Dr. Miranda Voss was the facility's lead plasma researcher until a catastrophic containment breach flooded her lab with ionized blood samples during a critical experiment. The plasma-charged hemoglobin rewired her neural pathways, transforming her from a brilliant scientist into a calculating predator obsessed with the electrical properties of human blood. Now she hunts through Art Dye's fairways with makeshift weapons crackling with residual plasma energy, seeking fresh subjects for her twisted continuation of the research.

Plasma Psycho possesses enhanced reflexes from neural plasma exposure and can generate small electrical discharges through direct contact with her victims. Her blood glows faintly with residual ionization, and any metal objects she touches become temporarily electrified, making her improvised weapons particularly dangerous. The plasma corruption has made her nearly immune to pain while amplifying her predatory instincts, allowing her to track players across the course with disturbing precision.

She serves as the facility's most dangerous human threat, representing how scientific ambition can corrupt the human psyche into something monstrous. Her presence on the fairways forces players to remain constantly vigilant, as she embodies the unpredictable violence that lurks within the laboratory's contaminated environment.
