[arplenoon-art]

Welcome to my blog!

I'm Phoenix, a traditional watercolor artist who makes Undertale Multiverse art and fanfiction. I also like making spooky doodles and little paintings.

My UTMV AU is called JumpVerse. It's an enormous project where I am rewriting all the lore of the most notable Sans AUs into a consistent canon that includes popular ships and shipkids. You can follow updates to it @jumpverse

You can find my fanfiction on ao3 under the name “arplenoon”

The main story I'm currently working on is Dreamtale Emancipated, a Dreamtale retelling with different lore and magic system meant to be more like a traditional Undertale AU.

An Archive of Our Own, a project of the Organization for Transformative Works

Or on my Youtube channel, you can find audio versions of my fanfiction:

If you'd like to follow my original project, it is called The Mending of Jonah, a horror romance.

If you just want to see whatever crazy things I reblog or are interested in, you can follow @arplenoon-reblogs. (It is chaos and there is no consistency)

If you would like to donate to help support me and my work, you can do so on my ko-fi. Information about my commissions are also there. (Note: If you intend to commission me, please DM me with the exact details of what you are seeking. Otherwise I might suspect you as a bot and block.)

Frequently Asked Questions

Asks are open to direct towards any character in JumpVerse or myself, Phoenix, the creator.

I apologize that Anonymous Asks, however, are turned off. This to protect my own mental health as I've seen several bad apples in the community use this feature to bully creators, and I know it's something I am sensitive to.

Nightmare trying to ignore all the problems he's caused and pretending to be normal... At least Crescent wouldn't realize how bad things really were until much later...

[jumpverse]

Okay fine.

My brain has decided that Nightmare, is in fact, genderfluid.

He just refuses to admit it. For reasons.

he's a horrific war criminal but it's his first time wearing a dress be nice to him

Underswap for JumpVerse Notes

The following is a proposed list for swaps for Underswap in JumpVerse. These are just my personal notes as the current story I'm working on spends a great deal of time in Underswap.

Swaps from Canon: Toriel – Asgore (Humbleburg is more run-down than New Home. The Ruins are now a sealed off museum with everything cleaned up and neatly marked with descriptions and history.) Chara – Frisk Monster Kid – Asriel (due to Toriel and Asgore's immortality, Asriel is now Toriel's nephew rather than son.) Flowey – Temmie (Instead of landing on a bed of flowers, Chara lands in a display of Temmie plushies in the museum gift shop.) Ruins Dummy (Dumbest Dummy) – Mad Mew Mew (Content Kitty Cat) Jerry (gets no swap) (Dr.) Papyrus – (Junior Cadet) Sans (Papyrus is still 19 but was a prodigy working at the lab since he was 12. Sans is still 29, and worked with Gaster on the trains up until 2 years ago when Papyrus suddenly retired after an unknown accident. Papyrus drinks honey and smokes. Sans makes tacos and his special attack is a magic mallet. Papyrus sells crepes instead of hot dogs at his part time stand.) (Dr.) Undyne – (Captain) Alphys (Undyne is more into comedic American cartoons rather than anime, eats microwavable TV dinners rather than ramen. Alphys is teaching Sans how to knit and sew rather than cooking.) Mettaton (Mettablook) – Napstablook (Napstaton) (Napstaton's shows are focused more on sports, vehicles, concerts and documentaries rather than cooking, fashion, plays or news) Grillby – Miss Muffet (Grillby sells broths and sauces and overcharges, dresses flamboyantly. Muffet's cafe is breakfast themed and they're questioning their gender. Muffet's cafe was still owned by Grillby, who is a greedy landlord.) Nice Cream Guy – Burgerpants (Conductor) Gaster – (Dr. Person) River Person (The river has been swapped into a railroad.) Bratty and Catty – (Hopper and Scales) Royal Guard 1 and Royal Guard 2 (Greetings Bird) The Bird TCYOADSG – (Carry Onion) Onion San

Proposed Swaps:

Gerson – Aaron (Aaron is now old and fought beside Toriel in the war. Gerson is now a young man who shows off his muscles.)

All the Snowdin Guard dogs that are white are now black cats. Doggo is now a tuxedo cat. (Feel free to speculate about possible connections to Friend from Deltarune.)

Biome Changes:

Mt. Ebbot – Ebbot Valley Ruins – Pristine Museum Snowdin Forest/Town – Sunnedout Woods/Village Honeydew Inn – Savory Grill and Lodge (from Undertale Yellow) Waterfall – Lavafall Garbage dump – Fossil dig Echo Flowers – Vibration Stones Hotland – Hydroland CORE – ENGINE (instead of drawing energy from the core of the earth, the ENGINE produces energy from wind pressure in the Underground) MTT Resort – NPT Hotel New Home – Humbleburg

The residents of these locations fully swap with different locations unless otherwise specified: (Personalities may also have swaps but I'm not going to focus on that unless I have a need to.)

Snowdin residents are sent to Hydroland (formally Hotland) and NPT Hotel (formally MTT Resort) and vise versa.

Ruins residents are sent to Humbleburg (formally New Home) and vise versa.

Waterfall residents are sent to the ENGINE (formally the CORE) and vise versa.

Knowledge is knowing Sans is the weakest monster in the Underground.

Wisdom is knowing not to fuck with Sans.

S!Gaster: "Oh, is that an accent I hear? Parles-tu français?"

Ink, his eyes lighting up slightly: "Oh, ces mots ! Je les ai compris ! Oui, je parle français !"

S!Papyrus: "Wait... Is that French?"

S!Sans: "Wowzers! Dad I didn't know you knew French!"

S!Gaster: "Oh yes, I learned it a long time ago for something special... I can't remember what it was. I just haven't used it in so long."

S!Sans: "Amazing! You're so worldly!"

S!Papyrus, folding arms and grumbling: "Why didn't you ever teach us French?"

I AIN'T GOING ANYWHERE WITH YOU UNLESS YOU PLAN ON TAKING ME HOME!

What? No, I can't. Your home doesn't exist anymore. Error destroyed it...

STARS, NO... PLEASE, DON'T...

Sorry, Sans...

Someone else needs your help right now...

Ink needs to be very careful to not forget to refill his vials, or else he might end up in the hands of curious scientists... ---

Subject SD017

a.k.a, "Ink"

How can this monster live without a soul?

Though he appears to be in a fallen down state, the skeleton can still wake and give mild responses to stimuli. He has not answered any questions.

black blood, recovering injury

The marks on his face and "tattoos" at first appear to be stains. Instead, they are tightly packed black crystals.

Although most of his body is made of magic, the "marks" and his tongue are physical matter. The tongue in particular appears to be a magically infused living organism, stained with the essence of SOUL traits. Including Determination...

The body appears to be in it's late 20s. How was it able to grow these crystal structures? What are their purpose? How is his body crystal, magic and flesh? Is he a homunculus?

DT staining?

The black blood doesn't dust.

I will attempt to inject the subject with some of the remaining DT to see if there is a response...
