Robot Taekwon V (Korean: 로보트 태권 V) is a South Korean animated film directed by Kim Cheong-gi and produced by Yu Hyun-mok, the prominent director of such films as Obaltan (오발탄; 'Aimless Bullet') (1960). It was released on July 24, 1976, immediately becoming a hit in the late 1970s, and consequently inspired a string of sequels in following years. Robot Taekwon V was not only a successful science-fiction animation for children but also served as powerful political propaganda for ideologies such as nationalism and anti-communism in the 1970s under the military regime of President Park Chung-hee. Decades after the film was initially released, the digital restoration of the film was completed in 2005, and since then the Robot Taekwon V character has built its own branding as the Korean science fiction hero as well as the symbol of nostalgia for Korean people who grew up with the film series. Robot Taekwon V was released in the United States in a dubbed format under the name Voltar the Invincible.
