[superbfirnacho]

Okay so i havent drawn them yet, but i have this character that was a warrior that fought during Monsters vs Humans (They're a Human)

and they met gaster during this, becoming friends. Due to this they were banished with the monsters due to it being illegal

So yea its OC x Canon, Their name is Magnolia / Nolia and are around the age of 25 after banishment Looks like this but with more colors, i overall wanna see how you design magnolia

(Magnolia x Gaster)

(I didn’t know if youd want romantic or platonic.) but I hope you like it. I had a fun time drawing Magnolia!

Timeless AU Sans and Asriel! 🫡

I was going to color them but I'm mildly afraid my roommate will come back and I am not about to try and explain... this. So, temporarily take these sketches!

With a bonus full-family wip! (I need to make Gaster smaller/thinner but y'know--)

In this au, Gaster isn't killed in the core accident, and so he's present for the major tragedies that would normally follow his death. And subsequently is able to fix some of the problems! One being Asriel's death and transformation into Flowey.

Gaster, who was working on making a monster from almost scratch (his soul was too weak to form another soul but he wanted a kid and yadda yadda), successfully created Sans. After a bit of studying Sans' growth, Gaster was practically able to revive Asriel. Asriel is older than Sans by a few years as his 'death' made him miss a few.

And during this process, Gaster also managed to rizz up Asgore by complete accident. They'd always been close, even before the war, but Asgore was to be king, and he was already betroathed to Tori at birth, so Gaster was content being by Asgore's side as a friend. Buttttttt Toriel leaving for the ruins in her grief left the door wide-open for Asgore to finally make a move on Gaster. They never officially marry, but literally everyone outside the ruins is aware that the two are together.

Asriel remembers very little of his death, but he remembers Chara, and he remembers the surface. Asgore and Gaster don't hide the fact that Asriel died from him, and one day Azzy got up the courage to ask Gaster if he could bring back Chara too. Gaster hadn't even thought about it, but he figured that without Chara's body he wouldn't be able to revive them in any meaningful way. Azzy doesn't give up hope, but he doesn't bother Gaster about it anymore.

Azzy is a gentle soul, shy and playful. He's not used to being an older sibling, and he misses his mom, but he likes his new family too. He often trips and falls, resulting in the bandaid scattered on his body, and he loves to farm just like Asgore, so he usually wears overalls.

Sans is Gaster's oldest son by magic-line. He's punny, a prankster, and the more confident between himself and Asriel. If they're out of their element, Sans is the one to forge through the path and laugh while doing it! Gaster can't get him to wear shoes ("You and Dad and Azzy don't, so why should I?" Is usually his rebuttle. No one can really argue it.) So he's usually seen only wearing socks.

Papyrus (who is only a few scribbles in Gaster's arms rn) is the youngest and doesn't really get the same chances as Sans and Azzy do as older kids, but he'll grow to be the most rambunctious of all of them. I think Papy is self-conscious when he's young (what if he's not good enough? Sans is so good at science stuff like Papa, and Asriel is a great prince like Dad, so where does that leave him?) But he ends up training in combat with Asriel before meeting Undyne and deciding he wants to be part of the royal guard! (That way he can protect his 1 hp brother and his Princely brother!) Undyne and him are quick friends.

Actually, since I'm on a role: Asriel keeps studying and learning from his dad on how to be a prince. Honestly, he likes what Sans and his Pops are up to a lot more, but he doesn't mind being Future King. (He sneaks into the lab to watch the two do their studies whenever he can.) Meanwhile Sans works with Gaster in the labs! He's a fast learner and loves the work, but everyone can see just how much more natural he is with social science. He understands the political theory Asriel tells him and Sans can dissect exactly wtf it means and why Asriel has to react the way he does. Sans still ends up being the Judge, but largely keeps his focuses to the Lab with his pops abd Alphys. And Papy is certainly Great. He ends up as co-captain of the Royal Guard. He's not quite as personable as Undyne, but he sure is committed, and has direct ties to the royal family. More often than not, when he's not doing his rounds or helping with training, he's Azzy's personal guard.

And yes, this does mean incoming 20-ish Asriel, 19-ish Sans, and 17-ish Paps designs are incoming eventually! Asgore and Gaster get to see their sons grow up!!!

SeasonTale - Prologue

It's finally here! For those of you who wanted more SeasonTale... I'm finally starting the story!

Here we go!

“This isn’t a good idea.” 

“And why do you think that?” 

“According to my calculations, the two princes will fight for power once they are older. This will lead to a division in your plan.” 

“Perhaps, but they are both my sons.” 

“Which alone is impossible. I don’t understand how you had two.” 

“Well, I did, and both seem equally worthy of becoming my assassin servant.” 

“One of them will rebel.” 

“If you’re so smart, tell me what to do with the other!” 

“You could give a child to the scientist.” 

A long moment of silence past between the conversers as a new creature joined their conversation. 

“I experiment on monsters, it wouldn’t be a good idea to give him to me.” 

“A prince should not be treated to such a pathetic life.” 

“Rude.” 

“But he doesn’t have to know that he was ever a prince.” 

“That’s impossible. Their eyes will show that they are related.” 

“Not if you changed them with magic.” 

The Gasters floated silently as they observed the third. They pondered what the stranger said. 

“Shouldn’t you keep them separated anyway? So they don’t find each other and rebel?” 

“We’ve already taken care of the other two children, surely they won’t find each other.” 

“It’d be devastating to our plan if they somehow did all meet.” 

“Exactly. So, change one of the other’s eyelids with magic and send him with the scientist. Your plan will be flawless with them never meeting each other.” 

“But the bond of brotherhood is so strong-” 

“Do as he says. Take the smaller one as your son. I wanted him less anyway.” 

“I am not a father. I conduct experiments, and I’m about to enter a new project with the spring kingdom’s Gaster by testing my subjects with magic!” 

“Who says the child can’t be one of the subjects?” 

A grin appeared on the scientist's face. He rubbed his hands together. “You, sir, are a smart lad.” 

“I try.” 

“My son will become a prince that everyone fears. He will become a heartless killer. I already see it in him.” 

“If he refuses?” 

“He doesn’t have a choice. I’m sure you’ll make sure of that?” 

“Of course. None of the children have a choice in what happens to them anyway.” 

“But if they find the rebellion?” 

The king snapped a deadly look at the scientist, his eyes lighting up. “Solstice will never find the children, let alone bring them together. I see no flaw in our plan.” 

“But-” 

“You dare question your leader? I’m sure he has the rebellion taken care of.” 

“Take the small Sans, I no longer need him. Make sure to keep him far away from the other kingdoms. And watch the other children from afar.” 

“Yes sire.” 

The scientist scooped up the former prince into his arms and darted off. 

“Do you believe that this plan will work?” 

“Indeed, old friend.” He smiled wickedly. “Soon, you will have four connected AUs ready for your command.”

The stranger floated and nodded silently, smiling to himself. 

“I look forward to it.”

Chapter Fifteen: Familial Complications

Tw: Minor child abuse

This takes place roughly three days after the previous chapter.

Sans sits on his bed, reading through a book on celestial bodies he had found in the dump a week prior. The book was of human origin, having fallen down from the surface. Sans admittedly had always had a fascination with space, and the stars above, despite never seeing them for himself. He had been glued to the book for the past half hour, and just continued to read.

Eventually, Sans gets bored. He bookmarks the page and closes the book, stretching his arms upwards momentarily, he proceeds to place the book on his nightstand, directly next to a picture of Chara.

Sans picks up the small picture frame, laying down with his head propped up on his pillow, admiring his beloved Chara. When the picture had been taken (only three weeks ago), Chara had just returned from their first proper date with him, still wearing their beautiful black dress.

Sans can’t help but smile and blush, “they looked so beautiful in that. Still can’t believe they’re officially mine” he almost-pridefully thought to himself.

Sans places the picture back down, his mind now preoccupied with thoughts of Chara. His thoughts were short lived however, because he was suddenly interrupted by a yell from downstairs.

“Sans! Get your ass down here, now!” His father barked.

Sans sits up, letting out a loud sigh and an angry growl. “Can’t I have a moment of fucking peace for once?!” He says to himself. Sans teleports downstairs in front of the couch, there he sees his father looking incredibly irritated, his right hand scrunched against his skull.

“Oh, THERE you are.” Gaster bites, roughly grabbing Sans by the shoulder. “Your brainless brother ran off a bit ago and he’s nowhere to be seen.”

“Papyrus?!” Sans responds in disbelief “how?” He asks.

“I was in the lab in the basement for a measly two hours. Two fucking hours, unsupervised and he ran off.” Gaster answered.

“He’s FIVE!” Sans retorted, angrier than ever.

“I sincerely would’ve thought that a five year old, especially one of mine, would be mature enough to sit still for two whole hours.” Gaster responded, dismissive of Sans' claim. “I don’t know why you’re trying to pin this on me.”

“Because it’s your fault! It’s your fault with your shit parenting that this ever happened in the first place! He’s a toddler! He’s YOUR responsibility!” Sans angrily yells, pushing his father off of him. “And I don’t know how delusional you’d have to be in order to-“

“SILENCE!” Gaster yells, cutting Sans off. He grabs his son with blue magic and slams him into the ground, holding him there. “Don’t you DARE fucking talk back to me, especially blatantly insulting me!”

Sans grunts in pain, desperately trying to pull himself up, to no avail. He resorts to teleporting out of the blue Magic’s effects. Now standing a couple meters away from where he previously stood.

“Resourceful yet.” Gaster states dismissively, shrugging. “Now, he’s somewhere out in Snowdin, go and find him.” He says, turning away and waving his hand toward the door.

“Wha-? You’re not going to look yourself? Or even help?” Sans asks, somehow shocked yet completely unsurprised at the same time.

“No, I’ve got an important experiment to run.” Gaster replies walking away.

“More important than your own fucking son?!”

“Do I need to repeat myself about the back talk?” Gaster asks, turning to completely face Sans, pointing his finger to the door, as his eyes turn completely black, “GO. FIND. HIM.”

Without a word, Sans teleports outside the house, pulling his hood up. Sans walks and walks, seemingly endlessly—constantly mumbling to himself about his hatred for his father and pondering the whereabouts of his brother—not finding a trace, even after what felt like an hour.

Eventually, he hears a familiar voice, not the one he was looking for, but a helpful one nonetheless.

“Hey, Sans!” They voice called out.

Sans turned to face Jackie clinging onto a tree. “Hey, Jackie. Mind lending a hand?”

“Looking for your brother?” Jackie asked, jumping down from the tree and walking up to Sans.

“Yeah, actually. Have you seen him?” Sans asks. Jackie may not be his brother, but having a member of the best trackers in the underground on his side was more than he could ask for.

“I have in fact, last I saw him, Dr. Gaster had just teleported him back home. That was about fifty minutes ago.” Jackie responds.

“Wait. Dad… brought him home? FIFTY minutes ago?!” Sans asks in disbelief. He checks the time, he’s been searching for around fifty minutes as well. “I…” Sans starts, anger slowly building up inside him.

“I’m guessing that bastard didn’t tell you that?”Jackie asks, placing a comforting hand on Sans' shoulder.

“No, in fact: he specifically told me he WASN’T going to look for him.” Sans replies, his eyes momentarily turning completely black. Sans pauses, taking a deep breath.

Jackie almost laughs, “and I thought MY dad was bad, holy shit.” He says, trailing his hand through his hair.

“You don’t know the half of it.” Sans replies, shaking his head and covering his eyes with his arm. “How did you know I was searching for my brother anyway?” He asks.

“Oh, I heard you mumbling to yourself about it.” Jackie replies, “I’ve just been chilling in and out of the woods here for the past hour or two, I had just returned when I heard you mumbling in the distance, curious, I investigated.”

“Fair enough.” Sans replied. “At any rate, I should probably head home now, I’ve certainly got some words for my father.”

“Yeah, good idea. I should probably return to my home as well. Funny, because I specifically came out here to get away from them.” Jackie chuckles to himself. “Oh, and- Sans?”

“Uh, yeah?”

“I was at the palace yesterday, and it turns out, Chara has a handmade plush of you that they apparently sleep with and cuddle constantly.” Jackie says smiling and chuckling to himself. “Don’t tell them I said that, though.” He adds, winking.

Sans blushes “W- wait, r-really?”

“Yup. Not only did I see it with my own two eyes, but his highness told me all about it. All I’m saying, is that they must REALLY love you.”

“They do, trust me. And I love them back all the same.” Sans says.

“Alright, imma head home, see ya!” Jackie says, before dashing into the distance.

Sans teleports back home, directly into the kitchen, there he sees Gaster and Papyrus at the table preparing dinner.

Papyrus, upon seeing Sans, runs up to him, and wraps his arms around his waist in a hug. “Brother's home!” He exclaims.

Sans returns the hug, before resting his hand on top of Papyrus’s skull. “That I am.” Sans replies.

Papyrus, let’s go and heads back to the table, Sans makes eye contact with Gaster, giving him a death glare.

“What?” Gaster asks, pretending to be innocent.

“You said that you weren’t going to search for him because you had an experiment to run, and that I had to go hunt him down myself. Only for you to go to him pretty much immediately after I left and bring him home without telling me. WHY?” Sans asks angrily.

Gaster laughs. “Oh, Sans. I didn’t lie, my experiment was testing the new underground smart surveillance system and its effectiveness for finding targets. It just so happens that Papyrus happened to run off on the perfect day to test it. You acted as the control group, to see how long it would take to find someone without the use of the system, and your pathetic ass couldn’t even find a single clue! To me, that’s a successful test, proving its capability, and prompting for wide implementation.” He says, condescendingly.

Sans stays silent, pulling up a chair and sitting down.

——————

Two hours later, after eating dinner, Sans sits in his room on his phone, eventually deciding to text Chara. {

Sans: “hey sweetheart”

Chara: “Hi, Sans! :D”

Chara: “How are you?”

Sans: “not so great”

Chara: “Oh… :( What happened?”

Sans: “earlier father called me down saying that papyrus had gone missing”

Sans: “turns out father had left him unsupervised for two hours and he got out.”

Chara: “Oh, no! Is Papyrus okay!?”

Sans: “yeah, he’s fine”

Sans: “after an argument about his bad parenting leading to him throwing me to the ground, he said that i had to go and find him and that he had to stay back to ‘work on an important experiment’”

Chara: “That’s awful! D: Did he hurt you?!”

Sans: “no lasting damage, just temporary pain”

Sans: “when i went searchin i didn’t find anything”

Sans: “but i did eventually run into jackie who told me that he saw dad teleport papyrus home a while ago”

Chara: “Wait, what?! So he just sent you out there for no reason?!”

Sans: “when i got back I saw him and papyrus preparing dinner”

Sans: “turns out his ‘experiment’ was testing out the new smart surveillance system to see how fast it can find someone”

Sans: “papyrus had just happened to wander off earlier and father took the advantage”

Chara: “That’s cruel! Why did he still make you go out then?”

Sans: “he says that it was to compare physically searching for someone, to doing so with the security system”

Sans: “however i'm convinced that his sadistic self also did it just to watch me suffer”

Chara: “What a jerk! :(”

Sans: “i hate him so fucking much”

Sans: “he doesn’t love me or papyrus, he only gives a fuck about himself. everyone below him is just a toy in his eyes”

Sans: “he’s such a piece of shit and i can’t stand living with him. he’s hurt me more than anyone could ever know”

Chara: “I know, Sans. I understand. It’s okay.”

Sans: “i’m sorry for swearing so much and the sudden rant”

Chara: “It's okay, Sans! I’m glad you got it off your chest!”

Sans: “thank you”

Chara: “No problem! <3 Love you!”

Sans: “love you too”

Chara: “Hey, I’m alone in my room right now, if you need a kiss, feel free to stop by! Just be quiet.”

}

Upon seeing that last message Sans wastes no time, and teleports himself into Chara's room. The room is dark with their face being only illuminated by the light from their phone.

Chara looks up to meet Sans' eyes, their expression quickly turns to a cordial smile, as they wave their hand toward themselves, motioning him to come closer.

Sans obeys, walking over next to them, taking note of the plush next to them (he’ll make sure to lightheartedly tease them for that later). Once within range, Sans leans in for the kiss.

Chara plants a kiss directly on his teeth, following up with a hug, “I love you, Sans” they whisper ever so quietly.

Sans leans back a bit, placing a nip on their cheek in response, “I love you too, Sweetheart.”

Author’s notes:

Yes, my Gaster is an unapologetic villain, and no, he will not change XD
