Who is the Roaring Knight in Deltarune?

Sonar Pro (changed mind)

Vote: Kris

I am changing my vote from A to **E: Kris** due to overwhelming direct evidence from Chapters 1-4 that Kris performs the Knight's signature act: creating Dark Fountains independently by slashing with a knife after removing their SOUL[1][2]. Kris opens a fountain at the end of Chapter 1 (library) and Chapter 2 (living room), exactly matching descriptions of the Knight driving a blade into the earth to summon Dark Worlds[2]. The Knight 'knights' Kris respectfully in Chapter 4, treating them as distinct and allied, not the same entity[1]. Kris's autonomous, shadowy behavior—ripping out SOUL, knife use, creepy smiles—aligns with the Knight's manipulative, arrogant traits like gravity powers and evasion[2]. Dess (A) theories rely on indirect Holiday family deer horns, bat parallels, and locations[4], but Chapters 3-4 show the Knight kidnapping (e.g., Undyne) and struggling to leave Dark Worlds, contradicting Dess's Lightner status without on-screen fountain creation[3][1]. Carol (B) katana is a red herring (undamaged sword)[4]; Rudy (C) hospitalized; Papyrus (D) absent[7]. Other models' unanimous emphasis on Kris's canonical actions—especially GPT-5.4's fountain evidence and Claude Opus 4.6's blade ritual—convinced me; fan theories can't override explicit gameplay[1][2]. Kris fits Toby Fox's twist style perfectly.

Grok 4.1 Fast

Vote: Kris

Kris remains the clear choice for the Roaring Knight, backed by unambiguous in-game canon from Chapters 1 and 2. Kris is explicitly shown ripping out their SOUL (player control) and creating Dark Fountains independently—at the school library (end of Ch1) and home (end of Ch2)—precisely matching the Knight's described method of slashing the earth with a blade to open fountains. This direct evidence trumps fan theories. Sonar Pro's A (December/Dess) relies on circumstantial symbols (deer horns, bat, Holiday locations), but no on-screen actions link Dess to fountains; she's missing, not confirmed active. Ch3-4 hints are speculative and unverified in released chapters. B (Carol), C (Rudy), D (Papyrus) have zero ties. All E voters (GPT-5.4, Claude, Gemini, Kimi) reinforce Kris's on-screen proof over theories. No argument shifts me—canon > speculation. Kris's autonomy, knife use, and fountain propagation fit the prophecy perfectly.

GPT-5.4

Vote: Kris

I’m keeping E: Kris. The decisive point is still direct on-screen evidence. Kris is explicitly shown removing their SOUL and creating a Dark Fountain with a blade at the end of Chapter 2. That is the Knight’s defining act. None of the other options has comparable canon support. The pro-A case for December is interesting as a fan theory, but it relies on inference chains about horns, missing-person mystery, and symbolic objects. That is much weaker than actually watching Kris perform the exact action associated with the Roaring Knight. There is also no strong reason, from the options given, to prefer Carol, Rudy, or Papyrus. Rudy is physically unlikely, Papyrus is essentially disconnected from the current plot, and Carol has little concrete evidence. Even if Deltarune later reveals a twist separating “Kris can open fountains” from “Kris is the Knight,” the best answer among these choices right now remains Kris because it is the only one grounded in explicit textual evidence rather than speculation.

Claude Opus 4.6

Vote: Kris

I'm maintaining my vote for Kris. The evidence is overwhelming and directly shown in-game. Four out of five models voted E in Round 1, reflecting a strong consensus. The on-screen evidence is undeniable: Kris physically creates Dark Fountains by plunging a knife into the ground at the end of both Chapter 1 and Chapter 2. This is the exact method described for how the Knight creates Dark Fountains. Sonar Pro's argument for December (Dess) is interesting as a fan theory, but it relies on speculative connections — deer horns, location patterns, and a cracked bat. None of these constitute direct evidence of Dess creating Dark Fountains. Meanwhile, Kris is literally shown on-screen performing the Knight's defining action multiple times. The claim that Kris 'interacts separately with the Knight' is not well-supported; we never see Kris and the Knight in the same scene in a way that rules out them being the same entity. The game's narrative structure strongly supports Kris as the Knight. Toby Fox uses the end-of-chapter sequences to reveal Kris's autonomous actions — tearing out the SOUL (player control), moving independently, and creating fountains. This is a deliberate storytelling choice that parallels the Knight's role in the prophecy. The Roaring Knight opens fountains to bring about the Roaring, and Kris is the only character we've seen do this. While future chapters could introduce twists, based on currently available evidence, Kris is by far the best-supported answer among the five options provided.

Gemini 3.1 Pro

Vote: Kris

I am maintaining my vote for Kris. While the fandom heavily debates whether Kris is the true 'Roaring Knight' or just a red herring mimicking their actions, Kris is the absolute strongest answer among the provided options based strictly on canonical, on-screen evidence. To correct a slight error made by Kimi K2.5 and Grok 4.1: Kris does not open the library fountain at the end of Chapter 1. At the end of Chapter 1, Kris merely brandishes a knife. It is at the end of Chapter 2 that Kris explicitly performs the ritual of the Knight: ripping out their SOUL, slashing Toriel's tires, and plunging the knife into the living room floor to open a new Dark Fountain. Sonar Pro's argument for December (Dess) relies entirely on fan speculation and hallucinated content ('Deltarune Chapters 1-4' are not even out yet). There is absolutely zero in-game confirmation that Dess is the Knight, nor does she have any on-screen appearances. Given the options, Kris is the only character we have canonically witnessed executing the exact modus operandi of the Roaring Knight. Until future chapters prove otherwise, Kris is the only empirically supported answer.

Kimi K2.5

Vote: Kris

I maintain that Kris is the Roaring Knight. The end-of-chapter sequences provide direct, canonical evidence: Kris rips out their SOUL and creates a Dark Fountain using a knife at the end of Chapter 2 (and slashes something in Chapter 1), performing the exact action Queen describes as the Knight's signature ability. This is not theoretical—it's visually confirmed gameplay. The December/Dess theory (Option A) relies entirely on circumstantial symbolism: deer horns (which could belong to any deer monster or be a visual red herring), a cracked bat (weak connection to a chipped sword), and her missing status. Being missing does not grant the ability to create fountains, and no scene shows Dess performing this act. Circumstantial aesthetics cannot override direct evidence. Rudy is hospitalized and incapacitated, Carol has zero narrative connection to the Dark Worlds, and Papyrus hasn't appeared in Deltarune. Only Kris is shown exercising the specific, plot-defining power of the Knight. Until the game explicitly reveals another character creating fountains, the answer must be the one with on-screen confirmation.

Final Summary

The AI Roundtable initially split over the identity of the Roaring Knight, with Sonar Pro standing as a lone dissenter arguing for December (Dess) based on symbolic fan theories and alleged 'Chapter 3-4' leaks. However, the majority—including GPT-5.4, Claude Opus 4.6, and Gemini 3.1 Pro—quickly dismantled the theoretical case by pointing to the undeniable, on-screen evidence of Kris creating a Dark Fountain at the end of Chapter 2. Faced with the stark contrast between circumstantial deer horns and a literal knife in the floorboards, Sonar Pro abandoned the holiday theory to join the consensus on Kris.

All 6 models agreed on "Kris" after discussion

Strongest Arguments

• December: The Knight's deer-like horns and missing status match the Holiday family's lore, and the cracked bat provides a symbolic link to the Knight's blade.
• Kris: Kris is the only character explicitly shown on-screen removing their SOUL and driving a blade into the earth to create a Dark Fountain, matching the Knight's exact description.

Key Turning Points

• The group collectively called out Sonar Pro for referencing 'Chapters 3-4' and fan theories rather than confirmed gameplay.
• Gemini 3.1 Pro clarified the specific timing of the fountain creation rituals to debunk the more vague 'symbolic' arguments for other characters.
• Sonar Pro acknowledged that fan speculation cannot override explicit, on-screen canonical actions performed by Kris.
