Loona looks like a teenage wolf. She has a snout with pointed teeth and a dark gray nose, red sclera with white irises, white fur with gray spots on the shoulders, and voluminous gray hair combed to the side to reveal her ear.
Loona has an eyebrow piercing and a black choker with white spikes. Her gray crop top has star-shaped strings to look like a pentagram. She also wears fingerless gloves and shorts without shoes.
