#UTDR theory

[humunanunga]

hold on... okay... ...so what if...

so this might not be what's happening, but could you imagine... if the reason the prophecy is so specific about some details, but vague in others... is because it's been a recurring cycle. another turn of the hourglass before the sand stops pouring.

what if what happened to Dess... was because she was the previous girl to be sacrificed to its fulfillment...

...which, if Dess is the Knight...

[dead-in-a-damn-ditch]

i just realized. there are no humans in undertale or deltarune that explicitly use he/him or she/her pronouns. frisk, kris, chara, and the other 6 human souls all use they/them. who's to say humans in these games even have gender as a concept. maybe gender is specific to monsters

Noelle but she’s praying to be forgiven for what happened during snowgrave

Originally Kris was supposed to be in the drawing but I hated it

The Only Human Document

Hello. For the past few months I have been working on a document deconstructing the dynamic between UNDERTALE's protagonist and the various factors surrounding them. After replaying the game I've had a revelation of sorts regarding this topic that I'd like to share with you.

For theorists in this community, I only hope that this proves useful going into DELTARUNE.

(View The Only Human document here)

My Deltarune / Undertale conspiracy theory is that Chara fell into the Underground on December 25th, 201X.

End of 201X? Doesn't refer to the decade, it refers to the end (i.e. last month) of an unspecified year in the 2010s. The emphasis on Christmas and Winter with Dess and the Holidays? It's all going to connect babyyyyy

Why the May 2025 Deltarune Newsletter Heavily Implies the Existence of a New Weird Route

new newsletter, rejoice! alongside some cool new info regarding release - specifically timezones and consoles - we also got some new information which i strongly believe implies the existence of a chapter three and/or four weird route. let me explain!

so, this begins with toby's reveal of the playstation trophies. unsurprisingly for a meta game element in deltarune, they seem to be written by the GONER_MAKER voice, or probably-gaster.

notably, one of them, the chapter 3 end trophy, has this description:

this trophy is also pretty special, as toby has something to say about it:

i believe these two small details are hints towards the existence of a new or continued weird route.

i know that's absurd to say from just that, so let me explain! from those two bits of information we can extrapolate four criteria for these "certain conditions."

they provide an alternative manner to reaching the end of the chapter

they are, to some degree, secretive or obscured beyond what a casual player would experience

they are not a bug as toby is calling attention to them before release

they are something that probably-gaster would consider an issue

now look. i have really really tried to think of anything that could be being implied here beyond a weird route because it feels so out there, but i simply cannot think of anything that makes any more sense and fits the criteria. therefore, i'm going to call it. chapters 3 and 4 will likely have at least one weird route, whether that be as a continuation of the chapter 2 route or an individual new route.

if you can think of anything else please feel free to bring it up in tags/replies/reblogs!

Not much of a "theory", but it's possible that the Mayor's name is Clarice, after the love interest seen in the original Rudolph movie.

If true, the mayor herself would fit within the outcast theme in Deltarune, as she would be the only Holiday family member who's name doesn't fully fit within the Christmas motif.

The Mayor Knight Theory

I'm not used to writing long-form posts but I've spent years talking to my friends about this theory that only 2 or 3 other people seem to share so I'm putting it out here, too!

My theory is that the Knight is C. Holiday, the mayor of Hometown and Noelle and Dess' mother.

The Importance of the Holidays

Aside from the joke of Loox' name, the Dreemurrs and Holidays are the only characters so far to have canonical last names. This might not mean much on its own, but Noelle has clearly been set up to be an important character in Deltarune.

Her sister is missing. Her father is sick. She's childhood friends with Kris and has a crush on Susie, and studied the occult with Catti. She's in concept art of the Fun Gang, and along with Susie and Kris, is the only other name that earns the response "YOU ARE ABOUT TO MEET SOMEONE VERY, VERY WONDERFUL" by the opening narrator (metatextually implied to be Gaster himself) if you name yourself after them.

Her mother is mayor, and is planning the upcoming festival. We know next to nothing about her, except that she's cold, strict, and possibly planning to evict Asgore if the note in his room is anything to go by.

You have one month. - C

It's clear that Noelle and her family are important characters. But how is her arc going to continue?

Cyber World

Queen seems to represent Noelle's mother, with the climax of the chapter being Noelle finally standing up to her after being ignored the whole time.

Queen's goal is for Noelle to create another dark fountain within the dark world itself: something she refers to in her fight:

Focusing Into Her Blade, She Will Create A Neo Dark Fountain

During the Spamton Sweepstakes, on the page /chair/, it depicts the chair in town hall with the tab text

But what if it could... ...get darker than dark?

Parallels of Noelle and Chara

Noelle has heavy angel symbolism, from her dress, to the doll she and Dess made for church. She wears a ring of thorns in the Weird Route, and Spamton repeatedly refers to her as [ANGEL].

The two angels of the original Delta Rune legend in Undertale are implied to be the Dreemurr siblings, with Asriel breaking the barrier and Chara (entirely with the assistance from the player) killing a good portion of the underground.

Chara thanks the player, saying,

Together, we eradicated the enemy and became strong.

Throughout the Weird Route, emphasis is placed on Noelle becoming stronger, text affirming "Noelle became stronger." with every fight.

Asgore was brought into a vengeful depression with the death of his children, seeking to both take revenge on humanity and save monsterkind at the same time.

If the Knight's goal is to bring the Roaring, something the Prophecy seems to call the Angel's Heaven, who's to say the Knight isn't also acting out of grief? A world that could protect her remaining daughter?

The Significance of Very, Very

This one is admittedly a bit of a stretch, but it's still interesting (ha) to me.

The exact phrasing of "very" twice calls Gaster to mind, with entry number seventeen/room_gaster saying "VERY, VERY INTERESTING", the mysterious messages on Twitter with a similar speech pattern saying the same thing, and the opening narrator with typer ID* 667 (room_gaster uses 666) calling Kris, Noelle, and Susie "VERY, VERY WONDERFUL"

Otherwise, the exact using of "very, very" is used sparingly in Deltarune, the only examples being Spamton telling Kris how to use the Loaded Disc,

THEN. KRIS. AFTER. THIS IS VERY, VERY IMPORTANT.

Throwing away the Ball of Junk in the light world, which represents Kris' dark world inventory,

You have a very, very bad feeling about throwing it away.

And the mayor's secretary, when asked about her.

She's very, very busy preparing for the festival.

Maybe it ultimately doesn't mean much, but with the importance of the other two examples, I think it's worth considering.

The Future

Chapter 4 is all but confirmed to take place in the Church. Service is the day after Chapter 2, according to Rudy.

Might even be able to go to church tomorrow.

If this is the case, it's likely the story around Dess will be expanded, and with that, the rest of Noelle's family.

Conclusion

At this point in the game, at least to me, this option seems to make the most narrative sense. I know we're only a small bit into the story right now, and the Knight's identity is anyone's guess, but I thought I'd share a candidate that a lot of people seem to be skipping! ^_^

*typer id in undertale + deltarune is a number attached to a collection of soundbytes. if the soundbytes a_1 to a_6 attached to typer id 3, a character speaking dialogue with the typer id 3 would use those soundbytes

[charafansmile]

Going through the undertale encyclopedia and was reminded about how much i love this line.. hes gotta be talking about gaster here right??? Cause it makes no sense for him to be talking about flowey since he's not met flowey at this point in time (at least as far as HE remembers. Floweys met him plenty.) And yeah sure he could be talking generally like flowey does at the end of pacifist ("there's alot of floweys out there") but the phrasing and emphasis put on it feels intentional (like most things in these games do..) and we have very little information on why gaster is sharing deltarune with us (afaik. Gaster heads feel free to chime in) so my thinking is that his 'goal' with deltarune will quite literally be curiosity and scientific desire (perhaps originally it was something else, much like how charas original goal was to free monster kind and became a desire for power)

Most of my interpretation of gaster comes from his little speech here. The rest are much more baseless and headcanony- such as the very specific belief that gaster is going to mirror kris in some way. kris wanted to be a monster so I think another 'goal' of gasters ( if it isint just curiosity about us as an eldritch being hes studying) will be to become 'human'. Not in the way kris or frisk are human, but in the way WE are human. Able to affect the world on another level. Jevil looses his belief in reality when exposed to the truth, and spamton tries to reach above and move onto 'heaven' so If gaster knows about us because at some point he also learned the truth of the world then I'm thinking that each of the next bosses will in some way mirror his decent into where he is now(wherever that is). Think each secret boss being a step in the cycle of grief except it's not grief and theirs seven steps and it's all a reflection of this one's guys mental breakdown that he's either over or still experiencing. So I'm like 80% positive the next boss is going to be the 'type' of person sans describes in his no mercy speech. Or the one after that.

WHY IS NO ONE TALKING ABOUT THIS

[humunanunga]

I haven't seen any mention of this yet, but if you count the windows, there's 51. There's not a FUN event attached to that, afaik... but:

if we assume there's one missing, 52 is the number of playing cards in a standard deck– jokers notwithstanding.

...but...

if you recall there being a track in Chapter 2 called Digital Roots, a digital root is when you add up the digits until you get a single-digit number: 66 = 6+6 = 12, 1+2 = 3. It's sometimes used for puzzles, like in 9 Doors 9 People 9 Hours, but it's also prominent in numerology– numerical divination.

51's digital root is 6, which could make it a candidate for signifying correspondences between Gaster and Spamton.

51 = 17×3. Gaster is associated with Entry no.17 and I noticed 3 as a recurring multiple or digit. Dog with maracas only occurred for me behind windows 3 or 30-something, unless I miscounted.

so you know how Gaster's number is strings of six and Chara's is strings of nine.

ROOTS is through window 36, which equals 6×6, is divisible by 3, 6 and 9, and has a digital root of 9.

Therapy is through window 18, which equals 3×6, is also divisible by 3, 6 and 9, and also has a digital root of 9.

3, 6, and 9.

9 being 3² and 36 being 6².

Given this uptick in religious themes, I wouldn't be surprised if we'll be referencing more numerology to solve these mysteries...

((yap session/theory

((i think. personally. the main antagonist is gonna be A. asriel/ralsei twist villain B. sans + papyrus twist villain OR its gonna be like. a truth vs ideals/ two points kinda thing, where both sides have a point but you have to pick. i have reasons under cut but nobody is allowed to call me crazy

((i just feel like it being JUST gaster in the end would be sooo predictable and obvious, like. omgg guys scary shadow mystery man is bad . like what.

((currently going with the two points one as my main theory for several reasons. such as but not limited to 1. “who will miss him” (“him” is used to refer to asriel and gaster(?) in undertale, but ppl would obviously miss asriel, he’s a really popular and well liked guy in hometown. gaster however (a lot of assumptions here) seems to be a kinda shut in bunker in the woods type guy.) since we know “papyrus is busy” (and he is labeled as “forgettable” in the ut genocide description, plus a very accepting and forgiving guy) i would assume he is going to be the one looking for him - because he cares about everyone and sees good in everyone. sans isnt looking, however, making me think that gasters more of a morally gray character? and asriel/flowey seemed to have very a black and white moral compass (to me, which is debatable). leading me into my next idea/point

((asriel is using gasters soul as a save point to play videogames with kris. first of all everybody realizes ralsei is the only darkner who can travel between dark worlds with the gang. second is eye colors. we see several reoccurring patterns with colors and souls and eye colors, the main ones im reffering to are sans (cyan/patience + yellow/justice), IMAGE_FRIEND/spamton (magenta/perserverence + yellow/justice) (and jevil just has yellow eyes (justice)). i think (big leaps here) image_friend is papyrus, who has magenta/yellow eyes (in opposition to sans’ cyan/yellow). this would mean they have yellow in common, which i think is . gasters color. (along with indigo or purple maybe (magenta+cyan))

((also think its his color bc of the egg thing.*

((yellow is the save point color in undertale, but not deltarune. which wouldnt make sense, except cyan yellow and magenta can make either black or white depending on whether its print media (light world?) or digital media (dark worlds?). this could also be me connecting pieces that dont fit, so take with a grain of salt of course.

((*the egg thing is big for me but i could also be insane for it. first of all. hard boiled?? wont hatch but leaves due to happiness. i think that will be gasters good ending, however that plays out. on the other hand,

((have u guys ever heard of shocking a hard boiled egg in ice water before u peel it?? iceshock Is one of noelles attacks. i think the weird route/snowgrave will be the one where u fight gaster in the end. this is another reason i think gaster will either be good or morally gray - you have to be a total dick thru snowgrave to fight him. these last two points may be seperate from the main one, not sure.

((anyways this has been wdg mod throwing sketti at the wall. i may add onto this or scrap it entirely

I mαde an updated suselle analysis doc on why I think they’ll be canon 4 sure so yah!

DELTARUNE - Debunking the "FRIEND"

Something I've noticed after being in deltarune fandom spaces after Chapter 2 is that there's a pretty big fixation on the "FRIEND", which has always seemed a bit... off, to me? But, based on a few recent findings I feel very confident in saying that the "FRIEND" is, beyond a reasonable doubt, not an actual new character. (Afterthoughts under the read more)

So, here are my afterthoughts:

Calling this a "theory" is a little disingenuous seeing as most of it is just compiled 'objective' information, but I really hope that people begin to understand the nature of the basement smile a little more. This is kind of an image I put together at like 5 AM after a night of theorizing with like 3 people on discord so it might be a little rough around the edges. Obviously the "angry" parts of this were heavily exaggerated for comedic effect, but there are a quite a lot of theories based on the idea of the "FRIEND" being a character that exists, and a... LOT of fanworks, but it kind of just distracts from ACTUAL mysteries in UTDR that could be being solved or at least discussed.

It's a little bizarre looking back and seeing this sort of mythos built around the "FRIEND", stuff like it being a cheshire cat, it being Mike somehow, and it being heavily relevant in the future chapters of deltarune. Stuff like the friend being a "cheshire cat character" or even existing isn't really mentioned at all in deltarune and has quite a fragile basis when you look at it without already assuming it's a character, but people have clung to this idea and projected these ideas onto official content (cough cough mystery letter) to the point where I think the future chapter releases are going to be very jarring for people who EXPECT an answer to a mystery that doesn't really exist.

Anyways, I'm not too good at ending these things but I'll cut off my ramblings here.

[chestersbraincell]

What if Chara and Kris ARE alternate versions of each other?

What if Chara’s name IS actually “Kris”?

What if their name being Chara really WAS a huge misunderstanding of the pun of the menu saying this was the “TRUE name”(ie short for “character”).

What if the way we can choose their name ties into us being able to choose OTHER aspects of them in Deltarune, atleast before our choices are “discarded”.

What if this fact alludes to the fact that Undertale was very much supposed to be a prototype to Deltarune of sorts(ie, we can hypothetically only choose their name whereas in Deltarune we WOULD’VE been able to choose more things about them)

What then.
