The wait for Deltarune Chapter 3 has basically turned the entire fandom into a bunch of amateur detectives. We’ve all been staring at that final frame of Chapter 2—Kris ripping out their soul, opening a window, and stabbing the floor—thinking we’ve solved it. But Toby Fox doesn’t usually do "obvious." Honestly, the mystery of the Deltarune Chapter 3 Roaring Knight is way messier than most people realize.
If you’ve played Undertale, you know the drill. Expect the unexpected.
The Knight is the catalyst. They’re the one sticking a literal and metaphorical blade into the earth to create Dark Fountains. Queen calls them the "Roaring Knight," and they are the reason the world is on the brink of "The Roaring"—a literal apocalypse where the sky falls and Darkners turn to stone. It sounds heavy. It is heavy. But who is actually holding the knife?
The Kris Problem: Why the Chapter 2 Ending is a Massive Red Herring
Let's talk about the elephant in the room. Or rather, the teenager in the living room. At the end of Chapter 2, we see Kris create a Dark Fountain. It’s a shocker. Naturally, everyone jumped to the conclusion that Kris is the Deltarune Chapter 3 Roaring Knight.
It’s too simple.
Toby Fox loves to subvert expectations. If Kris were the Knight, why would Toby reveal it so early? We’re only two chapters into a seven-chapter game. Usually, you don't unmask the big bad in the second act unless there's a much bigger twist waiting in the wings.
Think about the timing. Queen describes the Knight as having a "long hand" and being able to create fountains. But the fountain in the library (Chapter 2) was opened while Kris and Susie were walking to the library from school. Unless Kris has some serious teleportation powers we haven't seen, they couldn't have been in two places at once.
Also, look at Kris’s physical state. When they rip out the SOUL (which is us, the player), they move like a zombie. They’re sluggish. They’re struggling. Does that look like a legendary knight capable of outrunning the police and magically infiltrating high-security areas? Maybe not. Kris might just be a "copycat." They saw how fountains are made and decided to open one in their own house—maybe to have another adventure, or maybe to keep Susie around longer.
Kris is likely a red herring. Or, at the very least, a reluctant participant in something much larger than a single person.

Papyrus, Gaster, and the "Missing" Candidates
Where is Papyrus? Seriously. Sans keeps teasing us about his "brother," but we haven't seen him yet. In Undertale, Papyrus was obsessed with joining the Royal Guard—becoming a knight. It’s a bit on the nose, right?
Some fans think the Deltarune Chapter 3 Roaring Knight is Papyrus because of his absence. It would be the ultimate Toby Fox move to take the most lovable, goofy character and turn him into a world-ending threat. But there’s a lack of evidence. We haven’t seen him interact with the Dark World at all.
Then there’s W.D. Gaster.
The man who speaks in hands. The guy behind the "Goner Maker" intro. While Gaster is clearly involved in the meta-narrative of Deltarune, he feels more like a puppet master than a knight. The Knight is someone who physically exists in the Light World. They have to. They need to be able to walk into a library or a closet and stab the ground. Gaster is "shattered across time and space." He’s a bit busy being a ghost in the machine.
The Alvin Theory: It’s Always the Quiet Ones
Have you talked to Father Alvin? He’s the son of Gerson, the legendary hero from Undertale. Gerson was a smith, a writer, and a hero. Alvin feels like he’s living in his father’s shadow.
There’s a weird drawing by Gerson’s grave. There’s Alvin’s dialogue about how he wishes he could be like his father. If you’re looking for a "Knight" who has a connection to the deep lore of the world and a reason to want to change reality, a grieving priest isn't a bad bet. It sounds crazy until you remember that Toby Fox hides lore in the most mundane places.
What "The Roaring" Actually Means for Chapter 3
We know Chapter 3 is going to take place in Kris’s house. The living room, specifically. This changes the stakes for the Deltarune Chapter 3 Roaring Knight mystery. If the Knight is someone we know, they might show up at the front door.
The Roaring isn't just a scary story. Legend says that if too many fountains open, the Titans will rise from the darkness and wreak havoc. The world will end in eternal night.

- Darkners will turn to statues.
- Lightners will be lost in the dark.
- The balance will be permanently broken.
The Knight is obsessed with this. Or, they think they’re doing something good. In many RPGs, the antagonist thinks they’re the hero. Maybe the Knight thinks the Dark World is "better" than the boring, stagnant Light World where Asriel is gone and Kris’s parents are divorced.
The "Discarded Vessel" Variable
Remember the character you made at the start of Chapter 1? The one the game told you was "discarded"?
"No one can choose who they are in this world."
That vessel is still out there in the game files. It looks like a grey version of Kris. If the Knight needs to be someone who looks like Kris but isn't Kris—someone who can move between worlds and has no "soul" of their own—the discarded vessel is the perfect candidate. It would explain why the characters in the Dark World don't seem to recognize the Knight clearly. They just see a "human" or a "figure."
If the vessel is the Deltarune Chapter 3 Roaring Knight, it sets up a perfect thematic mirror. We are controlling Kris’s body with a soul that doesn’t belong there. The Knight could be a body that should have had our soul, acting out in the world without any guidance.
What to Watch for When Chapter 3 Finally Drops
We’re all waiting for that release date. Until then, keep an eye on the details. Toby Fox has been releasing "Status Updates" and "Sams" (seasonal newsletters) that give us tiny glimpses of Chapter 3.
- The TV Man (Mike/Tenna): We saw the TV screen smile at the end of Chapter 2. While many think the TV is the Knight, it’s more likely that the TV is just the "Main Boss" of the Chapter 3 Dark World, similar to King or Queen. The Knight usually opens the fountain and leaves.
- The Person in the Bunker: There’s a bunker at the bottom of the town. It plays a slowed-down version of Gaster’s theme. Whoever is in there is definitely important to the Knight’s identity.
- The "Egg" Man: In both chapters, there is a hidden room with a man behind a tree who gives you an egg. Is this the Knight? Or just a cameo?
Honestly, the most likely scenario is that the Knight is a character we haven't officially met yet, or someone hiding in plain sight. Someone like the Mayor (Noelle's mom) has the authority, but does she have the motive? Probably not.

The mystery is the point. Deltarune is a game about choice—or the lack of it. The Knight is the one forcing choices upon us.
Practical Steps for Solving the Mystery
If you want to dive deeper into the hunt for the Deltarune Chapter 3 Roaring Knight, don't just watch YouTube theories. Do the legwork.
- Replay Chapter 1 and 2 with a "Knight" lens: Look at the dialogue of the Darkners. Notice how they describe the Knight’s arrival. King talks about them with reverence. Queen talks about them as a force of nature.
- Check the Room Layouts: The Fountain in Chapter 2 was opened in the library's computer lab. Look at who had access to that room. Kris and Susie were in school. Noelle and Berdly were already there.
- Analyze the "Claw" Dialogue: In the game's code and certain flavor text, there are mentions of "claws" or "sharp hands." This might rule out characters with soft features.
The most important thing is to stay skeptical of "obvious" answers. Kris holding a knife is a classic cliffhanger, but it’s rarely the whole story. We’ve still got five chapters to go. Toby Fox is just getting started, and the Roaring is still a long way off.
Keep your save files ready. Whether the Knight is a discarded vessel, a skeleton in a hoodie, or a grieving priest, we’re going to need every bit of HP to face them. Focus on the subtle clues in the town’s NPC dialogue—that's usually where the real lore is buried. Noelle's father, the history of the town, and the strange disappearance of Dess Holiday are all connected to why this "Knight" started stabbing the earth in the first place. Stop looking for a villain and start looking for a motive. That’s how you’ll find the Knight.
