Highly visible in Republic and Columbia serials of the 1940s, Alabama-born stunt performer/actor Robert Barron never truly got the break he deserved. As handsome as any leading man, the mustachioed Barron was relegated to playing a thug in King of the Texas Rangers (1941), one of the native tribesmen (and wearing a hilarious fright wig) in Jungle Girl (1941) and its sequel Perils of Nyoka (1942), Robert Armstrong's henchman in Adventures of the Flying Cadets (1943), and Ro-Zon, the Kryptonian leader in Superman (1948). In between his many serials, Barron played an assortment of henchmen in B-Westerns and action melodramas.
