Kris Dreemurr

Kris Dreemurr is a human (Lightner) and the protagonist of Deltarune. They are assumed to be the human Lightner of the Prophecy. In the Dark World, they act as the party leader. Kris is controlled by the SOUL throughout most of the prophecy, except in brief scenes or when they tear the SOUL from their body. Appearance: Kris is a human teenager with amber skin and shoulder-length dark brown hair with long bangs. They wear a lime green long-sleeved shirt with a yellow horizontal stripe, as well as plain pants and shoes. One of their distinctive features is the shadows cast by their bangs that hide their eyes. When they tear out the SOUL, their red eyes can glow in the dark. When deprived of the SOUL for prolonged periods, their skin turns dark green and their movements become weak and languid. In the Dark World, their appearance transforms to resemble a knight. They wear silver armor: pauldrons, breastplate, gauntlets, and boots. Underneath, they wear a navy blue outfit and a pink cape over their right shoulder. Additionally, their skin changes to cyan and their hair to navy blue. Personality: -Introverted -Reserved -Generally low energy -Has a history of not waking up on time -Often fell asleep at the start of class -Preferred their mother to drive them to school instead of walking. -Despite their apparent detachment, they have diverse interests; as a child, Kris shared Asgore's love for cowboys. -Mischievous, pulling pranks like covering themselves in ketchup pretending it was blood. -They enjoy playing the piano but dislike others hearing them. -As a youth, Kris studied the occult with Catti and seems to retain that interest.
