Butch: first, to get this rough skelly to bottom, you have to be his soulmate. No one else would ever get the trust needed from butch for it to happen. After that though, just ask! Butch will be hesitant and probably won’t take it seriously the first time his SO tops him, but he’ll find he really likes it and is down to give up the reigns- for special occasions only of course.

Wine: you’ll use a favor to get wine to agree lol. And of course only a SO will get the pleasure. Occasionally wine will use his SO for an unsavory task like giving him an excuse to ditch an annoying customer or taking the fall for his own slip up. In exchange he promises a favor of SOs choice equal in value to what they did for him earlier. He’ll be quite amused by this request and is surprisingly good at playing the part of the submissive and eager partner in bed.

Basilisk: while basilisk is truly a dom at heart, he also prides himself on being the best at fulfilling his mates wishes. So if they want to top, he’ll do his best to let them. He will insist on restraints though cause he doesn’t trust himself not to get too excited and switch roles during lol.

Papyrus: he’s down to sub when it comes to trying new stuff with his partner! But then they have to agree to letting papyrus try the thing but with roles reversed next time! He always winds up enjoying when he’s in charge more, but he can’t truly say he’s adventurous if he doesn’t look at both sides of the kink!

Bonus:

Sea Glass: Upon consulting with Vi (the one who asked) I will be replacing this Gaster with How To: Gaster, as Sea Glass Gaster doesn't really exist. And not in the "yeeted from the universe" way, and more in the "I literally have no backstory for him" way.

How To: Underfell Gaster. He's a hardass, but when you get past his prickly exterior, he's actually a good person. He disguises all his acts of kindness with insults, and hired Sans so he could keep a better eye on him and Papyrus. He never got the chance to adopt his Sans and Papyrus before he fell into his creation, but he sees them as his sons.

You can see more information bout him in this ask. We'll call him "Boss."

Pirate!AU: The former royal scientist and retired pirate captain who now lives with his hot tavernkeeper boyfriend and their raccoon. He adopted his sons, Sans and Papyrus when they were kids, and they are now the ones that are in charge of the Sail la Vie (his former ship). There was never a barrier in this world.

You can read more about him here: [1] and [2] (this is a oneshot about him and Grillby.) We'll call him "Pyre."

Heart on the Table (HotT): An absolute softy, and canon-compliant Undertale Gaster. He adopted his sons, and while he was clumsy with parenting at first, he loves them with his entire soul. He fell into his creation when Papyrus was still a kid and Sans a young adult.

However, his story didn't end there. A large portion of his soul actually got trapped outside of the barrier where he roamed, unable to be seen or heard or touched. ...Until he met Frisk! Whom he immediately adopted. As of right now in the series, he's trapped outside the barrier while Frisk is Underground. (well... at least most of him is trapped out there.) For the purpose of this ask, it will take post-reunion (with minimal series spoilers regarding how that will happen)

You can read more about him in the Finding Home series. We'll call him "Wings."

Lamiatale (Aka "Mr. Snake Smoocher (bald edition)): And this is where the problems start. This description is going to be longer to the others because there is no content posted for it yet on my tumblr or ao3.

All the other Gasters so far are good people. This Gaster... is not. He's a human scientist with a craving for knowledge and recognition.

He runs and operates Ebott Zoo - the only zoo in the world to boast a magic exhibit. Sure the lamia and the sirens eat people on occasion... but what the media doesn't know doesn't hurt anyone!

He's fully aware that the lamia and sirens are as intelligent as humans - but until they're willing to talk with him and negotiate, they'll be staying right there in the zoo. Too bad Sans, the oldest of the lamia at the zoo, has no intention of cooperating with the man who betrayed him. And where Sans leads, Red and Fell follow.

But despite everything... Gaster is still in love with Sans, and is consistently found begging with the prideful skeleton to just give him a chance. That if he just helped, things would go back to how they used to be when they were young and in love.

We'll call this Gaster "Doctor."

Now lets get to it!

To start with - all four of the Gasters will be investigating the situation first, before they even really think to talk about themselves or make idle chit-chat. They'll be fascinated by the fact that one of them is human, and vice versa, but after taking note of that, and establishing that they are all, in fact, Doctor W.D. Gaster, they'll be back to theorizing about why they're all together all of a sudden.

Pyre and Doctor will be the most confused, as neither of them were... well. Voided. Boss and Wings will be trying to figure out why the void has suddenly crossed dimensions.

Theories will fly around the room, incomprehensible calculations and math... they're all quite happy to find an equal level of intelligence.

It's only when they've finally figured out that there's... well. not much to figure out, that they'll sit down and actually start chatting with each other.

Wings and Boss will probably pair up to talk at first, since they both come from startlingly similar universes and situations. They quickly realize that they had near identical upbringings, and quickly deduce that their timelines diverged after they ended up underground.

Wings is fascinated and horrified by the picture Boss paints of his home - one where cruelty goes rewarded and kindness punished. He's also... uncomfortable with the lack of mention of any sons, but not suprised. In such a cruel world… would he have given a second thought to Sans and Papyrus? Would he have even known they existed? He doesn’t like thinking about it.

For his part, Boss shares most surface level things, but like any fell monster, he keeps what he really treasures close to his chest. He doesn't mention his Sans or Papyrus, and he doesn't consider that Wings may also have met them. Things are different - the world kinder - surely in Wings's world, Sans and Papyrus were never orphaned in the first place?

That's until Wings's starts talking about his world. It becomes clear to both of them that Wings's is a shut-in, who only really knows much about his own corner of the world. ...And about his children.

When given a chance, Wings will do what Wings does best - and that's talk. You can't ever get this skeleton to shut up about anything, and one of his favorite topics is his children. He's going to sing all sorts of praises about his kids - how funny and clever Sans is, how proud he is of him for taking a step back and relaxing. How intelligent and driven Papyrus is, with a strong sense of integrity to boot. How determined and kind his little Frisk is, so small but getting bigger every day now that everyone is healthy.

Boss is going to get very very uncomfortable, though he won't show it. Mainly because jealousy is now simmering through him so hotly that he burns with it. Because that's the life he always wanted. Sure, maybe Wings still suffered, but he got his sons. He eventually got out of the void. Boss doesn't even like humans, but for the sheer principle of it, he's jealous of Wings for Frisk, too.

In Boss's world, Frisk is Papyrus's child. Perhaps... maybe... if things had gone differently, they would be his grandchild. But they aren't, and those boys aren't his. They're his employees, and maybe he took on a more parental role than a boss normally would, but he'd wasted his time. He hadn't adopted them when he still had a chance, and now he never would again.

When Wings presses and Boss finally (reluctantly) admits that he thinks of the boys like his sons, Wings... pities him, though he tries not to show it.

Wings never wants to think of his life without his children.

Aaand on the other half of the room!

I imagine Doctor and Pyre will pair up to start talking at first, as their universes are more similar. There's no barrier in either of them, and both men live on the coast. Doctor will be utterly enthralled with the fact that every other version of him here is a skeleton. Pyre has no love for humans, but neither does he have a large bias against them, and so he will eagerly sit with Doctor as they discuss the differences between their worlds.

Doctor is completely enchanted with the skeleton across from him, and he wonders if that's why he's so drawn to monsters - because apparently, in every other universe, he is one. Meanwhile, Pyre is sitting back and spinning tales as he is wont to do - he's quite the entertainer.

That is, of course, when Sans's name comes up.

Immediately Doctor perks up and presses Pyre for more information on the skeleton. Some of the questions are... overly familiar. Pyre is using Sans's name to talk about him - he hasn't said "my son", and so neither of them quite realize exactly what's going on.

Until, inevitably, Doctor asks something that's too familiar, and inappropriate, and Pyre sputters.

"Why the hell would I ever want t' know about me son's sex life? I taught 'im how t' be safe 'n dat's all I care t' know! I don't want t' details!"

"Your SON?!"

Immediately the room goes silent, and Wings and Boss are moving over because there is SOMETHING going on here, and they aren't sure they like it.

Pyre is sputtering.

"Yes, me son! What else would he be? Ye! Tell me Sans and Papyrus are ye sons, too?"

Pyre drags Wings and Boss into it, and Wings immediately confirms, though he also adds on that he has another child, too - Frisk. Boss hems, haws, and mentions that Frisk is Papyrus's child in his world (of which Pyre agrees that Frisk is Papyrus's in his own as well - they're his grandchild). But eventually Boss is too curious about what's going on to really deny it, and admits that they were his children in everything but legality.

They're all facing Doctor now, who is staring at them in utter fascination.

"Children? I imagine you are older than them in that case, by a fair bit."

They chime in with their ages - Boss and Wings are nearly the same, though Boss is a handful of years younger. Both are in their 900's though. When Pyre admits that he's 148, (though that's firmly upper- middle aged for him - his life expectancy is around 200) both Boss and Wings tease him for being a baby.

Of course, they then find out that Doctor is in his early 40s and while they partially expected it - he's human after all - it's still an odd shock.

Doctor then hums and says that Sans is the same age as him, and (very carefully, without admitting the details of what happened to break them up - Doctor's not an idiot, and admitting to kidnapping and putting monsters (and an alternate version of their son! how fascinating!) in a zoo when he's clearly outnumbered is a terrible idea for his health.) He casually admits that Sans was his lover.

Needless to say, Pyre, Wings, and Boss are all very uncomfortable with this information, though logically they figure that there's nothing... truly wrong with the relationship. They aren't related, and there isn't even an age gap.

Still. They're all feeling very squicked out. They'd really rather remove this knowledge from their skulls, actually.

From there... well. That's about it. None of them really hate each other, though they're all vaguely uncomfortable around Doctor. They just put that on the whole "he was his Sans’s lover" thing. Pyre, Boss, and Wings, get along pretty well, both Boss and Wings taken by Pyre's stories of the high seas. ...And his stories about the raccoon he lives with (both Wings and Boss discard these as rubbish, and Pyre bemoans his fate of never being believed.)

Doctor's crimes may very well never come to light. He’s actually quite clever and tricky! He’s not going to freaking admit to what he did. Let’s say… the topic of how they got their scars came up. Doctor would simply say he doesn’t like thinking about it and is uncomfortable with it. He’s incredibly closed lipped, and while the other’s may find themselves increasingly uncomfortable around him, Doctor will not admit to anything incriminating.

But Doctor deserves some good old fashioned justice, so lets just turn this into a full on chaotic, random crossover and dump both Lamiatale Sans (and lamiatale Frisk in order to give him some incentive/motivation) in the void with ‘em.

Boss, Pyre, and Wings are all immediately VERY curious of the fact that he’s—well, half snake, and Sans and Frisk are about to be bombarded with well meaning questions. Sans and Frisk, on the other hand, are going to be very slowly backing up. …Actually this would be a mess for more than one reason. Maybe I shouldn’t have chosen this to be the way Doctor’s crimes are revealed… Cuz like. Sans would immediately grab Frisk and hide them behind himself and puff up in a threat display, and Frisk’s fear is going to be so palpable, the Gaster’s would be idiots not to see it. They’re probably about a second away from fainting. …Fear of Sans, that is, NOT anything else. (Frisk and Sans have a complicated relationship :) )

Ummm I could turn this into a whole mini fanfic, but to show restraint for your sake and not derail too much from the gasters, I shall refrain. Let’s just say, one thing turns into another, with Frisk’s presence, Sans isn’t able to hide his voice, and it all eventually comes pouring out.

Er. for purposes of this ask remaining gaster centric, I’ll also say the void is preventing Doctor and Sans from physically interacting. Meaning Sans can’t just. Kill him and be done with it. Sans will (eventually) realize that the other Gasters are VERY much on his side (which… they’re monsters too. yes. that makes sense. He still doubts their INTENTIONS, but at the very least they wouldn’t be harming him in the same way.) and when he realizes someone might actually be willing to deal justice on his behalf… well. He will tell Frisk to cover their ears and then begin to describe, in depth, what Doctor had put him and the others through.

Now then. Let’s get into the gasters again. Furious doesn’t even begin to cut it. And Doctor is, by FAR, the least powerful one there. He’s just… a human. He doesn’t even really have the advantage of INTENT, because Boss and Wings have literally already been dead and scattered and can’t be killed like that. In Pyre’s case, he’s quite practiced at killing much more trained humans than Doctor.

Pyre and Boss have both killed humans for way less, and with Sans THERE, they aren’t feeling particularly merciful. This may not be their son, but he LOOKS like him, and acts like him… it’s enough for both of them to be very VERY protective.

Wings will be concerned with making sure Frisk can’t hear or see what’s about to happen… but once he’s reassured their eyes and ears are covered, he’ll be turning right back to copious amounts of violence.

He probably won’t actually take place in what’s about to happen though.

Don’t get me wrong—Not a single one of these Gasters are pacifist people. Not even the softest of them. Wings would gladly tear a man’s head off for hurting one of his kids. But, eh, torture doesn’t settle right in his stomach. To take part in. He won’t stop it though, and he’ll gladly get a couple kicks in before retreating to distract Frisk. (Sans does NOT like the man’s proximity to Frisk, but he’s doing a better job at distracting the kid than Sans is, so… not much he can do.)

Boss and Pyre on the other hand…? Yeah. Uh. They have nothing against actual, drawn out torture. Doctor is going to WISH he were dead by the time the void releases them all.

Doctor doesn’t even blame them. He, too, is possessive over what he sees as his, and he just sees this as the monsters staking their claim. He sees much of himself in them.

They do not like hearing that. And Doctor is the one to suffer for it.

(All of them are going to be reexamining themselves after this and fearing that they are horrific abusers. Boss is going to be the one who spirals the most as he draws comparisons. It’s not going to be pretty mentally.)

Aaaaand I think that’s about it?

TLDR: Wings, Boss, and Pyre would get along swimmingly, though Boss and Wings would have an odd, jealousy based relationship.

All of them would be uncomfortable around Doctor, and if they found out what Doctor did, they would have his guts and also beat him up. A lot. It would probably end with his death, unless the void interfered in this.
