Produced by Creator/HannaBarbera for Creator/{{CBS}} in 1966, the same year as ''SpaceGhost'', Frankenstein Jr. was a gigantic, sentient DoAnythingRobot built and commanded by boy scientist Buzz Conroy. Their base of operations was a mountaintop laboratory run by Buzz's father.

The show's backup segment was ''The Impossibles''. Coil Man, Fluid Man and Multi Man were the secret identities of a trio of otherwise unnamed rock guitarists.

''Frankenstein Jr. and the Impossibles'' was one of the last H-B series animated in the classic Ed Benedict style.
