I’m going to assume this is specifically a confrontation by an adult human determined to do harm to him or his friends on the surface, as opposed to an adult human falling Underground.

So … once upon a time @popato-chisps mentioned something about a Bad Brother AU for the Underswap universe. And I had this in my head for a while. Basically, in this version Stretch is not exactly … um … encouraging. In fact, he totally does not want Blue joining the Royal Guards and the way he goes about it is by making fun of the very idea.
Blue is resourceful though, he finds ways to find encouragement … somewhere.
It works sometimes.
I really have no plans to take this anywhere. I just wanted to draw this scene out.
Oh wow. This honestly took my breath away. Both the art and the headcanon. This is stunning.
Have you ever thought about diseases not being universal constants? Like a cold-like illness in Underswap becoming an epidemic in Underfell
Okay. I love this idea. It is a fantastic idea that makes a wonderful amount of sense, and I love headcanons that have a basis in logic.
However. I will never be able to write for this idea. It runs straight into the two types of angst that give me the most trouble: character death and severe illness. Anything that a character can’t fight or be rescued from, anything that by its nature can only be logically met with passive acceptance is anathema for me. It feels too much like giving up, and it feels too much like there’s no hope.
So. @crushingonsans, @ollie-oxen-free, @alicedragons, @cheapbourbon? You guys are all much better with this kind of angst than I am. Consider this a plot bunny, if you’re in need of one.
Oh no, don’t tempt me like this. I can definitely see this being an almost apocalyptic sort of fic. And I almost like the idea of one of the Tale universes being susceptible to the disease, and sort of devolving into a world of savagery.
Great. Let me just add this idea to my enormous stack of WIPs. Thank you.
So,how would uf paps react to us paps kissing him?
Hmm UF Paps would be more likely to kiss US Paps with how I see their personalities (and US Paps is probably tsundere) Buuuut-
In the case of US Paps kissing UF Paps, I think Fell would immediately react with a pun, or claim it was his idea.. OR say that Swap lost some challenge that wasn’t even discussed previously xD..
..and then go to ‘cry’ to Tale Papyrus about how awful Swap is and get free hugs from Tale cuz he would be the BEST at hugs

This one came in after I’d posted the rest of them, so I’ll make it the last one. Thank you for sending it in! Kedgeup is really growing on me. (Sorry it took me a while to get to this!)

37. “How much would they be willing to sacrifice for the other? Any lines they refuse to cross?”
I can say, with ease, that these two would kill for each other. Almost unconditionally. They’d probably die for each other as well, but neither of them would ever allow it to escalate to that point. One thing they would never sacrifice for each other however, would be family. Sans wouldn’t do anything for Edge that might have detrimental effects on his own brother, and vice versa. Additionally, I highly doubt either of them would change for the other. At least, not beyond a certain point. I’m sure there are many things both of them would like to change about themselves, but that’s an entirely different conversation.
42. “Do they let each other get away with things that would normally bother them?”
Depending on the circumstances, they might.
Sans is more likely to let Edge get away with things he disapproves of than the other way round, but even he has his limits. He’s generally pretty relaxed, giving the Edgelord free reign when it comes to behaving in a ‘Fell universe’ manner when he’s visiting Sans in his own universe. And normally, Edge understands social cues well enough to know when he’s doing something that bothers Sans (but even this isn’t a very common occurrence). Every now and then however, Edge slips up a little, and might snap. Sans is well equipped to handle a little moodiness – but he will not tolerate any disrespect (intentional or not) towards his brother. If Edge offhandedly snaps at Papyrus, Sans will be on him in a flash. He won’t put up with it. No matter how much shit Edge has been dealing with.
As for Edge… well, he’s been living with Red for a long time. Let’s just say, he’s pretty well equipped to handle Sans’ slovenly habits. He’s actually rather skilled at convincing him to assist with household chores (one way or another. He’s not above using sex to bribe his lazy boyfriend). He’ll also never tolerate any self-deprecation from Sans. He’s very good at picking up signals, and if Sans is going through a particularly ‘bad time’ (heh), he’ll be there for him and more. One thing that Edge lets Sans get away with (which he would never allow in his own universe), is making fun of his brother (or, on occasion, gently threatening him). Sans seldom fails to get a rise out of Red, and while this might bother Edge under more pressing circumstances, he finds it rather amusing when it’s coming from Sans. It’s almost a nice break for him, seeing his brother getting riled up over something that isn’t serious.
This answer is getting a bit long aaah, but I really wanted to add this last bit. As far as their sex life goes, their roles tend to shift a bit from what they might be under ‘normal’ circumstances. While Edge normally prefers to dom (he feels more at ease when he’s in control), with Sans, he likes to be able to let go, and let Sans take the lead. It takes a while, but being with a Tale ‘verse monster gives him a little peace of mind. He feels safer around Sans, and is less reluctant to let Sans take control. Similarly, Sans is normally too lazy to dom. He likes to lie back and let his partner do all the work (whichever set of genitals he forms), but with Edge, he actually enjoys seeing him fall apart, and is happy to put in the work (for a change).
What are some of the similarities/differences in the edge/ufmuffet stuff and the twist/twistverse muffet stuff?
Ooh, a good question. I’ll break it down below the cut. Be warned, though, this will involve discussion of abusive relationships; physical, emotional, and psychological abuse; eating disorders; discussion of cannibalism; rape; coerced sexual relationship between an adult and a minor; and may contain spoilers for both Broken Bones and Sins of the Past.
Right. Everybody ready? Let’s go.
So bby, how about some innocent stretch headcanons?
INNOCENT STRETCH YES! YOU’RE SPEAKING MY LANGUAGE MY LOVE
Underswap Innocent!Papyrus
- People always compliment him whenever he goes out.
- He’s also always invited to people’s houses for some reason, maybe it’s because he has that chill vibe?
- People really like to touch his thigh or lower back and it feels nice, though he’s never really given much thought about it because Blue always ends up pulling him away.
- Undyne…why are you naked with Alphys?
- “You’re one hot skeleton” “Yeah I need some water. Got any?”

You and your gold skulls. (I can’t judge though, I love hurting these two as well).

“How much would they be willing to sacrifice for the other? Any lines they refuse to cross?”
At first – there’s not much they’d sacrifice for each other. While Edge may have a bit of a ‘hero complex’, and would probably risk his safety to keep Stretch safe if he was in serious danger – it would probably take a bit more time for him to do so for the right reasons. But Edge would be quick to develop a protective instinct around Stretch. He would sacrifice his life for Stretch. Literally. If necessary, he would die to keep Stretch alive and safe.
That being said, there are lines Edge would never cross, even for the people he loves. He would never compromise on his morals. If Stretch demanded or requested something of him that Edge found to be unethical, or even just something that didn’t align with his beliefs or standards, he would not do it. And perhaps something else he’d never do for Stretch is change who he is. This would be a definite tremor in their relationship. Stretch might try to encourage Edge to be more open about his feelings – which he might be, to an extent. But he would never change his lifestyle (unless circumstances permitted it) – this includes killing to survive, something that will always bother Stretch.
Stretch is much the same when it comes to sacrificing his life. That being said however… Stretch doesn’t place much value on his own life. It’s rather easy for him to presume to throw it away. In more extreme cases, Stretch might also sacrifice his own mental health for Edge’s sake. He might do things that make him uncomfortable, simply to show Edge how far he’s willing to go for him (it comes out of the innate Papyrus desire to please, Stretch is just a little more subtle about it).
There aren’t many lines Stretch wouldn’t cross for Edge. At first, he might be a little more hesitant to breach boundaries – or even show much true affection – towards Edge. But as time passes, he becomes utterly dedicated to Edge (not in the sense that he won’t leave his side, more that he’ll be there for Edge pretty much upon demand. Stretch likes feeling useful, and helping Edge through rough times is one of his favourite ways to do this).
But, with all this said, Stretch refuses to budge on his more unhealthy habits just for Edge’s sake. Smoking, emotional self-harm, the occasional self-deprecating joke (which Edge hates). Edge tries his best to pry Stretch away from his self-destructive habits, but Stretch is very stubborn, and Edge often gives up trying to budge him (at least temporarily. He’ll never give up entirely on trying to help Stretch improve himself).
42. “Do they let each other get away with things that would normally bother them?”
Yes, but they’re not very good at hiding that it bothers them.
There are a lot of things Edge refuses to allow Stretch to do – things that he deems to be morally ambiguous. Fortunately, Stretch isn’t a particularly malicious person, so there isn’t much Edge has to worry about from him. Perhaps one thing that bothers him (but something he would never get involved in) is the way Stretch treats his brother. It’s not… bad, per se, but Edge doesn’t quite approve. Stretch tends to get a little overprotective of Blue sometimes, and Edge can tell that Blue is less than pleased by this. But he refuses to intrude on familial matters. He may try to mention it to Stretch on occasion, but it often goes right over Stretch’s head, so Edge tends to let it drop.
Stretch of course, utterly detests Edge’s Underfell lifestyle. He hates that Edge has to kill – or even just threaten or intimidate – other monsters. He doesn’t like seeing the so-called ‘Fell’ side of Edge. But there isn’t much he can do about it. He understands that it is a necessary part of Edge’s life, so he seldom interferes. (Often though, when Edge is sporting some fresh new EXP, Stretch might avoid him for a few days. It’s a definite flaw of their relationship, as these are the times Edge needs Stretch most.)
This actually didn’t turn out as angsty as I expected. Don’t worry though, I have plenty of angst coming up for these two hehe.
Thank you for sending this in! This is the last one, hooray! (It only took me about a month).
2, 3, 8, 23, 39 for the relationship and the pair is SF Sans x UT Sans I know it’s a rare shipping but I love these too together and I’m also Sorry for the many numbers, I hope I did not make your time harder with these
Not a problem at all! I like these two, as well!
Also, I’m so sorry I’ve taken so long with these eek! I almost forgot about them, and then I went through one of those ‘no motivation’ slumps. So this is just me trying to get back into the swing of things. Hopefully I’ll have more content for you all soon!

2. “How’s their team work? Do they share well?”
I think that, rather than working ‘as a team’, these two would try and challenge each other. Even on small things. Sans might try to irk Razz by “making things difficult for him” (not to an extreme extent, but more in ways that might set the short-tempered skeleton off, much to Sans’ amusement). And Razz certainly wouldn’t sit by idly and let it happen. He’d do everything in his power to get back at Sans. Sans is a difficult skeleton to figure out, but Razz is very determined, and once he’s able to determine Sans’ peeves, he’d take full advantage of them.
When it comes to sharing, Sans isn’t very fussy. But naturally, this annoys Razz. He sort of thinks that Sans should care that Razz got to choose the movie twice in a row, or that Razz had the last slice of cake, or that Sans offered to sleep on the couch when there was only one bed. Ultimately, they’re both pretty selfless when it comes to trivial things.
3.
“Are they open about their relationship? How do they feel about public displays of affection?”
The short answer? Absolutely not.
To elaborate, neither of them are very accustomed to displaying affection. Razz is especially pent up, and might worry that any kind of feelings for Sans would be a sign of weakness. And Sans is no better. He likes to play himself off as the cool, carefree comedian, but he struggles a little around Razz (partly because Razz throws him off a little, and he often feels like he needs to step in to keep him in check).
As time goes on, they might grow a little more used to each other’s company, and small gestures might become instinctual without them realising it. Still, if either of them catch themselves doing it, they’d immediately stop.
8.
“What do the like best about their partner?”
Razz likes that Sans is a bit of a mystery to him. At first, this aspect of Sans’ personality would definitely teeter him. From a survival perspective, not knowing someone who could potentially be your enemy is a very dangerous thing. But Razz grows to like this. He normally tends to find the Tale ‘verse skeletons boring, but Sans is just the right amount of “creepy” to keep him on his feet – while providing him with some relief from the harsh demeanours of Fell monsters.
As for Sans – at first – nothing. He doesn’t trust Razz. He doesn’t like how unkind and tart he is. He doesn’t like the way Razz walks – that stupid strut and the way he sways his hips as if he’s trying to irritate Sans. Or that stupid smirk of his. Or the way he sounds when he actually laughs (especially when it’s at one of Sans’ jokes, which he certainly doesn’t make just to try and make Razz laugh). Or…
Okay, there are some things Sans likes about Razz. But he’ll never admit them to himself. He might claim that he dates Razz ‘out of spite’. Deep down though, he does see a small part of Razz that he admires. Razz isn’t kind, nor is he generous, or compassionate… or at least, he tries very hard not to be. Sans isn’t normally very competitive, but he almost takes it as a challenge to make Razz – who is normally so cold and stony – laugh. He really likes Razz’s laugh.
23. “How do they hug? Kiss? Tease? Flirt? Comfort?”
As I stated before, displays of affection aren’t really their thing. Their hugs are few and far between, and the ones that they do share are often brief. But… every now and then, Sans can tell that Razz needs a little comfort – and vice versa. In those rare cases, their hugs are long, quiet, and gentle.
Kissing is a bit of a weapon for both of them. Before they start dating, they might try and kiss each other to throw each other off. The novelty of ‘the surprise’ wears off pretty quickly though, and they soon start kissing just because they enjoy it. Razz likes rough kissing, but Sans is the opposite, and he’s pretty good at getting Razz to wind down and take things slowly.
Razz thinks he’s the ultimate tease, but in truth, his flirting isn’t quite up to scratch. He might have a few dirty one-liners ready to throw Sans’ way, but he gets flustered too quickly when Sans throws them right back at him. Sans is a surprisingly smooth flirt, he just seldom brings it out. He’s a master of manipulation, and could have Razz eating out of his palm… if it didn’t take so much effort. Mostly he just compliments Razz’s ass (and it’s enough).
39. “Who initiated the relationship? Who kissed who first? When did they realise they were in love?”
Neither of them really initiated the relationship. It sort of just… happened. If you really had to pick one of them, I’d probably have to say it would be Razz, but perspectives differ.
Razz was extremely persistent. (I sort of wrote a bit of a drabble about this a while ago), but I like to headcanon that Razz asks Sans out as a dare, and Sans goes with it out of spite (and partly because he finds flustered Razz very amusing). And as far as their first kiss goes, neither of them are really sure who initiated it. Once again, it sort of comes out of a dare. Razz is very spiteful, and would never back down from a dare. However, he’d probably get nervous at the last minute and try to back out – but Sans would help him take that final step.
When it comes to love with these two, I don’t think it would be a ‘realisation’. They might quietly admit to to themselves, but it’s unlikely they’d voice it for a very long time. The occasional “I love you” might start slipping into their conversations, but there would never be a “confession” as such.
As I wrote this, I realised that Rottenjoke is sort of the Spicyhoney of Sanscest. Good Ship™. Thank you!
(I just have one more to go now, I’m sorry I’ve taken so long with these!)

Lol. I think maybe I have a reputation. Answered in numerical order below:
Your headcanons for them are exquisitely angsty! Just the way I like it. Although your ‘break up headcanons’ are probably a bit more realistic than mine, I’m one of those people who likes to loudly proclaim that their love is eternal and shall never die. (But given the nature of their relationship, this isn’t always entirely plausible, sadly.)
