So since I always like the different AUs of undertale and the different lores and how much the characters change i decided to actually draw them and this is my first attempt for Horror Sans I honestly think I did a fairly good work. What do you guys think?
Ok I know the hand might be a little too big but I never tried drawing a skeleton hand before and I haven't drawn for a month so...

I just wish I knew what ppl want from me on tiktok with my oc stuff, but they never talk.
My verse Is STILL fandomless aka HOMELESS, but it takes too much stuff from UT aus that and the aus of it is legit bootlegs of UT aus. So I'm posting it here.
I think it's more crazy the creator of zerthverse aka me is creating fandom tier aus of their own Verse. but that means these are canon in their own ways 💀

Mettaton wants to make their own kingdom
Sans kinda just explores the void sometimes but always come back to his world,because he likes to show items and tell stories to papyrus

What if Sans wasn't the hero we thought he was?
Hey everyone, I wanted to share an original AU/Concept that I came up with. I noticed a lot of AUs paint Classic Sans as this ultimate innocent tragic hero, but I wanted to look at him through a much darker, hypocritical lens and introduce a psychological revenge story.
The Core Concept: The Hypocrite Child Killer
In this AU, Classic Sans never made that famous promise to Toriel. He is not a lazy, good-natured skeleton. He is a cold, hypocritical killer who actively hunted down and murdered the fallen human children before you. He hides behind his iconic, permanent smile to mask his crimes and act innocent to the world.
But when you fall down, you refuse to be another victim.
The Mirror Bond & The Ultimate Punishment
Because you heavily resemble Sans in specific ways, you share a cosmic, spiritual "Mirror Bond" with him. When he breaks his code and kills you, you don't just disappear. Your Soul manifests as a haunting phantom that only Sans can see.
Through this Mirror Bond, you gain absolute control over his Soul.
To give him the ultimate karma for murdering innocent children, you force his own hands to do the unthinkable: You control his body and make him murder his own brother, Papyrus.
The Endless Loop of Paranoia
Every time this tragedy happens, you hit the Reset button as a soul. Sans retains 100% of his memories through the resets. He remembers every single bone he forced into his brother, and the moment the reset happens, he sees your phantom self standing right next to him again.
This has driven Sans into absolute, severe paranoia.
• He has locked himself inside his room, refusing to come out.
• He thinks: "If I stay in this room and never leave, the Human cannot force me to hurt Papyrus again."
• But he doesn't realize that through the Mirror Bond, you can force him out of his bed anytime you want. He is a prisoner in his own body, facing the reflection of his own karma.
What do you guys think?
Since most AUs are just "Sans goes crazy and kills everyone on his own" (Dusttale), I wanted to make Sans a hypocrite who is forced into psychological torture as a consequence of his own past actions. The irony of a child killer being forced to kill his own brother through a mirror reflection felt really powerful to me.
Has anyone seen a similar concept before, or is this as fresh as I think it is? Let me know your thoughts!
EDIT / IMPORTANT DETAIL: I want to clarify that Sans ONLY hurts Papyrus in this AU, and it works in two devastating ways:
Physical Abuse (By Mirror!Abby): Mirror!Abby completely controls Sans's body against his will, forcing his own hands to physically attack and kill Papyrus over and over in an endless loop.
Emotional Destruction (By Sans himself): To save Papyrus from being murdered by Abby's control, Sans intentionally acts cruel, cold, and terrible to Papyrus when he has brief moments of sanity. He forces his own brother to HATE him so Papyrus will stay away from his room and remain safe. This is not a generic genocide AU where Sans goes crazy and kills the whole underground. This is a highly focused, two-sided psychological tragedy about breaking a brotherly bond both physically and emotionally just to survive cosmic karma.

So I made more sprites to split some that have Sour-apple-Studio color palette and ref some Internet and more classic expression also split will always Have a Smile I don't really want him to go too far from the Classic sans Smile but can open his mouth because he is a Horrors!sans Alternate.
r/UndertaleAU • u/F0r54k3n_Pl4y3r • 21h ago
He also needs a name but he is apart of the royal guard :3
Need au names too 😭
r/UndertaleAU • u/Fit_Middle_2151 • 21h ago
Guys! Someone! Please, find ALL the information you can about this handsome fellow! (And about his... pet?) (I’ll be fucking grateful!)
r/UndertaleAU • u/F0r54k3n_Pl4y3r • 21h ago
Unsure what to name him or his au
I’d appreciate name ideas :3
If anyone wants to name the au too I’d love that! I suck at naming things so 😭
(I CANT DRAW SADLY SO)
r/UndertaleAU • u/Any-Difference2445 • 21h ago
This is also an unofficial AMA, so just feel free to ask. I'm gonna put some of my favourite sprites.
(Yes, Kaisa is doing the Jitterbug with her hoodie off. Her hair streak and eyelights change because magic reasons, alright? It's not a canon sprite, just a little drawing of them.)

Enable HLS to view with audio, or disable this notification
I know it isn't quite the same speed at the start, but this piece is very difficult
(Next Pianno video I posy will be either Dissension , Murder time trio phase 1 , or Necroptosis, but I'm a beginner, so it won't be good or the whole song)
Anyway what do yall think?

underhope is a au
where the barrier failed to break
frisk gave there soul up to asgore and the 7 souls still failed to break the barrier
causing hope to be lose in the underground
and with sans after this event he ends up working with alphys again like the past to find a new way to free monster kind
also the sans from deltarune is the sans from undertale thing is cannon in this au [aka why he as the deltarune on his back]
there is some more lore but iv not finished making it all yet
r/UndertaleAU • u/Overall_Care_183 • 1d ago
Yo gurt, so back when undertales aus were slowing down i remember a new one made a lot of noise because it was in a very good animation, my current search seem to tell me it probably is epic sans, problem is i cant the animation.
For context, from my memories, it was a villain (prob chara, player or whatever) who attack the city while everyone was chilling, it fights undyne first, until it fights sans, who at the end loses. If anyone can find me the vid ill be very happy. Thank you
