Take Spamton NEO for example, the reason why a boss based off of Mettaton Neo even exists at all is because it was Toby Fox's goal to make a real Mettaton Neo bossfight for Deltarune. It's literally a lost dream manifesting from player's hopes of a full Mettaton NEO fight, manifesting itself into the Spamton Neo fight.

Similarly could be said for the other main Undertale reference bosses, the Hammer of Justice and Pink. Both wheren't fully explored in Undertale, but they're dived into a bit deeper here. I'd say Jevil is possibly the dreams of DELTARUNE from 2012 finally coming to fruition, as we know he's existed for a LONG time.

So, with that in mind, what do we suppose the Pure Crystal might do? If shadow crystals allow us to peer into an alternate timeline, then assuming that a pure crystal is much more powerful, perhaps it could allow Kris to not only see alternate events but actually reach into them in some way... either to pull something through into their own timeline... or perhaps, to push something else into that alternate timeline. As for what that something could be... I have my guesses, but I'm not quite ready to divulge just yet, haha.

hey so. Guys. We have been willingly giving a singular shopkeep broken dreams which are an inexplicable power in the Dark World right? For five chapters. To a character WHO USED TO BE FRIENDS WITH JEVIL AND IS AS WELL KNOWN OF A TRICKSTER. And it's not like they have done anything to dissuade that (other than being a cozy and friendly face).

plus me doing some rotate-y stuff for Reasons

Ok so.

You know how we all kinda collectively agree that Shadow Crystals drive people (or at the very least darkners) crazy, right.

And how the crystals like… show you things when you look through them, yeah? Things which may or may not be true.

And you know how the Knight’s armor is like. Made entirely out of both Shadow Crystals and Black shards, right.

And how the knight kinda acts a bit… Off? At times? Like it isn’t *entirely* there?

SO. I realized a few things:

1. Um. The knight is basically constantly looking through its armor which is made entirely out of shadow crystals. things which alter your perception even in the light world. MAYBE that might be affecting its behavior. Idk. Maybe being covered in crystals containing *someone else’s* will & desire might not be good, actually?

2. I ALSO remembered that a major inspiration for Undertale is Moon: Remix RPG Adventure. And in Moon, there’s a character called Hero who is actually a different character who went missing and is trapped inside a cursed set of armor (He was put in there by the minister that works for ‘King Carefree’) that distorts their perception of reality. To the Hero, they are a holy warrior, viewing everything as a game with them as the valiant hero. Yet to everyone else, they’re just completely delusional and needlessly violent. By the end of the game they deal 9999 damage to everything, capable of instantly killing anything they come across, near the end of the game they’re even able to repeatedly deal 9999 damage to the dragon. (Killing the dragon in-universe ends the game btw. The dragon’s death and the game ending are also prophesied in tablets and is implied to be inevitable.)

3. I also ALSO remembered that in Mother 3, (Spoilers for Mother 3 btw) the masked man is a character who was lost (presumed to be dead) but was revived/turned into a human chimera by Dr. Andonuts under the orders of Porky Minch (Aka, King P), so that Porky can use the Masked Man to pull the 7 needles (which I’m not the first to bring this up but pulling the needles really feels similar to how creating a fountain is portrayed but like… in reverse) so that the future he wants (an apocalypse which will destroy the universe) will come to pass. Mother 3 also has a dragon (The Dark Dragon) which ends(?) the game/world when it wakes up.

This apocalypse is also kinda implied to be ‘inevitable.’ since the magifolk (I’m not calling them by the fan-translation name.) kinda imply that this needles have to be pulled *eventually* and that whether the end is good or bad will depend on if the intentions of the person pulling the needles is good or bad.

The reason why i bring up both Mother 3 and Moon is because... well…

An inevitable apocalypse. A dragon that ushers in the apocalypse. A masked, brainwashed, supposedly-dead individual who’s related to another character & is ultimately working towards causing the apocalypse. This individual’s ‘revival/brainwashing’ is ultimately caused by a person who works under a king. Hm. I wonder what implications that might have for deltarune. I really wonder.

Hell, the starting town in Moon is called Castle Town, and the town in Mother 3 is called Tazmily Village (with the soundtrack notably referring to it as “Mom’s Hometown”)

Uh… Fuck, this is kinda all over the place i kinda started rambling too much about Moon and Mother 3.

Uhh…

TL;DR:

0. This theory kinda only works if you subscribe to Dess Knight being true.

1. I think the knight’s armor being made of shadow crystals, crystals which contain the will of *something or someone* and distort reality when looking through them, might be affecting its behavior.

2. I very strongly feel that the knight is inspired by both the Hero from Moon, and the Masked Man from Mother 3, both games which we KNOW Toby really likes. (I also think the knight is inspired by The Batter, but i have less evidence for that other than the fact that the batter also causes his game’s universe to end at the end of the game and that being his ultimate objective. Also just the general baseball theming surrounding Dess.)

3. Because both the Hero & the Masked Man were “created” by a person serving directly under a King, I feel like Gaster is directly involved in whatever happened to Dess that turned her into that. It also very neatly resolves the issue of why Gaster and the Knight have overlapping theming/narrative imagery in certain areas.

4. Because both the Hero & the Masked Man are “brainwashed” I feel like the Knight’s armor is also forcibly imbuing the will of the shadow crystals into the knight. With the caveat that the Knight is not completely mindless, but only partially piloting its own body. Hell, it might not even be that the Knight is ‘brainwashed’ and more like both parties are mutually using each-other. Kinda like how we control Kris, yet Kris also is using us for their own goals. (Also neatly works with how the Knight parallels Kris) (Side note: If the will that’s partially controlling/working with the knight is Gaster, that would kinda explain why the only instances of gaster talking to us are when the knight is directly in front of us (the Knight Fight) or when the knight is talking to Kris (End of Chapter 4)) (oooh but what if the knight was like… dess’s soul is actually in the vessel we made at the beginning of the game and the ‘armor’ isn’t even armor its just the condensed form of dess’s will leaking out and taking on a form vaguely resembling dess’s prior body. and bc the vessel was made by us and gaster it contains both our and gaster’s wills as well. Folks this is how oblivion theory can still win.)

5. Really want to emphasize that the whole “The knight being imbued with the shadow crystal’s will being why its so off-kilter mentally speaking.” thing is more-so like… a symbiote kind of deal? rather than a full on mind-control thing. or like. ok this is stupid but its like. Imagine that the will in the crystals is like a videogame HUD saying “Go here.” or “Do this.” or giving flavor text or something. Or like. Someone being possessed. Where they’re still like. Cognizant? But their mind is definitely still being influenced and how much of ‘them’ is still there can fluctuate depending on the scenario. Like being straight up-injected with the emotions, desires, and perspective of another person. It’s like that. It’s like narrachara or asriel’s whole deal after exiting the barrier but if chara was gaster instead and asriel was dess. Like they have to actively work in tandem or something or else their body wont actually work. 2 kids in a trenchcoat type shit. Am I making any sense or is this nonsense.
