The Rudy Fallen Angel (Devil/Lucifer) Theory | Rudy Knight
"Rudy can't be the Knight because he's nice and—" NO HE'S LITERALLY THE DEVIL.
Just look at Rudy's text box sprite. He has a goatee, a pencil mustache, a face shape, a hairstyle, eyebrows, a grin, eyes, and laughter — all just like the devil, and his antlers are... Christian crosses instead of horns? Well, this is very very interesting.
The Roaring Knight has these antlers with crosses too, but they're curved. It's like his antlers are turning into goat horns. Huh, goats. The symbol for Satan is a goat. If Rudy is the Knight, then his deformed antlers symbolize the fall. The fall of Lucifer. Rudy turns into a fallen angel in the Dark World, even though he's still innocent in the Light World. Or his motivation partially justifies him.
We also know that Dreemurr are goats. And who is their family's main friend? This is Rudy. Tenna's flashback, Fireshock spell and wedding photo point to it, Asgore's best friend is Rudy, Toriel communicates with Rudy, but doesn't like Carol and so on. He is the most goat-like reindeer among the Holiday family. Rudy even melted Carol's cold heart.
Let's go back to Lucifer. In Latin, Lucifer translates to "light-bringer" or "morning star". Light-bringer can refer Rudolph the Red-Nosed Reindeer on which Rudy is based. Rudolph's red nose glows/shines in the cold (Carol's and Noelle's symbol) and darkness (the Dark World) on Christmas Eve. The Knight can glow too. The Soul can shine too, using it against the Knight. If Rudy is the Knight, then it's ironic.
The hospital wallpaper has a sea (depths(darkness)), seahorses (dark horses-a chess horse-the Knight), starfishes (the Knight's bullets). btw stars glow and shine too.
Okay, there's also the devil's face on his sweater, a connection with Jevil, Friend and Gaster, plus the "Don't Forget" and "Raise Up Your Bat" lyrics and more. Just check the image or add something else in the comments.
And here is the most important question: Are these strong arguments for/a confirmation of the Rudy Knight theory? NO. Just a lot of interesting details before the release of Chapter 5. Some of them may be true if Rudy Knight turns out to be true. The rest will just be speculation.
Thanks to u/4Fourside for the idea of this theory! Before his comment, I was thinking about Rudy's appearance too, but the only thing that came to my mind was that he looked like Uncle Aaron from Spider-Man. btw, he's a very nice person in the Deltarune fandom.
