Stephen King’s The Dark Tower series is filled with chilling villains, terrifying creatures, and surreal horror, but few antagonists are as uniquely unsettling as Blaine the Mono. A sadistic artificial intelligence with a penchant for riddles, Blaine nearly succeeds in killing Roland Deschain and his ka-tet in Wizard and Glass. Given Mike Flanagan’s mastery of psychological horror and his deep appreciation for King’s works, Blaine the Mono is a character that must be included in Flanagan’s upcoming Dark Tower adaptation. His presence would not only amplify the series’ tension but also provide an unforgettable climactic moment that could serve as a season finale or major set piece.
