Adaptations and changes
In 1978, the original Gatchaman was released in South Korea. In 1980, a compilation film called Eagle 5 Brothers (독수리 5 형제, Dokksuri Hyeongje) was made based on Gatchaman II and Fighter. The episodes were later released to South Korea in 1996. Both versions of Eagle 5 Brothers weren't censored. However, there were subtle changes made that are characteristic of remastering which included different hair colors, uniforms, and a complete redesign of Dr. Pandora's child as a boy, despite their gender in the original being left ambiguous. Eagle 5 Brothers was also dubbed into Spanish and released as "Space Heroes" ("Heroes del Espacio"), and alternatively released under other titles including; "Space General Hero", "The Five Eagle Stars" ("Las Cinco Estrellas del Aguila"), and "Five Star Combat Group".
In 1996, Gatchaman II was licensed by Saban Entertainment and combined with the third series, Gatchaman F (Fighter), to create Eagle Riders. 47 of the 52 episodes of the series were translated in the adaptation, though heavily edited to remove violence and other elements found objectionable.[11] Episodes 6, 16-17, 28, and 35 were not used in the translation, and episode 21 (Youth's Broken Wings) was moved and aired in place of the original episode 6 (Attack Of The Pyramid Power).
Elements removed from the series included the Queen Margaret cruise ship disaster in the first episode, along with the transformation of Sammy Pandora into Gel Sadra (called Mallanox in the dub and initially stated as being male). Scenes depicting destruction in cities were also edited to remove references to death, and the Galactor soldiers (now christened Vorak) were said to be androids and would be "deactivated" instead of having been killed. Character names were Westernized in the dub, as well as the entire soundtrack being changed.
To segue the two series together, Gel Sadra's death at the end of Gatchaman II was edited and rewritten so that instead of dying, "Mallanox" is instead transformed further by Cybercon (Leader X) into a new form called Happy Boy (originally Count Egobossler, the nemesis in F).
Eagle Riders only had 13 episodes broadcast in the US, as the translation and editing were reviled by fans of Gatchaman, and the Saban adaptation was pulled from airwaves soon afterwards, not having been seen since.
On December 20, 2016, Sentai Filmworks announced their license for the series. They released an uncut, subtitled DVD set on April 18, 2017.[5] This set is now out of print and no longer available directly from Sentai.
