While adults were rarely if ever seen on the TV show (even Nanny was only seen from the striped socks down), adult characters were often featured in the comic, usually as villains. In one issue, Gonzo was revealed to be an alien, predating the revelation in Muppets from Space. Harvey Comics later issued a Muppet Babies title, consisting of reprints of the Marvel run with new cover art (Harvey's editor in chief Sid Jacobson had presided over the Star line). In addition to two specials in 1992, the Harvey reprints ran from June 1993 until November 1994, totaling six issues in the regular run.
