The Screen Siren possesses a glowing, ethereal form that shifts like film grain and VHS static, making her seem both present and distant. Her voice echoes with vintage audio distortion, capable of luring players with haunting melodies that warp their perception of the course. She can project miniature horror scenes that visually connect narratives between leagues, and her presence subtly manipulates light and shadow to guide or misdirect players.

The Screen Siren lures players into pivotal narrative moments across leagues, using her seductive power to ensure they deeply engage with their Horror Hall of Fame archetypes and the overarching grindhouse saga.
