The Gray Ghost is introduced in the Batman: The Animated Series episode "Beware The Gray Ghost". Within the series, the Gray Ghost is a fictional character who appears in a television show and in movies, played by actor Simon Trent. As a child, Bruce Wayne would often watch The Gray Ghost with his father, and the dynamic costumed vigilante would be part of the inspiration for Bruce to become one himself later in life, donning the cape and cowl of Batman.
