The program was shown in English internationally as part of Jim Terry's Force Five lineup, and was also broadcast in Latin America as "El Gladiador" as part of a 4 anime mecha show called "El Festival de los Robots" (with the other 3 being "Starzinger", "Magne Robo Gakeen" and "Kotetsu Jeeg", known as "El Galactico", "Supermagnetron" and "El Vengador" respectively). The Jim Terry dub was released on video in the UK by Krypton Force under the name "The Protectors", though the first volume of their "Formators" series actually contained Gaiking episodes instead of episodes from Jim Terry's "Starvengers". Another dub was produced in the late 70s by M&M Productions in Hawaii, who also dubbed "Mazinger Z" for Toei as a potential test for a US release. Isao Sasaki did the English versions of opening and ending songs for this dub. Of this dub, only the eleventh episode survives.
