Powerful super heroes Batman, Robin, Superman, Wonder Woman, Aquaman, Wonder Twins Zan and Jayna and their rascally blue space monkey Gleek battle evil, protect humanity and save the world from unthinkable dangers in these 24 action-packed adventures. These cool cartoon actionfests showcase a gallery of DC Comics heroes and fan-favorite villains like Brainiac and Mr. Mxyzptlk, plus the Hanna-Barbera-originated hero El Dorado. Produced after the Super Friends show ended its run, these treasures were “lost” for more than a decade until they were shown as part of The Superman/Batman Adventures series.
Hanna-Barbera had created a syndication package of the earlier Super Friends series, and these were picked up by various stations across the United States and were typically broadcast on weekday afternoons. Not wishing to compete with the syndication programming, ABC dropped the series from the 1983–1984 Saturday morning television line-up, and for the second time in its run, Super Friends was cancelled.
However, during this period of time Hanna-Barbera continued to produce new episodes of the Super Friends. In total, 24 of the so-called "Lost Episodes" were animated but not aired in the United States that season. The series did appear in Australia uninterrupted. Three of these episodes were aired when Super Friends returned to Saturday morning ABC television the following year.
