15 years before the original events. A human wakes up in the forest with no memory of who they are or how they got there as they try to get their bearings, they hear the sound of a baby's cries. And on that night, Hometown gained two new members. All characters belong to their respective creators Oc and story belongs to me

Is it still considered a backstory if the protagonist doesn't exist? Companion story to "Reset".

Every timeline. Every choice, decision, friendship, death... Was it really all just a game? An Undertale AU where Chara gains sentience and realizes that these "endings" and "routes" are all just a game. An Undertale Fanfiction I wrote when I was much younger. It's really bad, but this story holds precious memories. It definitely gets better much later on, but please bear with it's humble beginnings. I was hesitant to post this at first, as Undertale had died down considerably since its release in 2015, but this story is precious piece of an era when life was better.

Warnings, headcannons and ships In this AU everybody is human, Spamton is Noelle's godfather and Tenna is a friend on Toriels and looks after Kris when he visits. There is no 'darkworld' Ralsei is homeschooled but lives near Susie Uhhh, start with the warnings •there might be smut, if there is I'll put a warning in the chapter name, but it wont be for too long •mentions of drugs and alcohol •The word j*b will appear (censored) •spamton is trans ftm but like, he's had all the surgeries (this is my own headcannon) There will be other ships, such as Implied kingkaard MAYBE Kris and Berdly Susie and Noelle Lanino and elnina Jevil and seam PolyMike (Mike, cowboy Mike and cat mike) Mentions of spamvil and mikeTenna Headcannons! Spamton- •Trans (had all surgeries) ftm •tooth gap •good liar •drug addict and alcoholic •awfully oblivious Tenna- •Has attachment issues •Insecure •praise kink •also awfully oblivious •smart •doesn't understand sarcasm •loves being entertainment guhhh, this is like, FILLED with head cannons, so eerrr if you ain't open to people having different opinions you probably shouldn't read, I LOVEEE spamtenna, but-uhh I'm not THAT great at writing as them so, a lot will be inaccurate :-(

Entirely new reimagined of Glitchtale where there would be many changes that are not seen in the show. Some of them may be controversial, but some I think should've been since the beginning I suck at writing still so I'm trying my best Credit to Toby Fox for making Undertale in the first place since it's a wonderful game I love it story Glitchtale however, is a different story. It's creator is very controversial so I would try my best to stay away from keeping a lot of the things from the show. I know it's an AU but I consider it as a show some of the changes I can say right now is that Chara will now be a female look at a bit controversial, but it would make sense because frisk is a male and Chara should be the female that's the change I would do, but I'll get to all the changes soon enough since the first chapter of release is all the changes though stay tuned Also, I'm 17 while I'm doing this

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)

A bunch of Undertale short stories! ... Which, despite the cover, are not only about Frisk, Flowey, Alphys, and Sans. There are other characters in there too. Aww, who'm I kidding? Probably 90% of this is skelefam fluff 'n' feels.

[3rd book] So it's yandere Undertale One shots because I can. Also because some characters just kinda need to be more recognize. Slow updates? Or it will just Update at random. Also there might be some errors so sorry about that. Started - 4/9/23 Ended - 5/31/24 I don't own Undertale or the Characters! Not the Cover I just edited it!

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
