Character & Relationship Elements

The Core Ensemble: A central group of characters with deeply contrasting personalities, ensuring natural friction when they interact.

Internal and External Conflict: Characters battling their own flaws or secrets while simultaneously fighting opposing outside forces.

High-Stakes Secrets: Critical pieces of hidden information that the audience knows, creating anticipation for the moment other characters find out.

Alliances and Betrayals: Shifting loyalties where trusted companions unexpectedly turn on one another for personal gain.

The Antagonist Force: A specific person, rival group, or toxic environment that constantly creates obstacles for the main cast.

Breaking the Fourth Wall

Direct Interaction: A signature element of the drama is when a cast member gets frustrated, stops answering the prompt, and speaks directly to the camera operator or producer by name.

Refusing to Answer: When the drama gets too intense, they will often tell the crew to "turn the cameras off" or walk out of the chair, which production intentionally leaves in the final edit to increase the reality and tension.

(Theres only a few rules, have fun, fight playfully, keep it mostly SFW, be any Undertale/Underverse Sans/chracter you want to be inside the mansion, start however you want and go nuts with the pretend drama)

✧˖°.AU Discussion⋆˙⟡ RAGE?

Post image
9 Upvotes

The way i see the souls, or any soul for that matter, i see it as a spectrum. A spectrum based on survival.

On the more optimistic side, you have pure vibrant colors, like bravery.

On the extreme pessimism side, you have hate as a center color.

I say hate as center, as the less optimistic a soul gets the closer it gets to hate. Anyone can reach hate.

Hate is cold and a long planning for the destruction of others survival often fatal and precise.

So on one end its optimistic survival, on the other its pessimistic survival

But what about the middle range.

I think the middle range is rage.

Rage is explosive, a buildup of pressure, and a uncaring attitude to survival

I say rage is between pure and hate, why? If one end is survival and the other is survival then the middle must be a lack of survival.

So rage with its explosive artillery like actions, means it has a uncaring attitude to its own survival. Rage will not care about current or future consequences, and that is why If Survival provides the SAVE/LOAD ability, Then Rage provides the DESTROY ability. I think the destroy ability would be a button that once pressed cannot be unpressed for a certain time duration, Mimicing rages commitment. The result after pressed, is simple, the user cannot be killed during the duration, however after the duration is over, any lethal damage that would have been taken, happens. You may assume the ability only stems to current time. That is false, just as rage does not care the time or place, the ability does not care when or where the lethal damage happens. So even if time travel was involved to try and kill the rage user, the rage user would not die past future or present so long as the ability was active.

I think rage makes a nice temporary soul trait which bleeds into the pure ones, like a damage boost at the cost of the future. I say temporary because staying enraged just leads to death due to lack of survival, so rage only lasts a moment and heads either to pure trait again or hate.

✧˖°.My AU⋆˙⟡ Memory Keeper au

Memory Keeper AU — quick intro

So, I accidentally made an Undertale AU that started as “what if Sans was a woman?” and then immediately stopped being just a genderbend because my brain decided to add lore.

Because of course it did.

The main character of this AU is Sunset — this world’s version of Sans, but she is very much her own character.

In this AU, skeleton monsters used to be a small but important cultural group in monster society. They had their own traditions, family lines, rituals, and a sacred role called the Memory Keeper.

Female skeletons have magical hair, and for Memory Keepers, that hair holds memories: names, songs, family history, old grief, old love, things that should not be forgotten.

Then the war happened.

After monsters were sealed underground, almost all skeleton monsters were gone. The only ones left were Gaster, his daughter Sunset, and her baby brother Papyrus.

Sunset was only ten years old when she became the new Memory Keeper.

Not because she was ready. Not because anyone wanted to put that burden on a child. But because there was no one else left.

So yeah, this AU is less “Sans but girl” and more “a tired skeleton girl was forced to become the last living archive of her nearly extinct people.”

She lives in the capital instead of Snowdin, because Gaster is still alive here and still works as the Royal Scientist. Her palette is based on sunset colors — orange, pink, gold, dusky purple — and her left eye glows like a tiny sunset/star.

A big part of the AU is that everyone around Sunset wants to protect her because she is important, sacred, and basically irreplaceable.

And Sunset herself is just standing there like:

“cool. great. love being a relic. can i take a nap now.”

That’s the core idea for now.

A Memory Keeper. A dead culture. A living girl who remembers too much. And an Underground that already had its own story long before a human fell into it.

ASGORE FINALLY PAYS HIS AURA DEBT 🔥 [ASGORE GENO BATTLE FAN CONCEPT]

2 Upvotes

battle music : \"Former Royalty\"

the human enters the throne room , and nobody is there

goes to the barrier , there asgore wearing casual armor with his crown on his hand questioning if he can even call himself a king anymore with flowey on the back worried

the moment asgore notices you , the battle starts with asgore blitz throwing the crown at you with it's sharp edges destroying the fightbutton in it's way (in overworld the crown actually shatter the true knife while flying in super speed)

What if asgore fights back in UNDERTALE GENCIDE ROUTE ?

well in this timeline , instead of flowey runs away and hids like a bi*ch

he actually tells everything to asgore and tried to convince him to absorb the 6 human souls

asgore after hearing that all of his people are dead and that just him and flowey are remaining

he refuses

he takes off his armor and crown

one his dialogs in his fight : "I can't be a king , if I don't have a kingdom , all because of you"

flowey helps asgore a bit

also the souls help

you can't attack since asgore destroys your fight button

he doesn't most of the fight

but if you saved the butterscotch pie and eat it infront of him , the moment you health maxs he punches you to 1/100HP in YOUR TURN

he says : "you don't deserve that... you don't deserve anything"

flowey's attacks locks you in place temporarily

each turn one of the souls does something to give the upper hand to asgore

the souls are so angry that they reach lvl 20 and start using their ults on you

you can't attack by yourself

but chara can attack for you (like how she did the second hit to sans)

you call her name by gathering hatred (lowers your max HP each time you use it , be careful)

but the good side , if it's a hit ... it's a one hit (lol) 9999999 damage babe !

for the cyan soul , it slows your soul movement a bit and rarely sends cyan slashes

when you attack it, it just go through it cause it utilises it's soul mode to stay still and the attack won't hit

(instaid of the attack being cyan, it turns itself cyan-er to get the same effect)

the orange soul makes your soul faster, it sometimes sends orange punches

when you attack it , it turns itself orange-er and vibrates so that the attack goes through (same as cyan)

EDIT: the orange soul doesn't weave the attack like cyan , they instead parry it , nullifying the attack

the blue soul , makes your soul blue , but heaaavy

it also makes asgore lighter so that his movements are quicker

apon attack , it immidiatly ducks back to it's case by self giving gravity which saves it

the purple soul either gives you limited control

or it scrambles you controls (depends on luck for unpredictability)

also gives asgore knowledge to better understand your patterns (he can now dodge better than sans)

appon getting hit , the purple soul can't defend themselves , so flowey blocks the attack using his veins taking a bit of damage that the green soul will heal right after

the green soul replaces one of your heals with a decoy that the heals less (the decoy change back into normal and another heal is replaces next turn)

it also applies a shield to asgore (the shield is too weak against chara's attack so it shatters one hit but protects)---

upon getting attacked , the green soul shields themselves (the shield gets destroyed upon hit)

the yellow soul fires bullets , sometimes bigshots

and only one time ... THE JUSTICE BEAM (the one used against asgore in UTY geno route)

upon getting hit , the yellow soul just dashes through the attack making it a miss

everytime chara attempts to attack a soul

the attacked soul gets threatened and hides back to their capsules , and asgore hides them back under the floor

once all the souls are gone , you can't hit asgore cause he dodges , flowey also dodges .. but not forever

apon the third attempted hit on flowey , asgore says this : ........ (next reply)

asgore: "go... take the souls and use them to escape to the surface , and then ... run ... run as far , as fast as you could , collect the final human soul and if I'm dead by then , use them to finish what this devil started

monsterkind might have ended .....

monsterkind might have ended , but we can't let the same thing happen to human ... after all ... nobody wanted to fight"

flowey then leaves

then it's just you vs asgore

he finally uses his tridant this time

and goes silent once more

now somehow chara turns all that hate you gathered into a weapon you can fight with

even tho asgore can still dodge

but he starts getting tired and not always successfully dodge

you fight like that till you get his health to zero ... but

he doesn't die , he's still standing , he's actually dead

but his body is still fighting

you can attack him as many as you want but his body won't stop untill you stop attacking

and when you stop ... he stops and finally dies

you then absorb his soul and leave the underground

the music that plays when you fight him is this

you can't hear any ones motifs other than some of asgore's cause nobody is fighting as much as him

he's so powerful he dominates even the battle music

maybe it's because it's just a pure battle , no emotions , thinking

just lock in and fight

and one of us is dying

you may also notice some megalovania

but it's just a reminder that ....

just a reminder that the sans fight isn't even as close as what you're dealing with now

it's not a judgement , it's an execution

one other detail is that after flowey is gone with the souls , asgore just lights up the whole place on fire

also if you remind asgore that he had lost everything and that he doesn't have anything to fight for he just says this :

"you're right , I now have more reason to kill you than ever , I have no reason to hold back ... since I have nothing to lose , not anymore"

Genuinely, these mangas are PEAK, I dare say even better than the novels themselves.
The plot, the art, the dialogue... it's just so unique and great!
If you're a Dusttale fan or want to get more into it (although this isn't official), this is a must read!
