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 dark grey eyeshadow. She also has a piercing on her right eyebrow. 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.
