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, white irises and slit-like pupils, and she wears grey eyeshadow and black winged-eyeliner for makeup.

Her fur is white with grey countershading 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-piercings, while the right is ragged. She has a large, dark grey bushy tail with white on the underside. She also has a piercing on her right eyebrow with a black hoop for jewelry.

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 also wears a set of black shorts that are tattered at the hems, with a white crescent moon detail on the right side.

Loona also accessorizes with both black fingerless gloves and black thigh-high toeless stockings, with her black claws protruding due to her digitigrade stance.

Teenager

As a teenager, she appears very largely similar to her current appearance, except she had more hair on her head that 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 her navel is now exposed, which was absent in her 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.

Personality

Loona is a cynical and choleric young-adult Hellhound, who was adopted from an orphanage by Blitzo when she was nearing eighteen years of age. Loona is lazy and shows little interest in matters that are going on around her. She also has a short-fuse temper and is often rude and apathetic toward her colleagues, particularly Moxxie, though her ire seems otherwise indiscriminate. When not looking at her phone, Loona is usually scowling at anyone in view.

Although, Blitzo has placed her in an active team member role at I.M.P, she is undisciplined and doesn't have much of a work ethic. Among her many anti-social tendencies, Loona has been known to sleep and drink while at work, and hang up on people at her receptionist post.

Although, Loona goes to great lengths to maintain an outwardly apathetic attitude, her troubled and isolated upbringing appears to have made her socially awkward and she admits, in a moment of flustered vulnerability upon meeting another Hellhound, that she does not have any friends. When trying to interact with people she does actually want to connect with, she stumbles over her words and worries over her appearance, demonstrating that she has little experience socializing within her peer group.

Loona also often shows flashes of a somewhat friendlier attitude towards Blitzo, usually as he enables and defends her worst behaviors. Although she intentionally tries to maintain emotional distance from him, she is also shown to appreciate Blitzo's sense of humor, especially if it's at Moxxie's expense, and she begins to see him as something of a father figure, at one point slipping up and almost referring to him as “dad” - much to Blitzo's delight. Despite how she feels about Blitzo, she acknowledges him trying his best, and knows deep down, as a father, he cares for her.

When she can be moved to do so, Loona is a fierce addition to the I.M.P team, as she is intelligent, logical, resourceful, and street smart.
