The Creeper (Jack Ryder) is a superhero created by Steve Ditko and Don Segall for DC Comics. He is portrayed as a journalist and talk show host, usually living in Gotham City, who gains the ability to transform into the superhuman the Creeper (and vice versa) thanks to experimental science developed by Dr. Yatz. First appearing in "Showcase" #73 (March 1968), his origin was revised in "Secret Origins" (vol. 2) #18 in 1987, then partially revised again in "The Creeper" #1-4 in 1997, then completely reimagined in the six-issue miniseries "The Creeper" (vol. 2), published in 2006-2007.
