Captain Video and His Video Rangers (1949)

"Guardian of the Safety of the World", private citizen-scientist Captain Video, assisted by his teenage helper The Ranger and an army of Video Rangers, preserves the peace in the far-off future, fighting the evil Dr. Pauli of the Astroidal Society and a bunch of other baddies (Nargola, Mook, Kul, Clysmok). The show appeared nightly Mon-Fri, featured many outlandish weapons and techno-gimmicks, and was run on a minuscule prop budget.
