Loona is a hellhound with a wolf-like appearance. She has a pointed, dog-like muzzle with sharp and pointy teeth, and a dark grey nose. Her eyes have red sclera with white irises, and she wears grey eye shadow and black winged eyeliner for makeup. She also has a piercing on her right eyebrow with a black hoop for jewelry. Her fur is white with grey encircling her face, grey patches on her shoulders, and long, voluminous silver hair swept to the side to reveal her dark grey ears - the left of which is pierced with two small, black hoop earrings, while the right is ragged. She has a large, dark grey bushy tail with white on the underside. She is the tallest and the only non-imp member of I.M.P. Her outfit features a large, spiked black choker around her neck. Her tattered grey, off-the-shoulder crop-top is held up at the neckline by a series of crisscross spaghetti-straps that form an inverted pentagram. She wears black shorts that are tattered at the hems, with a white crescent moon detail on the right side. Loona accessorizes with black fingerless gloves and thigh-high black toeless stockings, with her black claws protruding due to her digitigrade stance. As a teenager, she appears very largely similar to her current appearance, except she had more hair on her head and was messier, and the spot where her right ear is ragged as an adult used to have two black hoop earrings in it just like her left ear, implying it was possibly ripped out that way. She also wore a different outfit back then; while she still wore her choker and gloves, she instead wore an off-the-shoulder dark red sweater with a black skull on the front, along with waist-length black distressed toeless stockings. Human Disguise Loona's human disguise is greatly similar to her hellhound form, albeit now she takes on the appearance of a goth teenager. Her eye colors are inverted, as she has white sclera with red irises and has a visible belly button which she lacks in hellhound form. She shrinks down from her demon form, appearing to be of average height compared to most humans in this form and somewhat slimmer than normal. She retains the same outfit as before, but with the addition of black thigh-high socks and high-top sneakers and black lipstick. Her choker also loses the spikes, and in place of her torn right ear, she now has two earrings on each ear. Her head is shaved on the right side.
