Can you tell us about your horrorswap boys?? I'm always curious about how people would change horror to be swap

I. Completely missed the boys and wrote out an entire brief synopsis of horrorswap in general. Apologies. It took a good minute more to write out a new response aha.

Anyways! The boys! Rust and Coal! So, as per standard HT origins, things in their underground were as normal as any other US before the 7th child came and went and unintentionally left them in the lurch. Papyrus is still the one who winds up with more significant mutations, while Sans has...fewer.

Due to the events of everything that transpired underground, the brothers' relationship winds up very strained. Once Rust realized the extent of his brother's deceit, he was deeply upset. But by that point, things had worsened so much that, after the initial reaction, he found it...funny, in a way. He developed a distorted sense of reality from both the trauma, head injury, and, yk, everything going on, that left him a bit unpredictable and sometimes even violent. But with time, he levels out a bit into being incredibly cynical and bitter.

In the event of surfacing, he'd be...quiet. Avoidant of others. Not exactly hateful, but very distrusting. He'd be tired, and mostly just want to keep to himself. He'd have a hard time coming around to...surviving, basically. And it'd be difficult to trust the reality of the situation for a while. He'd struggle a lot with nightmares and probably have to take significant medication to help with insomnia and psychosis, but with time, I think he could come around to finding peace.

Despite everything he does forgive his brother, and looks out for him after he loses most of his vision.

As for Coal. He did what he had to to keep his brother alive and he'll never regret that, but after the betrayal of Alphys and being pushed to make terrible decisions, Coal's drive to survive strains his soul more than any mutations.

He experiences delusions sometimes, and his moral compass is more or less entirely dismantled to prioritize he and his brother's survival. If he wound up on the surface though, he'd...slowly begin to reestablish a more firm sense of reality and consequence.

He's spent so long forcing himself to behave a certain way for his brother's sake, and for other monsters who depend on thems' sakes, that it's very, very difficult for him to less himself experience and express emotions in a healthier, more varied way than manic cheer or frustration, but with medication and a very significant amount of therapy, he would likely become more like his old self.

Being fully honest with himself and others would be the biggest hurdle, but at the very least, he would eventually be able to have an actual conversation with his brother again, which would be a lot.

They're both super messed up! But they deserve a break, and if they ever did get to the surface, I'd think they'd get one.

Rust would likely become something of a handyman, though in whatever way warrants as little direct interaction as possible, and Coal might get into botany, honestly! They'd both likely prefer very tangible things that remind them of where they are and that they're in control of themselves.

Rust usually keeps his mouth entirely covered, and his right eye socket is always full of diffuse magic, while Coal is mostly blind and sometimes leaks excess magic from his teeth or eye sockets.

Bonus slightly outdated ref! <3

Horrorswap and Horrorfell Skeleton Boys (Info Dump: Revamp)

Warning: Blood, death, famine, etc.

Chai - Horrorswap Sans

Personality: He's a sweet skeleton man, but he has problems. He is a self-assured and compassionate man who enjoys sugar. He's a touch apprehensive and keeps his lovely confidence to himself unless he's with someone he trusts. He is a massive cuddler who will defend everyone he loves. He might be a touch rough while defending someone. He is also concerned about your health and ensures you eat properly and drink lots of fluids. He enjoys assisting others whenever possible. He has also learned self-care. He tries not to stress himself out, so he learns how relax when working on the farm.

Appearance: Chai has a scar on his left eye that is jagged and looks very painful. He has a small scar on the edge of his left eye. He also has sharper canines than average. He wears mostly blue!

Ceylon - Horrorswap Papyrus

Personality: He is a lovely, hilarious skeleton trickster with trauma. He tells jokes, but his sense of humor is off, and he is aware of it. He's always tense and angry at first, but as you get to know him, he's actually rather kind and friendly. When you first meet him, he's a little antagonistic, but as you get to know him, he's extremely lovely. He has a significant scar on his eye and dislikes it when others point it out to him. If he believes you are underweight, he will feed you. If you hug him when he's happy, he'll never let you go. He is an excellent farmer and worker.

Appearance: Ceylon looks like Stretch and he has a scar from the top of his skull through his left eye socket and down his cheekbone. Ceylon also has a white eye light on the right and an orange one on the left. He also had sharper-than-average canines. He has two small scars on the edge of his left eye.

Chive - Horrorfell Sans

Personality: He's a feral cat bone guy who's been through a lot. He is exceedingly guarded and aggressive to individuals he does not trust or like. If someone is genuinely pleasant to him, he will soften and relax enough to joke with his new acquaintance. He doesn't hesitate to protect his loved ones and is very loyal to them. When someone threatens his companions, he becomes furious and must be kept from tearing the individual who harmed his family limb from limb. He is very affectionate but difficult to get to purr, but with the appropriate training, he will.

Appearance: Chive has a large crack in his skull that runs across his skull leaving a nasty crack from the top of his skull to his right cheek. It is incredibly jagged. He has two red-eye flights. He is a skeleton with a scar on his left eye and two golden teeth. His jacket is red and black.

Cassia - Horrorfell Papyrus

Personality: He's a feral cat bone man who's seen a lot. Anyone who believes they have the right to insult his or his brother is confronted with hatred and contempt. He will be compassionate and kind to those he trusts, as well as protective, frequently shielding his loved ones with his arms. He is a very affectionate and loving individual. If his brother or loved ones are threatened or harmed, he is not scared to break the threat apart. He doesn't back down and is willing to do anything to keep his loved ones safe. He's the hardest of the brothers to calm down.

Appearance: Cassia has sharper canines compared to his already sharp teeth. He also has four scars on his right eye and each is jagged. He also has a cane or an optional wheelchair.
