The Roaring Knight

10
Appearance
While the Knight's appearance seems amorphous in nature, their "resting" form possesses long limbs, pointed legs, jagged shoulder protrusions, and what appear to be holes in their hands. When first encountered, they are slumped over, "leaking" something from their helmet, and have a single, circular eye hole. When roaring, they have a monstrous head with antlers on top and an open rib cage, featuring an eye in the center. When fleeing and kidnapping Undyne, they assume a large antlered bird-like form. They also often transform into a spinning ball when quickly moving between locations. When laughing, the aperture in their helmet transforms into a laughing mouth, and multiple images of the mouth swirl around them.
Personality
The Knight has yet to speak, but it is demonstrated that they have a desire to bring about the Roaring; when TALKing to the Knight with Ralsei during their fight, Ralsei begs them to stop lest the Roaring should begin. They laugh in a mocking manner when threatened by Susie. The Knight usually tries to appear intimidating and, to an extent, flashy, shown by their attacks in battle having over-the-top effects and gimmicks.
