Space Ghost (Gary Owens) faces off with "The Antimatter Man" in this short from the short-lived 1981 Space Stars series. The comic by-play between Jan & Jace bookending this story will remind some of another set of siblings who were appearing on another network around the same time, and it makes me think that this adventure might've been meant for a certain franchise on that other network. Agree or disagree?
As you can see, the Antimatter Man was a 1-shot villain who was quickly cured of his condition. Done-in-one stories such as these may need to make a comeback if toon fans want their action-adventure fix in the future, seeing as how the trend today is bending toward light comedy aimed at today's younger generation.
