Batman and Trent travel to the Batcave, which Trent remarks bears a strong resemblance to the "Gray Ghost Lair" from the television show.
His cameos include the episode of Batman: The Animated Series "Beware the Gray Ghost", playing the toy shop owner, as himself in the episode of The New Batman Adventures, "Holiday Knights", and also as the leader of the Jokerz gang in Batman Beyond, which he joked he did under duress and also joked was "Emmy Award-winning material".
