Ambassador Magma Episode 52 (Finale): "Space Emperor Goa vs. Ambassador Magma: The Final Battle!"

Ambassador Magma (マグマ大使, lit., Maguma Taishi) is a 1966 tokusatsu television series produced by Tomio Sagisu's P-Productions and based on a manga by Osamu Tezuka, the creator of Astro Boy. It is noted as Japan's very first tokusatsu series to be featured in color, beating out Tsuburaya Productions' Ultraman by one week. In September 1970, the series was adapted in the United States by Bernard H. Schulman's Lakeside Television Company as The Space Giants (and in some English-speaking countries like the United Kingdom, Australia and South Africa, Space Avenger).
