  • Literature: The Osborne Slayer, real name David Thurston Ware, is a teenage high school student who grew bored with his small town and turned to murder to make a name for himself. Planning to make himself infamous as a killer, the Slayer targets his fellow students who are talented enough that they will eventually leave the town and has them brutally murdered. The Slayer intentionally traps them in order to drive up their fear before he mutilates them in a macabre parody of their dreams. Eventually murdering his best friend as well, the Slayer plans to kill heroine Makini Young as well before continuing his murder spree and handing himself over to the police to allow him to live in infamy.
  • Film: Zachary "Zach" Sandford despises his father and the need to hide his privilege so much that he turns to murder to take out his frustrations. Hunting those he views to have dirty secrets, Zach stalks and mocks his high school classmates by wearing masks that copy their faces before knifing them. Even killing one of his close friends, Zach starts to target heroine Makani Young and even tries to frame her for one of his attempted murders. Eventually trapping most of the town in a burning maze, Zach attempts a full-scale massacre of them in his grandest act of evil and even murders his own pleading father to show his psychopathy.
