Johnny personifies a character’s intensified sexual urges, visualized as a non-corporeal cartoon cowboy with a yellow hat, shirt, and exaggerated features. He manifests when illness destabilizes the host’s mental defenses, amplifying their libido to disruptive extremes and complicating external intervention. Brash and volatile, Johnny’s confrontational impulsivity actively undermines attempts to restore psychological balance. His behavior and appearance serve as surreal metaphors for internal conflict, symbolizing unchecked desire through disruptive antics. Though referenced in official media, his characterization remains strictly confined to this role, with no elaboration on origins, evolution, or broader significance in spin-offs or canonical expansions.
