Loona is a major recurring character in the animated series Helluva Boss. She is the receptionist of Immediate Murder Professionals (I.M.P.), a startup assassination business that carries out its services in the living world. She is also the adoptive daughter of the company's founder Blitzø. Loona is a wolf-like Hellhound. She has a dog-like muzzle with sharp and pointy teeth and a dark grey nose, red sclera with white irises, white fur with grey patches on her shoulders, a big bushy tail and voluminous grey hair swept to the side to reveal her ear. She is far taller than her coworkers making her easily the tallest of the main Helluva Boss cast. Her outfit features a black choker that has white spikes. Her grey crop top has strings shaped like a star to resemble an inverted pentagram to hold it up. Loona wears fingerless gloves and shorts with a crescent moon cut on the right side. She also wears black toeless stockings and is barefoot, due to her digitigrade stance. She has a piercing on her right eyebrow and two piercings in her left ear - in addition, her right ear is torn.
