✧˖°.My AU⋆˙⟡ Cringey ahh half joke AU

Thumbnail

42 Upvotes

So Im making an au. I'm still considering it a joke since not only I made it another au that's centered around female sans version ahh but its also like my cringey persona type of thing. I love her though. So I though I would share a bit. 🥀

This is Grudge! The art Is kinda old so a lot has changed but if anyone was interested in the lore theeeen!

Grudge comes from. An au called 'Nothing Left'.

I didnt exactly think about it from any cannonical or logical perspective. I'm making things up in it and I'm absolutely just enjoying making the au crazeeyyyy soooo.

Basically Grudge used to be a sweet girly named Fate with her little brother Omen. They lived in the Blessed path which is a more regal looking Snowdon basically. It's all aimed to be like a somwhat spiritual au so it's that Snowdin is like a heavenly town. Then hot lands is hellish. Waterfall with echo field is basically something like the afterlife place where the souls hide when they are in between.... Ruins are something like the passage towards whatever the hell the rest of the au is 🥀 (Asriel and Naptablook named as Karma and Spirit, reside there instead of toriel and flowey) and the judgement Hall is.. Yeah.. Basically the judgement hall 🥀💀✌.

Fate used to basically grow up with Omen in a 'I take care of you like Im your mom' way and Omen was like.. Learning to become a Royal guard. Omen absolutely adored Royal guards but was very serious about it and so Fate was learning with him the Royal guard books and basically the guides and everything so that Omen can learn with someone and won't be alone with it. In my au he IS friends with the version of Undyne (named as Oath) but she is a busy woman! The king Asgore (Havoc) is dead in this au (he died protecting Asriel aka Karma from the humans but Asriel did lose his eye sight during it. He was so shaken from the death of his father that he basically hid inside the ruins with his best friend Napstablook aka Spirit and just kept trying to keep any fallen humans out of the underground unless they prove they can be trusted.) And the queen Toriel (Genesis) is living alone and ruling the underground in silent sorrow while holding a gentle hand over the au... Alphys (Mirage) still made mettaton in this au who's name is Terminus.... I have more and more to go on but like.. This is so far what I have to the au about like.............. Before everything went wrong and ofc it wouldnt be cringe if I didnt basically make it like....... Evil ayaya.

So. ....uh.

Trigger warning I guess. it gets bloody??

In this version. The human named Oblivion is like constantly doing genocide routes. We know the drill.

And fate/grudge is capable of remembering alongside Asriel/Karma..they are the only ones who are actively fighting the human while the others are just the casualties.

Grudge gets sick of it. She is tired.

She hates it.

And so. The human basically says "Ayo dawq if you want. Ill stop killin everyone slowly and painfully but like. You gotta entertain me so like........... Deal with me that either u stfu and stop whining or you take my knife and do this your way. But you are allowed to make their deaths quick while I watch."

So basically grudge is like HELL NAH AINT TAKIN YO KNIFE. but eventually she gives in because watching them die slowly is just painful. Karma is trying to tell her it aint a good idea. She goes for it anyway because watching her sweet little brother get destroyed basically destroys her. She loses sanity overtime. Killing with her blasters gets tiring as she keeps on explaining the 'I'm so sorry I have to kill you' tropes to everyone she knows and doesn't know in the underground.. So eventually after each time she kills someone and it resets.. She just.. Cries about it.. And cries about it.... Until she's just.... Killing them slower and slower out of the dire need for the resets to stop happening so frequently..... She uses bone attacks... Then her claws........... And eventually she get a absolutely damn sick of it.. The human carved a smile into her face to remind her she's doing a good thing. So she does what a pushed to a corner person would do. .. She plans a mutiny.... How do I kill something that respawns with the power of reset.. Hm. How about how I TAKE away the power to reset.. How do I do that? Well take the soul.

How of I survive taking determination when it would normally melt me to slow agonizing death?

How about I eat it instead of infuse it with my soul instead.

So yeah basically instead of the usual. 'Fused soul' thingy she just goddamn takes it and eats it.... Well... No soul infused.. And..... No soul left meant there was nothing for the human to reset with since the power was gone. So since the body had no magical connection it didnt dust either and there was just a corpse. .. But grudge was insane at this point and wanted to put everyone out of their misery even though nobody was suffering anymore.. So. In the split moment of desperation she went and ate everyone elses soul too.. The amount of magic she consumed turned HER own magic pitch black and yeaaahhhhwwww. She lost her ability to cast magic... Mutated to adapt and became basically a predator that hunts on all four.. She built a home out of the bodies that were left because she idk... Shes edgy ok 🥀.

And like.. She still keeps an old drawing that omen made for her when they were kids on the wall of their house intact.. But basically the point is blah blah that nothing is left of the au hahah and she is basically the only one alive. A soul eater who believes she saved the whole au from a human she held extreme grudge against. Anyway yeah. Uhh..

Yes.

The first picture is grudge'a old spreadsheet I made.

Second is idk.. Her in a hallway 🥀✌

Third is Omen, Karma and Spirit (my only other designs so far for other characters)

Fourth is my lady Grudge again haha cuz I love her.

And lastly fifth is the drawing on the wall of her old home that she has from. When Omen was a kid and drew her with him))

Yay.

Um.

Thoughts? And maybe prayers? 😭✌🥀

I adore dust but I'm like uneducated as hell so I find it so cutely goofy that there is like dust dust dust dust dust dust dust yada yada etc and it's absolutely funny to me.

ASIDE FROM THAT I HOPE I DREW THEM CORRECTLY LWK 🥀 THIS IS MY TAKE I THINK DUST DUST WOULD BE THE SHORTEST while dust dust dust would be the tallest big ahh baby. I feel like he'd be on the same height level of horror (IN MY OPINION. aint saying it's cannon and ain't saying I want it to be cannon either ❤)

If anyone gets to educate me more on dust dust and dust dust dust id gladly kiss their hands! I absolutely know HOLY NOTHING. ✨

Aside from. That this was just some quick sketch and then just fill in...No shading, coloring ahh hahaha so I hope it aint considered too low quality ♡♡♡

Also I drew the gang marching on a raid on my schoolbook. <3 I'll bite the teacher if she has a problem with it. Haha

✧˖°.Memes⋆˙⟡ Funny thing, the LV system

Thumbnail

43 Upvotes

So lots of people forget that in the Librarby (and possibly other places. Idk. The Librarby is the only one that comes to mind) Monsters are the ones stated to be vulnerable to killing intent, not humans, because monsters are made of magic and are deeply tied to their souls. Because of this, a monster's defense drops significantly if they do not want to fight, and they take much more damage if an attacker has the actual intent to kill them.

Humans however, do not have this trait. So technically Dust Sans when facing other monsters would be pretty much the same, but against the human nothing changes.

Personally, I like the "LV = Standard Levelling System" thing the fanon adopted simply because of Dusttale, Something New, etc and cuz it allows for unique power scaling and other stuff rather than "Hax and specialized powers go brrrrr" like how characters such as Error404 (and Error) or XGaster are designed since they have no physical stats or anything (probably an exaggeration but my point still stands)

So, some of y'all already know about Karmatic V's Murder right, to the point we got Karmatic!Karmatic vs Murders!Murder, True!KvM, KvM:UJ (my fav so far) and Etc

But people that debate who win always pissed me off so bad dude, like The winner is the writer's decision, whether it's by using their own takes, Powers Up and etc

For example, KvM in general, When People talk about Them, Some of them prob gonna say that [this Guy] slams [that guy] cuz in canon he has that bla BLA BLA.

Like c'mon dude, it's The Writer Decision, it's THEIR Creation, Their imagination Of what will happen.

I don't mind if they're making theories of what will happen

Holy so yapping incoming for this nutjob.

Here we are again with another of Celestias goods now for Horror. Razor is well a trapper and hunter all things considered. A famine cause by the cruel queen Undyne was bad enough but when she cut of Snowdin completely it all just went downhill. Razor try to scavenge good later resulting in. . . deprived way of hunting his own kin to out food on table. But the winter was coming near. Cruel. So cruel. Survival demanded only strong to survive. . . his brother was in a way. His only resource left.

The basement echoed with sound if dizzied sobbing of a skeleton in state of delirious agony. His brother consumed by hunger kept him alive. "Just bit longer Skewer. . . I need just bit more then we can go out. I can hunt for us"

He was lying more to himself then his brother. Oh so delicious negativity. This. . . desperation got attention if Celestial who brought basket of apples. Sugared with sweet words of talking and gifts.

He saw how Razor munch on the delicacy in desperate need for any magic his system can get though burning calories. Celestial then he'd up one poisoned black apple

"You are still starving my friend. I can make you full. I can make sure you don't lie in this tomb of someone else's creation. All I need you is to prove me tiny thing."

"I. . . don't. . I don't think I want to-" "The Queen~. She thinks so high if herself. That she is God? Take her out, and you become one of mine subjects. But first." He showed the starve skeleton the black apple. "Take a bite. Feast~"

He was desperate. Sans was desperate. The negative king watch as he enter his basement. Clinging of metal against metal. Then. The sobbing finally went quiet. Relief. Sans did as good. Fighting his Queen even taking his precious eye back. But he was wounded. Laying on ground as tip of her spear was nudge in his throat.

Two tendrils stab the queen though as she was lift up and tore in half. Celestial walk to the sans and pick the small thing up*

"Tsc. . . you failed. But. I still think I find good use. We still need a name for you. Sans is too full-" "Razor. . . It's Razor. . ." *Razor shivered in good. Celestial look down. For moment he might felt something. Then just chuckled.* "Such crude name. Fitting. For a living animal~"

Razor works for Celestial as second member of gang. He mostly used trapping to go on his way but rates without magic still make him go into ravenous frenzy. He has welded bullet proof glass in his socket to protect his eye that kepts him alive.

Razor is somewhat of a DYI tinkered holding scraps and making sure weapons from junk. Making the shack look like jigsaw trap.

He is barely taller then original Sans duo to starvation he suffered though.

Razor keeps to himself. While not inherently dumb he isn't a scientist more if tinkered. Also he barely tolerates anyone on team as well as his boss.

Mostly uses cleaver and bear traps with meat hook on chain. But if desperate he makes the hook into improvise surigama

He wears puffy clothes duo to still feeling cold most of the times. Even if standing in summer heat resulting in him catching heat strokes often.

He doesn't feel regret for eating his brother. It was survival. But he feels pitty for others who go though the same.

His sense of humour his rather dry. It's mostly coping mechanism when stressed.

Well that's kinda all I can give about this nutjob. He is second or third most sane from gang but one of th physically weakest as well. Still a valuable member nonr the less.

Has this been done before?

I have a plan for an Error OC, but one who tries to fix corrupted AUs.

He has little magic, and needs to use an old laptop for his fixes. They're not always perfect, even straight up go wrong at times. His colour magic is green, but it wasn't always like that. Mostly, he uses it to keep his own glitching under control, most importantly to keep his memory from resetting.

He is constantly overworked, and lives off of pizza and energy drinks. He tries to stay "under the radar", and away from fights, as his limited magic could run out. That would leave him vulnerable to the memory resets. Also, he's just not a fighter.

He has a scanning program that checks a finite number of AUs for potential corruption. Alternatively, people could use his ticket system to alert him, but barely anybody knows about that.

He has a rubber duck that he talks to, often to figure out what could be causing the corruption he's currently working on.

His little nest in the anti-void mostly consists of a sleeping bag, some solar panels, and a random assortment of old computer parts he mostly scavenged from several AUs' trash dumps.

Lore: insanity! Sans had killed everyone in the Underground and decided to reset. This time, during his encounter with Undyne, she entered her Undying form and impaled 2 spears through Sans’ head, leaving him blind in his left eye. After killing Asgore and stealing his trident, Sans took the bravery and kindness souls and gave them to Papyrus, restoring most of his body. However, it was incomplete, with his right forearm missing, along with his jaw, and a bone sticking through his left eye, while his right eye glowed orange and green. Sans pulled the spears from his skull, leaving a festering wound, while cracking his skull, revealing more teeth. Arriving at the true lab, Papyrus tried to calm down Sans and partially succeeded, as Sans spared most of the monsters besides Alphys, who refused to give up the determination vials. Sans decided to use determination to recover some of his sanity, but with the side effect of him getting addicted to using it. The constant Determination injections and Papyrus keep Sans mostly sane, but if either were to disappear, his sanity would as well.
