THERE WAS A THIRD SKELETON BROTHER?!! Undertale/Deltarune Theory 

True

KBXNSBXKSNCLSD

Do it already

You should, it's rather short

Or the events were so traumatic papyrus mostly blocked them out. If the theory that sans and paps are from deltarune originally are true (sans lab and the Q&A heavily imply this to be so) then something terrible like the roaring causing them to have to move to an entirely new timeline/dimension and apparently never being able to return home would certainly cause that.

Counterpoint, papyrus is a mini-boss monster (I don’t remember the canonical term) and Sans is a boss monster. Boss monsters don’t age without having kids. So it is still possible knowing how long the brothers could’ve been alive

@@nell990Only Asgore, Toriel, and Asriel are boss monsters

​​​@@nell990 Boss monsters are a speices of monsters and we see that speices in game those monsters being Toriel, Asgore and Asriel (you may have thought of them as just goats) while Sans and Papyrus’s speices is skeleton monsters (not actual human bones)

@@CowboyCheeseslime Those are only the boss monsters you get in every play through (except for asriel, being the one who proves otherwise because you get different forms of him in different play throughs)

@@nell990 are you saying papyrus and sans are potentially goat people???????

I personally think Grandpa Semi is his own character as there is an unused theme for him (for odvious reasons) that sounds like metal crusher then using gaster motif. He's more than likely Sans and Paps Grandpa that I could see you meeting him in snowdin forest and have him be a sort of guide???? for blue attacks (and maybe other colored attacks if Toby planned on other color attacks)

I think Grandpa semi was likely scrapped early on, and then reworked into Gaster.

​@@simoneperkins4419not unused, it's used in the temmie fight

@@waluigiisthebest2802 gaster has a lot of importance to deltarune and deltarune was conceptualized first personally i believe they're two separate characters with gaster being added to kind of tease deltarune

@@kotostrieb While deltarune was conceptualized first, we don’t know how much has changed or added since Toby first came up with the idea. For example, Ralsei’s possible connection with Asriel wouldn’t be important if Asriel wasnt even conceptualized yet. Also, sans and papyrus were conceptualized during Undertale’s planning stage, and considering the font theme, it wouldn’t make much sense for Gaster to be conceptualized first. The joke of sans and papyrus is that they are named after fonts that are hated, while WD Gaster is named after a font that is mysterious and unreadable. I think that it’s possible Gaster is a combination of a character from Deltarune’s early concepts, and Grampa semi. Gaster is a sort of meta commentary on a scrapped character, and Grampa semi is the only known scrapped character with any sort of plot importance, as the rest are just random npcs and battle encounters.

He would definitely do something like that 💀

Even if it is Gaster, Papyrus still totally has a pet rock called Century Gothic

​@@captainkawaii666This is now canon cause I said so

I agree it's more likely the entries were all written by Alphys. I just wanted to acknowledge the POSSIBILITY some were written by Sans since it's such a popular theory.

@@TheSoph_ Ah, I see. Your phrasing in the video though was as using it as *evidence* for a further theory, as "sans' distinct writing style in the true lab entries".

​@@TheSoph_you phrased it like a fact though which you should never do

If it was a scrapped character why censor it on a paper of a scrapped character idea? It doesn’t make any sense and it’s far more likely that Toby fused the concept of semi with gaster.

@@CrackedcrippleToby is definitely the kind of person who would censor a completely different character to make us think that it is Gaster just to troll us.

I was thinking the same

It's also possible that Toby merged the concept of his mysterious doctor character with the idea of a mysterious third skeleton brother at some later point.

@@trondordoesstuffyeah this seems likely

This also makes me think of Sans dialogue in Deltarune. He keeps saying something about how we should meet his brother soon. The obvious interpretation here is that he's talking about meeting Papyrus, who seems to have trouble making friends. But considering how Toby seems to like using vague, misleading dialogue and that Sans never directly mentions Papyrus when talking about his brother, it's fun to think about Sans talking about another, mysterious brother.

@@Patrick11nf yeah, totally. i feel like there’s a trend with gaster in which toby will suggest information about him while obfuscating it/making it harder to confirm by also associating those traits with another character - ex. “strange symbols” on a blueprint that are equally likely to refer to gaster’s wingdings or alphys’s bad handwriting, piano being relevant to both gaster and kris, and of course sans’s mysterious little brother being most likely papyrus but also encouraging “what ifs.” whether or not the specific brother in question is actually revealed to be gaster, i definitely think there’s intentionality in toby fox seeding the idea that it *could* be him. even if it’s too early for him to confirm anything outright, it seems like he at least wants us to be thinking about that as a possibility.

it's a time machine or worldline traveling device

oh and also it’s totally gaster I would be so floored if it was revealed to be someone else later on

How do you know that? Gaster was around the 201X, and alphys was there when queen left. So alphys lived during gaster era. And i dont think alphys looks too old. Not even really older then sans.

@user-09853 it was argument-->conclusion structure. I literally had the argumentation for that conclusion right above.

Sans and Papyrus are absolutely main characters due to numerous recurring appearances and strong plot relevance. In particular, Papyrus crucially takes initiative in forging an alliance with the human and ingratiates them with the head of the royal guard. Sans is also important since he's specifically designed to be mysterious and make you curious about him, feeding into the reverse psychology the game uses to encourage players to play the genocide route. With that in mind, Sans is arguably *the* final boss of the game. By the way, the blueprints aren't for gaster blasters. Papyrus actually implies that he's capable of using the gaster blaster when he refers to his special attack, "Had I only used my special attack, you surely would have been blasted to..." and he keeps it in his room with the rest of his bone attacks. Your idea does sound pretty cool though.

@@asdffdas254 I agree with u, Sans and Paps are defin. main characters (and important in their own ways); OP's take that they aren't was kind of weird to me. Also, while I don't believe the blueprints in the workshop were for GB's (Sans has fought Flowey in the past, and most likely used his GB's against him. And because it would have been really hard to build like 100 or so GB for the final fight in Geno route. Like Sans is smart and stuff, but that doesn't seem like a lot of time. And also, while they could be created in some way, and/or etc., I do think Sans was summoning them and they are apart of Sans' magic. And probably at least Gaster and maybe Paps too), Paps is only IMPLIED to have GB's. It could be literally anything. And to be frank. I don't really know how one bone would be able to contain GB's. Saying that, he could have GB's, but it is only really only slightly implied.

I mean, Sans does (imo) have a scientific background considering his secret lab, talks in Geno, and just how very smart he is. And etc. He also has GB's, and talks about people he will never see again. Gaster also talks in Wingdings and/or is named after a font, and looks like (imo) a deformed, goopy skeleton. So I do think he might be family to Sans and Paps. Or at least apart of the skeletal race. There are also certain things u can only see in the secret lab or something like that, if you see/use/get some Gaster related thing (I forgot what at the moment). Sans and Alphys are a couple of the only characters besides like Gaster and the Gaster followers, to have fun events too. Which further shows connections and/or possible connections. And etc. Tldr: I do think Gaster is related to the skelebros in some way (though, how he is related to Paps is a bit less clear to me. But still), though it could be as family, co-workers, friends, etc. We don't really know. (P.S.: I am pretty sure Toby was originally gonna have Gaster be a step-father, but didn't. So I do think brother is a bit less likely compared to some other stuff. For that, and some other reason(s) I kind of mention in this comment. "Sans and Papyrus are not main characters, and they are intentionally kept on the sidelines for most of both games (or in Papyrus’s case, excluded completely)." Yes, they are. They both have some of the most screen-time in UT. Paps gets all these phone calls too in the game (which sometimes include and/or talk about other characters), and Sans has the neutral calls and stuff too. They both have importance roles in the game(s), and are main characters, so they aren't is pretty, strange imo. They certainly aren't sidelined either. Though Sans does like to watch/observe/guide/manipulate/etc. you, but still, not "sidelined". "And we can’t assume that Sans or Papyrus remember anything about a person who has been removed from space and time. For all they probably know, the only family they have is each other." Sans does have a picture that says "don't forget" picture, other pictures of people (of people that Frisk doesn't recognize though), and a picture of Sans (looking happy, I think), with Frisk and some of the other (more) main monsters, that can preserve through Resets/time stuff. So I do think it is decently possible, that Sans is trying to remember Gaster and/or others/other stuff; trying very much to cling to that/them, even while it causes him a lot of despair and grief (at times). Like in his Lost SOUL dialogue. And so on.

Woah really?! It's almost like that's not related at all

What if out of screen sana dies like fatal hit from deltaruns (unused animation of fatal hits that kill. By bug could be used by snowgrave on cheese on early versions)

LIES. Comic Sans is a fantastic font. It is easily readable in general, it is accessible to people with reading issues, and it is easily accessible on devices. Papyrus is great for titles, especially if you're using it for something related to Asia Minor and North Africa. Accepting no slander of these iconic fonts /light-hearted but genuine

The cofirmation is that if you talk with cinfidence about lies, no one will tell.

Wasn't there a badge and photo of sans happy with other people

Erm if you are a DF expert you know that the drawing shows chara, asriel, and harlow ☝️🤓

And?

@@user-KNP13 Nah it was just to do the comic nerd, wich wasn't funny...
