In this half-hour packed with the adventures of two of the most unusual animation creations of the legendary Hanna-Barbera studio, Buzz Conroy is a heroic boy-genius who builds the powerful robot, Frankenstein Jr. When the Ghastly Genie, the Junk Man and other evildoers get up to their old tricks, "Frankie" and his young creator crank into action. The crime fighting coalition continues with the Impossibles – a group of superheroes disguised as a beatnik rock group. At the direction of "Big D," Multi Man, Coil Man and Fluid Man make hot-rockin' musical justice, thwarting thieves and corralling crooks with their transformative powers. Classic cartoon fun is brought to life in this collection of 18 supercharged episodes.
