A total of 22 episodes were produced for Space Ghost (two segments aired each week), featuring a new assortment of villains including an evil version of Space Ghost called Space Spectre (who came from an alternate universe). The Phantom Cruiser and its Scout Ship were also given sleeker and more modernized looks. Space Ghost often came to the aid of the Herculoids and vice versa (as in the original Space Ghost series’ “Council of Doom” storyline, where they met once). They also frequently crossed paths with the Teen Force, and it appeared that Jan and Teen Force member Kid Comet were dating as well. Elektra made several appearances as well. Gary Owens reprised his role as Space Ghost, but Tim Matheson was replaced by Steve Spears as the voice of Jace, Ginny Tyler was replaced by Alexandra Stoddart as the voice of Jan, and Don Messick was replaced by Frank Welker as the vocal effects for Blip.
