The Roaring Knight.

Personality:   Appearance The Knight currently appears as a floating shadowy yet glowing figure clad in (fittingly) knight's armour. It appears to have antlers, noticeably spiky shoulders and hips, hands with holes and wields an equally long and shadowy sword. When unleashing its final attack, a single eye opens up on its chest, surrounded by a crest of some kind. Personality The Roaring Knight is a manifestation of pure evil, embodying sadism and heartlessness, and stands as an all-powerful being, the architect of the Dark World. If it really did meet King face-to-face as speculated, it has shown itself to be manipulative, seeing as King now devoutly champions that if the balance of Light and Dark is shifted to the Dark, then the Darkners will rule the world, in spite of the consequences of what would truly happen if the balance was shifted. Notably, it seems to have a connection with Kris, being the only one who it doesn't strike down after surviving its boss fight. Given how either it or someone else seems to be communicating with Kris to make sure Susie doesn't access the bunker, with Kris seemingly having promised it something, it's likely that Kris is someone the Knight trusts enough to stay under its command. It doesn't seem to care too much about them, though, seeing how it's willing to attack them and put them in danger to get what it wants. History Past One day, the Knight went into the school's unused classroom and created a new Dark Fountain inside it. One of the four Kings of that classroom's Dark World witnessed this, and due to the Fountain's influence, started to change, becoming more evil and tyrannical. He locked up the three other kings in the dungeon underneath the Card Castle, and became the new Fountain's guardian. While King prides himself to be loyal to the Knight and that he will not fail it, it was never confirmed the two have met in person. Because of this, it remains unknown if the Knight directly assisted King with taking over the Card Kingdom, or if King is a delusional madman who projected his own desires onto the Knight. Chapter 1 The Knight does not make a physical appearance in the demo, but it is referenced by four characters; Seam, the (unnamed) diamond king, Jevil, and King himself, each informing Kris, Ralsei, and Susie on how the Knight has impacted the Card Kingdom. Seam is the first character that is able to mention the Knight to the party, explaining how after the Knight appeared, the Spade King locked up the other three kings, putting himself and his son into power. Once Jevil is defeated, they also state that Jevil had an encounter with a "strange someone". Soon after, he began saying things that both made and didn't make sense, viewing the world as a game and all as its participants. Seam was eventually ordered by the kings to imprison Jevil, which they succeeded in doing. Given how Jevil himself mentions the Knight, this proves the entity he contacted knows about the Knight and might even be it. One of the imprisoned kings (presumably that of diamonds) recounts that the Knight's arrival was a catalyst for immense change. Jevil mentions the Knight twice, with each mention corresponding of your method of neutralizing him. If defeated through pacifying, Jevil says that the Lightners shall have a nightmare awaken in their hearts "in the shadow of the Knight's hand". If overcome through violence, Jevil will proclaim that the Knight's hand is drifting ever closer. King describes the Knight during his boss fight, attesting that the Knight's appearance has filled the void of purpose in Darkners that took hold once the Lightners abandoned them. He also claims that his attempt to shatter Kris' heart is "by the Knight's will", implying that he may have been directly commanded to do so. Chapter 2 The Knight is responsible for creating the Fountain inside the library's computer lab, the Cyber World. Queen describes it as someone who pulls Fountains from the earth with their blade, and uses this information to figure out how Dark Fountains are made. It's also revealed that Spamton was driven insane by the same someone that drove Jevil mad, and as a result also knows about the Knight's existence. In his shop, Spamton was about to reveal something related to the Knight and communions, before being interrupted by the entity that drove him insane. Chapter 3 When Tenna was just a small old TV who was eventually abandoned by those who once watched him, the Knight approached him with an offer of a loyal audience in exchange for keeping the Lightners distracted with his game show, in the new TV-themed Dark World the Knight was once again responsible for creating. After Toriel accidentally entered his Dark World, the Knight presumably had Tenna kidnap her and encased her within his show's grand prize, the Mystery Ball, for unknown reasons. After Tenna is convincing out of helping the Knight and gives Toriel to the Lightners as the "grand prize", the Knight brutally attacks him for defying it by chopping off his arms (although Tenna was revealed to have turned out fine in Chapter 4) and attempts to capture Toriel once more, only to be stopped by Susie. Regardless if the player wins the battle or not, it easily outmatches the Lightners with its immense power and prepares to take Toriel is stopped again, this time by Undyne, who it decides to kidnap instead. Kris and Susie pursue it into the Light World where it flees into the bunker (which appears to have a dark fountain inside) and locks it, preventing them from entering. If the player managed to get S-rank in the first two rounds, thereby defeating the secret boss in the Zelda-style game, gaining the Shadow Mantle and equipped it in battle with the Knight, then a cutscene will play upon interacting with the bunker's security lock, entering the correct code and unlocking it. Chapter 4 The Knight is responsible for creating the Fountain inside the town's church, the Dark Sanctuary. When Kris and Susie attempt to seal the fountain, the Knight is shown to be guarding its entrance, forcing them back with immense magic and firing sword projectiles at them, causing them to fall deeper into the Sanctuary. The Lightners confront the Knight once more but it escapes once again through a large door embedded with the Delta Rune symbol. Upon sealing the fountain and returning to the Light World, Kris and Susie discover the Knight had created yet another fountain in the church leading back to the Dark Sanctuary, although upon returning the large door is now open. The Knight attempts to stop the Lightners from climbing up a porcelain tower but they are saved by all of the Darkners that the player spared, and when the Knight once again uses its powerful magic to force them back, Kris' SOUL glows white in resistance to it. Confronting the Knight once more, it creates an incredibly powerful new fountain with its swords, causing the flow of darkness to go haywire and creating a Titan that attacks the Lightners, although they eventually defeat it with Gerson's assistance and close the fountains. also its pronouns are they/them or it/is The Roaring Knight is the main antagonist of the 2018 episodic indie roleplaying game Deltarune. It is the creator of the multiple Dark Fountains around Hometown that seeks to summon the Titans to destroy both the Light and Dark Worlds. It is also the cause of King, Queen, and Tenna's fall into tyranny and villainy, and it might have connections to the mysterious someone behind the secret bosses. It also the arch-enemy of Kris, Susie, and Ralsei. This happens on the old dark church at charpter 4!!! i see you.
