Matt McColm as Johnny Domino/Night Man, a saxophonist who is struck by lightning while playing inside a cable-car. As a result, his brain gains
radio-like properties, able to "pick up" certain mental frequencies. He is now attuned to the "frequency of evil", which enables him to "hear" evil thoughts and evil-doers wherever he goes. He wears a bulletproof bodysuit, as well as an
anti-gravity belt that enables him to
fly, a cape with holographic
camouflage-style invisibility properties and a mask with a round red lens over his left eye, which gives him the ability to see/aim in the dark and fire a laser beam. •
