The Dark Tower Series Needs This Sinister Character

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.

If Flanagan is looking to capture the essence of King’s multiverse-spanning epic, he will need to translate its most bizarre and terrifying elements into live-action. Blaine, a rogue AI train with a twisted sense of humor and a love of destruction, represents one of the most high-stakes moments in the series, pushing Roland and his crew to the limits of their intelligence and resolve. Leaving him out would be a huge missed opportunity, both narratively and thematically.

Blaine the Mono: The Perfect Horror Villain

Blaine the Mono is unlike any other villain in The Dark Tower series. While the Crimson King is the ultimate big bad and Randall Flagg (or Walter O’Dim) serves as Roland’s primary adversary, Blaine is something else entirely—a machine gone insane, a remnant of a lost world that has developed a cruel and childlike sense of amusement. His role in Wizard and Glass is one of the most memorable in the series, as he challenges Roland and his ka-tet to a riddle contest with their lives hanging in the balance.

Flanagan excels at crafting slow-burning horror that gets under the audience’s skin. Blaine’s introduction would be a perfect showcase for that talent. Imagine an episode where Roland and his ka-tet enter a seemingly lifeless monorail station, only to hear Blaine’s voice echoing through the empty halls. As they board the train, what begins as a moment of relief quickly turns into a nightmare when Blaine reveals his true nature. The transition from eerie stillness to full-blown existential horror is something Flanagan could execute masterfully.

The Riddle Battle as a Season Finale

One of the defining moments of Wizard and Glass is the riddle contest between Blaine and the ka-tet. The stakes are impossibly high—if they lose, Blaine will crash himself at top speed, killing them all. The battle of wits between the group, and Blaine is as tense as any action sequence, showing off the ka-tet’s dynamic and forcing them to outthink an enemy that is more powerful than they are.

This scene would work perfectly as a season finale for Flanagan’s Dark Tower adaptation. Ending a season with the travelers desperately trying to stump Blaine, with the AI’s voice shifting from amusement to rage, would make for one of the most thrilling cliffhangers in television. The scene is naturally cinematic—flashing red lights, increasing speed, Eddie using absurd humor to throw Blaine off his game, and Roland’s intense focus as he tries to keep them all alive. The slow, mounting dread as they realize Blaine is nearly impossible to stump, followed by the catharsis of finally breaking his logic with bad jokes, would be the kind of gripping, unconventional climax that fans would never forget.

Bringing Blaine to Life on Screen

Adapting Blaine the Mono to live action would be a fascinating creative challenge. He is not a physical antagonist but rather a voice, an intelligence embedded within the train. However, Flanagan has already demonstrated his ability to create terrifying presences through atmosphere and sound design alone (The Haunting of Hill House and Midnight Mass being prime examples). A fully CGI Blaine, combined with expert voice work, could make for one of the most unsettling antagonists in television.

Flanagan’s previous adaptations of King’s work (Doctor Sleep, Gerald’s Game) have shown his respect for the source material, and his commitment to the Dark Tower saga suggests he will take the time to get it right. Blaine’s voice, tone, and personality are crucial to making the character work—he is both playful and psychotic, charming and terrifying. A voice actor with a mix of unsettling joviality and creeping menace (perhaps someone like Mark Hamill, who has played sinister AI before) would be perfect for the role.

Blaine the Mono is one of The Dark Tower’s most fascinating antagonists, and his inclusion in Mike Flanagan’s adaptation is essential. His presence would add an element of psychological horror, create a thrilling set piece, and provide one of the most memorable finales of any season. Flanagan’s ability to blend horror, suspense, and character-driven storytelling makes him the perfect person to bring Blaine to life.

Leaving out Blaine would mean losing one of the most unique and terrifying moments in The Dark Tower saga. But if Flanagan embraces the full weirdness of King’s world, Blaine the Mono could become one of the most iconic horror villains ever seen on television.
