Mona Lanius, otherwise known as The Painter, is the titular main antagonist of the analog horror, slasher, and crime web series of the same name created by UrbanSPOOK. She is a deranged artist who, alongside her partner, is part of a serial killer duo dubbed "The Painters". With her partner, she was responsible for the horrific murders of many men, women and children across the United States in the 2000s. Mona is the brains behind the operation, responsible for recruiting her partner and paints the paintings of the victims she kills and leaves them for the police to gain traction. Mona is an unfathomably sadistic, deranged, and unrelenting serial killer who takes great enjoyment and pleasure in performing despicable and horrific acts of violence upon innocent people, including men, women and children. She is psychopathic and remorseless, performing each kill with extreme brutality and killing in such a way that implies she wants her victims to slowly suffer as she kills them. She is also a sadist, performing disgusting, violating acts on two of her child victims to derive pleasure, one of which she degraded by calling Cory a "f-cktoy", as well as forcing one of their victims to be raped by a horse they force-fed sildenafil (Viagra), showing how limitless her depravity is and how utterly devoid of empathy and morality she is. She also seems to have a morbidly dark sense of humor considering the names of her paintings tend to be puns on the manner in which she kills her victims. She also seems to have a grudge against law enforcement, as she refers to Ian as a pig, which is an insult for police, and likely tortured Bill Collins to insanity. Despite her psychotic nature and insatiable bloodlust, the Painter is a smart and calculating killer, always making up creative ways to kill people. Although her intelligence and sadism tend to border on arrogance due to her nature as a seemingly uncatchable killer who have successfully evaded the police for ages. This also causes her to slip up slightly and reveal that there's two killers by neglecting to clean their bloody footprints. She also seemingly has no interest in not getting arrested, as there have been seminal fluids belonging to either her or Bill in one of the victims. However when law enforcement catches them, Mona immediately surrenders and tries to get Bill to stand down before he is shot, showing that she knows her limits.
