How would Underfell!Gaster, or Fell, react to some teenagers being racist towards him and his sons??

i have 2 ideas of what he would do...the first one is bit obvious of how he is, but i would want to know how would he react if not, if not as his usual... COUGH COUGH aggressive. COUGH self-

(if he would react any diffrently-

Surprisingly, on the rare days he was feeling nice—nice meaning he wasn’t about to beat the fuck out of those kids—he didn’t lash out immediately.

Instead, he let the silence stretch. His gaze dragged slowly over them, from head to toe, deliberate and heavy, like he was cataloguing every flaw and bad decision they’d ever made.

He hummed softly, almost thoughtfully, as if debating whether they were even worth the effort.

Then, finally, with a calm voice that made it sting worse, he said:

“How can you be racist and have acne? Worry about your own skin. B.R.A.T.”

Are there any skeletons (or others) on your list who prefer human partners in bed over other monsters?

Definitely! I swear I answered a similar ask on the main blog ages ago about who prefers to date humans, but I can’t find it so if that’s different than the answer I put here, whoops lol

A lot of the guys would prefer humans over some types of monsters. Many monsters tend to favor others who are built similarly to themselves, and skeletons count as humanoid. 2 arms, 2 legs, stands upright and all that.

Cypress (Horrortale Papyrus) in particular has a fascination with being able to see or feel the outline of a human partner’s bones under their skin. Defined collarbones or the outline of their spine gets him worked up in no time.

Grawlix (Fell Gaster) and Obelus (Horrorfell Gaster) both have what you could probably call a human kink. They’ll still have fun with other monsters, but something about humans just hits different.

Not only are they into how soft humans are, but they also have better magic sense than most monsters and are attracted to how strong human souls are. The thrum of a human’s inner magic getting so heated drives them crazy and they’d definitely try to convince a longterm human partner to get their soul more actively involved in the bedroom.

Who has the worst red flag

Ooo good question, but technically the answer is subjective. Here’s my answer though: (Slight tw for physical abuse, but nothing graphic.)

Personally I think Grawlix (Underfell Gaster) has the worst red flag. He has a history of physically attacking people during arguments or when he gets too mad in general. Grawlix grew up in an awful environment and all he knew how to do was continue the cycle. Red’s gold tooth is proof enough of that.

Now that everyone is free and he’s out of the Underground, he so badly wants to change. There’s potential that he’ll still react violently to a bad enough argument, even with someone he cares about, but it would devastate him. He’d do anything to make it right after.

Regardless of how bad he feels about it, even the possibility of getting so mad he might hit his partner is the reddest of red flags imo

Forgor the addition lol anyways of course part of what brought that thought up was thinking abt that uf au where monsters surface much earlier and Gaster raises Sans and Papyrus on the surface. He'd regularly use Papyrus as a personal heater. Papyrus will just be minding his own business and then Gaster is like Have I told you how much I love you recently son? And then hug him for fifteen minutes to warm up. Papyrus is used to this. In the winter he has to sit in the middle for movie nights so Sans and Gaster can use him as their kotatsu

Underfell monsters are crushing on someone and it seems to be mutual, but then another person pulls the monster aside and tells the monster to not try to flirt with said crush because, "Them and I are already a thing." However, this person is just delusional and decided that the crush being polite meant they were dating. The crush is livid and verbally tears the person a new one when this comes to light and lets it slip during the tirade that the monster's crush is indeed reciprocated.

OH BOY THE DRAMA!! 

----------

Soft Edge

Soft Edge isn’t really much of a flirt, he’s more likely to just be slightly nervous and flustered in your presence. Genuine compliments, that are just soft and endearing are more his thing. So when the person pulls him aside, he’s very surprised. He’s... not flirting??? But he’s kind of crestfallen at hearing that from this person. But then he brings it up with you, saying he didn’t realize you were dating someone already. You stop and ask for details, and he tells you what just happened. You correct him that you’re not dating, and when you say that you in fact, like him, he’s absolutely DELIGHTED. His chest is puffed up, and his head just seems to be held a little higher, as he’s simply full of pride because you like him back. Once this person has been shooed away, he’s asking you on a date. 

Red Boy

Oh he’s so MAD about being pulled aside. Was this really necessary??? What kind of douchebag do you gotta be to do this sort of thing??? “You’re S/O is a douchebag.” He says when he comes back to you. You pause blinking like the blond man meme. Pardon???? He looks confused now. “Ya know, them over there??” he gestures to the person. You tell him you’re not seeing anyone, and you look PISSED. Oh, OH SHIT. You march over, and give that fucker a piece of your mind. Red Boy is hyping you up the whole time, thinking this is absolutely FANTASTIC. But he’s stunned when you say that you like him and he’s just tugging at your sleeve. “Ya,, Ya like me?” He’s asking with hope in his eyelights. OF COURSE YOU DO. HE’S DELIGHTFUL. He’s grinning at ya and kisses your cheek. “Cool, like ya back.” He glances to the person. “Take a hint, Scram.” 

Jerkby

Big time flirting with you, and then he gets interrupted by the person. Um. Hm. For some reason this doesn’t sit right with him. It’s written all over his face, the confusion when he comes back and you ask him about it.

“Are, are you dating someone?” You answer no. HM. SURE SOUNDS. SUSPICIOUS. PERSON. He tells you why he asked, the person pulling him aside. You fucking LOSE IT. How DARE they???? When you say that you like Jerkby when you’re chewing the person out??? He’s pleasantly surprised. Holy shit its reciprocated. hOLY SHIT. He kicks the person out of his bar, and asks you out on a date and makes plans. I mean, you like each other. You might as well right?

Grump

He’s just softer around people he likes, kinder, and when the person pulls him aside. He doesn’t believe it, simply because of the possessive behavior. “Funny, they never mentioned that. I’ll have to ask them.” He tells them before simply striding over to you. He asks you and tells you that they’re saying you’re a “thing” and you’re absolutely PISSED. You chew them out, and accidentally let that info slip of liking Grump. He’s smirking, He’s very happy to hear about this. 

“Well, should we go on a date and leave them behind??” He asks you, interrupting you chewing this person out. He leaves with you, and his aura simply has the SMUGGEST aura.
