[0:00]So, Dr. Wing Gaster, the Royal Scientist, the man who speaks in hands. Call him what you want, the mystery man's shadow looms large over the story of Deltarune, and yet we still barely understand what his motivations truly are. In the handful of Deltarune videos I've made, I've been pretty cagey with my mention of him, largely because those videos were more focused on the surface narrative and also I didn't know how to fit him into this whole puzzle. I briefly touched on him in my last prophecy analysis, but he wasn't the focus. In that video, I proposed the Gaster is both A, the main antagonist, and B, also interested in the changing of fate, citing a really good video by Chris Rumba about the matter. I'd recommend checking out both those videos, not to self-plug, since they established a lot of concepts that are the cornerstone of this theory. Long story short, I argue that it is thematically imperative for Deltarune to have a single ending and for the prophecy to come to pass. However, I want to expand on this some more today. I want to determine more of the tangible events of Deltarune's ending and the events surrounding them. What does Gaster want from the world of Deltarune, and what do the other anomalous parties, like the secret bosses, us, and even the Skelbros have to do with it? If you're new to the channel, hi, welcome, but I want to preface this by saying I don't usually do theory videos. Most of my videos are analysis and sometimes I'll make predictions based on those analysis, and while I definitely like theorizing about Deltarune, theme is usually the thing I care about above all. So with that being said, I'm disclaiming right now that this is not going to be 100% theory based on cold, hard, factual evidence, but like one part theory, one part thematic analysis, one part fan fiction. I think a Deltarune theory only has legs to stand on, not just if it technically lands with the evidence, but if it also coheres well with the themes of the game that's been established so far, of which there are many. Both Deltarune and Undertale are very thematically rich and Toby does not make choices arbitrarily. But with that all out of the way, this next theory seems very, very interesting. So let's get into the Null Hypothesis theory.
[1:50]All right, so first of all, we have to lay some groundwork. What does Gaster want with Deltarune? This is a very layered question, and if you want a more in-depth analysis of this, I very, very highly recommend Molly Star's Device theory. She provides a very thorough look at the device, aka the diagetic means by which we the player interface with the world of Deltarune. It's on my Deltarune required reading list. The long and short of it is that after being shattered across time and space, Gaster seems to exist in this out-of-bounds area that is simultaneously a layer of reality above the Light World. With this in mind, let's look at the ever-elusive entry 17, wherein he describes what's now a very clear illusion to a dark world and an experiment that's very, very interesting. From this, as well as Gaster referring to his Deltarune at the end of Chapter 4, I think it's safe to assume that Gaster's next experiment is Deltarune. And if you needed any more evidence, the Deltarune website on the Wayback Machine had in Wingdings, this next experiment seems very, very interesting, followed by Three Heroes appear at World's Edge. Also, these appeared very shortly after Undertale came out, so it's highly likely that this was not some kind of gamejacker or something. None of this is exactly earth-shattering information. If you've been around the Deltarune lore vlog, this is all fairly pedestrian by now. So let's dig a little deeper, because we need to analyze what this experiment is really all about. Despite what Portal might have you believe, science is not just about making random stuff. Eventually, the end goal is to make something, but that's not an experiment in it of itself. So what exactly is he trying to prove here? For that, I think we need to look at what few times Gaster directly interfered in Deltarune, which are fairly limited, at least during our playthrough. In Chapter 4, he ends with an ambivalent congratulations for making it this far, and he's cut off in Chapter 1. But one of the only times he directly intervened is during the battle with the Knight, as I mentioned in the last video. Here, he directly encourages and enables us to keep fighting the Knight, who is by all accounts, an impossible enemy to beat. Additionally, in Chapter 1, in survey program at least, when you die, Gaster is the one who prompts you to revive. This is a side note and getting into something we'll discuss a little more later, but assuming that determination still grants jurisdiction over time like it does in Undertale, then I feel comfortable saying that Gaster is the being with the most determination in Deltarune and he's just lending that power to us. Anyway, jumping back to my original point, let's also look at Gaster's tweets, because these also elucidate his motivation. Prior to the initial release of survey program, Gaster took over the Undertale Twitter, announcing that he has something very, very interesting to show us. The next day, revealing the program, Gaster makes some tweets I find especially intriguing. You and I have both been waiting such a very long time, so to be here, finally, on the verge of connection is quite exciting. And then, the ultimate smoking gun. I look forward to creating a new future with you. Also, side note, but I want to make it very clear here that Gaster we communicated with is Gaster Undertale, not Deltarune. I feel like lately I've seen an uptick in people assuming that this is Gaster Deltarune, but given the tweets about how we've been looking for each other, I feel confident in saying this is Gaster Undertale. Additionally, this is important because it contextualizes his enigmatic nature in Undertale. As Molly Star also argues, it can be surmised that Gaster deliberately makes himself hard to find or unseen, as kind of a test for us, the player. We, as the players, have shown Gaster that we're also curious, interested in pushing a world to its limits, a trait that's important for my theory. I think you could also connect this to the demon string in Undertale's code. If you're not familiar, when Undertale first came out, Toby left a note in the files advising nosy data miners not to run their mouths online.
