The Gray Ghost was an actor named Simon Trent who portrayed the character in "The Gray Ghost" TV series. After the series was cancelled, Simon got typecast decades later and couldn't get other roles as everybody thought of him as the Gray Ghost. He donned his costume again to help Batman in a case that involved someone copying the parts of "The Mad Bomber" episode. The two of them discovered that Ted Dymer was behind it and were able to defeat him.
After the incident reached the newspapers, the Gray Ghost was thrust into the spotlight for his role in capturing the Mad Bomber causing a resurgence of popularity for his show. Shortly thereafter, a major home video release of the long lost TV series was made from Trent's personal film collection restarting his acting career and making him a wealthy man. During a public video signing in costume, Bruce Wayne acquired Trent's autograph and subtly revealed to his hero his own secret identity as Batman which pleased Trent to no end.
- In Batman: The Animated Series, he is voiced by Adam West who also played Batman in the 1960's television show of the same name and himself in LEGO Batman 3: Beyond Gotham.
