SANS IS A DARKNER | Undertale + Deltarune Theory

[@2leftthumbs]

A super common argument against I'm seeing, has to do with Sans ability to dodge (31:50), and how I compare that to the Darkner's dodging. Many have pointed to Undyne discussing their fight with Asgore: * Once, to prove I was the strongest, I tried to fight ASGORE. * Emphasis on TRIED. * I couldn't land a single blow on him! I have two possible arguments against this. 1. When a monster attacks our human hit box, we can move around inside it and dodge their attacks. Yet no normal monster seems to have this ability. However our attacks are represented from a monster's perspective is not something they seem able to avoid. If that is the case, then perhaps monsters can dodge other monsters, but are either unable (or have not yet learned how) to dodge human attacks? Sans is atypical: either a Darkner with the dodge ability, or simply a monster able to exploit other abilities like time travel/ space manipulation. OR 2. One theory is that Frisk is able to dodge, not just because they're a human, but because they have Determination. It has been speculated that Asgore is able to utilize his Red Trident (thought to be infused with Determination) to dodge! I share these not to tell people they're wrong, or to discourage others from sharing! I had just typed out these arguments about 5 separate times, with 100s of comments left to read, and figured a pinned post would be more useful. Please, feel free to poke holes in this! That's what this theorizing is all about :) Thank you all so much for watching, sharing, and leaving your lovely comments!!

You said that Lightners appear to not use magic. But susie uses magic in the dark world.

It is unclear if Susie is using magic, or if her axe is magic. If she is using magic herself, it is a product of the Dark World. There are no examples of Lightners using magic in their own world.

TWO THINGS (one debunk and one observation) 22:35 Toriel’s red eyes were a mistake made by Toby spriting. In the Kickstarter files when Toriel is holding a pie, it’s the same red as her eyes on the entire black background! When Toby must’ve recolored it, he must have forgot the eye color! Do you remember that crossword Sans had? It’s Ice-E’s. There is no Ice-E’s in Undertale. However there is an Ice-E’s in deltarune. And isn’t it convenient how the crossword looks like a kids restaurant activity?

[@2leftthumbs]

I checked on the Kickstarter image, and the actual game files. It appears that yes, without any lost resolution or compression, both images use hex #400000. Good catch! I don't know precisely the workflow for sprite creation. But there is a chance that is where the red eyes came from! 19:46 covers the Ice-E puzzle. I understand that it's a long video, and it can be easy to miss something that I only spent like 10 seconds on. Just glad you agree that it likely has some significance ;)

One more evidence that Sans in UNDERTALE comes from deltarune (or vice versa): The sprites files of characters in deltarune looks different from those in UNDERTALE. Even for those characters who looks similar in two games, the sprites are redrawn deliberately. For example, the sprite size of Toriel is edited slightly, so spr_toriel_school in UNDERTALE and spr_toriel_d in deltarune cannot fit at all. Sprites of Alphys are called spr_alphys_d/l/r/u in UNDERTALE while changing to spr_alphysd/l/r/u in deltarune, missing the "_" in filename. The only two characters whose sprites remains the same in every way are Sans and, interestingly, Onionsan. Could that be related to the fact that they both talked about the nonexisting "tomorrow" with Kris?

[@2leftthumbs]

That is incredibly interesting, and I haven't seen it mentioned anywhere else! Thank you for that info! I was interested to see what Onionsan had to say in the hypothetical "tomorrow" that we'll see in full game, but I hadn't put tooo much weight in it. The unedited sprites, combined with the links of "tomorrow" has me all the more excited to see what is being built towards!!

“Monsters don’t know what actual blood looks like” Six humans who fell down: am I a joke to you?

[@2leftthumbs]

I don't know for sure, but it seems like Asgore disposed of them quietly, hiding that from other monsters. If anyone were to know, it'd be him - but very few others. Certainly not your average underground citizen! That's my take on it at least.

[@pineforest1442]

Two Left Thumbs I don’t know. I feel like some of the bosses (what I call the main nine) had a bit of a hand in killing the kids. Undyne straight away tries to murder Frisk and take out his/her soul to transport to Asgore, instead of bringing them there to be killed by Asgore himself, and Sans may have had a hand in the deaths of someone before promising Toriel to leave them alone. But they never bring Frisk to the castle for execution, they do a kill on sight thing, which may have been there before Frisk fell. So I am pretty positive that most of the monsters know what a human looks like, not just because they have seen the kids, but because they may have books on what humans actually look like (seeing as their obsessed with humans and the war, even going as far as to have some of the puzzles mimic the sight of a human’s soul breaking), and would probably even figure out that humans *bleed* and knows what human blood looks like. Even the tiniest Froggit is likely to know what a human looks like. Plus, one thing I like to add is Papyrus probably doesn’t bleed in front of you because you knocked off his head instead of slashing a blow right along his ribs like you did with Sans. Bit of food for thought on that one.

Deltarune Chapter 2 does kind of shoot this theory in the head though, as Darkeners like Lancer and Rouxls both turn into inanimate objects (playing cards, in their cases) in the Overworld, whereas Sans doesn't. If Sans was a Darkener, that would mean that the Underground (the setting of Undertale) would also have to be in a Dark World, which _could_ _maybe_ be true, but there's no evidence to support it. Furthermore, Ralsei, who is presumably a Darkener and not the Dark World version of Asriel (as he is in college, not hanging out in the Dark World), has an HP bar, so Sans not seeming to have one proves nothing.

[@relicmusicofficial]

Ralsei may or may not be a darkner, since we never actually see how or when he transports to the library dark world. If he's able to teleport, presumably he can also teleport to the surface world. If he traveled to the library dark world by traversing the surface world, then he's able to get to the surface world. We can't really make accurate assumptions as to if Sans is or isn't a darkner without fully understanding Ralsei's mystery first.

Asriel might actually be Ralsei. In chapter 2 dont you think its weird how Ralsei never turned into stone despite being away from the castle?

Holy shit, so I was rewatching this theory, and I had a sudden realization. Sans doesn't show any skeletal features outside of his face. Everything about him is covered. He wears mittens, lengthy socks, and a sweater. Not only does Sans' physical appearance look similar to Lancer's and Chaos King's, but their faces are almost identical. The realization I had was that when Lancer joined your team in deltarune, he physically altered his face. I never gave that much thought as I always just laughed because it was hilarious, but think about it. Sans could look more like Lancer than we realize, just covering himself completely and altering his face to appear skeletal. He wouldn't even have to alter it too much because of how similar it already is. Another point that Sans isn't a skeleton, is because when he's hit and bleeds, the wound isn't something a skeleton would have. The blood would be coming from individual ribs and bones, but instead it's one long wound, like you would see on a Darkner or Human. When Papyrus is struck, he doesn't bleed at all. Look back to Papyrus, he's visibly a skeleton, even with his "battle body." his limbs are bone-thin and his spine can be seen visibly attached to his head. Take this point with a grain of salt, but Sans' appearance in Smash is an interesting one. Look at his feet and legs. They do not look skeletal like Papyrus' at all. They look like Lancer's, human's, or anyone not a skeleton. Sans does use skeleton attacks, but they are slightly different from Papyrus'. We also know that Papyrus' attacks can be taken and stored (think the sink, box, and Undyne's drawer). So what if those attacks aren't even being summoned by Sans? What if he just took them from Papyrus? They both have Gaster Blasters (Papyrus implies), but these seem more like technological weapons than magical. Really, their only true similar power is gravity manipulation. But that, too, could be more scientific than magical. If this theory is true, it just changes how we've viewed everything before, and I love it. It's made me rethink everything I thought I knew about these characters. I'm completely convinced, but I'm keeping an open mind. TL;DR: Lancer can physically alter his face, and that's the only thing visibly skeleton about Sans. He could actually look more like Lancer than we think, and he's just altering his appearance to be skeleton.

Hey sorry i'm late but I have a theory about something in Undertale that only comes up once. When you go to Sans & Papyrus's house, there is a sock on the floor that has note from Sans and Papyrus. You probably know what I'm talking about. The reason Sans never picks the sock up is the same reason going to the surface doesent apeal anymore. His knowledge of Save files and Resets tells him that it's all going to end up where it was. Sans doesn't really apeal to going to the surface because he knows everyone is going to end back up trapped underground. The same with the sock. If he picks up his sock and brings it back to his room, It'll just end up back down on the living room floor. So, in short, the sock on the floor represents Sans himself.

Your mention of Sans and the "little brother" comment got me thinking, is Lancer's connection to Papyrus stronger than Sans's? Lancer's role in this game is extremely similar to Papyrus's role in Undertale. To make a few bullet points: - Both are initially presented as antagonists, but are too soft to actually cause serious harm to the player. - Both are working for someone who actually wants to cause harm to the player. Papyrus has Undyne and Lancer has the Spade King. - Both really want to make friends. Papyrus was quick to make friends of everyone around him even if they were supposed to be an enemy. Lancer initially warms up to Susie while eventually warming up to the rest of the cast. While many enemies end up making friends for the player, Papyrus and Lancer are particularly proactive in making friends, more than any other non-playable character. There are probably more examples, but their roles in the games were both very similar. If Lancer is some form of Papyrus in this game, it wouldn't be surprizing if San's little brother comment was actually referring to Lancer. It was very weird that Papyrus is one of, if not, the only major character to not make an appearance in this game in some form, unless that form was Lancer.

sans in the fight says "i gave up trying to go back long ago" and we assume he means to the surface. but then, his next line is "and getting to the surface doesn't really appeal anymore, either" implying that going back and getting to the surface are different things the "either" in his second statement is really the part that makes it stand out; if he had given up trying to go "back" then him stating that getting to the surface doesn't appeal either is redundant. essentially, the and and either statements imply these are two separate topics, and that he gave up on returning into the deltarune universe. which leads into a somewhat different theory, that deltarune is in the past. we already know that the games both have connections to time and space; focusing on the time part, maybe deltarune takes place in the past of undertale? In deltarune toriel acts exactly the same, mothering kris heavily. in undertale, she finds frisk and "adopts" them, teaching them about the game. asgore in deltarune looks possibly like a pre-king version of his undertale self. the gaster doors below the church area in deltarune may imply that gaster used to be a darkner/deltarune character as well, before moving his operations into the underground. alphys is a teacher, maybe deciding to move into the field of science sometime between the games. undyne has both eyes, implying that maybe she hasn't lost hers yet. if sans is truly saying that he gave up trying to go back to the deltarune universe, it definitely means that undertale takes place after deltarune. side note: the relation between sans and toriel (as you mentioned) and them recognizing each other could be a reference/callback to "i already 'befriended' your mom last night." It would make sense, as they both feel they recognize each other but so much time has passed that they don't remember.

Could be that he's got some work going on down there! The connection with Sans and Toriel is really fun. I think that's a good catch! Here's an interesting thought. The sound we hear near Deltarune's red door needs it's tempo changed by 666% to sound right. What if time in these different worlds moves differently? ie.

Why would it just randomly start leaking from his mouth? It seems more like blood haemorrhage to me. Another thing: it takes a few seconds for the blood to appear after Sans is struck.

i like how Game Theory with Undertale is often more speculative, but still with evidence, and you're going off of cold hard facts with some speculation, which is what's likely to be true. (i mean, nobody REALLY believes that Ness is Sans.)

[@tb.7788]

sans being a spade is such a cool theory. also 34:45 he had come up with susie as a character before he even had the idea for undertale. he wanted to make a rpg with playing card inspired characters first (deltarune) he then had the idea for undertale and was writing both deltarune and coding undertale at just about the same time.

[@P-RiSe]

A bit of a theory here. I always thought it was possible that Sans faked his death (or at least faked a monster death). When he limps offscreen, the'monster dying' sound effect is still played.I thought he may have had a gravely injured or fallen down monster that made the sound in his place. Which monster? Shyren's manager (lower half). It doesn't vanish when the battle ends. Sans watches that fight specifically, whether to sell tickets or keep his distance with his hood up. This is the only time this happens as far as I remember. He even mentions shyen's body on the official tumblr blog under 'important info'.

[@2leftthumbs]

The monster death sounds is something I unfortunately do not have a good answer for. I've heard the theory of him faking his death there, and I do like that a lot!

@@2leftthumbs a bit to late to this but i'd like to add anyway ; the "monster death" sound-effect plays when a fight ends regardless - which means even if you don't kill them (i.e. fleeing or sparing) the sound-byte still plays. so the sound doesn't actually have any connections to monsters dusting/dying, rather just the end of an encounter.

Another thing that holds-up the Dark World being real and not a imaginative figment, is that, if you complete the Snowgrave route, Berdly returns to the light world, permanently asleep/dead. While one could argue he just passed out hard, if you take certain path of a normal run, where Berdly gets his arm/wing damaged trying to break free of Queen's control, he returns to the light world with a wounded arm/wing. Also, Berdly has a thing against Kris, so if it WAS make-believe, Berdly would have no part in doing so, due to how much he hates Kris. Therefore, with the evidence given, it's true the Dark World actually happened

[@isthatbraised]

No....that's just because Berdly is a lighter. I still it is still technically real, but its just like a simulation or powered by something far more powerful. Determination.

[@sebastianwatches7095]

the theme of deltarune is that your choices dont matter i think theres a chance berdly may wake up but have no recollection of what happened in the dark world, simply to give the player's attempts at changing things a middle finger, or the world's way of hard-resetting berdly after an unexpected thing happened

[@mmgmagic]

Actually, the designs for Toriel & Asgore were already seen in the pacifist run credits so Sans isn't the only one that has outfits shared with his Undertale. Plus, Sans would probably be too lazy to get a redesign. If anything, he would purposely take a very slight change like maybe his jacket would be a single digit up in hexidecimal colour or maybe he happens to be missing a single pixel.

[@2leftthumbs]

I had to dig that up and give it another look. That is pretty interesting that Torial and Asgore are seen with their Deltarune designs!! Hmmm. I think I had seen it brought up before, but I went looking in the wrong place. I wonder what it could mean??!

[@dyedie1]

Hey, I watched this vid a while back and it was super insightful. One more thing I'd like to add that I don't remember seeing is that the first time you enter Sans' room in undertale, it's almost like when you enter the closet to the dark world in deltarune. You're surrounded by pitch black darkness, and a fell wind(black wind?) begins to pick up in the background. Shortly after papyrus turns on the light and sans leaves a note in the room saying he fooled you, so I originally played it off as just another Sans prank, but it's too eerily similar to how you enter a dark world in deltarune for me to ignore.

[@gameman7871]

Gotta say this video was absolutely mind blowing but there is one thing I wish you had talked about. The parallels between Sans and Jevil. Both are viewed as the hardest boss fights of their respective games A major part of both characters is their relation to comedy they both have some level of coterminacy (noicy? idk how you spell it) and they have direct opposite ways of dealing with the same problem: life is meaning so do you do nothing or do anything? there's other stuff too but you get the picture, just something cool I noticed

[@2leftthumbs]

Glad you enjoyed it! Jevil seems to be very much their own thing, although some of the similarities with Sans are hard to ignore. I think I felt that if I were to fold that in as well, things would already be less focused than they already felt at times. You know? We just know so little about Jevil, that the speculation would be RAMPANT! Perhaps that's a subject for another video? It certainly makes for a good discussion though! Coterminosity, perhaps? "means that two things have the same boundaries" Not a term I was familiar with! Hopefully that's what you were getting at?

I thought of the blood thing at the beginning of this video and was going to leave a comment on it if you didn’t address it... but this seems totally unnecessary since you spent a great deal of the video talking about it! Tbh I haven’t watched an undertale/deltarune theory in a hot second so this was nice to see (especially since I just watched an undertale playthrough). Also just an added thought to the whole Sans is related to the spades family: Lancer and the Spade King’s faces could possibly be hidden, meaning that they could actually be skeletons and we simply can’t tell because of their shrouded faces.

[@2leftthumbs]

It's very noteworthy that Lancer and the Spade King appear to have hoods pulled up over their faces. It makes me SUPER curious if there would be a similar dark shroud over Sans' face if he were to pull his hood up!?

Thanks so much Kristy!

[@jackhammer4499]

My theory is that while the dark world doesn't exist, it's not PURELY a figment of their imagination either. I think the player is a part of Gaster's new experiment that lets you simulate the dark world through Kris, whether Kris knows it or not. This might also explain why Seam and Jevil are the way they are. Heck, Seam even quoted Gaster. Seam said that they met a "strange someone" or whatever and his words turned Jevil insane and Seam depressed. I think that someone was Gaster, explaining that the two of them don't exist.

[@Jevilman]

Shush. That may be right.

[@1Alchemist]

I know this video was a year ago but I haven't seen much mention of it it's a small thing but yknow in undertale, during the asriel battle when you reach out to sans and papyrus, sans says "just give up. I did. why even try? you'll never see 'em again." I always wondered about that line but this video reminded me of the whole "don't forget" thing and the photo not sure if it's proof of anything beyond what we already know from sans' monologue in the genocide run, with the whole "I can't go back and the surface isn't that appealing anymore either" thing, but it's still interesting to me :0 especially when I remember that regardless of the usage of the second person in those dialogues with the souls, they're a representation of what the characters are/were feeling this is gonna be VERY interesting once we get more context lol

[@torilila]

If you go back to the deltarune website and read faq, you will see this: Q: So there's no connections between the two games? A: It's a different world that might even have different rules. That doesn't mean there will be no connections at all though. (Dunno if it means anything.)

[@2leftthumbs]

In Deltarune, you supposedly cannot "kill" Darkners in the traditional sense. They either run away, get tired, or are Frozen in the Weird Route. If for some reason you abandon the Weird Route after getting the Ring of Thorns, there is an instance where you can use Snowgrave outside of the Berdly battle. When you use Snowgrave on a common enemy, they will dissolve into a puddle of red goo and die, and not freeze on the overworld. When you kill Sans in Undertale, he oozes red.

[@King_Luigi]

21:25 - Papyrus having a different design wouldn't be _that_ surprising though. Sans tells us himself that what we see Paps in during Undertale was simply his "battle body" that they "made that a few weeks ago for a costume party". We also see him in _two_ other outfits by the end of everything. 34:45 - "Goner" Clam Girl didn't appear until the Switch version, which was almost 3 years after that "don't forget" update. (Also, I think that's the _only_ place you can find her too.)

[@2leftthumbs]

I've thought about this since, and I agree that a new outfit wouldn't tell us much. But if there were differences in his physical characteristics, or personality then that would be much more telling! Something to indicate he lived a different life in a different world - similar to Undyne having both eyes. My mistake, Clam girl was in the original game with a specific fun value. The 1.001 patch added an interaction with her that affected the contents of Sans drawer And the Switch version is the first appearance of Goner clam girl. So she has a long history of being significant, with more and more layers being added to that - but I didn't do the best job laying that all out clearly in that section.
