25. The Yellow King, 'True Detective'
You know you've got a good villain on your hands when he manages to drive not just his victims but the entire viewing public insane. The figure at the center of the anthology show's first season was the minotaur in its labyrinth of occult references and Satanic-panic creepiness — a boogeyman who turned out to be Errol Childress, odd-job worker and an enthusiastic serial killer of women and children. But this inbred good ol’ boy was best known as the Yellow King, the hallucinatory identity that Rust Cohle and Marty Hunt hunted for for years. It didn't hurt that he was played by Glenn Fleshler, who's carved out a nice niche as TV’s go-to heavy (see Boardwalk Empire, Hannibal, Billions).
