Spamton and my theory as to who is the Roaring Knight
Now, like many, I have quite a few theories as to who the knight might be. I was once an advocate for Kris knight, then new chapters came out, and I was a believer in Dess knight. Then chapter 5 came out and Rudy knight became more compelling to me, but the truth is, they were never 100% fitting for me.
The reason for that is the fact that none of the candidates seemed to really fit either personality wise and in context. Here is what we know about the knight so far:
•They have a lightner's determination to open fountains
•They are a shapershifter covered in darkness
•They are quite smug based on their behavior
•They are powerful enough to overpower someone like Undyne
•They seem to be made of the same material as the shadow crystals (or at least their blade is)
•They are working alongside Kris and probably Carol for a goal in common
•They don't kill lightners, only darkners.
The last point in particular is one I don't see people bring up enough when it comes to the knight. For someone who is willing to possibly end the world (and we do know they know the prophecy seeing as they were in the church with panels about it all around) they seem surprisingly careful not to hurt lightners. Meanwhile, they seem to care very little for darkners.
I saw this theory that claimed that, based on their appearance, the knight might be a shadow, like the titan or the shadowmen we find in chapter three. Or at least something not tangible, something made from darkness.
Now, I have two main issues with this theory: How a darkner would have a lightner's determination and how dismissive they are of Undyne's kidnapping.
To solve this issue we (thankfully) don't have to look further than our favorite possessed doll, Spamton G. Spamton
See, what is interesting about Spamton in chapter two, is that he is the only darkner who seems interested in our SOUL. From the moment he merts us, he asks to see it and then, as NEO, he actually tries to steal it to reach HEAVEN. Now, what is HEAVEN for a darkner, particularly a cyberdarkner who only knows the internet? Could it be the light world? In other words, Spamton seems to believe that, by absorbing a lightner's soul, perhaps a human soul in particular, a darkner is able to maintain their darkner form in the light world.
This is fascinating when compared to Undertale, the previous game by Toby Fox, with quite a few connections with Deltarune, where the most powerful beings are born when a monster absorbs a human SOUL. In Undertale, magic seems to be strongly related to why this works, with monster magic being different from human magic. In Deltarune, however, magic doesn't exist. With the exception of the dark worlds. So maybe, in Deltarune, it requires a darkner coming together with a lightner to produce beings as powerful as the ones seen from a human and a monster SOUL together. A being as powerful as the Knight.
As to whose SOUL the Knight could have taken, I think there are only two legitimate candidates: Kris and Dess. I don't think they have Dess' SOUL because I am still of the belief she is lost somewhere in the Depths (hey, remember when it was heavily implied that Spamton is the only one capable of hearing her? And that may be the only time in the whole game where we actually hear her speaking? What was that about?). If Dess is still alive, she probably still have her soul, which leaves us with one candidate.
Now, for this theory to make sense, you need to be of the belief that we are not Kris' soul and while I don't think it has been exactly confirmed, it is heavily, HEAVILY implied to be the case for several reasons:
•A SOUL is supposed to be the very culmination of one's being. It is everything you are, your memories, your wishes, your hope. But we don't have any of that when it comes to Kris. We don't even seem to agree when it comes to making the roaring happen or not.
•Kris doesn't seem to get along with us at all. They seem to resent us, even in a pacifist run where you spare every enemy, they are incredibly antagonistic towards the player and are constantly trying to prevent us from ruining their plans, even if we don't really know what that may be. Shouldn't someone and their SOUL be in the same wavelength?
•We don't just control Kris. Throughout the chapters we take control of Susuie quite a few times as well, something we never did in Undertale for example. Now, it is true that our control over Susie is different than with Kris, but keep in mind, we are also not her actual SOUL. She has her own determination still. We are just an extra in her body.
•You could even argue we do this with Noelle and Ralsei during when we tell them what to do in battle.
•Kris is referred to as a 'cage' in chapter three, which is a weird way to refer to someone and their soul, isn't it?
So how did Kris lose their SOUL? Well, it has been mentioned several times throughout chapters now that Kris has done some sort of ritual in the past with Catti. A ritual where they were abandoned to finish alone. This is not some hidden thing either. The first time we learn about this is in chapter 2 when we get captured by Queen, meaning it is an almost impossible detail to miss, and then Catti will remind us almost every time we talk to her. That is all to says, whatever this ritual was, it was important.
A few other details to consider that link the knight and Kris:
•The similarities between Kris and the knight, including their poses.
•Their interest in using a sword, and the fact that Kris, upon getting into a dark world, is also turned into a knight.
•Their disdain towards most darkners (particularly Tenna)
•The ability to shapeshift itself, which is something quite rare in both Deltarune and Undertale. The only time we see shapeshifting in undertale are either with the ghosts by possessing something else, amalgamations and Asriel after absorbing souls
•I also think it makes a lot of narrative sense, considering that this is literally fighting Kris during their darkest time, right before the start of the game. A Kris that didn't have the friends they have now and are a lot less torn as to what should be done.
In conclusion, my roaring knight theory is that the roaring knight is a darkner made of shadows or something equally abstract who has absorbed Kris. What is this darkner? Well, pick your poison, really. Could be the song 'Don't Forget' as the video implies, it could be someone's actual shadow given form, maybe even Carol's, it could be a manifestation of the knight from the prophecy itself (assuming there is one) or Carol's belief's of what a knight should be. I think that my only thing is that it is likely a darkner related to the Holidays. What it is exactly, I don't think it matters as much, in particular, since it can change forms so easily. And all of that thanks to Spamton G. Spamton.
