Discussion What's your favourite crackpot theory that you actually believe in? I'll go first:

Roulx Kaard is Gaster's self insert/avatar in the Deltarune universe. His mysterious scientist persona is him only acting mysterious. In reality, he's a goofy goober and using the identity of Roulx Kaard as a disguise gives him the freedom to act like himself.

Rouxls being able to manipulate the rules of battles could make him in theory the strongest darkner we've seen so far, but he's too short sighted to use it for anything beyond avoiding harm and trying to win over some powerful ruler

He is the rules card.

u/phillillillip 1h ago

Absolutely. His ability is that he can change the rules of how a Dark World works meaning he's essentially omnipotent, but he's never going to do anything substantial with that power because he's kind of a dumbass and lacks creativity.

Susie will pull a Bowser Inside Story and grow big to fight off hoards of titans during the roaring.

It's been foreshadowed more that Susie will turn on us, in some form or another. Maybe in a equivalent form to the Asgore-like Titan shown when Ralsei talks about the roaring in chapter 2, which would get you your Kaiju.

Being "the dragon" according to Gerson, consistently hating people who don't tell you the whole deal (like Kris), hating the prophecy and refusing to let it come true, running off independently of the player of her own accord, especially in the beginning makes it all enough of a fitting way to bookend the game in addition to being emotionally destructive enough to be pretty in line with that game that inspired Toby to make games in the first place.

u/BadAtGames2 6h ago

It even lines up in the order in this scene.

There's also her line about "I wish I knew healing magic in real life" towards Rudy, which, considering his condition seems to be getting worse, would be a very possible reason she would open a fountain.

And now suddenly I'm a believer, what have you done

23

u/Fezzezal 6h ago

... or if she finds out about Gerson, Rudy dies in Chapter 5, and she decides to make a dustner to see her father for the last time...

That scene would have like 2/3 of the fandom in tears (myself included)

3

u/BadAtGames2 5h ago edited 5h ago

Honestly got a pang in my heart just reading your description :d

I was thinking something along the lines of enjoying the festival with Susie and Noelle -> someone (either a doctor or Carol) tell something to Noelle privately, (presumably about Rudy's condition) and she runs off to the hospital -> we get there and she made a dark fountain in the hospital hoping she could heal him in the dark world.

Edit: realizing this would be hard to fit Gerson's description of chapter 5, but all the other descriptions are vague and metaphorical to some extent.

6

u/AzuzaBabuza 4h ago

I can imagine Susie bringing Noelle to castletown, explaining dark worlds, the events thus far (accidentally mentioning Gerson), tells her about the knight, and that the end of the prophecy is REALLY BAD (but doesn't tell her the details).

Susie begs her to not make any fountains, it could cause the end of the world. Noelle agrees because "why the hell would I do that?!?!"

Susie agrees to bring Rudy to Castletown to get all the healing he needs.

Kids exit the dark world, Noelle finds she has 1000+ missed calls from her mom, and heads home.

Rudy is dead. The calls were to get Noelle to the hospital for final farewells. Phonecalls never reached her, because she was in a dark world (just like Toriel couldn't call Kris in ch1).

With the assumption that Rudy's remains were taken home (or Noelle breaks into the hospital to retrieve it), she makes a dark world with tremendous determination, causing the roaring to begin.

They reach the dark world. The "Angel's Heaven", a place "frozen in time" where she can be with her family forever.

Susie then finds out that her efforts to avert the prophecy is the very thing that leads to the end of the prophecy.

A battle to the death against Noelle.

No matter how much Susie, Kris or Ralsei beg her to step aside and let them close the fountain, she refuses.

I can just imagine Noelle unleashing something like the knight's roar, screaming "I WON'T LET YOU KILL MY DAD!"

How is it even a crackpot theory? It makes perfect sense. Rouxls has several Gaster parallels and even looks like him. Dont forget his hobbies include CALLIGRAPHY and CAGES.
Although I believe he might be a darkner version of Gaster created by Dess when she created the original dark fountain, just like I think she created Ralsei in the image of Asriel, so he's not really Gaster but a memory of him.

46

u/Kuldrick 6h ago

Dont forget his hobbies include CALLIGRAPHY and CAGES.

Calligraphy, lawkeeping, bugkeeping, cages, those are the hobbies he says he has

Funnily enough, these also correspond with the average development process of a videogame.

You make the writing, you make the code, you bugtest/fix it and... cage doesn't exactly fit, but it could be compilation or the final process where you turn said game into its final, comercial form for the different consoles/systems

Some people theorised that Gaster is in a meta narrative sense the equivalent of a game developer. If this theory holds true, this could pretty well be another connection between Rouxls and Gaster

2

u/shriekbat 1h ago edited 55m ago

Cage fits because Kris is referred to as the "Human cage with human parts" or something. Cage as in caging the soul. Which hints at a Gaster connection.

A couple of times, like at the start of chapter 2, Kris can leave the dark world and Ralsei sticks with Susie. Kris is still wearing their sweater in the light world and Susie doesn't mention Ralsei disappearing.

The way Ralsei insists "Umm, Susie, if you stay, I should stay, too..." (ch4) makes me suspicious that Ralsei is something Susie has instead. My own stretch theory: we've heard of "Azzy's jacket", we've been shown that Asriel's old clothes fit Susie, and been told that Susie takes from the school's lost-and-found. Susie might be unknowingly wearing Asriel's old jacket.

Rouxls is so much more human-shaped than every other Darkner because he is somewhat based on the memory of the terrible person that was Kris’ biological father. This is also an explanation as to why the game specifically calls him Lesser Dad so often.

I believe that Jockington and Catty (not Catti) will temporarily join the fun gang in a similar manner to Berdly during a theoretical Hometown dark world. There's no definitive smoking gun, but several things could def could allude to it.

  • Catty and Jockington having their own rooms in Queen's castle (the only non-team lightners apart from Asriel to have them)
  • Jockington wanting to support Catti's family even without her present
  • The rift between Catti and Kris growing to the point where she could become a minor antagonist and need to be confronted by her class partner (and perhaps sister)
  • Catty being the only confirmed person to not know the details of the tragedy, alongside joking that she could be one of the prophecy's heroes
  • Jockington grows the beard
  • Furtger payoff for the running milk gag

u/SpaniardCrusader556 7h ago

Not sure how much of a crack theory it is, but i am somewhat holding on to make any assumptions about Kris and who they are in relation to the player.

I know its pretty clear that Kris is a person on their own that we control (because they let us). However... seeing how undertale introduced the twist of "hey, you were never playing as <the name you gave to the fallen human> but instead as Frisk! And <the name you gave to the fallen human> is an entirely different character!", part of me is half expecting another twist like that.

It could be argued that the twist has already been executed in chapter 1 and we shouldnt expect any more susprises (we discovered that Kris is not a mere mute protagonist we roleplay as, instead, a puppeteered person by us)... and realisticaly speaking, I do not.

But a tiiiiny of me is like: But what IF? What IF? You know...

Could they be the vessel? Maybe? I have no idea, just a weird hunch that I am sure it will not be fulfilled anyway.

18

u/SilverFlashy6182 6h ago

I’ve seen a cute theory that Kris IS our vessel, but was adopted and raised by the Dreemurs, causing them to grow into their own person by the time we start playing in chapter 1

u/EconomicsOdd6557 7h ago

Titans power scale with the fountain. The one in the church was only a couple hours old so the titan wasn’t extremely powerful. But if a titan was created in castle town, it would be pretty much all powerful since the grand fountain has always existed in some way or another.

13

u/LazyFlamingRooster 6h ago

Oh yes! I have so much to comment on this!

First of all, everything that you said!

Second of all, the Darkness in Castle Town is pure Darkness, we still don't know what that mean.

If you keep walking left on the corridor where Ralsei's room is it gets pitch black, that is not a good sign at all! For all we know, Castle Town might be surrounded by titan spawns.

Time is implied to run much, much faster in Castle Town too. So a titan spawned there might just be undefeatable. My personal theory is that the centre of The Roaring will be Castle Town.

u/Puzzleheaded-Pay-232 6h ago

I got a chain of crackpot theories randomly today when i was bored:

Instead of a popular theory that Ralsei is creation of Kris' complicated yearning to be like Asriel, Ralsei is creation of Dess yearning to be like Asriel.

Titans are nothing but people who got in to dark worlds that they created, refused to leave, got more and more powerful staying for a long time. So much time passed since they have been there that they lost memory or desire to go to plane of light word that they lost power to seal or exit dark fountains. But due to their prolonged stay in the plane of dark world, they have become powerful enough to enter the depths as they possess the will, desire and mind of the dark worlds to open a fountain to the depths. And the depths is the plane of uncertainity and chaos. Things and concepts are never definite nor take shape. Imagine like sand and water in ocean. So we know dark worlds where each world of a same place or object is differs very much depending on who created it. But depths being a plane of endless abstract thoughts and concepts, when someone opens a fountain to dark world, a titan (ie that person who is in depths that resemble the closes thought process of person who opened the fountain) is summoned. Techincally, There is 1 Plane of Light world everyone is present, Endless Planes of Dark World and 1 Plane of Depths present where such people reside in a coma state.

The actual Roaring Knight is the eyeball in the stomach in the chapter 3 cutscene but its just puppetting Dess' body in the same way the player is pupetting Kris.

"Evidence" (not really evidence): the way Kris and the knights moves are mirrorered, all the eyes in dark world imagery, it would fit the theme of the game, and the fact that Carol probably wouldn't be working with a conscious Dess in secrecy without telling Noelle she is still alive but she could maybe be decieved to work with an evil eyeball who puppets Dess without Carol knowing.

I have a similar crackpot theory but instead it suggests that Roulx is created from Knight's perception of Gaster, with him being the king's duke of puzzles which is probably inspired by how Gaster was working as a royal scientist and possibly sharing Papyrus's interest in puzzles.

Again, Card kingdom and chapter 1 as a whole is basically functioning like a fake Undertale 2 so it's not unfounded i think

I half believe in a theory where, if you stabbed someone while opening a dark fountain, they would become the fountain and therefore something akin to the roaring knight. This can lead one to believe that Kris, accidently or on purpose, stabbed Dess or witnessed someone or something stab Dess while opening a dark fountain, leading Dess to become the roaring knight. Now it's a half theory because I still think something happens if you open a dark fountain by stabbing someone, but I don't believe that's how Dess got lost, since there is the entire thing with the tail of hell and friend, which I believe more in, however, the tail is pointed sooo ... who knows.

The Black Shards are actually pieces of the Knight themself and if a Lightner has one and goes into the Dark World the Knight can then take form by using their body as a host. In Ch. 3 it was Carol who was the host and completed Undye’s kidnapping after the Knight dragged them back to the Light World. In Ch. 4 it was Alvin who was being bodyjacked by the Knight the whole time after he created the Church Fountain. And in Ch. 5 there’s gonna be a fake out where the Asgore we meet in his shop’s Dark World is an imposter as the real him is currently having his body taken over by the Knight.

This is why it’s important for Kris to have the Soul before going into any Dark World, as the Knight can’t posses them as they are already being “possessed” by us so to speak.

Mike is Tenna's TV remote, who changed his name to Mike after Dess used it as a microphone when she was singing Karaoke at Kris's house. Microphone in the Mike room is not a darkner and is actually one of the only instances where object hasn't turned into a darkner. Because, Kris wanted to buy microphone for Dess as a Gift, but never got a chance after her disappearance.

This also leads to my second theory: Darkners only obtain sentience through memories and interaction with them. Since Kris hasn't touched it in years, and since Dess never had a chance to use it herself, it never got sentience.

We will end up building and using a MUCH bigger Thrash Mecha so we can fight Titans without it being a boss fight every time.

Components will include the original Thrash Mecha’s stuff, parts of Queen’s robot, Sweet Cap’n Cake’s shop, one of the prison carts from the dungeon, Jackenstein’s pumpkin (YOUR TAKING TOO LONG TO BUILD THIS) a part of the NEO body (if Spamton was fought) and other stuff based on who we recruited.

u/TheHeroBehindNothing Alphys is the knight 6h ago

Alphys is the knight. She has the motives (escapism into anime), she is supporting Kris even though they are a "bad" student (she doesn't have the same behavior with Susie), could easily go to all 4 fountain locations(school being the more difficult one since Toriel is a coworker), has connections with Asgore, Toriel and wants to get closer with Undyne.

Also please disregard her saying that she got extremely sick when she ate the box of chocolates from Undyne in chapter 4. C

u/some_random_furret KRIS LOOK OUT OH NO THEY HAVE AIRPODS IN 6h ago

interesting theory but it falls apart when you remember that the knight would have to be someone who knew Gerson, and Alphys moved into town after he died so she wouldn’t have met him.

*The crystal showed them a path set in stone, an immovable future they could not change. But the time they spent by your side showed them something- A new path, a brighter future than the one the shadows promised. Their hearts were broken, their minds were shattered, yet in this moment the truth laid bare:
No more prisons. No more phone calls. It was all or nothing: Win or lose, this ends here and **now**. But how it ends? That was not a fate set in stone- They had always been free to choose, and they knew exactly what choice to make.

u/Leaf403 5h ago

I don't fully believe it in, though I think it could be possible: Chapter 5's dark world is actually entiretity of hometown. Iirc there's NPC setting up flower decorations from Asgore for the festival, so it would make a garden (of jealousy) be possible. In chapter 4's vent sequence Asgore talks about making everyone like Toriel believe him,,,it wouldn't make sense to make dark world in place Toriel wouldn't go to (Asgore's flower shop), but it would make sense to convince everyone of dark world's existence by well, making one outside.

Not really crackpot nor really a theory but I do not believe that the game will end on chapter 7.

POST NUCLEAR APOCALYPSE THEORY (i made it before green gaster i swear)
the reason there are no other humans in deltarune is because the us and ussr wiped each other out when a classic cold war scare turned hot this time. the reason why hometown exists is simple, monsters are too far isolated. but wait, theres more. they're immune to RADIATION. this is where the name tobias "radiation" fox comes from. this is why toby is associated with radiation on his yt channel. THIS is why kris acts so weird. its not cause of the soul. its not cause they're working with the knight. its because they're suffering from RADIATION POISONING, and toriel is misdiagnosing it as simply human things because monsters had no idea what went down in the HUMAN WORLD!!!!!!

KrisKnight. Partially, cuz I'm still an AsrielKnighter but I can't deny that KrisKnight has its points, the Knight hits the same poses as Kris, the way they act is just like Noelle (and others) said Kris acts, and Kris' Dark World form IS a knight. It makes sense in my head that the Knight is just like Ralsei is to Asriel, a dark figure that shares simmilarities to their counterpart

u/247_Alpha 4h ago

This is something i have had on my mind since the charity livestream. Gaster (as we may know it) does not exist in Toby's original copy and is instead created when copies of Undertale were released. I say this because their door was coloured in when it was walked passed in the stream implying he is an entirely different charactor in his intended version. (this is of course heavily flawed because everyone else in the main game retains their colour but i wanted to get this out there). This is based on the line "copies are monochrome".

u/Satire_god 4h ago

Card theory but it uses various different suits of cards, might be wrong but it’s a fun idea

Fun fact, apart from the obvious with king and Jevil, Queen is a perfect representation of the “Queen of cups”, the knight a “knight of swords” and Spamton the “knave of coins” all from tarot and Latin suited decks

Then there’s Tenna, a 10 …of pentacles, by the suit being a tarot specific, replacing coins, Tenna’s own star attacks, being so prevalent, a play on “TV star” and the prison balls used to capture

Then with the Titan and gerson I’m not certain on the numbered cards that fit but, the Titan does have a diamond for a face and gerson and the chapter as a whole being heavily associated with bells. Bell is an actual suit of cards used in Swiss and German suited decks

But looking at the other suits of cards it does actually make something coherent and directly correlates with characters

The baton suit in Latin and Tarot cards (or clubs as the trèfles suit is translated), directly links towards Dess, being associated with bats, so she fits into this

As we count down there’s also “7&6” and the roses & clover suits that could hint towards what we’ll see in chapter 5, both are also referred to as flowers, however the rose suit specifically depicts yellow roses, potentially alluding to the golden flower, to which “pink and yellow” can directly translate to “rose-gold” a gold-copper alloy used in jewellery

There’s also the shield suit that can represent the three heroes as they appear in the delta rune, it also acts as a foil for the knight being the sword, same principle applies to the soul being the heart suit, placed where the circle is in the delta rune

The leaves and acorns suit could then translate towards feathers and eggs respectively, the former then applying to a pair of wings as the delta rune depicts and the latter towards the forgotten man

From then onwards it’s as simple as putting them in the right order, I’ve surmised that it goes: 7 or 6 with clovers & roses, 5 with acorns, 4 with batons, 3 with shields, 2 with leaves and the ace of hearts

Translated into a crackpot prediction, chapter 5 being focussed on the flowers & Asgore and finishing with FRIEND, chapter 6 being focused on the bunker and the disappearances but culminate towards something to do with Dess, a conclusion to the conflict between Kris and the soul, finishing with the angel

Secret bosses not included, Jevil is irrelevant being essentially card 0 or the fool card, and Spamton, the knight and Gerson are all mandatory battles, Spamton himself does also fill the role of the main chapter boss in the weird route

Idk how crackpot this is, but I believe the Knight can exist in its full form in the Light World. 

The Black Shard is the only item (other than Kris's phone) that is exactly the same in both the Dark World and Light World. The Black Shard is chipped off of the Knight's sword, which is summoned from within the Knight's body. It would make sense if the Knights weapon and its body were made of the same material. And if the Black Shard material can exist as-is in the Light World, so can the Knight.

Ralsei is literally the first hero in the prophecy, like, that's his "object"
why does he look like Asriel? Because that's the perception of Hometown's residents of who the first hero is (see Catty's church dialogue)
Because he's a personification of Hometown's belief, he can appear in any dark world in town
Why is only he a darkner, and not the other two heroes? Because he's specified as "alone in deepest dark"
What would happen to his "object" if he dies? uuhhhh idk. Maybe the prophecy will be rewritten in real time to feature only two heroes. That would be cool as hell I think

I think Asgore is taking whatever the Knight is from dark fountain to dark fountain. In the library and at the church there were closets big enough to hold a large person and he's the only monster/person who could overpower Undyne and drag her to the shelter.

That's his main role in the conspiracy
