Englund will play a character known as "Dr. Robert," a medic for hire that mends injured demon hunters and other unsavory individuals who would rather not visit the emergency ward. Executive producer/showrunner Sera Gamble had this to say about Robert Englund's appearance:
"Hunters often find themselves in situations where they need medical attention but can't exactly stroll into an ER. Robert plays an unlicensed doc who makes his living stitching folks up on the down low. One of our guys goes to him with a life-or-death problem."
