#sans deltarune becomes sans undertale. papyrus deltarune changes his identity entirely and becomes gaster undertale.

while i think it’s unlikely to be canon, one of the reasons why i kind of like Gaster Middle Bro as a headcanon is that i think he could be interpreted in a lot of ways as being a middle ground between Sans and Papyrus and it’s kind of a cool play on his broader duality/dualism. it’s like those two are the voices of his internal dialectics. thinking back to old school UT theories of "sans and papyrus are clones of gaster and/or two halves of him after he shattered" + the idea of "gaster’s body is in UT’s universe but his mind is in DR’s," sans is kind of the head (detachment, caution, self-preservation) and papyrus is kind of the heart (investment, conviction, compassion). the decisions he’s making now seem to be a strange middle road as well (he seems very invested in certain ideals/outcomes, but he doesn’t want to be known as the responsible party if the consequences are bad; he won’t take action himself, but he will quietly exert influence in the hopes that someone else will do it). this argument could work for Dadster and aforementioned "halves"-type HCs as well but i think i especially like the idea that gaster was the one picking up and internalizing these influences from his brothers rather than those two just inheriting their respective halves of his personality

Actually yes .Said friend found this mentioned in a fanfiction and was curious, so he looked up the information. And also, I'm not talking about your au, I'm talking about canonically. The holes in gasters hands are because of Sans and Papyrus. They were literally made from him. Plus they're skeletons ? They don't have "parts"

I’m adding your other ask because some of the things I’m going to mention are going to discuss things that pertain to both.Which Fanfic? Because MsMk fanfic is an entirely different timeline. If its a fic from ShadowFoxDemon, that is also a variation of a timeline. Possible outcomes. I’ve already discussed that this is all a matter of “If Seriff was in the Multiverse.” Both of which that in, Yes indeed, I cover and answer questions for.

Amazing, isnt it? How one can think of different outcomes for possible changes in a persons life that can effect who they become? Almost like there are multiple versions of Sans and Papyrus that people have made because of possible “What If’s” that came to peoples mind that other people build off of to make other variations of that variation! OHWAIT!I’M ONE OF THOSE PEOPLE! 

MSMK IS ONE OF THOSE PEOPLE!

A GOOD MAJORITY OF THE UNDERTALE FANDOM ARE THOSE PEOPLE.

AMAZING! 

Also, it is not Canon that Gaster made Sans and Papyrus. It’s not confirmed, nor is it in Undertale or DeltaRune. Its a theory, an idea that most of the fanon like to headcannon. However Toby has not confirmed this so until then that’s just a theory. (A GAME THEORY)

Also did you?? even read?? the first part??? of the answer I sent you??? If so, I’ll say again. Human Skeleton’s do indeed have different parts that show that if they belonged to a male or female. A simple google search can tell you that. I’ll give you a hint, its called the Pelvis bone. I mentioned that before in my last answer too.“If your au is really like any other au, then he can change his body to whatever he wants ,no drama or anything needed.” Um, if it was his ecto-body, flesh made of magic that monsters such as himself can create, then yes he could. However if you’ve ever taken a science class then you’d know that bones aren’t built to be changed.

Also, I haven’t changed the original storyline for Sielutale? I changed some elements, updated it and polished it up a bit, gave additional information. Still currently doing that to be honest. Unless of course you’re referring to all the fanfics, that I’ve already said is part of a timelines. Or unless your referring to the Original Storyline of Undertale, to in that case I hope to fucking god I changed the storyline. Thats the whole point in making an AU after all. That’s why they’re called AU’s, because they’re Alternate Universes.

Also, what does Seriff being Trans have to do with me updating the original storyline of Sielutale? I’ll tell you the answer: Fuck all Nothing. He was trans when I first made this AU. The changes to Sielutale have been towards character development, story, and the physiology and culture of Sielutale Monsters.  But not the genders or gender identity of the monsters mentioned.

Just because I’m willing to talk with askers and others about different versions of Seriff and his future, doesn’t mean that its canon for the main Story of Sielutale.
