The Gay Ghost is a ghost who fights crime and evidently is super happy about it. He appeared in the same comic as Wonder Woman and had a lot in common with her, if you know what I mean (I mean they both occasionally turn invisible). He's still the most fabulously dressed character in the whole series, though. Right from the first page, the introductory text warns us that the adventure we're about to read is "one of the queerest in all history":
It retained that spot until the release of David Bowie's "Dancing in the Street" video in 1985.
But what is it that makes the Gay Ghost so queer, exactly? Well, for starters, his superpower is being able to possess the body of "dissolute young American" and renowned pencil mustache enthusiast Charles Collins -- or, as the crime-fighting spirit himself cheerfully puts it, "I can enter your body!"
That's not the only thing he's cheerfully putting in this image.
