The World's Greatest Superfriends premiered on ABC Saturday, September 22, 1979 with the episode Rub Three Times for Disaster; the first of eight 30-minute episodes. This incarnation of the Superfriends followed the very successful run of Challenge of the Superfriends, which featured The Legion of Doom. In that series, the Superfriends battled the same foes in each episode. In The World's Greatest Superfriends, there is a different enemy in each episode. Stanley Jones reprises his role of Lex Luthor in the second episode of this series in a nice bit of continuity. The Wonder Twins and their space monkey Gleek also return after taking a hiatus during the last series.
