Classic, Swap and Fell bros with an S/O who owns a lot of dogs and cats? Like, a LOT. Upwards of ten.
Undertale
Sans gets along well with both cats and dogs, as long as they have a good temperament. He likes to play with dogs and cats by using his powers to move their toys around.
Papyrus, as we all know, isn’t the biggest fan of dogs, but…he’ll put up with them for you. It’s really the young or more energetic dogs that he has a problem with, because they tend to get into mischief with him, so the calmer the dog, the more he’ll like it. He’s a cat person by default.
Underswap
Sans hasn’t come across many cats in his time, so at first he’s not sure how to behave around them. Once you show him, he gets the hang of it. Despite his run-ins with Annoying Dog, he actually loves him, and all dogs in general. If only he could train him to do something useful so he wouldn’t keep carrying away his awesome attack. He might try to bring one of your well-behaved dogs out on patrol with him.
Papyrus can tolerate dogs, but he’s more into cats. He’ll still lazily pat any dog that approaches him, but there are days when you come home and find him softly snoring on the couch with a cat or two nestled in his hood.
Underfell
Sans is allergic to cats, so that’s something the two of you will have to discuss. He’s an automatic dog person and will actively play with them when no one’s around.
Papyrus has some…issues…with dogs, especially with the noise volume. He consciously avoids the dogs and spends more time with your cats, when he can help it.
How would the ut main six react to a child with no soul falling into the underground?
Toriel doesn’t realize it until she tries to fight you to stay and nothing is summoned. At first she thinks you’re somehow holding it back because you refuse to fight her, but after the situation is explained she’ll settle for talking you out of leaving instead.
It makes Sans uncomfortable because he doesn’t have the slightest clue how you’re going to act. It also renders you invincible to attacks since monsters can only fight your SOUL so he practically stalks you the rest of your journey.
Papyrus doesn’t think much of it other than the fact that he can’t impress you with his blue attack. Other than that, he pretty much treats you the same way he would Frisk.
Undyne immediately doesn’t trust you. Well, even more so than she initially distrusts Frisk. Humans are supposed to have SOULs, so something here really isn’t right. Unfortunately she can’t fight you; all she can do is detain you until she can hand you over to Asgore. Hopefully he can figure something out.
Alphys is wary but also REALLY curious. How are you alive if no SOUL? Was there an accident at birth? Does this mean you can’t process emotion like most other humans do? If you appear civil, she’ll have a lot of questions ready.
Asgore is surprised at first. Not only does this mean he can’t fight you; it also means that he can’t use you to break the barrier, so you came all this way for nothing. He offers to let you either walk out like the confrontation never happened or let him adopt you as his child.
How would UT! and US! Skelebros react to a Mage S/O who absolutely loves magic history and would passionately talk about it, but barely does? (Think of family teasing/insulting)
Dude this is like one of my Mage OCs.
Undertale
Sans is genuinely curious to hear what you have to say on the subject. Sometimes, when you finish reading a chapter of a magic history book, he’ll ask you to summarize some of the stuff that you found interesting, or if you seem down, he'll want your opinion on a magic history topic that he read about last minute.
Papyrus loves the way your eyes light up when you talk about the subject and encourages you to talk about it more. He also goes to the Librarby to learn more about the magic history of monsters.
Underswap
Sans isn’t the best at storing all that information in his head, so he might ask repeat questions every once in a while, but he really does find it fascinating how knowledgeable you are on such a vast topic. He encourages you to write a book about it.
Papyrus doesn’t always follow everything you say when it comes to theories and methodologies, but he tries his best to absorb as much of it as he can. He’s really interested in historical figures, like Morgan Le Fay and Merlin (he read La Morte d'Arthur when he was younger). He thinks they were actually real people until you tell him otherwise.
How about a polygamy ask if you're interested? :) What if the US, UT and UF Skelebro's crush already has a partner but both of them fall in love with the skeleton and want them to join their relationship? How would the skelebros react to that? Who would be hesitant or not want to at all? Who would be 100% up for it?
In the end Blue really wants to be with you, but he wants you to be happy. He spends a great deal of time thinking about it and decides to give it a try. He ends up becoming great friends with the other partner, but he only has a romantic attachment to you.
Saffron is a bit too possessive for a poly relationship, so he politely declines.
Classic just rolls with it. He probably wouldn’t start a poly relationship himself, but he’s totally cool with joining one. His approachable and easygoing personality makes him a good partner to all.
Papyrus prefers to put invest all of his romantic energy into one person, and honestly more than one partner would be a little overwhelming for him.
Red wants you to himself. He won’t even entertain the thought of sharing.
Boss doesn’t easily trust those he doesn’t know as well. If he knows your partner as well as he knows you and deems them a good person, he might consider it. But if not then the answer is likely a no.
What jobs do the UT, UF, US and SF Skelebro's get when they're on the surface?
