When I first made Torel, I was already not happy with the results. It was sloppy, to say the least. As I updated everything, I decided to keep the Halloween color scheming of going throughout all the characters, and not just the themeing of them wearing masks to change forms.
First Hallowstale character getting updated art is Chara Dreemurr. While some things stayed the same, like the bow in their hair, the hairstyle, and locket, their outfit changed slightly in style and a lot in the color scheming.
The top left image is of Chara when they were still alive.
The top left is them as a phantom.
The two bottom pictures are chara as a corrupted phantom. I'm thinking of making this possible to attain in a particular route in my 'choose your own adventure' story for Hallowstale. I also didn't know which one I liked best. I'll decide when I get to that point of no return section.
I will also update the character art/info area with the new picture.
Knows at least one piece of secret information on everyone in the Underground. This is because he keeps communication with all the spiders in the Underground.

Has a journal for every entry. The rest of the pages are filled with outfit drawings, fabrics, and stich patterns.
Alphys made a mask with a false soul property to magical turn Metta into a monster. The yellow soul is the only non-monster soul that mimics the form of a monster soul, making it the perfect substitute monster soul. And because it isn't a monster soul, it doesn't cause any harm to an all human being, like Mettaton. The monster body just can't be made of flesh; it has to be made of metal and wiring.
One time, Metta brought him onto one of her shows. Despite the crowds overwhelming positive reviews, the one time everything became quiet when Napsta messed up a remix, she got terrible stage fright and thought everyone hated the performance and that they messed it up. She vowed to support Mettaton from a distance... away from the stage.

Random facts:
Is very Punk
Died during the last PoS skirmish.
Is now a phantom that haunts her old styling dummy to interact with the world around her.
The dummy appearance has warped due to M.D.'s angry soul.
Meet the Blook residence: Metta Blook, Napsta Blook, and Madelyn-Dummar Blook. All three are cousins. And they own a quaint little snail farm in the northern section of Waterfall. Well, I say cousins, but they act more like siblings. The Blook families were farmers way back, using their ghostly monster forms to bond on scarecrow dummies. Down here, in the Underground, though, there are no crows to scare. So they tend to keep the tradition alive by making and bonding to regular dummies, each one created with the Blook in mind.
Metta didn't fit in with the notion. Probably because she isn't a m-h, just a regular human. But that doesn't mean she didn't often feel like a ghost. Most of the rest of the Blook families ignored her, like she wasn't really even there, or forgot that she was there. The only one that would give her the time of day, was Madelyn-Dummar. MD taught Metta how to use her voice, but also how to be independent from an early age. As they grew up, Metta started to loose her ability to walk. No one could figure out why, and Metta's parents, as well as many of the Blooks, were staunchly against modern science. At least MD wasn't, and was at least able to sneak Metta in for tests and yearly vaccines. For the tests, it looked like Metta had some sort of bony atrophy that had no known cure. She just simply loss the ability to walk... permanently.
Not only was MD taking care of Metta, but the two pseudo adopted Napsta. Napsta was naturally quite and easily forgettable; a true ghost. Many of the other Blook residents kept forgetting about Napsta.
While not having any strong ties to Gerson, they still went to her monstercation ceremony to pay respects for her work as the founder of the Underground guard. Not like they had much of a choice anyways. More like, MD didn't have a choice. She was 10, and the family didn't forget or ignore her like her other two cousins. So while she had to go, she drug along 8-year-old Metta and 6-year-old Napsta along with her. If she has to suffer, so do they.
The moment MD turned 18, she officially adopted Metta and Napsta and they all moved out to a quaint melded three house apartment building.
When Metta was 19, she heard about Doctor Alphys, head of the science divisions. She heard he can perform miracles of technological advances. She also heard of a rumor that the head scientist may just be human. But that's impossible, right? In any case, human or monster-human, he could make her walk again. He could make her feel like herself. Metta took Napsta with her down to Alphys' private labs and demanded he make her walk again. As Al tried to reason with Metta and dodge any questions she threw at him, Napsta had turned into his ghost form and found Al's mask. With this piece of blackmail, Alphys' admitted to there being a way. With an agreement to keep quiet about Al's secret, he made Metta a mask that would give her a robot monster body, just like him, to her exact specifications.
Finally, Mettaton felt like herself. Mettaton... that rolls of the tongue nicely. With Mettaton's new body, she felt like she got her spark back. She started to do small performances at the Tartarus (The Core) Hotel under the pseudonym Mettaton, but soon started gaining overwhelming popularity. She became a big-time celebrity. She would soon buy the hotel, and rename it to Mettaton's suite. There, she would sell all Mettaton related merch, and redesign it with a fountain of Mettaton in the central lobby. The only problem with being as popular as Mettaton is, her new body can't quite keep up with the constant performances and demands. So she moved out! She would live with Al at his personal lab so he can perform routine check ups, maintenance, and so she can be closer to her line of work.
The event of Mettaton leaving pissed MD off so much. If Metta is just going to abandon her and Napsta, and cut all contact doing so, then fine! MD will cut all contact with Metta too.
The reality on Metta's end, though, is that she's just been busy. And after having so many missed calls from Napsta and MD lumped with missed calls from fans, Metta handed off all incoming call requests to one of her employees. Though, the employee doesn't seem to be good at her job. And with each passing day of not receiving a call from either of her cousins, Metta felt the guilt grow and shy away from making the first move.
Napsta had found a lot more free time now that they didn't have to take care of Metta anymore. He applied to join the Underground guards. And while his shy demeanor and lack of fighting prowess meant they weren't going to be on the front lines anytime soon, her abilities as a ghost made her the perfect security watch for in the Ruins. They got herself a little room for him to keep watch during their shift. And as a regular requirement, Napsta had to train in the case she did have to fight a PoS member in the future.
When MD was 24, Mettaton was 22, and Napsta was 20, there was a PoS raid. While all the new empty souled humans that fell down into the Underground were delt with by the guards, some who had waited in the Underground for years like this struck all around the Underground. Both the Underworld and Tartarus were protected with Alphys' and Mettaton's defenses and evacuation protocols. But Phantom falls didn't have any protection. In the process of evacuating and hiding Phantom falls residences, MD was struck down and killed by a PoS human. Luckily she managed to take the human with her to her grave. And through a combination of having a determination soul, anger, and unwillingness to move on, MD became a phantom. However, as a phantom, only those that connect to her soul -either by having a piece of their soul in another person's soul or by being related to the person now phantom- could see her. So, to interact with the rest of the world at large, she takes possession of her dummy to act as the medium.
Things stayed largely the same after that. Within the next 4 years, both Mettaton and Napsta Blook had moved on with their lives, and MD refused to do so. It became their normal. Unfortunately, one day, MD would keep Napsta from arriving to his shift due to troubles arising with Frisk when they fall down.
I went ahead and updated Gaster as I figure out commission prices. I will also be updating the post for Gaster's information page with these pictures and removing the old pictures.
I had made a post a while ago where I said I needed to draw Hallowstale Sanse with red eyelights and with the passion shaped eyelights. So I decided to do both! I imagine the scenario being something akin to being so determined and so passionate about their plan that both the flower and red eyelights happen at once.
Then, while I was fiddling around with the settings, I discovered this disturbing beauty!
OP seems to have classified it as a special case of halfnium, reclassified as a lanthanide. This has fascinating implications for electron orbital geometry.
I thought so, I took one look at your classification and immediately thought “this is definitely someone with a deep understanding of how the periodic table works”
I’m glad that we have reached a consensus on the expected elemental properties of milk
That would involve writing a crash course in how suborbitals work on a post about whether water (the primary ingredient in milk) is in milk and even for tumblr that’s going a bit far
MILK IS SEVERAL COMPOUNDS PLEASE YALL ARE KILLING ME OVER HERE
We have a container of dry milk because in addition to a little fat and sugars, it contains proteins, which settle into the pores of nitrocellulose membranes, making sure analytical proteins (specific antibodies) don’t get trapped. We could just use casein (one of the proteins in milk), but milk is much cheaper and can also be found at Walmart.
Enter OCEAN EYES and NOT DEAD YET, two of the king’s most quarrelsome stablehands.
OCEAN
May one explain what powdered milk doth be?
Is it not gas? I live in constant fear.
NOT DEAD
The water flees to air, the rest is left.
The dry debris then forms the powdered milk.
OCEAN
Thou sayest water doth reside in milk?
NOT DEAD
Pray tell what thou believ’st the liquid is?
OCEAN
Is milk not one pure substance in itself?
NOT DEAD
No; ‘tis only milk-stuff mixed with water.
OCEAN
Yet milk appears from living cows’ own tits!
NOT DEAD
‘Tis juice from tits, yet water still it holds.
If water be in juice, then ‘tis in milk.
Enter DERIN, the scarlet pescatarian.
DERIN
‘Tis drops of fat afloat in water,
As if ‘twas dressing for thy greens.
With water gone, the powdered milk remains.
A NOTE attached to an arrow, written by BURNING BRAND, flies through the window.
BURNING BRAND’S NOTE
Obsessed with he who foolishly believ’d
That milk is element of chemistry.
The NOTE crumbles to ash. BURNING BRAND is not seen again.
OCEAN
As he who instigated such a fight,
I felt that this creation was my duty.
OCEAN unrolls a scroll of parchment with a flourish.
OCEAN
Behold, ‘tis milk, one hundred and nineteen.
Enter JASON FUNDER BERKER, a frog.
JASON FUNDER BERKER
And yet the burning question still remains:
‘Tis metal, not, or somewhere in between?
JASON FUNDER BERKER does not wait to hear the answer, and exits.
DERIN
A lanthinide! A special case, I see.
How fascinating, geometrically.
But let us leave atomic musings be.
For milk is a rare metal of our Earth.
OCEAN
Of course it is, for I am always right.
My choices are, of course, deliberate.
DERIN
I do not doubt thou speakest truth, my lord
Thy brilliant mind is utterly unmatch’d.
It seems that an agreement has been reach’d.
OCEAN
Of course; however, in sincerity
I wish to know thy scholar-driven thoughts.
DERIN
I fear ‘twould be beyond thy comprehension.
To teach to thee would take this much too far.
Exit OCEAN, in a huff. Enter JESIN, BOOP BOOP, FLIPOCRITE, VELVET, and LOVELY DREAMS, curious onlookers attracted to the scene.
JESIN
Do teach us, it would not take this too far!
DERIN
Ye all complain of learning strangely,
Then ask me baiting questions such as this!
BOOP BOOP
Thy gross ineptitude shall be my death!
Milk is formed of small component parts.
The fat, the sugars, proteins all combine
They seep through pores of membranes in this drink
Unpleasant compounds all are filter’d out.
All this obtained for small amounts of coin.
DERIN
No, milk is lanthanide, pray keep the pace.
FLIPOCRITE
The word thou mean’st is lactanide, I think.
DERIN
May sharpened pain-shaped stones fill up thy shoes
So that thou never know’st a moment’s peace.
VELVET
A cube of milk, three inches on each side
Could blow up the entire galaxy.
DERIN
Our galaxy was formed in such a fashion.
‘Tis why we gave it name of “Milky Way.”
LOVELY DREAMS
Thus ends our entertainment for the night
Here fools and pompous scholars come to fight.
Exuent, pursued by a cow.
(Shakespearean adaptation format inspired by @mortimermcmirestinks in this post)
This is one of those threads that would go perfectly as a video set to “in the hall of the mountain king” and we all know it, I’m just not gonna be the one to make it

Random facts:
On the surface, he does have a sister. She's his twin, but she's not a monster-human. Due to the instilled fear and hatred to m-hs, she became the one to rat Papina out when she saved her from the bullies.
(NOTE: M.K. won't get any background info, just the general info up top. The background info is only for Undyne)
Undyne knew Torel's orphanage since he was a child. Which wasn't long. When he turned 5 and received his mask, his parents decided they wanted nothing to do with him. So, they took him to the barrier at The Hollow (New Home) and shoved him through with no intention to follow. Asgore quickly found him, and took care of him for a couple days before dropping him off at Torel's orphanage for displaced children. There he stayed for a couple years until he was about 7, when he would be adopted by Gerson.
Gerson was the original creator of the Underground Guard, with her as the head. But at his old age as a human coming to an end - and she will only get older still as a monster - Gerson figured he would need someone to take up the mantle soon enough. Gerson never thought to make Undyne captain. No, she adopted Undyne because she was drawn to his feistiness. It wouldn't be until Undyne started picking fights at school that Gerson would decide to train him for discipline; and only after seeing his bouts of strength and skill from only a little training did Gerson decide to train him to be the next captain.
Training Undyne was no easy feat. While discipline can be taught easily enough, having the disciplinee trust the discipliner is another. It wouldn't be until sometime after Gerson's monstercation ceremony that Undyne would trust Gerson completely.
On the day of the monstercation ceremony, Undyne wanted to escape. Seeing his mentor reach this new stage in his life, trapped down here, Undyne felt despair for the first time in his life. He hated this feeling. Luckily there was a nerd who also attended the ceremony, named Alphonso. Even his name sounded like a nerd's. Al would be much better! And the other kid seemed to agree considering he didn't object to the nickname, plus Al started using it himself!
Once Undyne trusted Gerson, he started taking his training more seriously. He even started to consider becoming, and maybe even leading, the Underground Guard. The only obstacle that stops Undyne from being captain is Asgore. Not saying that Asgore has a say in the matter, but that Undyne heard Gerson say that Asgore is the strongest out of everyone here in the Underground. And if Undyne can't beat Asgore in a fight, he feels like he personally wouldn't be fit to lead the Underground Guard. So, starting from age 9, every year on his birthday, Undyne would march up to Asgore's front doors and demand a battle with her. Asgore at first refused, but after recommendation from Gerson, and Undyne's stubborn refusal to back down on this one thing, Asgore finally caved. But she didn't fight immediately. And that frustrated Undyne immensely. Any time Undyne tried to land a blow, Asgore would dodge. This would become the next stage in Undyne's training.
As Undyne trained, he would often sleep at Asgore's place. He also joined the Underground guard for patrols. And as he trained for his position as captain, he became well acquainted with a secret comrade, Sanse, the judge that determines if someone should be allowed to visit Asgore or if they wish harm upon her. While on patrols, Undyne caught glimpses of Papina while on patrols in Phantom Falls. He saw how strong she was, how capable she is. One day, he offhandedly remarked how Papina would make an excellent guardsman, to himself of course but it just so happens that Sanse was around to hear that remark. Sanse offhandedly remarks that if anything were to happen to their sister, they would personally hunt down the one responsible for putting Papina in the situation to begin with, to themself of course; it just so happens that Undyne, and Undyne alone, was within earshot to hear it.
Undyne wouldn't be able to land a single hit on Asgore until around the age of 14. That is when Asgore incrementally increase the difficulty until she also fights at full strength. They also spar on the regular. It is at that point where Undyne managed to successfully beat her time after time after time at the age of 21. Undyne felt like he was finally ready to take on the mantle of captain of the Underground Guard.
A year later, when Undyne's 22, a hoard of empty souled PoS members purposefully fell into the Underground with the goal of wiping out the survivors. Luckily, they received word from Napsta about their arrival. And while the volunteers usually train for this kind of scenario, having a swift confirmation helps tremendously in placement. So much so that they were able to fend off the PoS at the gates of the Haunted Ruins. No innocence were harmed, only guardsmen. During that battle, one PoS member fought very recklessly. They managed to severely wound several guardsmen on their own, and when Undyne rushed to deal with them himself, they landed a lucky swing at his face, scaring and blinding his left eye. After the battle was over, Undyne personally helped carry those that had 'Fallen Down' to Alphys.
A couple nights later, after a celebratory party for the successful defense, Undyne was greeted at his door by none other than Papina. She started rambling Undyne's ear off about what the guard had accomplished, how cool they were, and that she wants to join! Undyne already knew what would happen if he let Papina join, and he was too tired. He refused Papina and shut the door in her face and headed off to bed. But to his surprise, he opened his door to go out for patrols and was greeted by an enthusiastic Papina, who had not slept a wink that night; yet she acts as if she had ample sleep the night before. That was enough to convince Undyne to take the risk and train Papina. However, Undyne would soon realize why Sanse made that threat: Paps was too nice. For as strong as she is, she doesn't seem willing to take the killing blow; she wouldn't even go for a mercy kill. For crying out loud, she managed to defeat Undyne easily on the first try! But whenever the topic of killing came up, Paps would try to find some work around. Undyne couldn't bring himself to accept her into the guard. So he kept making excuses as to why she shouldn't join, and divert her attention elsewhere, like cooking! It's a good thing Undyne's a terrible cook, because the longer he can take on teaching Papina something that isn't guardsman training, the more he doesn't have to come up with less and less convincing lies and excuses. Unfortunately, it got to the point where he had to accept her somewhere, so he set her up close to Sanse's base of operations: sentry duty.
It's a good thing Undyne trained Paps as well as he did, but it did very little when it came to defending the Underground from Frisk.
Next up is Mettaton, Madelyn-Dummar, and Napsta Blook
Grilby owns two homes: one in Halloween Town and another in an unnamed desert biome. Justin, Bravin, and Kindred live solely in the desert. Even with their jobs, they also own a farm where they grow all the best fresh produce for Grilby to use.
I gave up on the story
Something something Farmtale has Horror terrorize any locals and visitors on Halloween with their endless laberinths. This is one of his favourite jobs.
There’s that time of year in FarmTale for Halloween, every local offers up space in their vast crop fields, rearranging them into large, seemingly endless labyrinths. Many locals and visitors from many other AUs gather to dress up, roam the mazes, and scare anyone brave or dumb enough to take part and search for the Golden Egg: a macguffin, a prize of sorts. Rumor has it that whoever finds it is rewarded with a year’s worth of candy and crops, all made by the AU itself.
This is one of Horror’s favorite jobs. Always the first to greet those daring enough to enter the labyrinth, handing them a small light that will only last for about an hour. Once gone, you’re left alone in the immense fields, surrounded by total darkness.
And once the light is out, the hunt begins, it's up to you to find spots of refuel to have another 30 min to roam without being hunted otherwise every creature that roams freely within the labyrinth becomes aware of you. Finding the exit becomes an almost imposible deal, some who enter the labyrinths never leave at all.
2. Sugar Skull (my Sans from a Halloween themed AU) would be banned from this event because the first time they went and got their lantern, they started teleporting around until they found the egg.
A silly AU that takes place after the events of season 1 of Underverse. XGaster succeeded in his plans to create 1 universe. However, something went wrong and the universe consists of only Sanses, minus Frisk. There is no rhyme or reason to the characters the Sanses take over.
XGaster was shunted to the void, doomed to watch his failed creation.
Ink, Cross, and XChara all keep their memories.
Cross and XChara were sent far back to the beginning of time in the underground, becoming the first fallen and appearing as a ghost when Ink falls down.
Ink falls down with the Frisk of this universe. Ink also gains a rainbow soul, contained in a glass heart container, replacing his paints; as he travels through the underground with Frisk, he learns to control the different soul traits.
Even though Ink shares the protagonist spot, there are other versions of Ink in other roles.
The "story" of this world is relatively the same as Undertale: Monsters and humans lived in peace until humans waged war and locked the monsters in the underground. One key difference on the surface's end is that humans have mages; they remember the monsters they locked away, and so they train up mages to keep monsters trapped in the underground.
Characters:
Frisk-> Frisk & X-Event Ink (Rainbow)
Chara-> X-Event Chara & Cross
Toriel-> Altertale Sans (Alt)
Asgore-> Storyshift Sans (King Lazybones)
Sans-> Undertale Sans (Sans)
Papyrus-> Underswap Sans (Swap)
Undyne-> Fellswap-X Sans [by @fellswap-x] (Trigger)

Okay but guys consider a Danganronpa x Undertale AU
I call it Accusertale (because Ultimatetale and Trialtale are already a thing)
It’s literally Undertale if it was a Danganronpa esque situation
Everybody would be an Ultimate
Frisk might be a Reserve course student like Hajime is
Frisk
-Frisk as mentioned earlier would be in like a Hajime situation OR they would be the Ultimate Savior
Sans
-Ultimate Judge
Papyrus
-Ultimate Pacifist
Undyne
-Ultimate Guard
Alphys
-Ultimate Scientist
Mettaton
-Ultimate Robotic Sensation
Grillby
-Ultimate Bartender
Muffet
-Ultimate Baker
Gaster
-Ultimate Scientist
Nice Cream Guy
-no Ultimate
Burgerpants
-no Ultimate
Temmie
-Ultimate Shopkeeper
Monster Kid
-no Ultimate
Napstablook
-no Ultimate
Asriel
-Ultimate Prince
Chara
-Chara I’m not too sure yet but prob same situation as Frisk or an Ultimate
Flowey
-the Monokuma of the world
Toriel
-Ultimate Provider
Asgore
-Ultimate Ruler
-the Mastermind
The past of Undertale is still the same- the war, Monsters being locked away, etc..
Being an Ultimate is a title you receive, and it depicts you as the best in that category. Not every Monster is an Ultimate, but every Ultimate is a Monster.
After Chara died and Asriel disappeared (idk if that’s what happened to him I haven’t played the game) and Toriel went behind the door, Asgore began hosting secret “games” a human fell. Basically, a human and a random group of Monsters would be selected to participate in a “reality show” that is broadcasted throughout the Underground. The contestants really get blackmailed into killing each other and ultimately the human (everybody has to die because of word got out about what the king was doing it would end bad for him). After the human dies, any remaining contestants are killed off while the soul is collected.
The residents of the Underground are unaware of the deaths that are occurring. How? After dying and dusting, Asgore will come to collect the dust and then throw it into the void.
The characters listed above these paragraphs (save for Toriel, Chara, and Asriel) end up in this game. Like Danganronpa, everyone is given a motive, and the killing can begin.
I think that the survivors would include Sans, Frisk, Undyne, and Mettaton.
I’m not 100% sure who the Blackeneds would be, but for sure Burgerpants and Muffet.
Gaster takes a role like Kirigiri’s father.
Obviously not every single Undertale character is mentioned. These are just the ones that I can remember off of the top of my head atm, and I will add them in later.
Interrupting my usual Undertale related works for a Warframe comic, depicting Voruna thrashing around a Kuva Lich like a dog toy! A friend of mine asked me to make a picture, and I decided on a comic! Enjoy! The comic in full is right below if you'd like to see how they all fit together.
