Captain Z-Ro (pronounced "zero" ) is an American children's television show that ran locally on KRON-TV in San Francisco and KTTV in Los Angeles, from November 1951 through 1953, and was later nationally syndicated in the United States, beginning December 18, 1955 and ending its run of original episodes on June 10, 1956. It remained in syndication until 1960. Modeled on the science fiction space operas popular at the time (cf. Captain Video and Space Patrol), it featured sets and costumes emulating the futuristic designs of Buck Rogers and Flash Gordon.
