"Beware the Gray Ghost" is the eighteenth episode of Batman: The Animated Series. It was directed by series regular Boyd Kirkland and first aired on November 4, 1992. The episode features guest star Adam West, best known for his portrayal of Batman in the 1960s Batman television series. West plays the Gray Ghost, a character who bears a strong resemblance to Batman antecedent The Shadow.PlotThe episode opens with a young Bruce Wayne watching a black-and-white television show called The Gray Ghost. The episode cuts back and forth between the flashback and events in the present day, where a crime takes place in Gotham that mirrors the episode: a whirring sound is heard, an explosion goes off, and the police receive a letter claiming responsibility from someone calling themselves "The Mad Bomber". The sequence ends with the Gray Ghost going into action on the television show, and Batman doing the same in reality.In the present day, Batman makes the connection between the explosion and the television episode, but cannot remember what happened in the show as he fell asleep before it was over. He tracks down Simon Trent, the actor who portrayed the Gray Ghost, now unemployed and short of money. In an act of desperation after trashing his display cases in frustration, Trent attempts to sell his Gray Ghost memorabilia to toy collector Ted Dymer. Later that night, Trent awakens to find his memorabilia back in his apartment and his display cases restored. Trent also finds a letter from an anonymous person to meet in an alley. When Trent and Batman finally meet, Trent is unable to recall the details of the episode featuring the Mad Bomber and states that he does not want to help Batman and just wants to be left alone. After a second explosion at the Gotham Bank, Trent relents and gives Batman a copy of the episode from his personal archive (all production copies were reportedly destroyed in a fire 20 years before).
