Inspiration!! I am a-okay with people using my stuff as inspiration, I understand what it’s like not being able to get your ideas onto paper. If you do use parts of my work, please credit me!!

Please, please, PLEASE be respectful to one another, the internet can be harsh so it’s good to have some peace once and a while :)

Ideas for Characters in The DEADCODE AU:

I’ve already been thinking about these characters and drawn them a few times, but I’ve never been able to come to a satisfactory design for some of them…

I’ve been to nervous to post any art on here /srs

I’d genuinely love feedback and what I can improve on (story elements, lore, etc.) for my ideas

Tell me what you think!

Marionette/Idk Puppet ig:

Centuries old human soul inside a mechanical doll/puppet, human woman used to be a vessel for a god, human got so old she died of old age, god struggled to find new vessel before making a deal with a scientist/artificer to make the “perfect vessel” in return for a wish

Human soul was some kind of blue, now faded + trait has faded/puppet has become more flat and emotionless

Puppet made out of reenforced porcelain and gold

Eyes are always closed (does not need them to see), doll design is similar to Evolved Humans from Arcane

Does not eat or drink, pretends to for normalcy (cup always empty, no food on plate)

Still has large amount of magic even though soul is faded (story lore)

Tasked by god to protect the DC, will complete tasks asked by those around vessel

not given full consciousness of utmv, if full awareness was gained, would (or try to) eliminate all threats in multiverse

Multiple copies of puppet are available (story lore)

The Scientist/Chisel/Solly/Vikky

Mad scientist character based off the common misconception about Frankenstein & The Monster, brightly colored and slightly manic, very hyper and irresponsible

Redesigned 3 times already, serious pain in my ass

Part human, part goat/sheep monster, part ???

ENA vibes, multiple voices

Maybe a Chara & Asriel glitched together and into DC instead of becoming Hypergod (hence the name “Chisel”)

Very immature, but very intelligent—didn’t really grow up and was never taught good or bad morality

never ever EVER meant to be romanticizing mental issues/trauma, character will have a darker story and issues addressed in storyline

Was given a wish by The Puppet’s god, it’s a secret :) (I do not know yet)

Just a silly lil’ guy :3

Soul is almost sewn together, 3 different pieces, still has imperfections

Zphyer/Motorcycle Head/ The Guard

A Papyrus who glitched out of timeline right as he was dying from genocide run, wears a helmet to cover injury, close with The Puppet

Has no head, eyes & mouth are visible still

Playing off the “cool” aspect of Papyrus, less empathy towards humans but still has a soft spot for kids

Very “too cool for school” punk vibe, has a motorcycle, very cool and awesome /hj

Misses his Sans, wants to get back to him even if he’s not alive anymore

Soul is cracked and glitched, less amounts of magic, focuses on physical attacks

They are very much the “The Brains, The Brawn, The Something” dynamic

If there’s any feedback you’d like to give, please feel free to tell!!! I want to improve my writing skills and character development, so it’s be super helpful!

No pressure, of course :) /gen

Hope u liked it!!! ^—^’

[the-deadcode-utau]

I have more:

Mainly just side characters, avoiding using preexisting characters to get my creative juices flowing

Human necromancer with a kindness soul that revives people for short periods of time to give them and their families closure, has two(2) ravens and overly large overcoat

Head scientist monster with a pressure gauge for a head, working on fixing the core

Worm-on-a-string monster, just a silly guy, very helpful, maybe a messenger?

Trashcan Wizard, exactly what it sounds like

Ringleader circus skeleton monster? Based off The Puppet’s old design, cheers up new residents

Hematologist bat monster, studies the differences in the blood of others who got transported to the DC, makes sure no new diseases are spread

Tiny bell children, have bells for heads, jingles when talking/moving

[xtaleunderverse]

Now that Underverse 0.8 Part 1 is finally out, it’s time for me to step back and take a break from the series. It’s a bittersweet decision... seeing the amazing reaction to this episode makes me want to dive right into animating the next parts. But I know if I do, I’ll fall back into the same cycle of emotional burnout I’ve faced over the years. To break that draining routine, I need to stop for a moment. Underverse will be on HIATUS FOR 1 YEAR AND A HALF.

HOWEVER! I’m not disappearing entirely! I’ll still be working on the XTALE 21 YEARS comic, hosting Ask the Xtale Gang events, and occasionally creating short animated content. This break will also give me a chance to focus on my original project, METADORA.

I’d be lying if I say I'm a little worried about people forgetting the series during the hiatus. But I need this break, and I can’t thank you all enough for your continued support and encouragement. Even during tough times, knowing that this project was born from a mix of improvisation and silliness, has brought joy and inspiration to so many people reminds me of my purpose in this world. And I want to keep doing that until the end.

I hope to return with renewed passion and strength to finish this journey that has taught me so much not only as an artist, but as a person as well.

Thank you for being with me.

See you until 2026.

UTMV DEAD CODE AU Ramblings

⚠️WARNINGS: talk of body disfigurement, mental issues (?)

DEAD-CODE DEFINITION: A section of code in a program that is not used or accessed during the program's operation. It can refer to code that is never executed, or code that is executed but has no impact on the program's output. It’s a deceptive element that can be found in software projects. It can waste time and memory, and often goes unnoticed. Removing dead code can change the program's output and create bugs, so compilers are usually conservative when removing it.

AU DETAILS:

The Dead Code AU (or the DC) is a small pocket/“mini-verse” that is composed of unused, discarded, or thrown away code from other AUs/timelines.

The small pocket contains characters, music, objects, and backgrounds; which is glitched into the Dead Code area when the timeline is started, reset, or overwritten.

When things are transferred into the Dead Code, the effects can be mental or physical. The glitch will mainly affect actual characters and their souls/bodies, although music and objects can also be affected.

Some examples of the effects are: missing certain physical features, glitching soul/body, glitched magic (can have positive or negative effects), and insanity/negative mental symptoms.

Unused V.S. Discarded Codes

Unused Code— When code never ran in the timeline it was made for when the timeline started. Whatever isn’t used to begin with is an Unused Dead Code.

Discarded Code— When code is removed or replaced when the timeline resets or is overwritten. Whatever is no longer used is a Discarded Dead Code.

Unused Codes are a lot more stable, due to it never being in its timeline and never becoming physical. Discarded Codes are a lot more likely to be unstable and mentally unsound(if it even can be) due to being ripped away from its timeline without warning.

Environment and Community

The environment is very similar to the OG Undertale timeline, however some parts are more dangerous and glitchy than others. As far as the people who are in the DC know, the surface doesn’t exist.

The more dangerous parts include Hotland and The Core, as the unloaded chunks of magma and rock makes it hard to traverse.

Because The Core in the Dead Code is not functioning properly due to the transition to the DC, the ventilation system has been compromised. Any scientists who are able have been tasked with studying the area and fixing The Core.

More medically knowledgeable people are tasked with helping others who have been affected/disabled by the transformation. They are working on finding ways to restore others to their original forms, however no positive results have been recently reported.

As the Dead Code grows, so does its community. There has been a very simple government program established, with some laws and regulations to keep things orderly.

Most ‘citizens’ in the DC are assigned a patch or pin to wear that resembles an unloaded texture (pink and black checkered pattern), it symbolizes safety and stability for those who wear it. (Stable + Unloaded Patch, SLP)

For the more unstable and mentally unsound, the caution tape pattern is used. It can be shown in different ways such as jewelry, belts, clothing, etc. It symbolizes danger and power for those who wear it. (Unstable + Dangerous Patch, UDP)

Most people have a SLP, but it’s not uncommon for some to have both. If they do have both it’s most likely that they’re unstable but not that dangerous or powerful and vise-versa.

[phorksintooutlets]

A Undertale AU Idea:

The Dead Code AU, where characters, assets, backgrounds, music, and all other unused or scrapped code resides.

When something or someone is unable to “load” into their timeline or is discarded from the code, they end up in what is essentially a small pocket/“miniverse” that acts as a hidden file in a computer. One way in, one way out.

I’ve been thinking and developing this AU in my brain but I was afraid it would be too much like the Omega Timeline. I’ve used it mainly as an AU for ocs of mine to take place in, maybe I’ll post art about it later.

Things I’ve thought about adding:

When a piece of code (character, background, etc.) is unable to load or is forgotten/unused they’ll glitch out of their original timeline and into the Dead Code.

When they glitch into the Dead Code, the effects can be mental or physical. The glitch will mainly affect actual characters and their souls if they have one, although music and objects can also be affected.

Examples of this would be things like: characters missing certain physical features or body parts, souls glitching and affecting the person’s abilities/magic, or just having a part of their brain/soul removed or missing.

Body Horror is definitely a major part of this AU, along with musical distortion and more darker themes

The Dead Code is not a very safe place, as most things there have missing parts and aren’t finished.

I thought about making the “caretaker/creator” of this AU being a puppeteer of sorts, my main inspirations being Caine from TADC, Simulacra, Monica from DDLC, and The Other Mother from Coraline.

I’d love feedback and suggestions! Feel free to create a character if you’re interested!!

I made a blog for it because I like being organized 👍
