"Oh, what does it matter?! You’re not my real dad, I was almost eighteen! I didn’t need you then, asshole! I don’t now..."
―Loona to Blitzo, for smothering her

Loona is the receptionist of I.M.P, the adoptive daughter of Blitzo, and one of the main protagonists of Helluva Boss.


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 co-workers 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 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.

Human Form

Loona's humanoid form is largely identical to her hellhound form, albeit human. Her eye colors are inverted, as she has white sclera with red irises. She shrinks down from her demon form, appearing to be of average height compared to most humans in this form. She retains the same outfit as before, but with the addition of black knee-high socks and high-top sneakers. Her choker also loses the spikes, and in place of her torn right ear, her ear piercings have now swapped to her right ear. Her head is shaved on the right side.


Cynical and choleric, Loona generally has no interest in matters that are going on around her. She is rude and apathetic toward her colleagues, particularly Moxxie, though her ire seems otherwise indiscriminate. When not looking at her phone, Loona is giving a hateful glare to anyone in view.

She is incredibly undisciplined and doesn't have much of a work ethic. Among her known behavioral issue, Loona has been known to drink to the point of a hangover before work and having unprotected sex to the point of contracting syphilis. She is also very apathetic to the suffering of others, as seen on the occasion where Millie called into the office for help after being stabbed only to be hung up on by Loona. Additionally, she was also shown taking pictures with her phone of the deceased Eddie when he was being beaten by Blitzo, Millie, and Moxxie. In spite of this, she is shown to have a minimal amount of responsibility as she makes sure to keep the Grimoire safe from a fire in I.M.P's office.

Loona also displays an extremely short temper combined with emotional instability. Upon being questioned about something as simple as why she was eating Moxxie's lunch, Loona sprinted out of the office and assaulted an innocent bystander to vent her frustrations. This is particularly egregious, given the bystander in question was a baby in a carriage which Loona punted out of sight.

Despite this, Loona shows a somewhat friendlier attitude towards Blitzo, as he enables her actions, and at times when he defends her, she smiles and agrees to his defense. She is also shown to appreciate Blitzo's sense of humor, especially if it's at Moxxie's expense since she was seen stifling a laugh when the former made a joke of the latter's dick size. She also appears to see him as a father figure at one point slipping up and calling him dad much to Blitzo's delight. Another moment showing their relationship is when Blitzo tries to get between her and Vortex and she snaps at him. She seems to realize that she may have gone too far almost instantly and tries to apologize a few seconds later, though Blitzo storms off.

Her usual attitude appears to have also made Loona very socially awkward. During her interactions with Vortex she stumbles and struggles to speak a lot, showing she has little experience in these matters. She even at one point admits to Vortex she has no friends indicating that Blitzo is likely the only one she is close to.


Natural Abilities

  • Human Shapeshifting: Loona can take on a convincing human appearance to disguise herself in the living world.


  • Weapon Mastery - Loona has been shown to be proficient in the use of both firearms and melee weapons, as seen when Millie and Loona were attacking D.H.O.R.K.S.' staff and in I.M.P.'s standoff in the headquarters.
  • Combat Skills - As a hellhound, Loona boasts the agility and instincts of a wolf. She can rip an opponent open with her paws or her teeth, and she has the jaw strength to sever an opponent's head on impact. In both her human disguise and hellhound form, she also uses a variety of kicks.

Unique Abilities

  • Superhuman smell: Loona can detect and identify specific individuals by scent, which appears as a red aura around their bodies. She can also track down targets by smelling names on a list, as she demonstrated in "Spring Broken".



  • Loona's name is a reference to "Luna", the word for "Moon" in Latin and most Roman languages. The moon symbol on her shorts also support this.
    • It is possible that she was named and designed after the moon itself, since they both share a somewhat similar color scheme.
    • This is further supported by the fact that her Voxtagram handle, @moonlight_howling_666, has the word "moon" in it.
  • In the episode, "Spring Broken", she verbally reveals that Blitzo adopted her when she was "almost 18."
  • In "Truth Seekers", Millie claims she is older than Loona by five years.
  • The crescent moon on her shorts often changes between being a cut or a print, depending on her appearances in episodes.
  • Blitzo has a selfie taken with her during her adoption process in his phone's gallery. Additionally, the same adoption papers are framed just outside of Loona's room in Blitzo's apartment.
