Sight and Sound: "Conquerors of the Future"

"Banded together from remote galaxies are thirteen of the most sinister villains of all time--the Legion of Doom--dedicated to a single objective, the conquest of the universe! Only one group dares to challenge this intergalactic threat: the Superfriends!"

"Conquerors of the Future," an action-packed installment of Hanna-Barbera's unequivocally entertaining Challenge of the Superfriends featuring Jack Angel as the voice of the Flash, aired on the Saturday morning of 18 November 1978 on ABC. In the episode's epic conclusion, a series of convoluted clues left by the Riddler reveal that the Legion of Doom has conquered the world sometime in the far-flung future. Because they're each capable of penetrating the time barrier, Superman, Green Lantern, and a surprisingly airborne Flash band together and charge ten thousand years into the future to challenge their united foes and restore the timeline. The episode features not one but two of the scarlet speedster's Rogues as members of the despicable Legion of Doom: Stanley Ralph Ross voices Gorilla Grodd while Don Messick provides the voice of Captain Cold. Due credit to the underappreciated King of the Seven Seas, however; in animated form, we must admit none of the scarlet speedster's supervillains could ever be as menacing as the terrifying Black Manta! After their plot to overtake future civilizations is foiled, these cowardly would-be conquerors are taught a lesson they won't soon forget: "Once you've started a battle with the Superfriends, you've got to finish it!"
