Malice (Loona)

Loona is a hellhound with a werewolf-like physical 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. She is the tallest of the group and has a curve figure.

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.

At Comic-Con, she cosplays as the Marvel villain Malice. She wears tight leather thigh highs with spikes on her ankles, a black bathing suit with a hole revealing her belly, leather straps all over her arms and face, two red straps with spikes on the end trailing down her back, some red symbols on her chest with a red turtleneck, and spikes on her shoulders.

Loona is extremely lazy and temperamental, rudely insulting all of her coworkers, especially Moxxie, as his professionalism and uptightness clash with the wolf-hound's apathy.

She possesses almost no work-ethic whatsoever and doesn't appear to like her job much, preferring to slack off and entertain herself with her phone or magazines instead. However she's the "lazy but brilliant" kind of worker, as she is, nevertheless, a very useful asset to I.M.P. when she puts in the effort, being very skilled at using Stolas' Grimoire, tracking assassinations targets and even taking on entire hordes of armed enemies. Loona has shown to be very intelligent. She had more common sense than most of her co-workers when it comes to the tactics and work of being professional. She further proves her hidden competence when she's the first I.M.P. member to realize that disguising themselves as humans when roaming Earth would be a good idea and, in the following episodes, Blitzo, Moxxie and Millie actually start following her advice wearing disguises. And she was able to think before attacking in a fight which she did during her fight with D.H.O.R.K.S. Then later after they fought the Cherubs who returned for revenge, she cleverly used her human disguise to make herself smaller taking cover behind a pillar when Collin was firing at her. After defeating them she took the tracking device from Cletus, knowing that it's how they tracked Blitzø and made sure they don't use it again before smacking them back to earth. Then she shows more great I.Q when she corrected Moxxie when he forgot to carry the two on his math.

She is the kind of person who doesn't really show affection that often, after she called Blitzo dad on a post and he noticed, she attempted to write it off as a typo and stopped midway of calling him dad once. That said, she becomes immediately infatuated by Vortex the moment she meets him, barely being able to talk with him. She gets in her first argument with Blitzo when he's trying to "protect" her from Vortex, but started to feel guilty after calling Blitzo an a****le and wanted to apologize to him but he didn't want to listen to her, further showing that Loona hides a softer side behind her rough exterior.

Loona seems to be hiding some deep insecurities and feelings of loneliness, having never had any friends before meeting Vortex and briefly glancing with visible sadness at a picture of an happy family in "Murder Family", which implies Loona does wish to have good relationships in her life, but is unable to due to her tendency to see the bad in people and vent out her frustrations on others, including (and, arguably, especially) those who try to be nice or fatherly to her, like her adoptive father Blitzo.

However, after having been unintentionally friend-zoned by Vortex who tells her how awesome his girlfriend is, Loona didn't resent him and kept in touch with him, becoming great friends with him and going to parties with him, which might be making her more open to people and less hostile, as she's gradually becoming less rude and apathetic towards her coworkers. Loona also understands Octavia for having a distant relation with her father similar to how she has with Blitzo, and telling her that Stolas is doing his best to be a good father.

Once, she showed to be more than capable of both showing affection to and taking care of Blitzo: when he became severely intoxicated at Vortex and Queen Beelzebub's party to numb his pain after having rejected Stolas, she drove and carried him back to I.M.P. headquarters, set him on the couch and covered him with a blanket. When Blitzo shared his insecurities regarding loneliness and asked her if she'd be by him once he met his end, Loona promised him she would, showing her seriousness and true care by willingly calling him "dad".

But she finally opened up her true feelings as she and rest of I.M.P we’re arrested by Satan under the orders of Andrealphus, whom had Loona restrained and put a muzzle on her like a mindless beast despite that she didn't even fight back. Andrealphus had them arrested after revealing that Blitzø illegally stole and used the Grimoire to go into the mortal realm. But just when Blitzø and his crew were sentenced to be executed, Blitzø selflessly begs Satan to spare Loona, Millie and Moxxie to protect them, since they had nothing to do with stealing the book and were simply following orders, in which he does so. Much to Loona’s horror seeing that Blitzø was gonna die unable to say anything to him and his last request was for Millie and Moxxie to take care of her for him. As Loona emotionally breaks down into tears and looks away, but Blitzø was saved by Stolas, who Andrealphus was only using Blitzø to lure him. Just as Stolas reveals he let Blitzø have the book, Loona and the others were set free, Loona and the others tearfully reunite and hug Blitzø, as she calls him “dad”, as she was very scared that she almost lost her dad and glad he’s okay. And later after Stolas was stripped of his power and they take him home with them, Loona hugs Blitzø again and says “I love you dad” to him. Ultimately showing she always loved Blitzø and acknowledged him as her father.
